Why don't I have a system like other transmigrators? This is Marvel, it's hard to survive without a system! Oh well, without a system, I can only rely on myself. First, I'll make a Green Goblin serum to improve my physical fitness, then I'll make an Iron Man suit to play with. An Iron Man suit seems too low-level, I'll just make a Vibranium suit instead. This is a story of a protagonist who uses his super high IQ to traverse the Marvel world without relying on a system.
