Huo Yun didn't come to death on impulse. He has a whole set of ideas of his own.

The first step is to bury the knife array. Remove the head of the Mo knife, which is more than three feet long, and the blade is outward, and it is driven into the rock crevice underground, even within the height of a person on the rock wall, but there is a rock crevice, and all the blades are inserted inverted.

There were a dozen paces away, and it was all this kind of sharp blade. Completely block the enemy on the opposite side.

It was almost impossible for those big stone troops to rush over without being killed by the arrows of the Tang soldiers.

Huo Yun, this kid was not polite, and brought more than 20,000 arrows.

In the Wolf Tooth Kendo Fighting Blocking Battle, it is not possible to rely on hand-to-hand combat, and crossbow arrows are the most effective weapons.

Set up the knife array, and the next thing is the arrow tower.

Behind the knife formation, a large shield is used to make a cover, and a total of three rows of shooters can be lined up, with five people in each row. When an arrow is fired, immediately crouch down to load the arrow, leaving space for others.

In addition, twelve or thirteen arrow towers were made in the middle of the canyon.

Take advantage of the gaps in the rock wall, insert a few horses horizontally, lay the shield on the top, tie it firmly, and make it into an aerial arrow tower, which is condescending and very advantageous.

At a time, more than 200 people can be put into the battle, and the rest are responsible for delivering arrows, and once the archers in front and on the arrow tower die, they will be replenished immediately.

Huo Yun, as the commander, stood on the highest arrow tower.

They were busy with their work, and they could hear the sound of horses' hooves rumbling at the other end of the valley.

"Ready-" Huo Yun shouted, and the friends immediately became emotional.

Huo Yun's soldiers are often with him, they are all young people, and he has long heard him talk about the glorious deeds of Huo Shouguang and Zuo Qing, Zhang Jin and others, who wiped out more than 10,000 people in the Wolf Tooth Sword Dao with 2,000 people.

They have always regarded Huo Yun as a hero.

The direction the enemy came from was a flare-shaped canyon, and the closer you went to Huo Yun's side, the narrower it became.

Before they could rush over, they began to regroup, split into two teams and continue to advance.

The boulder rode very fast, and died very quickly.

As soon as the other party rushed within a hundred steps, Huo Yun ordered the arrows to be shot - let them die far away, so as not to pile up too close to the corpses.

The terrain is too unfavorable for the Dashi army, the people in front are dead, and the people behind don't know what is going on.

continued to rush forward, shouting and killing, and the death was endless.

In the blink of an eye, more than 200 Dashi light cavalry and men and horses died together, and the corpses of people and horses were piled up high, blocking the gorge.

The commander in the back hurriedly called a halt.

After a closer look, it turned out that the Tang soldiers had already prepared, and set up an ambush in the Wolf Tooth Sword Dao to shoot their own people.

Continue to organize the charge - first organize people to move the corpses away, and then transport all the corpses and horse corpses back and pile them on the side of the road.

Fought several charges, transported corpses several times.

There was no way to break through Tang Bing's arrow net, and some people finally rushed to the front, only to find that the ground was full of thick blades on the rock wall.

Not only people know it, but horses also know that it is a big blade, and it is very sharp.

Both the people and the horses were frightened, and they quickly turned around - where did they fall over, this section of the gorge is too narrow, and a horse can't cross it - so it turned around urgently, and the horse's head hit the mountain, and it directly hit a ** burst, and the people were thrown out.

Once the fight starts, time seems to pass quickly. After six or seven charges, it was dark. Especially in the canyon, the sun is no longer visible.

The charge was swift, and time was mostly wasted on carrying corpses.

Even Huo Yun didn't expect this before, he was afraid that if the corpses were piled up too much and pressed on the knife array, the knife array would be invalid.

The road in this place is too narrow, and the big stone army must organize a charge while cleaning up the corpses, otherwise not to mention their horses, even they themselves will not be able to run, and they will be living targets when they walk in the corpse pile.

At first, the enemy's brains were still hot, and before it was completely dark, another charge was organized, but it still ended in failure. It was only then that the commander of the Dashi Army came from the rear with an angry "order to retreat".

Huo Yunda grew up in Talas, and he could understand the language of all the ethnic groups on the border, and he knew what the other party was shouting.

The Dashi light cavalry retreated outside the safety line and began to repair and develop a new battle plan.

Huo Yun issued a secret signal, signaling the back army to heat up the dry food and water, and deliver it, everyone changed their guards in order, ate and drank enough, and rested on the spot.

The valley was pitch black, and it was as if people had fallen into an ink vat, and the absolute darkness scared people on both sides.

On those stone walls, and even in the air, there are big cold and powerful hands, and there are sharp knives in their hands, which can cut off your head at any time.

Huo Yun heard a whisper from the other side, and those big stone light cavalry were reminding each other - be careful, don't be touched by the other party and cut your neck.

The people on their own side are the same, they are also afraid of the other party's sneak attack.

Huo Yun passed on the words in code, telling everyone not to be afraid, the ground was full of knives, and the enemy did not dare to touch the dark. Even if they came, they had to light the torches first. The night is good for us, don't be afraid.

Huo Yun's words were verified, and when he first entered the city, the Dashi army began to light torches one after another. This was a precursor to the start of the offensive.

Although the plan for the surprise attack was broken, there was still a large army from the Broken Leaf Okawa in the middle of the night.

