In the Marvel Universe, the Awakening System Helps Me Become Invincible

I am a Marvel movie and animation fan who traveled to the Marvel Universe after death and was given a system that can only be described as "super powerful" but with many limitations. At first, I was ecstatic about this system, but I soon realized that I was in an extremely dangerous world where my life was constantly under threat. The protagonist is not invincible at the beginning, it will take a period of time to grow! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
