Chapter 399 Bullying You with Junior High School Physics

The one that caught my eye was a ship, clearly a wall

The giant building is about 30 meters long (about 90 meters), and there are 24 wheel paddles on both sides of the hull. Its body is about eight or nine meters above the water surface. When it moves, the 24 wheel paddles make huge, rustling sounds of breaking water. This sound, in this era, is roughly equivalent to the roar of the head of a train steam engine.

How long is ninety meters long? A football field removes two penalty areas from both sides, which is about the length of this building.

More than one such giant warship has arrived.

Fang La implemented the Manniu strategy. Six huge tower ships lined up on the river, and the same flexible giant loach ships, with sixteen oars standing on both sides of the hull. They filled the gaps between the various tower ships, and turned the hull quickly to block all possible gaps.

In the gap between these giant sea loach ships, medium-sized eight-car ships (eight oars), four-car ships (the "Flying Tiger Battleship" commonly used by the navy in the Song Dynasty, with four oars next to them, each of which is eight oars (8 blades)), two-car ships (two oars), and multiple oars (commonly used by the southern navy in the Song Dynasty, with 42 oars and 200 armored soldiers, and rivers, lakes and seas can be used), stars occupy the entire main channel in the heart of the river, forcing the head naval warships from the opposite side to sail to the riverside.

The water by the river is shallow, and once it is forced to the river, there is less room for maneuver.

"Is this... Ducai craft Gao Xuan captured by Fang La? Why is the ship built by Fang La exactly the same as the warships designed by Ducai craft Gao Xuan?" Zhang Heng asked in a hoarse voice.

The most famous shipbuilder in Hangzhou was the imperial court's chief official. The capital craftsman Gao Xuan was said to be good at making giant boats. When he was wearing a large number of fast sailboats, he wanted to invite Gao Xuan to give him some advice. Who knew that the court officials were arrogant and did not even have to wear this little gentry, which made the matter end.

The staff officer swallowed hard and replied: "The family business of Gao Xuan in Dui is in Hangzhou. You should not be able to leave. Maybe you will be captured. "The General of Wu Jing" records such a style of ship. Even if Gao Xuan is not captured, as long as there are literate people in Fang La's army, they can still be made with "The General of Wu Jing". This ship is rated to carry 200 armored soldiers, 200 archers, and more than 300 oarsmen. The hull is tall. There is a one-person-high arrow block on both sides of the ship. The arrow block is erected, and the crossbow cannot be injured... Lord, let's retreat."

Zhang Heng swallowed nervously and asked, "How deep is the river here?"

The staff officer immediately replied: "I sent someone to measure it some time ago. The water depth along the main channel is about ten meters. Our fast sail (ship) is now 5 meters in water. The sailors are still walking and measuring, so there should be no worries about stranding... But the other party blocked the main channel. If we avoid the outside, we don't know if the water depth is enough."

Zhang Heng was still thinking. At this moment, the staff officer in charge of contact shouted: "The deputy boat raised the flag, just one word: bumped."

Zhang Heng suddenly realized and asked hurriedly: "How wide is the other party's boat?"

The length and width ratio of all ancient Song Dynasty ships that salvaged water in modern times did not exceed one to three. Even the legendary lucky ships that Zheng He traveled to the West did not exceed one to three. This was done to try to make the length of the keel bones so that the ship could carry more cargo. Gao Xuan, a Song man, did not get rid of this habit, and only heard the staff officer answered: "The enemy's tower ship is more than ten feet wide. Sir, he must carry seven or eight hundred combatants, but he must not have such a wide cabin."

Zhang Heng smiled: "How long is our boat?"

The staff officer was stunned. After a while, he understood and said loudly: "Sir, please give me the order."

The fast sailing boat Zhang Heng was riding was also 90 meters long.

For such a long ship, there is basically no suitable giant wood for keels, so Yizhou Shipyard had to "invent" the iron keel technology. Similarly, Jiangnan has been developing for more than a thousand years, and almost no trees with bowl thickness in Hangzhou can be found in the place of Hangzhou. In a hurry, the Fangla navy could find a giant wood of 90 meters long to be keels. Its keels can only adopt mortise and tenon splicing technology.

