The recipient is the owner of a shop in Xicheng City.

In the letter, Japanese merchants proposed to purchase a batch of goods, so they agreed with the shop using the letter.

Such a letter looks very ordinary. If ordinary people see it, they won’t take it too seriously. Most of the time I have read it, it’s fine.

But it happened that the snake head of the Japanese camp was always responsible for resisting the Japanese guild hall, so I knew a little more than ordinary people.

Out of professional sensitivity, he soon realized something was wrong.

First of all, the Tokyo Guild Hall itself also has a room in the West City. If you want to buy goods, just come and interview directly. Wouldn't it be more convenient to negotiate a good business in person?

Secondly, the owner of the shop that Japanese merchants want to purchase has a very ordinary background.

Snake Head knew that the owner behind this shop was a famous figure in Chang'an.

Japanese businessmen actually went to this shop to do business by letter. No matter how they thought, they felt that there was something wrong with it.

So Snake Head reported the matter to the Japanese camp, and the news spread layer by layer, and finally came to Cui Liulang.

Cui Liulang attached great importance to this information when he received it. He immediately drew personnel and followed the line to investigate.

Unfortunately, after checking for several days, I found no useful clues.

The Japanese businessman from the Japanese Guild Hall did order a batch of goods from this shop in the West Market. Except for the strange thing about ordering with letters, no abnormalities were seen anywhere else.

Just when Cui Liulang was a little relaxed, Zhou Yang heard about this and quietly peeked at Cui Liulang's file. Then he was overjoyed and found the key to the case.

I have never found any useful things when I checked the Japanese Guild Hall before, because the Japanese knew that the Tang Dynasty was paying attention to them, so I acted very low-key and cautiously.

So does the order letter contain code words? Or are there any other clues?

Zhou Yang believes it is very possible.

He proposed a hypothesis.

If the Japanese Seizakuo of the Tokyo Guild knew that the people of the Tang Dynasty were monitoring them, what would they do?

Of course, I try every means to hide it in a low-key manner.

People from Japan are staring at people entering and leaving, which is easy to be exposed. It is very likely that they can collect information and communicate information through the secret line of letters.

Zhou Yang did not believe that there was something in this world that was not for no reason.

If something goes wrong, there must be a reason.

After he made a judgment, he did two things. First, he carefully analyzed the content of the letter to see if there were any secret words like hidden ones.

Second, send someone to focus on the store in the West City to find new clues.

Zhou Yang's actions were soon noticed by Cui Liulang.

Then the case became a person from both sides, each investigating and forming an independent team.

It is not common to communicate information, just like hostile competition.

However, in private, because the files are all in the Japanese camp, people on both sides often peek at each other's file information.

The problem now is that Zhou Yang found that there were indeed information such as hints and passwords in the letter, but it was impossible to confirm it.

This letter cannot be used to provide any evidence based on its contents.

There was no progress in the store.

It seems that everything is just that the Japanese camp is too suspicious and nervous.

But another incident that happened three days ago was shocked by Zhou Yang and Cui Liulang.

The snake head who reported the letter was dead.

And that foreign pickpocket evaporated from the world, and he didn't know how to live or die.

It seems that this person has never appeared in Chang'an.

This is a strange thing.

The Wozheng Camp was established for two years. There have been cases where it cannot be investigated. There have been cases of fighting with various forces in detail and losing manpower. However, there has never been a snake head that died inexplicably.

People like them are the most sensitive to movements and know how to protect themselves the most.

But now, the snake head belonging to Cui Liulang is dead and is found dead at home.

He knelt to the east and his head was cut off.

There was blood falling in the room, and even the beams were splattering.

This kind of tragic situation can be felt even when you read the file, and a sharp murderous aura hits your face.

It is not something that ordinary people can do if they want to cut off human heads.

First of all, there must be an extremely sharp sword that is conducive to chopping.

Secondly, people who use swords must have extremely clever techniques, and swing the sword must cut through the gaps in the human neck bones to be clean and neat.

Otherwise, if you cut the bone with one knife, you will be afraid that your head will not break and the knife will break your mouth first.

