Doomsday: You Asked Me to Forge a Blade, So Why Am I Building Mechs?

A monster capable of overturning the world appeared, and all high-energy weapons became useless. Only cold weapons could slay the monsters.

In a world like this... perhaps only the strong could survive.

Yu Wenyuan had sluggish limbs and couldn't become a warrior who fought monsters.

But his mind worked faster than anyone else's.

In this age of mechanical technology, who said you had to be strong yourself?

Humanity became the master of all things because it knew how to use tools!

The mecha he created was stronger than any champion and more monstrous than any monster!
