The tide of enemy troops, with cavalry in front and infantry behind, slammed into the shield wall on the causeway, stirring up a flurry of earth and rocks. Under the stabbing of the gun, it receded like a tide.

Sharp arrows burst from the tower into the enemy's ranks, scattering patches of flesh and blood.

Behind the causeway, trebuchets threw oil bombs wrapped in cowhides, which exploded when they landed in the enemy's formation, burning the enemy's skin and flesh, and screaming incessantly.

However, the enemy had also made rudimentary catapults, and huge stones were thrown down to the rear of the causeway, and once the protection of the formation was neglected, the powerful impact force smashed the arrow tower to the ground, and the soldiers on it were killed and wounded by the stones.

It was already night.

Just as the soldiers of the Five Peaks were about to take a breather, the ground suddenly shook.

With a bang, many dirt surfaces exploded, and then groups of soldiers armed with broadswords broke through the ground!

Unexpectedly, many Wufeng sergeants who looked lazy roared one after another, forming a battle formation as quickly as possible, without any confusion.

They surrounded them from all sides, stabbing the enemy from the tunnels with their spears.

The attacking coalition soldiers were hit hard as soon as they appeared, suffering heavy casualties and had to retreat through the tunnels.

Su Xiyan stepped over and said, "Block the tunnel with soil and stones, but you still must not relax your guard." ”

"Not only can you count the enemy army to rob the camp in the tunnel, but you can also count where you came from, and the military advisor is really a god. A junior leader looked at him admiringly.

Su Xiyan said: "It's nothing more than a careful analysis when surveying the leylines, carefully analyzing, and calculating the path and location of the enemy's possible sneak attack." If the enemy army cannot be attacked for a long time, it will naturally adopt an authentic strategy. Astronomy and geography, yin and yang mathematics, there is a set of truths, as long as you learn it thoroughly, many things seem complicated. It's actually very simple. ”

He said it easily and freely, but Wu Feng knew that Su Xiyan must have begun to study various knowledge when other children were playing all day, and he had studied hard to be so knowledgeable and almost omnipotent.

This defense system is deceptively simple. However, Su Xiyan's dispatch made an ordinary earthen embankment more difficult to attack than Jintang Iron Wall. The coalition forces are four times larger than their own, and they have not been able to break through the slightest in these twenty days.

The opponent is not ignorant of soldiers, and the timing of the charge is often very accurate, and he also knows that the weak soldiers will carry dirt bags and fill in the trenches while they are in chaos. And organize the coalition forces to charge in turns, which not only preserves the physical strength of all the soldiers, but also prevents any force from losing too much loss and losing the belief in victory.

There are also a number of sheep intestine trails on both sides of the Returning Wind Valley that can accommodate one or several people to walk. Although it is extremely difficult and difficult to walk, it can be used for sneak attacks. However, Su Xiyan arranged ranger patrols at key positions, set up sentry lookouts at high places, and worked day and night, so that the enemy had no way to take advantage of it, and he also tried to attack the rear of Huifeng Valley with a small force, but returned several times.

Whenever the coalition army was tired and resting, Su Xiyan ordered the people to clean the trench overnight. Widen it again as much as possible to withstand the next wave of attacks.

The frequency of attacks by the coalition forces is not too high. After all, it is not the Goshawk Department's own men and horses, and the heavy casualties in a short period of time are not something that the various forces in Monan can bear.

Su Xiyan also knew the truth that if he defended for a long time, he would lose it, and from time to time took advantage of the gap between the enemy's attacks to harass and sneak attack with small troops, and achieved certain results to boost his morale.

The bodies of the deceased were also buried on the spot as soon as possible. In order to avoid the plague in the middle of summer, the wounded were sent to the back village, where they were rescued by doctors, and there was enough medicine in the back village to ensure that the wounded could recover their combat strength as soon as possible.

"Dead rabbit. Have you been on the battlefield before?" Wu Feng asked. Looking at Su Xiyan's skillful performance, you can know that he is experienced, and he must have seen a big battle.

Su Xiyan nodded.

"When?"

"Three years ago. Su Xiyan said.

Wu Feng secretly thought: He also went into battle for the first time when he was thirteen years ago three years ago, and with Deng Aihou attacking Deng Rong, but the basic knowledge of military science was far less solid than Su Xiyan. Presumably, this dead rabbit has been guided by a master since he was a child.

Outside the Wind Valley, under the Wangcheng Peak.

Several soldiers were sent to the camp of the Three Lacking Daoists.

"Spare your life...... the men said in a loud voice.

The three missing Daoists asked, "Are you waiting to come down to draw water?"

Several people hurriedly said: "Yes, yes......"

On one side, the Three Lack Daoist disciples of the Nine Tribulations Dao said: "No wonder the five hundred people on that peak have been surrounded by us for twenty days, and there is no lack of water......

Wangcheng Peak is dangerous, but there is no water source. The Three Missing Dao people have been holding over this small army with 4,000 people, and only occasionally lead people to participate in the impact on the main force of the Wufeng Army.

He also attacked several times, and found that it was indeed difficult to fight, the mountain was too dangerous, and the losses were not small, so he adopted the method of besieging but not attacking, intending to kill all Li Xun's troops to death.

It turned out that after all this time, the 500 people were still alive.

