Five hundred li is exactly two hundred and fifty kilometers.
For a cultivator at the Foundation Carving realm, the distance represents a brisk afternoon transit. For an outer disciple with a null root, zero internal qi circulation, and a body practically allergic to ambient spiritual energy, it is a three-day march through elevation changes that actively punish the lungs.
I relied on momentum. Momentum does not require cultivation. It only requires a refusal to stop walking.
The terrain of the Ashen Borderlands shifted on the second day. The loose, calcareous dust of the Desolate Peak Sect's valley floor gave way to jagged ascents. The air grew thinner. It smelled of dry pine and old iron.
I had planned the route meticulously. The location was not a guess.
On my second day in this body, I had noticed a faulty bronze latch on the door of the sect's administrative storage annex. The latch mechanism was worn down by decades of improper friction. A physical vulnerability. I filed the observation under potential utility. Two weeks later, I walked through that door and acquired a stack of discarded, mildewed geographical survey scrolls. They were poorly drawn. The topography was largely inaccurate.
But they marked a natural cave system in the Broken Spine Mountains.
The distance was calculated for exactly two logistical requirements. It was far enough that outer sect patrols would never wander there by accident. It was close enough that a round trip on foot could be achieved between the bi-weekly ration checks.
I reached the coordinates at mid-morning on the third day.
The rock of the Broken Spine Mountains was structurally incoherent. Limestone does not naturally fold into high-density crystalline veins without a heat event that would have leveled the continent. I ran my thumb over the seam where the two minerals met. The temperature differential was four degrees.
The entrance was a fissure. Barely wider than a man's shoulders.
I squeezed through. The air inside was completely still, carrying the heavy, blank scent of undisturbed stone. Not damp. Impossibly dry for a mountain range that caught the eastern monsoon rains.
I set my pack down. I had no qi to circulate. The original body's desperate attempts at cultivation had left the meridians exhausted, stripped bare by the effort of forcing a river through a sieve.
So I used a pickaxe.
Iron and wood. The rhythm of metal striking stone. It took four hours to widen the interior choke point and clear the debris from the primary chamber. Blisters formed on the webbing of my thumbs. They tore open on the rough wooden handle. My hands bled. I wrapped them in strips torn from the hem of my grey outer disciple robe. The fabric was already ruined.
By dusk, the chamber was cleared. Five meters across. A natural ventilation shaft angled upward toward the ridge, pulling a faint draft from the ceiling.
I washed the dust from the back wall using water from my canteen.
The water hit the stone and cleared a thick layer of grey silt. Beneath the dirt, the rock was not blank.
Deep grooves cut into the solid granite. I held my lantern closer. The cuts were mathematically precise, devoid of the micro-fractures that a chisel or blade leaves behind. Whatever carved them had displaced the stone without shattering it.
I counted them. Thirty-seven distinct characters.
They did not match the common script of the Myriad Fathom Realm. They did not match any linguistic root from Earth. The energy density residing in the shallow cuts was completely silent, yet it possessed a structural weight that made the air near the wall difficult to breathe.
Someone was here before me.
Whoever they were, they operated at a level of power that reduced solid granite to warm butter. And they had stopped carving mid-sentence. The thirty-seventh character ended in a trailing, unfinished line.
Why does someone with that much power stop mid-sentence?
I traced the final groove with my bandaged thumb. I had three hypotheses. All three were probably wrong in the same direction. I filed the characters under concerning but currently irrelevant. I was not here to solve historical mysteries. I was here to disappear.
I built a fire pit using river stones gathered from the lower slope. Ignited the kindling. Smoke rose, caught the draft of the natural shaft, and vented seamlessly outward.
Heat pushed the cold iron smell out of the center of the room. I sat on the ground.
The fire popped. A piece of damp sapwood splitting.
This was peace.
No assessment stones shattering on contact. No inner disciples making jokes about null roots. No political marriage contracts to an Empress I had never met. Just a man, an empty cave, and a plan that required absolutely nothing from anyone else.
I unpacked the seeds I had taken from the sect's compost heap.
The sect gardeners routinely threw away viable clippings if the leaves showed minor discoloration. It was a fundamental misunderstanding of root resilience. A dying leaf is a symptom, not a death sentence. I had dragged dark, heavy topsoil from the valley floor during my ascent. Three trips. I banked the soil against the southern wall, where the ambient temperature was stabilized by the fire's proximity.
I planted the clippings. Pressed the dirt down.
My hands were black with soil and dried blood. My shoulders ached in a dull, mechanical way. I stayed in the cave for three more days. Establishing the perimeter. Measuring the dimensions. Testing the water filtration from a small spring near the back of the chamber.
On the morning of the fourth day, I needed to return.
Bi-weekly rations. Outer disciples who miss the ration call are flagged for truancy. Truancy means administrative attention. Attention means visibility.
The walk back took seven hours. The downhill slope was easier on the lungs but brutal on the knees.
The Desolate Peak Sect looked exactly as it had when I left. Sweeping grey roofs. Imposing courtyards designed explicitly to make the people standing in them feel small.
I bypassed the main training grounds. I took the service path behind the alchemy pavilion, moving quietly through the afternoon shadows.
The sect's primary spirit herb garden bordered the path.
I kept walking.
Then I stopped.
I looked at the third bed from the left.
Silverthread root. An autumn-growth variety. The leaves on three of the plants were yellowing from the center vein outward, curling at the edges in a specific, crisp pattern.
The cultivator responsible for this bed had watered them perfectly. The spacing between the stalks was exact. They had done everything according to a manual written by someone who understood spiritual energy but did not understand dirt.
Autumn rain in this specific region carried high alkaline deposits from the eastern ash plains. Silverthread root requires a slightly acidic soil matrix to process ambient spiritual energy. If the soil pH rises too high, the root suffocates. It starves while sitting in water.
I looked at the path ahead. The ration hall was four hundred yards away.
I did not need to fix this. It was not my problem. It was the exact opposite of my problem.
I resumed walking. Three steps.
I stopped again.
A perfectly engineered biological system was dying of administrative incompetence.
I turned around.
I walked back to the third bed. I scanned the perimeter and found a dense deposit of pine needles and decaying mulch near the treeline. High acidity. I gathered two handfuls and worked the material into the topsoil around the base of the three yellowing plants. Not too deep. Just enough to alter the surface filtration when the next rain hit.
It took four minutes.
I brushed the dirt off my knees.
I walked away. I was profoundly irritated.
I had come here to be invisible. I had found a cave five hundred li away specifically to avoid interacting with this world. And I had just spent four minutes performing unauthorized agricultural maintenance on sect property.
It was a failure of discipline. I made a mental note not to do it again.
I was probably going to do it again.
