Three hundred years drifted by.
For a domain, that span was insignificant. For the Immortal Sect, it was three centuries of rapid advances in cultivation science and technology. With the computational power of a Dao Integration-level soul behind it, the Immortal Sect achieved breakthroughs in multiple fields.
Two hundred years ago, in year 14796, all Nine Immortal Sect Scriptures achieved breakthroughs.
