In his past life, Xu Erlong sold his housing cheaply and burned out his life protecting his father Xu Dongsheng, yet his father, who favored his cousin for a lifetime, left all property to his cousin Xu Damin, until Xu Erlong was told the truth and died with everlasting regret. Reborn back to 1882 on the day before going to the brick kiln to carry bricks to fund his cousin's tuition, Xu Erlong decisively split the family and refused to be a "cousin-support demon" anymore. Relying on his business mind, from reselling soft-shelled turtles and eels to opening a leather shoe store, he led his mother Zhang Jinfang and younger sister Xu Xiaoling toward independence and prosperity, and protected his past-life love Wen Ye, rewriting the trajectory of his life.
