The Fiercest Man on the Continent

He transmigrated, then transmigrated back. So he really does have a System?

And that irresponsible master of his is the toughest person on the entire continent?

Unfortunately, his master never bothers to teach his disciples, so he has no choice but to cultivate on his own. Luckily, he has a System: he can exchange for superweapons by crafting weapons and completing missions.
