In this shipyard in Langya County, Li Yang was surprised and delighted to meet the people of the Gongyi family who were famous for their craftsmanship during the Spring and Autumn Period and the Warring States Period, and he was also the current head of the Gonglo.

Regarding the public loser, some people in later generations believed that the public loser was only Lu Ban, and then he was unknown.

Actually, this statement is wrong.

Because Lu Ban's family was originally a family of craftsmen, and his ancestors were very good at carpenter work, and the things they made were extremely ingenious.

Lu Ban was exposed to the knowledge of architecture and carpentry from an early age, coupled with his personal talent, so he made his achievements in craftsmanship.

Since Lu Ban himself is a family of carpenters, after him, the public loser will naturally inherit and carry forward the family's business.

Therefore, the public loser, since Lu Ban, has actually been proficient in the ability of institutions and craftsmen. It's just that Lu Ban's name is too big, and it is difficult for his descendants to surpass and overshadow Lu Ban's name.

Li Yang was very curious, the Gongyi family was a family of craftsmen and was famous all over the world, why didn't the government invite him over? After all, there are many craftsmen in the world, and almost all the skilled craftsmen have been recruited.

Thinking of this, Li Yang turned his head to He Zhang and asked, "He Zhang, you also know the public loss book in front of you, right?" ”

Unexpectedly, He Zhang smiled and said: "The dean doesn't know, I have known the public loss book many years ago. ”

"Oh?" At this moment, Li Yang felt a little surprised.

At this time, the public loss book took the initiative to explain: "Huizhen Guojun, the lower official also served in the general Shaofu many years ago, but His Majesty wants to build a sea ship and go to sea to find the elixir, so the lower official asked Ying to return to his hometown and take charge of shipbuilding." ”

"I see!"

As soon as he heard this, Li Yang suddenly realized.

The public loser is indeed a family of Lu Guo, that is, a native of Shandong.

It's just that what Li Yang didn't expect was that the original sea ship manufacturing industry in Daqin actually arose because Qin Shihuang wanted to go to sea to find immortal medicine.

Of course, Li Yang also roughly understood at this time why Daqin's sea ships could be so developed, and the reason for it may be directly related to the public loss book that led the manufacture of sea ships.

Li Yang has a lot of respect for the public loss book, which makes the public loss book feel a little empty.

This is not because of how big Li Yang's official position is, but because Li Yang's achievements in invention and creation are the first person today. And his own skill of machine craftsmanship, compared with Li Yang, is not worth mentioning at all.

Think of the paper-making, the printing, the saddle, the stirrups, the gunpowder, which one did not shock the world, no one compared?

Therefore, in front of Li Yang, he didn't dare to pretend to be a loser.

Next, Li Yang entered the shipyard for a tour under the leadership of the public loss book.

The shipyard occupies a large area and is divided into two parts, indoor and outdoor, with the indoor for component processing and the outdoor for the whole ship assembly.

Daqin's manufacturing industry is so developed that even shipbuilding is an assembly line operation, divided into different workshops, which is simply awesome.

At this time, the sea ships were naturally pure wooden ships.

In addition, the public loser is also a carpenter family, perhaps this is also the reason why Qin Shi Huang arranged for the public loser to serve as the capital of the Sea Ship Manufacturing Bureau.

I saw that in the shipyard, hundreds of carpenters were seriously busy with various wooden components of the hull.

The head of the public loss book is Tao on the side, and he is still full of confidence and pride in carpentry and shipbuilding.

Walking out of the carpenter's workshop, there is a wharf in front of you, and countless craftsmen on the edge of the wharf are assembling the finished hull components into a ship.

A huge 30-meter-long sea ship, which was almost assembled, was docked at the shore of the pier.

This ship is probably close to 100 tons.

It's just that, after a detailed understanding, Li Yang found that the sea ship at this time was still a flat-bottomed hard sailing ship.

The biggest flaw of a flat-bottomed hard sailing ship is that the flat-bottomed center of gravity is unstable in a place with large waves; And hard sails, in places where the waves are high and the wind is strong, are even worse. Therefore, a flat-bottomed schooner is more suitable for rivers than oceans.

As soon as Li Yang saw this kind of flat-bottomed hard sailing boat, he immediately pointed out its shortcomings, which made everyone extremely surprised.

In particular, he was surprised and asked, "How does the dean know so much about this kind of sea vessel?" ”

Li Yang smiled: "This is all what Xu Fu told me." ”

Everyone suddenly realized.

