Zhou Huchen's martial law order could not be implemented thoroughly, because the defense area of Jiangfang was too large, and there were always loopholes to be found.

However, Zhou Huchen had to do it, because he knew how powerful the "fifth column" was. The so-called "fifth column" is synonymous with spies, and it just so happens that Zhou Huchen is familiar with the history of this "fifth column" and knows how powerful it is. This martial law is just a precaution, it is certain that Jiannu has spies to come to Jiangnan, and Zhou Huchen's liliang is definitely not enough, but this work must be done.

In the original battle of Nurhachi's troops to Quang Ninh, every war had the shadow of the "fifth column" of Jiannu. From Fushun to Qinghe, from Salhu to Kaiyuan and Tieling, from Liao, Shen to Guangning, along the way, every recorded war has the cooperation of internal traitors, without exception. These spies either opened the gates, defected, and leaked secrets. It can be said that behind every success of the old wild boar Pinurhachi, there are one or more spies standing, which is really an incredible thing.

There is reason to believe that Nurhachi had already planted spies before launching each war, and knew the situation of the Ming army through intelligence, so he made targeted arrangements in terms of the timing of the use of troops, the strategy and tactics of the use of troops, and the Ming army was calculated everywhere, passive everywhere, the battle had not yet been fought, and the victory or defeat had already been decided. Nurhachi's spy work is very sophisticated, and most of the details of these behind-the-scenes transactions have been hidden, but there are also some clues, and the truth of the matter can be vaguely seen.

Nurhachi's "fifth column" has done a relatively solid job, and if it is to achieve one thing, it is not necessary for thousands of people to work hard, and if it is necessary to break one thing, only one person is enough, and this is the role of spies. The contribution of a thousand warriors is not worth the damage caused by a single spy, this is the power of espionage warfare! Nurhachi's military successes that year. The "Fifth Column" has made great contributions.

After the death of the old wild boar skin, Huang Taiji was even better than the blue, better than what he Lao Tzu did, and the "fifth column" was active in the countless victories of Jiannu's wars. Now, Huang Taiji is also dead, but Zhou Huchen does not believe that Jiannu will abandon this "tradition". It seems that Dolgon is also very good at using the "fifth column", because the history of the Southern Ming Dynasty shows that many battles have had abnormal collapses or surrenders, and the power of the "fifth column" must be treated with caution.

As a result of Jiannu's southward movement, many people are retreating south. Including the common people, the squires, the officials, and the officers and soldiers who retreated.

Everything is chaotic, especially in the area of Yangzhou, which is easily accessible by water, and is the best place to retreat south of the Yangtze River.

Yu Dahu was under great pressure, because he not only undertook the task of transporting the victims, but also was responsible for transporting weapons, equipment, and food to Yangzhou, and at the same time, Yu Dahu had to closely monitor the long river defense in Yangzhou.

There was a serious shortage of manpower, as did the ships. But Yu Dahu insisted tenaciously, the brothers were very powerful, no one complained about anything, even those who had just joined the Jiang Defense Corps had nothing to complain about. Being able to eat well in this chaos and being able to participate in it makes them feel the value of life.

Yu Dahu leads by example, and his old brothers are almost desperate.

Jiangdu is the water gateway on the east side of Yangzhou, and it is bordered by the Yangtze River in the south. It is adjacent to Yangzhou in the west, and the rivers and lakes are intertwined, and the Tongyang Canal runs through the east and west. The Beijing-Hangzhou Canal runs through the north and south. Due to the smooth flow of waterways, Jiangdu is also the area where Yu Dahu's subordinates have the most frequent activities.

Li Jun is Yu Dahu's elder brother, and he also has the title of a hundred households, and he is the helmsman in the Jiangdu area.

I can't remember how many days I haven't slept well, but Li Jun can't stop his work. There were too many people to go south, men, women and children, officials and gentry, and even defeated soldiers, and the number of people could not be counted.

