Zhang Xianfan was transformed into an abandoned baby in Longhu Mountain in the world of "Under One Person", and was picked up and raised by the Heavenly Master in the mountain. It takes others ten years to practice the Golden Light Mantra, but he can do it at a glance; when others want to draw thunder and burn incense and pray, he raises his hand and it is the divine thunder. Eighteen years later, the Heavenly Master sent Zhang Lingyu to "discuss" - but Zhang Lingyu struck with all his strength and was pushed into the ground by his palm. The old Heavenly Master hid behind a tree and peeped, and even Lu Jin couldn't count ten of them. Finally, the Heavenly Master asked him, "Do you want to go down the mountain and meet your nephew Zhang Chulan?" Zhang Xianfan said, "Okay, let him take over as the Heavenly Master."
