How to Use a Time Machine Correctly

You start with a time machine, and it's up to you how you want to use it. Xu Wenyuan said that this feeling is really awesome. Not satisfied with the exam? It doesn't matter, just go back and take the test again with your perfect answers. Can't catch the goddess? It's very simple. If you attack her when she was a child, the goddess will fall directly. Not enough money? Don't worry, if you go back and buy more lottery tickets, you'll win. You'll have more money than you can use up. The enemy wants to do something bad? It doesn't matter, go to the future and buy some cross-era weapons, and stand up if you want to die. Is there any danger in traveling? Don't be ridiculous, the more the protagonist travels, the more powerful he becomes. The time paradox makes me stronger. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
