Zeng Zhilin, who was outside Youzhou City, also knew very well that the most important thing for the "Northern Route Army" now was to solve the problems on the side of Youzhou City in the shortest possible time, so that some people could be dispatched north to the front line of the Great Wall to assist the "Southern Route Army" in defending. After all, although it has the advantage of equipment, in the face of dozens of large and small passes that are connected like pearl necklaces on the hundreds of kilometers of defense line from Juyong Pass to Yuguan (Shanhaiguan), it will be very difficult for a crossing team of only 40,000 horses to be armed without missing a single point and not losing a single pass - not to mention that nearly 10,000 of these 40,000 people have to stay behind to protect the "Liangyuan", "Xianglong Fort", and the new production base as their fundamental and back roads. Therefore, after the capture of Youzhou, in addition to leaving the necessary troops to defend the city, the main force of the "Northern Route Army" will go north to support the defense line from Gubeikou Pass to Juyong Pass that Xu Shao'an's department is responsible for. In addition, a small number of men and horses will march westward and share the defense task with some of the 10,000 people who remain in the base camp to take charge of the defense of the line from Juyong Pass to Zijing Pass -- although the Military Department believes that it is unlikely that the Liao army will enter the states in front of the mountains from the west of Juyong Pass, out of consideration for danger, the committee still transferred some men and horses from the "Northern Route Army" to strengthen the defense of the western front, so as to prevent the Khitans from rushing in from the direction of the western mountain.

Now that the reinforcements of the Liao State can be said to be close at hand, the side of Youzhou City must be quickly decided. At the end of the fourth day of the fourth month of the lunar calendar and the beginning of noon in the ninth year of the Ying calendar (the sixth year of Xiande), Zeng Zhilin issued an order to the main force of the "Northern Route Army" that had completed the infantry cavalry formation and artillery erection. And with his order, the eighteen siege guns roared almost at the same time, and eighteen 130-millimeter wall-piercing shells roared out and flew towards the Danfeng Gate of Youzhou City and a section of the surrounding city wall two miles away -- the so-called wall-piercing bullet is a kind of bullet specially developed by the weapons department based on the armor-piercing shells used by ships in the previous life to blow up the city wall, and its warhead part is relatively hard and uses a time-delay fuse, which can explode after drilling into the city wall for a short distance, blowing up the thick city wall piece by piece, and then blowing up the entire section of the city wall.

Despite the fact that the charge in the wall bullet was small because the hard warhead took up most of the weight, the enormous power of the yellow powder still produced a very strong destructive effect. As the eighteen piercing bullets hit the Danfeng Gate and the surrounding city walls almost at the same time and exploded at the same time, eighteen clouds of yellow and black smoke suddenly burst out from the city gate and the city wall, and the entire city wall trembled, and the masonry and soil that were originally filled in the city gate to prevent the enemy from rushing into the city gate were splashed everywhere. The Liao soldiers who were directly above the explosion point even fell to the ground because of the huge tremors, including Xiao Buda, the supreme military commander of Youzhou City, who was standing on the Danfeng Gate to observe the opponent.

Seeing that the main general fell to the ground, the personal soldiers and entourage next to him hurriedly struggled over to help Xiao Buda, who had been smashed to the ground. As a result, as soon as they lifted the main general up, the second shell flew in on the other side. With a series of dull loud noises, Xiao Buda, who had just easily gotten up from the ground, was once again shocked to the ground along with those personal soldiers and retinue. And the section of the city wall under their feet has also been blown into potholes, and the originally smooth wall is full of large and small holes. Xiao Buda and his men had learned this time, and no longer rushed to their feet, but crawled to the west on all fours, hands and feet, in order to avoid the Danfeng Gate, which had clearly become the target of the enemy's shelling, and the surrounding section of the city wall.

