The cold wind howled, the heavy clouds obscured the sun, and the whole world was plunged into darkness.

Without sunlight, the planet's surface temperature plummets.

Low temperatures have destroyed the living environment of most organisms, and a large number of organisms have been exterminated in just a few minutes.

Li Qian did not go to prevent all this from happening, and civilization should maintain its freedom as much as possible.

As a former top scientist, even when it comes to his own life and death, he still maintains the rigor of his research.

However, there is still one plant that survives strongly.

It was a silvery-white plant about the size of an ant with four-petaled leaves.

Losing its rays of the sun, it seems to be conscious, and begins to evolve wildly, adapting to the dark environment.

Soon it spread out on the surface of the sea like lotus leaves, using almost all the places where it could absorb the moonlight.

Soon, it multiplied in large numbers and completely took over the entire planet.

Viewed from above, the surface of the planet seems to be wrapped in silver foil, glowing with a shimmer.

"It's kind of funny, I can adapt so quickly...... Let's call it the Silver Nightweed. ”

Li Qian summoned the system log and wanted to record all this, but a diary and a pen appeared in his hand.

He was stunned for a long time, shook his head and smiled bitterly, and put pen to paper.

This civilization simulator is always very rigorous in some strange place.

[In the Yuanwu Era, the cold air outside the sky came, and the world fell into a dark period of 10,000 years, ninety percent of the species perished, and only the silver night grass survived, becoming the overlord of this era. 】

Under the effect of acceleration, the 10,000-year dark period passed in just one day.

In the blink of an eye, the dark clouds broke away, and the sun shone on the earth again.

The scorching sunlight caused the silver night grass, which had been accustomed to the moonlight, to fall directly into a large withered state.

In just a few minutes, the Silver Leaf Grass was directly extinct, and none of them survived.

Compared to cold, which preserves life, heat is more lethal to living things.

Seeing this scene, Rao is Li Qian has studied biological science for many years, and he can't help but feel emotional.

"Everything is impermanent, life is fragile, and it is so difficult to evolve civilization."

The evolution of life is one birth and destruction after another.

From the perspective of the long time of the universe, the emergence of all life is as bright and short-lived as fireworks.

Li Qian let out a long sigh and recorded this extinction on the system log.

[Yuan Ci Wu Ji, the cold air dissipated, the scorching sun was in the sky, and the silver night grass failed to withstand this test and was completely extinct, so far, no creature has survived. 】

Putting down the log and looking up, there are no more multicellular organisms on the entire planet.

Once again, the world is in chaos, and only the most resilient single-celled organisms remain.

"That's not good, even an ecosystem can't be completely built, and civilization can be born in the Year of the Monkey?"

Li Qian is well aware of the difficulties of biological evolution, and at this rate, he will burp himself before he can evolve civilization.

"It seems that external intervention is needed to quickly advance the process of civilization."

The research institute has long been abandoned, and there are no materials to use.

Li Qian thought for a moment and decided to take the potted plants back to the repair shop.

Now that a way out has been found, there is no need to close the shop, and there are often all kinds of androids and cyborgs in the shop.

I can completely disassemble the parts from their limbs and put them into the virtual world to evolve.

……

Half a day later, he took advantage of the night to return to the repair shop again.

When he entered the door, when he saw the note, Li Qian smiled bitterly, folded it and put it in his pocket.

Outside the window, colorful neon lights are constantly reflected in the shop day and night, and the changes are endless.

He put the potted plants in the room where he rested on weekdays and began to think about how to intervene in the evolutionary process.

After two extinctions, the expansion of the universe has stabilized, and it should soon be able to develop smoothly.

But it will take a long time to evolve intelligent creatures.

I want to find a way to treat cancer, not really to engage in civilized research and deduction.

And the best way to speed up evolution is to add the mature genetic template of the current world to the virtual world.

Li Qian rubbed his jaw and pondered which creature would be best suited for addition.

"The strength of an ant can lift a hundred times its own weight, and a cockroach can cut off its head and still survive ......"

"From an adaptation point of view, insects should be the most suitable."

According to past scientific research, insects are capable enough to dominate the entire biosphere at the same size.

Tyrannosaurus rex and the like only became overlords by virtue of their size.

Having lost its massive physique, I'm afraid it's not as good as an ant.

After confirming that the planet's ecological environment has stabilized, he began to catch all kinds of insects everywhere in the shop.

Half an hour later, he was sitting in the bunk, gray and sweaty.

"This bug is too hard to catch......

Around him, there are dozens of glass bottles, and various insects gather among them.

For a while, the whole shop was like an insect market, and all kinds of insect chirpings were endless.

After careful selection, he finally chose the genetic templates of three creatures: ants, praying mantises, and spiders to add.

Under the intervention effect of external forces, the process of biological evolution seems to press the acceleration button, directly skipping the link of single-celled organisms.

A large number of multicellular organisms evolved wildly and began to climb onto land, and groups of terrestrial organisms appeared.

In the same way, all kinds of plants began to grow, spreading wildly across the planet.

So far, it has only been half a day since he added the gene template.

"The terrifying speed of evolution, only 5,000 years, is comparable to the evolution of the past 20,000 years, but this is only produced under the effect of external forces."

The development of science and technology requires accumulation, and he does not intend to rely on the power of science, but to think of ways from the species itself.

Before he froze himself, the Human Genome Project was in the middle stages of development, and he barely got a glimpse of some of the secrets of the genes.

There are a total of five sets of genomes in humans, and by adding external genes, the ability to mutate can be obtained.

He only needs to breed creatures with extraordinary genes and transplant their genomes into his body to cure cancer through mutations.

But what kind of genome can cure cancer?

He pondered, his gaze inadvertently falling on the high-precision mechanical prosthetic leg on the cabinet, and a flash of inspiration flashed in his mind.

"As a cympanic, as a cympanic, as long as the parts are not damaged, they can live forever, and if the genetic template of the simulant is added, maybe it will have an effect!"

The plan was determined, and Li Qian began to implement it.

From the simulated muscles on the high-precision mechanical prosthesis, the living biological cells are extracted and placed on the planet.

He didn't have that much time for batch control experiments, so he had to use the simplest method.

Natural selection, survival of the fittest!

Whoever can resist the mutation is the overlord of this era!
