the veteran equipment manufacturing company lushan heavy industry is in business difficulties. chairman fang ruizhou has been trying hard to launch the "heavy industry for finance" plan, but was disrupted by wei cheng, a young scientist with a weird personality. wei cheng firmly believed that the "lushan no. 1" he developed can kill two birds with one stone, not only save the company from falling, but also reveal the mystery of his father's crazy accident caused by a crane accident. however, he did not know that behind "lushan no. 1" not only is the great secrets and pains of the previous generation hidden, but also faces a life-and-death crisis of either subsidence or death. the international industry giants used open and secret arrows to try to use the same trick to block lushan heavy industry's neck. under heavy pressure, the internal boycotts in lushan are not only insidious, but wei cheng's team is in turmoil, and the future of "lushan no. 1" is uncertain. at the critical moment, wei cheng's model worker mother song chunli and his happy enemy jin yanzi - the representative of lushan heavy industry's two generations of technical madmen - used their influence among workers to give key support. fang ruizhou, who was both enemies and friends with wei cheng, also took the initiative to retreat and endure it. in the struggle, wei cheng gradually realized the power beyond technology. this power made him truly understand the meaning of perseverance and the value of inheritance, and also mastered the secret of competing and cooperating with powerful opponents. he and the new generation of workers finally stood at the peak of the industry that his parents longed for, and what greeted them was not only infinite glory, but also endless challenges.
