"How are we supposed to compete in this formation?" Yin Hua asked.

Zhouzhou replied, "It's simple. We'll each set up a formation and try to break the other's. Whoever does it faster wins. How about that?"

Yin Hua nodded. "We'll do it your way."

Zhouzhou shrugged and got to work.

Yin Hua glanced at it, his brows immediately furrowing. "Are you joking with me?"

The formation was made entirely of stones, and there weren't many of them at that. Was there even a need to break the formation? Not even an ant would be trapped by it.

The positive impression he'd had earlier from her drawing the symbols was now gone.

Yin Hua looked at Zhouzhou coldly, his face showing displeasure.
