[Wish fulfillment + invincible protagonist + no heroine + ruthless and decisive]
Niu Shisan transmigrated into an apocalyptic world teeming with ghosts and monsters.
The ghosts and monsters in this world are powerful and numerous, and most humans have become their prey.
He awakens a mysterious ability tree. What should he do when one Thunderbolt Talisman isn't enough to deal with a powerful ghost?
Print hundreds of them and wrap the thing up like a mummy in talismans.
Chanting spells hurts your throat?
Just record them with a megaphone.
You still use axes to kill ghosts? I'll just blast them with a shotgun.
People cultivate and spend every day practicing useless skills granted by the gods. I'll cultivate immortality and become a god myself.
Just as humanity is about to give up and accept its fate of extinction, Niu Shisan uses the System to activate electromagnetic pulse bombs and wipe out the ghost army.
He unlocks the ability to cultivate immortality and repels the Twelve Ghost Emperors with a casual wave of his hand.
Then he leads an army of nanomechs into the void to find and kill the Immortal Sovereign.
