After Li Chenghua finished speaking, he simply bent down and picked up a brick!

Then, as soon as he tried, the brick was broken!

“…”

Seeing the hard bricks, they were actually made into half like tofu in Li Chenghua's hands?

The students of the Imperial College were all stunned!

Needless to say, these weak students?

Li Chenghua's previous move was enough to shock even among the generals!

Li Chenghua ignored the shock of everyone at the scene at this moment.

He knocked two bricks and said, "See? Will these two bricks collide and cause vibration?

Well, that's actually the principle of earthquakes!”

"Ah, it turns out that this earth movement is so simple? Chenghua, your explanation is really easy to understand!"

At this moment, Tang Bohu bowed to Li Chenghua with conscience.

The thin talented man opened his mouth for a while, but said unconvincedly: "You said there are no immortals in the sky? Then, two years ago, why did there be two days in the sky? Could it be that this was not done by the immortals?"

Lee Seung-hua smiled and said, "There was a fantasy sun that appeared a few years ago?

Well, of course this is not done by a god!

Why are there multiple suns in the sky? That is actually [Phantom Sun]!

Do you know that there is a layer of clouds and mist in the sky very high above the ground.

This layer of clouds is composed of ice crystals. Ice can reflect light like a mirror! In some special circumstances, it will create a [Phantom Sun] phenomenon.”

"This... I don't understand!"

All the talents were confused.

Lee Seung-hua scratched his head and said angrily: "Is this difficult to understand?

Look at this pool, the sun shines on the pool, is it a bright reflection?

Well, if you throw this pool into the sky and turn it into a reflective mirror, it is possible to produce a second sun! You guys understand?"

"Oh, I seem to understand..."

Although everyone is not confused, they still understand something.

Li Chenghua sighed: "Therefore, the legendary Houyi shooting the sun is just a myth!

【Fantasy Sun】It will be destroyed when it reaches a certain time! There is no need to shoot with a bow and arrow!"

"Ah, [Fantasy Sun]? Is Houyi's shooting of the sun fake? It's like this? Then, why does the sun and the moon lose money?"

Lee Seung-hua said: "What you are talking about is solar eclipse and lunar eclipse?"

Let me put it this way—now, the light can shine directly on you. If I stand in front of you, I will block the sunshine/

The sunshine cannot shine on you!

This is the reason for solar eclipses and lunar eclipses - there is a planet in the sky that blocks the sun or the moon, so everyone can't see the sun and the moon... Do you understand?"

"This...is that simple?"

Everyone was stunned.

Tang Bohu said: "Chenghua, I think what you said is so good!"

At this moment, a butterfly flew on the flower in front of it.

Tang Bohu said stunnedly: "Chenghua, why can't we hear the sound of butterflies flying? We can all hear the sound of mosquitoes and flies!"

Li Chenghua patted Tang Bohu and said, "You, you have such a great observation ability! Why can't you hear the sound of butterflies flying? Because the butterflies' wings flap less than 20 times in one second!

But our ears can only hear more than 20 vibrations per second. This is related to frequency, so there is no need for you to understand."

"So that's it! By the way, Chenghua, I have a brother who everyone says that we speak in a consistent voice! But I always feel that my voice sounds better than my brother! Why is this?"

Li Chenghua was surprised and said, "Wow, can you even think of this? Well, this phenomenon is the [skull effect].

How to say it? When you listen to your brother's voice, it is your ears that receive your brother's voice. This is a single channel.

However, there are two channels for the sound of your speaking! One is the sound of your ears hearing your own speaking!

One is that your throat vibrates when you speak, and this vibrates to your brain and forms another sound.

Adding up these two channels, you will feel that your voice is fuller, more magnetic, more pleasant and better than your brother's voice!”

“Ah? This…

‘Bone Effect’? It’s amazing!”

Li Chenghua smiled and said, "It's not 'bone', it's 'skull', it's the bones of the head.

Well, how to prove the skull effect? ​​You can block your ears with your fingers and then listen to them - do you feel a vibrating sound on your head? Well, this is the skull effect."

"That..."

Next, a group of students surrounded Li Chenghua and kept asking questions! Li Chenghua also answered one by one.

There are some people who cannot answer, so Li Chenghua temporarily recorded it and planned to check it with his mobile phone before talking about it.

Li Chenghua kept saying something that refreshed the students of the Imperial College, and made the talents on the scene gradually convinced!

Tang Bohu said excitedly: "Brother Li, you are so amazing! It is so honor for me to meet you!"

Li Chenghua smiled and said, "Brother Tang is polite. I just talk to each other! We will communicate later when we have time. We have something important to do, so let's say goodbye first."

Next, Li Chenghua and others continued to visit the Imperial College, and then Li Chenghua felt confident.

Li Chenghua talked to Li Yingge, Fang Yiai, and Ma Zhou said: "Hey, the reason why the Tang Dynasty flourished is because it focuses on education.

Next, Ma Zhou said with a little confusion: "Chenghua, it rained that day, really there was no Dragon King?"

Li Chenghua nodded and said, "Of course! Will I still lie to you in this regard?"

Ma Zhou nodded a little confused and then said, "How to solve the drought?"

Li Chenghua shrugged and said, "How to solve the drought? To put it bluntly, there is only one way, that is, to build water conservancy!"

Ma Zhou smiled bitterly and said, "Yes, Yun Xian's father just wanted to build water conservancy and didn't want to ask the Dragon King for rain?

That's why I lost my official position!”

Li Chenghua nodded and said, "I know this, and I have also investigated his affairs.

Some of the reservoirs built by Wang Yunxian's father are good! The water storage capacity is very good.

However, the canal is a big problem - there is no way to transport the water in the reservoir to arid areas!"

Ma Zhou's eyes lit up and said, "Yes, that's it!

Now all the main canals in various places are filled with soil!

When encountering drought, even if some water is transferred to the drought land, the water will be absorbed by these soil ditches.

Everyone knows this, but they can't find a solution!"

Li Chenghua nodded and said, "Yes, we currently have some rivers that can be transferred to water, but these water is like blood. Before we can reach the arid areas that need life-saving, we are sucked dry by those soil trunks.

Those soil trunks can be called "vampires"!

To solve this 'vampire'?

There is still a way! That is to lay all these main canals with stones!"
Chapter completed!
