"**, how far is it from Guangzhou?" After dark, the fleet anchored at an unnamed island at night. After a simple dinner, Zhao Bing called ** and asked.?

"Your Highness, there's still about two more days to go." ** took out a pamphlet and flipped through it and replied.

"Well, our journey down will be smooth sailing, and we should still have enough time." Zhao Bing said after a mental calculation. He knew that in ancient times, due to the lack of technology, there were still limitations in geographical understanding, and it was difficult to navigate the vast sea.

There are reference objects. Therefore, it is difficult to calculate the voyage, so the time is calculated by burning incense or an hourglass, and the day and night are divided into ten watches, so the mileage is calculated by watch. Therefore, watch is not only a unit of time, but also includes the mileage of the voyage. In this case, each watch

About sixty miles.

"Yes, Your Highness, we will go to sea at midnight tonight and we will reach Haikou before dawn tomorrow." ** said with certainty.

"**, can you lend your book to me to read?" Zhao Bing pointed to the book in **'s hand and said. Primary school students in previous lives all knew that distance multiplied by time, and when a ship travels on the sea, the tide will go up and down.

The speed of travel varies, and these uncertain factors often make it difficult to calculate the voyage. The ancients did not have modern advanced instruments, but they could measure the ship by throwing wood, and roughly calculated the relatively accurate voyage by adding the time it took to burn incense.

The roads and so on were combined to form a nautical chart and a road map, and Zhao Bing concluded that the booklet in the hand was the nautical chart.

"Your Highness, this..." ** hesitated and said, "Your Highness, can you let your subordinates see Bai Ri's clairvoyance?"

"Haha, you also negotiated terms with me, okay, I will agree to you!" Zhao Bing understood after thinking for a moment, and handed the telescope to the lady, who immediately handed over the book that was as precious as life.

The two of them immediately took the chart and started playing with it.

"Your Highness, can you understand?" ** looked far away and close up, feeling dizzy. He rubbed his eyes and raised his head and suddenly saw that the young prince was flipping through the book and writing down something with a pen, as if he was calculating something.

"Is this difficult?" Zhao Bing asked with a wink and a smile. He knew that it was precisely because of the uncertainty of sea conditions. Therefore, there were two prerequisites for calculating the voyage in ancient times: one was to measure; the other was to understand the wind.

People who understand the speed of communication and the flow of water. But it is precisely because of the human factors involved that each chart is different and forms its own secret book.

This also led to Zhao Bing thinking that the young prince did not understand this knowledge and could not understand the secrets even if he was shown it. However, he never imagined that there was an expert hidden in it. Zhao Bing only needed to determine the time and flow of the incense he used.

Depending on the direction of the wind, it only took a matter of minutes to decipher his chart. What bothered him was actually just the 'inexplicable' place names in the chart.

"Then...then I won't change it!" ** suddenly stretched out his hand to grab it, but looking at Ni Liang on the side, he retracted his hand again. He was really afraid of this silly boy. Who among the guards dares to speak to His Highness?

No, he would fall out immediately, let alone snatch things from His Highness's hands. But he really didn't want to lose generations of hard work just because he was greedy for toys, and he also knew that this was how he could stand out in the military.

capital.

"I will not take away someone's love, so I give it to you!" Zhao Bing smiled and returned the booklet to her. In fact, Zhao Bing had learned something in this area in his previous life, but he had never seen the real thing. Now he can see it at a glance

He will understand the principle next time. He can use this as a sample and combine it with existing tools to make a more accurate and standardized chart. Therefore, this chart is meaningless to him now. It is just for him temporarily.

If you can't take care of it, you have to rely on this old thing.

"This..." The prince easily agreed to his request, but ** hesitated and froze there.

"Okay, the telescope is more useful in your hands. You can use it first, but be sure not to damage it. This is a unique thing in the world." Zhao Bing thrust the booklet into the embarrassed woman, turned around and said

"Wang De, please invite some counselors and generals to discuss the matter, and the fleet is ready to go!"...

…………

On April 10th, the Shuaifu fleet, which had been sailing southwest, suddenly turned southeast and entered the Lingding Ocean. At midnight, the fleet sailed into the Pearl River Estuary. Due to the Pearl River's thousands of years of erosion and sedimentation, many sandbars and sandbanks have been formed here.

Qianwan. Due to the narrow river channel and many rocks, in order to avoid stranding, the fleet moved in tandem, widening the distance and lowering the sails at half speed. More than 200 ships were like a long winding dragon.

The fleet arrived at Longwan, and the front army continued to move forward to prepare to pass through Shuiguan and approach the city; the right army hid behind a sandbar to the east. After the front army attacked, they entered the east water trench from the Pipazhou waterway to capture the right wing.

The left army cooperated with Jiang Qiu's commander Yi Yong to capture the towns of Fuxu and Shimen, waiting for an opportunity to capture Zuoyi City. After the front army captured the port, the Chinese army cooperated with them to annihilate the Chima exploration army stationed outside the city; the rear army

They are responsible for protecting Wang Jia and keeping waterways open. At the same time, they serve as a reserve force and are ready to support the armies at any time.

Zhao Bing's boat was moored in the middle of the river. In order to prevent him from running out to 'watch the fun' again, he was strictly prohibited from leaving the cabin. However, he also knew that Wang De and Ni Liang alone could not despise the prince, so they

If not, His Highness would have tricked him into sneaking out together, and he might even have gone to the front to join in the fun. As for the adults on the ship, Zhao Mengjin was sent to the front army to directly command the battle, and Pan Fang, the transfer deputy, was in the rear army to supervise the battle and carry out the punishment.

