To date, the demon lifespan Shen Lin had spent comprehending True Dao Fusion had long since exceeded the lifespans of most Dao Integration Realm experts themselves.
Every living being had a different lifespan, limited by its race.

They could only rely on the disparities between the Great Daos they had mastered to unleash True Dao Fusion methods.
After all, unlike Shen Lin, they did not have so much time to study them painstakingly and completely master the full methods of True Dao Fusion.
Perhaps it was for that very reason that the True Dao Fusion realm Shen Lin had cultivated to now was a realm almost no one throughout the River of Time had set foot in.
