The reason Ye Huan was so confident was that the Shanhai World currently lacked the Dao of anything above level 99 Pseudo-Zun. In other words, even if Chen Dong returned, he would be unable to use the Dao of Time beyond level 99 Pseudo-Zun.
However, just as Ye Huan was about to begin his study and cultivation, Dacihua suddenly called: "I know you’re likely practicing the Dao of Time and shouldn't be disturbed, but there is something I must tell you: Chen Dong is back!"
Ye Huan was flabbergasted. He hadn't even finished learning all the applications, martial arts, finishing moves, and secret techniques related to the Dao of Time hidden in those 18 boxes, and already Chen Dong had returned! The timing was too coincidental.
