Shepherding Humanity (Nurturing Humanity)

There was a huge red fireball close at hand in the sky, and fire snakes were rolling wildly. The solar flares were rolling in a tidal bright red, which was more magnificent than the ten days in the fairy tale.

The ground was bright red.

A dark and slender mechanical battle armor stood quietly on the desolate crater ground, and the rocks on the ground were baked red.

"The heat and radiation of this solar energy are much cooler than the solar energy on the earth. With this intensity, I am afraid that it will be directly irradiated and killed instantly, the skin will fester, and the cells will collapse." Xu Zhi had nothing to do, quietly Look at the sky, after all, this is the closest place to the sun.

At this time, in the test field within the body, the ancient tree of star elves is multiplying 10,000 times like crazy.

Using your own inner world to test evolutionary species is the best way.

After all, it was natural to find a biological test field in other places at any time before, but what about the vacuum environment now? Where to test? The nine-turn Xuan Gong in the body is the only choice.

La!

Soon, the ancient elf trees multiplied rapidly, green and lush, and full of vitality, but they were just seedlings. It would take some time to grow into the eleven elf eternal mother trees.

"Reduce air concentration by 50%."

Xu Zhi raised his eyebrows slightly.

wow——

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

The air is thinning, after all, it doesn't take so long to progress gradually, and it will be a mass extinction as soon as it comes up.

Soon, with the decrease in air concentration, the oxygen and carbon dioxide in the air dropped sharply, and there began to be a large number of ancient star tree seedlings, unable to withstand such an environment, and gradually withered, withered, and died. The seedlings of the ancient trees survived and developed their own mutations.

They gradually became dark green, and began to greatly reduce their metabolic capacity, requiring less gas!

The old species that could not survive the changes in the living environment quickly became extinct, and new species began to reproduce, which fully reflected the natural selection of things and the survival of the fittest.

"Reduce demand? Treat the symptoms, not the root cause."

Xu Zhi shook his head and pumped again, thinning the air again.

This time, the plants are completely dead.

The gas concentration at this moment, no matter how to reduce its own demand loss, is not enough to maintain the survival of plants. These plants have finally started to go extinct in large numbers, and they don't even have the attitude to survive!

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

once.

twice

The days of experimenting and evolving species are always very boring, just like the lava field in the past. It went extinct again and again, I don't know how long it took.

In the plants, a touch of greenness appeared again.

This is a dark green plant. It has two pea-like cavities in its body, which store oxygen and carbon dioxide from the outside world, and compress them in the two cavities to increase the density of the required gas.

Start to save air.

Just like animals store energy, fat.

Just like a baobab tree's stomach stores a lot of water.

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

"The inner loop has begun."

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

Plant parts produce oxygen and absorb carbon dioxide! Animal parts produce carbon dioxide and absorb oxygen! The two sides complement each other and form a simple ecological cycle of animals and plants. "

Another good time passed.

An unexpected and bizarre evolutionary phenomenon appeared.

Because the air in the entire space is limited, and the gas storage capacity in their bodies is also limited, oxygen and carbon dioxide have become extremely rare resources in this vacuum environment.

Some plants actually began to grow hands and feet, and the bark turned into a half-human, half-plant flesh-and-blood form, and began to snatch the air in other plants.

Boom!

The two funny and weird little tree people collided fiercely, rolling slowly on the ground.

Huh, Huh!

They were smoking all over, like steam men.

"???"

Xu Zhi was startled on the spot. It was the first time that the tree itself had become unruly in the course of evolution.

But after thinking about it, he woke up again,

"Because the ancient stars and trees breed tree elves, they are naturally the route for the evolution of elves with human genetic bodies. It is because they want to grab air and compete for natural selection."

While Xu Zhi was stunned, one tree knocked down another tree, grabbed the other's two cavity bags of oxygen and carbon dioxide, and ate them!

All of a sudden, my stomach bulged, very satisfied.

"Eat air?"

Xu Zhi was stunned, "Okay, a very special vacuum species."

After a while, these plants scrambled for each other, stored in their stomachs, and killed each other until only a small part was left.

"Interesting." Xu Zhi pondered for a while, then picked up the notebook to record, "Air, restricting their population is too small, the population is insufficient, and it is difficult to carry out new evolution."

Xu Zhi thought for a while, and then returned the air to them.

With the increase of air, those plants have enough self-demand, and they have filled the two cavities. They have no desire and no desire, and begin to produce offspring, and supply air to their offspring.

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

Some plants have gradually taken on the form of elves, and are evolving into handsome human-shaped tree elves, with legs, hands, and emerald green hair.

Their roots have turned into a long and soft monkey tail, which can take root on the ground when they are not moving, and perform the role of a tree.

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

"This is so fun!"

Xu Zhi felt very pleasantly surprised, "Two air-chamber hearts, one oxygen heart, and one carbon dioxide heart, form an ecological circle within myself, very self-isolating, unless the gas leaks out, there is no need to worry in a vacuum."

"Take a breath, live a lifetime, the best diver in history."

"These plants have no blood vessels, although plants have no blood. But the trachea replaces the blood vessels to circulate the whole body, which is so special!"

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

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

Xu Zhi looked at it, and his face became completely strange, "It can run and jump, it seems that the air flow in the blood can contain energy, transport energy, and form a special extraordinary vacuum universe life. However, this is not what I want. !"

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

Similar to the ancient tree of stars, it is a kind of tree spirit that obediently stationed on the ground, absorbs sunlight and radiation, bears energy fruit, and selflessly dedicates energy.

And this group is obviously to make itself stronger, to supply energy only to itself, to plunder everywhere, and it is very "selfish".

