Lin Mu had entered a trance and had no sense of time.
While this was a little troublesome, it was also beneficial to him at the same time. His Dao Embryo that was floating in the Dao Shell in front of him kept on expanding slowly. Millimeter by millimeter it, grew.
Such was the Embryo Growth stage of the Dao Treading realm.
The more one's Dao Embryo grew in this stage, the better their comprehension of the Dao Traces would be. And the more they comprehended the Dao Trace the more their Dao Embryo would grow.
It was a looping cycle that started slow but sped up the longer one managed to maintain the state.
Lin Mu was in that condition. Perhaps it was because he was in a high leveled Immortal world that was on the precipice of World Ascension, the Dao Traces were very active. Lin Mu was progressing at a shocking pace and so was his cultivation base.