After crawling for some distance in a very embarrassed position, Xiao Buda stopped and staggered to his feet. At this time, although I could still feel the city wall shaking from time to time, because it was far away from the center of the explosion, it would not be shaken down again. It's just that for Xiao Buda, the key now is not whether he will crawl in shame like he did just now, but how he should deal with the enemy's attack. Thinking of this, he subconsciously turned his head and looked at a relative who had been following him with an inquiring look, hoping that the other party could give him an answer. At this time, the entourage was so frightened by the sudden bombardment that his face turned pale and trembled, and his lips trembled for a long time, but he did not say a word. Seeing that his personal entourage had been frightened, it was obviously impossible to give him any more advice, Xiao Buda didn't blame the other party, but just shook his head helplessly. …,

Although his personal followers failed to give him advice, Xiao Buda now understood at least one thing, that is, this guy who had been a personal soldier by his brother's side, was separated from his master in the Battle of Baoxingzhuang, and finally escaped from that terrifying battlefield was extremely lucky, and what he said to himself was true-Xiao Dashuai's army of 70,000 did indeed encounter the most formidable and mysterious opponent in history, and ended up with a total annihilation; The enemy's weapons, especially firearms, are indeed extremely sharp, and they are said to be human flesh and blood, and even the thick walls of Youzhou City have no ability to resist in front of them; This army of unknown origin is by no means the Zhou army, because the firearms they use are not at the same level as what Cao Jiyun said at the beginning, and compared with the firearms of this army, the firearms of the Zhou army are not much stronger than the burning sticks.

After understanding this, there was no need for the advice of the entourage, and Xiao Buda also knew what he should do - instead of fighting against an army that he couldn't defeat at all, it was better to take advantage of the fact that Youzhou City was not surrounded by the other party now, and quickly flee from the place of right and wrong with his family and gold and silver, and go back to his hometown outside the Saiwai to live a few days of peace. Of course, as the commander of the First Army, Xiao Buda cannot just say that he can escape, or that he cannot run away so blatantly. First, he had to bring some of his henchmen and personal soldiers, otherwise, with a large amount of gold and silver, but without enough manpower to protect him, he and his family could easily become the "meal on the plate" of those bandits and robbers who were active in the mountains to the north. Second, the enemy army is only two miles away from Youzhou City, and if he escapes regardless of this, his 20,000 men and horses will inevitably collapse, and the enemy army will attack the city in a moment. And the escape of his own family will definitely not be able to go fast, and it will be completely over when he is caught up by the enemy. Therefore, the defenders of the city must not collapse before fleeing away, and must drag the enemy army for a while so that they can escape smoothly.

Therefore, Xiao Buda did not care whether the method was really applicable or not, and immediately followed the series of methods given by Cao Jiyun to deal with artillery attacks, on the one hand, he ordered his subordinates to leave the city except for a few people to monitor the enemy's movements, and the rest of the men and horses left the city head and took refuge in the hidden soldier cave under the city, and on the other hand, he sent someone to inform Han Deyi, who was "trying every possible way" to organize young people to prepare for "assisting" Han Deyi, who was defending the city, and once the city wall was collapsed by enemy artillery, it would immediately be repaired so that it could not be used by the enemy army to attack the city. And he himself was the first to take his own soldiers and entourage into the Tibetan Cave, and secretly sent his henchmen back to the house to report the news, so that his family members could make all the preparations, and when he found a suitable opportunity to leave, he escaped from Youzhou City as quickly as possible from the only unblocked Tongtian Gate in the north.

Just when Xiao Buda was shaken by the artillery fire and was waiting for the opportunity to escape, on the west wall of Youzhou City, Xin Feiyu had already begun to act after hearing the first cannon shot. He divided his thousands of men into three routes, the first of which was also the largest, consisting of the second regiment of the "Security Army". The regiment was divided into two and blocked both ends of the western city wall, preparing to block the Liao army on the north and south walls of the city wall that might launch an attack on their own side after discovering that there was an abnormal movement on the west city wall; The second road consisted of the second and third companies of the 9th Battalion of the 3rd Regiment of the "Flying Dragon Army". The task of the road is to rush down the city wall, kill the Khitan soldiers who are scattered around the city gate of Xianxi Gate, clear all kinds of obstacles used to block the city gate, and clear the way for the "wolf tooth camp" outside the city to enter the city; The third road consisted of a company of the nine battalions of the three regiments of the "Flying Dragon Army". This route was personally led by Xin Feiyu, and its main task was to kill the forty or fifty so-called liaison officers arranged by the Khitans on this side of the city wall, so that these Khitan soldiers who were called liaison officers and were actually monitors would go to report to their main generals.

