Cultivating Immortality Through Dual Cultivation in the Apocalypse, I Forge an Invincible Sword Demon

As biochemically mutated monsters ravage the world, zombies seize the land's resources, forcing humanity to eke out a living underground.

Ying Ji obtains a passage to a cultivation world and steals the "Demon Sword" sealed away by the Sword Pavilion, a sect of sword cultivators.

The sword is drenched in bloodlust and must be fed human flesh and blood. Otherwise, it will corrode its wielder's mind, driving them to kill and devour until they become mindless walking corpses.

But if the Demon Sword is given enough people to devour, it can unleash boundless power and evolve without limits!

Ying Ji returns to the post-apocalyptic world, where countless zombies become nourishment for the Demon Sword.

From then on, he and the Demon Sword embark on a path of limitless evolution!

A hundred years later, in the cultivation world, the great masters of the immortal sects point at Ying Ji, stammering, "S-Sword Demon, don't come any closer!"
