Li Yan was very curious and couldn't help but ask Zhang You: "What are telescopes and microscopes?" With them you can subdue someone with eyes above the top? ”

Zhang You smiled and said nothing, but Qian Wugua was interested, and said with a smile: "Big brother, look at your face, the new one, right?" You still don't know how powerful our Lord Zhang is, that's why turning your hands into clouds, turning your hands into rain, turning decay into magic, and turning ...... In a word, he is a genius among geniuses, and there is nothing he can't ......"

"Stop, stop," Listening to Qian Wugua touting himself so hard, Rao is Zhang You is thick-skinned enough, and he couldn't listen to it anymore, "Old Qian, didn't you use to be a pirate before, if you didn't know, I thought you raised cattle, and if you blow it again, the cowhide can make you blow up!" ”

Li Yan sneered, very charming, but Lao Qian didn't pay attention, and muttered in a low voice: "Who bragged?" Originally, hot air balloons, telescopes, microscopes, parachutes, that ordinary people can make it? His face was full of unwillingness, as if all his achievements were made by him.

Xu Guangqi is the same age as Zhang You, and he was also born in the 21st year of Jiajing.

To tell the truth, he is not particularly handsome, his eyebrows are very thick, a little garlic nose, the wings of his nose are slightly larger than normal, his lips are very thin, and he looks a little mean, but his eyes are very bright, black and white, and he is very energetic.

He was wearing a gray-white cloth robe, very cleanly washed, and a pair of black cloth shoes under his feet, trimmed with white steps, and the top was spotless, not at all like he had just traveled a long distance.

This is a very self-disciplined person, Lao Qian judges well, and is a bit clean.

After looking at Xu Guangqi, Zhang You secretly commented.

Zhang You is looking at Xu Guangqi, Xu Guangqi is also looking at Zhang You, to be honest, he actually doesn't feel how powerful Zhang You is, most of the reason why he went to Beijing is because of the hot air balloon that can bring people to the sky.

Very handsome, the moon-white brocade robe is very in line with Zhang You's temperament, if you don't consider his somewhat inconvenient right foot, as long as the eyes are not blind, you have to praise him for being a dragon and phoenix.

It's a pity......

What a cripple, huh?

Xu Guangqi was a little disappointed, and clasped his fists and saluted Zhang You: "No, Xu Guangqi, I've seen Master Zhang, you can call me Zixian." ”

His attitude was very polite, but his tone showed a faint detachment, according to reason, Zhang You's official residence was seventh, he was just a small talent, and it was actually legitimate to call himself a "student".

Qian Wugua snorted coldly, very dissatisfied with Xu Guangqi's attitude.

Zhang You didn't seem to be aware of it, and said very enthusiastically: "It's really good that Zixian can come to help me, these two know each other, right?" He pointed to Guo Zaoqing and Zhao Shizhen next to him: "This is my mentor, Mr. Guo Zaoqing, Mr. Guo, this is Zhao Shizhen, who is very interested in firearms......

"I've already met, it's just very strange, I think I'm unknown, and I'm far away from Beijing, how can an adult not enter Beijing from thousands of miles away?"

It is said that it is very unreasonable for him to interrupt Zhang You, but this is actually a question that Guo Zaoqing and Zhao Shizhen have always been very curious about, and when they heard this, they couldn't help but focus on Zhang You, Guo Zaoqing smiled and said: "Yes, Zicheng, about this issue, you kid has been secretive, and now that the main master is here, you can't hang our appetite anymore, right?" ”

Zhang You had been prepared for this question, so he was not flustered, smiled slightly, and said: "Actually, I didn't mean to hang everyone's appetite, but this reason is a bit far-fetched, I'm afraid that you won't believe it......"

"You didn't even say how do you know if we're going to believe it?" Zhao Shizhen interrupted Zhang You with a smile.

"Actually, I've heard others mention Zixian's name, saying that he has some insights into firearms research...... I once had dinner in a restaurant, and I happened to hear the person at the next table talk about it, and I didn't pay attention to it at the time, but then Gewu Institute was founded and needed talents, so I remembered Zixian and checked, there is really such a person, and he has just won the show......"

How does this sound like a blind fabrication, but Zhang You has already been vaccinated, and everyone has nothing to say, which can be regarded as a success of being prevaricated by him.

"It turns out that Brother Zi also has research on firearms, that's a coincidence, we can be more close to each other in ......the future" Zhao Shizhen smiled and was close to Xu Guangqi, but Xu Guangqi didn't seem to appreciate it very much, and said reservedly: "My lord is serious, isn't it just that I occasionally make some remarks about firearms, and I can't talk about the word research." ”

The second half of Zhao Shizhen's words were directly blocked by Xu Guangqi, and he couldn't help but glance at Zhang You with some embarrassment, and said in his heart that this person is really uninteresting enough, and adults are ridiculous enough, but it is hearsay, so he invited him from afar, and he may not have real talent to learn.

"Sir, Changji, if you have something to do, go ahead and get busy, and I'll accompany my son to go around first." Zhang You said roundly, suddenly remembered something as he spoke, and looked back at Qian Wugua: "By the way, old Qian, don't pestle here, go get me some quicklime, I'll be of great use." ”

Everyone dispersed, only Zhang You, Xu Guangqi and Li Yan were left in the house, Zhang You stretched out his hand and said to Xu Guangqi: "Gewu Institute was founded, the conditions are still a little simple, I will accompany you to take a look around, I think I can show my strengths, just stay, if you can't, I also said clearly, I will send you back with a gift." ”

Xu Guangqi glanced at Zhang You in some surprise, nodded, and did not speak.

"This is a glider, people grab the handle here, jump down from a high place, and glide by the resistance of the air......" In the finished product exhibition hall, Zhang You first explained to Xu Guangqi the big kite-like glider, and was interrupted by Xu Guangqi before he finished speaking: "Air? It's a word invented by adults themselves, right? Isn't it the void between heaven and earth? ”

Zhang You smiled and nodded: "You also said that it is the breath of nothingness, you can't see it or touch it, isn't it empty?" That's why I'll call it air. ”

Xu Guangqi nodded, slightly disapproving: "The principle of this glider should be similar to that of a kite, however, the wind direction is uncertain, according to adults, if people operate on it, the risk is still not small, and the actual use does not seem to be too great." ”

"That's right, so, this is also the reason why it has not been officially included in the training subjects of the Heavenly Battalion, and only a small number of people who are particularly brave take the initiative to carry out experimental training, which is still in the stage of exploration."

"What about hot air balloons? Isn't there a finished product in Gewu? Xu Guangqi asked.

Zhang You said: "The hot air balloon is now supervised by the Inner Government Military Bureau, and there is no finished product on the side of the Gewu Institute...... Speaking of this, he saw Xu Guangqi obviously showing a disappointed expression, and couldn't help but smile secretly, and continued: "However, there are two things that will definitely open your eyes and subvert your previous cognition......"

"Oh?" Xu Guangqi interrupted Zhang You again, his expression obviously a little disapproving.
