Adrian used the Engraving Platform after reading the manual. He did not want to destroy such a priceless artifact that might fall in his hands. He also drew the magic circle with such detail that he did not know that time has passed greatly.
Gigan is also greatly impressed that Adrian has such concentration and did not bother him. When Adrian was finished with the first outer ring of the magic circle, he stopped and only to realize that four hours have passed. He did not expect such a time when doing something, but he has been told that he tends to lose himself in doing activities that require great concentration.
"I only finished the outer part and there are still three more. I already used up all my mana which is why I stopped." Adrian thought as he could see that the parts of the magic circle are indeed difficult to create.
