Travel Through Another World to Open up Wasteland

One day, a space was found out of nowhere, so Tang Xiaoruan spent all his money over the years to buy travel equipment, packed all the belongings in the rental house into the space, packed a bag on his back, and left. Until that day when I fell off the cliff and traveled to another world, I thought it was a primitive world, but I didn't expect it to be a world of beasts. I thought it was just a sweet couple spending their time peacefully. Unexpectedly, a severe drought struck. The earth was parched and no grass could grow. What on earth were you going to do? To escape this disaster.
