Adventures in the Cave

During the summer geological survey, we got lost deep in the mountains, and we hid in a mysterious cave. The deeper you go, the wider the space becomes, and you eventually discover an underground world that has been hidden for thousands of years. The residents here are actually descendants of immigrants from the ancient Central Plains and are being plundered by ferocious cavemen. With modern knowledge and teamwork, the three of us accidentally became the military leaders of the tribe.
