Chapter 309 The Wonderful Academy

After all the calculations, he forgot that Li Yuan's ancestor was a barbarian.Li Yuan's dragon claws didn't hit Yunhao's head, it was the result of years of improvement in moral cultivation.

From ancient times to the present, the influence of Confucianism is powerful.Yun Hao is not stupid enough to fight against Confucianism, but who said that it is impossible for a big tree to have vines on its body?Let you flourish and go straight to the sky, but I am just a vine climbing up your body.From time to time, I have to draw some nutrients from you.

The result of crawling is that the vine is as tall as the tree.Even the vines may be a little taller than the big trees!

The more Li Yuan visited Yunhao's teaching building, the more surprised he felt.Which one of those strange glass vessels is not worth a thousand gold.Yun Hao dismissed the experimental equipment with a single sentence. Could it be said that this kid is already rich as a country?This has to be asked, although I still feel at ease with Yunhao in my heart.But the royal family wants to control everything in this country, as long as things beyond the royal family's control are of a different kind and need to be monitored, serious ones will disappear from the world.

I saw Yun Hao use a mirror to set a piece of paper on fire.Li Yuan felt more and more miraculous. He pulled Yun Hao away and played with the magnifying glass.

"Your Majesty! This experiment proves that the propagation path of light is straight. A convex lens can focus light, and a concave lens can diverge light. The academy is looking for a suitable crystal, using this principle, to polish it into a lens. As long as the roundness of the polishing is suitable , you won’t be so strenuous to read the memorial. I say that stuff tastes like glasses!” Looking at Li Yuan who was enjoying himself, Yun Hao bowed and said.

"You have filial piety...what? Can I see things clearly?" Li Yuan's presbyopia has become more and more serious in recent years, and now it is extremely difficult to read the memorial.Hearing that Yunhao had something that he could see clearly, he immediately threw away the convex lens and approached Yunhao, staring at him and asking.

"Yes, that thing can be placed on your ears. It allows you to see things clearly. It's just that the glass made by the academy is not pure enough. The best way is to use crystals, but you can't find a suitable pure crystal for a while. .”

"Tomorrow...no, now you send someone to pick in the inner mansion, and you can take as long as the inner mansion has it. Take it as soon as possible!" Li Yuan, who was troubled by presbyopia, couldn't bear it anymore.Now that I heard that there is a way, I immediately ordered Su Jin to send someone to take the craftsmen to the inner mansion.It's just a pure crystal, if you need a pure diamond, there is no problem.

Let Yu Lao's big apprentice go to the palace, anyway pick the good ones to take.There are many treasures in the palace, so one or two less is not a big problem.

There are three mirrors at the entrance of the laboratory, and Li Yuan in the sunken mirror has a round watermelon head.The one next to him is just the opposite, with his head diverging like a sachima.Li Yuan looked at it for a while, feeling a little dizzy.It's better to use a normal mirror, the mirror shows every detail.Eyebrows and beards are clearly photographed, there is such a side in the Taiji Palace, Li Yuan has to be photographed once a day to straighten his clothes.Although, Su Jin corrected his clothes eight times a day.

There are concubines with face in the harem, but it depends on the degree of favor.Mirrors range from full-length mirrors to small mirrors.Yun Hao had seen some fingernail-sized ones before, but he didn't know who to use them for.

Li Yuan also saw a huge glass fiber reinforced plastic, and Yun Hao just injected water and air into an iron tube.It can control this thing to float on the water surface, suspend, and sink to the bottom.

Kongming lanterns are not new. It is said that they existed during the Three Kingdoms period.When he was in Jinyang, Li Yuan himself let it go.But Yunhao described on a piece of paper that as long as the Kongming Lantern is big enough, it can take people to the sky.Fly!This is the dream of many generations, can this kid achieve it?

But Kongming lanterns have been cast by themselves, so a small one can take away three taels of lamp oil.If it is old enough, what this kid said is very likely to be true.

Magnets are not uncommon, just magnets.Yunhao said that the handle of the spoon made of magnet must face the north.Li Yuan turned around a few times curiously, and sure enough, he faced the north each time.

"With this thing on the battlefield, the soldiers will no longer have to worry about getting lost." Yun Hao was about to explain the principle of geomagnetism to Li Yuan, when he heard a "呵" laugh beside him!

Looking back, his face sank immediately, and it was not someone else who laughed at him.It was Changsun Xiaozheng's father, Changsun Shunde.

"Does Xue Guogong have any advice?" Seeing the members of the eldest grandson's family, Yun Hao felt uncomfortable.Over the past two years, the elder Sun's family has often tripped up the Yun family both openly and secretly.The two families did not fight once or twice in private. Of course, the Yun family, which owns the vast sea, still had the upper hand.

Li Yuan usually turns a blind eye to the disputes between the nobles.As long as the innocent are not hurt, no one will pay attention even if they die.The Li family has Hu people's blood, and disputes between nobles on the grassland are usually resolved in this way.

"This thing may work on land, but what needs guidance most is on the water. If the old man is on the water, you can still use this thing if the water is bumpy? Even on land, how do you let the soldiers carry such a heavy thing? .There can’t be a dedicated person in the army to carry things.” After Changsun Shunde finished speaking, Yunhao rolled his eyes.

Today, I came with Li Yuan just to give Yunhao eye drops.I didn't expect to see a lot of novel things along the way, let alone pick faults.I can't even understand it!If you pick the wrong one, you will be laughed at by this kid.Changsun Shunde looked at the thing in front of him for a long time, and finally made up his mind after thinking about it for a long time, so he jumped out to embarrass Yun Hao.

"Huh!" Yun Hao snorted, and took out a needle-shaped magnet.I took another stick with a small hole in the middle!

"Xue Guogong, you can take care of it." Yun Hao threw the small wooden block with magnet needles into the water basin and spun it a few times.The magnet needle actually pointed north again.

"On the sea, this water basin will be made of closed glass. No matter how rough the waves are, it will not affect its use."

"Hahaha! As for the land, could it be possible that you let the soldiers carry pots on their backs wherever they go...!" Zhang Shun and Sun De spoke halfway, but couldn't continue.Because Yun Hao held a palm-sized glass ball in his hand.Inside is a magnet needle, no matter how Yun Hao rolls over.The magnet needle always points north.

The eldest Sun Shunde's face suddenly turned into a liver color, and he really couldn't beat the fox and made a fuss.Yunhao's sharp teeth are well-known in Chang'an, so there must be harsh words coming out from below.Changsun Shunde was even ready to be sprayed into a sieve!

"Your Majesty! I have a message!" Yun Hao was about to speak when Wen Daya suddenly jumped out.
