Chapter 1546, the confrontation between natural enemies and prey
The senior management of the gathering place felt relieved about this.
After all, no matter how powerful those beasts are, they can't compare to human wisdom.
In front of humans, no matter how powerful the beast is, it can only be reduced to a corpse.
But Fang Xiaoyue didn't think so. He felt that the Qingshui Lake gathering place was a bit dangerous.
Because when he was searching for medicinal herbs in the wild, he discovered a problem.
In the past, the intelligence of cannibal rats could only reach the level of a two or three year old human child.
But as the number of man-eating rats has been greatly reduced, their IQ has increased.
Of course, the biggest culprit here should be Fang Xiaoyue herself.
Because those man-eating rats with increased IQs should be the descendants of rats that consumed bloodline pills.
He captured a man-eating rat with the highest IQ, whose IQ reached the level of an 8-year-old human child.
Of course, this does not rule out the possibility of man-eating rats with higher IQs.
Because the number of indigenous man-eating rats in the wild has been greatly reduced, their territory is actually being rapidly encroached upon by new types of man-eating rats.
At the same time, the new man-eating rats mix with the indigenous man-eating rats, and the blood genes are inherited in the same way. However, cannibal rats with insufficient brains will be killed by humans, while cannibal rats with higher IQs can avoid human settings.
traps and pass on their genes.
In other words, if the reward order announced by the top management of the Qingshui Lake gathering place has always existed, then the hunting teams that are constantly attacking are actually helping to select the genes of cannibal rats from generation to generation.
As a result, the IQ of the man-eating rats will become higher and higher, and it is impossible for the hunting team to kill all the man-eating rats and completely eliminate this hidden danger.
It's not that Fang Xiaoyue has never thought of a solution to this problem.
He also refined blood-weakening elixirs and fed the blood-weakening elixirs to many cannibal rats, letting these cannibal rats mix into wild cannibal rat groups in an attempt to make the cannibal rats breed offspring with lowered IQs.
.
But this method soon proved to be completely useless.
The reason is very simple. The structure of the cannibal rat group is similar to that of the wolf pack. Only the strongest cannibal rat can defend the king of the cannibal rat group.
Only the Rat King has the power to reproduce!
After the man-eating rats fed by Fang Xiaoyue entered the rat group and participated in the battle for the rat king, they were no match for the blood-enhanced man-eating rats and could only be reduced to the bottom of the rat group.
As a result, a weakened man-eating rat with a weak bloodline that does not even have the power to reproduce has no possibility of leaving any offspring, and it is impossible to fundamentally reverse the trend of cannibal rats becoming more and more intelligent.
Of course, in view of what he had done and to finish it off by himself, Fang Xiaoyue also quietly beheaded those rat kings in the wild.
For Fang Xiaoyue, as long as the rat king is discovered, no matter how powerful the man-eating rat rat king is, he will not be able to escape his pursuit.
But as I said before, man-eating rats are getting smarter and smarter.
After Fang Xiaoyue secretly killed more than ten rat kings of the rat group, all the remaining rat kings of the rat group hid underground.
They no longer appear on the ground, nor do they affect their command and influence over the rat swarm.
Anyway, the rats will continue to send food underground for the rat king to eat. The main role of the rat king in the rat colony is to continuously reproduce offspring, so whether it is on the ground or not, it will not have much impression on the rats.
As a result, it becomes much more difficult for Fang Xiaoyue to catch the rat king of a rat group and kill it.
And the most terrible thing is that even if he kills a rat king, after the rat group is leaderless, it will take at most one day to choose a rat king from the many strong male rats.
Therefore, if Fang Xiaoyue wants to continue her bloodline weakening plan, she can only eliminate all the male rats in a rat group.
But in this case, it would be easier for Fang Xiaoyue to kill all the rats.
But it is very difficult to completely kill a rat group at present.
Fang Xiaoyue once tried to plug all the mouse holes and then poured in volatile poisonous elixir water.
This method kills 98% of a rat colony, but there will always be a few cannibal rats that successfully survive the poisonous attack and become more poison-resistant cannibal rats.
Fang Xiaoyue spent two months and used various methods, and was shocked to find that the remaining cannibal rats became stronger one by one.
