Resurrection of Spiritual Energy: the Great Demon King of the Super Martial Age

Spiritual energy recovery + super martial arts + rebirth + talent + decisive killing + single female protagonist The spiritual energy revived and the era of super martial arts came, which changed the fate of a pair of poor children. The change of fate was both lucky and unfortunate for the two of them. In the 13th year of the Chaowu era, Xuanxuan died. From then on, Ling Yu embarked on the road of revenge for Xuan Xuan. By practicing taboo skills and doing whatever it takes to increase his strength, Ling Yu, who is harmless to humans and animals, eventually became a demon king in the eyes of the Earth Star people. In order to have enough strength to kill the mastermind behind Xuanxuan's death, Ling Yu did not hesitate to sacrifice hundreds of millions of people on Earth. After Ling Yu successfully avenged Xuan Xuan, his body and soul also collapsed due to practicing forbidden skills. Because of the monstrous killings during his lifetime, Ling Yu's soul returned to the Hell after death and suffered endless torture day and night. Suddenly one day, Ling Yu was reborn a few days before the advent of the super martial arts era, and a supreme super martial arts technique called "Tian Mo Ce" appeared in his mind. After resurrecting his life, how will Ling Yu change his and Xuanxuan's fate? Will the fate of the entire Earth Star human race change? Will Ling Yu in this life turn into a demon king like he did in his previous life?
