An Enemy That Cannot Be Seen

Han Sen and Gu Qingcheng frowned. The shadow Xie Qing King had drawn had possessed the power of a Viscount. It had been destroyed within one second, so whatever lurked inside the valley was scary.

"There is no need to rush. Watch this." Xie Qing King flipped open his book and drew something else with his fingertips.

Not long after, another leopard came leaping out of the pages. It didn't run straight into the valley, and instead came to heel and crouch near Xie Qing King.

Xie Qing King kept wagging his finger across the book, and after a few minutes, another four leopards joined the first. When done, he said, "Okay! This is the maximum I can do."

He commanded the five leopards to enter the mist of the valley, all in a horizontal line.

Each leopard ran forward at the same time, all together, but they kept a few yards of space between them. When they entered the valley, there was a movement from within the fog.
