System Time Travel, I Am the Boss Behind the Scenes

I am tired of living and want to die for fear of pain. So, I burned three incense sticks that were taller than mine, worshiped one hundred and nine gods, and finally traveled through time. I brought history books, instructions for making sulfur soap, and I even got a recipe for gunpowder proportions! But can anyone tell me why! ! Is the world I traveled through a game world? Okay, okay, system, if you don't give me a way to survive, then I will have to make my own. After twenty years of fighting monsters and leveling up, you are still a teenager when you come back? Do you think I will be convinced by this? Tell you! I won't! My destiny is up to me! Waste! I've done enough! !
