Great Tang’s Unparalleled National Teacher

As I was thinking about it, Li Shimin's voice rang: "Feng'zi, since you know the problem with Daoist School's father's eyes, then you can help."

In fact, he knows all of Li Yuan's problems, but the imperial doctor in the palace is not effective. I don’t know how many times it has no effect. And now Feng'zi's lenses actually have an effect, it must be done by the other party. Help.

Zhang Feng can understand what Li Shimin father and son said, and he is naturally willing to help. After all, this resin is not worth money, but the experiment has not been completely successful yet, so he said: "Old Li, Old Li My grandfather, there is nothing wrong with what you said, just a presbyopia, but the lens has not yet been fully tested successfully. After the experiment is successful, I will give a pair of glasses to Mrs Old Li and it will be completely resolved."

"Presbyopia? Glasses?

Li Yuan and Li Shimin looked at each other, a little confused, and asked, "What are these things?" "

Zhang Feng forgot a question. These words are too forward, and these guys don’t understand, so they just explain it casually, and the two of them are just at this moment.

Alkinnon came back with a brush.

Zhang Feng didn’t say much to everyone. After all, it’s important to be a Telescope, so he just sat on a stool and started polishing.

Cheng Yaojin was boring, so he didn't want to cheekily go to see, so he asked Cheng Chumo to inquire. At first Cheng Chumo refused, but when he saw Feng'zi, the stuff was quite novel, and he already got together before he waited for the violent beating of the old man. In the past.

Li Shimin and Li Yuan are two father and son, not to mention, they are in the deep palace all the year round. Now they see such a powerful thing, they naturally don’t want to let it go. Moreover, this thing is still similar to Li Yuan’s eyes are related, so the two leaned together in front of Zhang Feng, like a rare treasure.

About the time it takes to burn one stick of incense, Zhang Feng stopped. Action, stretched: "Finally finished. "

Cheng Chumo couldn't wait to ask: "Feng'zi, how's it going?" "

He can say that he is looking forward to the result now, because he already knows that Old Ghost is going to use himself to fulfill the bet. If Feng'zi really succeeds, then he will give Feng'zi. Knocking his head, this is the last thing he wants to see, so he least wants Feng'zi manufacture to succeed now.

Zhang Feng doesn’t know this, he just thinks this guy is curious, so he said ill-humoredly : "What is the urgency? I haven't watched it yet? "

Speaking, he picked up the lens and put it in front of his eyes, and a smile was unconsciously raised at the corner of his mouth. Obviously, the effect this time has surpassed just now. Not only things can be seen clearly, but also those in the distance Things can also be Amplification.

Zhang Feng’s smile quickly attracted Li Shimin’s attention. He curiously asked: "Feng'zi, how about this time?" "

"Come on, you try. "

Zhang Feng smiled and handed the lens to Li Shimin.

Li Shimin couldn’t wait to take it, and when he saw it in front of his eyes, he instantly felt that the whole person was not good. The poor effect just now is not a little bit, it's like a sky and an underground. Now not only can you see clearly, but also things in the distance can be amplified.

He put down his lenses and looked at Zhang Feng with surprise. : "Feng'zi, how did you do this? "

Zhang Feng raised his head and said proudly: "these all are trails, the lens has not been completely finished yet, and it needs to be polished again. When the two lenses are put together, you will know the effect. . "

Looking at what Feng'zi said about the mystery, Cheng Chumo couldn't help but curiosity in his heart, and quickly said, "Can you show it to me?" "

Li Shimin hearing this handed the lens to Cheng Chumo, Cheng Chumo took it, put it on his eyes, and shouted inwardly, because he saw a very clear scene, then this is not Prove that his head is going to be knocked down?

Thinking of this, he has a bitter look on his face, and he can't help but complain that the father cheated his son, and is angry that Feng'zi has made this magical thing, but he has no choice but to do it. Give the lens to Zhang Feng again, and smile again and again.

Zhang Feng seems to have seen Cheng Chumo's abnormality, but he will not pity this guy. Who makes Old Chen want to bet? Now It’s too late to know that it’s wrong.

He handed the lenses to Alkinnon, with a serious face: "Continue to polish according to the method I just did, and then make five identical ones, and finish the delivery. give me. "

Alkinnon is nodded, took the lens and left. He just saw the dean’s manufacturing process, and he probably wrote it down. There is no problem with manufacturing.

Zhang Feng naturally believes in Alkinnon. After explaining everything, he sits back on the stool as if everything has nothing to do with him.

But everyone’s curiosity has been completely aroused, how could it be possible? Dismissed by these two sentences?

Li Shimin approached Zhang Feng and said with a smile: "Feng'zi, how far can you see if you succeed in doing this thing?" "

He has seen it just now, and the small things around five meters can be seen clearly. If you can see farther, maybe it can be used in industry or military. This is for Great Tang. , Are all beneficial.

Zhang Feng seems to see Li Shimin's thoughts, said with a smile: "Old Li, do you have any thoughts? "
