Let's say Gu Yuan is here.

Gu Yuan calmed the Jianghu with his own strength.

He also took a break.

Huang group has nothing to catch for the time being.

So Gu Yuan asked Mo Wu to take charge of Huang group temporarily, while he was busy with other things.

Guyuan didn't go home, but went to Feiniao Internet cafe.

Coming to the second floor of the flying bird Internet cafe, fan Laixi's room was still so muddy that it smelled bad.

"Ouch, you finally came."

Gu Yuan wondered, "how did you know I would come to you?"

"Because you are curious about what the black curtain is."

Indeed, Gu Yuan came to find fan Laixi to clarify the black curtain.

Gu Yuan had heard of the black curtain before when he was in the East, but he only heard about it and didn't know much about it.

When Meng Qing died before, he said that his backstage seemed like a black curtain.

It seems that rose has heard before that the backstage of the underground bank is also a black curtain.

In order to make this clear, Gu Yuan can only ask fan Laixi.

"Then you know I'm here to ask this?"

"Of course I know."

Fan Laixi smiled.

"As the most secretive organization in the world, the black curtain claims to control the underground world."

"So, does this organization exist?"

"To be honest, no matter which intelligence agency, they all want to determine whether the black curtain exists or not. They seem to exist, but they don't seem to exist."

Gu Yuan covered his nose. "Don't talk in a roundabout way. Give me accurate information quickly."

"Exists."

In this way, Gu Yuan solved a mystery in his heart.

Intelligence agencies in many countries in the world want to determine whether the black curtain exists or not.

But no one has evidence to prove it.

Now, through fan Laixi's words, Gu Yuan knows that this organization is definitely not a legend, but a real one.

He knew that fan Laixi was not a person who spoke casually.

Once this guy can say it, he is 100% sure.

"Where is this organization hidden?"

"How do I know?"

"And what you don't know about Sixi tea house?"

"Brother, it's very good to find out the existence of the black curtain. Do you know how difficult it is for this mysterious organization to find out?"

"OK, tell me how you are sure."

Fan Laixi had a short rest with milk tea.

Then he said, "we found that the bosses of the killer alliance, underground banks, youth gangs and treasure houses would write a letter at the same time every year, so it was determined."

"A letter? Is it that simple?"

"Of course, it's that simple."

"Tell me."

Next, fan Laixi briefly described the process.

It turned out that situ Jing, the God of wealth, the landlord and Meng Qing would write a chicken feather letter every July 15.

This is quite strange. It is already the 21st century. Why do you write chicken feather letters?

And there is no connection between these organizations. Why do they write chicken feather letters?

Fan Laixi said.

"These feather letters were taken away by special carrier pigeons after they were written, and have disappeared since then."

"So?"

"So, this is very strange."

"Huh?"

"After our investigation, we found that those chicken feather letters were not chicken feathers, but crow feathers."

"Crow feathers?"

The more I heard it, the more strange it became.

Gu Yuan really didn't expect this to happen.

But what can even crow feathers prove?

"According to our information over the years, we found that a hundred years ago, there was a legend that the black curtain would be marked with crows when doing things."

This is probably the essence of the problem.

In those days, the black curtain was marked with crows, but now these people still use crow feathers when writing letters.

If it's just a coincidence, it's too coincidental.

What's more, they don't belong to each other, so it's strange to have common habits.

"July 15 of the lunar calendar, ghost festival, right?"

"That's right."

"In other words, the black curtain usually doesn't care about them, but these organizations can't become so powerful without the support of the black curtain."

"That's right!"

Now, the situation is becoming clearer and clearer.

Although those organizations still exist except that the killer alliance was destroyed, because their boss was killed by Gu Yuan, they are only semi disabled.

"Although all this is speculation, how can I make the black curtain surface?"

"This is more difficult."

"Oh? Is it that hard?"

"Because now my clue chain has broken, I can't continue to check."

"Your Sixi teahouse won't be so incompetent."

"No, but the organization to be investigated next is not very easy."

"Not very easy?"

"Yes, they are Jeff Institute."

"Jeff Institute, what organization is this?"

"In name, it is a medical institution, but in fact, the evil organization specializing in human organ trafficking is based in the West."

"Organ trafficking? Are they all doctors?"

"Yes, they are all evil doctors. The knife you caught, special Liu, was one of them."

Gu Yuan had just read the briefing before. It was because of organ trafficking that Dao teliu became a dangerous person. Unexpectedly, he turned out to be a member of Jeff Institute.

"It is said that Dao teliu saw that organ trafficking was profitable, so he ran back to work alone, and then became a dangerous person."

"So what is the connection between the Jeff Institute and the black curtain?"

"Director Jeff will also write a letter on July 15 of the lunar calendar every year, and will also affix crow feathers."

This behavior is similar to other bosses.

Fan Laixi continued: "this is the only person known to be alive who will have such an action. If he is also dead, the clue will really be broken."

Gu Yuan understood what Fan Laixi wanted to say.

Is to ask Gu Yuan not to kill Jeff.

However, Gu Yuan and Jeff have no grievances. How can they kill each other.

"So, the clue of the black curtain depends on this person to solve it, doesn't it?"

"In the current situation, yes."

Fan Laixi didn't hide it. Anyway, Gu Yuan would tell him what he wanted to know. Basically, there was no such big problem.

"According to this situation, I'm afraid we won't be able to find a good clue for a while."

"Yes, after all, it is difficult to find the trouble of Jeff Institute. They are more secretive than other organizations."

"In that case, let's walk step by step."

Fan Laixi seems to have remembered something.

He immediately said, "team leader Gu, you should be careful."

"Be careful what?"

"No matter your Jianghu identity or any other identity, someone is coveting it."
