Might makes Right (Part 1)

The metal angel was formidable enough to keep struggling even after being covered by that net. It was attempting to cut it open with the heavy sword in its hand. The net contracted in an instant, trapping the angel securely. The metal angel continued to wiggle about, shooting countless metal blades to cut the net.

Saleen did not bother with it and shot another lightning icicle at yet another metal angel. He then opened a sealing scroll and threw the metal angel in the net inside the scroll. That scroll's creation was entirely dependent on luck, as it was at level-11, the highest level of a scroll that both Saleen and his teacher were capable of creating.

As a level-10 mage, the creation of a level-11 scroll only had 20 percent of success even when starline paper was used. Every time Saleen ventured outside, he had to bring about 100 scrolls of such level.
