In the following days, for half a month, Zhu Jie spent more than ten days in Yingtian Academy, communicating with the scholars in the academy and helping them divide the departments.

The most important thing is to point out the research of everyone, especially the young students of the Ming Dynasty, have gradually opened their minds, in the difficulties of research, just need Zhu Jie a little bit of dialing, to be able to open up, real in-depth research, or how detailed the explanation, Zhu Jie does not have that ability, after all, he is just a special soldier, for machinery, for the science of the market only has a superficial cognition, know a context, let him do calculus now, he Zhu Jie does not have that ability, The things they learned in school have almost been forgotten, and they can only be guided by memory.

Even so, the achievements of these people are very impressive, especially the young people who admire Zhu Jie very much, and some have even been immersed in chemical research, Zhu Jie only puts the most basic principles of chemical research, such as quantification, such as analysis and derivation, and the rest is the young people's own business.

In just half a month, some of them have begun to study the science of combustion, and some people have proposed that not all air can support combustion, at least, in the residual gas after combustion, it is basically impossible to burn again, which shows that combustion consumes a part of the gas, which is the gas that supports combustion, and other gases cannot support combustion, and some people also propose that a ball of cotton burned cotton is thrown into a sealed container, and the cotton is burned. But the mass of the container has not changed, which means that after the cotton is burned, it becomes something else, to be precise, gas, because the residue of the cotton burning is significantly lighter than the cotton before the burning......

However, these are no longer Zhu Jie's concerns, Zhu Jie's responsibility is only to guide them in the right direction, and it doesn't matter how the rest goes, even if they run barefoot on the mountain road and their feet are blistering, it is the price that these people should bear, and it is impossible for you to achieve any achievements without paying the price.

Half a month later, Zhu Jie left Nanjing for Songjiang Mansion, stayed in the First Fleet for two days, and listened to the report of Admiral Yang Geng, the commander of the First Fleet, the strength of the First Fleet has now recovered to eighty percent of its original peak, with more than 80 Tian-class and earth-class main warships, and, in the past three years, according to Zhu Jie's suggestion, the battleship has been refitted, the number of naval guns has been reduced, and a certain number of rockets has been added, and the strong combat power of the battleship is still maintained, plus other warships, the number of warships has approached 200.

Speed, what Zhu Jie wants is speed, other places can cut back on food and clothing, but for the construction of the navy, he has never been stingy, and he allocates more than three million taels of silver to the two fleets every year, how can the speed of the development of the fleet slow down? In the past three years, more than 500 admirals have received Zhu Jie's training in turns, and compared with the previous ignorant admirals, the current admirals have significantly improved their tactics and technology.

Of course, Zhu Jie is still more at ease with the First Fleet, after all, they are all elite forces, and they have been baptized by the Dongying Naval Battle, and their combat power is strong.

Two days later, Zhu Jie took the battleship of the First Fleet and went south along the East China Sea to Fuzhou to patrol the Second Fleet!

The second fleet is the focus of the south of the Yangtze River, from the second fleet began to build, it has been more than four years now, Zhu Jie has not been to once, all the affairs are entrusted to Zheng Haotian and Zheng Cai, the two naval giants are not ambiguous, the second fleet is well organized, good news is frequent, four years, the second fleet has already formed a strong combat power, although compared with the first fleet, there is still a slight gap, but it is already about the same, especially Zheng Cai, in order to repay the emperor's kindness, day and night, In more than four years, at least 1,000 days and nights have been spent on battleships, and Zheng Cai has definitely contributed to the rapid development of the Second Fleet.

After traveling more than 2,000 miles by sea for two days and two nights, the battleship finally arrived at Mawei Harbor and came to Fuzhou.

Sun Chuanting, who got the news, had already led officials of all sizes to greet him at Mawei Harbor, Governor Sun Chuanting, Governor and Commander-in-Chief of Fuzhou Shu Xinchen, Admiral Zheng Haotian of the Second Fleet, and Admiral Zheng Cai, Commander of the Tongzhi Commander-in-Chief, all of whom were looking into the distance from the dock.

A huge battleship slowly sailed into the harbor, leaned on the dock, the battleship stopped, Zhu Jie jumped down along the sampan, and then Cha Xuan, Bi Dengfu and others only followed and jumped off the battleship, and even Yang Geng followed to Fuzhou.

"Ministers see the emperor, long live, long live, long live!"

Sun Chuanting and the others knelt on the ground and saluted Zhu Jie.

Zhu Jie laughed and said: "Okay, get up, Bai Gu, over the years, you have been sitting in Tiannan, but you have worked hard, everyone get up, Xinchen, you have lost a lot of weight, it is good to work state affairs, but you also have to pay attention to the ...... of your body"

Everyone got up one by one, and Sun Chuanting said respectfully: "Your Majesty, it's been a long journey, please go back to the palace to rest and rest for one night, tomorrow we will patrol the second fleet!" ”

Zhu Jie shook his head and said, "No need, Bai Gu, you still don't know about me?" Since we met in Henan, in the past ten years, I have spent half of my time in the war, how can I help me with such a small trip? Let's go, Haotian, Yu Gong, the two of you are the hosts today, lead me to have a good tour of the Second Fleet! ”

The two men hurriedly agreed, boarded the boat again, and came to the flagship of the Second Fleet.

"Your Majesty, this warship is the flagship of the Second Fleet that has just entered active service, it is even bigger than our heaven-class battleship, a giant battleship of 3,500 materials, even if it is placed in the fleet of the Western Ocean, it is also a giant battleship second to none!"

Zheng Haotian pointed to the warship and said to Zhu Jie: "This warship, equipped with a total of 10 heavy guns of 60 catties of solid shells, 50 flowering cannons, is extremely powerful, in addition to heavy artillery and flowering cannons, there are also 20 sets of rocket launchers on the deck, in combat readiness, keep 3,000 rounds of flowering shells, 1,000 rounds of solid bullets, 600 rounds of rockets, actual combat power, even stronger than the Tian-class battleship!" ”

A giant battleship of 3,500 materials, according to the weights and measures regulations set by Zhu Jie for the navy, 3,500 materials, that is a giant ship with a displacement of more than 1,200 tons, it can definitely be regarded as a giant existence, I am afraid that the entire South China Sea will not be able to find a few such huge warships, as for the firepower, the various forces in the South Seas are definitely not as powerful as this flagship!