The blood splashed on the beam on the scene means that the other party was decapitated with one knife and arterial blood was sprayed out, so that this effect could be achieved.

Moreover, the snake head is not very clever, but he is not a fool. He should not kneel there honestly and beheaded people.

So just thinking about the situation on the scene will make people feel chilled and their scalp is numb.

In my home, I felt as if I was possessed by a demon, and I knelt in the east, motionless, and let someone stand behind me and behead me with a knife.

Blood sprayed on the roof.

The splattering hissing sound was like the wind blew on the face.

No head was seen at the scene.

The murderer calmly beheaded the snake's head and then left with his head.

Su Dawei closed his eyes and listened to Cui Liulang and Zhou Yang, telling the case in a word.

In my mind, the pictures are deducing with the description.

"Where is the case now?" Su Dawei asked.

This is a question to Cui Liulang and Zhou Yang at the same time.

"Engzheng, although there is no evidence now, it is obvious that the Japanese are harboring evil intentions. I think that besides the executioners of Chang'an, there are only those samurai from Japan."

Zhou Yang licked his lips and said, "I heard that they have learned sword skills since childhood. When they became adults, they used prisoners to behead and verify sword skills. Only these people have this ability."

Cui Liulang, who was standing beside him, immediately retorted: "How can I investigate without evidence? Should I go to the Japanese Guild Hall? How do you ask Your Majesty to look at the camp and see our Japanese War camp?"

"you……"

"Enough, don't argue." Su Dawei reached out to press down and stopped the two from continuing to argue.

He turned his head to the silent tall dragon, saying, "Dalong, what do you think?"

Well, this is a very familiar sentence, and it is quite exciting to say.

Finally, I came to Di Renjie's appointment. I was all under my command, and everyone was talking about the case, and I was the leader.

The one-eyed look on the tall dragon's face flashed with a light, and he smiled and said, "There is nothing difficult about this case itself. The difficulty lies in its identity. One side is a Japanese and the other side is a noble man from the Tang Dynasty. If there is no convincing evidence, the case will not be investigated here normally."

"Dalong, do you think the Japanese are secretly doing shameful things by using business as a cover?" Su Dawei continued to ask.

"This is inevitable. The Japanese are very thoughtful, they seem very regular and polite, but they are actually ambitious and have hidden evil intentions."

Gao Dalong continued: "I went to the scene to see that the corpse was not cut off by an ordinary knife, and Tang Dao's wound was not like that..."

"You mean..."

"I didn't say anything, and I had no evidence." Gao Dalong spread his hands to Su Dawei: "My personal guess can't make evidence."

Zhou Yang said on the side: "This is the difficulty in this case. The case is extremely serious and the murder method is extremely bad. We also have enough suspicion, but we just can't find evidence. Now it's stuck in the bottleneck, so it's difficult to continue to investigate."

Cui Liulang sighed: "It really doesn't work. I'm afraid that it's just a headless case that will be successful by those Japanese again. It's a pity that the snakehead under my command has died inexplicably."

Su Dawei listened silently, constantly deducing the case in his heart.

If it was really a espionage by Japan against the Tang Dynasty, then the Japanese knew that the Tang Dynasty was investigating them, so they silenced the snakehead and the pickpocket?

No, not very similar.

There are many ways to kill people, and it is too high-profile to kill people's heads.

The perpetrator is completely a sense of fearlessness or strong revenge, which is inconsistent with the interests of the Japanese.

Could it be that someone from the store in Xicheng City made it?

Su Dawei was not surprised that there were nobles doing business with Japan and even exchanging information.

Before, the Suwo family had secret contacts with the Shandong nobles and the Guanlong nobles, which made Li Zhi very angry.

But there is no evidence...

Su Dawei suddenly looked up and saw Gao Dalong, Cui Liulang and Gao Yang's eyes fell on him.

The three of them had different eyes, but one thing was the same, that is, they all regarded Su Dawei as a life-saving straw.

"You guys, what are your eyes? What are you staring at me like this?"
