Others work themselves to death, but Hua Mengmeng accidentally binds to a lying-flat system, recruiting people from other worlds to build an exclusive manor deep in the mountains. Traveling back and forth across myriad worlds, modifying history, and reducing regrets for people in another spacetime. Accompanied by the system, helped by big figures, and guarded by spiritual beasts, one can enter immortal cultivation above, modify history below, embrace the galaxy across the stars, and experience a different laid-back life.
