Using his <Supreme Engineer> and <Supreme Architect>, a blueprint of the house that the Supreme Academy had given to Allen and Iris materialized in front of Allen. The combination of those two <Supreme > talents allowed Allen to possess the skill to create any blueprints of any buildings that he saw or within his surroundings.
After Allen caught the blueprint in his right hand, he opened the blueprint and inspected its contents.
"It's decent."
That was Allen's comment towards the house that was built using the <Supreme Engineer>'s blueprints.
Allen's <Supreme Engineer> talent far exceeded the <Supreme Engineer> and <Supreme Architect> combined. Allen's comment was already a compliment since if the <Supreme Engineer> and <Supreme Architect>'s works were that bad, Allen would have commented that it was bad.
