Kill Everyone in the Future

Hello, I am Xiao Wang. Ten thousand years ago, I was left in ancient times by a time traveler. Ten thousand years later, I finally waited for my "master" - an ancient martial arts champion who was hit by a truck. He had no water, no food, no equipment. He doesn't even know where he is. What can I do? I can't do anything. I have no combat functions, I can't find water, I can't heal. I can only tell him: Go 17 kilometers southeast, there is a groundwater enrichment area there, the probability is 37%. He actually believed it. He actually went. He's actually not dead yet. This story is about how he became the hope of a group of people in this bullshit future world, using ancient martial arts and an AI that only told bad jokes. If he hadn't been fooled to death by himself halfway.