Li Jun's main responsibility was to divert the stream, and he wanted to separate these people who went south, either by going south down the river, or by letting these people go south by land after landing on Zhenjiang. Li Jun has always adhered to a principle in accordance with Zhou Huchen's instructions, unless his own people or envoys sent by the imperial court to cross the river, the rest who dare to go north will be detained by Li Jun.

This is the liliang of rights, Li Jun suddenly found that he had rights, even if some people were deducted by mistake, but these people only whispered and complained about it. Power is indeed a good thing, and Li Jun was a little surprised to find that Zhou Huchen's liliang was much bigger than he imagined.

After a tiring day, as night fell, there were fewer people going south, leaving some people on duty for the night, Li Jun hurried up and began to rest.

It was the rainy season, and the water in the canal was quietly rising, and a canopy boat quietly approached the river bank from the south in the middle of the night.

In the canal, Li Jun's men were very vigilant, and almost every passing section there would be boats and people patrolling the river and the shore, and the faint lights and figures made the canopy boat stop far away.

The boat docked silently, and then two figures sneaked ashore.

The place where the boat docks is called Huangjiazhuang, Huangjiazhuang is only more than ten miles away from Yangzhou City, due to the weather, the black around is not seen five fingers, the direction of two people touching the black is the northwest, which is the direction of Yangzhou. The defense of the Yangzhou Canal was too tight, and these two people seemed to have come with a purpose, and chose the secluded place of Huangjiazhuang to enter Yangzhou.

The road was full of rice paddies, and the paths along the side of these rice fields became very muddy due to the rain, and the two people kept bypassing the paddy fields with great difficulty in the dark.

An hour passed, and at last I saw a relatively narrow canal dividing channel ahead.

The two of them hugged together and muttered quietly, and then continued a short distance away from the canal divide.

There was a "pop", and suddenly there was a soft sound on the left.

Quickly stopped, and the two did not dare to move. Soon, there was a fluttering sound in the night, as if a bird had flown up.

As the sound of birds flying faded away, there was silence all around. The two of them were very cautious, and did not move immediately, but stood quietly in place and continued to listen to the movement.

After a while, there was no sound around, and the two finally moved again. Slowly and cautiously moving forward for a short distance, the two men whispered again.

Suddenly, the two of them felt a strange noise, and then the wind sounded, and the wind was still very strong.

The screams followed, followed by shouts and footsteps.

In the midst of the chaos, a little spark appeared in the night, followed by the sound of blowing the flame, and then two pines were ignited.

Ten strong men appeared in the light of the fire, and seven or eight big men threw themselves on the muddy ground, and they held down the two people who had sneaked in.

"Tie it up, don't let them run away!" A large man with a torch in his left hand and a sheathed sword in his right hand was obviously the leader, and after saying that, he came closer.

One of the people who was crushed to the ground was still struggling, while the other was silent.

The struggling man was quickly subdued, and several strong men quickly tied him up tightly, and then gagged him with a rag. The leader crouched down, and he began to observe the other infiltrator, who was lying on the ground motionless with his face covered in blood.

The big man at the head stretched out his hand to test the snort of this person, and then said: "It's really corrected, fainted!" ”

"Dare to come to our territory that we don't harvest at night, and look for death!" Another large man with a torch stepped forward, and he lifted the motionless infiltrator and turned him over.

"Let the brothers in the back send them back to the city and hand them over to the young marshal's subordinates to deal with, and the rest will continue to be on duty for the night." The leader of the big man stood up.

The vicinity of Yangzhou is indeed a place where the night is not harvested, especially at night, these battle-hardened and experienced night harvests are definitely the kings in the dark. The work assigned to them by Zhou Huchen is a bit reversed day and night, that is, they sleep a lot during the day and scatter at night.

Two infiltrators are taken away, the firelight is gone, and these fierce night masters disappear into the darkness (to be continued......
