"Master, you remember that when you ordered me to make a sundial, some chaotic qi was left with me. You didn't dictate what to do with them at the time, and they've been stored near my roots for years. As you know, the pure chaotic qi is a highly fused pure energy, and my current essence is not as concentrated as theirs. So over the years, there have been a lot of leaks, and those leaked out of the chaotic qi they have not received your instructions. Some of them dissipate directly between heaven and earth. Some of them are like the seagrasses that evolved on their own at the beginning, some of them drifted into the sea and evolved according to the conditions of the sea, and some of them drifted on the land and evolved according to the land environment there. These chaotic qi eventually evolved into the most primitive animals. And these animals are evolving much faster than plants. ”

At this point, Patian added: "This is because their initial conditions are different from those of seagrasses, and seagrasses evolve very slowly because the environment was very harsh. Light, water, and minerals were all indispensable, and the constraints of the time could only evolve slowly. The animals start with a lot of oxygen and light, and the plants that spread all over the planet provide them with a huge amount of food. In particular, the animals that have just begun to evolve are herbivorous, with plenty of food and no natural predators, so of course they evolve rapidly. Only when the plants on the planet are not enough for the needs of all the animals, the animals that can't eat enough will evolve carnivorous systems, and the speed of evolution will slow down at that time. Judging from the natural death of plants according to the World Tree, there are still perfect enough conditions for animals to evolve for a long time. ”

After hearing this, Hongjun said to the World Tree, "Since there are animals, as their colonies grow, the consumption of oxygen will begin to increase, and then there will naturally be excess carbon dioxide for the plants to absorb. Let the rest of the chaotic qi divide half of it to continue to help the animals evolve, and the remaining half will still be stored with you. ”

"Yes master, do you need to go see the animals? There are also some species on this island, but they are all brought up from the sea by the waves. The World Tree said.

"Okay, tell Patian the location, I'll go over and have a look now." Hongjun knows that everything on this planet is sensed by the World Tree, but it is not good at guiding the position, so it is better to leave this matter to Patian to do it.

After that, Hongjun was led to the ground by the branches, and Hongjun thought that he should make something to walk around. It is difficult to swim across the sea, even if it is always inconvenient to go up and down the crown of the World Tree with branches every time.

When Hongjun slowly came to the position indicated by Patian, he saw a strip on the ground... Or is it one? It is always an earthworm-like creature, with the same body that looks like a circle, but the difference is that the creature is black and yellow, with a bulging front end, a slightly smaller back end, and a leaf-like thin slice on the tail. At the front of it is an organ that resembles a mouth, which appears to be a place for eating, and no other organs are visible from the outside. Important parts such as eyes and ears have not yet evolved. The creature seemed to have been washed ashore by the waves, and it was slowly squirming in the direction of the sea, trying to get back into the sea to which it had adapted. After ten minutes of viewing, the creature only moved a centimeter or two away. Just as I wanted to throw it into the sea, I thought of the knowledge of biological evolution that Patian had just explained to him. The outstretched hand was withdrawn. They are always trying to survive on this more promising land, and throwing them back into the sea with one more hand may eliminate the possibility of a species landing. "This is the largest species out there?"

"There are some bigger ones than this, but not much bigger, and now they're just getting used to being in the shallows." Patti's security department has read the memories of the World Tree, so there is an understanding of this as well.

At this time, in the direction of the World Tree, a thick, multicolored and mottled long pillar of light suddenly shot straight into the sky, rushing to a height of about three thousand meters before stopping, and when the subsequent pillars of light were all in place, it exploded and covered in all directions. Everywhere he passed, the sky drifted down with a silver light and sprinkled the earth. The creature in front of him seemed to have received this energy, and after a slight pause, the creature stopped squirming towards the nearby sea, but turned around and bit a seaweed leaf that had washed up on the shore and slowly sent it in.

"Survivability +1," Patian said.

Hongjun "。。。。。。 ”

After being speechless for a while, Hongjun stood up and walked in the direction of the World Tree, and it was time for the sunrise to come, and asked Patian as he walked, "Did you see the energy just now?" ”

"What you see is what I see."

"Can you calculate the impact on these animals?"

"Wait thirty seconds."

Hongjun came to the sundial and saw three horizontal lines of different lengths under the twelve scales.

