Three Days to Live, Getting Stronger by Taking Disciples

In his past life, Lin Xuan was the top assassin feared by all, but was betrayed by his organization and died with regret. Reborn as the laid-back ancestor Lin Xuan of the Yuantian Sect in the cultivation world, he finds his dantian shattered and cultivation wasted, reduced to a mere figurehead. Resigned to idling away his remaining lifespan, he unexpectedly binds with the [Apprentice System] fifty years late. The system gives him no beginner benefits, only a death order: take a disciple within three days or die. Forced to survive, the lazy ancestor reluctantly starts teaching in his own unorthodox way. While other masters teach with strict doctrines, Lin Xuan improvises and rambles. Unbeknownst to all, his words become reality—his casual nonsense turns into supreme divine techniques, and his offhand guidance makes waste spiritual root disciples comprehend the Dao overnight. Everyone believes he is a hidden master, but Lin Xuan himself is bewildered. From then on, the lazy ancestor, with his inexplicable teaching, rises against the heavens and dominates the myriad worlds.