Gao Yingsong went to the right army to supervise the battle, leaving only Ying Jieyan to take charge of the central army. Therefore, Deng Guangjian and Yuan Miao could only be allowed to "accompany" each other in the cabin.

At present, one of the two people was sitting at the door of the cabin, twirling Buddhist beads and chanting sutras with his eyes closed. The other did not force him to endorse the book. He was holding a book in front of the candle and shaking his head. Looking at these two silent gourds, it was his master, Zhao Bing.

He couldn't chat even if he wanted to. Because of the light control, all the lights outside the cabins were turned off. He didn't dare to open the window, so he could only open a narrow slit in the porthole and look out.

At this moment, the half-curved moon has set to the west, and the stars in the sky reflect the stars on the sea, twinkling with the waves. Occasionally, the barking of dogs can be heard from the sandbanks on both sides, but there is no light. I wonder if it is because I am used to boats mooring at night.

He was still sleeping soundly, and not even a single person could be seen. The sound of the boat breaking through the water was extremely abrupt in the silent night, which made people jump with fear.

"Your Highness, the tide has begun to rise!" Zhang Jin walked into the cabin and reported.

"Yeah." Zhao Bing hummed and understood. He didn't ask any more questions and still looked out the window, but his heart was hanging. Today is the seventh day of the Lunar New Year, and it is not a high tide day. It is not conducive for the fleet to take advantage of the situation. But

Because the intelligence received showed that the enemy troops had begun to evacuate, and now only the rear troops in charge of the baggage were still in the city to collect food supplies before setting off. If they waited any longer, Guangzhou City would have been plundered, and they would have lost their original intention of attacking the city, so

It can only be started in advance.

According to the agreed battle plan, the Shuaifu army prepared to fight on the tenth day of the lunar month. The fleet entered the seaport under the cover of night, and when approaching the city, it had to pass through the water pass. They planned to use a sneak attack to seize the pass. However, the water pass was equipped with a city wall.

There was also a navy stationed there, so it was very difficult to get close. It was not easy to win by secret attack. Therefore, they decided that if they could not succeed in secret attack, they were going to take advantage of the rising tide and use the tide to ram open the water gate with a large ship to force a breakthrough, and then divide their forces to seize it.

Landing at each port 6. This plan obviously has major flaws. Once a force attack is used to seize the pass, the Tanma Red Army stationed outside the city will inevitably be alarmed.

According to the Mongolian military system, every time there is a war, soldiers are selected from thousands of households, hundreds of households and ethnic tribes to form elite troops to serve as vanguards in field battles and when attacking castles. Unlike the Mongolian army, which is composed of soldiers from thousands of households each.

It was composed of a mixture of soldiers selected from various ministries. After the war, this army was stationed in the conquered areas and was called the Tanma Red Army. Therefore, they can be said to be warriors who can compete with a hundred. It is better to stay here than stay here.

The new auxiliary army composed of the surrendered troops of the Song Dynasty was several times more powerful, and it was the biggest enemy that the Shuaifu army had to face.

Zhao Bing knows best how many pounds the Shuaifu army has. If they are on the water, they may still have the strength to fight, but it is really hard to say that they can escape unscathed against the Tanma Red Army on the 6th. This is not his arrogance. The Song Army in the Battle of Quanzhou

When Quanzhou was about to be captured, Chaodu only brought 3,000 troops to help and defeated hundreds of thousands of Song troops. In the end, he was able to escape with the help of heroic cover. Therefore, he did not believe that Zhao Bing was killed after only two days.

The Shuaifu army, which had been trained for months, was able to defeat Mongolia's Tanma Red Army with its small universe blast.

Of course, Zhao Bing is not crazy yet. He knows that it is a wall but still wants to hit it. His plan is to quickly use rockets to 'remotely' bomb the Chima Detective Army's barracks after entering Shuiguan. He has no intention of going up and getting close to them.

In his estimation, even if a 'meteor shower' cannot kill all the Tatars, it will definitely scare them. After all, this is the first time this thing has appeared in the world, and it is bound to cause panic and chaos. Then he will send

The infantry took the opportunity to board 6 and win in the chaos. This tactic of fishing in troubled waters was something I had become very good at.

However, considering that the accuracy of the rocket is "slightly poor", it is not possible to hit where you point it. Of course, the more concentrated the enemy troops are, the better the effect will be. If they disperse outside the military camp, the effect will be greatly reduced. Even if it can be done

For accurate sniping, he was reluctant to use a rocket to destroy an enemy. This time it was indeed not due to cost considerations, but because the craftsmanship bureau tried its best and only made more than 200 rockets, and there was no guarantee that all of them would work.

Therefore, whether the sneak attack on Shuiguan can be successful is related to the outcome of the battle, and thus affects the progress of the entire battle.

Everyone can see from the plan that this is a pot of unpalatable rice. Once the Red Horse Detective Army is alerted and the rocket attack is ineffective, Zhao Bing can only order the withdrawal of troops and return empty-handed, or attack by force at any cost and exchange for victory with human lives.

But after the patrol boat led by Pei Jing was captured, Zhao Bing saw the Guangzhou city gate open to him again, so he coaxed and threatened him into agreeing to falsely open the water gate, so that he could attack the city without any bloodshed and attack the still-unprecedented city.

The sleeping Tatar opened fire calmly.

But Zhao Bing knows very well that you can't put all your eggs in one basket. The battlefield is changing rapidly, and there are only things you can't expect, but not everything you expect. If Pei Jing rebels again before the battle, or is discovered by the defenders, he will still adopt the following methods.
