The first thing underground intelligence work focuses on security. Without security, even if the intelligence network is large, it may be pirated by the enemy overnight.

Therefore, at the beginning of He Qing's tenure as Sima of the Han Central Army, he paid great attention to the security of the intelligence network. Among the five intelligence personnel who were in contact with He Qing, only two knew He Qing and knew He Qing's identity information.

Moreover, these two are He Qing's confidants and are absolutely loyal. Even if they are exposed, they will not give He Qing to death. They are people that He Qing can absolutely trust.

The other three are military marquises in the military, each responsible for a stake. They and He Qing have never met each other. The contact information and intelligence transmission between them are all contacted through several special methods. Once a problem arises, He Qing can cut off the contact information and interrupt the contact in a timely manner. Even if the Shu army continues to investigate, there will be no trace.

In this environment, if you want to survive, you must be careful and cautious. Even if any slight negligence is a little careless, it may cause immeasurable losses. Those who are careful to sail for ten thousand years and do underground intelligence work must always keep this in mind.

He Qing's caution did escape many crises for him. Three years ago, a military marquis code-named Canglang was captured and turned against the Shu army. The Hanzhong Intelligence Network suffered the greatest damage in history. The branch intelligence network under Canglang was almost devastating. Canglang also colluded with the Shu army to set up a trap and tried to capture the Hanzhong Army Sima Qingqin.

Qingshan is He Qing's code name, but Canglang only knows Qingshan and does not know He Qing's true identity. However, he has a contact information with He Qing. Canglang and the anti-espionage department of the Shu army set up a trap and used an important information as bait to catch He Qing.

But He Qing was very vigilant. Although this information was very important, He Qing did not take the risk to take it. Although Canglang's surrender to the enemy was secret, some clues were still revealed. He Qing did not make an appointment by himself, but instead paid for an ordinary person to go there. The Shu army laid a net of heaven and earth, but in the end he only caught a small fish, which made the captain who was in charge of the arrest operation jumped straight.

He Qing escaped with his keen sixth sense, and within the next six months, he found an opportunity to get rid of Canglang. Of course, He Qing would not show mercy to such a scum who betrayed the organization.

The principle of an intelligence organization is that you can choose to be loyal or choose to withdraw, but betrayal is never allowed, because any betrayal will cause serious damage to the organization and endanger the personal safety of other intelligence personnel. The organization will never indulge such traitors.

But often a spy is exposed, either to die or betray, and there is no third way to go. Moreover, once they choose to betray, they will become more vicious and crazy, and keep biting like a mad dog.

For such mad dogs, intelligence organizations will of course spare no effort to eradicate them, because betrayal is the most intolerable behavior.

Eliminating Canglang not only makes the Shu army intelligence personnel relatively safe, but more importantly, it can shock those who have two ambitions and prove that they will never tolerate traitors.

However, after this incident, the Shu army also learned about the existence of Qingxiao and spared no effort to launch a large-scale search, which made He Qing more careful, not only to complete the intelligence collection task explained above, but also to avoid exposing his identity.

The exposure of a Cang Wolf caused a severe blow to the Hanzhong Intelligence Network. If something happened to Qingxiao, who is the Sima of the Mid-Secret Army, it would be a devastating blow to the Wei army's Hanzhong Intelligence System and would probably not be able to recover within a few years.

Therefore, He Qing needs to try his best to ensure his safety. No matter what, there is no accident on his side. What's more, the Wei army will launch an attack on Shu. At this critical moment, it needs to get strong support from the Jianjun Office. Without the accurate information provided by the Jianjun Office, the Wei army commander would not be able to formulate a combat plan, and the entire army was like a blind man touching an elephant.

At this time, the senior leaders of the Wei army gave him a new task, to alienate the general of the Shu army Han and destroy the Shu army's defense plan.

This task made He Qing feel a little worried. Compared to spying and collecting intelligence, the difficulty of this disagreement task will be increased exponentially.

Fortunately, Deng Ai should also be able to realize the difficulty of completing this task, so he did not make rigid requirements. He just asked the Hanzhong Military Office to do his best to do it. If it can be done, it would have nothing to do.

Although Deng Ai asked this, He Qing must of course do 100% of his efforts to complete it. He must do it if he has the conditions, and if he has no conditions, he must do it if he has the conditions.

In fact, He Qing was in Hanzhong. Based on the information collected from multiple aspects, it has confirmed that there are some irreconcilable contradictions between the Hanzhong Governor Yan Yu and the generals of Hanzhong. What He Qing has to do now is to find a way to light the fire, add some firewood, and then fan the wind to make the fire burn more vigorously.

The generals in Hanzhong are all the direct descendants of the general Jiang Wei. Although Jiang Wei is no longer in Hanzhong now, it is not that he can suppress these generals in Hanzhong by simply transferring someone. If there is such a person, he must have a status in the Shu army that is not inferior to Jiang Wei. He has great military achievements and a high prestige. Only such a leader can convince the generals in Hanzhong.

But what is Yan Yu's identity? His behavior of defecting to the eunuch Huang Hao has already made many generals of Shu dissatisfied. Although Huang Hao is favored, his eunuch's identity is enough to be despised by those loyal to the Han Dynasty.

In addition, Huang Hao abused power and treason, engaged in corruption, abused the law, and confused the court. He did everything that was angered by heaven and others. All loyal and upright people hated Huang Hao to the core. Yan Yu actually recognized the thief as his father and was willing to be Huang Hao's minion. No matter Yan Yu's ability, his character was no longer favored.

Therefore, although Yan Yu is the governor of Hanzhong, he has many disagreements with the generals of Hanzhong. No matter how powerful Yan Yu is, no one dares to obey him. Yan Yu's position in Hanzhong is quite embarrassing.

However, it is not easy for He Qing to fan the flames and provoke the relationship between Yan Yu and other Shu generals, because He Qing wants to do this, the biggest difficulty is how to get close to Yan Yu. After all, He Qing's superficial identity is just a businessman, and his status is very different from Yan Yu. He doesn't even have the chance to see Yan Yu, so how can he instigate him?