Not only have their resistance to toxins been greatly improved, but they have also learned to swim, holding their breath while burrowing quickly in the water. They can even survive strong acid.
Even in flames, they can survive for several minutes.
In short, the more Fang Xiaoyue tortures them, the surviving man-eating rats will continue to evolve and become stronger and stronger.
Of course, if he could kill all the targeted man-eating rats every time without leaving any behind, he would be able to solve this problem.
But the problem is that this plane has great limitations on extraordinary abilities. Even his heating ability is now close to its limit.
And without powerful extraordinary abilities, it would be impossible to kill all the cannibal rats with his current physical fitness.
But then again, he has another way to deal with man-eating rats.
That is to cultivate a large number of natural enemies of man-eating rats such as ferrets, cats, eagles, etc., and with quantity versus quantity, they can always suppress the cannibal rats, and then eradicate them bit by bit.
Of course, this would require a lot of bloodline pills and time.
In fact, after failing to eradicate the man-eating rats, the main elixir Fang Xiaoyue refined during this period was the bloodline elixir.
However, before Fang Xiaoyue's plan could be fully launched, greater trouble came.
At this time, the Qingshui Lake gathering place received calls for help from three nearby gathering places.
It should be said that in the post-war ruins era, the relationship between gathering places was not so good. Everyone wanted to annex other gathering places and strengthen themselves.
After all, the beauty of power is to control more human and material resources for one's own will.
Human beings will naturally seek more power to satisfy their own desires.
Therefore, any gathering place is wary of other gathering places.
If it were not a last resort, it would be impossible for these three gathering places to ask for help from other gathering places, because this would be equivalent to putting themselves on someone else's cutting board.
The reason why these three gathering places asked for help is simple: they were besieged by a wave of cannibal rats!
Fang Xiaoyue also heard the news, and while being shocked, she also understood.
It's actually not surprising that something like this happens.
Because the cannibal rat population will inevitably spread outside without sufficient food sources.
In this case, it is normal for the three gathering places to be besieged by man-eating rats.
One of the reasons why such a situation did not occur in the Qingshui Lake gathering place is that the Qingshui Lake gathering place has been continuously cleaning up the man-eating rats very early, so that the number of man-eating rats in the surrounding area is not large.
The second is that Fang Xiaoyue will go out and mess with the man-eating rats when she has nothing to do.
In this way, when facing a danger that they cannot cope with, the man-eating rats will stay away from the Qingshui Lake gathering place based on their instinct to seek good luck and avoid evil.
The Qingshui Lake gathering place is fine, but the rest of the gathering places are miserable.
By the time the top management of the Qingshui Lake gathering place held a meeting and decided to send troops to help, one gathering point had already been destroyed by man-eating rats.
The troops sent from Qingshui Lake Gathering Area were attacked by a group of man-eating rats before arriving at one of the gathering areas.
In the end, only less than 500 of the 2,000-strong army escaped, and the remaining soldiers and heavy equipment were all killed by the rats.
Fang Xiaoyue had already left the Qingshui Lake gathering place at this time.
No way, there is not much use for him to stay at the Qingshui Lake gathering place now. It is better to carry out his own plan in advance.
So he returned to the volcanic zone.
After all, as far as he knew, the volcanic zone was probably the place with the highest density of organisms, which was more suitable for a breeding plan.
After taking Wang Xiaoya back to the volcano, Wang Xiaoya was happy and rode Yunli around everywhere every day.
While Fang Xiaoyue continued to collect herbs and ores, she also began to collect the young and eggs of various wild beasts and raptors on the volcano.
Of course, the focus is on the mustelids and ground finches.
Compared with other wild beasts and raptors, mustelids and burrowers are very weak, but they are the strongest hunters for killing rats.
Weasels include weasels, stoats, black weasels, etc. They are characterized by their slender bodies, flexible movements, and extremely high hunting skills.
Everyone thinks that those with the highest hunting skills should be large beasts such as lions and tigers.
In fact, the hunting success rate of lions is only 17%, while the hunting success rate of tigers is higher, more than 27%.
But the hunting success rate of mustelids is as high as 85%!
The reason is that mustelids mostly feed on rats and small birds. Their slender bodies and flexible movements allow them to easily get into rat holes and hunt down rats.
