Yan arrived at the practice alcove before dawn with the Ashen Marrow sequence memorized. The sky beyond the high windows had not turned blue. Gu set a small stone weight on the floor and checked the count against the corrected copy.
“Three measured breaths,” Gu said. “Not three full turns.”
“Three measured breaths.”
“Where does the force release?”
“At the shoulder, away from the spine.”
“And if you lose the count?”
“I stop.”
Gu looked at him for a moment, then placed the manual in the locked cabinet. “Good. You don’t need the book in your hands to practice the motion.”
Yan stepped onto the clean section of the alcove floor. He performed the hand motions slowly, keeping his arms loose. At the final turn, he stopped before gathering qi. He could explain the art perfectly, but the System had not activated it simply because he had read and memorized the manual.
Gu gestured toward the stone weight. “Describe the strike.”
“The force travels through the marrow, gathers behind the fist, then releases through the target.”
“Where is your weight?”
“On my back foot.”
“Then you’ll drive the force upward.” Gu moved the stone weight a little farther from the wall. “Reset.”
Yan widened his stance and turned his hip until his shoulder aligned with the weight. “Here?”
“Closer. Don’t reach with your arm.”
Yan shortened the distance and tried again. His fist stopped a handspan from the stone. “If I move the target farther away, I’ll overextend.”
“What can you change?”
“My feet.”
He shifted the front foot. The line from hip to shoulder straightened. This was ordinary training: no qi, no new strength, only a small adjustment that made the planned strike more precise. Yan enjoyed the satisfaction of getting the line right.
Gu shifted the weight again, angling it slightly toward the wall. Yan had to reset his stance rather than repeat the same motion. He planted his rear heel, moved the front toe, and let his hip lead. This time his shoulder lined up with the point where the stone met the floor.
“Would you strike the weight or the brace?” Gu asked.
“The stone. The brace would move if I hit it.”
“And if the weight slides?”
“I stop. I don’t chase it with my arm.”
Gu touched one edge of the stone. It shifted on the bare floor, rolling a few inches toward the wall. Yan began to follow it with his shoulder, then stopped and drew his arm back to his chest. The movement was small, but he felt how easily a planned strike could become a reach.
“I would reset,” Yan said. “I wouldn’t finish the motion at a new angle.”
“Good. Once the force starts, the target is not a reason to change the route.” Gu moved the stone back to its mark. “We’ll wedge it before the trial. You will not adjust mid-circulation.”
Yan stepped back and recited the sequence from the start without moving his hands. At the final breath, he traced the release with one finger. “That line ends here.”
Gu watched him. “And if you forget?”
“I stop before gathering.”
“I can call the count. You have to release when you hear it.”
“I will.”
Gu nodded. “That is a plan.”
He tapped the red warning written on the paper beside the weight. “Are you afraid of this?”
Yan considered the question. “I believe the manual.”
“That is not the same as being afraid.”
“It can ruin an ordinary body. But its force might let me earn a place beyond Ashfall.”
“You believe your body is different?”
“I don’t know what it is. The draught tests changed my circulation. That doesn’t mean I can ignore every warning.”
Gu held his gaze. “The method’s intended force may break the stone. The marrow strain can still harm you. If the sequence goes wrong, I will stop you when I can. I can’t promise to reverse a failure.”
Yan nodded. “Stop me if I lose the breath pattern, not when the expected internal backlash begins.”
Gu’s hand trembled as he reached for the paper. He steadied it against the table. “I can watch the sequence and the target. You remain responsible for choosing to continue.”
“I understand.”
“Say what you understand.”
“That the corrected sequence lowers the risk from a missing mark. It doesn’t make the technique harmless. A small charge and a stone target give us a controlled first trial, not certainty.”
Gu folded the paper. “Good.”
Yan performed the motion again without qi. His arm moved along the planned route, but his foot slid across dust at the edge of the alcove. He bumped the wooden target with his forearm. It clattered sideways, the sound loud in the empty room.
Gu laughed. “The marrow remains untouched.”
Yan caught the target before it fell. “I thought I had swept this side.”
“You swept the center.”
“The floor has expanded overnight.”
“Then sweep the new part.”
Yan reset the target and fetched a broom from the corner. He swept the alcove carefully, pulling dust from the seam where the stone floor met the wall. Gu helped move the weight onto a clean patch. They tested it with a light push; it slid, so Yan set a folded mat beneath it.
“Will that affect the strike?” Yan asked.
“It will show us whether the force lands where you aim. The mat keeps the weight from cracking the floor. It won’t change the warning.”
Yan checked that the target sat level. “At the next dawn?”
“At the next dawn. I want to read the final line again before then.”
They placed the chalk, mat, and weight beside the cabinet. Gu locked the Ashen Marrow text away. Yan’s muscles were warm from stance work, but his bones were unchanged. No power had entered him. He had not activated the method.
“Are we finished?” Yan asked.
“You are finished for today.”
“I know the sequence.”
“Then you can remember it until tomorrow.”
Yan picked up the broom. He swept the alcove’s dusty edge one more time, faster than Gu expected. The elder raised an eyebrow.
“I don’t want the floor expanding again,” Yan said.
Gu laughed and put the key in his sleeve. “Come back at dawn. We’ll see whether you remember that when the weight is in front of you.”
Yan left eager, but not magically stronger. Preparation had made the technique complete enough for a real trial, and the difference between knowing its steps and activating them remained clear. He had a target, a charge limit, a release mark, and a teacher ready to call a stop if he lost the count. At the next dawn, he would decide whether to begin.
