Returning to the Cambrian, I Build My Home in a Snail Shell

[Invincible + Rebirth and Revenge + Doomsday Farming + Exotic Pets + Stocking Up Supplies + Creating Forces + Multiple Heroines + Decisive Killing] The arrival of the leech fog ushered in an era of great explosion of organisms across the world. Animals and plants are growing crazily, all kinds of mutated beasts are rampant, and humans are reduced to the bottom of the food chain. The rules of nature have changed, and exotic pets have become the primary productive force. Mo Xuan returned from rebirth, seized the opportunity, contracted with the Xuanyue snail, and built a doomsday mobile giant city in the snail shell - Xuanyue City! Countless supplies, a unique living environment, and a superior identity. Unknowingly, Xuanyue City became a holy place in the hearts of countless people in the last days of Cambrian. The men struggled to get a chance to enter the city. The women put aside their reserve and tried every means to marry a man from the city. As the controller of Xuanyue City, Mo Xuan only needs to raise his arms and make thousands of goddesses fall into his trap!
