Hearing Zhang Tie's cough, Donder raised his head from behind the counter. However, he didn't show any surprise, just revealed his teeth.
"Brat, you've come back here. Do you want me to invite you for a lunch?"
"Yea!"
Zhang Tie revealed an innocent smile and honestly nodded.
"No way!"
Donder's face immediately looked as hard as the door plank of the grocery store.
"If so, I will go then. Previously I thought that if you invited me for a lunch, I'll give you something as a payment for your care for me in the past years..."
After saying that, Zhang Tie pretended to leave.
"Heh heh. You want to cheat me with this trick. Brat, don't forget that I taught it to you. I've already played and become tired of this trick dozens of years ago..."
Donder smirked behind the counter, seemingly having seen through Zhang Tie's lie.
