Now Zhang You was really surprised, in his thoughts, Guo Zaoqing must have scoffed at this kind of proposal, it is impossible to think that it is feasible, now looking at his performance, it seems that he quickly recognized his words. This made him have to look at it differently, his teacher, not only has a great reputation, but also is very open-minded, it seems that in the future, there should not be the conflicts that he imagined.

He was a little relieved, a little emotional, and a little incredulous, so he asked tentatively: "Sir, do you also think that the student's idea is feasible?" ”

Guo Zaoqing said happily: "Why can't it be done? You think, Kong Ming lantern itself has weight, right? Candles also have weight, and when the heat reaches the end, they don't fly. In this case, if the lantern is made large enough and the source of fire is sufficient, it will not be able to bring people to heaven...... If you really want to make it, apply it to the military, then it will be very useful. After saying that, he slapped Zhang You on the shoulder: "You kid is really good, how did you come up with this idea?" I would have made this lantern a long time ago, but I never thought that it could take people to the sky. ”

Zhang You was a little embarrassed, his soul was standing on the shoulders of giants, and compared with Guo Zaoqing, it looked a little bad.

He smiled ashamedly and said: "Actually, the student also had a whim, I saw the tea hanging boiling water before, after the water boiled, the heat could open the lid of the pot, and the student felt curious. ”

"Tea hanger? Heat? Guo Zaoqing repeated in a low voice, thoughtful.

Zhang Jialin and Mei Niang Chunxing next to her were already dumbfounded, listening to the conversation between the two, the co-authoring is not a joke at all? How can a man fly? That's not a fairy!

The three of them refused to believe it, but when they thought that if they really made a huge Kong Ming lantern as Zhang You and Guo Zaoqing said, bringing people to the sky, that scene must be an empty alley, right?

Thinking like this, the three girls felt that their bodies were lighter, and their hearts fluttered, as if they were really flying.

Zhang You was quick for a while, and revealed the principle of the steam engine, but he didn't regret it, he was a half-witted person in this regard, and he didn't know what it was, but his teacher was talented and receptive, and he also knew a hands-on person like Xu Weiye Mengxiong, maybe he could really drum up a steam engine.

When did Watt build the steam engine with practical value?

He thought about it, it seemed to be the eighteenth century, but he couldn't remember the exact date. Now, in the 16th century, if it could be done, the first industrial revolution would have taken place in China, not in Europe.

Then when he thought of this, he was suddenly stunned for a moment, because he had suddenly found a new purpose. Before that, he just wanted to use his knowledge to make a good life for his mother. Occasionally, I have the idea of changing history, but I have never thought about it deeply. But at this moment, he suddenly figured out a truth, since he had crossed back, why did he still watch Da Ming decline step by step?

In and out of the prime minister, he really doesn't have that much ambition, but as a Chinese, it's just that he doesn't have the ability, and if he has the ability, why not contribute to the strength of the motherland?

Thinking of this, he suddenly became excited, and then quickly fell into confusion again. Some people explain that the decline is due to the complete overthrow of Zhang Juzheng's reform achievements. Some people explain that the decline and fall of civil officials are due to the fact that civil officials uphold the government and emphasize literature over military force, which reverses the end of the world. Some people also explain that the decline is really because the more than ten years of national capital struggle has exhausted the energy of the monarch and ministers. Some people even say that the fundamental reason for the decline and fall of the Ming Dynasty is the serious land annexation, the official forcing the people to rebel, and the harsh climate during the Xiaoice River period......

What is the real sticking point? What can you do if you're in the middle of it?

Improved weapons? Development of industry? Although his medical skills are good, he is not good at these. What's more, a rare genius in the world like Zhang Juzheng can only end up with hatred, and he will avoid politics in his later generations, and if he really wants to throw himself into that big whirlpool, I'm afraid he won't even be able to make a splash, right?

Zhang Youqing is arrogant, maybe there is, but that is in the field he is good at, when it comes to governing the country and leveling the world, he is absolutely self-aware, and he is not that material at all.

He couldn't help but sigh, for the first time since the crossing, he felt sorry for himself: I knew that I would cross, why didn't I learn more knowledge in the first place? It would be nice to be able to draw the structure of a steam engine. Divine doctor and divine doctor, to put it bluntly, is just Lang Zhong, who has slightly higher medical skills, and when he reaches the sky, he will be a hospital president, and he does not even have the right to participate in politics.

Thinking of medical skills, his eyes suddenly lit up: "I can't govern the country, someone will, isn't Zhang Juzheng?" He seems to have died because he had hemorrhoids and improper surgery, right? With Lao Tzu's medical skills, I dare not guarantee that I can prolong his life for three or five years, right? If you get his favor because of this, and slowly infiltrate what you know into him, the influence will be great. ”

Following this line of thought, he continued to think deeply: "Not only Zhang Juzheng, but Zhu Yijun doesn't have a headache and brain fever?" History records that he didn't have a foot disease, which troubled him for many years. There is also the queen of the main palace, who is infertile. Zhang Siwei died of a violent illness...... What about Lang Zhong? Lao Tzu can change history if he makes any move. For example, if I can make the queen give birth to a son, Zhu Yijun will **pamper** love Concubine Zheng, and he must follow the rules of the heir, right? It is impossible for the struggle between the country and the capital to arise. With this credit, Queen Wang is still grateful to Lao Tzu? Wouldn't it be logical to affect the little prince in turn? ”

The more he thought about it, the more excited he became, and his face couldn't help but bring it out, and the third girl looked at him curiously, not knowing why he was so happy, but he was embarrassed to ask. Cha Guo Zaoqing came back to his senses from his thoughts, and when he saw his situation, he thought he had figured out something, and hurriedly asked: "Zicheng, what have you thought of, why are you so happy?" Isn't that another idea? ”

"Uh, this...... The disciple suddenly thought that if Kong Ming's lantern was bigger, it might be possible to bring people to the sky. If the tea hanger is made bigger, the mouth is sealed, and only a small hole is left, the strength will definitely increase exponentially, but I don't know how big it can be? ”

"Coincidentally, I also thought of this as a teacher, but it is not easy to make such a big tea hanger, and I am afraid it is not easy to verify the extent of that power."

Zhang You nodded and thought secretly, yes, there is no welding technology now, and if you want to build a steam engine, you have to withstand the pressure, I'm afraid it will be difficult to climb to the sky.

He nodded and said: "This matter is really not easy to operate, if you really want to verify it, I am afraid that you will have to visit the capable people of iron smelting and casting, but this big Kong Ming lantern, I am afraid that the difficulty is smaller, if Mr. is willing, the student wants to give it a try with you!" ”
