Three Disciples

A tiny crack on the wall caught Fugaku's attention. If the Mangekyo Sharingan hadn't enhanced his vision, an ordinary Three-Tomoe Sharingan would have had a hard time spotting the difference.

He pressed both hands against the wall, continuously feeling and pressing around. A hidden compartment that fit this tightly against the wall required a specific mechanism to open; purely using hands would require destroying the wall just to take the hidden compartment out.

The outer layer of the wall was secured with heavy steel plates, looking smooth and cold. The position of his left hand suddenly sank into the wall, and the spot that originally bore a subtle crack popped open to reveal a compact hidden compartment.

Inside the hidden compartment sat a small, transparent glass jar filled with nutrient solution, roughly thirty centimeters high and ten centimeters in diameter. At the bottom of the jar rested a piece of substance five centimeters long, five wide, and three thick.

He unscrewed the lid and instantly sensed the potent vitality within it. He cut a small piece off the First-Generation Flesh and put it back into the jar.

Inside the jar was nutrient solution. Given the vitality of the First-Generation Cells, it wouldn't take long for it to divide back into the state it was in before being cut, leaving no one any the wiser.

He put the jar back, pushed the hidden compartment back into place, took out a scroll inscribed with a Sealing Formula, and sealed the cut piece of flesh into the scroll.

He arrived at the laboratory door once more. Through the crack, he could see the previously stationed ninja still standing guard. Black Mist surged beneath his feet, and the soles of his shoes stepped lightly on the ground, producing a faint sound.
