The strongest warrior

After the infection of a certain virus, the

death rate was reaching 30%. In a matter

of those three months, excluding the mass

deaths of animals, the population of the

world dropped by nearly 2 billion!"

"The survivors neared 5 billion, whom all

have a natural resistance against the

disease."

"During these nightmarish three months,

the whole planet experienced excruciating

pain."

"During this process, the 5 billion survivors

realized that their bodies have

strengthened. Virtually everyone's power, speed, rate of cell division, and skin

toughness have at least doubled! Even an

average man could easily surpass the

previous world champion in running and

weightlifting."

"And then... disaster started!"

"The humans who have lived so

comfortably have strengthened so much.

The beasts who have survived the RR

disease have went through even harsher

conditions. In their transformations, their

strength has raised surprisingly far beyond

humans'. And some of these horrifying

beasts got even smarter!"
