Legendary Hunter Starts with Infinite Rewind

Kern von Oberon, 147 years old, mixed race, legendary hunter K. He was once a man who stood at the top of the continent, and all his enemies were dead souls killed by the sword. Until he was jointly strangled by the disciples he personally trained, and the six pieces of the supreme demon king's body were divided up. Those white-eyed wolves stepped on the bones and blood of their mentor and became a master. Then, he opened his eyes in the ICU. After being in a coma for five days in a high school car accident, he thought he was having a 147-year dream. Until today, many years later, when I mentioned my luck again on the way to work, when I opened my eyes, I was back to the resurrected K. But this time, he has mastered a new ability-death retracement. Save at any time, automatically return to the save point after death, keep the memory intact, and reset the body without damage. Kill the wrong person? Start over. Regret it? Start over. The information is broken? Start over. However, every time you load a file, the enemy will have a vague sense of déjà vu, and the world line will also change unexpectedly due to the butterfly effect. At this moment, the stern father of the traitors returns grandly... "Next, I'm going to take back what's mine and take away what's not yours."
