When the red mage Lei Zang in The Magician traveled to infinite terror, he replaced Li Xiaoyi and joined everyone in the adventure...
Raizo:
The first BOSS in Xiu Dou was unable to open his eyes because the Demon King was sealed in his soul. In order to cure his own eyes, he continued to conduct experiments on other people, and thus gained the name of a sage. A person who would do anything to liberate the devil in order to open his eyes and see the world. Proficient in astronomy, geography, medical alchemy... It is an active encyclopedia. And he is a scientific madman who can turn his great-great-grandson into a synthetic orc at will for the purpose of experiments... (The more I talk about it, the more I feel like why he looks so much like someone)
