Luo Shixin stored the secret envelopes Li Shimin gave him. Although these letters further verified the correctness of their ideas, there was still no substantive evidence.

Wang Junkuo was one of the most influential figures in the Tang Dynasty at this time and a great hero who quelled the rebellion with his own strength. It would be almost impossible to pull him off without any substantial evidence.

Just as Liu Yanke said, the trick to solve the case is bold and assumptions are made and carefully proved.

For this reason, Luo Shixin deliberately asked Liu Yanke to investigate the situation at Cui Dunli, but the results were not optimistic.

Cui Dunli was very cooperative at first, but he realized that Liu Yanke's problem was sensitive. He was not understanding the situation, but intending to find Wang Junkuo's fault. He immediately issued an order to expel Liu Yanke and drove Liu Yanke out.

"What a boldness!" Luo Shixin glared at his eyes in anger. Although Liu Yanke's official position was small, he was the one who was ordered to investigate. Cui Dunli drove Liu Yanke out like this, not only humiliating Liu Yanke, but also slapped him as the Minister of Justice. "My subordinate dares to drive him away. A small messenger is so arrogant. I really don't know how many eyes Mr. Ma has!"

Liu Yanke was very open-minded and said awkwardly: "The people in the public affairs are not small anymore!"

"Hmph! I'm only a fifth rank, how many ranks are I better than him!" Luo Shixin said without hesitation: "If you don't want to eat toast, then you will be punished. The visitor brought Cui Dunli to the Ministry of Justice to ask about the case. If he doesn't force him to capture him, it doesn't matter if he's more serious. It just happens to vent his anger to our Liu Lingshi. A small messenger, how dare you make a big deal?"

Liu Yanke was a little dumbfounded. The fifth-rank official of the public servant of the public service was not considered a big one. But it was definitely not small, especially his power. The public service person held the imperial edicts and submitted memorials. The task was to convey the orders and initiate the memorials inside and outside. He was a close servant who was directly in contact with the emperor. Throughout history, officials who had been able to talk to the emperor for a long time cannot be determined by the size of the official position.

Wouldn't he be afraid of offending Cui Dunli and being worn in small shoes in the future?

But seeing Luo Shixin risking offending Cui Dunli, he was also moved in his heart.

However, this matter was not as big as expected. Cui Dunli dared not to sell Liu Yanke's face, but he did not have the courage to not give Luo Shixin this face: the closer he was to the emperor, the more he could feel the half-child care of Luo Shixin and the respect of Prince Li Shimin. Before he had to force him, no one was willing to offend a celebrity-heavy official like Luo Shixin. Although he was a little angry, he could only come to the Ministry of Justice for a trip.

Faced with Cui Dunli's unexpected cooperation, Luo Shixin was not willing to make trouble and handed him the secret letter he sent in Youzhou, "Is this a letter you wrote to Your Highness from Youzhou?" He already knew that the letter was sent by Cui Dunli through Wang Junkuo's channels. There is no key evidence at present. He had no way to start, so he could only peel off the thread and draw a cocoon and examine everything related to Wang Junkuo one by one.

This day, the net was vast and sparse, and Luo Shixin did not believe that Wang Junkuo could set up such a big situation and be able to be seamless, with no flaws in every step and every link. If there was no flaw in it, it could only mean one thing, their bold imagination was in the wrong direction. Wang Junkuo was not the mastermind behind it.

Cui Dunli received the secret letter, but was shocked. Li Shimin actually handed over his secret letter to Luo Shixin. This was undoubtedly a kind of support for Luo Shixin's investigation of Wang Junkuo. A little bit of sadness gradually surged in his heart. "The king and the governor were both loyal and righteous, and made such great contributions, but he was jealous and suspicious. How injustice is this." He opened the secret letter and saw that it was written by himself. He couldn't help but say in anger: "This letter is indeed what I learned about the King of Lujiang.

He had the intention of rebelling and was writing it in person when he rebelled in advance. The situation was critical at that time. If it weren't for the King's Governor, he would have been afraid that the Tang Dynasty would have started to rise again. The Shangshuo captured Liu Heita and the Knife Formation of the Mo Dao defeated the Turks. This year, he even went north to Shuofang, and had no one to fight against the northern border. Capturing the Turks Khan alive was a great achievement. In terms of the age of the general, only Huo Qubing of the Han Dynasty could compare with him. The strong reputation was far above the King's Governor, so why bother with the King's Governor's contribution? "

Luo Shixin laughed: "You are the ones I said I was jealous of Wang Jungu's achievements to investigate him?"

"Isn't it?" Cui Dunli is a pedantic but square scholar. Such people like to be stubborn. He can sacrifice his life for his beliefs, and face severe torture. He has the integrity of Jiang Jie, and will not reveal a word by word when he dies. However, he is extremely stubborn about what he believes in. He recognized Wang Junkuo's great kindness and righteousness in his heart. He felt ulterior motives about Luo Shixin's actions and actions, and said, "The King of Kings is loyal and courageous. When it comes to credit, he may not be as good as Lord Shangshu. Compared to character... Humph, that's a difference."

