"But this person was not caught, and it was difficult to solve it all at once. What secret is hidden?" Guo Jia put two pieces of information together to analyze.

Cao Cao looked at the copy of the "Tao Te Ching" and said, "Fengxiao, look, the ninth word, the word "name" is actually written as tomorrow's Ming..."

While Cao Cao was about to continue talking, Guo Jia seemed to have thought of something, so he immediately took the "Tao Te Ching" from Cao Cao's hand and started to search. After a while, Guo Jia said happily: "Lord, I understand what's going on."

"Oh, Fengxiao, what's going on?"

"Master, this is really clever. You see, there are many numbers in this letter. These numbers actually refer to the number of words in the article. The content in this letter is very short. A few words are: Five-day iron chain test waters. That is to say, we will test waters of iron chain test waters tomorrow."

"But worshipping filial piety, there may not be any words on the Tao Te Ching."

"Lord, there is another sentence behind this information: 'Tao can be told, it is extraordinary', which is the sentence from the Tao Te Ching. I suspect it is used to tell the recipient which book to find it."

"Come here, find me a book on the Analects of Confucius right away."

The entourage immediately found an Analects of Confucius in Cao Cao's study, and Guo Jia began to search for the words on the information here according to the Analects. After writing it out, he found that the five words were: Cao was not killed in seven days. Guo Jia read it and said, "Lord, aren't we going to the water camp to watch the training situation of the water army on the seventh day of the lunar month? Could it be that Cai Mao and Zhang Yun are really against each other? Could it be a plan?"

Cao Cao was also a little confused and said, "This is indeed a coincidence. I also doubt it, but the contents are all our arrangements..."

Cao Cao looked at Guo Jia, and both of them were silent. Suddenly, both of them said in unison: "It's true." Then both of them laughed, and Cao Cao said: "Fengxiao, you say it first."

"Lord, only those in charge of us, Cai Mao and Zhang Yun know about these times. If it is a conspiracy, I think it is impossible. Even if they use counter-espionage strategy, we will investigate. It is impossible that it will really work. Then if Cai Mao and Zhang Yun are fine, this information will not be revealed."

Cao Cao thought it was right after hearing this, and added: "Also, this method of transmitting intelligence is really powerful. Sun Quan could not deliberately reveal such an important method to us. This idea is very valuable."

"Then how to deal with Cai Mao?" Guo Jia asked.

Cao Cao said: "We might as well control his family first, and then tomorrow is the fifth day of the lunar month. We will test the iron chain boats. Then Cai Mao and Zhang Yun will definitely be there. We will also go there suddenly, and then ask someone to kill them on the spot, and then inform the entire army. This will avoid unrest. Now the aristocrats in Jingzhou are a little unstable. If they delay, they will be too dangerous to hold the team and get the support of money and food."

"It's feasible, but are we really not checking it anymore?" Guo Jia was still worried.

"I don't think it's necessary. Jiang Gan said that this information was handed over to Zhou Yu directly by others, which shows the importance of this information."

On the morning of the fifth day of the lunar month, the first batch of iron chains were officially completed. The eight ships were connected together, like a whole. There were basically some shaking on the water surface. Cao Cao looked at the busy navy on the shore. At this time, everything was ready. Even the soldiers on the boat had been arranged, just waiting for Cao Cao to board the ship. Cao Cao and Guo Jia and others did not get on the boat as soon as they were, but stopped on the shore. When Cai Mao heard that the prime minister had arrived, he immediately prepared to come and greet him.

Guo Jia said to Cao Cao, "Lord, Zhang Yun is not here, please find someone to ask!" Cao Cao also felt strange. Cai Mao and Zhang Yun were basically together, so he asked Xu Chu to check. Soon Xu Chu came back and said, "Prime Minister, Zhang Yun is a little uncomfortable today, so he asked him to leave for one day."

At this moment, the messenger reported to him: "Report to the Prime Minister, Cai Mao came to welcome the Prime Minister." Cao Cao ordered as soon as he heard this: "Push me Cai Mao!" As soon as he finished speaking, four personal soldiers ran away from beheading, and then came to the front to banish him, and then pushed Cai Mao out to wait for beheading. Usually, he would wait a moment before beheading, and someone would go to Cao Cao to confirm the order. If Cao Cao regrets it, they would be the one who was unlucky. However, today the personal soldier who was responsible for the execution was a bit exception. He seemed to have not woken up yet, so he pulled out his knife and chopped off Cai Mao's head.

The two personal soldiers next to him who held Cai Mao's hands wanted to stop him, but before he could say it, the chopping was already done. The two began to complain, one said, "Are you stupid? Cai Mao is the governor of the navy? Ah San went to find the Prime Minister to confirm, and you chopped him. What if the Prime Minister figured it out and regretted it?" The other said, "If the chopping is wrong, we two will have to follow you in trouble. Why are you anxious? You can't escape anyway."

"Two, are you finished talking?" Before these two people could react, they cut the trachea of ​​these two people directly, then jumped into the river and disappeared.

After Cai Mao was taken away, Guo Jia began to think about it again and suddenly said to Cao Cao: "Lord, we have fallen into a trap. The letter brought by Jiang Gan should be a trap. I just suddenly remembered an intelligence. There was no department in the Military Affairs Office in Jiangdong called Jinyiwei. This intelligence department called Jinyiwei was directly under Wu Hou. At the beginning, when their personnel were not so capable, we once reviewed it from their mouths."

Cao Cao knew the problem was coming as soon as he heard it, and said, "When Fengxiao means that this information should not appear in Zhou Yu? Is it possible that Sun Quan sent someone to Zhou Yu?"

Guo Jia said: "Lord, if Sun Quan sent someone to Zhou Yu, it would definitely not be the original secret letter, but should have been translated."

"Yes, filial piety is really agile. But it's okay. Someone will come back to ask for instructions again before they execute it, but fortunately it didn't lead to a big mistake."

As soon as Cao Cao finished speaking, a personal guard ran back and asked for instructions: "Prime Minister, do you want to continue the execution?" Cao Cao said: "Bring Cai Mao back, I am just joking with him." The personal guard immediately ran back to pass the order, but when he arrived at the scene, he was shocked. He immediately ran back to apologize, kneeled on the ground and said: "Prime Minister, Chen Si is gone, Cai Mao and the other two have both killed their backs on their backs."

"What? How could such a thing happen? Someone in the army killed his true guards and went to see them together." Cao Cao was also surprised when he heard this. Who dared to be so embarrassed with him?