This kind of mortise and tenon splicing keel is similar to the warships that the Mongols rode on when they attacked Japan in the Yuan Dynasty. In fact, those warships were made by captured Song ship craftsmen. Modern propaganda blows the "monomering and tenon splicing technology" like flowers, but the reality of the sinking of the Mongolian fleet tells us: Perhaps mortise and tenon technology is very grand, and any great and glorious business means unreliable, and the same is true for mortise and tenon ships.

As a ship, its only problem is that it is not suitable for use as a ship, and a slightly larger impact and storm can make it sink.

"Fire the cannon", Zhang Heng bit his back teeth and ordered. His ship was very precious, and he bumped directly into it. Although it could theoretically crash Fang La's ship,... whoever was heartbroken. Fang La's things were all robbed others, so it was not heartbroken. The warships of the head-pulling navy were all tools for making money - how could porcelains take the initiative to collide with clay pots?

If you don’t need to hit it, you can use a cannon. A big iron lump of shells will always harm people by hitting them.

As soon as he finished speaking, he heard a rumbling sound from the opposite building ship that was even more thoughtful than a cannon. Several huge stones rose from the ship, drew an arc in the air, and fell in the middle of the river not far from the fast sailing ship, causing the same huge waves.

Immediately afterwards, Zhang Heng's cannons also sounded. From the bow to the stern, the ten cannons equipped on the ship emitted a louder roar than the stone-casting cannon, and emitted thick smoke...

At this time, the artillery shooting was no longer needed Shi Chuan personally commanded it. Ten runs started one after another. Zhang Heng's boat had already sailed to the edge of the main channel. The sailors on the boat raised a copper whistle and blew a sharp whistle. The sailors on the deck grabbed the ropes beside them. They leaned a little. Zhang Heng slammed the steering wheel. The fast sailboat tilted the hull with an unimaginable inclination and began to turn violently...

This inclination even the warships of the Fang La navy opposite were screaming in unison. If their boat had this inclination, it had already been overturned. However, the fast sailboat made of iron keels had the center of gravity on the central axis. The trunk was filled with iron shells and the center of gravity of the ship was extremely low. The fast sailboat was like a graceful swan and it was turned around just slightly beyond the main channel.

So, after the Fang La navy was amazed, he also gave a compliment. Although they were enemies, everyone was eating on water and couldn't help but cheer for the graceful figure of the fast sailboat.

When the ship completed the steering, Zhang Heng raised his eyebrows proudly and smacked his lips and said, "Our favorite is to turn around. It's so endless to play."

After smacking his lips, Zhang Heng ordered loudly: "Looking hands, inform the shelling effect."

"Three enemy ships are all at the bow."

At this time, the other fast sailboat that Shi Chuan was riding also entered the appropriate shelling position. The cannons on the boat started running without hesitation. The smoke of gunpowder rolled, and Shi Chuan's shelling was completed and turned around smoothly. The two large cannons also entered the shelling position in the T-shaped shape (called the "lower shape" in the Song Dynasty. In ancient times, the word "lower" did not have the point below, which also means "lower"). The two gunboats fired without stopping the cannon. At this time, the two fast sailboats were on the left and right, and they were traveling in the opposite direction in an extremely symmetrical direction. The gunboats entered the shooting position and immediately began to turn. The hull was crossed and the opponent's La naval army front formed a "t" shape with the fast sailboat in front, and began to spit out fire and smoke violently.

One after another, the warships of the Navy's head entered the "t" shape and the two fleets were already very close. The fleet of Shizhan happened to be outside the range of the stone-casting cannon and within the range of the long crossbow. Fang La navy's efforts may bring the warships of Shizhan, but this distance is like a cannon that is on the chest. In addition, Fang La's fleet is densely arranged, and almost no one can't hit.

After the cannons, the broken wood flew across the head of Fang La's fleet, and the splashing wooden thorns caused screams. The huge chemical kinetic energy made the warship shaking. The crossbowmen on the ship were unstable, so the fired crossbows flew everywhere.

After returning to the center of the lane, the fast sailing boat ran towards the tail of the fleet like a thirsty horse running in the spring. Zhang Heng stood on the podium and thought for a while, and immediately said: "I inform the fast sailing boat opposite, our ship has a draft. Please exit the battle sequence list."

