I Become an Immortal Emperor Through My Disciples

Gu Beihan traveled to the fantasy world for seventy years but never entered the path of immortality. On his deathbed, he awakened a disciple collection system that grants ten thousand times return and life span rewards for every disciple taken in. By chance, he accepted the severely injured Su Qingyao as his first disciple. Subsequently, he took several female disciples, causing his life span to grow and his power to increase. The Tianhe Sect and the Crimson Blood Sect both sent challenges, but Gu Beihan decisively defeated them all.
