Chapter 30 Counterattack (A must-read on 9k!)_2

"A trade? Is there any point in saying that now?" Old Du simply shook his head, slowly stepping forward with his hand resting on the handle of the knife at his waist.

"You need this." Yu Liang pulled out an object from his pocket, holding a key in his left hand and Old Jiang's longevity lock in his right hand. The tip of the key and the lock were almost touching each other. "That day during daylight, I found the sun model above the stage in the exhibition hall. I have always believed that the night exhibition truly exists, and the model in the night exhibition must be the moon. I have succeeded. I have synthesized the key which can open any lock, but it only works for the first time!"

"..." Old Du only stayed silent, his eyes wide open like bells, staring intensely at the key and lock in Yu Liang's hands.