As for the ground finches, which were a member of the Corvidae family before the war, they were larger than magpies. However, after genetic recombination, they became smaller but also became more ferocious and intelligent.
They often settle in rat holes and use their sharp beaks and claws to hunt rats for food.
Fang Xiaoyue refined two kinds of elixirs.
The first is the Duo Zi Dan, and the second is the simple version of the Bloodline Dan.
The effect of Duozidan is that users who take it can give birth to more offspring.
Ordinary mustelids have a litter of about 3-5 cubs. After taking this pill, more than ten cubs can be born in a litter without damaging the vitality.
As for the simple version of the bloodline pill, its main purpose is to allow the cubs to grow into adults quickly in a short period of time and improve their strength a little after taking it.
Weasels and burrowers are originally one of the natural enemies of man-eating rats. As long as their numbers increase, whether their strength improves or not is a trivial matter.
After Fang Xiaoyue collected a large number of mustelids and ground finches, Wang Xiaoya had no time to go out and play. The first thing she did when she got up every day was to feed the tourist animals and ground finches.
This is a physical job.
More than three hundred kilograms of beef need to be cut into small pieces and fed to mustelids and ground finches.
And after these tourist animals and ground-burrowing sparrows gave birth to babies and laid eggs, they needed more food, and even Yunqiu, who had been doing nothing in the past, was driven out to hunt for prey.
But the hard work is worth it.
Within half a month, Fang Xiaoyue had cultivated more than a thousand mustelids and ground finches with improved bloodlines.
After that, he spent a few days using Xiao Yinzi and Yunli to send these little guys to the gathering place of Qingshui Lake.
In fact, the Qingshui Lake gathering place at this time was already in danger.
Because just over a week after Fang Xiaoyue left, the man-eating rat swarm spread again.
Every day, a large number of man-eating rats swarmed under the city wall, staring greedily at the guard soldiers swimming on the city wall with their green eyes.
Soon, these extremely hungry man-eating rats launched an attack on the Qingshui Lake gathering place.
Initially, these man-eating rats directly attacked the gate of the gathering place.
Although after the Qingshui Lake gathering place discovered that man-eating rats appeared around, they built a high anti-rat wall behind the gate to block the cannibal rats that might sneak in.
But those man-eating rats quickly rushed in through the sewers of the gathering place.
After paying a heavy price, Qingshui Lake District closed the sewer.
Although this resulted in the wastewater in the gathering area being unable to be treated, so that the sewers poured back into the gathering area from time to time, creating a stench.
But this at least guarantees the safety of the gathering place for a certain period of time.
But the learning ability of those man-eating rats was so strong that they quickly learned how to climb straight walls.
After all, although the city wall is very straight, because it is a brick-concrete structure, there are gaps between the bricks for climbing.
Fang Xiaoyue saw with her own eyes that the Qingshui Lake gathering place fell into chaos.
A large number of cannibal rats swarmed into the gathering place, and a fierce battle broke out between humans and cannibal rats.
Both the guardsmen and the elderly and children used whatever they could find around them to beat the man-eating rats desperately.
Of course, with the number of man-eating rats, the Qingshui Lake gathering place will inevitably collapse, and even the number of humans who can survive will be pitiful.
But Fang Xiaoyue still released the mustelids and ground finches he had cultivated.
The intelligence of these mustelids and ground finches is not very high, but their instinct as beasts makes them gather together in groups at the first time.
Some mustelids and burrowers left the group and attacked the man-eating rats.
Due to their local numerical superiority, these mustelids and ground-boring finches easily hunted down a large number of man-eating rats, even killing the rat kings of several rat groups.
Then these mustelids and burrowing finches began to breed on the spot.
With the help of Fang Xiaoyue's continuous feeding of bloodline pills, the reproduction speed of these animals has been greatly increased.
Originally, the gestation period of these mustelids and ground finches was 30-35 days, but here, it only took them a week to lay their first batch of young and eggs.
The nearby man-eating rats provided their cubs with abundant food, and the elixir prepared by Fang Xiaoyue with the Bloodline Pill significantly shortened the growth rate of the cubs.
In just one month, the number of mustelids and burrowers surged to 30,000.
In the following breeding period, they need to kill 500,000 man-eating rats every day to keep their young fed and drunk.
