During a Threesome, the Ghost Becomes Her Mentor?

Since being sent back to the underworld by Empress Houtu three thousand years ago, Yin Hetao has been adopted by Black and White Wuchang, and has become a "conscientious" good ghost! No one knows her true identity. Only her ability to burst out occasionally when she encounters danger makes her doubt that she is not a little ghost baby. However, she just wants to live a leisurely life and does not want to work hard to find the truth. However, it seems that the way of heaven does not always follow her wishes... Something seems to be wrong with this ghost collection operation. Yin Hetao is actually trapped by a resentful ghost. She can't get out of Renai Hospital. She uses special communication equipment from the underworld to finally connect to Black and White Wuchang who is on vacation, but the connection ends up getting disconnected! What a bad luck! How can she escape from the abandoned hospital? During the next mission to collect ghosts, a phoenix lotus fire rescued her from being trapped. She also accidentally met this 50,000-year-old little princess of the Phoenix tribe who had escaped from her engagement. After solving everything, she thought she could get rid of this annoying little girl. Unexpectedly, the subsequent ghost collecting incidents became more and more bizarre, and during this incident, he also met a little sharkman left over from ancient times. Gradually, the three of them became friends who always quarreled...
