Chapter 130 Copper Skin

The medical officer diagnosed Yu Xiaotian's pulse every day, constantly adjusted his diet, and used food therapy and soup to recuperate his body.

And Lan'er and Xiu'er tried their best to make delicious food for Yu Xiaotian every day, and Yu Xiaotian gradually recovered.

With Yu Xiaotian's gradual recovery, the Sea Wolf Group has once again stabilized.

For more than a month, the sea wolf is actually surging inside. Many people are worried about Yu Xiaotian's life. Some people inevitably begin to think about what they should do in case Yu Xiaotian's unpredictable death.

In fact, when Xiaotian was seriously injured, there were already a lot of ideas inside the sea wolf. Some people think that even if Yu Xiaotian let go, they would hold Xiaotian's son to the top and continue to work.

But Yu Zhenhua, Yu Xiaotian's son, is only half a year old now. It is not easy for people to grow up as a child in this era. If Yu Zhenhua is a little older, it would be easy to say about this matter. Now this little guy is still infuriating and breastfeeding. He wants to help him out to be a rudder. There is someone in this matter. Naturally, I am not very happy.

And if Yu Zhenhua is put to the top, he must be just a puppet, and it may only be others who are really in power. Naturally, it was Liu Laoliu who put forward this idea. Liu Laoliu is Yu Xiaotian's father-in-law, Yu Zhenhua's grandfather, and the head of the prison hall. Once Yu Xiaotian is unexpected Naturally, the power will fall into the hands of Liu Laoliu.

However, some people are naturally not convinced that Liu Laoliu came to take power, because although Liu Laoliu is a good person, he also tries his best to be the head of the prison hall, and a bowl of water is also flat and very popular. However, after all, Liu Laoliu is a little older, and his vision is not broad enough. He is too defensive. Under his leadership, the sea wolf Know where to go.

And some young strong factions are relatively ambitious. When they follow Yu Xiaotian, Yu Xiaotian oppresses them, and it can bring them a victory and a brighter and brighter future, so they work hard and feel at ease.

But once Yu Xiaotian is away, they will no longer feel at ease. They are not faithful at all, but they are selfish animals. When a group of problems, it is natural for people to have their own aspirations. These people don't want to listen to Liu Laoliu's arrangements and Ordered.

Therefore, during the period of Xiaotian's serious injury, various sounds and undercurrents appeared inside the waves, which is also inevitable, but all these undercurrents, as Yu Xiaotian gradually emerged from the danger period and gradually began to recover, suddenly disappeared, because as the soul figure of the sea wolf, he returned to power. After the peak, everyone automatically returned to the original track.

When Yu Xiaotian was recovering, he also learned these things from Liu Laoliu, but he laughed it off and did not pursue anyone, let alone expand the matter.

As him, of course, I hope to pass something on to his children behind him, but at present, Zhenhua and Yuxin (the daughter of Xiuer, named Yuxin by Yu Xiaotian) are still young. His big plate is obviously not what he wants to pass on to Zhenhua.

It is impossible for Zhenhua to take over such a big plate at such a young age. The power will naturally fall into Liu Laoliu's hands. Although Zhenhua is Liu Laoliu's grandson, he is selfish. With Liu Wang, sooner or later Liu Laoliu will take Power was transferred to Liu Wang, and Xiao Zhenhua was at best a puppet pawn in Liu Laoliu's hands. In the future, once Liu Laoliu wants to hand over power to Liu Wang, Xiao Zhenhua will become a dangerous person.

At that time, the family affection may disappear, and eventually there may even be killing each other between father, son, brothers, uncles and nephews like the royal family.

So in Xiaotian's opinion, if one day he suddenly encounters something wrong, it would be better for Lan'er and Xiuer to take Zhenhua and Yuxin to move far away and live an undisputed life than as a puppet here.

And as the soul of this group, with him, the sea wolf is the real sea wolf. If something unfortunate happens to him, then he will not bother to care about the affairs behind him. People have their own aspirations. In the future, these people can do whatever they want. What he wants is to have absolutes to this group when he is alive. Control makes the group work for him according to his ideals.

At present, he is quite satisfied with the current situation! At least, his status as a sea wolf is unshakable. In this era, if he wants to do something, he has no absolute control over his own power, which is similar to suicide. Now if he talks about bullshit democracy, unless his head is kicked by a donkey!

