Grey did not bother with the Dragons and the Necromancers, sneaking after the Gnome who rushed into an underground staircase. With the help of his space element and excellent concealment ability, as well as a little bit of his array formations knowledge, he was able to sneak into the formation range without alerting anyone after creating some disturbances in other parts of the formation.
Sneaking behind the Necromancers, he rushed straight for the underground staircase. Following the staircase, he was led to a tunnel that led straight. He followed the path and arrived at the end of the tunnel. In front of him was an underground stream, and in front of it was the Gnome, making a series of hand seals.
Grey wanted to continue watching, but he suddenly felt a chill run down his spine, and without hesitation, he shot forward from where he was hiding, going into the open space in the underground stream.
