"Frozen green" is a deciduous shrub or small tree that grows in a wide range and can be used as medicine, but it is also a common green material in ancient times.

The craftsmen of the Shangyi Bureau had already confirmed that the dye used in the Assassin's bionic camouflage green silk coat was frozen green, and it was a special sprig frozen green produced in the Mengshan region of Qizhou.

Perhaps because of the local climate or hybridization with other plants, Mengshan Frozen Green is slightly different, and the branches are more low, so it is named Twig Frozen Green. However, the color of the fruit is darker, and it is used as a dye, which has a more natural dark green color, and with the addition of other dyes, it also has a darkish-brown effect.

The color of the silk dyed in this way is very similar to that of cypress trees in winter, and it is the best way to use it as a camouflage. This is probably why the Assassins chose this material.

The effect is better, needless to say, it is very proud to be able to deceive the patrol forbidden army. At the same time, they also made another big taboo, ordinary is the quality that a good killer should have, and the utensils he should use should also meet this characteristic, and they made mistakes in this regard.

Standing by the Wuzhang River, Zhao Zheng knew that this was the only and most important clue for him to continue to investigate. The Bianliang Cao transportation water system is developed, and the Wuzhang River is just communicating with the Qizhou generation to the east. Maybe the dyed cloth was sent to Qizhou for transportation, or it was dyed in Bianliang.

All in all, the banks of the Wuzhang River are the places where Bianliang and Qilu are most closely connected, and it is always right to check from here. Especially when he saw that there were many dyeing workshops on both sides of the strait, Zhao Zheng was even more convinced that maybe it was not very far from the truth.

"Fifth son, there are already clues...... Li Yuan hurriedly came and whispered in his ear. Zhao Zheng knows very well that he is now the focus of the people in Bianliang City, and he doesn't know how many pairs of eyes are staring at him.

"Fifth son?" Hearing this title, Zhao Zheng was a little stunned. It's completely confusing.

Li Yuan said in a low voice: "The official family ordered, in the future, the Imperial City Division will call Gongzi that in private!" ”

"Huh!" Zhao Zheng was stunned again, the will of the official family? Zhao Kuangyin: What does this mean? What does the fifth son mean? During the Spring and Autumn Period of the Qin and Han Dynasties, the word "Gongzi" had a special meaning, but in the Song Dynasty, all the children of wealthy families with a little family status could afford this title. But his origin...... Zhao Kuangyin: Is this trying to elevate his identity? Or is it just a simple code name?

Zhao Zheng didn't understand, could it be that he was the light of the country's surname? But it doesn't seem to be able to fight with Zhao Kuangyin, so it has nothing to do with it? The young man who almost became the founder of the country deserves this title, but what is the matter with this fifth-ranked man? Isn't it inexplicable?

"What else did the official say?"

"No more. This is the only command! Li Yuan shook his head, feeling a little strange in his heart. In his opinion, the official Zhao Kuangyin's attitude towards Zhao Zheng is unusual, but he is not so trusting, and it is strange to be a real game.

Hi, who knows about the royal thing? As a guard, knowing too much is not a good thing to be suspicious, and the most important thing is to keep to yourself and do things quietly. But there is one thing Li Yuan is sure of. The fifth son is outstanding, and his future prospects are immeasurable, and it is absolutely right to follow him, but that's it...... I can't get it. Do you have to be not human inside and out?

Zhao Zheng nodded silently, God knows what Zhao Kuangyin thinks, some things can only be asked later. But even if he asked, he might not say. Who made mystery a great feature of the emperor? Unfathomable and unpredictable can make the courtiers awe and even fear, and the Ming monarchs throughout the ages are as good as that.

That's it. It's better to care about the big things in front of you! Zhao Zheng said in a deep voice: "What did you find?" ”

"As Gongzi expected, the Wuzhanghe generation gathered a lot of dyeing workshops, of which there are seven with Qizhou background, but most of the dyes are purchased from Runan, Nanyang, and even Huainan and Jiangnan, and only one is purchased from Qizhou......"

Hearing Li Yuan's answer, Zhao Zheng was stunned, his eyes were full of suspicion, and he didn't even believe it, how could it be such a coincidence? The assassination is not as simple as losing his head, it is to connect the nine clans. It can be seen that the other party is also fully prepared, it stands to reason that all clues should be hidden, why is there such an obvious flaw?

Is this really unreasonable and negligent? Or is the other party deliberately misleading? For a while, Zhao Zheng was a little unsure.

Let's find out for yourself what the hell is going on!

The result disappointed him again, Li Yuan sent a secret agent with rich communication experience clouded leopard to pretend to be a merchant to investigate, and after a clever conversation, the topic finally led to the sprig frozen green dyed cloth.

The shopkeeper grinned and said: "Mengshan frozen green is very good to use in Qizhou, but when I get to Bianliang, I don't know if it's the difference between water and soil or the weather, the color is darker, and there is a little bit of brown and black. But just a few pieces of cloth almost rotted in my hands until last month......"

