Chu Tang: Tell Li Er at the beginning that I am a time traveler

Chapter 73
Seeing that Li Chong ran to some place and fiddled for a while, when he came back, he had a large basin of water in his hand, which was like a boat.

Li Chong put it on the ground, and first said: "You all should have seen the appearance of boiling water with a kettle?"

"I've seen it, but so what?"

Wei Zheng said.

Li Zhong: "Then have you noticed that when the water boils, the lid of the kettle will be pushed up by the heat inside, and then collide with the kettle itself, constantly making some restless sounds."

"so what?"

Wei Zhengdao.

"So, now, through this phenomenon, we can recognize a truth. The heat in the boiling kettle contains a kind of power, which is enough to lift the lid of the kettle."

"Science, first of all, is to understand the reason behind this phenomenon, find out its laws, and finally, finally apply it."

After finishing speaking, Li Chong poured water into the pipe of the puff boat and put it into the water basin. Then he used a torch to light a candle on the spoon, and then put the spoon on it. To where the heat of the puff boat is used to generate power.

The four of them watched Li Chong's actions, but they didn't know what Li Chong wanted to do.

but……

The start of the puff boat was also extremely fast. It took only a few counts, and it seemed that it had already responded. After half a minute, the boat was able to move forward freely on the water.

and……

No intention of stopping at all.

Everyone looked at this little thing curiously, even Li Lizhi was no exception, and the words innocence and curiosity were clearly written on her face.

"How can this thing... it won't stop?"

Wei Zheng felt a little surprised.

Even Changsun Wuji couldn't help but feel a little surprised, and looked at Li Er with surprised eyes.

Li Er: "Li Chong, what does this mean?"

Li Chong said: "Actually, this is the same as boiling water. I just poured water into the two pipes below the boat, but the inside cannot be completely filled with water. There will be an air bubble inside. When you heat the invisible bubble, the force generated by the bubble is the same as the force that can lift the lid of the kettle, and it can discharge the water contained in the pipe, and then push the boat forward continuously. .”

"So in theory, as long as the candles here are burning all the time, the boat will keep moving forward. Of course! This boat can only be regarded as a gadget here, but just imagine, if it can be built A similar big boat, a big boat that can carry people and goods, can move the boat forward as long as the hot water is heated on it, as long as the power is strong enough, it is not a problem even if it is sailing against the current and fighting the wind and waves, so what will happen?"

"In the past, ships often relied on what? Sails, or natural water flow, or trackers, manpower, for example, someone on the shore needed to pull the boat forward, or there was a person on the boat holding a penny .”

"But with this, in the future, you don't need to look at the weather, you don't need to look at the direction of the water flow, and you don't need to spend too much manpower. It just needs to be like boiling water. Someone remembers to add fire to the stove. "

"This is science. Take the truth hidden in this world that everyone is used to and don't take for granted, carefully understand and study it, and finally, turn it into your own use."

"As for the purpose, it is naturally to make Datang better."

"That's what the Academy of Sciences was created for."

of course!

Li Chong would never say that he just wanted to get an extra job.

To be honest, it was not his intention to promote technology to benefit the public.

Everything he does actually stems from whether it is beneficial to him to perform poorly.

Just like making a pedal reeling cart, in fact, I just want to make more clothes in Datang in the future.

In this way, he can enjoy his concubine Ji wearing more beautiful and gorgeous clothes to please his body and mind.

To be honest, he wanted to make stockings.

Women in the Tang Dynasty wore white stockings.

Just think about it...

The issue is……

This thing shouldn't be easy to handle.Moreover, his research in this area does not need to be almost, it is zero.

After hearing this, everyone looked at Li Chong fixedly.

Wei Zheng's admiration for Li Chong was even more spontaneous.

Apologetically, he said:

"I didn't expect Dean Li to think so much. Before, I, Wei Zheng, was superficial. I thought Dean Li was just a little skilled. I want to apologize here."

"Cough! It's over, it's actually all for Datang."

Li Er also had a smile on his face, and said happily: "It's all for Datang, that's a good sentence!"

Now Li Er is too picky to give rewards.

Li Chong felt sorry.

But that's right, this is the job of the Academy of Sciences. The point is, if everything is rewarded, the reward will be worthless in the future.

"So, when can you build this boat?"

Li Er asked Li Chong.

Li Chong was embarrassed for a while, and replied: "Uh... Actually, there is still a lot of gap between theory and reality. This is the difficulty of science. Sometimes, the idea is very beautiful, but the reality is very embarrassing. So when can we It’s hard to say if it was created.”

No matter what you build, it will not benefit you at all.

Let's put it off first.

However, if it can be made, it will be very good to use it to develop Jiangnan and transport the grain from Jiangnan to Chang'an.

Even if it cannot be used for navigation in the whole water section, it is not bad that it can be used for navigation on the canal.

Li Chong seemed to be able to see the iron-clad warships appearing on the canal, no, they were iron-clad grain transport ships.

Li Er didn't make things difficult for Li Chong either.

It's just that this kid has a lot of things hidden.

He said, "Besides this, do you have anything else here?"

Li Chong said: "Recently, the binoculars have been made."

Then Li Chong went to take out some binoculars that he had made.

Wei Zheng and Changsun Wuji each have one, and even Li Lizhi has one.

Li Zhong introduced: "It's just that the magnification rate is not high."

Li Lizhi stood very ladylike holding the binoculars, looking in amazement at the thing that was drawn closer to her eyes, how could this thing be so miraculous.

"What is the use of this thing?" Changsun Wuji asked.

"Use it for the soldiers at the border to detect the enemy's situation, and also use it for viewing. Look at the moon at night. But, don't hold this to the sun, otherwise, you will be blinded by the sun."

"What's the rationale behind this?"

Wei Zheng seemed to be more interested in this.

Then, while they were talking, and they were still observing with binoculars, seeing that Li Lizhi was quite close to him, Li Chong also took out a glass bead and motioned her to take it.

This bead is a high-end commodity in Datang.

Worth like gems.

Li Lizhi made a 'for me? ' expression.

Li Chong handed over again.

Then she took it.

Almost got caught.

It was she who was puzzled, why did Li Zhong give her this?Only she has it, and Father and the others also have it.But this thing looks pretty nice.
