"Me?"
Eden seemed to have thought of her weight, and her face flushed slightly.
"No, no, no. I meant the syringe floating in your hand. Can you make it as heavy as iron?"
"I'll try..."
She did not quite understand what Liu Bai meant, but that did not stop Eden from trusting him. She focused all her thoughts on the syringe in her hand.
Besides, this was far easier to understand than the black hole Rita had mentioned—asking an art student to understand something like a black hole was simply unreasonable.
"Be more precise. Only apply it to the object."
"I... I'm trying."
Dense beads of sweat appeared on Eden's forehead.
Rita, standing nearby, watched the scene and silently reached out to touch it.
"That's enough, Miss Eden. Its weight is already comparable to gold of the same mass."
As Rita spoke, a look of realization appeared on her face.
She finally seemed to understand why Ei, Acheron, Chiyo, and the others considered Liu Bai a combat genius.
Liu Bai's method was indeed plain and unadorned... but extremely useful.
"...You make light things heavy, then smash people with them?"
Eden was quite perceptive and understood immediately.
"Yes, but probably not entirely the way you think. There's a number that's hard to avoid when calculating force. Eden, do you know what it is?"
"..."
You're making things difficult for an art student!
"...F?"
Eden answered cautiously.
Since it was force... she remembered F represented force, right?
"..."
An oddly awkward silence fell over the room. Only Illusion Moon, who could not care less, leisurely examined her nails.
"It's mass, M."
Rita did not know whether to laugh or cry. "In most formulas for calculating force, M is a necessary value."
"Isn't that still changing weight?"
Eden argued with a red face,