Shi Chuan sent a signal of "agree". Then, the two fast sailboats turned direction again, stopped at the waist position of the "t" font, and observed the battle situation at close range.

The tower ship was indeed an unbalanced ship. After three rounds of artillery, two tower ships had already entered the bow of the bow. One tower ship was out of control and overturned, causing several giant sea loaches to be exposed in the array of warships. At this time, Zhang Heng directed the small sea loaches from Haizhou to step forward and bombarded the two oars of the sea loaches. Immediately, the wooden leaves of the sea loaches were stuck after being bombarded. The lost power had to drift down the water helplessly.

After the big loach was paralyzed, Zhang Shun began the famous "Yizhangqing" operation - translated into modern language: wave-making action. In modern times, our water police patrol boats are often overturned by waves created by fishermen. When those modern water police encounter fishermen, the first thing they do is to put out slogans: wave-covering patrol boats is an illegal act. These ancient warships in front of us are worse than modern water police boats, and Fang La navy, who does not pay attention to controlling the center of the ship, suffered a great loss from Zhang Heng.

I saw a series of small sea loaches quickly approaching the Fangla naval fleet, but they braked suddenly outside the range of the Fangla naval army's stone-cat guns, crossing the hull, creating a wave of the same size as the hull, and then turning around and leaving. Immediately afterwards, one after another, one after another, adding the waves, making the waves bigger and bigger, the troughs lower and lower, and the calm river surface suddenly surging.

In the past, Zhang Heng was a pirate in Dengzhou area and did not have any powerful weapons on the ship. However, by just using this move to "make waves", he overturned the official warships with huge stone-towed cannons on the ship one by one, so that the local people called it "Yizhangqing", which means that this guy is like a poisonous snake. No matter who provokes him, he will be careful whenever he is targeted.

Since arriving in Haizhou, Zhang Heng has found that the center of gravity of Haizhou's warships is lower and paying special attention to ship speed, so he is even happier. Now he has something to do and can make huge spikes in the sea. Even if the ship is not equipped with any weapons, it is probably not a problem to rush across the South China Sea with his own skills.

Creating big waves is a technical job, that is to say: if you do this kind of thing, you either learn without a teacher, or you need to have the knowledge level of a second-year junior high school student, know the "climb superposition effect" in physics, and just make a wave at the trough to superpose the peak - otherwise, the peak will definitely be weakened.

The water surface of the Yangtze River is very calm, and the wind direction on the river surface does not change much. Fang La's boats are all flatbed boats, with shallow drafts, but the water buildings are huge and towering - that is to say, the center of gravity of the ship is several meters above the water surface.

Two waves of waves surged over, and the warships of the Fang La Navy began to shake violently. Then, the peaks of the waves were superimposed, and the peaks became higher and higher. The warships of the Fang La Navy were shaking more and more frequently. The inclination of the outermost tower ships became greater and greater, and the hull was back to the right time longer... Finally, the two tower ships began to tilt a huge tilt, slowly surpassing the maximum inclination at a speed visible to the naked eye, and slowly falling towards the heart of the river.

Cargo ships sailing on the river surface are not like sea ships. Because of frequent wind and waves, sailors have the consciousness of fixed cargo. The river surface is calm, and even if there are waves, it will not take long, so there is no need. This causes the hull of the river ship to tilt exceeds a certain angle and the cargo full of the ship rolls and causes the center of gravity to shift, the tilt of the hull is acceleration. Once the hull exceeds a fixed inclination, overturning is inevitable.

Everyone knew that the sinking of these two giant tower ships was inevitable. The hull quickly lie towards the water surface. The soldiers fell on the deck like dumplings, screaming in horror everywhere. With a desperate and deafening cry, a person wearing golden helmet and golden armor fell from the five-story tower. In the blink of an eye, the huge hull of the tower ship was heavily slapped on the water surface, and the golden helmet and golden armor were discharged into the bottom of the river...

The Fang La navy had no time to mourn. The sinking of the two tower ships caused the gaps exposed by the tight formations of the Fang La navy's outer edge. A huge surge instantly rushed into the interior through this gap. At this time, Yi Zhangqing still relied on his skillful wave-making skills to continue bullying and oppressing the Fang La navy. Zhang Heng jumped on the platform and shouted loudly: "Good job, boys, continue."

