"Qi Yu general system, the direction of the sandbank is urgent, Cao Rengui's 100,000 soldiers and horses attacked on all fronts early this morning to besiege the sandbank city, the situation on the sandbank is urgent, Minister Wang ordered our army to move out as quickly as possible and gallop to the aid of the sandbank." As soon as the Modao battalion arrived outside Suoyang City, the Red Feather messenger on the other side of the sandbar met Shi Jian unexpectedly.

"Commander of the guard, blow the trumpet of the charge, and order the whole army to assault Sandbank City." Shi Jian knew that Wang Houchun would not directly order himself to be pulled out quickly until he was in a critical situation, this should be because Cao Rengui had already learned about the big battle on the Yizhou front from some channel, so he would be desperate to take the sandbar and cut off the back road of the main force of the Western Expeditionary Army, so as to reverse the unfavorable situation of the Yizhou front. Therefore, Shi Jian was anxious at this time, and desperately began to blow the trumpet of the charge during the march, so that the whole army could increase the speed to the extreme.

The distance from Suoyang City to Shazhou City is more than a hundred miles, the Modao Battalion is a famous heavy unit of the Tiance Army before the change, so the marching speed is not his forte, although the heavy armor is removed after the change, but the Modao Battalion itself is a tall and sturdy man, so compared to the third battalion, this kind of light and flexible warrior does not have an advantage, fortunately, the physical strength is okay, and the forced march will at least not make them lose their combat power.

The Modao battalion received an order to advance in a surprise attack, and was also quickly transmitted back to Shazhou City by the Red Feather messenger. At this time, fierce battles were taking place on all sides of the sandbank, and Li San'er and his men did not improve the situation of defending the city after returning to the city, because Cao Rengui's side began to attack from all sides after getting the general information of the battle of Yizhou, and they did not stop for a moment. Although there were more than 10,000 defenders in the city at this time, plus Qingzhuang, the troops were diluted after being scattered on the four city walls, and after the other party went all out, the mechanical crossbow controlled by Wang Houchun was divided into four parts, and the division was on the urn city wall of the four city walls, constantly firing at a rapid pace, and supporting the increasingly critical battle with strong firepower.

"Go, inform Yang Yi, let him lead the team to Xicheng to defend on the spot, no matter what, don't let the Guiyi army climb the city wall, and throw incendiary bombs when necessary." Wang Houchun asked the captain of the personal guard behind him to immediately set off to find Yang Yi and ask him to lead the team to the west city wall, where the battle was fiercest, to supervise the battle on the spot. Now in the city, Wang Houchun controls the mechanical crossbow to support remotely, and commands in the south city nearby, Li San'er leads the team to meet the enemy in the north city, and Tuoba Siji is also in the east city. In this way, the four city walls maintain a commander-in-chief in the vicinity, and it is convenient to stabilize the morale of the army at critical moments and maintain the basic battlefield balance.

And in Shazhou City, which is in great danger, there are constantly soldiers of the Guiyi Army who have gone forward and followed each other under the orders of the rear general to cross the battlefield that has been full of corpses, climb the bloody ladder and climb desperately under the cover of all kinds of siege weapons, and the Tiance Army on the city tower relies on artillery and bed crossbows in the rear to launch a counterattack, a group of soldiers either hide behind the female wall and shoot at the dense Guiyi soldiers under the city, or carry all the shells and explosives bags in the warehouse onto the city wall, Then he lit the fire and threw it down, and the powerful explosion scattered and flew with the severed arms and limbs around it, tearing the Guiyi soldiers gathered under the city wall to pieces.

"Commander, the Minister orders the Molotov cocktail to be dropped." The captain of the personal guard finally passed through the city wall where people came and went, and he also encountered several Guiyi troops who rushed up to the city wall in the middle, fortunately, the Tiance army responded in time, and the reserve team quickly stepped forward to strangle all these signs after the other party broke through the city wall, but this situation is now more and more, the disadvantage of the Tiance army's strength makes Wang Houchun and others overstretched when arranging defense, the so-called fortification everywhere will be full of loopholes, plus the opponent's strength far exceeds the Tiance army, the result is that these Guiyi army gradually groped for the loopholes exposed when the Tiance army defended.

However, Wang Houchun obviously had enough psychological preparation for this, so when he saw the situation, he directly ordered the captain of the personal guard to inform Yang Yi to use a secret weapon, Molotov cocktails, in Xicheng, where the battle was fiercest and most dangerous. However, this incendiary bomb is not the kind of incendiary bomb that Wan Yi shot outside Tiger Hill Pass before. This is an incendiary bomb made by mixing petroleum with the latest sulfide extracted from the coal chemical industry by the Equipment Division, plus other flammable materials, and then packed with explosives. At the beginning, Li Xuanqing saw this kind of home-made incendiary bomb and almost directly ordered the equipment department to give up, the sulfides are basically poisonous, this one is not good, it does not hurt others, but hurts himself, you must know that just the oil is enough to burn in vain, it is enough for him to feel distressed, this idea to dig out oil in the shallow surface is not ordinarily difficult, if it is not for those Gansu and Gansu states, there is really no way to find oil so easily, if it is replaced with hot oil, the effect is not good, and the stickiness of oil is lost. What's more, if you want to engage in incendiary bombs, it is better to use the previous incendiary bombs directly. It's just that after Qin Yao tried it a few times, he still persuaded Li Xuanqing, Zuo Tiancheng and others to produce a batch and send it to the northwest, ready to see how the battlefield effect. For this kind of groping experiment, Li Xuanqing did not stop it. Unexpectedly, it was taken out by Wang Houchun at this time, obviously intended to be used as a killer feature.

