All Heavens Dragon System

The planet looks lifeless, the ground is full of silence, there are no plants, let alone animals, but there is an atmosphere and water, and the distance to the star is also very suitable, and it has the conditions to evolve 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.

According to human experience, of course, humans can only judge by this. After all, humans have never seen aliens and don't know what they are like.

From a human point of view, the size of the planet that adapts to survival must be appropriate. Too small gravity cannot retain the atmosphere, and too large will cause other problems; and it must be a solid planet. Gas planets like Jupiter are definitely not suitable; and the distance to the star It can't be too far away, it's too cold if it's far away, or it's too hot if it's near.

Moreover, the orbit must be regular. The planets of the Trisolaran galaxy that can cause catastrophes at any time may not be able to give birth to civilization. Even if life can be born, there is not enough time for them to evolve into civilization.

There must also be atmosphere and water. These are the necessary conditions for humans and other mammals to survive. This week basically meets the above conditions. There is atmosphere and water. It is not too close to the position of the star. The temperature difference between day and night is just in humans. Within the range, the atmosphere still contains oxygen.

Shen Long took out the adaptation light to shine on 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 the planet to a certain extent.

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

After testing several pieces of ocean on this planet? After analyzing, it was found that the water quality here is quite similar to that on the earth? It's just that there are no organisms in the water, not even microorganisms, bacteria, or viruses.

Is there no life? Shen Long has no moral pressure to transform? He first took out the seeds of fast-growing cyanobacteria and threw them into the ocean. Cyanobacteria are large single-celled prokaryotes that can carry out oxygen-generating photosynthesis. Photosynthesis and release oxygen; its development makes the entire earth's atmosphere develop from an anaerobic state to an aerobic state, thus giving birth to the evolution and development of all aerobic organisms? If there is no blue algae, there will not be as many life on earth in the future.

It is even more unlikely that humans exist. Until now, cyanobacteria are still responsible for most of the function of oxygen circulation on the earth. The lung tropical rain forest of the earth, as you call it, is far from the function of oxygen supply for humans and cyanobacteria.

If it evolves normally as in the history of the earth? I am afraid that when humans are able to colonize foreign planets, the cyanobacteria that Shen Long just released have not changed the planet's atmosphere to a proportion that humans can survive.

However, with Shen Long, it’s completely possible to accelerate, and I saw the blue algae spread out quickly on the sea surface. After a short while, they covered the entire ocean. These blue algae absorb carbon dioxide, release oxygen, and fix the 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 you can plant more plants!" The evolution of life on earth is much more complicated. Just look at the number of words in the "Evolution of 4.6 Billion". I know, but Shen Long does not intend to copy the evolutionary process on Earth.

Just now planting cyanobacteria is equivalent to fast-forwarding the earth for hundreds of millions of years, so 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 he collected from various mission worlds on this planet.

The ginseng fruit trees and laurel trees in "Journey to the West"...the beating willows, scream grass, flapping shrubs, mandela grass in the world of "Harry Potter"... the fairy grass brought back from "The New White Lady" The sacred tree, the heart-shaped grass brought back by Wakanda, and the plants brought back from other worlds that are not on the real earth.

Of course he did not forget Arya. He planted the seeds of the heart tree in the world of "A Song of Ice and Fire" on this planet near the North Pole. Then Arya stood there blankly, watching this A familiar plant, also known as fish beam, sprouts quickly in front of her, sticking out thick branches, and growing red, palm-like leaves.

Arya walked slowly to the front of the largest fish-beam tree, pulled out her Valyrian steel dagger, and began to carve faces on the tree.

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

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

Shen Long chose to build this castle next to Yuliangmu Forest. UU Reading www.uukanshu. He even found a hot spring. Just as it was written, two thick city walls and a village at the door surrounded this huge complex covering several acres.

Inside the city walls, the castle is composed of a large number of courtyards and small open 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 stump. Arya used to Practice archery here, and the main fort and hall are located in the inner fort in the center of Winterfell.

The main fortress is the core of the entire castle building. It is built on top of the natural hot spring for thermal insulation. The walls are made of granite, and are connected to the weapon depot through a closed bridge. You can see from a window on the bridge. The entire school field has a panoramic view.

The hall is used to entertain guests and the family dining place of the castle owner. The outer wall is made of gray stone and is covered with flags. There is a gate made of oak and steel facing the castle yard, and there is also a common entrance. A dark corridor has a side door; the inside of the hall can be filled with eight long tables, separated by a middle corridor, four on one side, can accommodate 500 people, and the position on the high platform is for the noble guests.

Arya watched, her eyes slowly getting wet.
