After his rebirth alters the timeline, the protagonist faces more dangerous acid rain that accelerates zombie mutation and strengthens them. Freya warns that prolonged rain exposure could cause zombies to evolve further. To prevent an escalating threat, he activates a turret and successfully eliminates a zombie attacking his window. This victory unlocks a seed shop in his Pocket Dimension Farm, where he chooses offensive crop upgrades to boost combat power. Transforming his RV's third floor into a special crop farm, he organizes plots for vegetables, fruits, and animal feed. Just as he settles into farming, a government message arrives, bringing a new sense of danger.
