Genshin Impact: as Keli's Younger Brother, I Became the Group's Favorite

Bai Jing traveled to the continent of Teyvat, and while awakening to the modern weapon system, he also turned into an eight-year-old kid. Not only was Keli taken in as her little brother, but he also gained the love of a bunch of older sisters. Qin: "Little brother, come sleep with your sister tonight." Lisa: "My little apprentice, you have endless tasks. Come and chat with your sister for a while~" Noelle: "You can't sleep by yourself. I'll stay with you, otherwise you'll be scared." Keli: "Good morning, little brother Bai, do you want to go out to play with Keli today?" Yola: "Humph, my chest was covered with drool when I was sleeping. I will bear this grudge!" Bai Jing, who had lived in Mondstadt for a short time, immediately became everyone's favorite, but gradually people became stupid. Why did he always feel that this **** eldest sister wanted to do something evil to him? I'm still just a child! Just when Bai Jing was feeling depressed, a sound came from the system again.
