He looked at Kai.
Then frowned.
"The hell's wrong with you?"
Kai pointed toward the door.
"...You told me to knock."
"I did."
"...So I waited."
"...Why?"
Kai stared.
"...Because nobody answered?"
Dr. Z threw both hands into the air.
"The door was unlocked!"
"What were you doing?"
"Dawdling outside?"
Kai opened his mouth.
Closed it.
Opened it again.
"...Normal people don't just walk into mysterious buildings."
Dr. Z looked genuinely confused.
"...Why not?"
Kai decided not to answer.
It wasn't worth it.
Dr. Z shrugged.
"Aight."
"Sit."
He pointed toward a reinforced chair positioned beneath several mana lamps.
Kai walked over.
Sat down.
While waiting—
He quietly observed the room.
Every table had been organized.
Perfectly.
Every tool sat exactly parallel to the others.
Measurements written in chalk covered one wall.
Half-finished blueprints littered another.
Mechanical arms.
Mana tubing.
Tiny enchanted gears.
It looked chaotic...
Yet somehow every single object had its own exact place.
Dr. Z returned pushing a heavy metal table mounted on wheels.
It rolled silently across the floor.
He stopped beside Kai.
Then immediately began arranging instruments.
Magic scalpels.
Mechanical clamps.
Crystal needles.
Mana injectors.
Steel arms folded neatly against the side of the table.
He adjusted one scalpel.