They must have been thinking of rushing over, at least in the middle of the night, to form a joint encirclement and onslaught with the main army.

Oishi's soldiers also believe in the Holy Fire Shinrikyo religion, and they have a lot of experience in understanding and mastering "fire".

They did not come with torches themselves, but cut off the heads of the torches and tied them together to make larger fireballs.

They lit the fireball and threw it in the direction of Tang Bing, throwing seven or eight along the way, illuminating the narrow and cramped canyon path.

On the rock walls on both sides of the gorge, some "flames" were also thrown up.

Huo Yun was familiar with their tricks, which were some viscous fire oil mixed in sackcloth, which could stick to rough walls and rock walls, and could stay for about two quarters of an hour. Then it burns or falls to the ground.

The arrangement of these flames is not so worrying, but only to see the road and the people. Huo Yun was more worried about what kind of means they would use to carry out this charge.

Hopefully, you're prepared enough to cope.

The "torches" were arranged, followed by the sound of heavy metal grinding and hitting the ground from the opposite side.

"Oh no," Huo Yun scolded in his heart, "It's a heavy armor soldier." ”

The light riders are all leather armor, and there are plenty of exposed parts on their bodies. The crossbow arrows of the Tang Dynasty, or the archers with good arm strength, can shoot them.

Huo Yun had seen Dashi's heavy armor, and in several battles when Dashi's army invaded the Tang border, Huo Yun also captured several of their heavy armor.

The deck of the heavy armor was thick, completely covered from head to toe and hand to hand, with only the mouth with a thin hole for breathing, and a narrow slit at the eye less than the width of the little finger.

Moreover, the heavy armor they made, the links of various joint parts are very ingenious, which does not affect people to draw the bow and swing the stab.

A heavy armor is 70 catties to more than 100 catties. The heavily armored soldiers were all cavalry, and with the heavily armored war horses that were also tightly wrapped, they were almost invincible when they charged.

Any infantry formation and light cavalry formation, under the charge of heavy cavalry, is like a wild boar entering a vegetable garden.

Listen to the sounds, only the footsteps of the heavy armor. They came on foot.

A few thoughts quickly flashed through Huo Yun's mind, and in the end, they were definitely not here to kill, they were here to pull out the knife array on the ground.

As long as the sword formation is pulled out, they can organize a rapid charge on a single horse, as long as they break through the wolf's tooth sword path, annihilate their reserve troops, and then counterattack the arrow tower, it will be easy.

First of all, two heavily armored soldiers trotted over with heavy hammers.

They didn't care about the arrows that came at them - the crossbow bolts were shot on the thick plate armor, and all of them were bounced off without exception.

"Oil thunder, ignition. ”

Oil thunder is a "firearm" invented by Huo Yun, and it is also a ball made of sticky oil soaked in thorns - however, this messy ball is not so tightly entangled, it is loose, and it will immediately form a puddle when thrown on a person, and it will stick for a long time.

This is a "firearm" created by Huo Yun specifically to deal with the heavy armored cavalry.

The crossbowmen of the Tang soldiers in the arrow tower hurriedly took out a "iron fence", this iron fence is the iron fence that really cooks dumplings and noodles.

Hold the oil thunderbolt with an iron fence, light it, and throw it on the throwing party.

If you do it directly by hand, you will burn yourself severely.

Four or five oil thunderbolts stuck to the opponent's heavy armor, but they couldn't kill them quickly. The two big iron guys rushed over, and against the blazing fire on their bodies, they began to hammer and hammer the Mo knives stuck in the rock wall and the ground.

Datang's Mo knife was very thick and deep, and it took more than a dozen times before a Mo knife was smashed loose.

They continue to smash.

"Be careful not to waste oil thunderbolts, throw them at your head—" Huo Yun reminded in a low voice.

The oil thunderbolt was thrown on the other side, and it was already on fire. Huo Yun simply threw a large ball of hemp, soaked in fire oil, and threw it over without igniting it. In order to allow the fire oil to penetrate the cracks of the opponent's plate armor.

The flames ignited the freshly poured oil, and at last roasted them to a pulp.

They pounced on each other for a while, trying to put out the oil mines, but they were all over their hands and arms.

The flame has been burning for a long time, and the iron plate is hot. There was also a heavy armored soldier with an oil thunderbolt in his neck, and the burn was even worse.

These two iron guys couldn't bear it anymore, and finally ran back screaming.

The one with the burning in his neck was burned to death halfway through.

These heavy armors are also flawed - they are difficult to take off on their own, and someone has to help them. Once burned, it is fatal.

Several enemies surrounded him, trying to help the escaped heavy armor dismantle the burning iron armor. But he burned so badly that he rolled on the ground in pain, and the helpers couldn't do anything at all.

The little water in the water bladder was splashed on it, but it was useless, and it was impossible to douse the fire caused by fire oil.

The attack of the first group of heavy armor was repulsed. However, it still poses a great threat to the Tang Soldier Sword Formation, and the enemy also recognizes that this is the most effective way to dismantle the Tang Soldier Sword Formation and break through the Wolf Tooth Sword Path.

Soon they organized a second round of attacks.

This time it was four heavily armored soldiers. Two heavily armored soldiers were responsible for beating the Mo knife on the ground, and the other two held shields to block the oil thunder dropped by Tang Bing for them.

The oil thunder couldn't be thrown on the other party, so he could only watch as people hammered the Mo knife on the ground and on the rock wall.
