Zhang Yu was playing with the golden jade disc in his hand.
This magic artifact was about the size of a regular person's chest, looking like a flat circular jade piece with a hand-sized hole in the center.
The surface of the jade disc was covered with dense golden patterns, resembling complex mana circuits, enveloping the entire disc.
As Zhang Yu infused mana into it, the golden jade disc floated into the air.
At the same time, various parameters of the golden jade disc appeared in Zhang Yu's eyes, including mana capacity, power, and running time.
"Activate follow mode."
With Zhang Yu's soft command, pale lights appeared in the golden jade disc, locking onto Zhang Yu in front of it.
Then the jade disc slowly drifted behind him, hovering silently like a halo and moving with his posture.
Besides this follow mode, the golden jade disc also had attack, defense, and free modes, all equipped with basic intelligence, able to act according to the rules set by Zhang Yu.
