You Asked Me to Manage a Class of Good-for-Nothings, So How Did I Become the Demon Cave's Boss?

[Not an all-out fast-paced story. It has slice-of-life elements, and the demon lords aren’t truly evil!

[Ding! The Strongest Mentor Lottery System has been activated!] [Copy your students’ skills and magical treasures to reach the pinnacle of mentorship!] Ye Chuan: (.) He prepares himself for a classroom full of spoiled young masters and ladies, but gradually discovers... Damn it! They’re all demonic cultivators?! But Ye Chuan refuses to give up.

Several figures appear behind him in an instant, their demonic aura more powerful than the beasts’, and the pressure of their max-level Evil Martial Gods erupts.
