Everyone in the arena saw the usage of Space Essence clear as day. Ning had used it twice in a row, once to send the crystals back at his opponent, and next to teleport right next him.
Each time, a small portal had opened in front of him through which he could go in and come out on another portal that had appeared close by.
At most, Ning could only use this technique at a 100-meter distance. Thankfully, that was plenty for a battle such as this.
He walked away amongst the cheers, a little sad in fact which he didn't show on his face.
He had his sword in his hand, but the sheathe was no longer anywhere. In the midst of chaos, one of the Crystal shards had hit his Wind sword, and given how little air was used to make it, it was completely destroyed with that one hit.
Now, Ning had no sheathe for his sword and would have to find another one, which most likely wouldn't be until after the competition was over.
