4. The Summit of Bones

The oasis of Turgen was not a place so much as a wound in the desert, a shallow depression where underground water seeped to the surface and coaxed a thin stand of poplars from the sand. For centuries, travelers had stopped here to rest their animals and refill their skins. A single way station stood at the edge of the trees, its walls built from the same yellow earth as the surrounding waste, its roof a patchwork of reeds and cracked tiles. Smoke rose from a chimney, thin and white against the pale morning sky.

Xu Xu reined in his horse at the crest of a low dune and studied the scene below. The way station was quiet. Two camels were tethered near the entrance, their loads still strapped, suggesting that whoever had arrived had not yet unpacked for a long stay. One of them was a tall Bactrian with a distinctive white blaze on its forehead—the same camel Zhang Liang had described seeing at the western gate of the Arsenal.

Fan was here.

Xu Xu dismounted and led his horse down the dune on foot, keeping low, using the sparse vegetation as cover. His body ached from the hard ride, and his bound wrists were bleeding again where the rope had shifted during the night. He had stopped only once, to saw the bonds against a sharp edge of rock until they frayed and snapped. His hands were free now, but the skin was torn, and every movement sent a dull throb up his arms.

He reached the edge of the poplar grove and tied his horse to a low branch. The way station’s door was closed, but the shutters on the single window were open, and he could hear voices inside. One was deep and rough, the voice of a man accustomed to haggling over prices. The other was softer, more measured. A servant, perhaps, or a junior partner.

Xu Xu crept closer, pressing himself against the mud-brick wall beside the window. The words became clearer.

“…told him the records were too dangerous to carry this far,” the rough voice was saying. “If a patrol stops me and searches the saddlebags, I am a dead man. The Assistant promised safe passage, but I have seen no soldiers, no escort. Where is the protection he swore?”

“The Assistant keeps his promises,” the softer voice replied. “You will be paid. But the records must reach Dunhuang. The buyer there will pay triple what we agreed if the seals are intact and the accounts are complete.”

“Triple? Why would anyone pay triple for a stack of old tallies?”

“Because those tallies show more than grain and arrows. They show where the Arsenal’s supplies really went. Names. Dates. Quantities. If the buyer knows what to look for, he can trace every transaction, every theft, every secret the frontier has buried. That knowledge is worth more than gold.”

Xu Xu’s blood went cold. This was not about a single debt or a single dead clerk. This was about an entire network of corruption, stretching from Juyan to the trade routes that led west. Qing had not just falsified records to cover a shortfall; he had been systematically extracting supplies from the Arsenal’s stores and selling them on the black market. The ledgers Fan was carrying contained the evidence—not only of Qing’s crimes, but of everyone involved. The buyer in Dunhuang wanted those records for leverage, or for blackmail, or for some purpose Xu Xu could not yet fathom.

He needed those ledgers. But how to take them? Fan was a trader, likely armed, and his companion was an unknown quantity. If Xu Xu burst through the door, he might kill them both, or they might kill him. And if the ledgers were destroyed in the struggle, he would have nothing.

He decided to wait. Patience was a soldier’s oldest weapon.

For two hours, Xu Xu crouched in the shade of the poplars, watching the way station. The sun climbed higher, and the heat grew oppressive, even in the thin shade. Insects buzzed in the dry grass. His horse dozed, its tail flicking lazily. Inside the building, the voices fell silent. Then the door opened, and Fan emerged.

He was a heavy man, broad-shouldered and thick-necked, with a beard that had been trimmed in the style of the western trade cities. His robes were travel-stained but finely made, the cloth dyed a deep blue that marked him as a man of some means. He carried a waterskin and walked toward the small spring that bubbled at the center of the oasis. His companion, a younger man with the nervous look of a perpetual subordinate, remained inside.

Xu Xu moved. He circled through the trees, staying out of sight, until he reached the spring. Fan was kneeling by the water, his back turned, filling the skin with slow, deliberate movements. Xu Xu stepped out of the brush and pressed the tip of his dagger against the trader’s spine. He had taken the knife from the Arsenal’s stables before fleeing, a short, curved blade used for cutting rope. It was not a soldier’s weapon, but it was sharp enough.

“Do not turn around,” Xu Xu said quietly. “Do not shout. If your companion comes out, you will both die here.”

Fan froze. The waterskin slipped from his fingers and floated downstream, bobbing in the current. “Who are you? What do you want?”

