Aimon was looking for the locked doors in Desire's Spiritual Vein and Core.
Even though the Spiritual Vein and Core were two different things, the locked doors were connected with them.
That was why Aimon was looking at both of them at the same time. Aimon was also using the 10 golden needles to act like a flashlight or something like that as he moved them in Desire's Core and Spiritual Vein.
'Hmm...Desire's Core is broken, but it's nothing serious.' Aimon thought as he looked at Desire's Core as he moved his hands.
Desire's Core was broken back when he was still in the Dungeon of the Spirt of Fire.
Well, Desire didn't know it, and that was why it didn't bug him that much.
Anyway, Aimon continued searching for the locked doors.
Looking for the locked doors was the hardest part of the technique, but opening them would be easy.
After all, that was the point of using something so precious such as Aurus Gold.
