On the eve of the war, intelligence work is indispensable, and in this regard, Su Tiancheng has some headaches.

To say that he attaches great importance to intelligence work, Qu Qingze is specifically responsible for intelligence work, and he also uses the Jinyi Wei dark line, under normal circumstances, this is unlikely, but Daming's intelligence work has a fatal flaw.

The main work of the Jinyi Wei dark line is to keep an eye on the officials, especially the officials and vassal kings above the third grade, their actual task is to maintain the imperial power, that is, to keep an eye on the officials for the emperor, as for other aspects of the intelligence, few people care, Su Tiancheng mastered a part of the Jinyi Wei secret line, and made a special request, mainly to grasp the information of the Liukou and Houjin, in terms of mastering the intelligence of the Liukou, the dark line is doing a good job, but in terms of spying on the intelligence of the Houjin, it is very unsatisfactory.

There is another problem with the intelligence work of the Ming Dynasty, that is, the intelligence that has been spied on has to be presented to the emperor, and then the emperor comes up to make a decision, and the departments and officials who urgently need intelligence may not be able to make a decision.

As for the pedantic understanding of the court officials, it has greatly hindered the development of intelligence work.

All these aspects have a real impact on intelligence work.

On the other hand, the intelligence work of Houjin is very different, Huang Taiji attaches great importance to intelligence work, and is willing to delegate power, Huang Taiji can contact ministers and generals at any time, and can decisively ask for departments and individuals who obtain intelligence, and make decisions quickly. Moreover, the information obtained by Houjin can go directly to the relevant departments, and it is precisely because of this that Houjin obtains information from a wide range of sources.

In the process of historical development, some historians always like to comment, saying that there are many traitors in the Han nationality. This is the inferior nature of the nation, and the rest of the ethnic minorities have very few spies, but Su Tiancheng doesn't see it that way.

There are spies everywhere, and spies have their own understanding, perhaps because they are dissatisfied with society, maybe they are for a better life, or maybe they are for money, whether they are Han or ethnic minorities. There are all this kind of people, but the number of the Han nation is large, so there are more spies exposed.

The Liukou has been completely wiped out, and today's intelligence is mainly aimed at Houjin, and the role of the Jinyi Wei dark line is not great, at this time, the main source of intelligence. Originated from the mutual market, the information sent from Anning Fort and Jingbian. reflects a lot of information about Houjin, and through this information, Su Tiancheng was able to analyze Houjin's actions.

Although he is a person who crosses, Su Tiancheng is not very familiar with Houjin, besides, after crossing. History has changed, many new situations have emerged, and what to do next, relying on historical knowledge alone is certainly not enough.

Guanning Jin defense line. It is a big trouble for Hou Jin, such a place, it is impossible to have Hou Jin's spies, and the imperial court's management of the households here is not harsh, ordinary people come and go freely, which is different from the mainland.

The situation in Liaodong has always been very tense, Houjin entered the customs several times, looted a large number of Han people, some Han people came back later, and no one doubted that these people could come back, and no one cared, what did these people do when they came back, in fact, some people have begun to work for Houjin and become a member of the intelligence network.

These people are at the bottom, and it is impossible to know how much confidential information they have, at most they can obtain some information about the garrison, but the leakage of another kind of information is very harmful, that is, the leakage of information by officials.

The secrecy system of the Ming Dynasty is not flattering, the party in the court is fierce, and there are many times when there is a situation of rectification, which requires the echo of the periphery, a lot of information, in this process, unconsciously leaked out, including the big things discussed by the court, no official thinks this is abnormal, everyone is used to it.

This situation also exists in Jinzhou, Ningyuan and Shanhaiguan, where the vast majority of them are soldiers, and the soldiers are rough in nature, and they lack a sense of secrecy.

Therefore, in this intelligence war, Su Tiancheng is in a disadvantageous position.

The information provided by Huang Zaisheng has become an important source for Su Tiancheng to directly obtain information, involving all matters related to Huang Zaisheng, the entire Jiangning camp, only Su Tiancheng and Qu Qingze know the Tao, Su Tiancheng once told Qu Qingze that no information about Huang Zaisheng is allowed to be leaked, even the imperial court is not able to know the Tao.

Su Tiancheng's face was very gloomy, and when Qu Qingze came in, his face was also a little pale.

"Lao Qu, you found out our information, how did you leak it?"

"The specific situation is not very clear, after the sergeants of Shanhaiguan and Ningyuan entered Jinzhou City, the management of these sergeants was very lax, and they often went to Qinglou and restaurant, and the lower officials estimated that the information was leaked out of these places."

"Then tell me, do you need to remind Zu Dashou and Wu Sangui to strengthen the management of sergeants."

Qu Qingze shook his head.

