The outer city of Dali City was built in the fourth year of Daye, it is a long strip of east and west, north and south flat, the north city wall is ten miles long, and the east and west two sections of the city wall are only two miles long, the two ends are tightly pressed against the vault Xuanshi Mountain of Dali City, which builds a hundred steps long plank road at the west side of the mountain, connects the outer city and the middle city, this plank road has been burned down when the Sui army evacuated the outer city.

One of the biggest features of Dali City is that there is no wall road to the upper city in the outer city and the middle city, and it is necessary to go up from the inner city to the city, and then reach the middle city head and the outer city head through the drawbridge and plank road respectively, the advantage of this design is that even if there are spies who pretend to be merchants to sneak into the city, they cannot seize the city gate, and the chain winch that opens the city gate and the suspension bridge are all on the city head.

At night, 40,000 Turkic troops were busy in the outer city, and in the middle city, 10,000 Turkic archers took turns shooting arrows at the inner city...... Idle.

The 30,000 Turkic troops were busy piling up the gentle slopes of the stone road, and hundreds of torches lit up the outside of the middle city wall as if it were day.

Hundreds of miles away is a darkness, dozens of heavy trebuchets stand alone in the darkness like giants, including the huge 40,000 army camp is also in the dark, only hundreds of cavalry patrol back and forth in the camp, and there are only a dozen sentry posts on the outer city wall, after taking the middle city, the outer city wall loses its defensive significance, and the Turkic army no longer attaches importance to it.

At that time, when the Turkic army was busy in the outer city, the end of the east city wall of the outer city had undergone abnormal changes, the plank road was installed in the west city wall, here is a dead road, the end is close to the stone wall of the dome mountain, the dome mountain is a granite mountain, there is no soil, no plants can grow, but the city wall and the mountain stone gap filled in the soil but a few giant vines grow, climb the mountain stone more than a zhang high, the giant vine grows lush, when it is the twilight of spring is when it is luxuriant, almost a mountain stone is covered.

The anomaly happened in the vines, in the night, a hand appeared from the vines and slowly pushed the vines away, a pair of blazing eyes looked outward for a moment, and a Turkic soldier came out of it, to be precise, he was a Sui soldier wearing Turkic iron armor and a hatless hat, which was the dress of the Turkic guards.

Immediately afterwards, a second and a third people came out, and more and more of them numbered as many as fifty people, and they lined up in a neat formation, like a real group of Turkic patrol soldiers, and marched towards the northern city wall.

This is something that the Turks never dreamed of, for more than ten years, the Qionglong Mountain has been dug by the military and civilians of Dali City, which is full of countless caves, and has become the natural wine cellar of Dali City, but these grottoes are not used by the military, and it is impossible that there is a great military secret hidden in it.

That is, a military secret passage was dug in the body of the Dome Mountain, which led directly from the inner city to the outer city wall, and it was covered by vines at the top of the east city, and a false wall was built, which was very well camouflaged, but the plank road was in the west city wall.

This secret passage was dug in the eighth year of the Great Cause, and it has not been used for more than four years, and today it is the first time it has been used.

Fifty 'Turkic sentinels' marched briskly on the head of the city, and in a few moments they came to the northern wall, where there were less than twenty Turkic sentinels on the northern wall, whose duty was to open and close the gates.

In front of a sentry post, three Turkic sentinels were leaning against the city wall and chatting boredly, and the topic was inseparable from the woman and the lamb at home.

"Who is it?" One of the soldiers saw a group of Turkic soldiers coming in the darkness and shouted.

"On the orders of the Khan, I came to check the post!"

The other party's tone was extremely harsh, and the three Turkic sentinels all panicked and stood up straight together.

Fifty 'Turkic soldiers' walked past them, and with a few muffled grunts, the three bodies were dragged away and replaced with new sentry posts, and after only a quarter of an hour, all twenty sentries at the head of the city were killed without a word.

At this time, countless Sui soldiers wearing Turkic army uniforms poured out from the secret passage, about four or five hundred, they were different from the first fifty people, they looked almost the same as the Turks, these were the Tiele people in the Sui army of Fengzhou, a total of five hundred, they were the camel cavalry of Fengzhou, all of them were Qixin people.

They carried barrels of oil up to the city, and found an entrance to the city wall at the east end of the city, and the two of them got into the city wall, and in a moment pushed away a few bricks from under the city root, and drilled out, which was also a secret passage down the city, but not a staircase, but a slide, surrounded by a small forest.

