Lin Tian was abducted in his childhood, wandered foolishly for twenty years, and risked his life to save Xiaobao, the younger brother of Shen Group CEO Shen Qingtang. Shen Qingtang presented him with a heavy fortune and a black card to repay the kindness, and sent people to protect him secretly. Returning home, Lin Tian's greedy eldest brother Lin Qiang harmed him to seize money, but an impact caused his blood stasis to disperse and restored his sanity. Breaking off ties with Lin Qiang, Lin Tian accepted Shen Qingtang's invitation, disguised himself as an ordinary person to lurk in the Shen family, and fought against the second uncle Shen Jianxun who plotted for the family property. He defeated the opponent's assassination conspiracy, exposed all his crimes, and awakened Shen's father with ancestral medical skills. Indifferent to wealth, Lin Tian and Shen Qingtang fell in love with each other, joining hands to guard the Shen Group.
