Chapter 2918: Planetary Transformation

This planet looks lifeless, the ground is full of dead silence, there are no plants, let alone animals, but there is an atmosphere and water, and the position from the stars is also very suitable, which has the conditions for the evolution of life.

Needless to say, those silicon-based creatures or other creatures in science fiction are all imagined by human beings, and no one knows what kind of planet they are suitable for living on.

According to human's own experience, of course, now humans can only judge based on this. After all, humans have never seen aliens, so they don't know what they are like.

From the perspective of human beings, the size of a planet suitable for living must be appropriate. Too small gravity will not hold the atmosphere, and too large will cause other problems; and it must be a solid planet, and a gas planet like Jupiter is definitely not suitable; and the distance from the star. It can't be too far away, it's too cold, and it can't be too close, it's too hot.

Moreover, the orbit must be regular. Planets like the Trisolaran system, which may cause catastrophe at any time, may hardly be able to give birth to civilizations. Even if life can be born, there is not enough time for them to evolve civilizations.

There must also be air and water, which are necessary conditions for the survival of humans and other mammals, and the current week basically meets the above conditions, with both air and water, not far or near the position of the stars, and the temperature difference between day and night is just within the tolerance of human beings. Within the range, the atmosphere actually contains oxygen.

Shen Long took out the adaptive light and irradiated himself and Arya, and then landed on a high mountain on the surface of the planet, overlooking the surface of the planet. At least from the surface, there are not many large craters on this planet. After all, there is an atmosphere, and a lot of meteorites will be burned when passing through the atmosphere, which protects the safety of this planet to a certain extent.

"Let's take a look at the composition of the planet's atmosphere first!" Shen Long took out an instrument to test, and found that the atmosphere is mainly carbon dioxide, nitrogen and oxygen? It's just that the distribution ratio is different from that of the earth? The concentration of carbon dioxide is much higher, and the concentration of oxygen is much higher. Much less? Can't breathe at all.

After testing several oceans on this planet? After analysis, it was found that the water quality here is quite similar to that on the earth? It's just that there are no living things in the water, not even microorganisms, bacteria, and viruses.

Without the existence of life? Shen Long will not have much moral pressure after transformation? He first took out the seeds of fast-growing cyanobacteria and threw them into the ocean. Photosynthesis and oxygen release; its development makes the entire earth's atmosphere develop from anaerobic state to aerobic state, thus giving birth to the evolution and development of all aerobic organisms? If there are no cyanobacteria? There will be no so many life on the earth in the future.

It is even more impossible for human beings to exist. Until now, cyanobacteria are still responsible for most of the functions of oxygen circulation on the earth. The tropical rainforest, which is called the lung of the earth, is far inferior to the function of cyanobacteria in supplying oxygen to humans.

If it evolves as normal in the history of the earth? I am afraid that humans will be able to colonize alien planets, and the blue algae released by Shen Long just now have not changed the atmosphere of this planet to a ratio that humans can live in.

But with Shen Long’s handicap? It’s completely possible to accelerate, and I saw blue algae spread out quickly on the sea surface? It didn’t take long to cover the entire ocean. These blue algae absorb carbon dioxide, release oxygen, and fix nitrogen in the atmosphere? No cost How much time, the atmosphere of this planet can already breathe directly.

"Okay, this is the first step, and then we can plant more plants!" The evolution process of life on earth is much more complicated, just read the "4.6 Billion Ensemble of Evolution" in just a few words. I know, but Shen Long doesn't intend to completely copy the evolution process on Earth.

Planting cyanobacteria just now is equivalent to fast-forwarding the earth for hundreds of millions of years, so let’s let this planet continue to fast-forward hundreds of millions of years now. Shen Long skipped the long process from bacteria to single cells, and then from single cells to complex life , directly transformed the soil, and began to plant the magical plants that he had collected from various mission worlds on this planet.

Ginseng fruit trees and laurel trees in "Journey to the West"... Whomping willow, screaming grass, fluttering bushes, mandrakes in the world of "Harry Potter"...the fairy grass brought back from "The Legend of the White Snake" The sacred tree, the heart-shaped grass brought back from Wakanda, and the plants brought back from other worlds that do not exist on the real earth.

Of course, he didn't forget about Arya, he planted the seeds of the heart tree in the world of "A Song of Ice and Fire" near the North Pole of this planet, and then Arya stood there blankly, watching this A familiar plant, also known as a weirwood, sprouted rapidly before her, spreading thick branches and producing red, palm-like leaves.

Arya walked slowly over to the largest weirwood, drew her Valyrian steel dagger, and began to carve a human face into the tree.

Then he looked back at Shen Long, "I want to rebuild Winterfell here! It's the same as the one I lived in back then!"

"No problem, we can even finish this work ahead of schedule!" For Shen Long, this matter was easy. He asked Bai Ze to find the blueprint of Winterfell from the database, and then use Doraemon's props to summon A group of robots, let Bai Ze control them, and build Winterfell City according to the drawings.

Shen Long chose to build this castle next to the weirwood forest. He even found a hot spring, just as it was written in the book. Two thick city walls and a village located at the gate surrounded the castle, covering an area of ​​several acres. complex of huge castles.

Inside the city walls, the castle is made up of a large number of courtyards and small open-air spaces. People practice martial arts in these schools. The inner courtyard is another place for practicing bows and arrows. It is located next to the ruined tower. Arya used to Archery is practiced here, while the main keep and halls are located within the inner keep in the center of Winterfell.

The main castle is the fortress core of the entire castle building. It is built on a natural hot spring to keep warm. The walls are made of granite. The entire campus has a panoramic view.

The hall is a family dining place for entertaining guests and the owner of the castle. The outer wall is made of gray stone and hung with flags. There is a gate made of oak and steel facing the castle yard, and there is another There is a side door in a dark corridor; the interior of the hall can be filled with eight long tables, separated by the middle corridor, with four tables on each side, which can accommodate 500 people, and the seats on the high platform are prepared for noble guests.

Arya watched, her eyes slowly getting wet.
