Zhang Feng handed the lens to Li Shimin and smiled: "put it in your eyes and you will understand."

Li Shimin took the lens with a puzzled look on his face. He wanted to ask something, but he held back when he saw Fengzi's confident look, and put the lens on his eyes. At this moment, he felt that the people around him seemed to have grown a lot, Cheng Yaojin seemed to have two heads, and Fengzi became fat

This

What's going on?

He fiercely took off the lens and asked subconsciously, "Feng Zi, what's going on?"

Zhang Feng raised his mouth and said proudly, "this is the power of the lens. Now it's just playing a little bit. You'll know later."

Played a little?

Li Shimin was stunned.

Now you can enlarge the surrounding things. Wouldn't it be more powerful in the future?

Can you see ten miles away? Or a hundred miles away?

He is an emperor, his thinking is jumping off, and he thinks more than others.

Now it was just a model, and he thought of the possibility in the future.

Cheng Yaojin is different. He looks at the appearance of Li Shimin and Zhang Feng and yells in his heart, because there are not many things that can make your majesty so serious. Now, judging from your Majesty's appearance, it's obvious that this thing is very powerful. That bet

He didn't dare to think about it. He quickly said to Li Shimin, "show me the lens."

If it were someone else, he might have grabbed it now, but this is your majesty. Even outside the palace, he still dare not exceed the distance.

Li Shimin was pulled back to reality by Cheng Yaojin's imagination. Without saying much, he handed over the lens. Cheng Yaojin couldn't wait to take over the lens and put it on his eyes. At this point, he regretted instantly.

Because he saw that everything around him had become bigger, and even the usually small things were clear. There was no fear at all, but what was terrible was that Fengzi just said that this was only the first step. Think about it, only the first step can achieve such an effect. If all the later steps were completed, he would not have to lose.

In that case, isn't this fixed?

At the thought of this, his heart was bitter.

How can I kowtow and admit defeat because of a gambling appointment?

I really can't. let the iron bull come later. Anyway, the goods promised just now.

Thinking, he looked at Zhang Feng with a flattering tone: "Feng Zi, when can you get this thing done?"

"What's the matter?"

Zhang Feng looked at Cheng Yaojin suspiciously.

"Just ask, ask."

Cheng Yaojin smiled and tried to hide the embarrassment in his words.

Zhang Feng could see that this guy wanted to set his own words and didn't expose it, so he smiled: "this is not sure, but it should be soon?"

Cheng Yaojin smiled awkwardly, turned and ran away. At this time, he wanted to get into the mouse hole so that Fengzi couldn't find himself, so as not to mention the gambling appointment again.

"Feng Zi, show me your thing."

Li Yuan came up. He was usually bored in the deep palace. Now Fengzi has made such a novel thing. He can't bear it for a long time. It was like looking at it just now, but Erlang gave it to Cheng Yaojin, which made him unhappy. Now Cheng Yaojin has left, and he comes up.

"Here you are."

Zhang Feng handed the lens to Li Yuan and said with a smile, "just put it on your eyes."

Li Yuan smiled and took over the lens. He played with it in his hands before he was satisfied and put it in his eyes. But at this moment, he was stunned.

Because he found that he could see things clearly and clearly. What's the matter?

It turned out that his eyes are not very good at ordinary times. He looks a little vague. If he is far away, he can't see clearly at all.

Now you can see clearly with this lens? How can this keep him calm?

His face trembled a little. He took off the lens and looked at Zhang Feng excitedly: "Feng Zi, you are really so powerful. Make more for me."

Zhang Feng looked at Li Yuan with a puzzled look on his face: "Sir, what's the matter with you?"

"Oh, I can't explain clearly with you."

Li Yuan's face turned red. He didn't know how to explain to Zhang Feng. After thinking for a while, he said, "let me tell you, I used to see things a little fuzzy. If I was far away, I couldn't see clearly, but it would be better to take your lens suddenly."

presbyopia?

Zhang Feng frowned.

This was his first reaction. He couldn't see clearly from a distance. Isn't this presbyopia?

This

Datang already has presbyopia?

He looked at Li Yuan curiously: "Master Li, apart from these, do you have any other symptoms?"

Li Yuan frowned, as if thinking about what? After a while, he said: "usually there is a little acid in the eyes, swelling and pain, and sometimes inexplicable tears..."

Zhang Feng is more certain. It's fucking presbyopia. No wonder old master Li will be different from others with glasses.
