Hesi took a small, round box from his spatial treasure. The box was two inches high and about the size of half a palm.
"Master, this is a powerful defensive treasure I happened to come across long ago. Unfortunately, it is a treasure for human cultivators, so I cannot use it myself. I could never bring myself to sell it, so I have kept it with me all this time. Now, I present it to you, and I hope you like it."
Hesi held the box out to Lin Fei with both hands.
