Who is in Xia Dongqing's body?

Xia Dongqing is a character in The Ferry of the Soul. He has a pair of eyes that can see ghosts. After the "Red Moon", convenience store 444 disappeared from this world, and Holly's life seems to be back on track. He hopes to be a freshman. She was accidentally killed by a banshee, saved by Xiaoya, and later became a "wonder" in Zhao Li to survive. She has a big secret (Chiyou) inside her.

Extended data:

The reason why Xia Dongqing has Chiyou in his body: Xia Dongqing was an alternate sacrifice for Chiyou (the younger brother of Aga, the keeper of hades) after his childhood family was suddenly punished by heaven.

Xia Dongqing can communicate with the soul because of Chiyou, but Chiyou in his body has been sleeping. In Soul Crossing 2, when Xia Dongqing was protecting Zhao Li, his inner strength suddenly woke up and his eyes turned red, showing great strength. When Hades knew this, he felt that things were not simple, so he asked Zhao Li to follow Xia Dongqing to prevent this force from waking up again.
