Lãnh Phong finally named them on a night without rain.
"Huyền Tinh Môn."
Minh repeated the words quietly.
Huyền Tinh.
"Sounds like a movie sect."
"Good," Lãnh Phong said. "Public disbelief is the oldest wall Võ Lâm ever built."
They sat in the empty gym with the lights off. Only the street glow cut across the mats.
Lãnh Phong had turned off every camera in Dạ Nam and made Minh place his phone inside a metal drawer. The ordinary precautions felt dramatic until Minh remembered the needle in the roof post and the broken cameras at the futsal court.
"Ordinary people think khí is cinema," Lãnh Phong continued. "Scam masters, flying monks, old stories. That helps real practitioners survive."
"And Huyền Tinh?"
"An old poison-observation line. Cold flow. Nerve disruption. Pattern reading. Spatial misdirection dressed as coincidence."
"So not one style," Minh said.
"No. A school of methods. That is worse."
Lãnh Phong's tone closed the door on simple answers.
Minh listened carefully.
Lãnh Phong lifted one finger.
"Sao Độc. Star venom. Usually mild at first. Numbness, fever, dizziness, rage spikes."
Another finger.
"Dòng Lạnh. Cold line. Stiffens motion. Interrupts breath."
Third.
"Mũi Lặng. Silent points. Hidden needles, pressure taps, small things witnesses explain away."
Fourth.
"Bản Đồ Sao. Their real cruelty. They chart you. Breath, shoulders, old injuries, emotional anchors. They make you feel like fate when it is only careful observation."
Minh thought of Hạ Yên's file. Primary emotional stabilizer. External martial pressure. Star contact. The words were different, but the shape was too close.
"Hạ Yên charts too."
"Yes."
"Then why is she different?"
Lãnh Phong's eyes stayed on him. "Because she wants proof. Huyền Tinh wants ownership."
The answer did not make Hạ Yên clean. It made the dirt easier to sort.
Minh thought of the video.
His steps turned into evidence.
"They sold cheap pills."
"To desperate boys."
"For money?"
"Money. Data. Recruitment. Control." Lãnh Phong's voice stayed flat. "The pills were never meant to create masters. They were nets."
"Could one work?"
"Enough to make the victim advertise it before the debt arrives."
That was the ugliest business model Minh had ever heard.
Minh remembered Lao's smile.
If power is real, you take it.
"Most people caught in nets die," Minh said.
Lãnh Phong looked at him.
"Yes."
The word sat between them.
Tùng.
Long.
The unnamed boy from Lao's group at the disused campus gym.
"Why me?" Minh asked.
"Because you did not die."
That was not comfort.
It was diagnosis.
Lãnh Phong stood.
"Lao wanted to make you honest. Huyền Tinh wants to make you readable."
"And you?"
Lãnh Phong looked amused. "I want to see what happens when the page refuses the pen."
Minh closed his hand.
"And if they can?"
Lãnh Phong's smile did not reach his eyes.
"Then someone will eventually try to own the chart."
Hạ Yên showed Minh how the cheap pills were sold without ever naming Võ Lâm.
Three screenshots filled her tablet. The first called them recovery supplements for amateur fighters. The second promised concentration during examinations. The third used no health claim at all, only a photograph of a thin boy beside his heavier future self. Different markets, same batch number hidden in the corner.
"Why would a môn sell through school accounts?" Minh asked.
"Because schools gather hunger in one place. Strength. Grades. Beauty. Belonging. You only need a different label."
She opened a complaint thread. Students described fever, tremors, sleeplessness, and sudden aggression. Most replies mocked them for taking an unknown product. Shame performed quality control for the seller by keeping damaged customers quiet.
Minh recognized one account from the restroom incident. The profile had vanished, but Mai An had saved the original post before deletion. Its attached photograph showed a packet reflected in a bathroom mirror. A partial distributor code survived backward in the glass.
Hạ Yên wrote the code on her glove. "This belongs to an old rehabilitation supplier."
"Yours?"
She removed the glove and placed it in a sample bag instead of answering.
At closing time, a courier delivered a box the clinic had not ordered. Inside were vitamin bottles with intact seals and no pills. Beneath the tray lay a printed copy of Minh's pulse chart.
No threat accompanied it. Huyền Tinh did not need one. The empty bottles said they controlled the product. The chart said they knew who had survived it.
Hạ Yên turned the box over to look for fibers while Minh checked the corridor. Neither touched the chart again. Their caution was already another result someone could measure.
Hạ Yên traced the empty bottles to a licensed supplement warehouse.
The warehouse had passed every inspection. Its purchase records showed vitamins, protein powder, and legal recovery products. The prohibited compound never entered the front inventory.
Behind the loading area, a worker showed them where identical bottle caps arrived in unmarked sacks. He spoke because his younger brother had taken one of the pills and spent two nights with a fever. He refused photographs and asked that his name stay out of every report.
Hạ Yên accepted the boundary. She took cap samples, delivery times, and the plate pattern the worker remembered. Minh remained outside so the presence of an injured schoolboy could not turn the man into a visible ally.
As they left, an inspector arrived early. The worker's face changed. Hạ Yên placed the sample bag inside her shoe and returned to ask about ordinary protein invoices while the inspector watched.
The exchange revealed Huyền Tinh's advantage. It did not need to corrupt an entire industry. It needed one invisible production step, one exhausted worker, one inspector willing to examine only the registered shelves.
Back at the clinic, Hạ Yên removed the flattened samples. One cap carried a star so shallow it appeared only beneath side light. The organization had marked even the part meant for the trash.
The worker sent no further messages. Two days later, the warehouse roster showed he had transferred shifts. Hạ Yên did not know whether that meant safety, punishment, or a choice to disappear from their investigation. She kept his name out of the file as promised.
