Immortality Starts from Reloading Files

Lin Yuan traveled through time and became a blood slave under a disciple of the Demon Sect. He was unarmed and had zero realm. After being brutally trained in the blood elixir, Lin Yuan returned to the time when he had just traveled through time. Only then did Lin Yuan realize that he could go back to the time before his death with his memories. Many years later, when Lin Yuan looked at those people who respected him as the Emperor of Heaven, he fell into deep thought. At first, he really just wanted to survive.
