He Easily Unlocked the Demon King's Seal, but She Refused to Leave.

I have been wandering for many years, and I have broken not one hundred but eighty seals. Only this time, what emerged from the sarcophagus was not a monster, but a sleepy beauty. She rubbed her peach blossom eyes and muttered: "Who are you... Disturbing someone's sleep..." I sheathed my sword and said, "Sorry, I'll put it back on you." "Wait a minute." She suddenly hooked my sword spike, "Little swordsman, your eyes are so beautiful." Later, I found out that the lazy beauty who was rescued was the world-destroying Demon Lord who was talked about in ancient times. ——Now she is twirling my ponytail with her fingertips: "Xi Yu, didn't you want to seal me again?" I looked at the sky: "How about I tie you up and throw you back now?" "Oh?" She smiled and bit open my hair rope, "Then use this to tie it up."