Of course, we have to continue. The four-ship group of loach ships continued to advance quickly. Because this made the Fang La naval soldiers only fight against the surge and do not care about controlling rods, stone-capping cannons, or crossbows, so the loach ships that leaped the heads of the naval army can get closer. When they rushed to the side of the Fang La naval ship, when the ship fell into the wave valley, they suddenly turned the rudder and crossed the hull. The force of the ship's sudden brakes allowed them to create another wave peak. The wave peaks quickly superimposed on the next wave. The surged peaks quickly lifted these little loaches to the sky, so that the top of their peaks could even look down at the deck of the Fang La naval army from a high point.

Of course, the deck of Fang La navy was panicked. Those large long-range attack weapons, catapult lathes and crossbows, all slowly moved on the deck. The archers of the Arc, who were originally standing on both sides of the ship, began to panic and take off their armor and throw their weapons. If they brought these things, if they fell into the water, they would change their surname to Chen and their names to the end.

After taking care of this one and no matter the other, Fang La naval army was busy taking off its armor and forgot to hold the cables to fix its body. Often, the armor was half taken off, and the feet were unbalanced, and people were no longer on the deck. At this time, the tower ships outside the Fang La naval army were basically unable to see them. They were either broken by artillery fire or warships fell to the middle of the river. Without the huge body of the tower ship covering the wave peak, the giant sea loach ships next to the tower ship also began to sway violently, and the ships near the giant sea loach were frightened to avoid them. So, the formation of Fang La naval army advancing like a wall immediately became scattered.

After watching the battle, the people and baggage personnel on the north shore immediately cheered through the sky.

There is no suspense to victory

Since the war between the two sides, the Fang La navy has relied on its huge hull and its strict formation, pressing down the current step by step, forcing the Haizhou navy to retreat step by step to obtain shooting time. This time, the strict formation was torn apart and the form was reversed. Even the ignorant people could judge that the balance of victory was tilting towards the Haizhou army.

The Fang La navy began to bleed, but they had not finished their blood.

The giant rushes into the Fang La formation and begins to ravage the soy sauce crowd standing in the back row. Immediately, the three tower ships in the second detachment began to shake hugely... and behind, more tower ships received warnings and began to turn their bulky bodies to try to leave the fleet to avoid the giant - this length-to-width ship looks fatter than most bathtubs. When it begins to turn around clumsyly, the nearby ships cannot dodge and are knocked over several ships one after another. As a result, the Fang La navy dodges more violently and the formation becomes more scattered.

Taking advantage of his illness, after the ships of Fang La Navy's peripheral army crashed, several flexible little loaches, like wolves, crawled into the Fang La Navy's fleet like a gap exposed by the other party, began to rush around. Then, the gunboat began to rely on its tall bodies to drive the waves through the waves. When the gunboats were raised, the gunboats were majestic and majestic, sweeping the busy sailors on the deck with their shotguns, while the sailors on the putting up the palm of their hands and thundered to draw the fire bottle.

The navy is sowing flames.

Every wave peak rises, there is always a majestic gunship on the top of the wave peak, roaring with fire and smoke. Whenever the Fang La navy wants to fight back, the wave peak sends the Path Head Navy warship into the wave valley. The huge wave peak covers the Path Head Navy hull. Taking advantage of this time, the Path Head Navy quickly loads shells and prepares for the next wave attack. When the next wave peak comes, they spit out flames and metal storms again, rushing to the top of the wave...

There are warships of the Navy Army on each wave peak, which means that the Navy Army's offensive is like a wave, one after another, and it quickly advances into depth by riding the waves. At this time, the Fang La Navy Army has no organized resistance. Where the waves pass, torches are ignited, and the Fang La Navy Army is burning.

The tall Fang La navy could not stand the torture of heat waves. Near the fired ships, no friendly ships thought of rescue, turned around and avoided them, making the formation even more messy. On the other hand, the Haizhou Army relied on individual combat weapons to sharply reach the center of the Fang La fleet deeper and deeper...