After Xiaotian gradually recovered, he began to deal with the affairs of the sea wolf again. During his injury, many things of the sea wolf stagnated, but many of the things he had arranged before were still in progress normally.

First of all, during his serious injury, the Chucai old Dafu ship that was transformed in the Nanri Island ship has now been completed. The ship basically met Yu Xiaotian's initial concept of transformation. A gun compartment was opened on the lower level, which greatly improved the ship's artillery carrying capacity and made it a sea wolf's current firepower. The strongest gunboat.

Moreover, the ship has improved the rudder operation mechanism and changed the previous steering rod operation mode to the steering wheel operation mode, which greatly improves the flexibility of the ship and makes the operation much simpler.

In addition, some changes have also been made to the sail installation, replacing the previous heavy lifting mechanism of the rudder with a pulley group, which made it much more labor-saving to lift the sail. In the past, it took five or six people to lift a sail, and at least three people to pull the wooden winch to complete the lifting of the sail. Now only two people are needed. Even in an emergency, a person can raise the sail, including a manual winch, which has been improved and installed the edict wheel structure.

When the sail had to fall urgently, it used to cut off the sail cord with a knife and axe, and the sail fell from the mast. It was fast, but when you want to lift the sail again, it was a big trouble. You had to send someone to climb up the mast, pick up the sail cord, and rearrange the sail cord, but it has been improved. After the winch, you only need to knock on the edict wheel, and the sail can be lowered equally quickly without affecting the sail cable. When you need to raise the sail, you only need to reset the edict wheel and pull the winch again to easily start the sail.

Moreover, the age of this ship is still short and can be used for a long time, but the problem of long-term seawater immersion, the erosion of the hull and the attachment of marine organisms to the bottom of the ship will seriously affect the service life of the ship, and may even cause the disintegration of the ship at sea.

Therefore, after thinking about it, Yu Xiaotian decided to cover the bottom waterline of the ship with a layer of copper. At present, this problem is a headache in navies around the world, including merchant ships, and people have also thought of many ways to solve this problem.

Some places coat the bottom of the ship with wood tar or soak the ship board with poison, but it cannot be effectively solved. The most effective way is to soak the ship into the freshwater river for some days, but it is very troublesome to do so, and sometimes the sea ship has to move at sea for a long time and has no chance to enter. In freshwater rivers, these methods are not very useful.

Later, the British came up with a way to cover all their warships with a layer of copper skin at the bottom of the ship, which solved the problem of maggots and eroding the ship plate, but the cost is a little too high. After all, copper is a precious metal in this era, including later generations, and it is hard to be directly circulated. The currency that covers the bottom of the ship consumes a lot of copper, and ordinary people really can't afford it.

But for sea wolves, it is not a big problem to wrap only a few boats, because sea wolves now basically use cast iron, so in recent years, a large number of purchases have been seized through * and a lot of copper materials have been stored.

These copper materials have been re-refined, and the Japanese red copper purchased through various means has a considerable amount of silver. After refining, the silver is extracted. In addition to obtaining copper, a lot of silver has also been obtained. Copper, as a strategic reserve, is naturally stored in large quantities. Now, it is enough to cover part of the bottom of the ship, so when the ship was towed into the dock, copper skin began to be made on the other side.

Copper skin is mainly used to prevent sea maggots and sea creatures. In fact, it can't be too thick. It only needs a thin layer, so the thinner the copper skin, the better.

If it is close to the manual copper plate, it is obviously a big waste. After all, the hand-made copper plate is too thick. In addition to a large waste of raw materials, it also adds a lot of dead weight to the ship.

Therefore, Yu Xiaotian did not intend to let all be manually to make copper plates, but decided to get a simple trigger to specially roll copper skin, so that the rolled copper skin is uniform in thickness and can be made thinner, which can save a lot of copper materials and reduce the weight of the ship.

But now a rolling mill is still a little too difficult for the sea wolf industry. The roller must be hard. When there is no high carbon steel, it can only be cast with cast with cast iron. The casting problem is not too big. The key is still in the transmission mechanism, especially gear manufacturing.

Gears don't look simple, but actually have a high technical content. With the current sea wolf's technology, if they want to produce sufficiently strong gears, for the time being, whether it is the machining ability or the technical ability of workers, including materials, it is very difficult to solve.

Finally, I brainstormed and thought a lot of ways, and finally decided to make it with extremely hard iron wood, but it can't be called a gear, but a transmission mechanism similar to a water mill.
