Perfection: Immortal Era

The protagonist traveled through time and became a genius at the end of the ancient Immortal Era. He knew the outcome of the Immortal Ancient's destruction in advance and tried to find a way to break the situation before the era was overturned. However, he found that no matter how hard he struggled, he could not shake the established historical trajectory. Everything he did eventually became part of the "should be" in the legends of later generations. A preacher (a quasi-immortal king-level existence) from the Immortal Realm came to the nine heavens and ten places. He was both a savior and an observer, witnessing and participating in the beginning and end of the Immortal Ancient's destruction.
