Europe has just ended its dark age in the Middle Ages. Even if it is ahead of China in technology, it has not formed a crushing force for the generations. This war seems to be at a disadvantage in the Ming Dynasty, but it has not yet reached the point of surrendering!

Zhu Cixuan pushed open the meal and said, "When Kui Xin, the two gentlemen Tan Shi finished their meal, please invite them in."

"Your Highness, are you uncomfortable? Or are the food not up to your taste?" Lu Suyao whispered.

Zhu Cilang just shook his head. He had decided to fight this war for future scientific world talkers, and naturally entered a state of war.

If the Ming Dynasty loses, it will only completely give up its position as the world hegemon and become a regional power. However, if the Ming Dynasty wins, the whole world will have to accept the Ming Dynasty's science and cultural system in the future. Moreover, this advantage will grow stronger and stronger with the development of the times. Just like the United States in later generations, the intellectual elites of the world will tilt towards them and flow in.

After Wang Zheng and Xiong Mingyu were summoned, Zhu Cilang took them to the ear room. The three of them sat down and discussed in depth the topic of "Wentong". For the old scholars and officials who were extremely sensitive to Wentong, the two did not think that the crown prince was making a big deal, but just praised the crown prince's foresight and high-level perspective.

"The gap between my Ming Dynasty and Taixi is only lies in the use of scientific methods, and there is no cross-generational barrier. If a generational difference is formed in technology, once Taixi blocks my Ming Dynasty and does not let the technology flow out, China will likely suffer its humiliation." Zhu Cixuan paused and said, "So I isolated Johnson Chan in the technology of casting iron mold cannons."

Wang Zheng looked cold and said, "Your Highness's concern may have happened."

"What do you mean?" Zhu Ciyang was quite surprised. Did the West realize the blockade of the East so early?

Wang Zheng shook his head slightly and said, "The old minister remembered that when Xu Shanghai wrote that when he was translated by the beginning of the translation of the "Taixi Water Method", Xiong Sanba repeatedly shirked his responsibility and refused to help. In this letter, Xu Gong even used the stern words "It can be seen how this man is" to deny his character. However, afterwards, he looked at his preface and said that it was a turnaround. The old minister thought that if Xiong had not deliberately kept his private affairs, it must have been Long Huamin who issued a secret order to him."

Zhu Cixuan said, "I am not surprised by this. Westerners were not as selfless as they said. Moreover, those who deal with our country now are missionaries, and they are the best academics in Taixi. The nobles, warriors, and merchants are all barbaric and vulgar, and profit-oriented. If they form suppression in the future, I am afraid that our country will be to Taixi, just like North Korea will be to Ming Dynasty."

This analogy was not too heavy to Zhu Cilang's opinion, and even had the suspicion of beautifying Taixi. Because the Ming Dynasty had never colonized and plundered its vassal states... but it sounded too terrible to the literati and officials of the Ming Dynasty.

"It seems that there is something that may not be convenient for Mr. Tang to know about it." Wang Zheng said seriously.

"What is it?" Zhu Cixuan's heart moved.

"Your Highness, please move." Wang Zheng said: "This is discovered by the minister and Professor Song from the ancient book of Taixi translated by Professor Fang. Logically, Mr. Tang knew it, but for some reason, he did not seem to be valued in Taixi."

Zhu Cilang became even more curious about this. If it was an ancient book of Taisie, it should be a book from ancient Rome and even ancient Greece before the Renaissance. Fang Yizhi's recent research direction is really a bit biased, but it does conform to his character of pursuing the roots.

Xiong Mingyu wanted to avoid it, but was kept by Wang Zheng.

Even though Wang Zheng believed in Catholicism, he still had the awareness of defending against China and the barbarians. History proved that when Catholic doctrine conflicted with the idea of ​​loyalty to the emperor, Wang Zheng would definitely choose the latter. He could torture himself for life by taking a concubine. Because this violated the only doctrine of mutual loyalty between Catholic couples. When the Ming Dynasty was destroyed, even if Catholics committed suicide strictly, Wang Zheng still went on a hunger strike and died.

...

Zhu Cilang changed into casual clothes and followed Wang Zheng all the way to his own laboratory.

The windows of the laboratory have been replaced with large pieces of flat glass, and the room has excellent lighting. Judging from the experimental tools for furnishings, Wang Zheng's main research field is still focused on mechanical manufacturing.

