Demon Cultivators of the Myriad Worlds

After joining the Demon Sect, Zhang Heng accidentally stumbled into the Myriad Worlds of the Manzong.

Bleach world: “Hollows? Soul Reapers? Aren’t they just ghost cultivators?”

One Piece world: “A Buster Call? What a waste. Let me use my Imperial Banner!”

In Naruto, even Orochimaru calls him a cruel Ninja God.

In Demon Slayer, he’s the foreign enemy who makes demons and the Demon Slayer Corps set aside their grudges and join forces.

Wherever the Demon Zhang goes, not a soul is left alive.
