Shen Tiandong is on the verge of dying from illness, but he gets lucky and acquires a magic door that can travel between martial arts worlds.
With the door at his disposal, he tricks his way into the Tomb of the Living Dead and learns the martial arts of the Quanzhen and Ancient Tomb Sects, as well as the Nine Yin Manual.
It doesn't matter that his body is weak and sickly, or that his internal energy advances slowly. He uses the Divine Condor to power up, making his inner cultivation advance by leaps and bounds.
He steals Yuan Chengzhi's red-eyed ice toad.
He saves Fan Xian and Teng Zijing on Niulan Street.
He snatches the thousand-year-old fire turtle's inner core from Ma Junwu, and Bai Yunfei and Lan Xiaodie gift him the Secret Manual of Returning to the Origin.
He offers guidance to the young Dugu Qiubai, crosses swords with Ximen Chuixue, claims Ye Gucheng's Tianshan snow lotus, and visits Heroes' Island...
And then there's Fei Jishi, Ping Yizhi, Hu Qingniu, Wang Nangu, Doctor Mei Er, Xue Muhua, Cheng Lingsu, and even Confucian Sword Immortal Xie Xuan, Dark Sword Immortal Zhao Yuzhen, and Snow Moon Sword Immortal Li Hanyi...
As his martial arts grow stronger, these precious medicines, renowned doctors, and experts appear before him one after another.
