Doomsday Rebirth: I Slaughter the Zombie Horde with My Bare Hands

[Zombies + keeping a low profile + supernatural abilities + power levels + no System + reborn + no saintly do-gooder]

In July 2035, at Base Zero in Longcheng, Shenzhou, the final battle between humanity and the corpse clans comes to an end.

Four missile silos thunder open. Orange-red flames tear across the sky as nuclear warheads with a yield of fifty million tons of TNT sweep over the wasteland.

After the white light fades:

Below the seventh tier: vaporized.

Seventh tier: gravely wounded.

Eighth tier: lightly wounded.

Ninth tier: unscathed.

Carrying the seed of humanity's genes, the near-Earth orbital station heads for the depths of space. The explorers at the Mars base become civilization's last hope for survival.

In the military camp, Xing Guang watches the invincible alien race on the screen, unwillingness filling his eyes.

When his consciousness awakens again, he has returned to December 2020, five days before the apocalypse begins.