Having said this, the clouded leopard immediately became interested, and a clue appeared...... Excited, the spy said quietly: "How ......?"

"I, ah, put those cloths outside, thinking that if any guest takes a fancy to it, I can pay a few more money, and I can pay less. I didn't want a guest to see it, but I liked it very much, and I asked for it all...... At that time, I saw that he wanted to buy it, so I had the courage to raise the price, and I didn't want the customer to pay the bill immediately without saying a word, and take the cloth away......"

"Really? Didn't you say that the color is wrong, and the people of Bianliang don't like it? Who will buy it? The clouded leopard feigned surprise and probed without a trace.

"Who knows?" The shopkeeper looked excited, and the goods that were supposed to rot in his hands were shot, and it was for sure.

The spy clouded leopard naturally couldn't give up lightly, and it was another good temptation, but the shopkeeper was probably counting the money that day, and he had no impression of the customer......

The clue was broken......

When Li Yuan regretted coming to ask for guilt, Zhao Zheng waved his hand and said, "What are you wrong? This matter is not easy to investigate, and it is not surprising that the shopkeeper does not remember! ”

"What then? I can't think of such a small talk, but if I take it back to the Imperial City Division for interrogation, I may ...... "Li Yuan has some bad feelings in his heart, and finally has some clues, but he doesn't want to just stop it."

Zhao Zheng shook his head and said: "It may be useful, but in comparison, when people are in a relaxed state, they are not vigilant, and their words are more real." Interrogation may not be useful, and if the shopkeeper babbles nonsense or speculation in order to escape, do we believe it or not? The officials are pressing, and there is no time to go astray right now. ”

"This ......" Li Yuan was speechless, this is a very real problem. Not to mention the Imperial City Division, in the gates of Kaifeng Mansion and various states and counties, there are many cases of bending into tricks and indiscriminately climbing and biting. Other cases are just gone, and they will pass with one eye closed. But this matter must not be sloppy and must be accurate.

I didn't want Zhao Zheng to say suddenly: "But what, let's arrest people first!" ”

"This ......" Li Yuan suddenly had black lines on his head, and said hesitantly: "Fifth son, don't you mean ......"

"Just arrest it, but don't interrogate!" Zhao Zheng smiled, pretending to be profound.

Li Yuan knew a lot about Zhao Zheng's style of acting, and when he saw the expression of the fifth prince, he vaguely thought of something, but he couldn't say it clearly for a while.

"Hmph, if you don't have clues, you have to learn to make clues, no, to be precise, let others take the initiative to show their feet, the shopkeeper is caught, and someone will be very nervous." Zhao Zheng said with a smile: "Sometimes, only when you startle the grass snake can you see the gray line of the grass snake......"

Li Yuan suddenly realized, nodded happily and said, "Okay, subordinates do it immediately!" ”

……

By the Wuzhang River, the shopkeeper who was originally happy to show off his good business and good luck was arrested in a low-key manner. Low-key is relative, not like the Kaifeng Mansion to arrest criminals with great fanfare, but in fact, for a secret agent agency, such an action is already considered high-profile.

As long as you are a caring person, you will definitely notice this move of the Imperial City Division, and it is likely to react accordingly, which is exactly what Zhao Zheng expected.

At the same time, Zhao Zheng was also a little apprehensive, who can say what is going on? It's been tempted, and the result will definitely be there. If the other party is suspicious, misleading, or misleading, the other party is likely to think that he has been fooled, and it is possible to throw out more "clues".

Zhao Zheng hopes more, and is more vaguely convinced, that this matter may be an oversight on the part of the other party. A person who is good at scheming and assassination may be meticulous, but it is difficult to be thorough. He may not be able to understand the many doorways in this dye, perhaps these special cloths are ordinary in their eyes, and they have no doubts about their particularity.

Maybe they inadvertently made a mistake of taking it for granted, thinking that it was seamless, but they didn't know that they had already left a big flaw. Maybe they got carried away, or maybe they were glad and silently watched the situation unfold in the dark, and did nothing.

It's hard to catch a silent snake, but as long as he moves, there will always be traces on the grass. Now all they have to do is to startle the snakes, and the owner of the dyeing shop has been arrested, which may surprise them, and even make many people scramble.

While marveling at the efficiency of the Imperial Castle Division, you must be worried about how much information the shopkeeper has leaked here. A group of ghosts playing conspiracy are very sensitive, if they receive an unsafe signal, will they find a way to remedy it, or kill people and abandon the car to protect the commander?

In short, if the enemy moves me, it will have its own gains. What the Imperial City Division has to do now is to wait silently, waiting for the big prey to show its tail......

Of course, maybe I thought about it too much. It's hard to determine this matter, but it's just like this, it's really possible, coupled with the fact that he has always had a fairly accurate hunch, Zhao Zheng is still quite looking forward to the result! (To be continued......)
