The war in Fengzhou has entered the twelfth day, and within 12 days, the Turkic army launched a total of four large-scale attacks, but all four attacks failed miserably, the Turkic army has suffered as many as 40,000 casualties, and the defenders of Dali City have more than 6,000 casualties, and the war has gradually entered the white heat.

The wilderness was full of corpses, full of stumps and broken arms, blood stained the land outside the city of Dali, hundreds of nest carts, ladders collapsed in the wilderness, they were like warriors who died in battle, desperately looking at the red flag of Dasui that was still fluttering on the head of the city of Dali.

The tactics of the Turkic army are also constantly changing, the sky is not yet dawn, and the inside and outside of Dali City are shrouded in a thick white fog, which is the weather that often occurs in the mid-spring season, and the wind and sand in autumn are the same as the characteristics of Toyoshu, but the fog will not last long, and it will dissipate after dawn.

The battle had stopped for a day, and the eight thousand defenders of the city, in sheepskin and thick blankets, were curled up by the wall and asleep, when a violent tremor woke the soldiers from their dreams, and the alarm bell on the city sounded, 'Dang! While! While! The screeching of the bell woke up all the soldiers, and the militia soldiers who were resting under the city quickly rushed to the top of the city and entered their combat positions.

A milky fog filled the city walls and beyond, and nothing could be seen from dozens of paces, only the rumbling sound was heard, and the soldiers were talking, but everyone's hearts were full of doubts and vigilance.

If the enemy is attacking the city, why is there no drumbeat for the attack? They fought the Turks countless times, and an attack without the sound of drums never took place.

In the fog, the flag on the conning tower was useless, and it could only rely on the herald, and the defender of the city would ride a horse and Yang Sien galloped on horseback. He shouted: "This is a sneak attack by enemy troops, a trebuchet launch!" ”

In the sound of commands. One after another trebuchets began to creak and wrhim, and the long arms bounced violently, shooting out the boulders and into the vast mist, and in an instant, a scream came from the mist, and there were really enemy troops. The soldiers of the Sui army cheered up their spirits, drew their bows and released arrows, and a rain of arrows shot out of the city, and almost at the same time, the overwhelming arrows flew out of the fog, and dozens of Sui soldiers were caught off guard. Screaming and being shot down.

In a whistling sound. Hundreds of boulders also flew from under the city, 'Boom! The ground smashed on the top of the city, and a huge stone shattered the battlements, smashing more than a dozen Sui soldiers into the air, and another boulder hit a trebuchet, which fell apart with a bang, and a huge log smashed on the top of the Sui army. The screams kept rang out.

The fog turned the tide of the battle, and the besieging side, which had been in an unfavorable position, began to gain the upper hand, and instead of beating drums and blowing trumpets, the Turkic army launched a silent sneak attack. Two hundred trebuchets were put into the battlefield, the Turkic army's trebuchets were smaller than those of the Sui army, and they belonged to the human-pulled launch, and a trebuchet needed hundreds of people to pull, and the range could reach 250 steps. Under the cover of the fog, they had reached two hundred paces away. A fierce attack was launched on the city of Dali.

After more than ten days of fierce fighting, the Turkic army gradually discovered some defensive loopholes of the Sui army. Most of the Sui army's trebuchets shoot at a distance of about 400 steps, and the shortest is 300 steps, while the distance of the stone cannon is no more than 100 steps, so between 100 steps and 300 steps, there is a gap, and a crossbow arrow can be used to make up for it outside a hundred steps, but between 200 and 300 steps is the weakest link in the Sui army's strike force.

In this defense link the Sui army is to use the bed crossbow, but the destructive ability of the bed crossbow can not be compared with the trebuchet after all, and the Turkic army used the Doumeng defense, the so-called Doumeng is actually a large leather shield, the appearance is like a bucket and got the name, a Doumeng is one zhang two feet high, up to two zhang wide, with a giant wood as a support, covered with dozens of layers of cooked cowhide, in addition to the impact of a thousand catties of boulders can smash the bracket, and the bed crossbow and stone cannon can not penetrate it, this is the invention of more than a dozen craftsmen who fled to the Turkic Mayi County, and the crossbow arrows of the defense Sui army are very practical.

Under the protection of the fog and Doumeng, the bed crossbows of the Sui army lost their power, and the two hundred trebuchets of the Turkic army began to exert their power, and the huge stones smashed heavily on the city wall, breaking the city bricks and denting the walls, and the Sui army and militia soldiers defending the city suffered a large number of casualties in the impact of the boulders, and the trebuchets of the Sui army were constantly hit and destroyed at the head of the city.

Yang Yuanqing has appeared on the head of the city to watch the battle, his eyes are grim, there is a look of worry in his eyes, this is the offensive for more than ten days, the Turkic army used trebuchets to attack the city for the first time, and the use of fog as a cover, no longer use the tactics of the sea of people, the subtle tactical changes of the Turkic army made Yang Yuanqing feel an invisible pressure, he knows very well that this kind of foggy weather will last for at least half a month, which will make it extremely difficult to defend the city.

Yang Yuanqing is not worried about Dali City, he is worried about several other cities, and the defense capabilities of the other cities are not as good as Dali City, can they support it?

The Turks have always been weak in siege capabilities, but this time the Turkic army showed a strong siege ability beyond Yang Yuanqing's expectations, but also completely subverted his concept, five years ago, the Turkic siege weapons are very crude, from the Xue Yantuo siege weapons can be seen, but only a few years, the Turkic manufacturing capacity has improved by leaps and bounds, which can only show that the fleeing Sui people have brought great changes to the Turks, which is also the main reason why every time the Central Plains chaos will give the nomads a chance, not only the Central Plains defense capacity is reducedAt the same time, it also introduces various advanced technologies into the grassland, making the strength of the grassland people stronger.