“I want the ledgers. The Arsenal records you took from Assistant Qing. Give them to me, and you may live.”

The trader’s shoulders trembled, but when he spoke, his voice was surprisingly steady. “You are the soldier. The one they are calling a murderer. Xu Xu.”

“I am.”

“Then you are a fool. Those ledgers are the only thing keeping you alive. As long as Qing does not know where they are, he cannot destroy them. But if you take them, he will hunt you to the ends of the Empire.”

“Let him hunt.” Xu Xu pressed the blade harder. “The ledgers. Now.”

Fan let out a long, slow breath. “They are inside, in a leather case under the cot. My servant will not resist. He is not a fighter.”

They walked back to the way station together, Xu Xu keeping the dagger hidden in the folds of his sleeve. Fan’s servant looked up sharply when they entered, but a single glance from his master silenced him. The leather case was where Fan had said it would be. Xu Xu pulled it out and opened it, his hands shaking despite himself.

Inside were dozens of bamboo slips, bound with silk cords, their surfaces covered in dense columns of characters. Xu Xu scanned them quickly. They were Arsenal records, just as Fan had said—inventories, receipts, disbursement tallies. But there were gaps. Numbers that did not add up. Entries that had been scratched out and rewritten. And names, dozens of names, including his own.

One slip caught his eye. It was a receipt, stamped with Wei Shi’s seal, recording a payment of two hundred coins from Xu Xu, Suizhang of Jiaqu Company. The date matched his memory. The seal was authentic. Here, in his hands, was the proof that he had been telling the truth.

Qing had not destroyed this receipt. He had given it to Fan, along with the other incriminating records, to be sold to the highest bidder. The Assistant was not just corrupt; he was arrogant. He believed the records would vanish into the western trade routes, beyond the reach of any imperial investigator. He had not counted on Xu Xu being alive to find them.

“These are what I need,” Xu Xu said, tucking the case under his arm. “But there is more I require. A horse. Supplies. And information. Who is the buyer in Dunhuang? What does he want with these records?”

Fan hesitated. The servant whimpered in the corner. Outside, the wind picked up, rattling the shutters.

“The buyer is a merchant named Su He,” Fan said finally. “He is not just a merchant. He is a former official, dismissed from the Imperial Treasury years ago for some offense he never speaks of. He has been buying records from frontier garrisons for years—tallies, ledgers, correspondence. He knows more about the Empire’s supply lines than the generals do. What he wants with these particular records, I do not know. I am only a courier.”

“A courier who asks no questions.”

“A courier who stays alive.”

Xu Xu took the trader’s horse, a sturdy dun mare with good wind. He left Fan and his servant bound but unharmed in the way station, with enough water to survive until the next traveler passed through. He did not relish leaving men tied in the desert, but he could not risk them raising an alarm before he was safely away.

As he mounted the mare and turned south toward Jiaqu Company, a thought struck him with the force of a physical blow. The buyer in Dunhuang. A former official of the Imperial Treasury, dismissed years ago. The description was vague, but the details gnawed at him. His father had served in the Imperial Treasury. His father had been dismissed in disgrace over a discrepancy in the grain accounts. Was it possible that Su He and his father had known each other? That the man who now sought to profit from the frontier’s corruption was somehow connected to the tragedy that had destroyed Qing’s family?

The coincidence was too large to ignore, but Xu Xu could not yet see the shape of it. All he knew was that the ledgers in his saddlebag contained secrets that reached far beyond Juyan, and that Qing’s scheme was part of something much larger—a web that stretched from the desert watchtowers to the corridors of power in the capital itself.

He rode hard through the afternoon, pushing the mare to her limit. The landscape shifted around him, the sand giving way to gravel plains, the gravel to cracked salt flats that reflected the sun like sheets of white fire. He passed a patrol of imperial cavalry, their red pennants snapping in the wind, and he pulled his scarf over his face and pretended to be a courier on official business. They let him pass without question. On the frontier, a man on horseback with a leather case was as common as dust.

By evening, he reached the outskirts of Jiaqu Company. The familiar beacon towers rose against the sunset, their fires just beginning to flicker in the gathering dark. He had not realized how much he missed this place until he saw it again—the rough stone walls, the smell of camel dung and cooking fires, the sound of soldiers laughing in the mess hall. This was his home. This was the life he had built over twelve years of service. And Qing had nearly taken it from him.

