This MC is so original

Legend has it that in the mountains and forests of Liyue, there is a cube fairy. As long as you offer him a green gem, he will give you what you want.
Whether it is building the Jade Pavilion for you overnight, or giving you a wooden shield that can block a blow from the Thunder God Wuxiang, or elytra that are more free than the Wings of Wind.
There are only things you can't think of, but there is nothing that the immortal can't do. As for where you can find him?
"Oh, my friend, I sincerely suggest that you should not go to that immortal if you have nothing to do. When the immortal is busy with his own affairs, he doesn't care about anything. For example, when he wanted to make a bed, he took a pair of scissors and cut Ganyu's clothes and hair. As for what do you want to know?"
Lu Xiu turned around and pointed at the three arrows behind him.
"The arrow she shot is still stuck in my back."
