The nuclear bomb overturned the wasteland, Yan Ci's emergency mecha was trampled into scrap metal by the enemy, and blood oozed from the cockpit. On the line between life and death, he screamed out the sentence that would be regarded as a nightmare by all the strong men in the future: "If the mecha is broken, don't come to me to repair it, come to me, you have to pay more!" The next second, silver light suddenly appeared in the wreckage - he closed his eyes and used his bare hands to push the paralyzed power core back to its original speed. The base that abandoned him in the past begged him to come out, and the top technician who stepped on him in the past self-destructed his mecha in front of him and begged for advice. And he just opened the maintenance log and said calmly: Place an order and receive a doomsday quote.
