[In the third month, you escaped from the closed laboratory, you gained freedom, stimulated by the natural environment, you matured, driven by instinct, looking for something]

It has been nearly a month since I came to the underground drainage system.

During this time, Zhao Meng gradually adapted to life here.

Even if he is a guinea pig used for experiments, compared to ordinary gray mice, he does not have the ability to survive in the wild.

But with the support of a lot of simulation experience, he still managed to survive with great difficulty.

"The underground drainage system is indeed a natural burrow for rats."

The tentacles on Zhao Meng's sharp nose moved slightly, and he could feel a lot of unique smells.

In the unpleasant smell of sewage, he sniffed out a smell that he instinctively yearned for, the scent of a female.

"There's a breeding target!"

Zhao Meng followed the taste and searched for it.

Although he was only three months old at this time, he was an adult as a rat and was able to carry out normal behavior.

It is even said that as experimental mice, they mature earlier.

But for the sake of the success rate, Zhao Meng still waited until his body was completely strong before he came out to look for something.

It is precisely because of the short reproductive cycle and fast reproduction rate of mice that mice have become important biological experimental materials for humans.

"Squeak!"

"Squeak!"

Zhao Meng heard the cries of other mice, and after turning a corner, Zhao Meng saw several rats gathered together, as if they were lying down.

It's just that there seems to be some disharmony in this party, and they are fighting with each other.

"Sure enough, it's going to start again!"

"It's a familiar track again!"

Zhao Meng, who watched this scene, already understood it, Zhao Meng, who had simulated a large number of animals, knew very well what would happen next, and he couldn't understand the experiment.

But he's pretty good at it.

"I'll do it too!"

……

In a burst of squeaking, Zhao Meng gained the initiative to lie down.

"Speaking of which, the forelimbs of rats are so similar to human hands."

On the "initiative", Zhao Meng looked at the thin five fingers on his forelimbs,

This is the finger on the mouse's paw, and it has the same grip as a human finger, except that instead of the smooth human shoulder, he is now grasping the mouse's fur.

"It's a mammal, it's very similar in every sense of the word!"

As the leader of the party, Zhao Meng ended the party, and the rats soon went to their own business.

Only Zhao Meng was still resting in a corner:

"Either way, the mid-term mission of the simulation is complete!"

"Even if this simulation fails, you can still see the available entries."

"It's a bit strange to say just now, it seems to be too fast!"

Zhao Meng thought back to the process just now, Zhao Meng's heart moved slightly, he always felt that the rat's behavior was too fast.

Although under natural conditions, it is not possible to overtime, but it should not be so short, can the reproduction process really be completed in this state?

Zhao Meng didn't know about this, he was just trying to survive, and he was still insisting on it in order to simulate success.

After all, it was not an easy thing to escape from the previous experimental base, and in the process, it was full of coincidences.

Zhao Meng tried again, I am afraid that he would fail again.

Luckily, the rats didn't live long, and he didn't need to last long in this simulation.

……

[In the fourth month, the accumulated strength drives you to do something. 】

"Is it going to start again?"

As one of the most fertile mammals on the planet, Zhao Meng knows that this animal has a fast cycle.

But entering the next cycle so quickly, Zhao Meng is still a little uncomfortable.

After all, most of the animals he simulated before had seasonality in reproduction.

As a mouse, it can give birth to offspring anytime and anywhere, and it is no wonder that there is a separation of male and female in the laboratory, and if they are put together, it may cause chaos.

It was that familiar place again, and it was that familiar corner, in the party, after a squeak, Zhao Meng once again grasped the initiative of this gathering.

The forelimbs that he usually uses to run, again grabbed some kind of fur,

In this state, Zhao Meng somehow thought of an outrageous hypothesis in his previous life.

Mammals go from crawling, to supporting forward, to being able to stand upright, and it is likely that they have been using a certain posture for a long time.

