Marvel: I Become an Ancestor by Sacrificing Items

[Marvel + multiple heroines + abilities from countless characters across the multiverse + no knives + relaxed invincible]

He ends up in the Gwen Spider-Verse, transmigrated into Peter Parker.

Not only did he fail to become Spider-Man, he even got handed the role of a sacrificial cannon fodder... Peter is panicking hard inside.

Fortunately, he awakens a sacrifice system. As long as he sacrifices items related to Marvel characters, he can gain points to strengthen himself.

Radioactive spider remains, Mark I, Black Widow’s tight leather suit, the Heart-Shaped Herb, Chitauri ship wreckage, Asgardian warrior armor...

Sacrifice, sacrifice, I’m sacrificing all of it!

Rewards obtained: the Twelve Talismans, a Zanpakuto, the Navy Six Styles, the Rinnegan, a Kamen Rider belt...

At the start he lies low in the Big Apple City, and in the end he becomes a true tyrant.

Peter: I can do whatever the hell I want! Hey, purple potato over there, what are you looking at? Come out and fight me one-on-one!

Before Thanos can react, the heroines all turn around: One-on-one? With me?

Peter: ???

Something’s wrong. These heroines are too enthusiastic—what should I do?