The three missing people said: "Where are you going to draw water, and tell it, and I will spare you from death." ”

Several captured water collectors said: "There is a small road behind Wangcheng Peak, which is more rugged and difficult to travel than the front mountain, but it leads to Xixi a few miles away, which can draw water. ”

The three lack of Taoism said: "Let people go to investigate, but if it is as they say, spare them from death." ”

A scout took the order and went away, and soon returned, telling him that this was indeed the case, and that with the castration of these people, they were indeed heading to Xixi.

The Three Missing Daoists looked at the disciple Nine Tribulation Daoists: "What do you think?"

The Nine Tribulations Daoist is actually only a few years younger than the Three Lack Daoists, but he is his disciple, this person is extremely tall and muscular, not like a cultivator, but like a murderous bandit.

"Attack from the side path and kill the enemy without leaving a chicken dog behind!" said the Nine Tribulation Daoist viciously.

The scout said: "The path is long and dangerous, winding and twisting, it is good to take it down from above, if a large number of troops go up from below, they will definitely be discovered by the enemy, and they will not spread out on the mountainside, and they will be attacked by people from a high position, and I am afraid that they will suffer greatly." ”

Sanwu Daodao: "In this case, let people guard Xixi, so that the enemy can't draw water." ”

The Nine Tribulations Dao said: "The disciple is willing to go." ”

The three missing Daoists nodded: "You select five hundred people from the people and horses of the Immortal Daoist Temple, and then draw five hundred people from the soldiers and horses of the small forces." Thousands of men guarded Xixi, and if any stragglers came down to draw water, they were captured. If the enemy army is killed in large numbers, it will be wiped out!"

The Nine Tribulations Daoist raised his voice and said, "Command!"

On the peak.

Li Xun flew up a higher mountain and looked into the distance. Then he flew back and said leisurely: "The enemy really sent troops to guard Xixi." ”

He looked at Shi Shuzheng: "Senior brother, do you know my next step?"

Shi Shuzheng said: "Send a few more people over to draw water, and deliberately get caught." ”

Li Xun smiled smugly and walked towards the cliff behind the peak of Wangcheng Peak.

He seemed to pass through the cliff and disappeared without a trace.

However, there is actually a very hidden cave here, because the mountain wall is sinking. If you don't look closely, you can't see it at all.

In the middle of summer, it often rains on the grasslands, but the grasslands belong to the hinterland of the continent, and the amount of precipitation is limited.

However, when it rains, the rainwater collects through the cracks in the rocks in the mountain and then flows into the caves, forming a spring of water.

In addition, the Mikawa Sword Sect has a secret method of condensing water from the air. Li Xun and Shi Shuzheng can produce a certain amount of water every day, which is enough for the whole army to drink.

This is the key to why Li Xun must choose Wangcheng Peak and why there must be only five hundred people. If there are more people, there will not be enough water to drink.

Li Xun looked at several soldiers who were collecting water with buckets, and smiled warmly, making several people feel warm in their hearts.

But his eyes had already seen the scene of a mountain of corpses and a sea of blood.

Unlike before, he was excited about it this time.

Not only excited because the strategy is about to succeed, but also excited because the person is about to kill happily.

As Wu Feng said. His cold blood began to heat up, and he truly lived for himself. Rather than being tied to the family's mission.

West Creek.

The Nine Tribulations didn't know that they were on a death mission.

The past few days guarding Xixi have been really idle, and the idleness has made him lazy.

Since the soldiers who came to draw water a few days ago were arrested again, no one on the mountain dared to come down to draw water.

There has only been a light rain in the past few days, and it is impossible to drink it for 500 people on the mountain. The area on the top of the mountain is limited, and even if it is covered with pots and pans, there is not much water.

His men were similarly lazy, believing that they were far removed from the bloody battlefield.

The only thing you need to guard against is being attacked. However, Li Xunbu has been watched by the three lack of Daoist people, and there are only five hundred people in total on the peak, how many people can be divided?

A few miles down from the mountain here, how much more vigor can two or three hundred people have? There are a thousand people here.

What's more, when they captured it, they were probably too thirsty to stand it. Combat effectiveness must be limited.

That's what everybody thinks.

At night, the male soldiers and the female soldiers even openly mingled in the camp tents. Some people even went out to raid the margins of some small tribes, and captured the lone shepherdess into the camp for sexual pleasure.

Li Xun didn't have to guess to know that such a situation would happen.

He did reduce the water rations for the soldiers, and made some of them pretend to be listless, creating the illusion of a lack of water.

The horses that were brought up the mountain were slaughtered, leading the enemy to think that they had begun to quench their thirst with horse blood.

This situation became more and more confusing to the enemy army.

On a dark and windy night, a small flying sword swept out silently.

Several careless sentries were simply cut by flying swords on the high post, and their vocal cords were also severed, and they fell without making a sound.

The two hundred soldiers led by Li Xun climbed the mound, and from then on, they could see the camp of the Nine Tribulation Daoists clearly.

At night, there are still wind lanterns illuminating, and the sound of ** is still low in many camps.

"What a rabble. Shi Shuzheng gathered the sound into a bundle and passed it into Li Xun's ears.

Ordinary soldiers bite small sticks in their mouths and are not allowed to make a sound.

"The grassland is originally a group of soil buns, and the people sent out to guard the stream are all weak soldiers...... Li Xun replied calmly, and it was also directly passed into Shi Shuzheng's ears, so that others would not hear it.

The two hundred men he brought down all had the strength of soldiers.

In this battle, the outcome has been decided. (To be continued......)