Yang Yuanqing sighed slightly, the Central Plains people believe in the defense of the national policy can not fundamentally solve the problem, the Xiongnu are gone, the Xianbei and Rouran people come, the Xianbei people go south and the Turks come, the Turks go, there will be the Hui people, the Khitans, the Jurchens, the Mongols, the Manchus, the overlords of the steppe are always endless, and the defense national policy will always be passive.

At this time, a boulder hit a depression in the eastern section of the city wall, and the heavy impact made the city wall unable to hold on any longer, and collapsed violently, revealing a section of collapse more than ten zhang wide and one zhang high, and dozens of Sui soldiers and three bed crossbows guarding here screamed and fell down the city, and a large amount of earth poured out of the city buried them instantly.

At the same time, the Sui army at the head of the city shouted, ten swarthy behemoths appeared in the fog, and the battering rams of the Turkic army appeared, and these giant beasts as high as two zhang and four zhang long were slowly moving towards the city wall.

The battering ram is made of a thousand-year-old giant wood in the Yin Mountain, the head of the mallet is loaded with cast iron, and the iron chain is hung on a huge support, and the roof is installed to defend against bows and arrows, and there are six huge wooden wheels below, which are generally pulled by more than 100 oxen, and after entering the range of bows and arrows, they are pushed by more than 1,000 people.

This kind of battering ram is generally used to hit the city gate, but Dali City has a high suspension bridge, and the city gate is also sealed with a boulder, and there is no point in attacking the city, so the Turkic army uses the ramming of the city wall instead, so that the city wall collapses, so that the Turkic army behind can rush to the city.

The bricks had become loose due to the heavy impact of boulders, and if they were to be hit with battering rams, the walls would have collapsed.

Yang Yuanqing stared at the ten huge battering rams with a stern gaze, he had already arranged a defensive strategy, and waited for the opportunity to appear at that moment.

The moat has dried up, the Turks have laid a thick wide plank on it, so that the huge body of the siege ram can smoothly pass through the moat, the head of the city is like a rain of arrows, more than a thousand Turkic soldiers with a huge shield cover, push the battering ram to continue to advance, and finally withstand the city wall, but the width of the moat to the city wall is only one zhang and five feet, which makes the huge body of the battering ram across the moat.

Yang Sien's eyes were firmly fixed on the ten behemoths, and when they all stepped over the moat one after another, he gave the order, "Ignite!" ”

Hundreds of torches were thrown into the dry moat, and in an instant, the moat fire burned fiercely, the fire was raging, the flames rose, the planks laid on the moat were burned one after another, four or five battering rams fell into the moat, head up, vertical in the ditch, the mallet body fell off, rolled aside, one after another battering rams were quickly engulfed in the fire.

More than 10,000 Turkic soldiers suffered countless casualties, howled and struggled in the fire, and were finally devoured by the fire demons, leaving thousands of people to turn around and run, but forgot to defend themselves, and were shot down by the Sui army's arrows.

In the flames of the sky, the fog gradually dissipated, and the two hundred trebuchets of the Turks withdrew from the battlefield before the fog dissipated.

The sun dispelled the fog, the fire slowly subsided, and the charred corpses of the Turkic soldiers and the remains of ten battering rams were sunk in the moat, curling green smoke and emitting a pungent stench.

The open field appeared in front of the Sui army again, the Turkic army had retreated to the camp, Shibi Khan Duji rode in front of the camp, staring at the city from afar, although he had lost more than 40,000 men in eight days, and the battering ram attack also failed, but the dense fog that appeared in the early morning made him find the opportunity to attack the city, and he began to brew the next large-scale attack in his heart.

At this moment, a cavalryman rushed at a gallop, turned over and dismounted and immediately stepped forward to report: "Qiqi Khan! The third prince has captured Yongfeng City. ”

Daji was overjoyed, and the breakthrough of Yongfeng City meant that his battle of Fengzhou opened a gap, and he immediately ordered: "Order the army to continue south, and be sure to conquer Hekou City!" ”

Du Ji rekindled confidence in his heart, as long as he captured Hekou City, he would open the passage to the south, and he could lead the army to attack Lingwu County, and Yang Yuanqing would have no point in defending Dali City, he would inevitably abandon the city and go south.

The terrain of Toyosu is not as flat as the grasslands, especially in the south, almost all of which are low hills and large forests, of course, there is no problem for the Turkic cavalry, but for a large number of tents, sheepskin rafts, siege engines and other heavy vehicles, they cannot climb over, and can only take the flat gallop roads in Toyoshu.

Dali City is a north-south gallop road, and Yongfeng City is an important town on the north Chi Road, Jiuyuan City is a big city on the South Chi Road, and finally the junction of the north and south Chi Road is Hekou City, you can directly cross the South Yellow River if you take the Hekou City, and then to the south is a horse Pingchuan, directly kill Lingwu County.

Compared with the strong and tall Jiuyuan City, Yongfeng City is much easier to attack, so the Turkic army chose to take the North Chi Road and attack Yongfeng City, and now Yongfeng City has been captured, and there is only one estuary city left.

Du Ji looked at the solid Dali City, and he began to hesitate in his heart, did Yang Yuanqing know that Yongfeng City had been lost?

At this time, his eyes fell on a goshawk flying from the south......
