Global Catastrophe, Survival in Caves

Illusion version ①: There is a global cataclysm and everyone is trapped in the cave. You start with a broken drill. If you want to survive, you must constantly dig channels and look for food. No one knows whether resources or monsters are waiting for them in the next cave. Jiang Hao was also forced into it, but he could see through it. [There is a valuable item in the third cave ahead] [Cave No. 1 Below is the resting place of a cave monster] [In the seventh cave on the right, a golden iron pickaxe was found] While everyone was still worrying about food, Jiang Hao had already begun to exchange excess food for resources. While everyone was still digging carefully, Jiang Hao was already fully armed and running rampant in the underground world. Real version②: A hundred years ago, the devil resurrected and the catacombs descended on the earth. There is a global cataclysm and everyone is trapped in the cave. In order to deal with the demons, Gaia, the God of the Earth, started the time traveler plan, allowing Jiang Hao to go back to the time when the burrows just arrived a hundred years ago, and eliminate the demons when they were in their infancy. But in fact, Gaia has to recruit more people to go back and serve as cannon fodder because of the insufficient survival rate of time travellers.
