Lin Chen comes from a poor family. He has a tough and ruthless character but values love and justice. He is young at the beginning but has a fierceness that refuses to admit defeat. He has counterattack potential, a strong photographic memory, a lost business handbook left by his grandfather, and an industry insight that surpasses his peers. When he is down, he encounters the advice of a hidden boss. He has a clear bottom line, becomes stronger when he is strong, and fights back directly when facing injustice. The grassroots' road to change their destiny against the odds, the counterattack in a desperate situation, the resourcefulness and bloody spirit in business wars, brothers working together to overcome difficulties, the responsibilities and choices in growth, focusing on the core sense of "little people counterattack and slap in the face" and "standing firm in the jungle".
