The morning of the trial arrived cool and clear.
At the hollow's entrance, a weathered arch stood half-buried in moss. Three peaks had been carved into its crown. Between them hung the bronze outline of a bell, its surface worn smooth by time.
The candidates gathered in pairs while deacons checked their jade tags. Elder Yun repeated the rules, then raised his hand. "Enter when your pair is called. Keep your tags visible. The formations will shift after the last team crosses the threshold."
Lin Chen and Su Qingyao stepped beneath the arch together.
The first stretch of trail was easy. Pines crowded the slopes, their branches whispering above a narrow stream. Soon the path divided into three, each branch marked by a stone pillar. One was carved with a mountain peak, another with a flame, the last with a curling frost pattern.
Su Qingyao crouched beside the nearest pillar. "The map shows a single trail here."
"It may have changed." Lin Chen studied the ground. The left path bore fresh footprints, but the impressions ended abruptly in a patch of undisturbed moss. "Or the hollow wants us to choose quickly."
He closed his eyes and listened. The stream ran downhill to their right. A bird called from somewhere beyond the center path. The left branch held no sound at all.
"Center," he said. "The air is moving through it."
They followed the middle path. A few minutes later, a thin bell note drifted through the trees. It came from behind them.
Su Qingyao looked back. "Another pair?"
"Maybe."
A boy's voice followed, strained and distant. "Help! We can't find the trail!"
Lin Chen started toward the sound. Su Qingyao caught his sleeve—not to stop him, only to make him look at her. They exchanged a glance and moved together.
They found two younger candidates standing in a shallow basin. One had twisted an ankle; the other held a cracked jade tag in both hands. Around them, identical pines repeated in every direction.
"It's an echo formation," Su Qingyao said. "The voices are being carried in circles."
Lin Chen knelt and touched the soil. The earth was damp near the basin's edge. He followed the moisture to a small, clear spring hidden beneath the roots of a fallen tree. "The water flows outward. Follow it uphill, and you'll reach the main trail."
The injured boy looked relieved. "You'll lose time helping us."
"We've already found the way," Lin Chen said. "Come on."
They guided the pair back to the trail and gave them a spare bandage. By the time they returned to the split, the sun had climbed above the trees.
The injured boy tried to stand on his own and nearly fell again. Su Qingyao caught him beneath the arm while Lin Chen checked the jade tag for cracks. The tag's outer ring had split, but its inner core still held a little light.
"It can get you back to the entrance," Lin Chen said. "Break it if the formation changes again."
"What about your token?"
"We'll find another route."
The boy started to protest. Su Qingyao shook her head gently. "The hollow has more than one path. Don't spend your strength worrying about ours."
They watched the pair follow the spring uphill until the trees hid them. Only then did Lin Chen turn toward the center path again. He had given up time, but the decision had clarified something: the trial was not a race unless they chose to make it one.
The trial was designed to test them, not punish kindness. Lin Chen knew that. Still, he wondered whether the hollow had placed the pair there for a reason.
At the next ridge, the path narrowed between two rock walls. A line of tiny black marks ran along the stone, almost invisible beneath the moss. Su Qingyao's expression tightened.
"The same shape," she said.
Lin Chen reached toward it, then stopped himself. The air smelled faintly of ash.
Before he could answer, the mountain gave a low shudder. Far ahead, a bronze bell rang once.
The sound rolled through the hollow and stirred the mist.
