Aizen was a master at flirting with girls when he was young. After seeing through the mortal world, he went to Wuming Mountain to learn Taoism.
Through yin and yang, he becomes a brother to the Lord of Hell.
Later, his master arranged for him to go down the mountain and go to college in Donghai City.
When meeting Bixian, Aizen asked: "What is your score in mathematics in the college entrance examination?" Which made Bixian cry.
Others raise ghosts to harm others. Aizen subdues ghosts to wash dishes, do homework, and practice games.
When others invite the Patriarch, the incense is not enough; Aizen invites the Patriarch, and the first thing the Patriarch says when he comes down is: "Brother, who should we beat this time?"
When Wannian Ligui saw Aizen, he knelt down and shouted "Grandpa!"
Are they evil? Aizen is even worse!
