The combination of the increase in natural enemies and the decrease in food will cause the population of mice to naturally decline.

When the number of mice becomes less and less, and there is not enough to eat, the living environment of natural enemy animals will naturally deteriorate, and the number will also decrease, and the resources that mice regard as food will gradually increase.

The population of mice will slowly start to climb again, reach a certain upper limit, then fall again, and then climb again...

This is the dynamic balance in nature.

The same was true for ancient apes in the past.

But after the emergence of the first ancient ape to create a grindstone weapon in the true sense, or the first to learn to preserve fire, or the first to think of sharpening a stick to obtain a weapon outside the body,

Humanity has embarked on the path of evolution of intelligent life, completely rewriting the dynamic balance originally dominated by nature.

Human beings have become the masters of the earth.

Now, rats have also embarked on this path of disrupting the natural ecology, and they have embarked on this path before another intelligent civilization, human beings, have not yet become extinct.

Zhou You has witnessed first-hand the higher survival rate of rat pups.

In addition, without going through any research, I can tell that the number of rats in the wild that have died from natural enemies and human behavior has dropped dramatically.

Even if rat eradication operations in various cities are in full swing, the number of rats living in cities is declining at an exponential rate, which is only a superficial phenomenon.

Because the situation of rats in the wild is completely different.

They have even been able to launch counterattacks against their natural enemies, eating cats, dogs, snakes, and even driving mustelid weasels into cities for refuge.

In addition, rats with improved intelligence will inevitably improve their ability to find and hoard food.

Therefore, Zhou You can conclude that in the next ten days or so, the number of rats will definitely increase significantly.

The basis for his judgment is very simple, because the gestation period of mice is three to four weeks, and the accurate number of 21 days can be used as the middle line.

Based on the current survival rate of rat pups, the global rat population will at least triple instantly, reaching 45 billion.

Then the female rat that has just given birth can start the next round of pregnancy after nursing and grooming for a month.

After another 21 days, another round of breeding begins.

Rats can reproduce 6 to 8 times a year, with a litter of 5 to 10 animals.

At this time, the young mice bred from the previous batch are almost two months old, about to become adults, and can also breed.

Therefore, it can be directly concluded that if no miracle occurs, in a year's time, humans and the ecological environment of the entire earth will face a terrifying rat swarm reaching trillions, or even tens of trillions.

Of course, the earth's ecosystem is likely to suffer a devastating blow by then.

But judging from the current trend, what if mice run into the farming era and take over various high-yielding plants developed by humans today?

What will happen?

This is not alarmist, but all signs are pointing in that direction.

Moreover, the premonition of doom that circulated around him also made him subconsciously imagine what it would be like to be a rat after entering the industrial age.

After thinking about these real horrors, Zhou You's mind returned to the status quo.

He began to estimate in his mind how many rats there were in Lelai County in ancient and modern times.

The total domestic rodent population is also 30%, which is very close to the proportion of the domestic population and the global population.

To some extent, the distribution of rats seems to have a positive correlation with human activities that is not accurate, but has certain reference value.

Therefore, Zhou You plans to use the population ratio to analyze the number of rats that may exist in Lelai County.

The total population of Lelai County is approximately 500,000.

Then, Zhou You can make a preliminary estimate that the total number of rats in Lelai County is about 1 million.

This number may have a large error, but it can have a certain reference value.

"So, how many rats are there in the cotton mill at this time? One hundred thousand? Two hundred thousand? Or even more?"

Zhou You murmured to himself.

However, Gao Zhanying's shout interrupted his thoughts.

"Mr. Zhou, we have arrived near the substation!"

Zhou You nodded, but did not immediately give the order. Instead, he turned to look at Gao Jianguo beside him, "Have you contacted your family?"

Gao Jianguo nodded, "Yes, we have been contacted. Principal Zhou said that only the basic garrison personnel will be left, and all other combat forces have been deployed. Principal Zhou said that they will arrive in fifteen minutes at the latest."

"good."

Zhou You nodded and looked towards the back of the airship cabin.

There were ninety mini kerosene-gasoline mixture incendiary bombs made from calcium gluconate oral liquid bottles, blue bottles.

The content of each bottle is only 10 ml. Counting the bottle, the total mass is about 20g.

I just brought this with me when I recently returned for supplies in the afternoon.

The research and development and reliability demonstration of this thing were completed at noon by the Zhou family arsenal, and it was just assembled in the afternoon.

One box, totaling ninety bottles.

Zhou You took this first box with him, not because he was Zhou You, but because this thing was a throwing weapon after all, but it was also very dangerous, so the best way to use it was to drop it from a high altitude.

But the Langya No. 1 single-person airship is too crude after all, and using open flames is too dangerous.

After thinking about it, we either have to use drones, or we can only use large airships like Langya 2.

Therefore, Zhou You took it with him, intending to find a suitable opportunity before using it. The main purpose was to conduct actual combat testing, just like Luo Xun was the first to use a home-made time-delay bomb in the morning.

After the verification is passed, mass production can begin.

Fortunately, this team did not encounter any serious battles before, and the cats, dogs, and rats they dealt with were not as crowded as the stray dogs that Luo Xun encountered, so until now, these ninety incendiary bombs have not been used.

once.

Zhou You had originally planned to set off a few randomly when he returned from a long day's work. It was not only a practical exercise, but also a fireworks to celebrate the success of all aspects of today's operations, but he did not expect that now it was time to rely on them.

It's time.

Since there are high-voltage wires near the substation and the line density is quite high, the airship does not dare to get too close at high altitudes. Instead, it first continuously lowers its altitude and barely maintains it at a height of 20 meters above the ground, and then approaches cautiously.

As the airship got closer to the ground, everyone looked down at the rats on the ground. It was no longer dark, and they could finally barely see the individual rats clearly.