These Tiele Sui soldiers carried the oil barrels to the empty and dark outer city, they put the wooden oil barrels on the ground, and stabbed the wooden barrel plug with their daggers, and the viscous fire oil flowed out of it and flowed all over the ground.

Occasionally, they also encountered inquiries from the Turkic soldiers on the other side of the camp, but their indistinguishable appearance from the Turks made them not encounter any suspicion, and within an hour, they dumped thousands of barrels of fire oil on two high hills, which are blind spots that catapults cannot hit, and where fire oil cannot flow, these two areas can at least squeeze 10,000 people, and Yang Yuanqing will not let a single Turkic army survive.

At the end of the watch, the figure of the Sui army appeared in the empty inner city, thousands of Sui soldiers raised a huge shield and rushed to the city, erected a shield wall, and then five thousand militia soldiers carried the fire oil barrel to the head of the city, these fire oil was collected from the deep well in Yan'an County, it was an important military resource in Fengzhou, in fact, in the period of the Northern and Southern Dynasties, the fire oil was used in the war.

At this time, a hundred heavy trebuchets installed on the inner city wall began to creak and rattle, and in the panic of the Turkic army, one by one the fire oil barrels were thrown out and smashed into the outer city, and more than a dozen huge fireballs that were ignited also rose into the air and shot towards the outer city.

The fire in the outer city spread rapidly, and the 30,000 Turkic soldiers who were piling up the gentle slope were in a mess and fled in the direction of the large camp to the north, but a fierce fire also burned in front of them, and then the large camp in the outer city also began to burn, and the flames rose to the sky and thick smoke billowed out.

The fire grew bigger and bigger, and even the walls of the middle city began to burn, and 10,000 Turkic archers screamed in the fire and fled for their lives, but what awaited them was either to fall to their deaths or to be engulfed in the flames.

Yang Yuanqing stood on the lookout platform on the top of the dome mountain, silently watching the outer city gradually engulfed by the fire, and in the winter-long preparations, he had stockpiled tens of thousands of barrels of fire oil, just waiting for this moment.

The air was filled with a pungent scorching stench and billowing smoke, the outer city gate was closed, the 40,000 Turkic troops in the outer city had no way to escape, the fire spread, engulfing groups of desperate Turkic soldiers The terrible screams resounded throughout the outer city, at this time, Yang Yuanqing's eyes did not have a trace of pity, only endless coldness......

Six thousand Sui soldiers appeared at the head of the outer city, they were lying on the battlements, holding a crossbow in one hand, covering their mouths and noses with a soaked linen cloth in the other.

In the wilderness outside the city, tens of thousands of Turkic soldiers rushed to the city, they wanted to seize the city, open the city gate, and let the soldiers in the city escape, but they were greeted by dense arrows like raindrops, and a large number of Turkic soldiers fell, and the screams and flames in the city made them chill and heartbreaking, and their fighting spirit was completely lost, and they turned around and fled after being ambushed by the Sui army, rushing up again and again, and being repelled by crossbow arrows again and again.

The Turkic Khan stood in front of the camp gate in a daze, looking at the tongue of fire rising in the sky three miles away, his eyes were full of despair, in fact, he thought of the possibility of the Sui army attacking with fire, so he did not allow the soldiers to enter the middle city, but he never dreamed that the fire burning by the Sui army could engulf the entire outer city.

"Khan! Unable to kill them, thousands of Sui troops appeared out of nowhere and blocked us with arrows. ”

Knowing that his army of 40,000 was over, a heart-rending pain was so unbearable that he fainted to the ground.

"Khan! Khan! "There was a mess in front of the camp.

The sky was getting brighter, but the pungent smell of burnt paste in the air had not dissipated, and the whole outer city was still curling with green smoke.

A group of Sui soldiers came out of the secret passage, and the situation in front of them made many soldiers turn their backs in horror, not daring to take another look, what kind of hell on earth it was, all 40,000 Turkic soldiers were burned to death in the outer city, and the entire outer city was dark.

More than 10,000 of them were not burned by the fire, they were huddled in a narrow open space about 200 paces wide between the fire and the tent, and the oil did not flow, but they all died equally, and more than 10,000 people were either roasted alive by the fire, but most of them were suffocated.

As Yang Yuanqing said before the war, he wanted to make the Turks forget the brutal killing of the Battle of Fengzhou for generations.

The cruelty of war lies in the fact that there is no mercy on the battlefield, and any mercy to the enemy is a crime against oneself, whether it is the Turkic army or the Sui army, they all use the most cruel methods to kill each other and completely destroy the enemy physically.

On the same day that the city of Dali was finally burned, the battle in Kawaguchi City was also at its last moment.

