Gongsun Xiu had never seen a shipbuilding before, so he watched it from the side.

Liu Chuan had seen shipbuilding thousands of times. If he could see himself, he naturally knew the shipbuilding industry. He was by his side and explained the secrets of shipbuilding to him.

Liu Chuan laughed and said, "Your Majesty, this boat can only be considered a small boat for transportation. It really can't take too many people, but merchants on both sides of the Taiwan Strait take this boat to communicate with each other."

He nodded and frowned and said, "If this boat encounters wind and waves, can it hold on?"

Liu Chuan wiped the sweat from his forehead and smiled bitterly: "This - if the wind and waves are turbulent, or it is raining, it is not recommended to go to sea. Generally, traveling will roughly estimate the weather. Wait until the wind and waves are gradually flat before choosing to go to sea. People will also choose to burn incense and sacrifice to the sky, throw wine and meat into the sea, praying for the sea god to see you and travel safely."

Gongsun Xiu couldn't help but frown when he heard this. In other words, whether he could land on a boat during the Three Kingdoms period was basically a chance. He was superstitious about sacrifices like the sea god, and some even threw boys and girls into the sea.

"Romance of the Three Kingdoms" describes the Shu army's front army crossing the Lu River. Suddenly, the clouds were covered with clouds and the ship could not cross. The front army came back to report to Zhuge Liang to know. Zhuge Liang asked Meng Huo the reason, and Meng Huo claimed that there were rampant gods in the water doing evil, and he wanted to "use 7,749 heads and black cows and a white sheep to sacrifice them, so that the wind and waves were quiet, and the harvest was abundant year after year."

Zhuge Liang was not willing to kill people and throw them into Lushui to suppress Changshen, so he "knead as a agent", then "shape it into a human head", throw it into water, and replace the living person with the shape of a human head made of flour. Later, he indirectly invented steamed buns, which are pronounced as "mantou".

I don’t know whether the story is true or not, but the steamed buns were indeed invented by Zhuge Liang, and a small number of people in the area of ​​Shuzhong have begun to eat steamed buns.

In a ship that does not have the ability to sail far, life and death are all based on luck, which is naturally undesirable. If you want to rush across the Bohai Sea in the future, you must build a stable large ship that can ride the wind and waves and run rampant without any obstacles.

Although the coastline of the entire Bohai Circle is 8,000 miles, the narrowest part is from Dazhu to Donglai County in Qingzhou, which is only less than 200 miles. However, the Bohai Sea is about 700 miles wide from east to west, and the south to north is about 1,100 miles long.

If China map is compared to a rooster, then the Bohai Sea is located at the neck of the chicken.

And his goal is to chop off the whole chicken head with one knife and take it for himself.

If you want to take possession of the Bohai Sea, you must conquer the Qingzhou coast on the other side of Dazhu.

On the other side, Tian Yu Zhengtong led the Wei navy to guard Qingzhou.

In the sixth year of Taihe, Gongsun Yuan established a maritime transportation line to go south and contacted Sun Quan. Tian Yu also tried to cut it off. Zhou He, the envoy of Wu State, took a large ship from Dongwu to Liaodong to visit Gongsun Yuan. Tian Yu did not directly send troops to attack, but determined that Zhou He would encounter strong winds and waves when he returned to Dongwu. There was no mountain to support him in the east, so he would definitely reach Chengshan.

There is no place to hide ships in Chengshan, so I have to move around the shore.

Tian Yu observed the terrain and sent troops to lie on various dangerous places on the mountain island. Zhou He was indeed stormy when he returned to the voyage. The ship sank from the mountain. The surviving remaining ship floated to the shore and had nowhere to escape. He sent troops to capture a large area directly.

As the navigation capacity grew stronger, the Bohai Strait became a channel for war and a decisive battle platform for maritime military forces. There was a state of military confrontation between Qingzhou and Liaodong. The regime that entered Qingzhou would always expand the war to the sea, resulting in large-scale maritime military operations.

