747 We Are Here

It was a pearl that was round and smaller than an egg. It didn't look like anything special, so most people would probably mistake it as a pearl for playing with. 

"It's one of the three royal treasures of Green Gallop Country, The Black Hurricane Spirit Pearl!"

The Headmaster was surprised that Nie Teng carried a treasure like this on him. It was extremely precious because it was made out of black obsidian and engraved with defensive array symbols. Just the defence array alone could withstand twenty attacks from Nascent Soul cultivators. In addition to its defensive power, it could also control the wind in the air. If a cultivator with wind properties were to get its hand on it, the pearl would play a great role in battle.

Nie Teng threw the pearl in the air, the pearl swept up the surrounding air to one side and sucked up the powerful airflow that formed a barrier into a whirlwind under the pearl, then sent that to the other side of the forest.
