Bai Mengmeng

Bai Mengmeng is a major ally during Xie Yan's mission to Tong Ling. She is a silly plutomaniac, shamelessly trying to flirt with Xie Yan for his wealth.

Plot
Xie Yan transmigrates to the world of Tong Ling, where he is issued the mission to kill the Ghost King Lin Feng within six months, without leaving the city of Xia Shui. Through the ghost of Bian Gui, Lin Feng targets the descendants of his servants, including Xie Yan, but even after numerous attempts, he is unable to kill Xie Yan because of the latter's unusual prowess. Irritated with Lin Feng, Xie Yan hires the famed Feng Shui Grandmaster Sheng Gun and his disciple, Bai Mengmeng to exorcise the ghost. The duo try to dupe Xie Yan, but the ghost ambushes them. In the ensuing scuffle, Sheng Gun is killed by the ghost, while Xie Yan barely escapes. The ghost retreats and Xie Yan awakens Bai Mengmeng.

Bai Mengmeng warns Xie Yan that he has only six months left before death, because the Finger Of Nirvana is consuming his life force, and the only remedy is to manifest a guardian spirit to extend the lifespan by a few years. On Xie Yan's orders, Bai Mengmeng concocts the Progenitor of Mysterious Yin. Xie Yan bathes in the concoction and Bai Mengmeng helps him acquire the Transcendental Spirit Nurturing Technique. Xie Yan's guardian spirit transforms into an owl devoid of personality, because he used the system to hatch it instantly. Later, Xie Yan and Bai Mengmeng visit an abandoned, haunted house in Xia Shui that was built on the land rumoured to be the location of Lin Feng's original residence. There, the duo are attacked by five bewitching ghosts, but Xie Yan swiftly thwarts them. He questions the frightened ghosts about Lin Feng and learns of a nearby well haunted by Lin Feng's Ghost Generals. Xie Yan demonstrates his prowess against the Ghost Generals, and wins the affections of the bewitching ghosts who share their residence with him and Bai Mengmeng. Xie Yan spends the next few weeks exterminating the Ghost Generals. He grows closer with the youngest bewitching ghost, Cyany.

Later, Xie Yan begins to teach the Heavenly Guard to Bai Mengmeng. Two months later, she exchanges several copies of the incomplete Ultimate Demonic Bliss Technique for many shamanic techniques. She selects the four best techniques for Xie Yan who fuses them to create the Spirit Casting And Soul Consolidation Technique. Eventually, the fated night between Xie Yan and the revived Lin Feng arrives. Bai Mengmeng livestreams the event. After a difficult battle, Xie Yan reaches the 9th layer of the Acquired Realm and kills Lin Feng, three months before the mission deadline. Xie Yan attempts to send a message to Bai Mengmeng, but he and Cyany are abruptly transported to the Main World.
