Taiching Laozi heard the words but shook his head involently: "My method is not easy to learn. Your strength cannot withstand the backlash of cause and effect. To intercept a certain timeline, to replace a Great Divine Ability being, and to craft all kinds of myths and legends on the timeline you create, one must bear the corresponding cause and effect!"
In fact, the timeline he intercepted, the Great Divine Ability being he replaced on that timeline, were all beings that had established cause and effect with him in the Primordial World.
Yuanshi Tianzun and Tongtian Sect Master go without saying; The Three Pure Ones originate from the same source, and Fu Xi, who has a master-disciple cause and effect with him in the timeline of the Primordial World, Xuan Dou becoming the Heavenly Emperor's teacher was indeed on his master's behalf.