Gongsun Xiu looked at the shipbuilding side and suddenly discovered the clues and exclaimed: "So that's it."

The bottom of the shipbuilder built by the shipbuilding ship was almost vertical and flat, and the bottom was square, and the face suddenly showed a look of sorrow.

When Liu Chuan saw that the face of King Yan changed, he couldn't help but ask: "Master, what's wrong with you? But what's wrong with the shipbuilding?"

Gongsun Xiu frowned and said, "Why don't you add keels to build a ship?"

"keel?"

Liu Chuan had never heard of this novel name, and couldn't help scratching the back of his head and asked in confusion: "Your Majesty, the villain is stupid and does not understand what a dragon bone is--"

Gongsun Xiu thought that as a shipbuilder in Qingzhou, Liu family, didn't even understand what the keel was. I guess the shipbuilding technology of the Three Kingdoms period did not have the concept of designing the keel.

He thought to himself that this might be the key to defeating the two countries of Wei and Wu. The flat-bottomed boats are not well drawn. Whenever the wind is strong and the waves are high, it is easy to overturn the entire boat because of the head heavy and the feet are light. The bottom of the boat is different. The hull is thin and pointed on both sides, the bottom is V-shaped, and it floats deeper in the water, which also has a stable effect.

Gongsun Xiu pondered: "Your ship does not make dragon bones, and you will overturn every time you encounter wind and waves, and you will not draw deep water."

Liu Chuan said "Ah", but he still didn't understand what the dragon bone was, so he just asked: "I beg the king to teach you."

He knew that no matter how strong a ship was, even if an aircraft carrier weighing 70,000 ton in later generations encountered bad weather, such as typhoons and tsunamis, it would need to temporarily enter the safe haven. The word "loosening" was not a joke, and it was really possible that the giant monster-like aircraft carrier would be overturned.

But the ships of this era do not have keels, nor do they have compass and star-pulling boards, and they do not have the ability to sail far away and cannot sail directly from the coastline.

As long as the three major problems are improved, namely the keel, the compass, and the star-pulling board, the warship can be upgraded to several levels and truly overtake on the curve.

Gongsun Xiu looked at Liu Chuan and said lightly: "I have thought of how to create a top-notch ship in the world. Your Liu family's shipbuilding technology is rough and it is difficult to use."

Liu Chuan was stunned. As a century-old brand on both sides of Liaodong, the Liu Shipyard was denied by the king. It seemed to have more powerful skills. He couldn't help but be suspicious and said: "King, the villain must do whatever kind of ship you need."

As the largest shipyard in Liaodong, the Liu family had almost a slight advantage over the government shipyards. When Liu Yi was able to lead his troops and fightership to directly be promoted to Liaodong General by directly stating that his capital was evident.

He knew that the Liu family was surrounded by Dazhu and was a native of Qingzhou. If they were not used by themselves, they would be killed by themselves. If they went to Tian Yu on the other side one day, the losses of Yan State would be immeasurable, not to mention that his shipbuilding design concept was to surpass the technology controlled by Wei and Wu States.

Gongsun Xiu smiled indifferently: "The ship built by Gu wants to build a warship of the world, which is the most secret. Although Liu is in Yan State, it originated in Qingzhou, and is not an official in the court. If he uses secrets to join Wei State, wouldn't he be tied up in his own cocoon? Gu will build his own sea ship to protect the secrets in the future."

Liu Chuan was immediately embarrassed and thought to himself: "It turns out that what the king is worried about is this."

Since Liu Yi defeated Zhang Liao, the Liu family has not been an official for three generations and has only focused on building ships and production. The King of Yan was preparing to build large-scale sea ships, but he did not allow Liu family to participate. Naturally, he was worried that the Liu family would fall on both sides and that if they turned to Wei, all their efforts in Yan were in vain.
