"Holy." Cheng Chubi looked disdainful and said, "If it is a god, your brother-in-law and I are gods." ”

"But this elephant can spew rainbows." Li Zhi said.

"You can spew a rainbow, you can take a sip of water and spew it out at the sun, you can spew a rainbow." Cheng Chubi said.

"Really?" Li Zhi was still a little unconvinced.

"Is it true that practice produces the truth, and you will know if you try it?" Cheng Chubi rolled his eyes, none of these bear children were worried.

Li Zhi ran to the side, then scooped up a scoop of well water and sprayed it into the sky.

After a few seconds, Li Zhi's face showed a look of great joy, and said: "Really, really, I spewed out a rainbow, I spewed a rainbow, I am also a god, I am also a god." ”

Everyone looked at Li Zhi with idiot eyes, and many people secretly wondered in their hearts, these two fools are right? Whose fool is this?

"Brother-in-law, brother-in-law, it's really amazing, it's amazing, it's ...... What the hell is going on? Li Zhi asked excitedly.

The current Li Zhi is not a black-bellied little emperor, he is still very curious about things, and I don't know if he still has the plot of loving his mother.

Now Wu Meiniang is already Li Shimin's justifiable concubine, and it is said that she will be listed as one of the four concubines in a few days, and I don't know if she will come to hook up with Li Zhi.

"What kind of artifact is this? It's called science. Cheng Chubi glanced at this guy and said: "This is the refraction effect of light, the sunlight hits the air and is close to the spherical small water droplets, causing dispersion and reflection. When sunlight hits a water droplet, it is incident at different angles at the same time, and it is reflected at different angles within the water droplet. The reflection of 40 to 42 degrees is the most intense, causing the rainbow we see ......"

Li Zhi looked at Cheng Chubi, and the expression on his face became even more adoring.

I don't understand it, but it's very profound.

"Let's go, I'll make it more fun for you later." Cheng Chubi said, and led the three of them to the workshop, and at this time, he had already ordered someone to bring some saltpeter back.

In all pharmacies, there is saltpeter.

In this day and age, saltpeter is a medicine.

Ordered someone to bring a plate of water, and then Cheng Chubi put the saltpeter into the water. After a few seconds, the water began to freeze inside.

In less than a few minutes, a plate of water turned into a plate of ice.

"This ...... This...... Could this be the legendary Xuanming Divine Palm? Li Zhi was speechless in shock.

"That's right, it's the Xuanming Divine Palm." Cheng Chubi laughed and said, "You can also call it an exothermic phenomenon." Saltpeter is added to the water, exothermic and frozen, it's that simple. ”

Then, he put a handful of saltpeter into Li Zhi's hand, and said, "You can also try it yourself." ”

"Really?"

"Am I still lying to you?" Cheng Chubi rolled his eyes and said.

Li Zhi carefully put the saltpeter into another plate of water, and then watched the water turn into ice, and the whole person was as if he had been struck by lightning.

Shocked, really shocked.

It's incredible that there is such a thing in this world.

It's incredible!

"See? That's the power of science. Cheng Chubi looked proud.

"Science, is the power of science really so powerful?" Li Zhi asked.

"The power of science, heaven and earth, is omnipotent."

"This ...... Isn't this a god? ”

In the eyes of everyone, this heaven and earth are immortals, people in this era would not have thought that there would be airplanes and submarines in the future, in their opinion, heaven and earth, they are immortals.

"Actually, it's not a fairy." Cheng Chubi smiled, then looked at everyone and said, "Let's take the simplest heaven." As long as you make a large Kong Ming lantern, you will naturally be able to send people to heaven. ”

"This ...... It's just incredible! Li Zhi couldn't help but sigh.

His teachers hadn't taught him that before.

"Isn't it unbelievable, you just make one?" Cheng Chubi laughed and said, "If you can really make it, maybe you will be famous in history in the future." ”

Isn't it? The guy who made the hot air balloon is famous in history.

Looking at Li Zhi's expectant look, Cheng Chubi was happy and said, "However, if you want to make a big Kong Ming lantern, you have to learn physics and chemistry first." ”

"What is physics? What is chemistry? Li Zhi asked.

"Physics is the principle of all things, as the so-called changes are inseparable from it, as long as you master physics, you will master all things. As for chemistry, it is the science of the change of all things, such as the matter of water turning into ice, which is a combination of chemistry and physics. Cheng Chubi said.

Although it is said that Confucianism has risen in the Tang Dynasty, physical chemistry is not what a certain era in later generations said. There are many, many cattle in this era.

"Where can I learn that?" Li Zhi seemed interested, which was much more fun than the one who was in the sky.

"Here I am." Cheng Chubi looked like a matter of course.

"Students meet teachers." Li Zhi actually bowed to Cheng Chubi, which made Cheng Chubi take a big jump.

Hurriedly said: "King Jin, don't be like this, if your father knows about it, and you don't peel my skin, you can still call me brother-in-law, as for other things, I will hand it over to you after a while." ”

At this time, Cheng Chubi didn't dare to accept students, especially if this student was still Li Zhi.

Not to mention Li Shimin, if this matter is known, it is estimated that those imperial envoys and officials will be able to spray Cheng Chubi to death.

"Okay, now that so much ice has been made, let's give it to the animals." Cheng Chubi said, and hurriedly hugged a plate of ice cubes and walked outside.

Everyone followed, quickly went to the panda park, came to the panda park, and directly put the ice cubes into the park, and those pandas came happily to Cheng Chubi one by one, holding the ice cubes busy.

There are so many animals in the zoo, why is there only a panda hugging an ice cube?

In fact, there is no way, who made the panda a national treasure?

In the entire Tang Dynasty, and even in the future, the number of pandas has not been more, this is a rarity, a rarity among rarities.

Then there were bears and tigers, and then other animals.

It took a long time to put the ice cubes in the place where the animals were.

However, there was not much saltpeter left at this time.

Cheng Chubi hurriedly ordered someone to spread the news and buy a large amount of saltpeter.

The merchants of the Tang Dynasty had the most sensitive noses, and hurriedly ordered people to transport saltpeter into Chang'an City.
