Of all Li Che's clones across the many worlds, the ones progressing fastest were actually his two clones in the Desolate Era world and his Starry Clone in the Swallowed Star universe.
The situation in the Desolate Era world needed little explanation. A complete inheritance from a Second Step Dao Lord who had mastered a strongest dao left Li Che with an almost unobstructed path to becoming a Perfection World God.
