Lin Feng, a battle king and miracle doctor, comes to Shangjiang City on his master’s orders to care for his master’s sister and break off his engagement with unseen fiancée Zhou Mengxue, CEO of Shengya Group. That night, he saves Zhou Mengxue from a poison plot and removes her cold toxin, but she wakes and accuses him of assault. Police get involved.
The next day, Lin Feng meets Situ Wanjun, Shengya’s Chairman, with his master’s jade pendant, and proposes canceling the engagement. Zhou Mengxue refuses, but after seeing him instantly subdue criminal Baolong, she hires him as driver and bodyguard for a million yuan a year. He then foils Chen Yin and Sun Qian’s power grab, saves drugged Situ Mengyao, kills Sun Qian’s Hyena Trio, and uses lost Fuxi Nine Needles to save Yuan Qingting’s dying mother. Su Jing helps, and Shengya survives.
Sun Qian colludes with undercover Yuan Qingting to sow discord. Lin Feng resigns. Zhou Mengxue is kidnapped to an underground lab. Yuan Qingting repents and asks for help. Lin Feng kicks open the titanium door, rescues Zhou Mengxue, and exposes Sun Qian’s patricide and power grab. With Su support, Zhou Mengxue counterattacks; Sun Qian’s stepmother Zhang Yulian publicly testifies. Lin Feng, as Medical Saint Naihe, backs Shengya, destroys Shangqing Group, and Sun Qian is jailed.
At the celebration, Situ Wanjun announces Lin Feng and Zhou Mengxue’s renewed engagement. Desperate, Chen Yin drugs Wanjun, forges a marriage certificate and share transfer, and tries to seize Shengya. Wanjun jumps from a building rather than submit. Lin Feng saves her with miraculous medicine, then storms the shareholders’ meeting in mourning, exposes Chen Yin’s schemes, and kills him. The final battle between the Zhou family and Xingyun Gang begins.
