I'm in the Armor World, and I'm An Muxiu

After staying up all night watching Armor Hero, I unexpectedly died suddenly and transmigrated into another person's body.

The good news: the original owner has an extraordinary background and is a famous second-generation heir. It probably won't be possible to live a hard life in this lifetime.

The bad news: he's a demonic second-generation heir, the kind who won't live very long...
