Xiao Yi's heart let out a cry of alarm.
In fact, he could not accurately determine the extent of the strength emanating from the Jade Pendant.
But he was certain that the aura was very strong.
Among all the strong presences he had sensed, not even the Divine Martial King nor the Abyss Demon Emperor, who had experienced a sudden increase in power, could match it.
Thus, he was sure that this was an aura surpassing the Heavenly Extreme Realm.
The purpose of the Jade Pendant was to sense the condition of the wearer of the other Jade Pendant at any time.
Judging from the strength of the aura, one could determine the present condition of the wearer, whether they were safe and sound or had been injured.
If there was no aura at all, it meant that the wearer of the other Jade Pendant had already died.
At this moment, the Jade Pendant in front of him radiated a stable and surging aura, astonishingly so; this meant that the wearer of the other piece was safe and sound.
