As a master of metaphysics hidden in the city, Lu Xingran has an unknown secret - his spiritual power depends entirely on his pet to survive. I wanted to keep a low profile and wait for death, but I didn't expect that one day when I went out to buy milk tea, I accidentally bumped into a girl with a "koi constitution" but was always entangled in supernatural events. The girl was soft-spoken and liked to hold on when things got tough, which made Lu Xingran's heart itch. From then on, the painting style of the metaphysic master suddenly changed: while others relied on spells to ward off evil spirits, he relied on passing hot drinks to girls; while others relied on magic weapons to fight against evil spirits, he relied on protecting girls from falling in love. "Boss, this ghost is a bit fierce!" The girl hid behind him and shivered. Lu Xingran crushed the resentful spirit with one hand and gently touched his head: "Don't be afraid, it's not as sweet as you." From the weird elevator in the office building, to the weird shikigami in the community, to the millennium obsession of the Internet celebrity attraction, Lu Xingran took the girl all the way to slay demons and sprinkle candies like crazy. Originally, she just wanted to prolong her life, but she ended up pampering her so much that she became the girl's exclusive patron saint. This is a funny story about a metaphysics master who, in order to survive, accidentally took sweet pets as his main job and demon-killing as his side job. The whole process is sweet and cruel, and the laughs are as good as dog food.
