The Most Powerful Apprenticeship System

Traveling through the world of cultivating immortals, you can get generous rewards as long as you accept a disciple. And, step by step, he became the most powerful existence. Is there any more pleasant existence than this? Before time travel, it was about harvesting traffic and realizing it, but in the world of cultivating immortals, it was about harvesting people's heads. As long as there are enough people, they can be extremely powerful. It's the same thing but the same thing! With this system, it is not about becoming the most powerful being.
