From the Start as István III, I Returned with the Dead

(Warhammer 40K, characters from Warhammer 30K to 40K, transmigration, reviving the Imperium, a sarcastic protagonist and a bratty System, ten jokes per chapter)

Zhou Tianyi, an ordinary college student from 2026, is summoned by a mysterious force to the Warhammer universe. From the start, he lands on Isstvan III, surrounded by Chaos cultists. In this moment of peril, he uses the System's abilities to summon the loyalists from the rebel legions who fell on Isstvan III.

Fulgrim: Saul Tarvitz, my proud son, you're back. Is this for real?

Angron: Kill! Kill! Kill! (What's a War Hound? Doesn't matter.)

Mortarion: (The second most awkward one. Doesn't want to go see Garro.)

The Super System can do more than just resurrect the dead. It has plenty of other abilities that will unlock later.
