Although the general environment at that time was the effect of continuous photosynthesis of surface plants for thousands of years, according to common sense, even if the oxygen content in the air increased, it would not have much impact on the body size of the organisms for a while, but since the sky fell into the sea and the sea poured in, what can be measured by common sense?

Now, Fang Chen's only hope is that the increase in oxygen content brought by this qi wall is only temporary, and it will not cause large-scale biosphere mutations!

But the next day, he knew that this wish would not come true, because the concentration of oxygen content around him had increased to the point where it was visible to the naked eye, and when he opened his eyes, Fang Chen's eyes were a thin milky white mist, although with the sunrise, the white fog gradually dissipated, but the oxygen content in the air was still rising at a rate that could be checked on the surface of the body.

From feeling refreshed at the beginning, to now, as long as people sit in place, they can feel their bodies become light. Fang Chen stood up and tried it, and found that with the current oxygen content in the air, ordinary running and jumping would not even pant heavily, and simple sitting, lying and walking, one breath a minute was enough to provide the oxygen consumption needed by the body!

In just three days, Fang Chen's worst fears had happened, and the first to react to the increase in oxygen levels in the air was not animals, but the surrounding plants that were lying on the ground under the pressure of the air wall.

They are like drinking fairy water, the roots of the broken trees and vines, instantly grow and connect, in the blink of an eye is a lush forest, on the fourth day, these plants even gave birth to patches of aerial roots, looking from a distance, if they didn't see it with their own eyes, Fang Chen would think that what they saw in front of them was a primeval forest that had grown for thousands of years.

On the fifth day, large patches of moss began to appear on the ground, and as they walked in the forest, a white mist began to rise in the air, and on the afternoon of the fifth day, the aerial roots of these plants grew mouths!

Dark brown air roots kept wandering and swaying on the ground, like water snakes, constantly approaching and probing, looking at the big mouths on top of their heads, Chen Lin would not feel that these things were just a simple lack of playmates, and they ran over to make friends with them.

And their bodies also began to be affected by the heavy oxygen content in the air, all of them, almost all began to develop twice, they began to grow collectively, only one day, among their group, the shortest one exceeded 190, and one of them even began to return to his ancestors, but the direction of this atavism was a little speechless, and he began to grow body hair like crazy.

Every hour that passed, the man would run over to Chen Lin and ask for a fire bath!

On the seventh day, the size of the surrounding animals began to change visibly, and the ostriches they had seen on the bank of the river were now visible to Fang Chen running over their heads on long legs.

Looking at the footprints they left behind, Fang Chen's only good fortune was that these ostriches were vegetarians, but he also knew that those who passed over their heads could not all be vegetarians.

Half a month has passed, and the flying air roots in the surrounding forest have grown to waist thickness, and compared to the huge changes in the surrounding animals and plants, they are only more than two meters tall, which is not remarkable at all.

There are more and more air roots around, and after following them for half a month, they finally launched an attack on them, and the thick qi roots in a group rushed towards them with their mouths open and sharp fangs exposed!
