Since he pulled the "back" who was going to die together, and there was also a "imperial grandson" in it, Wei Renshi said that he would do it, left the matter of the drill to Li Liang, and went to Weinan early the next morning.

When I arrived at Zhuangzi, I went to the glass kiln and told the old kiln head and the blowing man the size and shape of the convex lens I needed.

It happened that there was molten glass waiting to be blown on the glass kiln, and the blowing person performed a blowing technique in front of Wei Renshi, and Wei Renshi was shocked.

It only took three or four blows, and the convex lens that Wei Renshi wanted was blown out for him.

Wei Renshi waited for the annealing of the convex lens to be timeless, and went to the blacksmith raised by Zhuangzi and asked him to make a metal cylinder to charge the eye tube and fix the prisms of the convex lens.

Then he stayed in Weinan and waited.

also took the opportunity to be lazy and break away from the barracks to rest and rest.

After staying in Weinan for two days, the blacksmith of the blacksmith shop came over with his things.

In the end, Wei Renshi invited Weinan to raise in Zhuangzi is a blacksmith in the blacksmith shop, his craftsmanship is really good, the metal cylinder produced is not different from what Wei Renshi requires, and there are even carved veins on it for decoration, which looks very tall.

The convex lens on the glass kiln was also annealed, and the old kiln head also sent it, and happened to bump into the blacksmith, so they came together.

Wei Renshi took the convex lens and drew strokes on the metal cylinder pen, which is basically very suitable, and it can be installed with a little grinding.

Suddenly, Wei Renshi was stunned, and said in his heart that the convex lens and the metal cylinder were there, but how to glue the convex lens into it? It's not enough to just get stuck there, but there's no glass glue at this time!

Thinking of this, Wei Renshi turned around and asked the old kiln head: "Old kiln head, do you say there is anything more sticky than paste, and the sticky thing can be very strong?" ”

"What does Xiaolang want to dip into?" The old kiln head scratched his head: "The old man knows that rice soup and paste, and the sticky things on our kiln are all made up by clay." ”

Well, Wei Renshi has a black line on his face, the rice grains in the rice soup are not sticky at all, and the paste and paper are fine, but it is a little difficult to stick the glass to the metal cylinder.

"Xiao Lang wants to stick to the objects in his hands?" The blacksmith looked at what Wei Renshi was holding and asked.

"Exactly, I don't know if Master Tan has a way?" Wei Renshi's eyes lit up, and he hurriedly asked.

The blacksmith smiled and replied, "The texture of the glass is hard, but ordinary paste can't stick to it, Xiaolang can try fish maw glue." ”

"Fish maw glue?" Wei Renshi was stunned, what is it?

The old kiln patted his forehead and said, "That's right! The old man didn't use this thing often, and he didn't think about it for a while. Xiao Lang, this fish maw glue is made by taking the swim bladder in the belly of the yellow croaker and drying it, so that the water is boiled, and then hit it with iron, that is, it becomes gelatinous, and it will become very sticky. ”

The blacksmith nodded, and added, "Carpenters make wood, and sometimes they use it to stick hardwood. ”

"That's great!" Wei Ren was overjoyed: "Where can I get this glue?" ”

"There must be quite a few carpenters." The blacksmith said, "The little one is going to find it for Xiaolang!" ”

Wei Renshi nodded, there is a carpenter's workshop on Zhuangzi, there must be one there.

After a short time, the blacksmith came back with the fish maw glue, Wei Renshi assembled the convex lens, the metal tube and the prism together, tried to expand and contract a few times, the telescopic of the metal tube Zheng was very free, not too tight and not too loose, and then got up and walked quickly to the outside of the study, and looked at the branches in the distance.

Well? The effect is surprisingly good!

Wei Renshi was suddenly very happy in his heart, and hurriedly ran out of the courtyard, asked people to carry a ladder, climbed up to the roof along the ladder, and looked farther away with the monocular in his hand.

As the other eye narrowed, the eye facing the telescope gradually became clear.

Wei Renshi looked at it for a long time, estimated it, and could see the human form clearly from 800 steps away, and saw his every move clearly, but he couldn't see his face clearly.

However, it should be seen to see the drills of the soldiers in the Shence Army.

After lunch that day, Wei Renshi left Weinan with a telescope and went straight to Chang'an City.

When I arrived in Chang'an City, I rested for the night, and the next morning, I immediately went to the army with a telescope.

When they arrived at the barracks, the soldiers had already begun to practice.

Wei Renshi kept holding on until the end of the training before calling Li Chun and the others into the military tent.

"A few days ago, I said that I wanted to make an object that people could see far away, and after all kinds of experiments, I finally made it." As he spoke, Wei Renshi took out the binoculars in his arms and handed them to Li Chun.

"This ......," Li Chun took the telescope and looked left and right in his hand.

Everyone gathered around and looked curiously, Wei Renshi understood that Li Chun would not use it, so he explained: "Prince Chun went to the door, put the thin end in front of his eyes, closed the other eye, and then looked into the distance. ”

When Li Chun heard this, he put the telescope in front of him as Wei Renshi said, then closed his other eye, walked to the door of the tent and looked up into the distance.

I saw that he suddenly took a few steps back, and quickly put down the things in his hand and looked forward, revealing a surprised look.

Li Chun looked at the soldiers who came from afar, put the binoculars in front of him again, and was suddenly startled, put down the binoculars, and looked at the group of soldiers again, but found that they were not close.

"Can this object bring people closer to a distance?" Li Chun looked at the telescope in his hand in surprise: "I used this object to look at it, and I saw that they were already in front of me, but when I put it down and looked, it was still so far away." ”

Wei Renshi was very satisfied with Li Chun's surprised appearance, so he explained with a smile: "This thing can help people see the scenery far away, even if it is far away, it is as if it is in front of you. Prince Chun will look at the place next to him? ”

Li Chun did so, took the binoculars and turned his body to look into the distance.

"This ...... This thing ......" Li Chun gasped while looking around: "Immortal magic weapon!" Absolute immortal artifact...... This...... I'm afraid I'm a few hundred steps away! Belch! ”

When everyone heard this, they all hurriedly gathered around and were eager to try, Li Chun handed them the binoculars, and after they saw them one by one, they all gasped and were shocked.

"This, this is really clairvoyance!" Li Liang's frightened mouth couldn't close, and he kept shouting.

"Carving insect little tricks, if you are interested, I can teach you the principle." Wei Renshi smiled very sneeringly.

How, are you curious about how this is done?

Hahahaha, it would be nice if it could arouse Li Chun's interest, arouse Li Chun's curiosity, and fool Li Chun to learn more about scientific knowledge and truth.

He is the emperor of the future, and if he is interested in these things, then these things can be valued and developed!
