Just like I told Pei Lian, it only takes about ten days for the school palace to open. Now, the project of the school palace has been fully completed, and the exterior decoration has been completed, leaving only the center of the lake.

However, this is all slow work, and it is now mid-August, and if you wait until the center of the lake is also dug out, it will be completely delayed. Therefore, after thinking about it, Zhao Chen discussed it with Li Er and advanced the date of school.

Ten days is a short time, and for Zhao Chen, this time is too rushed, and there is a lot of work to prepare.

Because, Zhao Chen wants to make the opening ceremony a little grander and grander, and it is best to let all the Tang people remember this day.

This school palace not only poured all his efforts, but also placed all his hopes on him, because of his accidental appearance, so that such a school palace appeared in the history of China a thousand years earlier.

Therefore, it is not an exaggeration to say that it is an epoch-making product, and the emergence of the Academy Palace means that the Chinese civilization has advanced the world by hundreds of years, or simply a thousand years.

Zhao Chen didn't believe that there was an epoch-making product of the Xuegong, and those tragic things that made him regret beating his chest every time he thought of it would still appear in Chinese history.

This is the moment of the turning point of civilization, but also the moment of the adaptation of Chinese history, from this moment on, the Tang Dynasty will enter a new era.

Therefore, Zhao Chen wants to have a grand ceremony, not only to celebrate the opening ceremony, but also to celebrate the arrival of this great moment, which will be recorded in the history of human civilization.

The ceremony was celebrated at the back of the palace, behind which was a huge playground. There is plenty of space for people to attend the ceremony.

There's a lot of work to prepare. There are also many people who use it naturally, and all the gentlemen are mobilized. Not only a bunch of gentlemen, but even the people from the new military camp were all brought over.

He San brought his group of people, all of whom came, and under the command of Gong Doudou, they were building a color platform, which was two meters high, occupying almost one-tenth of the playground.

The role of the color platform is not only to speak. Moreover, there will be a unique performance, so there are some things that need to be designed and completed.

The gentlemen were not idle, at this time, they were following Zhao Chen to experiment with the problem of water pressure, and they were all shining just because. Zhao Chen told them that at that time, through their hands, a rainbow would be created. All of them are going crazy.

The preparatory work is carried out in an orderly manner, and the people of the entire school palace. are not idle, Pei Lian, Li Gang, Wang Xiaotong and others. It has also come in advance.

However, these few people. After completing the big-character task delivered by Zhao Chen, he sat on a few chairs leisurely, discussing Confucianism with the bookworms in the hidden door, and watching Zhao Chen and others who were busy.

Probably in the entire school palace, among the busy people at this time, there are only a few of them, and they are the most leisurely!

Artificially made rainbows, which in the Tang Dynasty, will be considered crazy, because the ignorance of nature has led to the special worship of the 'gods', believing that these are all masterpieces of God.

Therefore, the artificial creation of rainbows, for them, is naturally a fool's dream, just look at the gentlemen, when they first heard about it, that kind of skeptical look, you know.

In fact, the artificial creation of rainbows could not be simpler for future generations, as long as the process is understood, even children can make it.

Find a basin of water, put a mirror in it, and then align it with the sun, reflect the sunlight on a wall, and a colorful rainbow projection is complete.

However, the rainbow that Zhao Chen needs is naturally more than just a rainbow projection, what he needs is that in the sky above the color platform, a rainbow bridge is assumed, and the effect is definitely very eye-catching.

Assuming that a rainbow bridge is placed in the future generations, there is naturally no problem, or, as long as Zhao Chen's supermarket is upgraded again, there will probably be no problem.

But now, it's a bit of trouble!

The formation of the rainbow bridge requires two pipes, the front end of the pipe is equipped with a sprinkler, and then, the two pipes, corresponding to the direction of the sun's direct rays, spray out a misty water mist, and the rainbow will naturally appear.

The matter of pipes can be solved in the supermarket, the yellow pipe can be solved, and the sprinkler can also be solved, and the only problem now is the problem of water pressure.

If there is not enough water pressure, it will not be possible to achieve the effect of high-speed jetting, and the rainbow created will not be effective. At this time, if there was a water pump, it would be solved, but unfortunately, the supermarket had not yet appeared, and Zhao Chen rummaged for a long time, but only found some sprayers with very little pressure.

I deliberately took it out and experimented with it, and as a result, the effect was greatly discounted, and it could not reach the power of the jet rainbow bridge at all.

In desperation, Zhao Chen had to use the most primitive and stupid method to use the power of air to make a booster by himself.

The materials are all ready-made, the original sprayer, all removed, and then, re-increase the pressure pipe, fortunately, he needs not much water to spray the rainbow, only more than 20 kilograms of water is enough.

