I Hand Over the Wasteland from the Start, and the Ancestor Rushes to Stock Up Overnight

[Subverting expectations + an entire family transmigrates together + interplanar colonization + unstoppable farming + Fourth Calamity] Gu Yuan is the divine son of an immortal cultivation clan with a long legacy. His family has just one creed: whatever you see is yours to take, and whatever you take is private property! One day, he awakens the [Doomsday Savior System] and is tossed into a wasteland crawling with zombies. The System shrieks: “Host, run! A fifth-tier mutant Zombie Emperor is up ahead. Touch it and you die! Mission objective: survive for 24 hours. Reward: one crate of expired bread!” Looking at the zombies howling across the city, Gu Yuan brushes off his sleeve in disdain. “Survive? Think bigger.” He pulls out a cross-realm communication talisman and tears open the void. “Second Uncle, stop refining pills! We’ve found a huge supply of ‘tireless, unpaid, super-strong’ humanoid materials here. Send a hundred thousand beast-controlling bags over to pack them up!” The next moment, the immortal gates swing open and warships blot out the sky! The cultivation world’s top construction crew has arrived in the wasteland! And so the apocalypse takes an unexpected turn: [Zombie World]: The Zombie Emperor is placed under an ancestral restriction, slapped with a Divine Movement Talisman, and made to push a grindstone at the mines around the clock to generate power. Survivors move into the “Spirit-Gathering Neighborhood” and sign three-hundred-year mining contracts in tears. [Frozen World]: The Snow Queen is captured and put to work in the Gu family’s ten-thousand-mu spirit herb garden
