After Lin Daxin returned to the Qing Dynasty, he handed over the process formula information of the alloy to Li Shaogang, the person in charge of the iron and steel plant.

Li Shaogang, the person in charge of the steel factory, was originally the owner of a small steel mill in Nanyang Malaysia, but because he offended the local British colonial rulers, the factory could not be opened, and after selling the steel factory to an Englishman at a low price, Li Shaogang fled back to China with his family.

Lin Daxin's cousin Wang Yan knew Li Shaogang, the two had dealt with each other before, Wang Yan knew Li Shaogang's ability, and when he learned about his situation, he arranged Li Shaogang to Lin Daxin's steel plant and became the person in charge of the steel plant.

After Lin Daxin chatted with Li Shaogang about the situation of the steel plant, he left the steel plant. Then Lin Daxin came to the shipyard not far from Weihaiwei Port and found Wei Han, the person in charge of the shipyard.

Wei Han was in the first phase of the Fuzhou Shipbuilding School, studying shipbuilding, and met Lin Daxin's father, Lin Yongsheng, during his studies in the school, and became friends.

After graduating in 1871, he was assigned to work at the Harbour Yard. In 1875, the director of the ship, the Frenchman Riyige, returned to France to purchase machine equipment, and Wei Han and three others went abroad to study. Wei Han, who excelled in learning, was rated as "bold and diligent" by Li Fengbao. After returning to China after completing his studies in 1879, Wei Han served as the chief shipbuilder of the Shipbuilding Engineering Department, which was equivalent to the chief engineer.

In December 1880, Wei Han was sent to Germany to supervise the construction of the Dingyuan ship.

After returning to China in 1882, he participated in the construction of the "Kaiji", and later presided over the construction of China's first steel-armored ship Pingyuan, during the shipyard period, Wei Han presided over or participated in the construction of "Kaiji", "Henghai", "Jingqing", "Huantai", "Guangjia", "Guangyi", "Guangbing", "Guanggeng", "Longwei", "Fujing", "Tongji", "Fu'an" and other 12 ships.

Wei Han was specially invited to Weihaiwei by Lin Daxin, and Wei Han also learned that Lin Daxin's shipyard would invest heavily in the construction of a batch of new warships, so Wei Han came from Fujian. As a designer and builder of warships, Wei Han has always wanted to design and build a more advanced warship, rather than a warship that some naval powers are about to obsolete.

However, because the Qing Dynasty did not invest much in shipyards, even the largest Fujian shipyard in the Qing Dynasty could only build some warships that were relatively backward compared to the West.

And Lin Daxin's shipyard is bad at everything, just not bad for money, plus Lin Daxin's father and Wei Han were classmates and friends of the Fujian Shipbuilding Academy back then, Wei Han agreed to come to Weihaiwei.

Lin Daxin handed over the design drawings of several suitcases of steam warships to Wei Han and said, "Uncle Wei, these are the design drawings of some British and German ships!" ”

Wei Han was taken aback when he heard this, quickly opened the suitcase, flipped through it roughly, and then said excitedly: "Pingshi! Where did you get these drawings from! These drawings are invaluable to our shipyard! According to these drawings, with a little modification, we can design our own warship! ”

Lin Daxin couldn't say that these drawings were shipped from the future time and space, so he made up nonsense and said: "These drawings were bought by me through some special channels!" And there are many of the drawings in it, which are also top secret in the UK and Germany! By the way, Uncle Wei, can our shipyard build warships now? ”

When Wei Han heard Lin Daxin mention the shipyard, he was shocked and said, "Pingshi! The equipment of your shipyard is really advanced! There are some that I haven't seen in any of the shipyards in the UK! Now the shipyard has produced more than 20 transport ships with a displacement of 700 tons, the workers already have experience in shipbuilding, and I am ready to start building a small protective cruiser, but now with these drawings, I refer to it and re-select a warship! ”

Lin Daxin said in his heart that of course the equipment is advanced, and many of the equipment in the shipyard are transported from modern time and space, and have the level of the 50s and 60s of the 20th century.

Lin Daxin looked at a pile of drawings and said, "Uncle Wei, I have handed over the formulas and processes of several new high-strength alloy steels to Li Shaogang of the steel factory!" In two days, new warship steel plates will be produced, boilers and steam engines for warships can also be produced in our machine factory, and naval guns on warships can be purchased from German Krupp through the German Lihe Foreign Company! Uncle Wei, can you see that we can produce these warships on the drawings now? It would be better to build all-steel battleships! ”

Wei Han smiled bitterly at Lin Daxin and shook his head, "Pingshi, although our current workers say that they have some experience in shipbuilding, they are still far from enough to build all-steel battleships, we can only start with small warships, so that the workers can accumulate experience in order to build larger warships!" ”

Lin Daxin was a little disappointed when he heard this, the design drawings of the steam warship that Lin Daxin brought over included the dreadnought-class battleship and the super dreadnought-class battleship, if he could build the dreadnought-class battleship and the super dreadnought-class battleship, he would be able to compete with the British Navy in this world!