Yang Yi naturally knew that although this kind of incendiary bomb was powerful, it also had great drawbacks, so while ordering his subordinates to quickly move the incendiary bomb over, he ordered all the soldiers to prepare wet cloths, ready to cover their mouths and noses at critical moments, and tear off their clothes directly if there was no wet cloth. Fortunately, when Yang Yi prepared the equipment to defend the city, one of them was to set up a cauldron on the city tower to boil water and pour it down, but the weather in the northwest in March was still very cold, and it was not difficult to boil the water, but there was still water on the city tower.

After Yang Yi gave the order, a full thirty incendiary bombs were quickly ignited, and then pushed out of the city wall, and at this moment, the defenders of the Tiance Army in Xicheng were in full fire, and all the weapons began to burst out, and the powerful scattering stream forcibly suppressed the Guiyi army under the city wall, unable to move.

The strange explosion of "bang bang bang" looked very dull in the explosion of the constantly firing artillery, but after the explosion of these incendiary bombs that were thrown down the city wall, they quickly scattered all kinds of flammable materials that were originally stuck together, and at the same moment, countless flames appeared from these objects, and a puff of fire spread rapidly around the explosion point. And with the appearance of flames, thick and pungent pale green gas began to appear out of thin air, and the smoke began to envelop the soldiers of the Guiyi Army who had just been splashed by sparks and then followed by their clothes that were set on fire.

"It looks like this incendiary bomb doesn't work very well." Although there was a chaos below because of the appearance of incendiary bombs, the soldiers of the Guiyi Army who were set on fire began to run around, because after flammable substances such as oil were ignited, these flames were difficult to extinguish, and after being splashed on the body, they began to ignite their clothes quickly, so one by one the burning people accompanied by a wail made the Guiyi Army be blocked from attacking at this moment. But Yang Yi shook his head after taking a condescending glance, obviously not satisfied with the incendiary bomb made by the equipment department, but the next moment he realized the power of this incendiary bomb, just a little inhalation of this gas, Yang Yi felt dizzy, quickly covered his mouth and nose with a wet cloth and took a few steps back, and hurriedly reminded the soldiers of the Tiance Army to cover their mouths and noses, and it was absolutely forbidden to inhale these terrible gases.

On the Xicheng side, because Yang Yi used incendiary bombs to force back the attack of the Guiyi army, and created a sea of fire and poisonous fog to make the Guiyi army stop abruptly, but Yang Yi didn't have time to check the results, and the remaining three city walls also rose a burst of pale green smoke one after another, obviously they also used incendiary bombs to fight back almost at the same time. In this way, although the soldiers of the Guiyi Army below suffered heavy casualties because of these poisonous fog and flames, so they suspended the siege, but the situation did not fundamentally improve, and the Tiance Army itself could not let go of its hands and feet because of the influence of the poisonous fog, and although Cao Rengui did not understand what was wrong, he thought of a countermeasure, and began to avoid the flames and poisonous fog, and constantly used the long-range catapult and bed crossbow and other weapons in his hands to shoot at the city tower, forcing the Tiance army not to dare to act too much on the city tower.

Shazhou City was temporarily stabilized due to incendiary bombs, but the headquarters of Su Xiaohu's Flying Eagle Brigade, which had been responsible for containing and harassing the Guiyi Army outside the city, was brewing a huge and risky operation at this time. Su Xiaohu was originally worried about how he should support the defensive battle of Shazhou City because of Cao Rengui's big attack, but after Luo Minghao said his plan, he nodded as soon as possible. Luo Minghao's method is very simple, that is, taking advantage of Cao Rengui's big attack, the chaotic situation on the battlefield, basically no one will care about his small team of more than 1,000 people, and try to disguise himself as the Guiyi Army to infiltrate Cao Rengui's series, so as to find an opportunity to get close to Cao Rengui's Chinese army, and arrange snipers to try to kill Cao Rengui under cover. As long as Cao Rengui dies or is at least injured, then the Guiyi army under the city will inevitably lose its discipline completely, and the combat power supported by the harsh military law these days will also collapse in an instant.

