Lin Chen, a down-and-out auto repair apprentice in a third-tier town, accidentally awakened his mechanical affinity after inheriting the old street auto repair shop left by his master. He could sense mechanical failures, dismantle and reassemble them instantly, and even give machines special properties. Because he guards the auto repair shop, he has a grudge with Zhao Tianyu, the son of the president of a foreign car company, who covets the out-of-print modification blueprints and his special abilities. Lin Chen rose to prominence in a national car modification competition, met Su Qingyue, a graduate student in the Department of Vehicle Engineering, and turned from enemies into partners. With his special abilities and hard-core auto repair technology, he counterattacked all the way from a third-tier town to a first-tier city, resisted the suppression and business war plots of foreign car companies, broke the technology monopoly, and finally became a leader in domestic auto technology. He adhered to the original intention of "serving the country with craftsmanship" and created the future hand in hand with Su Qingyue. The plot combines a relaxed and refreshing slap-in-the-face plot, hard-core auto repair knowledge and warm daily life, and the rhythm is relaxed and moderate.
