There Are Ghosts in Another World: Don't Panic, Senior Brother Shi Jian Is Here

[Reborn in another world] + [Thunder-and-Lightning Master Shi Jian] + [System] + [Monster Grinding]

Bad news: I croaked.

Good news: I transmigrated.

Bad news: This world is overrun by demons, monsters, ghosts, and spirits, and human lives are worthless.

Good news: The essential transmigrator cheat has arrived: the System.

Shi Jian: You called me here to help shoulder this burden, didn’t you?

Demons, monsters, ghosts, and spirits: A puny human who doesn’t know his place!

Shi Jian: Take this! Lightning Thunder Fist! Aah!

Ghost: Don’t come any closer!

Shi Jian: People say I’m a bad guy. I won’t deny it, but nobody’s ever called me useless.
