Tân Phong found the disappearances inside attendance sheets.
Not hacked records. Not secret files. Photographs students posted when teachers left grade books open, screenshots from class groups asking whether transferred friends still owed money for uniforms, public competition lists with names that stopped appearing.
He arranged eleven students across a spreadsheet disguised as examination revision.
Seven had contact-sport histories.
Five had clinic visits after suspected supplement use.
Three appeared on old event lists tied to illegal supplement testing.
Every school used different language for their departure.
Medical transfer.
Family relocation.
Voluntary withdrawal.
Temporary remote learning.
The dates formed one clean sequence after Thanh Mạch assessments.
Thuận read the sheet during lunch while Khánh Vy revised literature two tables away. He kept the screen tilted from her, an ordinary act of secrecy performed so often it no longer felt active.
"We need addresses," Tân Thành said.
"We need consent," Thuận answered.
"They are missing."
"Some may have left safely."
Tân Phong tapped three rows. "These did not. Their accounts went silent within one day of transfer. One family moved without closing a rental contract. Another left a motorbike at school for two weeks."
"Then we check routes, not homes," Thuận said. "Bus cameras, public events, competition contacts. No knocking on frightened families' doors while someone watches who visits."
Tân Thành pushed the phone back. "By the time routes answer, Lao reaches them."
The missing kickboxer had become the argument inside every delay.
After class, Tân Phong visited the records office under the honest excuse of correcting his own emergency contact. The clerk made him wait beside shelves of paper folders while a printer produced transfer certificates.
He did not touch restricted files.
He watched labels emerge.
Three carried the same partner code printed on the Thanh Mạch notice.
One carried a destination:
`Youth Adaptation Center - temporary.`
No address.
The clerk placed the certificates in opaque envelopes.
"Where is the center?" Tân Phong asked.
"Which center?"
"The one on those transfers."
She looked down and covered the code with another folder. "Outside school responsibility."
The phrase told him more than an address would have.
At the old Vovinam floor, Hạo Nhiên examined the spreadsheet and forbade direct entry into any center they located.
"We do not know whether the students are held, treated or moved again," he said.
Tân Thành stood near the door. "We know they disappear."
"Knowing the harm does not automatically give us a safe method."
"Safe for who?"
Hạo Nhiên accepted the question.
Thuận gave Tân Phong one task: identify the transport company without following a vehicle.
Tân Phong heard the control inside the precision.
"You want the route without letting me use mine."
"I want you not to disappear with it."
"That is different from asking what risk I accept."
The room tightened.
Tân Thành looked between them and said nothing. His silence no longer meant agreement.
That night, Tân Phong traced the partner code through public procurement notices. The Youth Adaptation Center did not exist as a registered facility. Its transport contract belonged to a medical logistics company with a warehouse near the western edge of the city.
He did not send the address immediately.
For ten minutes, he held information nobody else possessed.
The feeling was not power.
It was space.
Then he remembered the middle-school boy behind the ropes and sent the location to both his brother and Thuận at the same time.
Not leader first.
Not brother first.
Equal information.
Thuận replied with instructions.
Tân Thành replied with one question:
`When do we look?`
Tân Phong answered his brother first.
The following week, one empty seat appeared in a Grade 12 classroom at Lê Quý Đôn.
The student was not a fighter. He had filmed part of the public assessment and uploaded a reflection showing the black camera module. His family told the school he was studying remotely while they handled a health matter.
Tân Phong checked the class chat. The student's account remained active but answered with formal phrases unlike his usual messages.
`Thank you for concern. I am safe. Please respect family privacy.`
The same sentence appeared in two missing students' chats from other schools.
It also appeared in the response guide distributed after Khoa's previous Trưng Vương event. Tân Phong still had an archived copy from that evidence route. The wording was not similar. It was identical, including the missing article before `concern`.
Below the old guide sat a red footer:
`Protect the person. Reduce the rumor. Restore trust.`
Hồng Y had turned crisis language into a reusable product. A family could type the sentence willingly and still be speaking through a script designed to end questions.
Tân Phong printed all three rather than saving only screenshots. Paper did not report who opened it.
He showed Thuận after training.
"Witnesses too," Thuận said.
"Not only fighters. Anyone who records the wrong equipment becomes part of the register."
Tân Thành wanted to visit the family.
This time Thuận did not answer first.
Tân Phong chose. "No home visit. We send one ordinary classmate with homework and ask whether he sees the student. No martial names."
The classmate returned with the homework still sealed. A man at the apartment door said the family had relocated for treatment.
"Clean shoes?" Tân Thành asked.
"Office shoes," the classmate said, confused.
It was the same detail a neighbor had used when describing the first disappearance. Nobody had taught either witness to notice it.
Tân Phong added a witness column to the spreadsheet.
The document stopped looking like disappearances after assessments.
It looked like a perimeter being cleared before something larger moved.
Tân Phong added another column.
`PUBLIC VERSION.`
Every disappearance now carried two routes: where the student might have gone and what everyone else had been trained to believe about the absence.
At home, he copied the file onto an encrypted card and hid it behind a loose electrical faceplate. His brother watched from the doorway.
"You have three copies," Tân Thành said.
"Four."
"You trust none of us?"
Tân Phong replaced the screw. "I trust you. I do not trust what people can make you reveal while believing you are protecting me."
Tân Thành wanted to argue.
The funeral ended the argument before it began.
Before sleeping, Tân Phong added three more rows beneath the missing students.
Thanh Thuận.
Tân Phong.
Tân Thành.
Not missing. Marked.
He filled the route column for each. Thuận: school, old floor, Khánh Vy. Tân Thành: school, home, training. His own route contained more blanks.
The blanks did not make him safer. They showed where fear had prevented him from building a life anyone could describe.
He encrypted that observation too, although no enemy would have found it useful yet.
Across the city, Khoa reviewed engagement reports from the three privacy messages.
He did not know the students' medical classifications. Hồng Y gave him numbers instead: concern declined after the second family statement; classmates stopped asking after the school repeated the privacy line; one witness's video lost circulation after comments accused him of exploiting a sick friend.
Khoa marked the template successful.
Then he opened Tân Phong's public profile and saw no posts at all.
Silence should have made a person difficult to measure. Tân Phong's silence felt deliberate enough to become its own shape.
Khoa created a separate file for him.
