After Lin Chuan sent the two masters away, he moved the idea of building a sea ship base.

However, Lin Chuan thought about it again and felt that the current sea ships were still not completely in line with his expectations.

So Lin Chuan planned to go to the system to see if he could draw the drawings of the sea ships he wanted from the system lottery.

【Ding! Congratulations on getting the ×1 microwave oven manufacturing blueprint! 】

【Ding! Congratulations on obtaining the F22 fighter building blueprint ×1! 】

......

【Ding! Congratulations on obtaining the treasure ship building blueprint ×!! 】

After a ten-in-a-row draw, Lin Chuan looked at the treasure ship manufacturing drawings in his hand and laughed excitedly.

"Hahaha, I didn't expect this character to explode, and I actually drew the blueprint of the treasure ship in ten consecutive draws!"

Although the F22 is even more invincible, even if Lin Chuan gives him an F22 now, he can't find anyone who can take off this big killer now.

If he can draw the treasure ship blueprint in ten consecutive draws at a time, Lin Chuan is already thankful.

Lin Chuan knew very well that the treasure ship was much more advanced than the current four-masted sailing ship, and he must know that Zheng He had completed the feat of going to the Western Ocean seven times on the treasure ship.

Among the seven voyages to the Western Ocean, Zheng He took the treasure ship as far as East Africa and the Red Sea, which shows that the advantage of the treasure ship in the ocean voyage is incomparable.

And Zheng He's voyage to the West can be said to be the largest in ancient China, with the largest number of ships and seafarers, and the longest sea voyage, and all thanks to the treasure ships.

After finally calming down his excitement, Lin Chuan carefully checked the treasure ship drawings he had just drawn from the system.

The treasure ship on the drawing is as tall as a building, with a wide bottom point, a high head and tail, a sharp tail and a guard plate on both sides, and the cabin is a watertight compartment structure.

And the tip of the bottom is conducive to breaking the waves, the draft is deep, the stability is good, safe and comfortable, it is the most advanced sea ship sailing in the South China Sea and the Western Ocean route, and it is also the largest wooden sailing ship in the ancient world.

Such advanced treasure ship manufacturing drawings are now in Lin Chuan's hands, as long as the treasure ship is successfully manufactured, then Great Wei will become a well-deserved maritime overlord 1,600 years in advance!

Early the next morning, Lin Chuan came to the R&D center again, and at the same time called the two masters who had experience in manufacturing sea ships.

In the R&D center, Chen Yuan, Master Fang and two masters, who were looking at the excited Lord Hanzhonghou, carefully took out a drawing from his arms.

Then the four of them gathered around the table and carefully examined the drawings in front of them.

Chen Yuan only knew that this drawing was a big ship, and the more Master Fang and the two masters looked at it, the more surprised they became.

"Lord Hanzhong, what kind of big ship is this?"

Master Fang couldn't help but ask Lin Chuan at first.

"Haha, the big ship on the drawing is called a treasure ship, and it is a real large sea ship!"

Lin Chuan explained with a smile to the other master.

The two masters, who had experience in building sea ships, kept their eyes on the drawings of the treasure ship and never took their eyes off for a moment.

After a quarter of an hour, the two masters finally removed their eyes from the treasure ship drawings and looked at each other, and they could see the excitement and shock in their eyes!

"Lord Hanzhong, where did you get the method of building this ship? The design of this treasure ship is truly amazing! ”

"Lord Hanzhong, if this treasure ship is made, the danger of sailing in the sea can be greatly reduced!"

The two masters said to Lin Chuan one after another, their tones were very excited and excited.

Although they had never seen what a real treasure ship looked like before, with the instinct of an old shipwright, it was easy to find out the advanced points of the treasure ship, and they were amazed by the idea of making the treasure ship.

"The manufacturing drawings of this treasure ship were also found by Ben Hou from the inheritance of his master, and then showed it to you to see if it could be used as a large sea ship."

In the face of this kind of problem, Lin Chuan naturally pushed it directly onto the inheritance of the master who saw the beginning and the end of the dragon.

Everyone's answer to Lin Chuan was the same as Lin Chuan's previous medical book, and there was no doubt after hearing the inheritance of the master.

That is the manufacturing method handed down by the immortal family, and mortals are lucky to be able to see it for life, and they have to dig into the root and ask what to do!

"Two masters, as well as Master Fang, look at how many craftsmen and materials are needed to make this treasure ship?"

Lin Chuan couldn't wait to make the treasure ship, and immediately asked the two masters and Master Fang.

"Returning to Lord Hou of Hanzhong, the two of them really couldn't judge for a while how many shipwrights and materials were needed to build this treasure ship.

However, the manufacture of seagoing ships is quite cumbersome, and it is still unknown whether the first treasure ship can sail on the sea normally after being launched.

And no one has ever really built a treasure ship before, so I can't give Lord Hanzhong Hou a prepared answer. ”

The older master directly poured a basin of cold water on Lin Chuan, this treasure ship is not like a Shenwei cannon, it can be built in a few days after having the drawings.

Lin Chuan finally calmed down when he heard this, knowing that it was not an easy task to build a treasure ship, even if he had drawings.

Then the two masters popularized the way of building a big ship to Lin Chuan.

The shipbuilding method used by the current Great Wei is still a relatively convenient slipway type, but this method is not suitable for making treasure ships in Lin Chuan's eyes.

So Lin Chuan popularized the method of dock-type shipbuilding to the two masters, and this shipbuilding method was also common in later generations.

Dock type, simply put, is to dig a big pit in the ground as a dock, and then build a ship inside, and then fill the dock with water after it is built, so that the ship can float up and sail out of the dock.

When the two masters and Fang heard the dock-type shipbuilding method proposed by Lin Chuan, they couldn't help but be shocked again.

After talking about the shipbuilding method, all that remains is the wood and craftsmanship required for shipbuilding.

Whether it is the selection of wood or the making of wood into planks and components that can be used for shipbuilding, it takes time and a lot of manpower and material resources.

Therefore, after listening to the explanations of the two masters, Lin Chuan found that if he really wanted to turn the treasure ship from a drawing into a real thing, it was not enough to rely on the ability of Hanzhong County.

The treasure ship is a large sea ship, which is equivalent to the aircraft carrier level in later generations, and it is difficult to manufacture it without using the power of the state and relying only on a county.

Lin Chuan also basically understood the difficulty of building a treasure ship at this time, so he decided to let Cao Cao take action and mobilize the strength of the entire Great Wei to manufacture the treasure ship.

However, Lin Chuan definitely can't directly say to Cao Cao that I built the treasure ship so that the Hanzhong Chamber of Commerce can have more raw materials and manufacture more goods to develop rapidly.

After returning to the study of the Hou Mansion, Lin Chuan began to think about how to get Cao Cao to strongly support him in the construction of treasure ships, and to be able to send a naval army to conduct maritime trade in the name of Great Wei.

After thinking about it carefully, Lin Chuan still decided to start with the silk of the Han Dynasty. Lu started and explained to Cao Cao the advantages of building treasure ships for ocean trade.

After making up his mind, Lin Chuan began to write a letter to Cao Cao.
