After that, Wu Zheng went to see the third type of steam engine, which had begun to assemble a simple crankwheel to change the direction of force transmission according to Wu Zheng's design, which made the machine evolve from a simple up and down motion to a cyclic motion.

So, Wu Zheng took out the drawings that had been prepared long ago, and introduced to the two of them the principle that the cylinder gas pushes the piston, and the piston makes the wheels move forward by driving the crankshaft.

Wu Zheng's next stop is Wusong Port.

Shen Tingyang, the left attendant of the household department, has not moved in this position since he was placed by Wu Zheng from Shaoxing Mansion to Wusong Port four years ago and served as the city's shipping secretary.

Shen Tingyang is undoubtedly a doer, otherwise, with his identity as the right attendant of the Sanpin Military Department and the left squire of the Household Department when he was in Lu Jianguo, he would not have deigned to come to the City Bo Division to do a five-grade promotion.

But then again, under Lu Jianguo, he served as the right attendant of the military department and the left attendant of the household department, and Shen Tingyang had more than a dozen people under him, and he thought that there were less than 100 people under Zhang Guowei, the secretary of the military department, who could command at that time, so he said that Shen Tingyang, the servant.

But now, although Shen Tingyang is only a five-grade promotion, he has 1,200 craftsmen and tens of thousands of employees, which is by no means the same as in the past.

Of course, it also depends on Shen Tingyang's character, he likes to do things and doesn't like to be an official.

In the past four years, the Wusong Port Shipyard has built 39 large and small ships, and the largest sea ship is 1,200 stones, but it is still not enough for the warships that Wu Zheng needs, especially the gunboats.

Indeed, the shipbuilding industry of the Ming Dynasty lagged behind Western Europe too much in just one jia.

Shen Tingyang did his best to build the largest gunboat, which was only eight heavy guns and twelve rapid-fire guns, and could not make any progress. It should be noted that this number is not the number of guns on the single side, but on the port side.

Compared with the more than 100 guns of the British Sea King, the gap is not ordinarily large.

The recoil of heavy artillery bombardment, especially when firing a salvo, was enough to cause the hull to fall apart, which was not something that could be solved by the craftsmanship mastered by the craftsmen at this time.

Therefore, the purpose of Wu Zheng's trip was not to put pressure on Shen Tingyang, but to appease Shen Tingyang.

Because of Shen Tingyang's plea, he has already been on the third time, and he really can't build a sharper battleship.

Accompanied by Shen Tingyang, Wu Zheng inspected the entire port and shipyard.

But he stopped in front of a courtyard less than two miles in length.

The black tile and gray wall is ordinary, but the sound of Langlang reading inside makes Wu Zheng stop.

Shen Tingyang was a little nervous, he explained: "The number of craftsmen and employees gathered in the port has reached more than 10,000 people, wives and children, and then they are young and old. ”

Wu Zhengdao: "How many children? ”

"More than 1,500 people in total."

"Where did the gentleman come from? What to learn? ”

"In addition to recognizing some words, it is to learn shipbuilding and ship repair. There is no gentleman, just the craftsmen and hired workers in the port, who take turns teaching the children. ”

"Where does the money come from?"

"This ...... This....... Shen Tingyang plucked up the courage and said, "I have the courage to embezzle 5,600 taels from the shipbuilding funds...... Guilty of lowly duty. ”

Wu Zheng slowly turned around, "You are indeed guilty!" It is not a small sin to divert the king's shipbuilding funds for other purposes! ”

Shen Tingyang hurriedly argued: "The prince can rest assured, the humble position is only misappropriation, and he will never dare to cut corners and use shoddy goods when building ships." ”

Wu Zheng didn't speak, Gu himself walked inside, and followed closely behind, leaving only Shen Tingyang there in a daze.

After a while, Shen Tingyang stomped his feet slightly and chased after him.

These courtyards, in the shape of a "U", are covered three times in front and back, inside and outside, and the facilities are simple but complete.

Looking in from the window, the children's clothes were neat, Wu Zheng was still satisfied, the General's Mansion had made a minimum limit on the minimum monthly salary for the employees and people under his rule, and the monthly salary of a strong laborer should not be less than one or two.

According to the price of rice in Hangzhou, he can feed his family without starving to death, which is the limit of what Wu Zheng can do.

Because only he knows in his heart that the money he lacks is gone.

If it weren't for some windfall, the General's Mansion would have gone bankrupt this year.

But the appearance is bright, not glamorous, all over the world, overseas businessmen will not come, businessmen, this thing, has always been the icing on the cake, will never send charcoal in the snow.

Pushing open the closed door of a classroom, Wu Zheng didn't realize whether he was affecting the child's class.

Wu Zheng glanced at a more restrained boy.

"Xiao Langqi, can you tell me your name?"

The kid glanced at Wu Zheng with some horror, and then looked at his husband.

The obviously unmeritorious "Mr. Ye" was also a little stunned, but when he saw Shen Tingyang, who came later, waved his hand and signaled, he stopped talking to stop Wu Zheng.

Seeing that Mr. did not stop him, the child replied softly: "My big name is Sun Yi, and my little name is Goudan...... The daimyo was changed when he was studying. ”

Wu Zheng laughed and said, "Yo, Sun Yi, this name is good, who changed it for you?" ”

"My mother!"

"In this way, your mother should be a person who has read books."

"Nope. My mother is illiterate...... But now I can teach my mother to read, and I know a lot of words. ”

Obviously, this child's "introverted" is pretended, no, just ask a few words, and it will all come out, Wu Zheng feels a little funny.

So he continued to tease him: "It's not right, your mother doesn't know how to read, how can I name you?" ”

The child was anxious and defended: "It's the name my mother gave me, oh - that's my brother, his name is Sun Zhen." My mother said that my father died in Yizhen, so my younger brother and I are called Sun Yi and Sun Zhen. ”

Wu Zheng's smile froze, and he looked back at Shen Tingyang.

Shen Tingyang hurriedly stepped forward and explained: "This is the family of the Yizhen fallen soldiers who came by the prince before. ”

Wu Zheng nodded slowly, turned around, and asked the child, "Studying here, what about your mother?" ”

"My mother washes clothes for people, and she can earn a penny by washing five pieces."

Wu Zheng nodded and said with a smile: "Then what are you doing here to study and eat?" ”

Shen Tingyang squeezed up and said, "Lord Wang......."

Wu Zheng turned his head, frowned, and scolded softly: "Shut up, go aside." ”

Then he changed to a smile and said to the child: "Tell the uncle, okay?" ”

The child replied, "Just eat here, the school will give us food and don't charge any money." ”

Wu Zheng's smile was even stronger, "What does the academy give you to eat?" Isn't it delicious? ”

The child suddenly took out half a sweet potato from your cloth pocket and showed it to Wu Zheng.

Wu Zheng's smile was a little stiff, and he forced a smile and asked, "Is there anything else?" ”