Chief Gao met him at the gate. The old officer’s face was grim, his eyes shadowed with worry, but when he saw Xu Xu dismount, he let out a breath that seemed to carry the weight of days.

“You are alive,” Gao said. “When Zhang Liang’s message reached me, I feared the worst. The Arsenal sent word this morning that you had escaped again. They are calling you a fugitive, a murderer twice over. Every patrol within fifty li is looking for you.”

“I am not a murderer. I have proof.” Xu Xu handed him the leather case. “These are the Arsenal’s records. Qing has been falsifying accounts and selling supplies on the black market. He killed Wei Shi to cover his tracks. And there is something else—a buyer in Dunhuang, a former Treasury official named Su He. These ledgers were meant for him.”

Gao opened the case and examined the slips, his weathered fingers moving carefully over the characters. His expression darkened with each passing moment.

“If this is true, it is bigger than the Arsenal. Bigger than Juyan. A former Treasury official buying military records—this could reach the highest levels of the Protectorate.” He looked up at Xu Xu. “You are still in danger. The Arsenal has issued a warrant for your arrest. If I harbor you, I am complicit in your escape.”

“Then do not harbor me. Send me to Dunhuang. Let me find Su He and discover what he knows. If there is a wider conspiracy, the Empire needs to know of it. And Qing needs to answer for what he has done.”

Gao was silent for a long moment. Outside, the beacon fires crackled, sending sparks spiraling into the dark sky.

“There is a supply caravan leaving for Dunhuang at dawn,” he said finally. “It is carrying dispatches to the Protector-General’s office. I can assign you as an escort. You will travel with official papers, under a false name. By the time the Arsenal realizes where you have gone, you will be beyond their reach.”

“And if the Protector-General does not believe me?”

“Then you will hang. But if what you have told me is true—if these ledgers are genuine—then the Protector-General will have no choice but to investigate. No one, not even a Commandant, can ignore evidence of systematic fraud against the imperial supply lines.”

Xu Xu spent the night in Gao’s quarters, too exhausted to sleep, too wired to rest. He spread the ledgers across the floor and studied them by lamplight, searching for patterns, connections, anything that might explain the scale of Qing’s operation. The discrepancies were vast. Grain shipments listed as delivered to beacon towers that had been abandoned for years. Weapons accounted for in the Arsenal’s books but never issued to the soldiers. Coins paid out for supplies that had never arrived. And running through all of it, like a dark thread, was the name of Assistant Qing.

But there was something else, something that did not fit. At the bottom of one tally slip, written in a hand that was not Qing’s, Xu Xu found a notation: *Delivered to Su He, per agreement. Quantity as specified. Seal of the Arsenal affixed.*

The slip was dated three years ago. Three years before Qing had arrived at Juyan. Three years before any of this had begun.

Whoever Su He was, his connection to the Arsenal predated Qing’s appointment. The conspiracy was older than the man who now sat in the Assistant’s chair. Qing was not the architect of this scheme; he was its inheritor, its latest custodian. And if that was true, then the roots of the corruption went deeper than Xu Xu had imagined, deeper than perhaps anyone in Juyan knew.

As dawn broke over the Gobi, Xu Xu mounted his horse and joined the caravan assembling at the southern gate. The air was cold and sharp, the sky a pale wash of blue and gold. Chief Gao stood at the gate and raised a hand in farewell, his face unreadable.

“Ride fast,” Gao said. “And do not trust anyone in Dunhuang. If Su He has been buying records for years, he will have allies. You will be walking into a city where every shadow may belong to him.”

Xu Xu nodded. He tucked the leather case securely into his saddlebag and spurred the mare forward. The caravan stretched out behind him, a line of camels and carts and weary soldiers, all bound for the distant oasis city where the trade routes converged.

Behind him, Juyan faded into the heat shimmer, its beacon towers shrinking to dark points against the endless yellow waste. Ahead, Dunhuang waited—a city of merchants and spies, of secrets bought and sold like silk. And somewhere in its labyrinth of streets and counting houses, Su He held the key to a mystery that had begun with a dead clerk and a missing receipt, and that now threatened to consume them all.

Xu Xu did not look back. The desert had taught him many things, but the most important was this: the past was a weight that could not be outrun. It followed you, silent and patient, until the moment you stopped to rest. Then it crushed you.

He would not rest. Not until he found the truth.