Luo Minghao's method is operable, because the Flying Eagle Brigade itself is a special operations force, although it is very difficult to sneak into the Guiyi Army in disguise and get close to Cao Rengui, and on the battlefield, Cao Rengui as the commander has a large number of elite Chinese army guards around him, in addition to the personal guards, but according to the ability of the Flying Eagle Brigade, it is actually possible to break through and find a suitable position. It's just that Su Xiaohu didn't have time to think about the whole plan before he was interrupted by the sound of a report behind him, and Xuan Yingwei had already reported that the Modao Battalion had arrived less than thirty miles north of Shazhou City. Moreover, Xuan Yingwei also brought a piece of news that made Su Xiaohu feel extremely excited, that is, Xue Yang's Third Corps had quickly arrived in Datun City, and in order to rush for time, the Third Battalion and the Fifteenth Battalion did not pay attention to the defenders of Datun City at all, but flashed from outside the city and went straight to Shicheng. Shicheng is an important town at the junction of Anxi and Shazhou, and it is also the bridgehead for Anxi to enter and exit the sandbank, if Shicheng is quickly taken by Xue Yang, then according to the current situation, Cao Rengui has been completely surrounded, as long as the sandbank holds on for more than two hours, the Modao battalion arrives, Cao Rengui will inevitably be defeated in one fell swoop, and then retreat to the west, and then fall into Xue Yang's ambush circle in Shicheng. In this way, the Guiyi army can be solved on the battlefield as a whole to the greatest extent, instead of causing the entire army to collapse and flee in all directions because of the killing of Cao Rengui, which will increase the difficulty of encirclement, suppression and appeasement in the later stage.

However, after thinking about these things clearly, Su Xiaohu still decided to lead the team to disguise himself and blend into the Guiyi Army. It's just that at this time, his purpose has changed from killing Cao Rengui at the first time to following Cao Rengui to make it impossible to get away when necessary, after all, the Cao clan has a huge influence in the hometown of the Guiyi Army such as Shazhou and Guazhou, if he is captured alive, then whether he surrenders or not, it can play a huge role in stabilizing the hearts of the people in the Tiance Army, plus Boxian Town has also been operating in Cao Rengui's hands for more than half a year, and the stability of the three places is enough for Su Xiaohu to decide to catch Cao Rengui when necessary.

Therefore, the Flying Eagle Brigade, under the leadership of Su Xiaohu, quickly pulled off the clothes and armor from the soldiers of the Guiyi Army who died on the battlefield, and then disguised all their weapons as soldiers who had retreated from the front line and retreated towards the Chinese army. And at this time, it was very beneficial to the Flying Eagle Brigade that because of the appearance of incendiary bombs, Cao Rengui had withdrawn the law enforcement team that had been on the front line, and began to arrange for the generals to collect the defeated soldiers, and then reorganized them on the spot, ready to be transferred to the rear army as a reserve, and sent their elite Chinese troops to start launching a new round of attacks after the strong wind dispersed the poisonous fog. In this way, except for a small number of people in the Flying Eagle Brigade who were coerced into the rear army, the rest of the manpower began to gradually infiltrate the Chinese army under the leadership of Su Xiaohu.

When Su Xiaohu's plan was decided to be implemented, the sandbank also reached the last moment, because Shi Jian was worried that the situation on the sandbank was not good, so he began to continuously fire smoke rockets less than thirty miles away from the sandbar to inform the news that the reinforcements in the city had arrived, so after learning that the reinforcements were not far away, Wang Houchun simply let go of his hands and feet, and ordered the defending troops to start pouring fire down desperately, no matter what kind of weapon they were, as long as they could kill the enemy, all of them moved up, The cannon with red barrels before was brutally poured cold water by the gunner, forcibly cooled, and then fired again regardless of the white water vapor of the cannon barrel, and the bed crossbow brigade behind him simply began to mobilize all the young and strong, regardless of whether they were aiming or not, they began to shoot downwards with their eyes closed. And the most terrifying is the mechanical crossbow force, all the components of the latest mechanical crossbow have become standardized parts that can be replaced in time, so that the number of mechanical crossbows has not decreased much until now, and countless crossbow arrows have been fired with all their strength, and the entire sky has been covered by this rapid crossbow arrows one after another, and the piercing whistling sound can even be clearly distinguished in the fierce artillery fire.

This madness of the Tiance army once again suppressed the Guiyi army, but Cao Rengui was ready to make a desperate bet at this time, according to his calculations, the reinforcements of the Tiance army will definitely arrive tomorrow at the latest, this is his last chance, if he can't do it before the arrival of the reinforcements of the Tiance army, he can only flee west again, enter Khotan and join Li Mingqi. Therefore, he didn't care about the casualties at all, and even the descendants of the soldiers around him who were brought out from the sandbank began to be directly sent to the battlefield.

It's just that what Cao Rengui doesn't know is that this is also his last struggle, not only the reinforcements of the Tiance Army have arrived at the foot of Shazhou City, but even his last retreat and base have been wiped out by the Tiance Army in one fell swoop, Cao Rengui and his Guiyi Army have reached the end.
