During the battle between the real and fake Monkey King, Tathagata felt that Sun Wukong was out of control and had his own thoughts, so he helped the six-eared macaque to beat Sun Wukong to death with a stick and crush his bones into ashes. In addition, Sun Wukong could never be reborn, so he replaced Sun Wukong with a six-eared macaque. Assisting Tang Monk to go to the West to obtain Buddhist scriptures, the late Taishang Laojun failed to save Sun Wukong, but with the power of the master, he preserved a trace of Sun Wukong's spiritual consciousness, and re-sealed the spiritual consciousness in the fairy stone in Huaguo Mountain to treat the destined people in future generations.
