Lãnh Phong found the laboratory three weeks after the funeral no one was allowed to hold.
It sat beneath a rehabilitation clinic outside the city, hidden behind permits, charity forms, and an old Union safety seal.
The sign aboveground promised recovery.
Physical therapy. Sports injuries. Back pain. Elder care. A place where families brought bodies they wanted healed.
That was how the lab had survived. Cruelty borrowed the shape of care, and people stopped looking.
Huyền Tinh Môn ran the methods.
The dirty Union faction provided silence.
Inside were cold rooms, metal beds, charts, pill batches, and names that had been reduced to reaction codes.
On one wall, someone had drawn a progress chart with neat colored magnets.
Red for failed.
Blue for stable.
Green for viable.
Lãnh Phong stared at the green magnets longest.
Not soldiers yet.
Ingredients.
Lãnh Phong entered through the loading bay during a storm. He did not announce himself. By then, grief had burned past noise.
The first guard fell without seeing his face.
The second saw enough to be afraid.
Fear made him honest.
"Archive level," the guard gasped when Lãnh Phong's hand closed on his collar. "The doctor is there."
Lãnh Phong did not know which doctor.
At that point, doctor still sounded like a word that belonged to saving.
The deeper Lãnh Phong went, the worse the building became. One room smelled of antiseptic. One of sweat. One of burned hair. A boy no older than Minh lay behind glass with his wrists strapped down, body shaking under a failed stabilizer reaction.
Lãnh Phong broke the door.
The boy inside was alive.
That made it worse.
Dead boys could be mourned. Living subjects had to keep proving they were not only evidence.
The alarm began.
Fire started somewhere above him. Later, people would argue whether he caused it, whether Huyền Tinh did, whether chemicals did what chemicals always do when men pretend control is permanent.
Lãnh Phong stopped arguing years ago.
He remembered heat.
Smoke.
Files scattering like frightened birds.
Names flashed under his feet.
Not all of them Vietnamese. Not all of them adults. Some were coded with initials. Some had school names in the margins. Some had family contact fields deliberately left blank.
Lãnh Phong understood then that Nghiêm Sư had not died for one laboratory.
He had died at the edge of a system.
Then a woman in a scorched lab coat kneeling in the archive room, coughing blood into her sleeve while pulling drives from a locked cabinet.
"Leave it," Lãnh Phong said.
She looked up through cracked glasses.
"If I leave it, they died for nothing."
"They died because of this."
"No." Her fingers tightened around the metal case. "They died because men like them always find desperate bodies and call them necessary."
The sentence cut through smoke better than coughing.
Lãnh Phong hated her for saying something true while clutching the thing that had helped make it true.
The ceiling split.
Lãnh Phong grabbed her wrist.
She fought him even while barely breathing.
"Let go."
"You first."
He dragged her through fire and falling plaster. Outside, rain struck the burning clinic and turned the night white with steam.
She tried to go back once.
Lãnh Phong caught her by the back of the scorched coat and pulled her down so hard her knees struck pavement.
"More drives," she choked.
"More death if you stand."
"You do not know what is inside."
"I know you are outside."
"Name," Lãnh Phong said.
The woman clutched the case to her chest like a child.
"Hạ Yên."
Then, after a silence that felt worse than screaming:
"I can fix it."
Lãnh Phong laughed.
Not because it was funny.
Because he had said the same thing over Nghiêm Sư's grave.
Hạ Yên heard the laugh and mistook it for contempt.
Maybe it was.
Maybe it was recognition arriving too early to be mercy.
Behind them, the clinic roof collapsed.
The sound swallowed every answer they might have given each other.
By morning, the news called it an electrical fire at a private rehabilitation clinic.
No one mentioned hidden beds.
No one mentioned reaction charts.
No one mentioned the boy Lãnh Phong carried out before he found Hạ Yên, because the boy's family signed a silence agreement before sunrise.
That was when Lãnh Phong learned the lab had not burned enough.
Hạ Yên remembered the fire by its alarms.
The facility used three tones: evacuation for staff, containment for subjects, and data purge for the server room. When smoke entered her laboratory, containment sounded first. The locked patients were considered a greater risk than the flames.
She opened two doors before the power failed. Behind the third, a teenage subject had stopped moving. Hạ Yên tried to lift him and discovered how little scientific authority weighed against a dead electronic lock.
Lãnh Phong arrived through the wall beside the door.
He did not ask who she was. He tore the hinges free, carried the boy to the corridor, and returned for Hạ Yên when she ran toward the server room instead of the exit.
"There are records," she shouted.
"There are people."
She hated him for making the difference simple. It was not simple to her. The records could prove what had been done and prevent repetition. They could also preserve the work that had enabled it.
Hạ Yên took one drive. Lãnh Phong carried her out while the rest burned.
By dawn, the official report described an electrical fire at a rehabilitation clinic. Families received silence agreements. Hạ Yên kept the drive and the guilt of every door she had not opened.
Lãnh Phong kept returning because he had seen which direction she ran when given one chance to escape.
In the present, Hạ Yên still carried the same drive in a case with a melted corner. When Minh once asked why she had not replaced it, she said the damage helped her identify the original.
She did not say that touching the warped plastic returned the weight of the third locked door to her hand.
