30: Chapter 30 Extortion by the Police

Very quickly, Lin Heng obtained that confession.

To be honest, with the information contained in it, even Sherlock Holmes would probably shake his head.

The person simply confessed that he was working for a superior and didn't even know what he was doing. He was only told by his superior that the contents of the USB drive were extremely valuable, and he was even threatened using his superior's parents and children.

Other than that, there were a few frequently visited addresses of the Murderer, as well as some testimony from the suspect's contacts.

However, all of it was about irrelevant matters.

For them, it offered no help in solving the case.

This...

Everyone present started to feel embarrassed.

"Damn it, if this case can be solved, I'll take your surname!"

"Exactly, isn't this purely making things difficult? With this time, we might as well look for other people possibly related to the Murderer."

"I personally feel a bit of a headache."

"No wonder they asked Lin Heng to come. They truly have no clue about this matter."

"..."

Everyone shook their heads one after another.

They started to feel a bit sorry for Lin Heng.

That twenty thousand yuan was about to fly away!

For a money-grubber like Lin Heng, wouldn't he go crazy?

Su Xueer cleverly took a shot of Lin Heng, but at that moment, everyone realized they had misjudged him!

Lin Heng showed no signs of panic; he even appeared remarkably calm.

It looked as if he was completely certain of solving this case.

Then, Lin Heng's lips curved slightly.

He was familiar with this kind of thing!

Billions—he had encountered this when he was trying to crack Bitcoin before.

Such a huge sum of money couldn't possibly vanish into thin air. Setting aside offline transactions, those billions probably wouldn't even fit into a single bank vault, let alone be handled by an ordinary person.

It must have been transferred via online banking, but this has one characteristic!

That is, there will definitely be bank records.

Furthermore, although Bitcoin is decentralized, when facing a true master, being traced is not impossible.

"Isn't this simple?"

Lin Heng smiled slightly.

"We just need to find those in the country who have large-scale digital currency transactions based on the amount. We'll find it with one check. Maybe we can even uncover other individuals or companies engaging in illegal operations."

"Based on my observation of the crypto circle, it's probably around Inner Mongolia, perhaps the North? I suggest thoroughly investigating those few northern provinces."

As soon as he said this, everyone was stunned.

Although that was what he said, how could they so easily find those numerous digital currency traders in Dragon Country?

"It seems Lin Heng doesn't know everything. Such a massive amount, and it requires bank cooperation—the workload isn't just a little big."

"Moreover, Lin Heng immediately named a location. Isn't that just talking nonsense?"

"Exactly. Everyone knows Bitcoin is completely decentralized. How could it be found? Even the person who created Bitcoin would never have imagined a successor saying something like this."

"Just look at the expressions of the police officers present; Lin Heng is probably going to stumble this time."

"..."

The crowd buzzed with discussion.

Lin Heng had indeed stumbled this time.

His display of prowess fell short.

At that moment, the few Special Case Unit police officers present also managed a wry smile.

"Although Lin Heng has had a few impressive performances before, I think this matter is still too difficult for a University Student."

"Chief, why don't we just drop it? I don't think Lin Heng grasps the depth of this issue. Should we study it ourselves again?"

Someone quickly suggested letting Lin Heng leave.

For a moment, everyone looked toward the Chief.

But at this time, the Chief shook his head with a bitter smile.

Just when everyone thought Lin Heng was about to be kicked out, they saw the Chief suddenly speak:

"To be frank, what Lin Heng said is correct. There is one more element I failed to disclose to everyone, and that element is exactly what Lin Heng mentioned."

"I thought it wasn't very important, as it only narrowed down the scope and didn't significantly impact the case."

This statement shocked the entire room.

What the heck!?

Lin Heng actually guessed it right!!

The audience in the livestream room were momentarily slow to react.

But soon, someone pouted.

"Tsk tsk, he probably just guessed!"

"I think so too. Electricity is cheap in Inner Mongolia, so many people mine Bitcoin there. The largest mining farm was developed there. Back when I bought a graphics card, it had a pungent smell, so I knew it had been overworked by a mine owner."

"Exactly. Everyone knows that area is the vanguard of mining. Contacting the northern provinces is within reason. Lin Heng was just lucky this time; there won't be such luck next time."

The crowd discussed animatedly.

They all believed Lin Heng had guessed it.

Many of the police officers present also smiled wryly, thinking Lin Heng had just gotten lucky by chance, merely making some correct guesses.

At this moment, Lin Heng curled his lip.

These people probably didn't know that the money he had been tracking before was actually the batch they were currently looking for.

If the other party hadn't gone offline in the end, perhaps those billions in Bitcoin would have ended up in his own pocket.

There would be no business for them.

Lin Heng was actually very clear about the addresses of those people.

He just hadn't expected to be asked about this aspect here.

Originally, Lin Heng had lost interest in this matter, but now that there was a legitimate opportunity to acquire money, how could Lin Heng miss it?

The main issue was that if that money came into his hands, it would be illicit funds, requiring laundering, which was troublesome.

After some thought, Lin Heng continued, "Although Bitcoin is decentralized, you cannot deny that the person who created it invented it to aggregate computing power from computers."

"As long as there is a source, no matter how many times it has been encrypted, the location can be found."

"After locking down those few locations, by continuing to investigate the loss of computing power, you can quickly find where the illegal transactions are occurring."

Upon hearing this, everyone scoffed even more.

"May I ask what 'loss of computing power' is?"

Someone quickly questioned him.

Lin Heng rolled his eyes at that person, "Isn't that simple? Check the electricity meters!"

At these words,

Everyone suddenly understood.

Holy cow!

It was this logic!

If, in an instant, a sudden increase and decrease in Bitcoin occurred in one location, it would cause a temporary voltage peak and trough in one of the locations.

By using tracking methods to investigate, they could get a general idea.

Since the approximate location had already been locked down, the next step was the process of elimination.
