I Inherited a Haunted House with Demonic Employees?

[Urban High Martial Arts] + [Protagonist and Villain] + [Overhead Earth World View] + [Multiple Timelines] + [Multiple Heroines Redemption] + [Pretend to be a Pig and Eat a Tiger] This film is set in the current world of the 21st century. The protagonist Lin Li will experience three world views, namely the current 21st century, the devil's hell The world view (the protagonist pretends to be the Lord of Demons and eats the tiger), as well as the world view of the new order of the earth in the future. Lin Li is a quasi-college student. After learning that his grandfather was killed by the Awakened Organization (a demon hunting organization), he vowed to avenge his grandfather. In the process of exploring the truth, I discovered that my grandfather was actually an elder among the Awakened Ones, and he left himself a haunted house with all NPCs being demons. Is this trying to deceive others or... These demons who are NPCs are all powerful demon gods or vampire ladies. On the surface, they regard Lin Li as their boss and obey his orders, but will they really surrender like this? There has always been a "guest" living in Lin Li's body, and he can actually make him a king-like existence in the demon hell... When he returns to the human world, the world has been occupied by demons and humans have organized a resistance army. Which side will Lin Li stand on?
