There was a huge red fireball hanging in the sky, fiery snakes were rolling wildly, and the flare of the sun's atmosphere was rolling a tide-like bright red, which was even more magnificent than the ten days in the mythical story.

The ground is red.

A long, dark mechanical armor stood silently on the desolate crater ground, the rocks on the ground roasted red.

"The heat and radiation of this solar energy is much cooler than that of solar energy on earth... This level of richness, I am afraid that below the Emperor of Heaven, will directly and instantly radiate to death, the skin will ulcerate, and the cells will collapse..."Xu Zhi had nothing to do, looking at the sky quietly, after all, this is the closest place to the sun.

At this time, in the experimental field in the body, the Star Elf Ancient Tree was frantically multiplying ten thousand times.

The best way is to experiment with evolutionary species in your own inner heaven and earth.

After all, in the past, it was natural to find a biological test field in other places at any time, but now what about the vacuum environment? Where to go to test? The Nine Turns Xuangong in the body is the only choice.

Hoo!

Soon, the elven ancient trees multiplied rapidly, green and vibrant, but they were only seedlings, and they didn't know how long it would take to grow into the eleven eleven eleven eleven elbow eternal mother trees.

"Reduce air concentration by 50%. ”

Xu Shi raised his eyebrows slightly.

Wow –

In an instant, a large amount of air was sucked away.

The air was thinning, and Xu Paper didn't take so long to step by step, and it was a mass extinction as soon as it came up.

Soon, with the decrease in air concentration, the oxygen and carbon dioxide in the air decreased sharply, and a large number of ancient star tree seedlings began to wither, wither, and die gradually after enduring.

They gradually turn dark green and begin to significantly reduce their metabolic capacity, requiring a lower amount of gas!

The old species that could not survive the changes in the living environment quickly became extinct, and new species began to reproduce, fully embodying natural selection, the survival of the fittest, and soon the whole land was a new population, and the whole land was green.

"Reducing demand? ”

Xu Shi shook his head, and twitched again, thinning the air again.

This time, the plants were completely gone.

The concentration of gas at this moment, no matter how much it reduces its own demand loss, is not enough for the survival of plants, which have finally begun to be extinct in large numbers, and even have no posture of surviving at all!

"It's completely gone, try again, I guess this time it's going to drop too fast, and I don't have enough time to adapt. Xu Paper habitually picked up the pen and paper and recorded some, "Next time, slow down and reduce the air concentration." ”

Once...

Twice...

The days of experimenting and evolving species are always boring, just like the lava fields of the past... Extinction again and again, I don't know how long it has been.

In the plants, a touch of greenery appeared again.

It is a dark green plant with two cavities like peas, which store oxygen and carbon dioxide from the outside world, respectively, and compress them into two cavities to increase the density of the gas demanded.

It's starting to store air.

It's like animals store energy, fat.

It's like a baobab tree has a belly that stores a lot of water.

At the same time, it is gradually moving towards equilibrium, balancing the respiration and photosynthesis of the two cavities, so that oxygen and carbon dioxide form an internal circulation in the body, and no longer need external supply.

"It's time to start the inner loop. ”

Xu Zhi's eyes widened and he took a deep breath, "Self-produced and self-sold!" Let oxygen and carbon dioxide circulate in the body, which is equivalent to the combination of plants and animals.

Plants produce oxygen and absorb carbon dioxide! Animals produce carbon dioxide and absorb oxygen! The two sides complement each other, forming a simple ecological cycle of animals and plants. ”

After a long while, a strange evolutionary phenomenon that I didn't expect appeared.

Since the air in the entire space is limited, and the amount of gas stored in their bodies is also limited, air has become an extremely rare resource in this vacuum environment.

Some plants began to grow hands and feet, and the bark turned into a half-human, half-plant flesh form, and began to rob other plants of the air in their bodies.

Bang!

The two funny little tree men collided violently and rolled together on the ground.

Huha, Huha!

They were covered in smoke, like steam people.

“？？？”

Xu Zhi was shocked on the spot, it was the first time that the trees themselves had taken the initiative to become indecent in their evolution.

But when he thought about it, he came to his senses again,

"Because the Ancient Trees of the Stars, the Tree Elves that reproduce, they naturally have human genetic forms... The route of the evolving elves in front of them is because they want to grab the air and compete for natural selection. ”

In Xu Zhi's stunned, a tree knocked down another tree, grabbed the other party's oxygen and carbon dioxide two cavity bags, and ate them!

