More than 700 miles from Handan to Daliang are all traveling against the current, namely Fei, Ganhou, Neihuang, Xiyang, Qianyi... Most of the cities along the way are broken, and you have to go to Wanjin, the river channel enters the Dongjun, and the Heneijun, and the two banks of the river to see the city and the houses.

This is Qin County. I saw the boats of the Chu army from afar. The guards hurriedly asked to beat the drums, and the gangs quickly closed the door. Only the villages and fields outside the city could see the common people standing on the shore without fear. The boats of the Chu army passed through the river, and they were no longer surprised. Even if the warships stopped, they would not be scared to run away immediately. There was a salt and iron smuggling area on both sides of the shore. Even if the salt and iron dealers who came up wanted to sleep in the neighborhood for a night, they would not object.

"Why don't you migrate these common people?" Xiong Jing on Wang Zhou put down Lu Lijing and asked in confusion. The population has become a flaw for the Chu State. Thousands of boats transported twice, and only more than 400,000 common people were transported, which was far lower than Xiong Jing's psychological expectations.

"If the common people on the river bank are there, salt and iron can be imported into Qin territory, and if the common people on both sides are not there..." Nao Xin replied. He belonged to the Zhibi Office and was very clear about the smuggling of salt and iron along the river.

"Oh." Xiong Jing laughed. He only thought about the population, but he forgot about this.

"The people in Zhao are strong and the Qin people will be unable to use Zhao for themselves." Any lost places will be arranged and established a network of marquis spies in the local area. If Qin appeases Zhao, it will be difficult to eliminate these marquis spies, and it will inevitably cause trouble and chaos over time; if Qin cleans up Zhao for a comprehensive period of time, Zhao will be panicked for a long time and the soldiers will be difficult for them to use.

The Hou spy war appeared hundreds of years ago, and Sun Tzu's Art of War was useful, but it was the first time that the Hou spy war was carried out on a large scale, especially in various counties and towns, burying soldiers, armor, gold and silver. Nao Xin personally directed and participated in this matter, so he was confident. Xiong Jing was expressionless when he heard this. He knew that the Hou spy war was effective and very important, but he was a little repulsive about it.

"How about Mr. Changwen? Is there an unscrupulous uncle?" He asked another thing, especially Mi Ren, the cheap father-in-law.

"All of them are in prison, and it is reported that they have no worries about their lives for the time being." Nao Xin said. "The emperor has never asked his brother to intervene in this matter, and the case has gradually become clear. Therefore, some people in the Zhao clan plead for Changwenjun and said that they must not be punished without guilt. This is inconsistent with Qin law."

Qin was a legal country. Although the King of Qin was above the law, the King of Qin could not fight against the existing law. His power was still restricted by the legal system, even if the law was formulated under his advice. The lower-level legal officials always had laws to follow when handling cases, and the law enforcement must be strictly enforced.

In other words, this is not an era of the word "official". The Qin King himself must follow the laws formulated by the Qin King. Everyone believes that observing the law can make the country strong, rather than just treating the law as a tool of power. They will not say that you break the law and that you do not break the law; nor will they say that you are innocent and that you are guilty. This is a true society ruled by law.

The Tingwei Mansion could not find evidence, so the case of Changwenjun Xiong Meng was delayed until now and could not be closed. According to Zhao Zheng's intention, of course, it is best to execute him. He hated all Chu people, let alone Xiong Meng was also the prince of Chu. But with Qin law, he could not be executed without guilt. If he wanted to kill, he could be killed with the royal power, but he could not be killed with Qin law. If Qin law kills people, he would be guilty.

Xiong Jing understood Qin's politics, but did not understand Qin's rules. Seeing that Xiong Meng could not die, he immediately said, "Can you save Qin?"

"No." Nao Xin shook his head, "The Qin State has changed the number of news. Most of the officials who went to me who went blind to me would be resigned. Unless they robbed people, they would be helpless. If they rob people, they would have been strictly prevented from entering and leaving Guanzhong."

Last year, the Chu and Zhao cavalry attacked Xianyang, and Xiong Jing rushed to Weinan to snatch Mi Xuan. Most of the officials along the way were removed from office. The reason why he was successful was that in addition to knowing the infiltration of the foreign ministers, the Qin people themselves were negligent, and it was completely impossible to take such a snatch again. The pass system, the talisman system, and the people related to this were different.

"So difficult?" As a king, Xiong Jing does not need to understand the specific details, and he will only be informed of the details when he delves into it.

"That's right." Nao Xin replied. "All the officials who had been bribed before were replaced, and it would take time to buy them again. If they were too hasty, they would cause major events to be leaked; the talismans were all changed, and it would be difficult for the Qin people to carve their teeth for ten years, so it would be difficult..."

"Caring teeth?!" Xiong Jing was very surprised when he heard about Caring teeth for the first time.

"The king doesn't know..." Nao Xin was also a sign of a strife, but he was not surprised. Xiong Jing was a person who made decisions, not a craftsman who made bamboo slips. Moreover, the Chu State had used Chu paper on a large scale, and the dark patterns on Chu paper replaced the carved teeth on the bamboo slips. He explained: "What the king saw in the bamboo slips often looked at the front of the words, and if it was not intentional, it would not look at the side."

"Yes." Xiong Jing nodded. Most of the time he looked at the words on the bamboo slips, and would not look at the side without words.

