The gray-yellow swarm that swooped down on the wall this time was much larger than what Fang Chen had encountered at that time.

Moreover, Yu Yao found that the residue of the lethal agent did not seem to have an effect on them.

Gray-yellow paved the sea, and with the undulation of the tide, it hit the wall one by one.

Standing on the wall, Fang Chen could even hear the creak of this thing scraping the wall skin layer by layer.

Thinking of the toucan catfish that had been gnawed and there were no bones left, his heart twitched while his teeth were sore.

Zhu Ting and Yuan Bo, who rushed to hear the news, also frowned when they looked at the gray-yellow dragonfly larvae.

This is one of the after-effects of lethal agents, and after killing mutated sea beasts in an area, an imbalance in the ecosystem will follow.

As soon as the natural enemies disappear and the inhibition is gone, the creatures without restraint begin to reproduce and expand wildly.

In the past, the fish in the surrounding rivers were lit up, and everyone would only think that there were a lot of mosquitoes around that summer, and at most they were bitten two more bags when they slept at night, but now, it is not so simple.

Affected by the evolutionary hormones, the attack power has undergone earth-shaking changes, and as the population grows larger and stronger, the biological system has even been reversed.

And this transformation of the relationship will lead to this imbalance becoming more and more serious, without suppression, and even feeding on natural enemies, their population will become more and more inflated, and in serious cases, it will even lead to the direct collapse of the biosphere in the region.

And this imbalance needs to be adjusted, only and only in this area can there be creatures that re-evolve into its natural enemies, and this point in time is recorded in 10,000 years, think of kangaroos and rabbits in Australia, Yuan Bo feels that his head hurts and is about to explode.

The temporary solution can only be solved manually.

No one dared to go into the water, so they had to stand on the fence and use a large sieve of that quality.

Don't want to destroy, just don't gnaw at the wall again.

But when you really fish it out, you will know how good the teeth of this thing are.

Ordinary screens can be bitten through after only two fishing, and after changing them a few times, no material can last five times, and this includes barbed wire.

This thing is probably worse than concentrated sulfuric acid, and if the wall is bitten through and they really get in, it is estimated that they will melt clean up if they fall into it without even having a chance to pounce.

In the end, it was Zhu Ting who proposed to replace everyone's nets with black mud nets.

Once again, the strange mutant colony has exerted its power.

This thing really can't be bitten. When fishing, I only heard the black film creaking, but it never broke.

But this will not solve the problem at all, as the water fly fades into an adult, the fence can no longer stand, and the swarms of dragonflies hover overhead, and if you are not careful, you will be wrapped in dragonflies, and you can't wear anything, as long as you can't get out for a short time, it can gnaw everything on your body.

As the adults matured rapidly, they began to mate and reproduce, and the gray-yellow wave spread further, and within a few days, the walled dam was flattened by them.

Yuan Bochou's hair is going to turn white.

Flocks of red dragonflies flew around in the reserve, and no one dared to run out stupidly, they all wrapped themselves tightly and walked close to the water's edge.

If the dragonfly swarm surrounds you and you can't run anymore, you just pour it into the water, hold it in the water for a while, and wait for the dragonfly swarm to fly away and come up again.

But it's also something that can be used before the larvae bite through the fence and rush into the reserve, and once the wall is bitten through and the water bugs come in, then they really don't dare to go out.
