Review Detail of CrystalRust in Academy’s Undercover Professor

I've read until chp 136. The premise is interesting. The MC is complex. He has many identities. He is very determined and have high self control. His goals are simple but hard to achieve. There are many characters aside from MC that push the plot, there's a lot of mystery to be uncovered. I like that MC is truly unique and managed to excel inside the world. It's funny how he is panicking inside but he maintains an intimidating aura. This work is one of my faves, it's been long since an update tho.