"After calculation, the energy just now can allow all animal species to evolve in 100,000 years to complete the normal process of about 900 million years. It is accelerated by about nine thousand times. If catalysis is performed again later, the energy input will need to be multiplied, because the current species and total number are small, and the increase will be exponential in 100,000 years. ”

"So how much chaotic qi is needed for the energy just now?"

"If the energy just now is a unit, then there is a night before you absorbed the light of life and converted it into chaotic qi, the conversion ratio between these two substances is unknown, about one-third of the energy you converted that night gave the World Tree its current volume, and the rest is about sixty percent, and it has overflowed about ten percent over the years, and the remaining fifty percent You arranged to stay with the World Tree for half of it, then the energy just now is a quarter of the chaotic qi you stored overnight. This means that you can store about four units of Chaos Qi in a night. In this way, it takes about one and a half units before and after the world tree you created. Now, after the change of that core, you can now absorb it all over your body, and according to the current absorption rate, it can be calculated that it is more than twenty-four times that of before, and now it is dawn, and the moonlight time last night was ten hours and forty-seven minutes. Then you absorbed about a hundred units of energy last night. Combined with the present ... What the? Not right here! Patian suddenly shouted.

"What's wrong," Hongjun said strangely.

"The sundial projection is not the right length. Wait a minute, I need to look up the records for all previous years. Patian said urgently.

Didn't wait for Hongjun to say anything. Patian's voice came again. "The number of days on this planet has changed! In the first 1,000 years of the world calendar, there were 424 days per year, and according to the scale just now, after nearly 2 billion years, the current world calendar has only 389 days per year. When Hongjun heard this, he took out the leaves and said to the World Tree, "World Tree, has the number of days on this planet changed every year?" ”

"Yes hosts, there are changes, it seems that the number of days per year is slowly decreasing. But the change was very slow, and it didn't seem to be urgent, so I didn't have time to mention it. The voice of the World Tree said respectfully.

"Patian, calculate." Hongjun said.

A few minutes later, Patian said, "The data in the database shows that one rotation of a planet is considered a day, and one revolution around a local star is considered a year. There is no error in the way the sundial is displayed and recorded. It is to record the change of year according to the height scale of the nearest and farthest light of the planet reaching the star at the time of revolution, and will drive the change of the seasons of the planet. However, there is an assumption in the world in the database, the world that made me, that when the planets revolve, they form an ellipse at the farthest and closest point of the star, but at the beginning of the formation of galaxies, all the planets are affected by the thrust of the star when they are formed, and the muzzle velocity is larger, and the orbit of the early years is the larger the ellipse. Just like throwing a pebble, it is the fastest when it leaves your hand, and with the resistance of the air and the influence of gravity, it will inevitably slow down until it falls to the ground. The planet moves in a vacuum, but there is not nothing in the vacuum, so the planet will still be subjected to resistance in the process of operation, although the resistance is very small, but in terms of an extremely long time span, the planet is still slowed down a little bit. If the speed slows down, then it must take with it its orbit, that is, the ellipse, smaller and smaller. When the ellipse becomes smaller, the distance of this revolution is shortened, which is why the number of days per year is now about 35 days less than it was two billion years ago. ”

Hongjun listened to it and was suddenly lost. I think that the truth of how this world works really has its own set of theories. The scope of human change is really very small. At this point, Patian's laughter came over and said, "It's really interesting, according to this theory, the closer the planet gets to the star, the more sunlight it will inevitably absorb." The orbit is about close to the star, and the temperature on the surface of the planet must be getting higher and higher, and it is ridiculous that a group of scientists in that world should call it global warming, and entangle the cause to the industrialization of human beings. ”

Hongjun also felt that human beings were indeed a little arrogant, but he didn't know that human beings had little impact on the operation of the whole world. Over a long enough time span, no species can truly and profoundly impact a planet.

Speaking of humans, they now have the World Tree and Patian around them, but they each have their own limitations. The World Tree can monitor Blue Stars and craft objects, but has little to no ability to move. Patian has a lot of computing power and storage power, and based on the information provided by the database, he can give himself actionable advice on some specific things. In this case, it seems that you can try to create a human being, and if you can, then it is also a good choice to have someone to accompany you to relieve your boredom or fight down.
