With the Liu family's own shipbuilding strength and the labor that Dazhu can recruit, the number of shipbuilders can reach tens of thousands. Gongsun Xiu wanted a huge warship, which cannot be careless. It is the capital to rampant the world in the future. He told Liu Zhi: "The best materials must be used, but you must not fool them. If you find that you cut corners, you will never give up."

Liu Zhi hurriedly said, "Don't worry, the materials you take are all of the best. There are some considerations about what wood you use for the masts and what wood you use for the decks."

Gongsun Xiu smiled and said, "This is the best, can the wood be fully prepared?"

This question is difficult. The ships built by the king are all first-class large ships. It is extremely difficult to get enough wood. Liu Zhi smiled bitterly and said, "The wood currently stored can only be built twenty large ships needed by the king."

Gongsun Xiu was stunned: "So few? Isn't it better to order the soldiers to cut down more trees?"

Liu Zhi was speechless, wiped the sweat from his forehead and smiled bitterly: "The trees that have just been cut back cannot be used. They need to dry the shade and remove the moisture from the boat trees before they can be used."

Gongsun Xiu thought that there was another process in the middle, so he said, "So that's it, then go over and take a look."

The group came to the huge yin dry farm and built a vast area of ​​yard full of various kinds of wood. As soon as he entered the yard, he felt cool and comfortable. This warehouse where wood storage seemed ordinary, but in fact it had multiple vents, with air flowing from all directions, but there was no sunlight.

Gongsun Xiu touched the wood, which had a layer of lime powder on it, and couldn't help but look at him suspiciously.

Liu Zhi explained: "The boat wood should be dried in the shade, placed in a cool and ventilated place, or placed flat, suspended, and then sprinkled with quicklime, which can kill insects and absorb water. In this way, the boat wood has no moisture and can be used to build a ship after seven or eight years."

He was surprised to hear that it would take seven or eight years for the boat wood to dry out, and said in surprise: "For such a long time, it took nearly ten years for the boat wood to dry out completely and rebuild it into a sea boat?"

Liu Zhi nodded with a wry smile: "Yes, King. This craft is unhurried. The king built large sea ships. First, the Liu family's stock of wood is insufficient, and second, there is no call from the government, and he dare not build too large sea ships. After all..."

He did not say anything later, and Gongsun Xiu also understood that without the government's call for privately depositing large sea ships, the crime was enough to be calculated as treason.

Gongsun Xiu was speechless when he heard this. He finally got several years of rest and wanted to build a boat. Since it took ten years to go, the daylily was cold and frowned and said, "After such a long time, the sea boat was not built. Tian Yu has led the navy to capture the coastal belt."

Liu Zhi suddenly looked panicked: "This - what should I do? Does Tian Yu really want to attack Liaodong?"

"I just made an example, and did not say that Tian Yu would attack Liaodong. Taiping only lasted five or six years at most. If I could not build a sea ship, with the strong troops of Wei, Liaodong would not be able to resist it at all. If it weren't for the dangerous road of the sea, Dazhu would even be directly captured."

Gongsun Xiu was also a little bored. He couldn't build a ship, so it took ten years to prepare a ship and a shipbuilding. How could he fight this battle?

I don't have a system!

He had a dark face and said nothing. Liu Zhi was trembling, fearing that he would anger King Yan, and whispered: "Forgive the villain to be incompetent, and cannot share the worries of the king."

Gongsun Xiu pondered for a little while and suddenly asked, "What would happen if he didn't do the Yin drying and used it directly for shipbuilding?"

"If you don't dry the shade, the boat will be built directly, and it will rot in less than a year and it will not be used at all."

Liu Zhi smiled bitterly, and had already calculated that the King of Yan would ask such a question, and replied: "The moisture contained in the boat wood must be about 20% of the water before the ship can be built."

Gongsun Xiu thought about how to get this moisture out, which was a big problem. He frowned and said, "I have something unknown. If I don't use the shady drying, but instead burn it in the sun, what's the effect?"

Liu Zhi shook his head, "While exposing the sunlight can squeeze out moisture, the boat trees are easy to crack, which is not advisable. Over the years, the Liu family dock has been a hundred years of trees, drying in the shade for eight years, and building ships in one year."

The tree grows for a hundred years and is cut into a ship. It takes seven or eight years to dry the ship. After all the drying is completed, the curve of the ship is fixed. Because the hull itself has curves, the ship is also fixed in order to mobilize the ship craftsmen and civilians to build a whole ship for a year.

This process is long. First, the quality of the shipbuilding directly affects the life of the ship. The main manifestation is that the wood is not fully dehydrated and dried, and it is easy for the ship to deform and decay, and it is more likely to rot when moored in the water all year round.

Building a large ship is expensive and can cost millions of dollars at any time. Of course, you cannot be hasty. If you don’t do it in the dark, you will build a ship without being sunk. If you are not sunk by the enemy, you will rot on the sea first.

Gongsun Xiu was silent for a moment, and suddenly thought of something and said, "Maybe you have ignored one thing, don't dry the shade or expose the sun. The former is too slow and the latter is too impatient. It is better to choose the fire-cured smoke method."

"Fire-cured smoke?"

These four words made Liu Zhi stunned. He had never heard of such a method of building a ship.

Thinking carefully, it seems like that.

This has never been tried such an absurd method. After all, traditional boat trees are dry naturally, and they have not been tried to roast them with smoke and fire.

At present, the only way to treat a dead horse as a living horse, and a dead tiger as a dead tiger pretends to be a brave man to beat him up. Whether it is effective or not is left to fate.

Gongsun Xiu didn't know his casual words, and accidentally used the British shipbuilding reform method in the 18th century, one was to use fire to cure smoke, and the other was to use the method of burying sand. The British in the 18th century used this method to reduce the natural shading that originally took seven or eight years to less than one year.

Liu Zhi was still confused and thought that King Yan was eager to build a ship, and he didn't know whether the method of roasting smoke and fire was effective. But if you think about it carefully, if you build an earthen kiln, burn the kiln to a temperature increase, dry the water of the boat wood and then shape it, this is a way.

As for whether it can be successful, it was proposed by the King of Yan as if it was born in a flash. If it was effective, everyone would be happy and he would be considered a meritorious minister. If it was ineffective, it would be the responsibility of the King of Yan alone.

He hurriedly said, "Yes, yes. The king, the villain immediately arranged for the craftsman to build a large kiln."
