In Chinatown overseas, the abuse of AI chips gives planters super combat power, and order is on the verge of collapse. Lin Zun is murdered, Lin Industries is attacked, and Lin Feng, who left home, returns to repel the villains. Sister-in-law Man Li is actually the only survivor of the chip R&D family, hiding her name to hunt down the killers. Assisted by Shen Qingyao of Longmen, Lin Feng finds out that Lin Zun died of the secret technique "Blood-Breaking Needle," and the killer is within. He tracks Lin Shaojie's illegal chip transactions, and after an entrapment by his ex-girlfriend Xu Wei and Man Li being kidnapped, he rescues her and exposes the mastermind, second uncle Lin Yaozong. Lin Yaozong harmed Man Li's family, killed Lin Zun, and implanted the ultimate chip. Lin Feng defeats the chip computing power with his martial arts original intent, and the police arrest the father and son. Man Li reorganizes Lin Industries, and Lin Feng bids farewell to return to his place.
