Some idea

Vincent set up some formations. He used flowers as his points. The flowers were placed in different places and seemed like they were random but when he was done, he closed his eyes and stretched his palm upwards. From his right palm, a magic rose and each of the flowers drowned in it one by one.

Finally, when all the flowers were doused in magic, he stopped. Then he made a summoning motion.

A geometrical pattern rose and Rose saw the red-orange color swirling in the pattern. This was a formation.

He then rotated it. The flowers remained stationary but the magic swirled and the faster it became, the beauty and the power increased.

Then he stopped. The pattern slowed and finally, it stopped at the exact position as it started. It fell back and disappeared.

"There, no spell can spy on you."

Rose was shaken. She had never seen anyone who practiced formations. It was just so beautiful and deadly.

"Thank you, Vincent."
