我可以修改万物时间线

What should I do with these expired elixirs? Don’t worry, I can revert it back in time, so give me all of your expired elixirs! What should I do if my cultivation process is too slow? Don’t worry, I'll just shift the cultivation time forwards by about five years, so it'll look like I mastered the cultivation technique right away. What if I get hurt? Don't worry, I'll just revert time back to my body's healthy state, before I got hurt. What happens if I transmigrate to a new world as a weakling? Don't worry! I can change the timeline of everything! (Source: Tencent, translated)
