Genshin Impact: Adopted by the Son of God at the Beginning

[Time travel, protagonist growth, slightly sweet, slightly knife-like, no system, no harem] Fourteen-year-old Lan Xingyi has always been curious about his life experience, but whenever he asked his sister Yae Shenzi, he would always be fooled by the pink-skinned fox. "You, it was a sweet flower I picked up on the roadside that turned into..." "Really? Sister, then why am I..." Why don't you have flowers on your head?" "Haha, I'm kidding you~ Silly boy, I'm going to the Yaedo Hall to read a story. Just stay in Narukami Grand Shrine and wait for my sister to come back. Don't make any trouble, otherwise..." "Huh, my sister is the worst, I'll never ignore you again!" At the same time, the people in heaven also watched this scene. "Forget it, what kind of waves can a little brat make?"
