If you don't eat, you will be hungry, if you don't drink water, you will be thirsty, eating and drinking water is something that everyone has to do every day, and if you don't eat and drink, it will affect your normal life, which is the same for anyone.

And for the Nurhachi tribes, who were marching rapidly, the need for water seemed to be a little greater than food.

Eating a full meal can last four or five hours without being hungry, drinking water and drinking enough can not last four or five hours without thirst, and sometimes a charge and a run will make your mouth dry and you must drink water.

Mao Wenlong knew that grain could be stored in large quantities, and Nurhachi would definitely scavenge a large amount of grain to store grain, but water was obtained on the spot, and Nurhachi couldn't think of so much, especially the deliberate storage of water, he couldn't think of it at all.

It is extremely difficult to burn grain and grass, but it is not so difficult to poison water.

Mao Wenlong sent people to collect intelligence for a period of time to understand Nurhachi's marching route, compared with the route of Xiao Ruxun's army to the south, so he quickly determined that Nurhachi would continue to follow Xiao Ruxun's route to the south.

He will not be stupid enough to use 2,000 people to fight hard with Nurhachi's nearly 5,000 soldiers and horses, and he can't row the boat if he capsizes in the gutter, and the North Koreans' weakening of Nurhachi is very limited, and Mao Wenlong himself must take action, so poisoning is an act of paying less and getting a big return, of course, the risk is also extremely high.

However, poisoning water will bring a double blow to the Jianzhou soldiers, both physically and psychologically, so that they dare not drink water at will and take water at will.

The more you wait, the more thirsty you get, the slower your march becomes, the more unstable your morale is, and the more exhausted your physical strength becomes.

Their emotions will also be on the verge of collapse because of this kind of thing, and when the time comes, they will not even need a large army to attack to achieve victory, or they will win on their own.

This is a great credit, and it should be able to meet his needs.

As for the North Koreans...... He was so disappointed.

A group of outlaws who were beaten by Daqin were able to break through Pyongyang, one of the three capitals of North Korea.

After all, it was an army of 200,000 and there were siege equipment, but what did Nurhachi have?

With less than 5,000 remnants and a group of oil bottle troops, he did not have heavy siege weapons, and he would not carry them, so as long as the city was closed and defended, he could keep the city and drive Nurhachi away, but he was actually breached.

Not only that, but the city was slaughtered, burned, looted, not to mention, the city is gone, what do you say these Koreans are doing?

The soldiers under his command were dumbfounded, and they couldn't figure out how the wandering Jianzhou soldiers could break through such a city.

Mao Wenlong couldn't figure it out, and he couldn't answer the soldiers' doubts.

But there is no doubt that the tragic situation in Pyongyang and the corpses made him think more carefully about how to deal with Nurhachi.

On the other hand, Nurhachi's life is not easy, since the death of more than 300 people who drank water poisoning, his control over water sources is quite strict, specially caught some animals to test poison, only those that are not poisonous are allowed to drink, and those that are poisonous are not allowed to drink, not only wells, but even some small streams are treated like this.

In this way, although no one will be poisoned to death, it will greatly slow down the speed of the march, and the soldiers' thirst and desire to drink water will be greatly aggravated, and the army's morale will begin to be unstable.

Nurhachi gritted his teeth and hated those who poisoned the water, he thought that it was the behavior of some North Koreans, in order to retaliate against him, so that his army did not dare to drink water, and now he had to start trying to find a way to store water, and some containers that could be used to hold water were used to hold clean water.

For the sake of water, the speed of the march was greatly slowed down, and it was supposed to be able to attack Kaesong in a few days, but now it is full of grinding on the road, looking for reliable water sources to supplement their needs, and even the raids are a little inadequate, and the morale begins to decline, and it is no longer the madness it used to be.

Nurhachi began to panic, even in the limit state of the brain did not know how to deal with the problem of drinking water, he always had to drink water, he could not drink water.

At this time, the news of the approach of the Qin army came from the rear, and their rear troops were about a day's distance from Nurhachi's location.

On October 17, the sentinel cavalry of the rear unit of the Jianzhou Bingdian encountered a small group of forward sentinels of the Qin army, and the two sides fought, and the Qin army's sentinel cavalry retreated after killing three Jianzhou soldiers, and did not fall in love, but seemed to go back to report the news.

This news immediately alerted Nurhachi and immediately ordered him to speed up the march and turn to Chungju in the southeast direction through Kaesong as soon as possible.

He knew what it meant to keep going on like this, he knew it very well, but he knew that if he didn't go on like this, he would die faster.

As he accelerated his march, the lack of water affected his troops even more, and he ordered that water be given priority to the soldiers, and that the rest of the men would only be given a small amount of water, but they would have to move with the soldiers, which made their movement even more sluggish.

Despite their desperate search for a reliable source of water, Nurhachi and Fei Yingdong came to realize that the tens of thousands of people had become a liability.

Especially after arriving in the Kaesong area and encountering resistance from the North Korean army.

On the afternoon of the 17th, Nurhachi and others finally arrived in the Kaesong area, where they encountered stubborn resistance from the North Korean army.

The North Korean army set up a large number of roadblocks and traps here to prevent Nurhachi and others from advancing, and even used the tactics of clearing the wilderness with strong walls, so that all the villages and towns in the entire Kaesong area could not find a single living person or grain, and the wells were blocked with stones or defiled with animal carcasses, making them undrinkable.

There is no doubt that this was the handiwork of Yoo Chenglong, and after he arrived in Kaesong, he was supported by the whole of Kaesong, so he fully mobilized the people and troops, and implemented the tactics of fortifying the walls and clearing the wilderness, so that the Jianju soldiers could not get any supplies.

He didn't think of poisoning the well, but the effect of using animal carcasses to filth and throwing stones to fill the well was the same, both of which left the Jianzhou soldiers without water to drink.

In a sense of predicament, Nurhachi ordered the soldiers to dismantle the barrier and to find a reliable source of water, which, in his opinion, was drinkable and needed to be removed immediately.

However, the clumsy Jianzhou soldiers thought about it for a long time and didn't know what to do, so they could only use manpower to slowly carry the stones, and there was no other way.

There was no water on this side, traps and barricades on the other side, and people were constantly being injured and killed, which annoyed Nurhachi.

What was even more annoying was that there were elusive Korean soldiers armed with bows and crossbows to fight guerrillas, which caused great trouble to the soldiers who were dealing with traps and roadblocks.

Nurhachi was trapped less than ten miles from the city of Kaesong, unable to move.
