Well more than actually sensing Tianlong Yun's intentions that Planet Crystal fragment most probably sensed the high vitality contained in Tianlong Yun's body and jumped towards him.
After all, Tianlong Yun was a Great Ascension Boundary Realm cultivator with a life expectancy of more than a few hundred thousand years, while being just in his first century.
If he actually sat alongside other cultivators of the same Realm then his current body's age wouldn't be considered even as a spare change, but a simple 1 cent coin.
Of course, there should be a few more geniuses like him out there, who had the great backup of their Royal Clans, or their backgrounds in order to reach the same heights, but even they were counted on one hand's fingers.
Even though it would be a bit difficult to find some monstrous genius like Tianlong Yun even in the Immortal World.