"My lord, the lower officials think that such a method is not too effective, 100,000 sergeants, if they want to keep it completely secret, the possibility is not very great, at the beginning of the year, the lord once said that he would attack Dalinghe City, and Houjin also obtained information in this regard, and now it is suddenly kept secret, which will arouse Houjin's suspicion."

"At this time and at that time, the situation at the beginning of the year was different, in order to attract Houjin's troops, and now that this goal has been achieved, the relevant troop arrangement needs to be kept secret, but the current situation is that nothing can be kept secret."

It turned out that Su Tiancheng's transfer of defense, that is, the matter of requisitioning and transferring 100,000 border troops and 50,000 Jiangning battalion soldiers, was obtained by Houjin, and Huang Taiji had begun to attach great importance to it, and Houjin also began to recruit and transfer the Eight Banners Army, making all preparations, and the Houjin sergeants stationed in Dalinghe City suddenly became nervous.

Huang Zaisheng and Hushi's intelligence all talked about this situation.

If you can't do a good job of keeping it secret, the next step, the specific arrangement of troops, may also leak out, if Houjin fully knows this information, it will definitely be disadvantageous to attack Dalinghe City more.

But this problem is really difficult to solve, Jinzhou has concentrated so many people, it is impossible to find out the location of the intelligence leak, the inspection team has been established, but for the sake of stability, there is no large-scale action for the time being.

"My lord, I think the lower officials can spread some false information through these channels."

"Well, tell me, what kind of false information is spreading."

"For example, the arrangement of troops, such as the time of the attack, etc., these pieces of information should be top-secret information, if it is leaked, for example, it will arouse the great attention of Houjin, but these information will soon be able to show that it is false, so true or false, Houjin must be puzzled, and he will not be able to make an accurate judgment."

"There is some truth, this matter, you arrange it, implement it immediately, I think it will leak one aspect of intelligence, about the arrangement of the arrangement, Houjin does not know the way, we have mobilized 100,000 border troops, that is to say, the main attack task, is 100,000 border troops, Jiangning battalion as a reserve force, this kind of intelligence, Houjin must believe, including Huang Taiji, will think that this is my need to preserve the strength of the Jiangning battalion, so that the border army becomes cannon fodder."

"Okay, I'll arrange it right away."

Soon after Qu Qingze left, Hong Chengchou came.

"My lord, the 150,000 troops have all gathered in Jinzhou."

"Tell me about your setup."

This time, it was the real arrangement of the troops, which was mainly considered by Hong Chengchou.

"Xia Guan has thought of a plan, please take a look."

Hong Chengchou walked to the front of the sand table.

"Dalinghe City is forty-six miles away from Jinzhou and twenty-two miles away from Songshan, it should be said that Songshan is the forefront of my Ming Dynasty's confrontation with the Later Jin, and the 150,000 troops should be gathered in Songshan, relying on Jinzhou behind them to launch a general attack."

"The tactical arrangement is divided into two parts, the first part, to clear the strongholds on the periphery of Houjin, that is, the defense line one mile away from Dalinghe City, the offensive in this regard, Wu Sangui is directly responsible, it is necessary to eliminate the outlying strongholds within two days, this is crucial, it is convenient for the layout of the artillery battalion, the consideration of the lower officials, no matter how much sacrifice is paid, it is necessary to pull out the strongholds on the periphery, it is estimated that a certain price will be paid, there are red-coated cannons in Dalinghe City, and the lethality is still very great."

"The second part, surround Dalinghe City, launch an attack, the main attack is directly responsible for the Jiangning battalion, Zu Dashou assists, Wu Sangui is responsible for blocking Houjin's reinforcements, in the Xingshan area, occupy a favorable terrain, once we start to attack Dalinghe City, Houjin will definitely send reinforcements."

Su Tiancheng interjected.

"Do you think that the border army led by Wu Sangui will be able to block the reinforcements of the Houjin Eighth Banner Army?"

"This, the possibility of success in blocking is not very likely, the combat effectiveness of the border army and the Eighth Banner Army have a certain gap, coupled with the fear formed over the years, I am afraid that it will not be able to block for a long time."

"In other words, Wu Sangui's blocking in Xingshan has no effect, it's just a show."

Hong Chengchou nodded.

"Lord Hong, such an arrangement, it is absolutely impossible, Houjin reinforcements are certain, Wu Sangui led the border army to block in Xingshan, it is impossible to succeed, but the army is hopeful, there is no worries, if this blocking arrangement, there is no effect, the army will immediately fall into passivity, so my consideration, do not block the Houjin reinforcements."

Hong Chengchou was very surprised, he didn't know how Su Tiancheng planned it, if he didn't block it, wouldn't Houjin reinforcements go straight in, and it would be more passive.

"The battle to attack Dalinghe City will end in two days, the first day will pull out the outlying strongholds, and the second day will take Dalinghe City, and after taking Dalinghe City, the army will face the reinforcements of the Houjin Tartars head-on." (To be continued......)
