Only Those Who Can Teach Mediocre People to Excel Are Considered Masters!

Lin Bufan traveled through the world of immortality and was bound to the "Master System". As long as he teaches his apprentice, he can obtain the corresponding cultivation level and easily improve his strength. However, when he started to accept apprentices, he did not expect that the system would not recognize any talented apprentices and would only count the ones he accepted as real losers. "Geniuses still need you to teach them? Only a master who can teach useless people to become talents is a true master!" He had no choice but to follow the system's ideas. After all, no matter what, it would be faster than practicing on his own. But he soon discovered: The system seemed to have a more ambitious goal, and teaching disciples was just a facade? There is no heroine. The protagonist is not violent and will not kill at every turn. Readers who like to read "kill decisively" plots should beware.
