In less than an hour, the earthy yellow dust suspended in the sky was completely swept away by Wu Jiaoyang's control of the world embryo, and even the harmful substances suspended in the air in the past, Wu Jiaoyang did not let go of the all-earth air.

Absorbing all the dust suspended in the earth's atmosphere, a thin layer of earth has appeared in the embryo of the world, but there is still a big gap before it is truly formed.

"As the mass of the Earth increases, so does gravity." Wu Jiaoyang's mind was thinking rapidly, "Gravity will affect the body structure of living beings, under gravity in the past, humans who could grow up to two meters tall can now only grow to about one meter nine at most." ”

The size of the living being's body is directly related to the energy that can be stored in the body, and Wu Jiaoyang does not want it, because of the influence of gravity change, the body of the living creature will become smaller, which will affect the energy stored in the body of the living being.

The stored energy is related to the spiritual power, mental power, and even soul energy that a living creature produces every day, if the body of a creature becomes smaller, it will directly affect Wu Jiaoyang's income, and thus affect the development speed of the entire earth.

"In ancient times, the oxygen content on the earth far exceeded that of today, and even more than doubled the current level, and the creatures at that time were huge in size and powerful." Wu Jiaoyang searched for the memories inherited from the core of the previous earth, and one by one the huge creatures like mountains, just walking, it was like an earthquake, flicking their tails, and the mountains were directly overturned and collapsed by the terrifying physical force.

"I can gradually make the system of living beings on the earth huge by adjusting the overall oxygen content of the earth, and at worst it can offset the small problem of body size caused by the change in gravity." Regulating the content of oxygen has a lot to do with the plants on the earth, involving the law of wood and the law of creation, and now although Wu Jiaoyang can use these two powers, the energy required is extremely huge.

But Wu Jiaoyang was not discouraged in the slightest, the change of gravity is not instantaneous, but takes time to precipitate, silently, and has an impact on the living beings of the entire earth.

Although he has not mastered the law of wood and the law of creation for the time being, he believes that in the near future, the law of earth wood will definitely be mastered by him, and then he can regulate the oxygen content on the earth as he likes.

"The thickness of the atmosphere is 500 kilometers less." Wu Jiaoyang sensed it and found that after all the dust was removed, the thickness of the earth's atmosphere was directly reduced by 500 kilometers, leaving only about 1,000 kilometers.

But even so, the thickness of the atmosphere has doubled compared to before the asteroid was captured!

The atmosphere is the first layer of protection for the earth, and the meteorites that hit the earth every day are at least thousands, but these meteorites, unless they are particularly huge and slightly smaller, will evaporate directly in the sky after rubbing with the atmosphere, and will not have a slight impact on the living creatures on the earth.

In the past, meteorites with a diameter of 80 kilometers could directly bombard the earth's surface, but now that the thickness of the atmosphere has been doubled, the earth's atmosphere can naturally defend against all meteorite attacks with a diameter of less than 200 kilometers.

"Although it has increased by 500 kilometers, it is still far from my goal." In Wu Jiaoyang's mind, the Zhou Tian Star Array left by Pangu flashed, and all the stars in it were under the zenith, and the so-called zenith was only the outer part of the atmosphere of the Flood Desolate Continent.

After Wu Jiaoyang sighed, his eyes shifted to the earth, at this time, the temperature on the earth, near the equator, has approached 50 degrees, the air is like a steamer, because it is too hot and distorted, ordinary people in the high temperature, it is simply miserable, it is difficult to breathe, and it feels like it is about to suffocate, even if you look for the river to enter it to cool down, but the water temperature in the river is not low, it is like a sauna in it.

Even in areas close to the poles, the temperature at this time is about to reach 20 degrees, the glaciers of the two levels have begun to melt, and the permafrost of the extremely cold land has also begun to melt and become swamps.

Under the frozen soil, some prehistoric life, which was frozen instantly, began to slowly wake up when the frozen ground began to melt, causing slight earthquakes to occur in the surrounding land.

"You'd better stay under the permafrost." Wu Jiaoyang's gaze looked at the giant animal that was like a mountain range and had a body length of more than three kilometers, and his voice was cold.

"Chaos Chill."

In the embryo of the world, in the Taiyin Stars, two lumps of ice with a diameter of ten meters and a jade-colored luster were taken out by Wu Jiaoyang.

Just appeared in the real world, around the ice cubes, the air was extremely cold, turned into colorful ice blocks, and the surrounding space, because it could not withstand the cold wave that could freeze the space, like a spider web, began to crack.

"Shattered!" Wu Jiaoyang spat out his voice, and the two cold ice balls instantly shattered into thumb-sized fragments, although the cold intensified, the cobwebs that spread in space stopped expanding and soon disappeared.

"Go!" These thumb-sized pieces of chaotic ice disappeared from Wu Jiaoyang's hands, and a very small amount of cold ice fell to all parts of the earth, instantly forming icebergs that were extremely cold.

Most of the chaotic ice fell to the poles of the earth, and the extremely cold wave was released from it, instantly stopping the melting trend of the glaciers at the poles, and at the same time, the cold wave that spread wildly directly froze all the water molecules in the air and fell on the glacier.

The surrounding sea also began to freeze rapidly, extending directly for hundreds of miles.

The temperature of the earth as a whole, after Wu Jiaoyang threw the chaotic cold iron, began to stop growing, and quickly began to decline to the extreme, in the country of the dog and bear in the north of the Dragon Country, directly from summer to cold winter in an instant, goose feathers and heavy snow turned the entire sky into a snow-white.

The people of the bear country began to sweat profusely, the weather changed suddenly, the temperature dropped, and they directly entered the cold winter, and they couldn't take precautions, they shivered from the cold, and quickly ran to the house, putting on the thickest warm clothes to resist the lower and lower temperatures.

Although in countries close to the poles, people are frantically scolding their mothers after facing the sudden change in the weather, but at this time, there are almost nine layers of people on the earth, cheering wildly.

"Chaos Ice! The handwriting of the incarnation of the Heavenly Dao is really not comparable to us. "Supreme Dao Lord, intercepted a piece of Chaos Ice, the extreme cold wave contained in a piece the size of a thumb, if it is released instantly, it can even freeze everything within ten kilometers of the surrounding area, even if it is a saint-level existence, it will not be able to escape the cold of Chaos Ice that freezes everything, and it will be frozen for a period of time.

This is not a quantitative gap, but an absolute qualitative gap.

"Chaos Ice, the innate top-level refining material, is the best material for refining the acquired spirit treasure, in the time of hundreds of millions of years in the Flood Desolate Continent, a total of three times have been born, and each time it was born, it was only the size of an egg." The Tongtian Dao man also intercepted a piece of Chaos Ice in his hand, if it weren't for the hindrance of the Supreme Dao Lord, he would even want to directly take all the Chaos Ice that fell to the ground into his own hands.

Because in the previous life, every appearance of chaotic ice would bring endless bloody rain, not to mention ordinary cultivators, even quasi-saint-level powerhouses would participate in the competition.

Moreover, the innate level refining material of Chaos Ice, the refined acquired spirit treasure, can easily return to its roots and turn into a terrifying innate spirit treasure.

"The Heavenly Dao incarnation is really generous, and I don't know what kind of reward we will receive for the immeasurable merit we have obtained by helping sentient beings." At this time, even if she is as indifferent as Nuwa, after seeing Wu Jiaoyang's generosity, she is also looking forward to the rewards she will receive after saving sentient beings.
