The Ancestor of All Demons was a fantasy novel about immortal cultivation. It told the story of a tiger who was reborn as a demon and reversed the tragic situation of the demon race in the world. If you like novels of this style, I recommend the following: [Invincibility from Milk: A reborn baby becomes the new Holy King through the check-in system and becomes the leader of the Ancestor of Demons.] << The Sorcerer World >>: Become a child of a small family through a different world, and begin a powerful journey through a biochip with analytical abilities. < Creating a Mysterious World >: A man traveled through the 70s and 80s and accidentally obtained great power to create a mysterious world. I hope you like my recommendation.
