Review Detail of in Arcane Academy: The Divine Extraction Legacy

This novel world background is great. The writing quality and updates are all excellent. till chap 80 I loved this novel. But mc is a dumb idiot. He kills a 13 or 14 years old just because headmaster asked him and for his favour. He also let others misunderstood him and didn't care on explaining. The system also has little use as mc sometimes forgets about it.
