The Blue Cat is not a human, so Huang Chao would not give birth to the sigh of "Is this still a human?" It is obvious that the super-powerful Blue Cat's refinement starts from every bit in daily life. The so-called "key-breaking game" of Aunt Chicken gave Huang Chao an intuitive understanding of the combat power of this world.

He was covered in fire, and the blue cat ran away from the city gate yelled and said: "I'm burning to death!" His movements were still lively. At this time, he saw Huang Chao and Feifei watching on the side, and said happily: "Brother Huang Dog, Feifei, come and help!"

Feifei saw his embarrassed look and shrugged: "I really can't do anything to you." As Feifei said that, she bent forward, her orange tail spinning at high speed, like a propeller of a helicopter, and he actually lifted himself off the ground and flew under the city wall at a low altitude.

Huang Chao had already seen that although the blue cat Feifei was very scammed on the surface, their essence was superheroes. So Huang Chao also let himself go, shook his head and pointed ears, and suddenly jumped three feet high: "Brother Blue Cat, I'll help you!"

Huang Chao's punch was so heavy that he punched the city wall with the momentum. The city wall hit by his fist bulged up at that time, and a wave spread from Huang Chao's fist to all directions. It was his effect similar to earthquake waves...

"My hands hurt a little." Huang Chao thought awkwardly.

The naughty, curry and fat guy above were swept by the ripples, and the three mice were tilted around, and finally, circles of dizzy birds appeared on their heads, unable to support them and fell to the ground.

The blue cat laughed with his hips underneath: "Hahaha, brothers of yellow dogs, you're doing a pretty job!"

Huang Chao pulled up the blue cat with one hand, as if he was pulling up a strand of leeks from the vegetable field: "Brother Blue Cats, come on!"

Amid the terrified screams of blue cat, he was thrown by Huang Chao from under the city wall and rushed directly to the three mice that could not be avoided. When the blue cat saw that he actually grabbed the enemy, he immediately forgot that Huang Chao threw him directly without saying hello, and laughed and said, "You mice are surrendering. With me and the Yellow Dog brothers, you can't win."

Huang Chao rushed to the city wall, stomped his feet on the ground, and pulled the onion onions on the dry land and flew up two feet high. Then he broke a few times in the air. Not only did he not land, but he became higher and higher, falling to the wall. The reason why it was so fancy was to conform to the mainstream of this world.

Naughty whispered: "Isn't this a dog meddling with rats?" What he said makes sense, Huang Chao and Blue Cat couldn't refute it.

Feifei finally dug through the city wall, and then found that the two elder brothers in his group had already stood on the top of the city and controlled the three people in the mouse group. He could only take out a gun from behind, aim it at the three mice, and play his role: "Take the answer quickly."

That’s right, they played for so long, and they all completed all the way to heaven and earth. In fact, this is a fun teaching game. They successfully developed the problem and obtained the answer to “How the earth was formed”.

Faced with Feifei's threat, the three naughty people showed disdainful expressions of death. Blue Cat had already responded to this. He grabbed the fat man and carried him outside the city wall with the two straps of his overalls in his scream: "If you don't tell me, I will throw you down." With Blue Cat's big strip, you can definitely do it.

Fatty immediately admitted his defeat: "Okay, okay, the answer is for you. You three robbers."

He walked towards a fortress on the city wall, knocked on the brick wall, and moved the bricks outside away, revealing the computer display inside, which immediately showed the teaching screen:

“How did the earth form?”

"The Earth was born with the birth of the solar system: At the beginning of the solar system, it existed in the form of a huge and constantly rotating cloud cluster composed of dust and gas. It is composed of hydrogen and helium generated by the Big Bang, and it also has other elements synthesized by the inside of the planet a long time ago. Because the cloud cluster rotates, gravity and inertia press the cloud into a disc, which is perpendicular to its rotation axis. Most of the mass is concentrated in the center and the earth begins to heat. At the same time, because gravity causes matter to shrink around the dust particles, the remaining part of the disc begins to decompose into rings. Fine debris collide with each other and form larger fragments."

"The earth's matter is composed of many parts gathered in a zone about 150 million kilometers from the center. When the sun contracts and is heated, the nuclear fusion begins, and the solar wind formed thus clears the matter that does not shrink and forms larger individuals in the disc, leaving only a small amount of elements. After that, the heavier elements gather near the sun to form small and high-density star bodies (earth-like planets); the lighter elements gather farther from the sun to form large and low-density star bodies (earth-like planets), and the earth is the third closest to the sun."

"In the early Ancient Times, the Earth had no oceans and there was no oxygen in the atmosphere. The remaining matter after the formation of the asteroid and the solar system continued to collide. These impacts combined with the heat generated by radioactive disintegration, residual heat and heat generated by the contraction pressure, making the Earth completely melted at this stage. Heavier elements sink to the center, while lighter elements rise to the surface, thus creating different levels of the Earth. Scientists believe that the inside of the Earth can be roughly divided into three concentric circles with different compositions of matter and properties. The outermost layer is called the crust, the most central part is called the core, and the middle layer is called the mantle. If the internal structure of the Earth is used as an image metaphor, it is like an egg, the core is equivalent to the egg yolk, the mantle is equivalent to the protein, and the crust is equivalent to the eggshell."

After hearing the explanation, the blue cat asked: "So why is the only earth in the solar system where is life?"

There is still the next level, and the three naughty people went to guard the next level dejectedly, but found that they could not beat Blue Cat and the other three. Speaking of which, the three mice were naughty and had combat power, while Huang Chao and the others had excellent combat power. Blue Cat was known as "super power" and was not just talking about playing.

When he arrived at the next level, Feifei was stimulated by his cat and dog brothers, and no longer hid himself. He took out a single cannon barrel from behind, aimed at it with his naked eyes and fired directly. His inclination was so perfect that the shells fell into the most appropriate position, blowing the castle into ruins. Looking at his masterpiece, Feifei smiled with satisfaction.

"Go and get the answer." Huang Chao said. He and Blue Cat quickly found a golden treasure chest, and after opening it, it was the computer that played the teaching video.

"The Earth is ranked third among the nine planets in the solar system. It is 150 million kilometers away from the sun. This distance allows the Earth to obtain enough energy, especially the suitable temperature to maintain life. Compared with other planets, the Earth has the appropriate mass and volume, attracting the atmosphere that supports life. During the formation of the Earth, its internal spheres continue to move, causing crust movements such as volcanic earthquakes..."

"The Earth's magnetic field also resists solar wind and cosmic rays that can kill organisms. The Earth's formation time is just right. After its surface cools, the active activity of the earth's core prompts a large amount of carbon dioxide and water vapor to be discharged into the atmosphere, which is crucial for the surface insulation and the formation of water. Volcanic activities also emit a large amount of methane, which is the basis of early biological formation. Early lower organisms rely on the substances emitted by geological activities to create oxygen that can be used for later biological survival. Finally, after billions of years of transformation, they formed our home today."
