Life originates in the ocean, and water is the mother of all things.

The two wide rivers of the Summoner's Canyon are the oceans of this world.

The first newborn life was born here.

However, things have gone awry.

In the small courtyard space, the partial pressure of oxygen is reduced, but it is not a real anaerobic environment.

Therefore, things are not as Zhang Zifan thought, and the first to appear will be the producers who use sunlight for photosynthesis.

Rather, it is a decomposer who decomposes the residual organic matter in the water.

To put it bluntly, it's a scavenging plankton.

Although the soil, sand, and water in the yard have all been sterilized and insects removed.

But many of the dead bugs, bacteria and corpses remain in the water and soil.

Some of these corpses were slowly petrified, carbonized, and turned into fossils.

Some are still circulating in the atmosphere, oceans, and soil in the form of organic matter.

The first type of plankton survives by breaking down organic residues in water for nutrition.

Although there was a deviation, Zhang Zifan was not in a hurry, but continued to wait.

Another six hours passed.

The time in the yard world has been spent for more than 100,000 years.

The nascent plankton gradually diverged.

Yes, they continue to search for residual organic matter in the water, playing the role of decomposers.

Yes, the structure becomes more complex and the number of cells increases.

They try to land and find new sources of food in this more nutritious place.

Others, abandon the inefficient decomposition mode.

Gradually, they evolved predatory organs and began to try to prey on their former counterparts.

For a time, the evolutionary tree began to have countless branches.

All kinds of bizarre creatures appear one after another in this small world.

The vast majority of them, in just a few minutes, were eliminated by nature because of the wrong evolutionary route.

Only a small part can survive the baptism of time and survive tenaciously.

Ten hours later, the world in the courtyard had passed a full 200,000 years.

Finally, the first producer who was able to use sunlight to synthesize organic matter and make oxygen appeared.

This is a blue algae with beautiful fluorescence.

Although they are preyed upon by other primitive predators, thanks to the sun's blessings, the cyanobacteria still survive tenaciously and begin to thrive.

Zhang Zifan looked at the blue light of the lower river and couldn't help sighing.

They were beautiful, but they came too late.

Looking at the sunset in the west, Zhang Zifan hesitated for a moment.

He fetched an oil lamp, restored the flow of time to one, and walked into the energy membrane.

Zhang Zifan felt that his breathing was still rapid.

This shows that the emergence of cyanobacteria is still too short, and the population is too small.

The oxygen levels of the whole world have not recovered.

Hang the oil lamp on the wall of the energy film, and Zhang Zifan lit it.

The fire was faint, which was caused by a lack of oxygen.

Zhang Zifan has seen such an experiment in a middle school textbook:

In 1771, the English chemist Priest placed the lit candle with the greenery in a closed glass cover, forming a brief circular equilibrium.

The oxygen production of cyanobacteria is much higher than that of green plants, so Zhang Zifan feels that the balance of his world may not be short-lived.

But for the sake of insurance, Zhang Zifan took out the ghost Taoist from the medicine jar and gently placed it on the edge of the lower river.

"The long night is coming, and I will go to the long sleep.

Before the dawn comes, you have two tasks.

First, to protect these blue floating algae from extinction;

Second, build a stone statue of me under the fire, and if the fire goes out, you pray to the stone statue, and I will wake up and come and deal with everything. ”

After saying this, Zhang Zifan turned around and prepared to leave.

Since he was not in the courtyard before, the time sense of the ghost Taoist was the same as that of Zhang Zifan.

He was in the bottle, through the thick glass, and watched Zhang Zifan tidy up the yard in a blur.

In the past seven days, the three views formed by the ghost Taoist in his life for more than 250 years have completely collapsed.

What is the change of dynasty, what is the supreme martial arts, what is the beauty of the incense car......

In the face of absolute power, they are too small to mention!

In these seven days, the giant slaughtered the billions of fierce beasts in the desolate world.

In the past seven days, the giant held a shocking giant axe that could not be seen in the whole picture, and cut off the two pillars of heaven.

In these seven days, the giant carried the sun and the moon in his hands, reshaped the mountains and rivers, and subverted the previous era.

Feeling the tremor of the earth, the ghost Taoist weakened his legs, knelt down in the direction where Zhang Zifan left, and shouted hoarsely:

"Please tell me, who are you! Did you create this fairy world, and what is the meaning of my ascension here!"

Zhang Zifan stopped, turned around and pondered for a moment.

He said lightly: "My name is Pangu, and you should be Hongjun!"

After that, Zhang Zifan did not hesitate, left in a hurry, and restored the time flow rate to 1 to 100 million.

In other words, in reality, one day in the courtyard space is nearly 300,000 years.

After doing all this, Zhang Zifan hurriedly rushed to the canteen to cook for himself and the lame old man.

The chickens have already eaten up, and if it's too late, you'll be hungry.

......

"I am Pangu, you are Hongjun?"

These two names are very unfamiliar, but the ghost Taoist understands what Zhang Zifan means.

"Okay, from now on, there will be no more ghost Daoists from the Tang Demon Gate in the world, only Hongjun Daoists who guard these blue fluorescent and heavenly holy fires!"

Standing on a high mountain cliff, looking at the blue fluorescence in the blue waves.

The ghost Dao man, or the Hongjun Dao man, had a solemn face.

He looked up at the sky, where the red sun seemed to be frozen, and there was no sign of setting at all.

"Endless night...... Will it really come?" Hongjun's eyes were full of worry.