All of a sudden, my stomach bulged and I was very satisfied.

"Eat air?"

Xu Shi was stunned, "Okay, it's a very special vacuum species." ”

In a short time, these plants, snatching each other and storing them in their stomachs, fought each other until only a small part remained.

"Interesting. Xu Shi pondered for a moment, picked up his notebook and recorded, "Air, restricting their population is too small, and the population is not enough to carry out new evolution. ”

Xu Shi thought for a moment, and then returned the air to them.

As the air increased, the plants had enough self-demand to fill the two cavities, and began to produce offspring and supply air to the offspring.

Then, as the population increased, the air began to run out again, and they began to fight each other again, and they ushered in a new evolution!

Some plants gradually took on the form of elves, evolving into handsome humanoid tree elves, legs, hands, and emerald green hair.

Their roots turn into a long, soft monkey tail that can take root in the earth when it is not moving, fulfilling the function of a tree.

The body became extremely complex, and the two cavities began to turn into two hearts, connecting the air meridians that extend in all directions, just like the structure of human blood.

"That's so much fun, isn't it?"

Xu Zhi felt very pleasantly surprised, "Two air cavity hearts, one oxygen heart, one carbon dioxide heart, forming an ecosystem in the body, very self-contained, unless the gas leaks, otherwise there is no need to worry in the vacuum..."

"These plants don't have blood, even though they don't have blood in the first place.... Can trachea, replace the vascular circulation of the whole body, this is too special!"

However, it is also a matter of course that in a vacuum, air is a precious storage resource, as precious as blood!

In addition, the air flow begins to carry some nutrients in the dense and complex meridian circulation in the body, gradually replacing the role of blood.

Xu Zhi's face became strange, "It can run and jump, it looks like the air flow in the blood, which can contain energy, transport energy, and form a special extraordinary vacuum cosmic life.... But that's not what I want!"

His original intention was to create a group of solar-powered trees.

Like the ancient trees of the stars, they obediently stand on the ground, absorb sunlight and radiation, bear energy fruits, and selflessly dedicate energy...

And this one population is obviously to make itself stronger, and the energy is only supplied to itself, plundering everywhere, which is very "selfish".

"The first vacuum species, completely off-track, a tree can still run, but the unexpected potential is huge... But it's useless to me now!" Xu Zhi thought about it, but still forgot it, "Throw them into the vacuum outside, let them try to survive and adapt to the radiation and cosmic vacuum environment." ”

He threw them on Mercury, left them to fend for themselves, and planted a batch of ancient trees to experiment again.

This time he learned to be obedient.

After they have evolved two cavities to store gas, they are ready to start fighting, immediately increasing the concentration of oxygen and carbon dioxide to bring their food to their eyes, preventing them from growing legs and competing for the storage capacity of other plants.

Sure enough, this time, their route did not grow legs, but still became a good tree, continuing to take root and sprout, desperately using two "cavities" to absorb the gas in the air, becoming stronger and stronger.

"It's done. ”

Xu Zhi looked carefully, and this time the internal structure of the tree was different again.

They are not like those humanoid plants, which have dense biological meridians that resemble two hearts, but two plant cavities that normally store gas circulation.

"Successful self-circulation, no need for gas, it is still an ancient tree of stars, and the next thing is to throw it outside and adapt to the vacuum radiation environment. Xu Shi smiled, directly opening up the outside world of the burning sky and connecting the real space.

Crash!

Huge scorching sun.

The trees began to wither rapidly, they could not withstand the heat and the pressure of the total vacuum.

After the most difficult living environment, it took not much time after that, and after a large number of extinctions, some plants survived the fittest, successfully survived, took root in the earth, and completely formed an ancient star tree that can resist the survival in the vacuum.

A plant that can survive in the universe.

And before, the genes of the elven ancient trees began to make them quickly absorb the power of radiation and stars, and the trees became more and more verdant and green, which was very rotten.

"It's finally done. ”

Xu Zhi smiled with surprise, "It's almost coming to fruition." ”

The No. 1 mass extinction power station was established, and this solar power station continues to supply him with energy, and his realm will inevitably advance by leaps and bounds!

In the future, I will no longer rely solely on the extinction of creatures in the sand table.

"It's just that the limitations are huge... After all, it's not a real vacuum species, and it still needs gas, and with my current knowledge, that's all I can do. Xu Zhi took a deep breath, "And, their gas circulates inside, and once it is broken and leaked, it will die... And even if it doesn't break, the plant needs not only air, but also water!"

