[Tragic life experience + system + multiple heroines + villains]
In his previous life, Lin Tian was picked up by Yun Xi in a ruins. Yun Xi saw that he had a good talent and stayed by his side to train him.
Later, because Yunxi had the body of Tianxiang, she was worried by the monks in the upper world. Lin Tian used his pure demon blood to fight against the monks in the upper world.
Lin Tian's own cultivation was still shallow, so he used his whole body's essence and blood to activate the Immortal-Devil-Slaying Sword, and died together with the people in the upper world.
The dead Lin Tian was selected by the system and reincarnated in the body of an elderly son of the Lin family.
Later, he broke through many obstacles and suppressed the gods in the upper world.
