Marvel: Saving Iron Man from the Start

Genius scientist Qin Yu is accidentally transmigrated to the Marvel Universe after a laboratory accident.

Although he arrives in person and has no superpowers for now, Qin Yu obtains a "Superhero Sign-In System." As long as he is within one meter of a superhero designated by the System, he can sign in.

The first designated superhero: Iron Man.

"Ding! The target superhero's health is below 10%. Sign-in conditions not met. Host, do everything you can to raise the target's health."

So Qin Yu saves Tony Stark, who is covered in shrapnel, and puts an electromagnet in his chest while he's at it.
