Ai'er

Plot
Ai'er was first revealed to be kidnapped by experts from Asura Association, who wanted to sacrifice her blood to the Asura King while recording it. Ye Fan was just around and found it convenient and tailed the car to the Asura's hideout in a church. He killed every single one of them and saved the princess, who seem to not be scared of the deaths of the experts. Taking the princess to a safe place, they were ambushed by the Asura's experts once more. After fighting off the experts, Ye Fan was surprised to see that the princess has disappeared.

Coming to China, the Princess escaped from the Palace to meet Ye Fan in Hua Hai. She first urged Ye Fan to be her tour guide across Hua Hai, but later settled for a gathering of Ning Zimo, Feng Yueying, Su Qingxue, Chu Yunyao and Wu Ye (Fog Night) at a lake close to the Purple Bamboo residence.

Their gathering was interrupted by one of the legendary rank expert, Pirate King, who wanted to bring Princess Ai'er back to her country. Ye Fan ended up fighting the Pirate King and defeated him on the water where he was most powerful.

Ai'er is the princess of some country as well as being the President of the Adept Association, which is responsible for taking care of mages with elemental prowess and mental strength.

On her birthday at her palace, the Doomsday King (Shakyamuni) sent Earth King and Void, who are fifth and third in the rank of disciples under their master, to kidnap the princess. The interference of Ye Fan and Sally Ye disrupted the kidnapping plan, leading to a huge battle at the palace which almost led to the death of Ai'er's parents, but was saved at the nick of time. This revealed Princess power to the both the king, who was shocked, and the people at the party. Ye Fan was close to ending the Earth King's life, but Void used his spatial powers to save the fifth-ranked expert. Void then started his battle against Lucifer and it ended with him being banished to some other part of the earth where Lucifer met with Void sister, a chief elder of Underworld Alliance. Princess was then kidnapped by Void, after threatening to kill her parents.

It was revealed that the Shakyamuni planned to maximize Princess Ai'er elemental powers to deal with Ye Fan, who is thorn and an oddity in his plan against the Divine Descendants. Some months after, an explosion happened in the subway station in Hua Hai where Ye Fan, his daughter and Mu Mumu was present. The explosion was caused by Ai'er who was seen to be struggling with herself, but before Ye Fan could get close to her, she opened her arms in a crazed state and made another explosion that caused the death of thousands of people in the city. Realising that some of her memories have been tampered with by the Shakyamuni, Ye Fan enlisted the help of Angel, whose body had been taken over by a holy god from another realm. Angel brought Ai'er back to reality after using her powers.
