Ye Chen's heart was shaken intensely, just as life and death are, the ultimate form of life leads to death, the ultimate form of death leads to life; everything can transform into each other like Yin Yang.
If an eternal existence gives birth to the endless Chaotic Sea, this proves that chaos can, in turn, transcend eternity.
Moreover, the words of the Ancient Great Emperor further convinced Ye Chen, for he said thus: "It is said that the Emperor Supreme Saint is the closest person in history to achieving the Great Perfection of Chaos Dao. Why has there been more than one strongest Emperor throughout epochs, yet only he is the closest? Because he obtained the Eternal Crown, perhaps by using the power of the Eternal Crown, he infinitely approached the Great Perfection of Chaos Dao!"
Indeed, the Ancient Great Emperor's words make sense; Ye Chen even believed this was most likely the truth.
