Essence Devouring Art

In his original world, Wu Dao was the strongest cultivator that broke human body's limits by his Essence Devouring Art. After clashing with a creature-destroying missile, he transmigrated to another world, becoming a slave in a mine.

“Last question. If someone is killed in the mines, does the Four Seas Gang do anything about it?”

“No… they don't care. They don't see us as human. If someone dies, they're just replaced.”