"Baby slips are different from Chu paper. Even if they are written, they can be scraped off and tampered with the words. If the letters are written, the upper and lower sentences are not understood, and the modification is useless; if the treasury is recorded in the treasury, the money, grain, soldiers and armor, the treasury is written into one million stones, and the 7,000 sets of armor are replaced into one thousand sets of armor, which is a thousand gold medals." Naoxin continued. "Therefore, all treasurys have carved teeth on the side. Since there are carved teeth, others should not know the words that their teeth are against. If anyone knows them, they will be executed."

"So that's it." Xiong Jing suddenly realized. The teeth carving that Naojiu mentioned was the earliest large-scale cryptographic system used in East Asia. The most valuable thing Xiong Qi gave to Zhibian is the system's engraving template and rules for using the engraving. In order to standardize the engraving, there are both engraving pieces. There are multiple sets of engraving pieces, and certain rules must be followed for the use. Both of them know that they can forge the Qin Dynasty's talisman.

"You can't, you can't..." Xiong Jing seemed a little anxious. He thought of something, but he couldn't remember it for a moment.

"There are dozens of sets of talismans in various countries, and the time is different, and the number of talismans is different; the number of talismans is different; the destination is different, and the engravings are different; or there are others who do not know about it, and the engravings will also be different. Forging them will be observed by the Qin people." Naojiu said helplessly. "The previous talismans were issued by the Prime Minister's Office, but now the talismans have been issued by the Guowei Office. Knowing that the other department can only try to collect talismans in Qin people and record them to break the method. This will take several years or ten years."

Naojiu's words were very tactful. In fact, what he meant was that if there were no inner ghosts, the Qin Dynasty's tooth engraving password system would never be able to be broken. After he finished speaking, he saw Xiong Jing silently and said, "Changwenjun has nothing to do with Tongchu. In a while, if the Tingwei Mansion cannot prove his guilt, the Qin King will not want to be punished without guilt and can only release him and return home. But..."

Xiong Jing never thought that there was a systematic cryptographic system in this era, and he knew how to rotate. This was the pre-Qin period two thousand years ago, not the cryptographic machine of the Germans during World War II, but this is a reality. Liye Qin bamboo slips, Juyan Han bamboo slips, Xuanquan Han bamboo slips, and all the important parts of the official bamboo slips have teeth on the side to prevent someone from tampering with and forging. Although it has not yet developed to the stage of pure tines, it is not far away. The key is that these tines are systematic and counterfeiting are almost impossible.

"How is that?" asked Xiong Jing, who came to his senses.

"The king's uncle may be difficult to release." Nao Xin said. "I know that the minister cannot save him from Qin."

"Yeah." Xiong Jing was speechless. This was the omission. He brought the entire Mi clan back to Chu, but it was only the part of the people in Xianyang. The relatives who were not in Xianyang were still in Qin, including Mi Ren, who was in Chu with Xiong Qi.

"I think I should send someone to Qin to ask the King of Qin to send the king's uncle to Chu State." Nao Xin suggested that this is the only way.

"What does the King of Qin want to get?" Xiong Jing asked.

"I don't know, I think..." A thing flashed in Nao Xin's mind. If this thing was given to the King of Qin, the King of Qin would definitely send Mi Ren to Chu State.

"What do you think?" Xiong Jing asked.

"What do the King thinks the Qin people fear me the most?" Nao Xin asked.

"Architecture?!" Xiong Jing's solemn expression changed suddenly, and he became amused and crying. The Chu army swept the Qin State by gunpowder cannons. Isn't this too much for giving the cannons to Zhao Zheng? Besides, artillery, like the giant armored soldiers, are bound by the law of the Great Iron passed several years ago. It is illegal to import it to Qin State. He does not have to go to jail for breaking the law, but those who do this must go to jail.

Let’s talk about giving Qin cannons and then bombarding the Chu people, which Xiong Jing didn’t want to see. Mi Xuan was his heart, and the Chu soldiers were at least the flesh on his back. Soldiers could sacrifice, but they could not sacrifice like this.

"If you are not honest, you should violate the law of Chu." Xiong Jing sighed.

"This..." Nao Xin saw Xiong Jing sighing, knowing that he felt sorry for the queen, he couldn't help but say, "However, the method of the giant iron does not mention the artillery."

"Unspeaking the cannon?" Xiong Jing was stunned. He thought about it carefully. When the giant iron law agreed, the cannon had not yet come out, and it was indeed unspeaking the cannon. At most, it might have brought a Jing crossbow and a catapult.

"No," Xiong Jing said. "I will use artillery to the Qin people, and the Qin people will use artillery to kill our soldiers..."

Nao Xin also had a more mouthful. Since he had a more mouthful, he could only continue: "The artillery was made by the king, so it cannot...it cannot make it useless?"

"Useless?" Xiong Jingzhen didn't think about this. If he wanted to make the artillery useless, there was a way. For example, when building a mansion and cannon, he deliberately thinned the barrel and exploded the barrel immediately after several guns; or he could install less gunpowder and add impurities to the gunpowder to make its power limited;

Or like Matteo Ricci and Johnson Chan, they taught the Ming and Qing dynasties to cast cannons, but the cannons were not given with quadrants. When translating artillery materials, they deliberately erased the data related to aiming, so that pagans would not be able to hit the cannons in the future.

Nao Xin's reminder opened Xiong Jing's imagination. Although he did not trust in doing this, he needed to think about this matter carefully for Mi Xuan.
