The Ninja Academy's Incredible Legends (46) The Shinobi World is So Big, Yet I've Grown Weary of It

The damage caused by runaway biotechnology far exceeded that of natural disasters and invasive species.

Especially when artificially induced mutations could exert their influence through the food chain, the entire ecosystem would be forcibly dragged into an extremely unstable state.

Of course, as time passed, the law of the jungle—natural selection and survival of the fittest—would take effect. The many mutated species produced by this biological explosion would form a new balance and squeeze the newly emerged organisms out of their living space.

By then, the drastic changes in the ecosystem would gradually settle down. But how long that adjustment would take was anyone's guess. Mizuki was not a biologist, after all, and his research skills were only so-so. He had merely achieved his current results through knowledge far beyond the Shinobi World and the convenience of chakra.

A few * ago, it had not been so serious. It had been enough to have a few acquaintances clear them out whenever they had time, and it had not caused much of a stir. But now, things seemed to have gone beyond expectations.

Even if Mizuki acted personally, he could no longer guarantee that no fish would slip through the net. Things like mosquitoes, rats, and bedbugs were not difficult to wipe out for a time, but eradicating them completely was nearly impossible.

At this point, even Mizuki did not know how far their effects had spread. All he could do was suppress each outbreak as it appeared. Rather than seek total extermination, he could only hope to buy time and let nature's power and the passage of time restore the balance.

Fortunately, the Shinobi World had creatures known as ninja. They were only a few mutated organisms; they could not make much trouble.
