Please Sign for the Old Civilization

Lu Xiaoming came to the dock to repair the pump, but before the pump could be repaired, the dock collapsed first. My cousin was pressed under the beam, and my friend drank a lot of river water. He found a wristband from the old cabin that could use materials and energy to reconstruct the machines of the old civilization. There is a copper deficiency at the moment. Lu Xiaoming pried off the bronze medal engraved with "Those who privately reveal the remains will be sentenced to ten years of hard labor" and threw it into the blue light. "I accept ten years of hard labor. Someone fish it out for me first." A maintenance robot named Mengmeng stood up. It will save people, check faults, and remind him: the sleeve is borrowed, please do not lose it. Lu Xiaoming originally wanted to earn some money from this craft, buy medicine for his master, repair Mengmeng's leg, and pay off the money for the copper wire recorded in the police station's account. But as the machines became more and more repaired, someone offered him a huge price to buy the right to repair things for whomever he wanted in the future. At the same time, the hatch of an old boat was exposed at the bottom of the river. It contained energy storage equipment that was being fought over and an unfinished delivery order. Everyone is valuing the cargo. Lu Xiaoming wanted to find out first—— To whom were they originally intended?
