He hasn't given up.
"It's just some work-related issues. Not everything in the Metropolis can be solved with brute force. I told you not to meddle, so don't meddle. What, doesn't my sister-in-law's words carry weight anymore?"
Niu Ma widened her eyes.
"Of course not, a sister-in-law is like a mother. How could your words not carry weight? Well, I'm leaving now, sister-in-law."
Given the relationship between them, Liu Zheng couldn't press too hard.
"You can go. Oh, take this with you."
Niu Ma rummaged through the coffee table and handed him a paper package.
"This is a plaster given to me by a student's parent, originally meant for your elder brother, but he's often not home, so it's better not to give it to him. You can take it and use it."
She said.
"Then I won't be polite."
Liu Zheng accepted it directly, and the item description popped up immediately.
"Name: Dog Shit Plaster (Single-use)"
"Type: Tool"
"Quality: Excellent"