Luo Shixin was stunned. Although he was not sure that Wang Junkuo was the real mastermind, he empathized with Wang Junkuo's character, and compared a guy who was inferior to a prostitute with character. This... was even more excessive than scolding him.

"It's just you, a pedantic scholar, who is selling it and still counting money for others." Luo Shixin was not stingy with his ability to ridicule. If Cui Dunli had not been a scholar who had no choice, he would have wanted to beat him up.

Cui Dunli was so angry that he trembled with anger when he saw Luo Shixin: "A rash man, he has no official demeanor at all, and he knows how to show off his verbal advantage. I, I want to study your book, your book." He said as he wanted to take the door and leave.

Luo Shixin stepped in front of him, and said as if he was a chicken, and said, "Where is you who is the Ministry of Justice? Before you finish asking, just stay with me honestly. After asking, you can only follow me ten books." As he said that, he threw him on the ground at will.

Unexpectedly, Cui Dunli fell a rolling gourd directly, and a small object stored in his belt also rolled out.

This is not Luo Shixin, but he is not deliberately making things difficult for Cui Dunli, but he didn't expect that Cui Dunli's feet were so weak that he could not grasp the balance. However, he didn't know that when he was tortured, Cui Dunli was injured all over, including skin and flesh and bones. However, one of his feet was injured, so he couldn't grasp the balance and fell to the ground.

Luo Shixin scratched his head and wanted to help him, but he asked Cui Dunli to push it away. He was too lazy to use his hot face to stick his cold butt, and helped pick up small underground objects: there was a seal and a clay box. The clay box was in the style of a small iron box. Because it fell to the ground, the lid flew out, and there were a little glowing gold powder on the ground.

Picking up the ink mud, looking at the old-style ink mud box, my mind suddenly flashed like lightning, and I forced Cui Dunli to lift it up and said, "Do you carry this ink mud with you? Are you using this ink mud in Youzhou?"

Cui Dunli's feet were thrusting and thrusting. Seeing that Luo Shixin had no intention of apologizing, he was so savage and stubborn, he shouted: "I will..."

Before he finished speaking, Luo Shixin raised him up again, with anger in his eyes: "If you want to sue, I don't care. Damn, can you tell me the severity of the matter? I'm asking you if I'm the Minister of Justice, and then say goodbye to me, believe it or not, I'll throw you into the prison of the Ministry of Justice."

Cui Dunli opened his mouth, but when he saw Luo Shixin's fierce and unreasonable eyes, he swallowed all his words of resistance and replied, "Yes, as a wise man, you may find the situation at any time and anywhere. Ink paste is a must-have item. This is the latest ink paste, which is not easy to shrivel and fall, and can last for a long time. It is much easier to use than ordinary ink paste."

Luo Shixin put Cui Dunli down and said, "Then look at the ink on your secret letter..."

When Cui Dunli fell to the ground just now, Seishen also came out. He immediately bent down to pick it up when he heard this. After a closer look, his expression changed drastically and he cried in a low voice: "How could this happen?"

Luo Shixin sneered: "What do you think?"

The ink they mentioned was not the kind used for seals in later generations. Its essence is the same but its meaning is very different.

Ink mud in this era was like a clay ball. It was made of clay balls and was soaked with water when used. At that time, official documents and letters were written in lacquer on bamboo slips and wooden tablets. In order to prevent private dismantling during the process of secret leakage or transmission, a piece of wooden block dug with square grooves was added outside the written bamboo slips, and then tied them together with a rope. Then put the knot in the square groove, add a ball of wet mud seal, and then stamp it with a seal and send it out as a seal mark. This method of sealing secret letters is called clay seal.

However, in the Sui and Tang dynasties, inks had a new transformation. Because with the development of technology, paper became popular during the Sui and Tang dynasties, and all public and private letters were replaced with paper, and bamboo slips were officially abolished. The old method of using clay to seal letters was no longer applicable, and smart people invented new inks made of cinnabar, which had the same effect as inks in the past.

However, because it is the latest invention, there are many problems: it is easy to fall off after solidification, it is easy to crack after dryness, etc. However, the wisdom of the ancients was endless. They overcome difficulties one by one and developed new ink paste suitable for paper seals. This new ink paste was also popular all over the country, especially the necessary items in the officialdom of the Tang Dynasty.

However, the new ink paste is not perfect. In Chang'an, a man who made ink paste invented a kind of gold paint ink paste. The gold paint ink paste is better than the red paint ink paste, but it has not been promoted because of its high cost and low yield. Most of the upper-class people in Chang'an like this kind of gold paint ink paste and switched to gold paint ink paste, and Cui Dunli is one of them.

The biggest feature of gold-lacquered ink is that it is soft and will shrink after dryness. It is not as hard as a stone like a vermilion ink, and it can even cut hands...

The ink has been replaced, which means that before Li Shimin got the secret letter, someone had a secret letter... (To be continued, please search for Astronomy, novels are better, updated and faster!
