The visitor came to Hạ Yên's office at 6:40 p.m.
That was ten minutes after most staff left and twenty minutes before the hallway lights switched to their cheaper night setting.
Hạ Yên noticed the timing before she noticed the woman.
People who arrived exactly between witnesses and darkness rarely did so by accident.
No martial pressure.
No hidden killing intent.
Just a woman in a plain blouse, government shoes, and a file folder tied with green string.
She looked like someone who could wait three hours at a ministry counter without losing patience, then ruin a man's life with one correctly stamped page.
That made her more dangerous than Huyền Kha.
"Thanh Lạp Ty," the woman said, placing a card on the desk.
青笠司.
Green Hat Bureau.
Hạ Yên did not touch it.
Cards were invitations. Invitations became records. Records became proof that a conversation had happened even when both sides later pretended it had not.
"I thought your office preferred daylight."
"We prefer useful timing."
The woman opened the folder.
Inside were photographs from the burned lab, Huyền Tinh pill samples, partial Union seals, and a blurred image of Minh leaving Dạ Nam.
The photographs were arranged with bureaucratic cruelty.
First the lab.
Then the pills.
Then Minh.
Past crime, current method, living leverage.
Hạ Yên's expression did not change.
"You have been busy."
"So have you."
Thanh Lạp Ty was not a method-gate, philosophical martial school, sworn brotherhood, or belief-based order. It was a government-linked bureau built to watch the things ordinary law could not name: illegal supplement rings, martial school licensing, dangerous khí incidents, heritage associations that were not only heritage.
In public documents, it handled cultural safety, traditional medicine fraud, and unlicensed combat associations.
In the files nobody requested twice, it tracked the hidden martial community the way flood agencies tracked river levels: quietly, constantly, and with maps nobody wanted to admit existed.
Public service in daylight.
Võ Lâm management in shadow.
"Your stabilizer research can become regulated," the woman said. "Protected. Useful."
"Owned."
"Protected things have custodians."
"That is a bureaucrat's sentence."
"It is also survival."
"For whom?"
The woman did not blink.
"For whoever signs early enough."
Hạ Yên almost laughed.
Almost.
Hạ Yên looked at Minh's blurred face.
"And him?"
"A survivor. A witness. A national-risk subject. Choose the term that helps you sleep."
"His name is Minh."
"Names can be included in formal files."
"That is not what I meant."
"It rarely is."
For the first time, Hạ Yên smiled.
It had no warmth.
"You offer protection because you want first rights."
"We offer legitimacy because guilt is private. Usefulness can be public."
That sentence entered too cleanly.
Hạ Yên hated that.
The woman had not accused her.
Accusation would have been easier. Hạ Yên had defenses for accusation. Shame, anger, technical correction, silence. This was worse. This was someone placing a ladder against the wall of her guilt and asking whether she wanted to climb out under supervision.
The woman stood.
"Finish the safer stabilizer. Report all changes. In return, no Võ Lâm faction touches you without touching the state."
When she left, the card remained on the desk.
So did the blurred image of Minh.
The woman had left it half outside the folder, either by mistake or by skill good enough to resemble one.
Hạ Yên opened Dataset 06.
For ten minutes, she typed nothing.
Then:
Objective: identity-stable amplification without ownership response.
Below it, she added a second line.
Purpose: unresolved testimony.
She did not sign the card.
She also did not throw it away.
At 7:18 p.m., the hallway lights dimmed.
Hạ Yên sat in the blue-white office glow and understood that protection had arrived wearing ownership's cleanest shirt.
She opened a drawer and took out the old metal case key.
It was useless now. The drives had been copied, hidden, split, encrypted, and moved across places even Lãnh Phong did not know. Still, the key had weight. It reminded her that the first evidence she saved had once fit into something small enough to hold against her chest.
Thanh Lạp Ty was offering a larger case.
That did not make it freedom.
On the desk, Minh's blurred photograph caught the edge of the lamp.
For a moment, Hạ Yên imagined writing one sentence beneath it:
Not yours.
She did not.
Not because it was untrue.
Because she no longer knew who the sentence would be addressed to.
The Thanh Lạp representative never offered innocence.
She met Hạ Yên in a government office annex where every chair was bolted to the floor. Her proposal contained protection, laboratory access, and legal custody for the safer pill. In return, Thanh Lạp Ty would receive verification rights and the authority to decide which faction could purchase treatment.
"You would control scarcity," Hạ Yên said.
"Someone will. We prefer records to auctions."
The answer described a real public benefit and a real concentration of power. Hạ Yên read the clause allowing emergency secrecy. It could hide her from Huyền Tinh. It could also hide a future failure from everyone else.
She amended the agreement by hand: three independent copies of adverse-event data, one outside Võ Lâm custody. The representative did not refuse. She circled the sentence and wrote subject to review.
Lãnh Phong waited across the street beside his motorbike. He did not enter the building because an older Thanh Lạp operation had once trained him in weapons, used his speed, and classified the cost afterward. Their help always arrived with a file number.
Hạ Yên returned carrying no signed protection, only the marked draft.
"You said they would help," he said.
"They will. The argument is over who gets to call it help."
She kept the paper. Refusing the first offer was the smallest proof that guilt had not taken all of her judgment.
The representative kept Hạ Yên's handwritten amendment after the meeting. In the margin she added a note for internal review: Subject requests protection from protector.
The sentence could be read as distrust. It could also become the first clause capable of restraining Thanh Lạp Ty later.
