Zhang Weiben was a delivery boy in the city. He delivered food in the wind and rain every day. His life was monotonous and difficult. While delivering food, he encountered an accident and traveled into the unopened chaos of heaven and earth. It was pitch dark here, and the energy of chaos was raging. Zhang Wei struggled to survive, and accidentally witnessed Pangu's feat of creating the world. In that earth-shattering scene, Pangu held a giant ax and struggled to split the chaos. The clear air rose to become the sky, and the turbid air sank to become the earth. After Pangu fell, Zhang Wei was lucky enough to obtain Pangu's legacy. His body was greatly transformed, and he gained powerful strength and special talents.
After obtaining the legacy, Zhang Wei continued to practice in the chaos, and his strength gradually improved. When Patriarch Hongjun was preaching in Zixiao Palace, Zhang Wei materialized and attracted everyone's attention with his unique temperament and extraordinary origins. With his firm will and unique understanding of Tao, he successfully became a disciple of Lao Tzu, one of the Three Pure Ones, and became his direct disciple.