"The first vacuum species has completely gone astray. A tree can still run, but the unexpected potential is huge but it's useless to me now!" Xu Zhi thought about it, but let it go, "Throw it outside. Let them try to survive and adapt to the radiation and cosmic vacuum."

He casually threw them onto Mercury, let them fend for themselves, planted a batch of ancient stars trees, and re-experimented.

This time he learned well.

After they have evolved two cavities to store gas and are ready to start fighting, they immediately increase the concentration of oxygen and carbon dioxide to send 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 well-behaved tree, continued to take root and sprout, and desperately used two "cavities" to absorb the gas in the air, becoming stronger and stronger.

"It's done."

Xu Zhi took a closer look, this time the internal structure of the tree was different.

They are not like those humanoid plants, which have dense biological meridian blood vessels resembling two hearts, but two plant cavities that normally store gas circulation.

"Successful self-circulation, there is no need for gas, it is still the ancient star tree, the next step is to throw it outside to adapt to the vacuum radiation environment." Xu Zhi smiled and directly opened up the outside world of Fentian, connecting to the real space.

Whoa!

Under the huge scorching sun.

Trees began to wither rapidly, and they couldn't stand the heat and the pressure of a complete vacuum.

The most difficult living environment has survived, and it will not take much time afterward. After the mass extinction, some plants survived, successfully survived, took root on the ground, and completely formed an ancient star tree that can survive in a vacuum.

Plants that can live in the universe.

Before, the genes of the ancient elves began to rapidly absorb the power of radiation and stars, and the trees became more and more green and rotten.

"Finally done."

Xu Zhi smiled full of surprise, "It's almost the end."

The No. 1 power station was established. This solar power station continued to supply him with energy, and his realm was bound to advance by leaps and bounds!

In the future, the creatures that rely solely on the sand table will no longer be extinct.

Sure enough, greening the world and farming everywhere is the most satisfying.

At this moment, he was eager to plant the entire planet.

"It's just that the limitation is very big. After all, it is not a real vacuum species, and it still needs gas. With my current knowledge, it can only be like this." Xu Zhi took a deep breath, "Also, their gas circulation, once broken and leaked, will die. Even if it is not damaged, plants need not only air, but also water!”

After all, a plant is heat-resistant and has a strong ability to store water, but it still needs water, which is bound to be lost.

Where does the water come from?

Know that Mercury has no water.

"I still have to water myself." Xu Zhi felt that he was going to be speechless.

It's so hard.

Do you want me to water a tree?

He suddenly agreed that the trees of those players were serious trees and would water themselves.

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

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

Xu Zhi kept sorting out his thoughts, "But I'm also prepared. Another teleportation array will come from Ermin, and I'll wait for the power station erected here to facilitate going back and forth and watering regularly."

Really become a farming stream.

Greening the desert planet environment starts with me.

"Let's plant 10,000 seeds first. Let's improve the variety first." Xu Zhi thought about it, he was not afraid that others would see it here, after all, he already had the means to block prying eyes.

And 10,000 pieces are estimated to be less than 100 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 and trees in the inner space, and they began to grow together, growing out one by one, and came to the vacuum of Mercury, while he silently provided water.

Soon a place was greened.

"In this case, it is estimated that it will take a day or two to evolve in Mercury. It has now evolved a rough embryo. When it fully matures, some details of energy utilization will be better."

Xu Zhi looked at these trees on Mercury indifferently.

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

As for the development of a sand table and the reproduction of a vacuum extraordinary civilization?

Mercury is impossible.

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

Self-inflicted, no need to manage and waste more effort.

But when Xu Zhi quieted down, he noticed that the pile of elves beside him had already multiplied very quickly and were alive and kicking.

Eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!

They were everywhere in the cracked crater, running and shouting, very happy, which surprised Xu Zhi, this was a vacuum environment.

But he soon turned black.

Because these guys ran to grab the water of those ancient stars and trees, obviously, they are destined to die here without water.

Moreover, they also go to gnaw on those trees to obtain nutrients and energy, and they also fight with each other. They are very belligerent and have a heavy heart for killing.

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

"Forget it, let these air elves jump around here a little more and evolve to adapt to the vacuum environment." Xu Zhi thought for a while, "When I leave, I will take them away, after all, they cannot survive here and will be thirsty. dead."

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

Undoubtedly, the potential is great.

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.

"Also, 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. As long as they get one of them, they can be re-transformed and replenished." Xu Zhi smiled. , "It's the perfect vacuum cell race I've created so far."

"It's just that, after a random farming trip, I went back with a bunch of little guys. When these guys are brought back, where will they be raised?"

Xu Zhi was bored, so he began to sit on the spot, watching the evolution of the trees, teasing the air elves, and felt a little weird, "Wait, he has a tail, is belligerent, likes to fight, and can also use his air to sense. Qi. Could it be the legendary Saiyan, the first fighting race in the universe?"

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

Eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!

The child struggled cutely and struggled.

Xu Zhi relaxed slightly, and the child hurriedly ran to the back of a huge gravel crater.

"No, Saiyans can't survive in a vacuum, and the one with the tail may also be the emperor of the universe, Frieza." He had nothing to do, wearing a mechanical armor, full of thoughts.

But he was suddenly slightly startled, and he sensed the space in his body, "I didn't expect that Yundi, this person, actually brought a heavenly person, sensed Fentian, and was about to come?"

He hesitated for a while, but didn't stop him. "It's boring to stay here anyway. Why don't they come to Mercury, a mysterious universe? Look at the vacuum environment, these ordinary creatures can't bear it!"

"Wait." Xu Zhi's eyes lit up, looking at the sun in the sky, it turned the earth blood red, and there were craters everywhere, "A battlefield of ancient myths?"

He felt idle and idle, and it was time to complete some settings.
