Yun Yang, a mighty figure in the Tribulation Crossing stage for ten thousand years, dropped to the Qi Refining realm due to the exhaustion of heaven and earth spiritual energy and changes within his body. To find an opportunity to restore his cultivation, he disguised himself as a grassroots delivery driver in Jiangcheng to begin his mortal trials. By chance, Yun Yang went to see his centenarian old friend Huo Zhuxi for the last time, but ended up written into her will and chased wildly by her granddaughter Huo Siyun, the number one beauty in Jiangcheng. During the delivery process, Yun Yang befriended street brother Ma Hui and pure adopted daughter Feng Manran. Facing class contempt and threats from various forces, Yun Yang ignored all worldly rules, and with the posture of wearing the yellow robe, used unimaginable absolute force and heaven-reaching medical skills to crush them all the way down.
