The Dead Sea is the only place on the Death Star that has the word 'sea' in it, and there is no water in the sea, but a large amount of fine gravel. These tiny pieces of sand, a few pieces of sand gathered together, are not of much mass, but they take up a large area of space.

This caused the surface of the sand sea to be unusually soft, and if you stepped on one leg, you couldn't climb up.

Undead creatures without the ability to fly break into the sea of sand, whether it is a skeleton zombie or a lich, there is only one end, that is, to sink into the sea of sand until the soul withers and dies.

If you can still absorb the breath of death in the sea of sand and your soul will not wither, then congratulations, what awaits you will be eternal imprisonment.

Unless you're lucky enough to get to the point of flying, don't try to get out of trouble on your own.

After Zhang Qifan became the king of the Death Star, he once organized a large number of people to rescue those creatures that strayed into the Dead Sea, and then drove away all the undead creatures within 50 kilometers of the edge of the Dead Sea, and cleaned up the skeletons to prevent new souls from being born.

Since then, the Dead Sea has truly become the 'Dead' Sea, and with the exception of Rose, a quiet fellow, few undead creatures will penetrate deep into the confines of the Dead Sea.

After landing on the ground, Zhang Qifan led a large group of men to the edge of the Dead Sea, solemnly holding a fist-sized green seed in his hand, which was the seed of the tree man.

The environment of the Death Star is only suitable for the undead, but not for any race of life, whether it is a Nat or a human, don't think of going out into the wild without wearing protective clothing, the highly toxic air and radiation can kill the strongest humans in a short time.

However, many of the materials need to be produced by living species. Such as rubber, grain, wood, and so on. Therefore, transforming the environment of the Death Star is the first step in pioneering. Anyway, the undead are highly adaptable, and they can adapt to harsh environments, not to mention comfortable environments.

Transforming the planet's environment is what Treants do best.

The Death Star is just a harsh environment, and once upon a time, it was a colony star, and there was a lot of life living here. This means that the elements of the Death Star are abundant. Gold, silver, copper, iron, silicon, carbon, aluminum, magnesium, oxygen, nitrogen, etc., everything.

However, Ba Erxing is a primitive barren star, and ordinary barren stars have a characteristic. It is a single composition, such as a rock ball composed of a small number of elements such as ferrosilicon, or a water ball composed of pure hydrogen and oxygen.

Even a desolate star like Ba Erxing can be transformed into a primeval forest, let alone a Death Star. As for the above, it is a bad environment for ordinary people. It doesn't affect the Treants at all.

Holding the tree man seed in your hand. Zhang Qifan asked cautiously: "Is it okay to plant it like this?" ”

It's no wonder that Zhang Qifan would ask like this, his impression of plants was only formed when he was on Earth, and there were no plants in the previous Death Star.

All plants on the earth are fragile and delicate, and a sudden change in temperature can kill a large area, not to mention low temperatures and radiation and poisonous gases.

What if a seed is planted and dies? Zhang Qifan does not have a few such tree man seeds in his hands, and the seeds that a tree man can give birth to in his life are also limited. Yulia gave birth to these seeds and wanted to continue bearing them. It will be at least a few hundred years away.

Originally, the best way was to let Yulia take root directly in the ground and grow back into a real world tree, but Yulia already has an owner, and she is now obeying Zhang Qifan, completely because of the control device.

This is not the safest control device, and no one knows when something will go wrong with the control device. What about Yuria, who is already rooted in the Death Star by then? It's okay to continue to be obedient, but if you don't obey, you can only be ruined, and at that time, the Death Star will definitely be ruined.

The best way is naturally to plant a tree man by Zhang Qifan, from the moment of development, Zhang Qifan is the main one, and this kind of relationship engraved in the tree man gene is a little safer.

Hearing Zhang Qifan's inquiry, Yulia nodded in response: "Yes, the soil inlay here is a bit barren and has a single element, so it's best to mix it and promote germination." ”

"How?" Zhang Qifan hurriedly asked, is it too dry here, need more watering?

"It's good to find more different elements to pile nearby, iron, silicon, carbon, calcium, etc., the richer the elements, the better." Yulia said.

Zhang Qifan blinked, somewhat understood.

Several small transport planes made several trips, and a mountain of garbage was piled up on the edge of the Dead Sea.

The human fleet is a huge team of 500,000 people, and the number of Nats is also as high as 300,000, and these nearly a million creatures, the garbage they make every day is so terrible, pulling a small half is enough to fill the neighborhood.

In the past, all this garbage was sorted and recycled, but now that it is pulled over, there are really all elements here.

Seeing that it was ready, Zhang Qifan gently stroked the tree man seed a few times, and he could feel the yearning and expectation for life of the tree man seed, as if he couldn't wait for it to sprout.

As soon as his mind moved, the ground at Zhang Qifan's feet exploded, revealing a pothole-sized hole, putting the tree man seeds in it, filling the soil and burying it, and watering it.

These steps, from a human point of view, are quite normal, and with a little sunlight, the seeds will sprout quickly.

However, this is the seed of the tree of life. As the water soaked the ground, a few seconds later, the ground where the tree man's seeds were buried, the earth arched, and a green shoot slowly emerged.

After this green shoot emerged, it never stopped, growing and spreading at a speed visible to the naked eye, and soon the ground that had just been watered completely dried up again.

Seeing this, Zhang Qifan hurriedly signaled to continue watering.

In the universe, hydrogen and oxygen are very abundant, and water is an inorganic substance formed by the combination of these two elements.

Although the Death Star is arid, it was once a colony with life, and there is absolutely no shortage of water, it may just penetrate the earth, it may freeze and hide in the middle of nowhere, or it may evaporate into the air, or it can be reduced to hydrogen and oxygen.

Zhang Qifan didn't have time to explore, so he directly dragged an ice meteorite back in the asteroid belt.

The large amount of water poured through the wider area of the ground, and it looked like rain from a distance.

The green shoots grew faster, and although the green surface showed some signs of drying up under the erosion of radiation and poisonous gases, it did not affect its growth rate in the slightest.

The dry surface layer cracks open, revealing the tender green inside, and then dries and splits again, and after a few times, the bottom of the cracked surface layer is no longer tender green, but a rough texture that is almost the same as the color of the dry surface.

Obviously, Green Shoots is adapting to the harsh environment of this planet at a super fast speed.

But that wasn't the end of it, and it wasn't long before the green shoots spread to the garbage mountain. When its vine came into contact with a piece of scrap iron, the surface of the vine changed, extending countless roots and wrapping tightly around the iron.

Then the surface agitated a few times, and began to release transparent sap, which just stuck to the iron block, and immediately melted the iron at a speed visible to the naked eye, and then absorbed by the root system. (To be continued......)