Thinking of this outrageous hypothesis, Zhao Meng smiled helplessly in his heart,

How can human walking upright have anything to do with this, humans walk upright to adapt to the savanna environment, not to change posture.

"Huh!"

In Zhao Meng's cranky thoughts, the party ended again,

"So fast!" Zhao Meng, who had the last experience, finally discovered the clues.

"I see."

"What was expelled was a gel that resembled a grain of rice."

Unlike the previously simulated cattle, cattle, a large mammal, are heavily liquefied and discharged.

But as a mouse, it's more like pulling out a transparent grain of rice.

He expelled a structure that was close to a monolith, and he never imagined that the structure of a mouse would be so different from that of a human.

"I didn't expect such a common animal in daily life to have such unique characteristics."

Feeling the difference, Zhao Meng sighed in his heart,

Although the rat is unique, no one picks up the rat that is gathering and deliberately observes the phenomenon.

What a wicked person would pay attention to this kind of thing and search for videos on it.

Zhao Meng is not this kind of person, because he is experiencing this kind of thing firsthand.

He even wondered if the unique excretion method of mice would continue to evolve and form a cluster structure similar to that of egg cells.

Zhao Meng didn't know,

But he knew that this unique state of convergence was also one of the tricks for rats to reproduce quickly and end the battle quickly.

……

[In January of the following year, you sniff out a unique smell and instinct drives you to do something. 】

"Here we go again!"

More than a year has passed since he came to the sewer, and Zhao Meng can feel his body aging day by day.

"Sure enough, the research from the previous life was right."

In his previous life, Zhao Meng read an experimental report that after neutering male rats, the lifespan of mice would be doubled.

Not only male rats, but also other mammals have a similar effect.

Unfortunately, this kind of experiment is like a phenomenon that occurs in mammals as if females fuse and retain genes.

In humans, it is an unprovable, unspeakable hypothesis.

Although Zhao Meng obviously felt that his rat life was shortened because of frequent work, Zhao Meng did not try to prolong his life.

He even said that he just wanted the simulation to end quickly, after all, the environment in the sewers was really not friendly.

……

Sniffing the smell, Zhao Meng came to the familiar place again.

After a scuffle, Zhao Meng's hand smoothly grabbed his shoulder, not a rat's fur, and began a rapid and extremely lossy behavior.

It is not without cost for mice to form this grain-like crystal structure.

Although the speed is increased and the odds are improved, it also causes the rats to pay more nutrients.

Therefore, neutering is extremely significant in prolonging the life span of mice.

……

"Rat and mouse, I'm going to be unable to beat these young juniors next time."

Zhao Meng looked at the losers around him who were driven away by him, he let out a long sigh, Zhao Meng could feel that he had gradually slipped from the peak this year.

The replacement of rats is extremely fast,

Female mice can give birth to a litter of mice in three months, and a litter of mice can have as many as a dozen.

The baby mice can mature in three months, and if the resources are sufficient, the mice can achieve exponential growth.

If you are in a granary that is not well guarded, there is a possibility of a rat tide of no small scale.

Under this iteration of rapid updates.

It is difficult for him to establish a complete community system on his own, and Zhao Meng cannot maintain a certain status like monkeys or other mammals.

Every time he faces a new rat, he faces a new fight, but thankfully, every time he encounters a new rat, it's a young one.

[In the third year, February, instinct drives you to do something, but the aging body makes you feel powerless]

"Disgusted!"

Although Zhao Meng used human wisdom to win the party by using some tricks,

It's a pity that those female rats didn't accept him, maybe because of the smell of old people in his body,

Or maybe it's hard for him to condense crystals like grains of rice, in short, he's disgusted and rejected.

"Animals behave much more simply than humans!"

Feeling the aging of his body, Zhao Meng didn't ask for anything anymore, and found a quiet place to prepare to spend his last life.

If you were a human,

Even though he is old, but money can make the ghost grind, and he has enough ability to make other existences not dislike him, and not dislike the old man smell in him.

