Dao Ancestor Space, Dao Ancestor Reincarnation, and the other Supreme Dao Ancestors were clearly half a level lower than him and Xilin, but their actual combat strength was not much different.
Back then, Dao Ancestor Marvelous Light, who had been killed by him, Xilin, Dao Ancestor Space, and Dao Ancestor Reincarnation, had even more exaggerated combat strength.
If Dao Ancestor Marvelous Light had not failed and continued cultivating, he might really have a chance of becoming the Eternal Ruler of this universe.
Of course, the disadvantage of specializing in a Law was also very obvious. Overly competing for authority with the Universe's will in this universe on a single Law would definitely cause the suppression of the Universe's will. Therefore, these Dao Ancestors did not dare to use the Law Power fearlessly to prevent themselves from being assimilated by the Universe's will.
