Ye Qingxue is the human adopted daughter of Lu Chen, the Lord of Ghosts, who values her the least. Stirred up by her adopted sister Liu Hanyan, she has always mistakenly believed that her adoptive father would devour her, completely unaware that the one truly plotting to harm her is this seemingly gentle sister. At the brink of death after being secretly harmed by Liu Hanyan, Ye Qingxue awakens the Master of Cute Things System; touching a ghost allows her to cute-ify and subdue it, and also unlocks healing abilities. To rescue her adoptive father suffering from the Lunar Eclipse poison, the little toddler embarks on a perilous journey with a group of cute pets. Fierce beasts submit obediently in her arms, and powerful enemies turn into companions.
