Su Mo was reborn in the educated youth center of northern Shaanxi in 1975, holding in his hand the transfer order he had just received to return to the city. In his previous life, he had made a mess after returning to the city, and even brought trouble to the fellow villagers who had helped him. This time he tore up the transfer order on the spot, and also had an "Aura Auto Repair Tool Kit" in his pocket. The wrench can absorb Aura and the screwdriver can detect machine faults.
The tractor in Educated Youth Point broke down, and the commune technician failed to repair it for three days. Su Mo used the "spiritual energy detector" in the tool kit and found that the engine lacked spiritual energy lubrication. When he pushed a wrench, the tractor sputtered and ran away (accidentally blowing the chimney away and hitting the commune secretary's straw hat). He helped fellow villagers repair water pumps, modify millstones, and even used spiritual energy to repair windows at the village primary school. The children called him "Su Shenxian." Someone reported him for "doing evil things", but the efficiency of the machines he repaired doubled, and even the county agricultural machinery station came to invite him to give lectures. From ordinary young people who want to return to the city, to "cultivation technicians" who take root in the countryside, the "spiritual farm machinery blueprints" that occasionally pop up in their tool kits make him discover that the machines of this era hide the secrets of cultivation.