But unfortunately, as an animal, it is only guided by the breeding of offspring, and there are not so many complicated relationships.

[In May of the third year, your organs begin to fail, and your life is coming to an end]

In a crack, Zhao Meng ate the stored food,

Feeling the demise of his life,

Although he has experienced this process countless times, he still has an indescribable feeling in his heart every time he experiences it.

For the helplessness of dying, for the helplessness of gradually unable to act, his consciousness seems to be slowly closed by a gradually shrinking box, until it is finally crushed and died.

This horror of the loss of life may be one of the sources of most people's desire for immortality.

"I'm going to die!"

Zhao Meng's consciousness gradually blurred, and at this time, a drop of water fell from the top of the wall, making the consciousness that was about to disappear sober up again.

Because he has not been active in the sewers for a long time, Zhao Meng's fur at this time has regained its previous color.

It's just that the fur is not so white, but has a little gray.

"I don't know what kind of entries I got from this simulation."

"Can you solve the lockdown status outside?" “

Thinking of the state outside, Zhao Meng didn't know what picture he remembered, and his little mouse heart began to beat rapidly.

But it was this kind of rapid beating that impacted his already weak body,

In that moment, like a broken string, his heart suddenly stopped beating,

In this wonderful picture, the little mouse suddenly smacked.

Little by little, his consciousness left his body, and at the same time, the prompts of the system appeared in front of him:

【Simulation Success】

Looking at the prompts of the system, Zhao Meng's consciousness relaxed, and his consciousness began to return to his body.

The first thing that was transmitted to his consciousness was the touch of the forelimbs.

"Wait!"

"It's ......"

At this time, the influence left on him by the rat had not been completely cleared, and Zhao Meng thought that he was catching the fur of the mouse.

But at this moment, the phantom of the head and snake tail in the illusory space flickered slightly.

The memories of the mouse were stored in his mind like a movie picture,

The influence of the rat on him disappeared, and the instinct about man returned.

At this time, Zhao Meng finally reacted, it was not his forelimbs but his hands,

And his hands are not clutching any fur, but smooth shoulders.

At this time, more feelings returned to his human consciousness, and worse feelings were perceived by his consciousness, and in that moment, Zhao Meng almost lost control.

But then, the flames that seemed to burn him to the dead scorched him, and even under the protection of feathers, Zhao Meng still felt a scorching heat.

However, it was precisely because of this fire that Zhao Meng woke up slightly, and his consciousness moved back to the previous virtual space.

"Almost out of control!"

Zhao Meng, who returned to the space, let out a sigh.

Although he had long known that his consciousness would face this situation when he returned to his body.

But what I can expect is completely different from my ability to take the initiative to control it.

It's like a human leg catching a cold at night, or swimming in cold water, and having cramps.

Although human beings want to control it, the instinctive reaction of the neuromuscular system is to make that leg twitch uncontrollably, causing unbearable pain to human beings.

Zhao Meng is not afraid of pain, but in that inexplicable situation, he always has a premonition that if he gets out of control, it will inevitably have a bad effect.

After all, the situation in the ball of light was too weird, and he still didn't understand why it had become like this all of a sudden.

"I hope that the entries obtained this time can find a solution to the lockdown."

"If we continue like this, sooner or later we will get out of control"

Thinking of this, Zhao Meng looked at the phantom of the head and snake tail, and a colorful lottery holder had already appeared in front of the phantom, waiting for him to draw the next entry.

Zhao Meng didn't hesitate, touched the lottery, and with a blue light, the content of the entry appeared in front of Zhao Meng:

【Small rodent (blue)】

"You'll get specialized teeth that are extremely aggressive to root-like objects and can bite through small crevices."

"Forehead ......"

Looking at this entry, Zhao Meng was silent.

"Do you want me to really bite off and unlock it?"

This entry seems to be helpful to the current situation, but Zhao Meng can't choose, not to mention whether his teeth can be broken, and his neck can't do it.
