Water

Chemical usage

Hydrogen bond,
It makes all life on earth possible.
It creates the source of water giving all life the blood in the arteries.

When you want to attack life forms on earth,
in the future there is a method of deleting the hydrogen bonds by which it
shatters.

It works like a virus, example,
a virus aters dna to create new viruses.
A virus can enter each life form with dna and has its
treacherous effect on it.

In the case of dna and virus. When a substance is found to
defend against the virus, a new dna structure must be developed.

The case of the substance demolishing the hydrogen bond,
it lets the creature dissolute.
