Zhang You was stunned for a moment, then he remembered that he was talking to Ye Xianggao and them, and he actually forgot about Shen Yongmao, and couldn't help touching his nose: "Brother Jing said that I laughed, I'm afraid that you won't appreciate the light, if you want to come, who dares to stop you?" ”

said with a smile, and said: "By the way, you have always been very busy, why do you have time to come to the cold house?" ”

"I'm going to the Three Treasures Hall for nothing, no, my father heard that you have returned to Beijing, and specially asked me to give you an invitation, it was originally scheduled for tonight, but didn't you say that you were going to feast these young handsome people tonight, just change it to tomorrow night! It just so happened that I had been curious about Mr. Jin Yong for a long time, and my sister was strict-mouthed, and she never told me Mr. Jin Yong's true identity, just to see the true face of Lushan. ”

The second assistant personally sent his eldest son to invite not to mention, but he actually took care of his emotions and temporarily changed the time, this guy is really more popular than people.

The three young postgraduates were dumbfounded and secretly envious, but they didn't know that if they continued to develop according to the original historical trajectory, their future scenery would be better than today's Zhang You. (Zhang Fuzhi, the fourteenth year of Wanli, the successive military science and the department of the department to the matter, Taichang Siqing, one of the nine Qing, although not as high as the above Congzhe and Ye Xianggao, but also a high-ranking official.) ）

"This ...... Say it earlier, I'll say it sooner...... That's right, it's not too late to change the time, Jinqing, you heard it, we can't let the second assistant wait, let's change the banquet to tomorrow. ”

"Don't don't, I can't wait to see Mr. Jin Yong, my father has nothing important to do with you, I'm in charge, you go to my house tomorrow night, don't wait tonight."

Shen Yongmao hurriedly said, now Zhang You had nothing to say, so he had to agree with a wry smile, thinking hard in his heart, although he and Shen Shixing "released their previous suspicions" and had a good relationship, it was the first time that they were invited to dinner, and they didn't know what medicine the old man sold in his gourd.

In fact, it doesn't matter if the three of Ye Xianggao come to the house, but they just come here to deepen their impression and pave the way for future development. According to the reason, foreign officials rarely have a tacit relationship with Jinyiwei, but Zhang You is different from the previous commanders of Jinyiwei.

Needless to say, the trust of the emperor and the strength of the backers behind him are also unprecedented, and even the second assistants of the current dynasty are willing to make friends, not to mention these young people who have not yet stepped into the official career.

In fact, both sides are well aware of these situations, but no one is willing to take the initiative to break them.

They stammered with Zhang You, why didn't Zhang You want to have a good relationship with them?

Tiannan Haibei casually gossiped, but fortunately, although Zhang You is not as good as those who read, other knowledge is very profound, every strange remark, always has sufficient arguments, and is amazing, and these people are stunned and dumbfounded.

As he spoke, the topic somehow came to Jiangnan, Guo Zaoqing asked, "I heard that you convinced Wang Shizhen with a question?" That's a master in the literary world, a grandmaster-level figure, hurry up and talk about it, as a teacher, I only know the rough, and I have long been itching. ”

Later, this matter spread widely, there are any versions, but the specific content is unknown, and several other people have also heard about it, and when they heard Guo Zaoqing ask this, they were immediately amused and curious.

Zhang Jialin couldn't help but interject: "Yes, Xianggong, just listening to the rumors outside, the concubine is also very curious." ”

The feeling of watching everyone is still quite enjoyable, Zhang You smiled and said: "Actually, it's nothing, I almost forgot about it, it seems to be some common sense problems, such as how wide the ground is and how high the sky is, etc., mainly because the foreign situation has moved Mr. Wang, don't look at his age, and he has suffered setbacks, but his heart is still hot, I hope our Ming will become stronger and stronger......"

"How wide is the earth, and how high is the sky? Mr. Zhang, this kind of problem ...... Do you know the answer? Among the students, Fang Congzhe was the youngest and the most lively, and he couldn't help but interrupt Zhang You's words in a daze, his expression was very exaggerated-the sky is round and the place has been known since ancient times, and no one has calculated the specific value, can this also be calculated?

The expressions of the rest of the people were also quite exaggerated, it was true that everyone had never been exposed to these things, but Guo Zaoqing, because he had been in contact with Zhang You for too long, and he was not surprised to hear him say something occasionally.

"How wide is the earth? The earth is actually round, and Westerners call it 'Earth', and I translate it as the earth, which is about 80,000 miles in diameter, and there is no doubt about that, because there have been people in Europe who have traveled around the world. As for the question of how high the sky is, it is easy to explain, the maximum altitude at which the Tenbei flies in a hot air balloon is about 10,000 meters, and at that altitude, the air becomes very thin, and I speculate that if you keep going up, it may become a vacuum without air...... I coined the word myself, for example, the air we breathe is colorless and transparent, but you can't say it doesn't exist......"

Speaking of this, Zhang You stopped when he saw that they were ignorant, looked around, saw the teacup on the coffee table, and suddenly his eyes lit up, and he took out a silver ticket from his arms, then took the teapot, poured water on his teacup, covered the silver ticket on it, covered it with his hand, and then turned the teacup over, and asked: "Guess what if I take the hand below?" ”

"The water is heavy, and it will naturally flow down!" Fang Congzhe said first, with a look of disdain on his face.

Shen Yongmao and Ye Xianggao didn't speak, their expressions were a little puzzled, and Zhang Fuzhi said with some hesitation: "The tea should be dried up in an instant, adults don't think that the silver ticket can block them, right?" ”

"Jialin, what do you think?"

Zhang Jialin shook her head, her big eyes were shining, she felt that the tea should not flow down, she knew too much about the magic of her father-in-law, but she felt that this matter was too unreasonable, and she couldn't believe it.

After the suspenseful sound effect of ......five cents was automatically played, Zhang You said, "Now, it is the time to witness the miracle", and the hand holding the silver ticket was taken away instantly, but he saw that the silver ticket was holding the tea in the cup steadily, and not a drop was spilled.

"Why?" Several people asked in unison.

Zhang You shook his hand under the silver ticket: "Because there is air, the air is colorless and tasteless, and it is difficult to see, but it is real, it is they who hold the tea in the cup...... There is not a trace of space between the tea and the silver ticket, and there is no room for air, if the tea is not satisfied, it will be the same again......" said and held the silver ticket to flip the teacup, uncover the silver ticket, pour out a part of the tea, cover the silver ticket, and reverse it again: "Look, that's it!" With the departure of his hand, the tea instantly rushed away the silver ticket and fell to the ground.

"Don't look at me like that, it's not a trick, anyone can do it." Zhang You paused, looked at Guo Zaoqing, and said with a smile: "Seeing magic in the ordinary, this is the charm of Gewu." If it weren't for the grid, how could you have thought that the ordinary sulfur, saltpeter, charcoal, and after grinding, could be combined in a certain proportion to become a powerful gunpowder? If you are interested in these things, when you have nothing to do, you should go to the Gewu Institute, and although the words of the sages are important, the invention of Gewu is actually indispensable for the strength of the country at certain times. ”