The key point of the booster lies in the sealing of the air, just the problem of sealing, which made Zhao Chen spend most of the day, repeatedly, but always failed at the last moment, unable to achieve the role of full sealing.

Later, there was really no trick, so I had to shrink the pressure pipe a little bit, the distance of the spray, and at the same time, the spray distance of three meters, the pressure pipe finally withstood the water pressure.

"Try it!" After shortening the water pipe again, Zhao Chen held one end of the water pipe, looked at Li Jingheng next to the booster and said.

"Okay!" Li Jingheng has always been out of character, and most of the day's experiments have long made Changsun Chong and others lose their patience, but Li Jingheng still maintains a high level of interest.

At this time, hearing Zhao Chen's words, he excitedly agreed, and immediately tightened the pressure lever and pressed it down.

With Li Jingheng's movements, the water in a wooden bucket next to him was constantly sucked into the pressure pipe, and a moment later, under the stares of the surrounding gentlemen, Zhao Chen opened the valve on the water pipe.

The moment the valve was opened, the sound of air discharge was heard in the water pipe, and then, a water mist sprayed out violently from the nozzle at the front of the water pipe.

“… It's done! Seeing a mist suddenly erupted, the gentlemen who were originally sitting on the ground suddenly came to their senses, and their mouths squeaked excitedly, and they rushed towards Li Jingheng and Zhao Chen.

"Get out of here!" Li Jingheng accompanied Zhao Chen for most of the day, and had already regarded the booster as his personal belongings, and when he saw the gentlemen pounce, he immediately blackened his face and yelled. The expression is hideous, and if you don't agree with a word, you will fight with others.

Seeing this, the eldest grandson smiled 'hehe', sat down on a booster next to him with a hippie smile, and announced loudly: "This belongs to a certain family!" ”

The booster has been successfully developed, although the shape is a little ugly, and the spray distance is relatively close, but it will be no problem to create a rainbow bridge at that time.

Subsequently, after the second booster was also manufactured, Zhao Chen adjusted the direction on the spot under the eyes of a group of gentlemen and experimented on the playground.

At this time, it was noon, and the sun was hanging high in the sky, and the sun was blazing.

When a mist of water sprayed out of the two water pipes at the same time, under the surprised eyes of everyone, a colorful rainbow bridge suddenly appeared in the sky above the playground.

“… Color... Rainbow! "The Rainbow Bridge hangs high in the sky, and you can see it clearly from a long distance.

At this moment, the whole playground, the busy people, all stopped, looking at the rainbow hanging high in the sky, looking dumbfounded.

The rainbow has always been considered by them to be a masterpiece of God, however, this moment was created by Zhao Chen.

Looking at this spectacular scene on the playground at this time, several old gentlemen who were originally talking and laughing suddenly stopped talking, trembling their fingers, pointing to the rainbow bridge hanging in the sky, and their hearts were shocked for a while.

However, just when everyone was attracted to the rainbow, the originally colorful rainbow suddenly faded in the air like a flash in the pan.

"Hey!" As soon as Zhao Chen saw the rainbow disappear, he couldn't help but roll his eyes, turned around angrily, looked at Li Jingheng and Changsun Chong, who were in a state of obsession with others at the same time, and cried out depressedly.

These two or two goods, just competing to be strong, want to manipulate the booster, as a result, after the rainbow bridge appeared, they were obsessed for a while, forgot their own work, and amazed with others.

"How can this be true, it is simply unreasonable!" Li Gang, who was originally disappointed when the rainbow disappeared, suddenly became angry, and when he realized that the culprit of the rainbow's disappearance was the eldest grandson Chong and Li Jingheng, he suddenly scolded angrily.

The person next to him who was watching in amazement heard Li Gang's scolding, and for a while he also scolded with righteous indignation, so frightened that he quickly lowered his head and tightened the pressure rod.

The rainbow appeared again, and everyone looked at the rainbow obsessively, and their mouths kept 'tsk' and smack.

Seeing such a scene and imagining the sensation caused at the ceremony, the corners of Zhao Chen's mouth couldn't help but rise slightly, revealing a smug smile.

"The old man has lived in vain in this life!" The rainbow lasted for a while, and finally because the water had been sprayed, under the regretful gaze of everyone, it disappeared gloomily, Li Gang looked at the disappearing rainbow stupidly, couldn't help but sigh, and sighed.

Hearing Li Gang's exclamation, several people next to him nodded with deep feelings, and echoed together: "That's it, it's not in vain!" ”

It's just that these words fell on Zhao Chen's ears, but he couldn't help but smile, the rainbow was just his first show.

At that time, there will be more shocking things, I don't know if these old gentlemen, after seeing it, will they sigh that this life has been overturned. (To be continued.) )

PS: Sure enough, I had a cold, and I was uncomfortable for a day!