Lin Daxin thought about it for a while and said to Wei Han: "Uncle Wei, the design drawings of the steam warship here, there is a new type of all-steel battleship, this kind of battleship adopts a unified main gun design, and the displacement of the warship is more than 20,000 tons. The design drawings of such a warship must be kept secret, this is a template for the future main battleship! The all-steel battleships built by the British now basically belong to the role of weak explosion in front of the battleships with unified main guns! ”

As soon as Wei Han heard this, he immediately began to study the drawings of the warship that Lin Daxin had brought over.

Lin Daxin instructed Wei Han that the design drawings of these steam warships must be kept secret and must not be seen by foreign technicians. Since his shipyard can't build large warships now, Lin Daxin doesn't want foreigners to know in advance about this brand-new battleship with a unified main gun.

Instead, let Britain and Germany continue to build pre-dreadnought-class battleships, consume the strength of these countries, and the more they build, the better, and as soon as the dreadnought-class battleships appear, all the pre-dreadnought-class battleships will be obsolete!

Wei Han patted his chest and promised Lin Daxin that Wei Han would not let the second person in the shipyard see the design drawings of these steam warships, and Wei Han would refer to the design drawings of these steam warships to design a warship that could be built in the shipyard.

Seeing that Wei Han, who had sunk into the design drawings of these steam warships, Lin Daxin, who couldn't help much, returned to the Sailor Academy first.

Early in the morning of the fourth day when Lin Daxin handed over Wei Han's drawings, Wei Han, who had dark circles under his eyes, came to Lin Daxin, "Pingshi, I have designed a fast protection cruiser with reference to the design drawings of those steam warships you brought over in the past few days, and our current shipyard can build it!" ”

Lin Daxin immediately took the design drawings brought by Wei Han and took a look.

With a displacement of 4,500 tons, a length of 110 meters, a width of 15 meters, and a draft of 6 meters, this Wei Han designed fast protection cruiser adopts 3 new steam engines, with 16 high-rise coal-fired boilers, two-shaft drive, and is designed to reach an astonishing speed of 24 knots and a maximum coal load of 750 tons.

This fast protection cruiser main gun uses 6 new naval guns of 210 mm 40 times caliber, and 8 155 mm 40 caliber rapid-fire guns are also designed on both sides as secondary guns, 20 57 mm rapid-fire guns, waterline armor 100 mm to 200 mm, deck armor, 50 mm to 100 mm, main gun turret armor 200 mm, secondary gun turret armor 100 mm, and conning tower armor 200 mm.

4 500 mm torpedo tubes, as well as a sharp, blade-sharp ramming angle under water in the bow. The crew is about 400 people! Considering that the naval guns needed to be purchased from Germany, this fast protection cruiser cost about 1.5 million taels of silver.

Wei Han said: "This fast protection cruiser is a fast protection cruiser based on the design drawings, after my slight modification, the design, although the displacement has reached 4500 tons, but I believe that our shipyard should be able to build this warship!" ”

Lin Daxin was very satisfied with this fast protection cruiser, the firepower was not weak, and the speed was fast, Lin Daxin decided that the shipyard would produce this warship!

So Lin Daxin said: "Okay! Uncle Wei, our shipyard will build this fast protection cruiser! Uncle Wei, how many are you going to build together? ”

Wei Han thought about it and said: "In order to save money, I consider this warship to be the first warship built by our shipyard, and build one to test the water first!" If there is no problem with the construction of this warship, we will build a few more according to the needs of the navy! ”

When Lin Daxin heard that there was only 1 ship, he immediately felt that Wei Han was too petty, so he asked: "How many docks can our shipyard build this warship in now?" ”

Wei Han replied: "There are 8 docks of more than 5,000 tons that can build this fast protection cruiser with a displacement of 4,500 tons!" ”

"That's good! Uncle Wei, let's build 8 of these fast protection cruisers together, and ask for money for money and people for people! Is there a problem with Uncle Wei Shipyard? With a wave of his hand, Lin Daxin decided to build 8 ships together.

Wei Han looked at Lin Daxin dumbfounded, and finally knew what a local tyrant was! In the past, in the Fujian Shipyard, it was good to design a warship that could build 1, but now Lin Daxin asked Wei Han to build 8 ships together, which requires 12 million taels of silver!
