Lin Yuan is a scavenger at the bottom of Rusty Harbor and an awakened out-of-control machine core wanted by all city-states. His negative emotions will amplify his power, and once it exceeds the threshold, he will go berserk and destroy everything around him. In order to survive, he picked up discarded parts on the black market every day, but accidentally activated the dimensional shuttle door in his body. On the other side of the door was a deserted farm where "causal fiber" could be grown. Causal fiber is a scarce resource for mecha combat, and it is also the only hope to repair the out-of-control machine core. Lin Yuan started farming in a Buddhist style: turning the soil, sowing seeds, and harvesting with mecha weapons. When he harvested the peace grass seeds for the first time and successfully suppressed the rampage, Lieutenant General Black Horn who was chasing him broke in with the mecha troops of the Abyss Order. Lin Yuan activated the farm defense system - the causal fibers he planted turned into turret chains, blasting the Lieutenant General's mecha formation into scrap metal. News spread that the Iron Covenant and the Abyss Order were eyeing him at the same time. They thought that Lin Yuan had mastered the ancient machine soul legacy, but they didn't know that he was just a scavenger who wanted to farm steadily. Mr. Anvil sent rare seeds, Red Fox blocked the fatal blow for him, and Hoshimi taught him how to control his emotions. However, Granny Dreamweaver's betrayal caused the farm to fall for a time, and Lin Yuan was forced to go on a rampage again. In the end, he chose to pull all his companions into the farm and use a farming feast with everyone's participation in exchange for an ending that healed everything.
