Borzhijin Tiemu was reborn as an ancient tree in the mountains of Beili, and Ma Chengyu was reincarnated as a boy in a border town. Their fates were intertwined due to the "symbiotic binding" of the two systems. One takes root in the soil, perceives the world and nurtures vitality with the ability to cultivate people forever; the other travels across the rivers and lakes, develops martial arts with the practitioner system, and travels all over the world. They share perceptions and complement each other's weaknesses. From the life-and-death dependence of Black Wind Ridge to the involvement in rivers and lakes disputes and dynastic secrets, in this Beili world intertwined with martial arts and fantasy, one person and one tree are each other's armor and a common weakness. When the truth of rebirth emerges, they will eventually carve the legend of "twins" in this land in a unique way.
