The Best School Doctor

A ring that looks like a plug-in modifier. As long as you input the obtained code into the ring, you can get the corresponding abilities. There are all the martial arts codes for the Nine Yin and Nine Yang Yi Jin Jing, the code for seeing through invisible walls and clairvoyance, and the code for the ultimate weapon to destroy the heaven and the earth. In short, I have the code in hand, and I have the world. It's a pity that these codes are not easy to obtain... Chen Mo was framed and turned into a homeless dog. After escaping, he obtained the artifact ring and became a glorious school doctor. I can do what the principal dares to do! I dare to do things that the principal dare not do! Solemnly declare: This book is green and natural, and is suitable for all ages. Of course, there are absolutely no plots that are inappropriate for children!
