"You have 20 minutes to replenish your Qi by sitting inside your Qi Gathering formation, and afterward, you'd have to replicate the formation you were stuck inside as precisely as you can."
Before speaking, Elder Zayd channeled his Qi into one of the formations already inscribed on the walls of the room. It isolated noise and made the other two participants unable to hear their conversation.
The test was supposed to have a surprising effect which would be lost if Ken's speed revealed the content to the other two. Zayd did not expect someone to finish the second part before the rest finished the first one; if the rest knew they'd have to use their Qi Gathering formation, they'd work harder on it, which Zayd did not want.
"How similar do I have to make it?" Ken asked curiously. He could replicate it to nearly 100% with his proficiency, but he believed nobody expected them to copy a whole formation to such a degree.