After all, no matter how heat-tolerant a plant is, it still needs water, which is inevitably depleted.

Where does the water come from?

You must know that Mercury is without water.

"I still have to water it myself. Xu Shi felt speechless.

It's so hard.

And Mercury is the best solar environment, close to the sun, the strongest radiation, after all, if you go to Venus, not only is the radiation much lower, but there is no liquid water.

"It seems that my idea of greening the solar system is unrealistic. ”

Xu Shi kept sorting out his thoughts, "But I am also prepared, and I will flicker a teleportation array from Ermin, and wait for the power station to be set up here, so that it is convenient to go back and forth, and water it regularly." ”

It really became a farming stream.

Greening the desert planet environment starts with me.

"Plant it 10,000 first.... However, let's improve the varieties first. Xu Zhi thought about it, he was not afraid that others would see this, after all, they had already had the means to shield peeps.

And 10,000 pieces, it is estimated that it is not even a hundred acres, how big is a planet?

Even if you don't block it yourself, it's hard to find out.

He began to quietly look at these ancient stars in the inner space, and began to grow, one by one growing outside, to the vacuum of Mercury, and he was silently providing water sources.

Soon a place was greened.

"In this case, it is estimated that it will take a day or two to evolve in Mercury and so on, and it is now evolving into a rough embryo, and when it completely evolves and matures, some details will be better. ”

Xu Zhi looked at the trees on Mercury very indifferently.

He came here to build a power station and provide himself with a channel for energy sucking.

As for the development of the sand table and the reproduction of extraordinary species?

Mercury is out of the question.

This is destined to be a barren energy power station, and it is the best choice to come and water and grow vegetables every day.

Fend for yourself, don't worry about it and waste more mental energy.

But when Xu Shi quieted down, he noticed that the bunch of elves next to him had multiplied very quickly and were jumping around.

Babble!

They were running and shouting in the dry craters everywhere, which surprised Xu Zhi, this is a vacuum environment...

But his face soon darkened.

Because these guys ran to grab the water of those ancient trees of the stars, it was obvious that they were destined to die here without water.

In addition, they also gnaw on those trees, obtain nutrients and energy, and fight each other, very belligerent, and have a very murderous heart.

Xu Zhi immediately drove them all away, and wanted to shoot them to death directly.

"Forget it, let these air spirits bounce here a little more, and evolve to adapt to the vacuum environment. Xu Zhi thought for a moment, "When I leave, take them with me, after all, they can't survive here, they will die of thirst." ”

As for how to accommodate these unexpected surprises, it is a problem.

Undoubtedly, there is a lot of potential.

If they only need water to live and float in the universe, it will be very powerful, because there are still a lot of water resources in the universe.

"And, even if their two hearts are ruptured and the 'blood' in the internal circulation leaks, they can go to some planets to replenish carbon dioxide, oxygen... As long as you get one of them, you can retransform and complete. Xu Zhi smiled, "It's the perfect vacuum cell race I have made at present." ”

"It's just that after a random farming trip, there are a group of little guys when I go back, and after these guys are brought back, where will they be raised?"

Xu Shi was bored, so he began to sit in place, watching the evolution of those trees, teasing those qi elves, and felt a little weird, "Wait, with a tail, warlike, love to fight, and use qi.... Induction gas... Could it be the legendary Saiyan, the first fighting race in the universe?"

He stretched out his hand and lifted a child with a tail in the air, "Wukong, is that you?"

Babble!

The child was cute and struggled.

Xu Zhi relaxed slightly, and the child hurriedly pulled out his legs and ran, running to the back of a huge gravel crater.

"No, Saiyans can't survive in a vacuum, and the one with a tail could also be the Emperor of the Universe, Frieza. "He's idle, he's wearing a mechanical armor, and he's full of thoughts.

But he was suddenly slightly startled in front of him, and sensed the space in his body, "I didn't expect that Emperor Yun, who was actually taking a celestial man, sensed the burning sky, and was about to come over?"

He hesitated, but he didn't stop it, "It's not fun to stay here anyway, why don't they come to Mercury, a mysterious secret realm of the universe? Look at the vacuum environment, can these ordinary creatures withstand it!"

"Wait. Xu Paper's eyes lit up, looking at the sun in the sky, shining the earth into a blood-red color, and there were craters everywhere, "Make an ancient mythological battlefield?"
