After a Thousand Years in Seclusion, My Sect Has Moved?

[Urban Cultivation + No System + All-Rounder + Single Female Lead or No Female Lead] When Ye An emerges from seclusion, he discovers that the times have changed and his sect has vanished without a trace. Unable to survive his heavenly tribulation, he has no choice but to use a secret technique to evade it. In the end, he is transformed into a child, with only three years to regain his cultivation. He is no Bodhisattva, yet he refines pills and medicines, treating the sick and saving lives. He is no demon from hell, yet he strikes without mercy and treats human lives as grass. He only wants to find his master, but ends up defying the Heavenly Dao and bringing about a spiritual qi revival, restoring the cultivation world to its former glory. He only wants to complete his karmic cycle, but ends up rebuilding his sect’s former glory.
