At that time, they were constrained by the script, and as soon as they discovered the stone slab, they were immediately captivated by its content, and didn't pay any more attention to what was inside the well.

"We've already got our Cards, what about you? Pei Junliang, aren't you going to go in and get your Cards first?" Qian Jiangyue asked, thinking from the perspective of Lan Jing.
