The Last Disciple Episodes 1-3 Eng Sub

The male lead, Li Huan, is fleeing from the pursuit of the Demonic Sect while carrying his gravely injured and unconscious master on his back. At the critical moment, he entrusts his master to his subordinates and stays behind alone to hold off the enemy.
After severely wounding two members of the Demonic Sect in succession, he unexpectedly encounters the ultimate villain—the Demon King who brings chaos to the world. Just when he believes he is about to die there, he discovers that the Demon King actually intends to use his physical body to house his own soul.
At the very moment when the soul-transferring ritual is about to be successfully completed, Li Huan suddenly vanishes into thin air.
When he opens his eyes again, he finds that he has returned to ten years earlier!
