I Traveled Thousands of Times to Save the World, but Humans All Wanted to Kill Me

"Despair + Sadness + Darkness + Not Brainless + Unhappy Writing + Not Systematic" He believed that being able to travel back and forth between the ancient world of immortality and modern times was the only hope to protect his sister Lin Yong'an. He recruits apprentices and teaches skills in the world of immortality, hoping that his disciples can help him fight against chaotic monsters in the modern world; he uses ancient formations to defend the human base, just to give his sister a refuge. But he didn't expect that Mo Chen, the eldest disciple who taught him everything in ancient times, would shoot his heart through the heart in the modern era and push his sister into a pile of monsters; Su Qing, a medical practitioner who once said that his master was the best "family", would tie him to the experimental table and torture him with electric shock, and put his sister under house arrest to force him to "confess" his crimes; After repeated deaths and betrayal, he finally understood: Humanity has never wanted to coexist, but to use his sister's immortal bloodline as a sacrifice; restarting the world will not bring hope, but will only turn the world of immortality into a hell of "annexation and advancement"; he taught his disciples "guarding", but only raised a group of crazy demons who wanted to eat him. When the sister was tied to the altar, there was no savior in the world, only the World-Slayer Demon. "You want to sacrifice? Okay, today, except my sister, no one of you will survive!" On the day when blood flooded the altar, he fought from dawn to dusk, with no one behind him and the only light in his arms.
