Yu Xiaolian and Jiang Lin were giggling as they filled a basket with goji berries. On their way back, Jiang Lin suddenly asked, "What was that thing you had on your eye yesterday? Why did you put it on your eye, didn't it hurt?"
"That thing is called a beauty lens. It can change the size and color of the eyeball and adheres to the eye without hurting."
Jiang Lin added, "That's good. If it hurts, you shouldn't wear it."
Yu Xiaolian stopped in her tracks and looked at Jiang Lin seriously, "I suppose you've guessed where the antidote I used to save you came from yesterday. I'm a descendant of the Witch Clan. I hope you can keep this a secret for me. I don't want to be caught one day and bled dry."
Jiang Lin earnestly declared, "Who would dare? Whoever tries to bleed you, I'll kill them!"
Yu Xiaolian laughed, "Brother Lin, I don't have any siblings, and neither do you. How about we become sworn siblings? You can be my elder brother, alright?"
