I just wanted to make up for the regret of wasting my life in my previous life, but unexpectedly I discovered another side of the real world. It turns out that behind the scenes, there are still demons, warriors, and people with supernatural powers in the real world... So Xu Lang regained his strength while secretly eradicating demons and protecting his family and friends. But all demons can be eradicated, but those who are more demonic than demons cannot be eradicated. Hell is empty, the devil is in the world...
