Feng Wuchen couldn't be bothered to do thankless tasks.
The alchemists who stayed behind were all God-King Level and Divine Monarch level, not many in number, just over thirty.
Thirty or so alchemist students, that's not too many.
Of course, Feng Wuchen couldn't guarantee whether all of these thirty or so alchemist students were willing to learn from him.
Feng Wuchen looked at those thirty or so alchemist students and asked with a faint smile, "Since you stayed, can I understand it as you being willing to receive my instruction?"
"Our alchemist realm is not as high as the Chief Mentor's. Since the Mansion Master has appointed you as the Chief Mentor, we believe you can guide us," a female student remarked respectfully.
"The Mansion Master and the elders all trust the Chief Mentor, so we trust the Chief Mentor too," another student said.
"Chief Mentor, if your skills aren't up to par, we won't accept you," a student stated.
