It stepped out of the wall-darkness and it was not a beast.
It was a construct. Stone and iron and something that moved between them — a figure the height of two men, shaped roughly human but not quite, with a surface that shifted between material and energy. It moved like intention made solid.
Ancient text carved into its chest read: REALM KEEPER. GUARDIAN OF THE REMAINING.
It looked at them. Or oriented toward them — it had no eyes in the human sense, just two recesses that emanated faint light.
Then it spoke. Old language. Wen Dao caught fragments. He had read the archaic script on the walls. The construct was saying something about a test.
'It wants to test us,' he said.
'Test us how?' Cai Rong said, his voice very controlled.
The construct raised one arm. In the floor, a stone disk rose — circular, with carved lines running in patterns. A platform.
'I think one person stands on it,' Wen Dao said.
'And does what?' Li Meng asked.
'Probably fights it.'
A long pause.
'I'll go,' Wen Dao said.
'You're at Level Five,' Cai Rong said. 'That thing is—'
'Suppressed. The realm's own laws suppress everything above Qi Condensation Level Four. This is ancient. It would have operated under those laws.' He wasn't certain. But the logic held.
He stepped onto the disk.
The construct moved immediately. No warning. It came in with both arms sweeping simultaneously — a crushing attack designed to overwhelm range.
Wen Dao dropped flat to the disk. Both arms swept over him.
He was up in an instant. He moved inside its reach. He hit the center of its chest — the carved text. Nothing. Like hitting stone.
Of course. It was stone.
He stepped back. He looked at it. It was made of something. That something had a structure. Joints. Connection points between sections.
Questions. Ask questions.
It swung again. He moved with it, watching the motion. The shoulder joint. Carved stone over stone — there was a groove. A gap. A weakness.
He hit the groove on the next swing. Hard. Pointed knuckles, concentrated force.
The swing deviated. Small deviation. But real.
He hit the same spot again. And again.
The construct moved differently after the third hit. Its pattern changed — it was adapting. Intelligent.
Wen Dao adapted faster.
He found three structural weaknesses over the next ten exchanges — the shoulder groove, a hip rotation joint, and a place on the lower neck where two stone sections connected imperfectly.
He cycled hits between all three. Never the same spot twice in a row. The construct kept adapting but each adaptation revealed a new stress point.
His arms were burning. Level Five body tempering was working hard against the construct's stone surface.
On the nineteenth exchange, the construct slowed. Just slightly. But noticeably.
On the twenty-second exchange, the chest carving glowed briefly.
On the twenty-fourth exchange, the construct stopped.
It lowered its arms.
It looked at Wen Dao with its eyeless recesses for a long moment.
Then it bowed. A simple, deep bow.
It moved back to the wall. The wall closed behind it.
The stone disk descended back into the floor.
Li Meng rushed to Wen Dao. 'Are you all right?'
'My arms hurt considerably,' Wen Dao said.
'You—' Cai Rong shook his head. 'You fought a stone construct to a standstill at Level Five.'
'I asked it questions with the technique until it ran out of answers,' Wen Dao said.
From the altar, the iron box had changed. A second compartment had appeared. Inside it: two pills. A note with them in archaic text. He read it slowly.
'One is a Qi Root Accelerator. It prepares the dantian for Qi Condensation crossing far ahead of time.' He picked up the second one. 'This one has no name written here. Just a symbol.'
The symbol was the same pale flame from Elder Shao's jade.
He pocketed both pills.
He looked at the technique cloth one more time before sealing it carefully in his inner robe pocket.
'We should leave,' he said. 'We have what we came for.'
They started back toward the entry point.
They had been inside for eight hours.
And somewhere behind them in the ruins, the sound of many running feet was growing louder.
