"When the Great Prince killed Hu Ma, do you know how they invented the bronze wire with thorns they pulled?"
"Hmm? Isn't that iron?"
"The difference isn't that big. Do you know how?"

It was with great difficulty that the speaker voluntarily brought this up, so the girl of the other party naturally felt a thread of joy. She sincerely said, "I don't know."
"Oh, copper wire is difficult to pull out," the gentle voice sighed and said. "I heard it was the Jiangnan merchants fighting for a piece of copper board and pulled it out through with sheer force."
This joke was originally rather amusing. Coming from his mouth, it seemed rather cold.
The corners of the girl's mouth only twitched.
