Wu Mingyang innocently rubbed his head and said, "I dare not conceal it from the senior; this is something I accidentally stumbled upon."
Lin Feng thought for a moment, took out a space rule crystal from his storage bag, and handed it directly to the other person.
"We agreed to the trade; consider this book as bought by me."
Wu Mingyang was stunned, holding the space rule crystal the size of an adult's head, with an incredulous expression on his face.
"This… this is…"
"A divine-level Chaos core, kid, you've hit the jackpot!" Little Black said, his eyes gleaming.
He couldn't understand why Lin Feng was being so reasonable. After all, this kid was in their hands now; shouldn't he be at their mercy?
Why use a space rule crystal to trade? Won't that be a huge loss?
When Wu Mingyang heard this, he was immediately excited.
A divine-level Chaos core, isn't that a rule crystal?
