The richest man started taking advantage of loopholes after joining Alibaba.

Lin Che opened the second folder.

Historical prediction records.

The twenty-three articles, arranged chronologically, range from the earliest in February 2020 to the most recent in November 2022.

Each entry follows the same format: the left side shows the prediction result and date output by Abyss, and the right side shows the corresponding actual event and publication date.

He didn't start with the first point.

He started with Article 6.

Article 3 is from March 2021.

The left side reads: Abyss predicts that South American soybean futures will see a daily increase of more than 3% within the next two weeks, output date March 1st.

The right side reads: On March 12, South American soybean futures rose 3.7% in a single day due to expectations of reduced production from heavy rains in Brazil.

Lin Che pointed to the right side of the sixth line with his finger.

Then his finger moved to the checklist of the person in charge of national security on the table.

The first row of that table.

"Your records show that I established a position on March 8th."

The head of the national security agency nodded slightly.

Abyss's predicted date is March 1st.

"My entry date was March 8th."

"The public information was released on March 12th."

Three dates.

3月1日，3月8日，3月12日。

Lin Che read the three dates aloud, speaking very slowly, with a one-second interval between each date.

Let these three numbers go around in room 607.

Then it stopped.

"The timeline is in reverse order."

His voice was calm, but his words carried great weight.

"If I learned this through insider information, my source should have been at the same time as or even earlier than the time the publicly released information was published."

"But Abyss's predicted date was before I established my position, before the information was made public."

"It wasn't that I saw any inside information before making any moves; the system first built a model, and I made trading decisions based on the system's output."

The national security official lifted his finger from the table and picked up the pen.

It's black, the kind that matches the folder.

He paused next to the first row of the comparison table.

During the first three meetings, he drew question marks next to the forms.

It was drawn with a pencil, very lightly, but Lin Che could see it every time.

This time he didn't draw a question mark.

He drew a horizontal line.

It's short, about one centimeter long, drawn with a ballpoint pen, and heavier than a pencil.

It's not deletion, it's not negation, it's marking.

A horizontal line indicates that the nature of this row has changed.

The status changed from "pending verification" to "alternative explanations available".

Lin Che saw this action.

He didn't say anything, but his fingers twitched slightly under the table.

He continued flipping through the folders.

Article 7, July 2021.

Abyss predicts a portfolio rebalancing window for the rare earth sector, with the output date being July 7th.

Lin Che's portfolio adjustment date was July 15th.

Public information as of January 19.

Eight days earlier than expected.

Article 1, January 2022.

Abyss predicts the timing of dollar exchange rate hedging, with an output date of December 28th.

Lin Che established his position on January 4th.

Public information as of January 15.

Abyss acted a week earlier than Lin Che himself.

For each item read aloud, the person in charge of national security would draw a horizontal line on the comparison table.

Short, one centimeter.

By the sixth item, six horizontal lines appeared next to the six rows of the comparison table.

Six identical horizontal lines are neatly arranged where the question mark once stood.

There are no more question marks.

"Now I can explain something that you've been unable to explain all this time."

Lin Che pulled a piece of paper from the first folder.

This paper is not a printout, but a high-resolution scan of a photograph.

The photo shows a whiteboard with handwritten numbers and arrows on it. The handwriting is messy, and some parts are circled with a red marker.

"These are the 'Prophet's Physical Traces' that you marked in CR-1247."

CR-1247.

This is the internal number assigned by the National Security Bureau to the Lin Che case.

Lin Che shouldn't know this number.

But he knew.

The head of the national security agency glanced at him.

I didn't ask him how he knew the number.

Perhaps this is no longer important.

"Handwritten content on the whiteboard, pencil writing on the back of the paper, and draft paper on the desk."

Lin Che said.

"I understand that you treat these as physical evidence of 'knowing in advance,' because they were indeed written in advance."

"But they are not 'records of inside information.'"

"These are manual records of Abyss's offline tests."

"After the system outputs the predictions, I manually add validation annotations."

"The whiteboard is for outlining the timeline, the back of the paper is for key data points, and the scratch paper is for cross-validation calculations."

He pointed to a line of small print in the lower right corner of the whiteboard photo.

"This is the test date: June 30, 2021."

"Nineteen days earlier than the publicly available information."

The head of national security held a pen, the tip hovering above the checklist.

But he didn't draw a horizontal line.

He put down his pen.

Something appeared on the screen of the man on the left.

He quickly typed a few keys, and the page scrolled several times.

Then he did something that was the first time he had done since entering 607.

He turned the screen to a different angle so that the person in charge of national security could see it.

The light from the screen shone on the thin metal-rimmed glasses of the national security official, causing them to reflect slightly.

Lin Che could not see what was displayed on the screen.

But he could see the expression on the face of the person in charge of national security.

There were no major changes, but his brows relaxed a little, very slightly.

The national security official looked at it for about three seconds.

Then he nodded.

It was a very small movement, almost imperceptible.

But the man on the left saw it and turned the screen back.

He picked up the pen again.

In the bottom right corner of the comparison table, in the blank space, two words were written.

Lin Che couldn't make out what was written.

The woman on the right stopped typing.

She looked up and glanced at the pen in the hand of the national security official.

Then I glanced at the screen of the man on my left.

Her lips twitched, not in a smile, but as she bit the inside of her lip.

The chain of evidence has not disappeared.

It's still Article 21, the original SEC document or the blue stamp.

But the direction they were pointing to had changed.

From "conviction" to "evidence".

The same set of evidence and data, but with a different interpretive framework.

"You obtained inside information in advance" has been changed to "You have an AI system that can predict in advance".

The focus shifted from crime to ability.

Lin Che closed the folder and placed it on the desktop.

There are a lot of things on the table now.

The timeline table for Beijing Guoan has six horizontal lines.

Original document from the SEC investigation, with a blue stamp.

Lin Che's two folders contain edit logs and historical prediction records.

The screenshot from January 3, 2020 is still there.

The whiteboard photo is also there.

All the papers were spread out on the oval table, taking up most of the tabletop.

He didn't look at the expressions of the three people opposite him.

He is waiting.

We're not waiting for what they say, we're waiting for what they do.
