"I have a Spatial Top with me, which is able to gauge the stability of a space and determine one's level of control over a certain space. Whoever is able to keep this top spinning for the longest time possible will be deemed to have the deeper understanding of space!"
As Nangong Yuanfeng spoke, he flicked his finger, and a top of roughly a chi long appeared before everyone's sight. It stood motionlessly on the elevated platform, and even though there was no energy emanating from it, there were still many slight dimension rifts around it.
The presence of dimension rifts hinted that the space was not stable. In order to get the Spatial Top to stand, one had to reconstruct a stable space, or to put it in simpler terms, mend the dimension rifts around.
