Rebirth of Prehistoric Times: Rewriting the Destiny of Calamity

At the beginning of the prehistoric period, Kunlun's abandoned disciple Su Yun was crippled because he broke through the saint's layout, and died miserably. After his rebirth, he awakened the 'become stronger when encountering the strong' system and the fate-rewriting function, and wandered through the inevitable calamity. After rescuing Hou Tu from the suffering of six realms of reincarnation, he rescued Yun Xiao from being trapped in the list of gods. Every time he rescued a person, he would receive a gift from his peak cultivation level. All the gods and Buddhas in the sky are pawns, but he used his mortal body to rewrite Hongmeng's destiny with his backhand, causing thousands of immortals to kneel down and beg for a chance of survival. Protagonist setting: Su Yun, a former second-generation disciple of Kunlun Mountain, was expelled from the master because he witnessed the secret of Yuanshi Tianzun's plan to measure the calamity. He is calm as ice, extremely vindictive and pragmatic. After his rebirth, he seemed to be a mortal with no cultivation, but in fact he had deep contempt for the old order in his heart. His driving force is not only to survive, but also to save those "tragic characters" abandoned by heaven, tear apart the cage of fate woven by saints with his own hands, and establish his own order in the flames of war between gods and demons.
