It was true that Ureyn was not ready for battle against Adam, he did not expect that he would have to leave his mill today and that it would be destroyed.
However, like any monster in the Forgotten Mills, he understood how the String Duel worked. If Phantom came to fight him, then he had to possess the same abilities, or very similar ones.
Up to that point, that was exactly how it had been.
Adam's threads, needles, and cut were a reflection of the main power of each of the three factions. As Ureyn showed, this was not something unique, because he, too, could use several powers at once — cut through his wind and needle with techniques. However, white threads were not available to him.
But his example also showed that combining several powers was ineffective. As soon as he fully accepted his wind and abandoned the techniques of the Gray Needle, he not only brought Draug's wrath upon himself, but also focused entirely on one path.
However, what did Ureyn see now?
Lightning.
