You Get a Mentor System at the Beginning, and You Have to Pick up Apprentices

On a piece of yellowed parchment it was written: The mighty evil things tore through the space and came. The long-famous Taoist immortal sects fell one after another. The 'pillars' tried their best to resist but they were unable to resist. An unknown secret sect stepped forward to turn the tide. Its disciples were possessed by murderous gods, making enemies tremble as soon as they entered the battlefield. The leader even sealed the sect with one finger, locking out all alien races. After the battle, the three thousand worlds ushered in ten thousand years of peace. No one in future generations would dare to forget the instigator of all this - Du Heng.
