Daqin started with offering immortal medicine

Because Lu Ban's family was originally a family of craftsmen, and his grandparents were very good at carpentry, and the things they made were all ingenious.

Lu Ban has acquired knowledge about architecture and carpentry since he was a child, coupled with his personal talent, this is why he has achieved his achievements in craftsmanship.

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

Therefore, the public loser, since Lu Ban, has actually been proficient in mechanism and craftsmanship.It's just that Lu Ban's reputation is too great, and it is difficult for future generations to surpass and overshadow Lu Ban's reputation.

Li Yang is very curious, the Gongshu family is a family of craftsmen and well-known in the world, why didn't the general government invite him over?After all, there are many craftsmen from all over the world in Jiangzuo's mansion, 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 only knew about this public transport book in front of you today, right?"

Unexpectedly, He Zhang smiled and said: "The dean doesn't know, but Gong Shuji and I have known each other many years ago."

"Oh?" This time, Li Yang felt a little surprised.

At this time, Gong Shuji took the initiative to explain: "Mr. Huizhen, the lower official also served in Jiangzuo Shaofu many years ago, but His Majesty wants to build a sea-going ship and go to sea to find immortal medicine, so the lower official invited Ying to return to his hometown and take charge of the shipbuilding. thing."

"I see!"

Hearing this, Li Yang suddenly realized.

The public loser is indeed a Lu family, that is, from Shandong.

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

Of course, Li Yang also roughly understood at this time that why Daqin's sea-going ships can be so developed, the reason may be inextricably and directly related to the Gongshu Chu who led the sea-going ship manufacturing.

Li Yang respected Gong Shuchu very much, which made Gong Shuchu feel a little guilty.

This is not because of Li Yang's official position, but because of Li Yang's achievements in inventions and creations, he is the No. 1 in the world today.But compared with Li Yang's, his own crafting skills are not worth mentioning at all.

Think about papermaking, printing, saddles, stirrups, and gunpowder. Which one is not shocking and incomparable to the world?

Therefore, in front of Li Yang, Gongshu Chu didn't dare to pretend at all.

Next, Li Yang, led by Gongshu Ce, entered the shipyard for a tour.

The shipyard occupies a huge area and is divided into indoor and outdoor parts. The indoor part is for component processing, and the outdoor part is for the assembly of the whole ship.

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

The sea boats at this time are naturally pure wooden boats.

In addition, the public loser is also a family of carpenters. Perhaps this is why Qin Shihuang arranged for the public loser to serve as the post of Du Zuocheng in the Shipbuilding Bureau.

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

Gongshu Ce explained in a straightforward manner. He was still full of confidence and pride in carpentry and shipbuilding.

When walking out of the carpentry workshop, there is a pier in front of it. Countless craftsmen beside the pier are assembling the finished hull components into a ship.

A 30-meter-long huge sea ship, which has almost been assembled, is currently docked on the shore of the pier.

This ship is probably close to a hundred tons.

However, after detailed understanding, Li Yang discovered that the sea ship at this time was still a flat-bottomed hard sailing ship.

The biggest defect of a flat-bottomed sailboat is that the center of gravity is not stable when the flat bottom is in a place with strong waves; and the hard sail is not good in places where the waves are high and the wind is strong.Therefore, flat-bottomed hard sailing boats are more suitable for rivers than for oceans.

As soon as Li Yang saw this flat-bottomed sailboat, he immediately pointed out its shortcomings, which surprised everyone.

Especially Gongshu Chu, who was very surprised and asked, "How does the dean know so much about this kind of sea-going ship?"

Li Yang smiled and said, "Xu Fu told me all of this."

Everyone suddenly realized.

There's no way, it's impossible to say, Lao Tzu has time-traveled, right?

Gongshu Chu said: "The principal doesn't know that the sea is extremely windy and waves, not comparable to the wind and waves of a river. Therefore, when sailing on the sea, the wind is high and the waves are rough, and the center of gravity will be unstable."

Li Yang said: "Then have you ever thought about changing the flat bottom to a pointed bottom?"

"Change the bottom of the boat to a pointed one?" Gongshu Chu was taken aback, his brows furrowed.

Li Yangdao: "That's right, if the bottom of the ship is made into a sharp bottom, then there will be more underwater parts, so that the hull below the waterline will be increased, and the center of gravity will be moved below the waterline. The lower the center of gravity, the more stable the ship will naturally be." , the stronger the ability to resist wind and waves, it is extremely suitable for ocean navigation."

Hearing this, Gong Shuchu's eyes lit up, and he said in surprise, "That's right, why didn't I think that I could increase the center of gravity underwater."

Speaking of this, Gongshu Chu 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 sky, possesses the world's unique knowledge, and is extremely wise. , To be able to make great strides to improve the sea-going ship casually is truly astonishing, and the lower officials are really amazed!"

Gongshu Chu was not flattering, he was really stunned by Li Yang's words.

For the past few years, I have been thinking hard on how to make the ship more stable, but I have never thought of a good way. As a result... the Lord Zhen in front of me actually thought of a way to improve it just by looking at it , how is this not shocking.

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

Although Li Yang has invented papermaking, printing, gunpowder and other fetishes, everyone knows his intellect, but no one would have thought that he would be so good at building ships. Only.

At that moment, Governor Ren Bu bowed deeply 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 humble: "You don't need to praise me, I'm just making some random comments, it's not worth mentioning."

As the current head of the Gongshu family, Gongshu Chu, who is known as the most skilled craftsman in the world, felt like crying when he heard this.

The problem that I have not been able to solve for many years, in the mouth of others, can only be regarded as a small opinion...

God, why is the gap between people so big?

In terms of craftsmanship, Gongshu Chu, who has always been proud and arrogant, felt for the first time today what it means to be inferior and what it means to be beaten in your professional field.

Gongshu Chu, who originally regarded himself as an "expert" in the shipbuilding industry, immediately took the attitude of a "student" and humbly asked for advice: "The dean is a talented person, I don't know what else he thinks about sea-going ships, I hope you can give me more advice. "

He is really asking for advice with an open mind. If he can get more ideas and opinions on improving sea-going ships, that would be a great harvest.

However, at the same time, he felt in his heart that Li Yang was not a shipbuilder after all. Now that he had a sudden idea, he thought of changing the flat bottom to a pointed bottom, increasing the hull below the water level, and improving the stability of the seagoing ship. It was already an extreme surprise.If there is another way to improve it, it is obviously impossible.

Li Yangdao: "I do have some ideas about sea-going ships. For example, this hard sail can actually be improved."

"How to improve the sail?" Gong Shuchu was really stunned. How could this person really have other ideas?

Li Yangdao: "There is only one support point for a hard sail, so the area of ​​the sail is limited, and the extensive use of wooden frames also limits its ability to absorb the wind, so the speed is very slow, and the efficiency of cross-ocean sailing is low, so it is not suitable for ocean sailing. Moreover, the hard sail can only Once it reaches the top, the sail cannot be adjusted according to the situation, which is not good for crossing the islands. Therefore, I think it should be changed to a soft sail."

Then, Li Yang began to boast, talking about what the soft sail boat looks like.

In the end, it concluded: "Soft sails have strong wind and many support points, so the area can be larger, and the speed and load have great advantages. In addition, even if the soft sails on the same mast are section by section, you can adjust them according to the situation. The advantage of adjusting the sail force is that it is conducive to sea battles and avoiding rocks, and the second is that it can travel safely and slowly in case of minor storms.”
