Standing inside the eye of the heat storm, Lin Tao didn’t look at the roaring flames. He looked at the floating numbers in his eye.
Outside the four-foot null partition, the burning vault had reached eleven hundred and forty degrees. The star-iron floor plates had turned the color of ripe apricots, softening into a semi-liquid state that sagged under their own mass. The air was filled with a terrifying, nonstop sound scream of sixteen point four cycles per second. The hum of an uncontained fusion runaway.
Inside the cool square, Lin Tao’s right hand was trembling wildly against the steel land-mapper metal pen.
The skin of his palm was scorching, not from the external fire, but from the massive bio-electric back-EMF surging through the needle from the mountain’s decaying firmware.
The cold metal of the needle shook against the bone of his right index finger. It sent micro-tremors through the forearm nerve into his shoulder. The phantom feedback was not physical fire. It was the raw, unbuffered signaling of an ancient machine screaming under a load it had carried for three hundred years. His scarred right palm throbbed in harmony with the Precursor pulse, the old melted rock waste burns flaring red beneath the skin.
Through the current-carrying steel shaft, Lin Tao had established a direct hardware screen with the engine’s internal registers:
The ancient Precursor engineers who designed the Thermal Reclaimer Model 4-C had implemented a self-running load counter to measure cumulative heat breakdown. To prevent runaway reactions, the engine had been programmed to execute an emergency mass-venting subroutine whenever the load approached its capacity.
The counter was stored in a standard thirty-two-bit signed integer register.
For three hundred years, the ignorant overseers of the Azure Cloud Sect had operated the fire without ever clearing the memory registers. Every failed cooking pot, every barrel of sulfur coal. Every high-pressure smelting run had incremented the register. It climbed inexorably toward the theoretical limit of two billion, one hundred and forty-seven million, four hundred and eighty-three thousand, six hundred and forty-seven.
Now, with Meng’s three barrels of demon oil fueling the fire, the register was only thirty-five units away from saturation.
If the register soaked and rolled over into negative territory unguided, the engine’s magnetic holding arrays would experience an unhandled exception. The entire five-story stone ziggurat would implode, followed a split second later by a total repulsive blast that would level half the mountain.
Lin Tao raised his left thumb to his lips.
He took the blunt tail of his land-mapper metal pen, placed it against the thick callus of his thumb, and pressed downward with deliberate, measured force until the steel pierced the deep skin by a tiny fraction of an inch.
A clean, sharp spike of body pain shot through his nervous system. A bead of dark crimson blood welled around the steel.
[Branch checked: physical main]
The pain cleared the static from his visual cortex. His heartbeat steadied, dropping from one hundred and eighty-eight to one hundred and forty beats per minute. The body anchor re-established his baseline mental clarity, purging the phantom nerve echoes that threatened to dissolve his sanity.
He was awake. The freezing cold of the null square was real. The roaring inferno outside was real. The thirty-five units of margin were real.
“Tie Shan,” Lin Tao whispered through cracked, bleeding lips.
“Here,” the giant rumbled. He crouched low, his broad hands bracing Lin Tao’s shoulders to absorb the violent sound shakes that rattled through the stone floor plates.
Beside him, Tie Shan’s jaw was set like a granite block. Even with the searing heat howling outside their four-foot haven, the giant didn’t flinch. His dark eyes remained fixed on the glowing seams of the dark rock floor, ready to throw his body across Lin Tao if the ceiling collapsed. To Tie Shan, the young checker was no longer merely a fellow prisoner or a clever clerk. He was the master who held the reins of the mountain’s dying heart.
“When the number reaches the peak,” Lin Tao said, his voice flat and deadly calm, “the blast door will cease to exist. The blast wave will travel south to north. Keep your head between your knees and hold the foundation plates.”
Tie Shan didn’t ask questions. He locked his massive arms around Lin Tao’s waist, planting his Iron-Bone weight into the stone foundation like an unmoving anchor. He had seen Lin Tao predict the collapse of the melted rock waste mounds and the flow of molten copper with unnatural, infallible care. In the giant’s mind, Lin Tao was not guessing. He was commanding the mountain’s iron bones to obey an ancient decree.
Lin Tao turned his left eye toward the silver capacitive trace running along the star-iron baffle.
Thirty... Twenty... Ten.
The counter was climbing with terrifying speed:
2,147,483,638... 2,147,483,642... 2,147,483,645...
Lin Tao lined up the needle-sharp plumb point of his metal pen with the main grounding trace.
The silver filament was less than the width of a spider-silk thread, inlaid directly into the crystal-clear lattice of the star-iron plate. In a normal running environment, this trace carried microvolt feedback signals from the heat core to the Precursor governor array.
Now, it was shaking with a high-pitched, faster-than-sound shriek of twenty-four thousand cycles per second.
Lin Tao drew a slow, shallow breath, steadying his right wrist against the intense body tremor that ran from his fingertips to his collarbone.
“Two taps, Tie Shan,” Lin Tao whispered, his vision swimming in a sea of violet colorful aberration. “Hold the stone.”
Tie Shan tightened his grip around Lin Tao’s legs, burying his face into his knees. His Peak Iron-Bone thickness locked his entire balance point into the bedrock. The giant didn’t close his eyes. Through the gaps between his thick fingers, he watched the silver metal pen hover above the glowing star-iron plate.
In the corporate server rooms of Lin Tao’s former life, an engineer who met a runaway thread didn’t panic. He traced the stack, isolated the leaking pointer. Then he forced an interrupt to prevent data corruption.
Here, in this decaying world of stone, fire, and immortal arrogance, the principle was matching. The ancient Precursor engine was not a mystical fire. It was a heat-powered processor running on unmaintained firmware. Its integer register was thirty-two bits of signed memory waiting for the final overflow.
One.
Lin Tao’s metal pen touched the silver filament.
Ting.
The counter clicked: 2,147,483,646.
Two.
The final positive unit registered: 2,147,483,647.
The register was soaked to its theoretical maximum limit. Inside the crystal-clear core of the engine, the logic gate paused, awaiting the next order.
Zero units remained.
