Traveling to Modern Times and Picking up a Kitten Demon

You Xia felt that she was just an ordinary high school student - her grades were in the middle of the pack and she was good at playing games. Apart from her increasingly serious sleepwalking disorder, her biggest worry was that there was another demon subduing master with a bad temper living in her body. He called him Ruyi. Ruyi is very strong and can take over his body in the middle of the night to kill monsters; Ruyi is also very cold and disappears without a word every time he finishes his work, without even saying "Thank you for your hard work." Youxia felt that this was probably the most outrageous setting in his life - until he picked up a girl covered in injuries in an alley. "I came from the country... And got lost." The girl said. She called him Youxia and said that his food was delicious, that he would be scared to death when he saw a microwave, and that his eyes would light up like stars when he ate instant noodles. Youxia's nose has been able to smell evil spirits since she was a child, and he knows who she is. But he didn't expose it. Because she didn't hurt anyone. Because he was with her, he found that he was no longer alone. The threads of fate intertwined again hundreds of years later. The temperature of a bowl of instant noodles, the weight of a jade pendant, and the prayer "May there be a touch of green under your sleeves" - there is never a smooth road between humans and monsters, but they decided to walk together.