There's no way, it's impossible to say, Lao Tzu crossed over, right?

The public lost the book and said: "The dean does not know, the wind and waves at sea are extremely large, and the wind and waves of non-rivers are comparable, so when sailing on the sea, the wind and waves are urgent, and the center of gravity will be unstable. ”

Li Yang said: "Then have you ever thought that you can change the flat bottom to a pointed bottom?" ”

"Change the bottom of the boat to a pointed bottom?" The public lost the book for a moment, and his brows furrowed.

Li Yang said: "That's right, if the bottom of the ship is made into a pointed bottom, then there are more underwater parts, so that the hull under the waterline is increased, and the center of gravity is moved down to the waterline, the lower the center of gravity, the more stable the ship will be, and the stronger the ability to resist wind and waves, which is extremely suitable for ocean navigation." ”

Hearing this, the public loser's eyes lit up, and he suddenly exclaimed: "Yes, why didn't I think that I could increase the center of gravity underwater." ”

Speaking of this, the public lost book looked at Li Yang in surprise, he had really seen Li Yang's ability now, and immediately said with admiration: "The dean really has the wisdom of the heavens, with a peerless knowledge, and outstanding wisdom, he can improve the sea ship in great strides casually, which is really amazing, and the lower officials are really admired!" ”

The public loss book is not a sycophant, he was really stunned by Li Yang's words.

In the past few years, I have been thinking hard about how to make the sea ship more stable, but I have never thought of a good way, and the result is ...... The Zhenguo Monarch in front of him actually thought of a way to improve it just by looking at it, how could this not be shocking.

Of course, He Zhang and others were also extremely surprised.

Although Li Yang has already invented papermaking, printing, gunpowder and other gods, his intelligence is known to everyone, but they did not expect that he would even be so good at building ships, this is simply an all-rounder.

At that moment, Governor Ren Bu took a deep look and said: "The talent of the dean is really rare in the world, from ancient times to the present, no one can compare." ”

Li Yang smiled, but he was extremely modest: "You don't have to praise, this gentleman is just a casual little opinion, it's not worth mentioning." ”

As the current head of the Gongyi family, who is known as the world's first skilled craftsman, he felt like crying when he heard this.

The problem that I can't solve for many years can only be regarded as a small opinion in the mouth of others......

God, why is the gap between people so big?

In terms of craftsmanship, I have always been proud and arrogant, and today I felt for the first time what is inferiority and what is called hanging in your professional field.

Originally, in the shipbuilding industry, he regarded himself as an "expert", but at this time, he immediately took a "student" posture and humbly asked for advice: "The dean is a great talent, I don't know what other ideas I have for sea ships, and I hope to give more advice." ”

He is really humbly asking for advice, and if he can get more ideas and opinions on improving the seagoing vessel, it will be a great gain.

It's just that at the same time, he also feels in his heart that Li Yang is not a person engaged in shipbuilding after all, and now he can suddenly think of changing the flat bottom to a pointed bottom, increasing the hull below the water level, and improving the stability of the sea ship, which is already extremely unexpected. If there is any other way to improve it, it is obviously unlikely.

Li Yang said: "Benjun does have some ideas about sea ships, such as this hard sail, which can actually be improved. ”

"How can the sails be improved?" The public loser is really stunned, how can this person really have other ideas?

Li Yang said: "There is only one support point for the hard sail, so the area of the sail is limited, and the extensive use of wooden skeleton also limits its draft, so the speed is very slow, and the efficiency is low when sailing across the ocean, which is not suitable for ocean sailing." Moreover, the hard sail can only be raised to the top, and the sail power cannot be adjusted according to the situation, which is not good for crossing the islands. Therefore, this gentleman thinks that it is changed to a soft sail. ”

Then, Li Yang began to talk about what the soft sailing ship looked like.

Finally, he concluded: "The soft sail can be larger because of the large wind and many support points, and the speed and load are greatly advantageous, and even if the soft sail on the same mast is one section at a time, the sail force can be adjusted according to the situation, which has the advantage of being good for naval battles and avoiding reefs, and also for safe slow driving in case of smaller storms." ”

“…………”

The public loser was directly stupid, his mouth was shocked into an "O" shape, and the whole person was messy!

He suddenly discovered that Li Yang actually knew how to build a ship better than himself!