Ten miles north of Hekou City, the battle of 30,000 Sui cavalry and 4,000 Mo sword troops against nearly 50,000 Turkic cavalry began.

Li Jing led 14,000 reinforcements from Lingwu County, and cooperated with the 20,000 Sui troops in the city, a total of 34,000 people, under the command of Sima Li Jing of Fengzhou.

He uncharacteristically took the 4,000 Mo Sword Army as the vanguard, set up a large array of Liuhe, and the 30,000 cavalry were divided into six teams, cooperating with each other to attack the enemy from six directions.

In the wilderness, the war horses galloped, 50,000 Turkic cavalry covered the sky and the sun, swept towards the 4,000 Modao Sui army, the 10,000 Sui cavalry guarding on both sides of the Modao array arrows rained down, dense arrows were intertwined into an arrow net in the air, a piece of Turkic cavalry was shot down, and the men and horses fell down in the gallop, and the horses ran past the fallen soldiers, and the horses stepped into flesh, but the 50,000 cavalry were still powerful, like a raging wave to the Sui army Modao army.

"100 steps...... Fifty steps...... Thirty steps...... Twenty steps ......"

Tens of thousands of Turks finally killed the pigtails, they have great confidence in themselves, to use the strength of ten thousand jun to crush the Sui army heavy infantry, the four thousand Mo sword army is lined up in four rows, of which one thousand recruits are in the third row, and the remaining three thousand people have experience in fighting with the Turkic army.

When the enemy army has fifty paces, they quickly approached, four thousand heavy armor soldiers close to each other, at the moment when the enemy army hit like a raging wave, the Mo knife army put the tail of the long knife shaft to the ground, leaned forward, half kneeling on the ground, so that the Mo knife and the ground into an oblique angle, four thousand Mo knives like a semi-lodging forest, densely stabbed at each other, and the other end was dead on the ground, they used the power of the earth to resist the most powerful first wave of the Turkic cavalry.

Thousands of war horses neighed, long blades pierced into their bodies, many war horses were pierced by the Mo knife, but the Mo knife was extremely hard, and it did not break, which is why the Mo knife was required to have the maximum hardness, they must be able to withstand the powerful impact of the cavalry army, and will not break or bend.

As the first wave of impact disappeared, the war drums rumbled, and the first row of Qianmo swords swept the ground and waved the Mo swords, like a wall column, and then the second row of soldiers stood up, also like a wall, the third row and the fourth row advanced in turn, one person in front fell, and the person behind made up.

They cooperated with tacit understanding, with collective strength to resist the impact of the Turkic cavalry, and wiped the knife to kill, cut off the horse's head, cut off the soldier's body, under their pace, the corpses piled up, the blood flowed like a river, killing the Turkic cavalry on their backs, heavy casualties, at this time Li Jing saw that the two wings of the Turkic army were empty, and immediately ordered four Sui cavalry to kill from all sides, with the Modao army as the core, from six directions to attack the Turkic cavalry.

The cavalry fought fiercely, people shouted horses, the Turkic cavalry took thousands of people as a team, with spears, knives, ropes as weapons, under the command of the prince's brother Ashina Xin, and the Sui army fought in Hekou City, this is an elite Turkic cavalry, with cavalry field battle is their indebtedness to both sides of the offensive and defensive order, always maintain a formation, unwilling to easily lose in the hands of the other party, the battle lasted for three days and three nights, the two sides clashed more than ten times, the Sui army killed nearly 10,000 people, and the Modao heavy armor army also suffered more than 1,000 casualties, but the Sui army became more and more courageous, and the Turkic army was tired. It began to be unsupportable.

Although the Turkic army was the overlord of the steppe and had the advantage of troops, in front of the well-trained, well-equipped, and 4,000 heavily armored Mo sword soldiers of the Sui army, this elite Turkic army was finally defeated, and finally collapsed on the whole line after nearly half of the casualties, the Turkic cavalry was defeated, the Sui army pursued and killed all the way, killing 10,000 enemies, and Ashina led the remnants of less than 10,000 troops to flee eastward.

At this point, after nearly a month of defense of Fengzhou, less than 100,000 of the 300,000 Turkic cavalry who attacked Fengzhou were left, with a loss of nearly seventy percent, and 200,000 Turkic soldiers died on the land of Fengzhou.

However, the Sui army of Fengzhou also paid a heavy price, losing more than 50,000 people, of which 42,000 were killed and more than 8,000 were disabled for life, but they did not give in and stubbornly defeated the alien army......