Wang Zheng's stepson Wang Yongshun was already waiting in the laboratory. He saluted the three of them, and immediately took out a wooden box that was one foot square under Wang Zheng's instructions.

Wang Zheng took out the key from his bag, opened the wooden box, and said, "The power of this thing is probably beyond everyone's imagination..." As he said that, he took out a strange model made of brass and iron from the box.

"Turn the ball?" Zhu Cixuan said in dismay.

"Your Highness knows this thing?" Wang Zheng was quite surprised and accepted this fact naturally in an instant.

The crown prince was originally a knowledgeable and knowledgeable person, and there were many of the Far West magic weapons presented by Matteo Ricci back then. If he had seen them, it would be no surprise.

The rotary ball is the work of the ancient Greek mathematician, inventor and philosopher Hero. It was born in the first century AD.

Hero connected a hollow metal ball and a closed pot with water together with two hollow tubes, and then heated it at the bottom of the pot to make the water inside boil. The water vapor enters the metal ball from the hollow tube, and finally the water vapor will be sprayed out from the nozzles on both sides, causing the sphere to rotate.

Compared with the steam organ, vending machine, syringe invented by Hiro... the steam rotary ball is just a pure ornamental toy and has no practicality.

However, this thing was the ancestor of steam engines in later generations, and it was also the key cross-age project that Zhu Cilang had discovered after he thought hard, and after preparing for peace in the country, he made great efforts to tackle key issues.

Wang Zheng repeated this experiment and successfully turned the steam ball, saying to Zhu Cixuan: "Your Highness, this is the power of steam."

Zhu Cilang nodded.

"However, the real power contained in it is..." Wang Zheng moved away the small stove below, and after the water vapor gradually weakened, he stuffed two plugs into the nozzle of the steam rotary ball.

Soon, I heard the closed iron pan below making a "bang" sound, concave inward. The two plugs on the nozzle were also obviously sucked in.

"A vacuum is formed after the water vapor cools down." Zhu Cixuan said casually.

"That's right," Wang Zheng said, "the suction force generated in this way is very huge." He put on leather gloves and tried to pull out the pull-out plug, saying, "If it is enlarged, it may not be matched by the power of a hundred people."

——This is indeed the principle of a condensing steam engine, but it is also like a mutated Maddleborg hemisphere experiment.

Zhu Cixuan touched his chin and said, "Actually, this is a problem of air pressure. The air pressure in the sphere is lower than the outside atmospheric pressure, so it seems to be sucked in, but it is actually pressed in."

The atmospheric pressure experiment is the classic wooden barrel destruction experiment, which Zhu Cilang also talked about in "Physics".

"Why did you think of making this?" Zhu Cixuan asked.

Wang Zheng did not get confused about the words, because he always habitually forgot Zhu Cilang's level of knowledge when studying things. He replied: "This is what Professor Song thought of when verifying the nature of qi. If qi is indeed a thing and has the effect of thermal expansion and contraction, it will inevitably produce force. Making this bulb is just to verify it, but by chance, it is possible to create a new machine based on this object."

"But the difficulty lies in how to make it repeat itself and continue to grow." Zhu Cixuan said.

Wang Zheng's beard trembled slightly, and he spit out two words that made Zhu Cilang dizzy:

“Not difficult.”

Wang Zheng asked Zhu Cixuan to come to his workbench and took out a circle of rice paper. After unfolding it, it turned out to be a three-dimensional perspective view, and even light and shadow rendering. You can tell at a glance that he learned the skills of Thai oil painting.

"This was written by my nephew Yongshun." Wang Zheng explained, pointing to the mechanical diagram: "Since I know the principle and have made a model, all I have left is to change the shape and calculate the force arm to make it lasting and powerful."

Zhu Cilan's eyes followed Wang Zheng's fingers on each of the decomposed maps, and completely entered a calm working state. This was the first time he saw the decomposed map of the steam engine in his past and present life.

As a liberal arts student, and never thought that he would be reborn in the Ming Dynasty after his death, Zhu Cilang certainly could not prepare various industrial knowledge like a prophet. With his common knowledge of science and engineering, he could still see the complexity of Wang Zheng's steam engine at a glance. However, under Wang Zheng's introduction, each component is key and has been so concise that it cannot be simplified.