After the arrangement was completed, the three people immediately took action. As a crucial step in whether the entire operation can be carried out normally, the elimination of the watchers in one's own team is naturally the first thing that needs to be completed. It stands to reason that since those Khitan soldiers were ordered to come to monitor, they should be scattered among the battalion leaders and subordinates in this so-called "good township villager" team, so that it is convenient to monitor their every move. However, in fact, as the development of the war became more and more unfavorable to the Liao army, the hearts of the Khitan people in Youzhou City became more and more fluctuating, and these forty or fifty Khitan "liaison officers" were also flustered, and they either got together all day to discuss their own retreat, or shrank at home to take care of their own money, ready to abandon the city and run away at any time, and no longer did their best to monitor those "good townsmen" who were deliberately arranged by Xin Feiyu and his officers under the deliberate arrangement of Xin Feiyu and his officers, and were considered by them to be nothing more than a group of rabble. So much so that today, despite Xiao Buda's strict order that "all 'liaison officers' must be in place", only seventy percent of the total number of Khitan monitors actually ascended to the top of the city, and they still gathered together to discuss how to protect themselves, rather than performing their own surveillance duties. …,

However, the uneven number of people did not affect Xin Feiyu's execution of Jihua, but allowed him to save some trouble. Xin Feiyu first summoned all the Khitan "liaison officers" present to his command post in the gate tower of Xianxi Gate in the name of studying the strategy of defending the city. After all the other parties arrived and sat down in the hall of the command post, with Xin Feiyu's order, the officers and soldiers of the first company of the third regiment and the ninth battalion of the "Flying Dragon Army", which had already been lying in ambush, opened fire at the same time under the cover of the rumbling artillery in Nancheng. Under the concentrated fire of hundreds of rifles and two light machine guns, the 34 Khitan "liaison officers" in the hall were instantly beaten into a hornet's nest and died.

The Khitans who were spying on themselves were solved, and the other two groups of people also moved. While the Second Regiment of the "Security Army" lined up at both ends of the city wall on the west side, preparing to resist the possible attack of the Khitans, the other two companies of the Third Regiment and the Ninth Battalion of the "Flying Dragon Army" also rushed down the city wall at the fastest speed, cleanly and neatly annihilated more than 100 Khitan soldiers who were responsible for guarding the gate of the city gate of Xianximen, and began to clean up the obstacles in the city gate hole.

Although when filling the city gate hole, Xin Feiyu's subordinates and the young men in the city who were hinted at by Sun Pan did some tricks and tricks, and cut corners in many positions. However, because there were Khitan people next to them to supervise the scene, they did not dare to make it too obvious at that time, so that although it was relatively loose, the entire city gate hole of Xianxi Gate was still blocked by various fillings from top to bottom. Therefore, it took nearly a pillar of incense for the officers and men of the two companies of the Ninth Battalion to reluctantly clear a passage between the fillers and blow up the exposed part of the gate with explosives.

Almost at the same time that a big hole was blown open at the Xianxi Gate, the "Wolf Tooth Battalion", which had been lurking outside the city gate for a long time and had long been suffocated, also rushed to the city gate like a tiger descending from the mountain, and rushed to the west city wall under the response of the comrades in the city.

As the "Wolf Tooth Battalion" entered the city, Xin Feiyu arranged for his subordinates who were familiar with the situation at the head of the city to lead the "Wolf Tooth Battalion" and the two companies of the Ninth Battalion to the south wall along the road, and on the other hand, he transferred all the horses of the Second Regiment of the "Security Army" to the north end of the west city wall, and cooperated with another company of the Ninth Battalion to block the attack of the enemy troops that might come from the north wall wall. At the same time, he also reported the current situation to Zeng Zhilin outside the city through the hand, signaling the other party to prepare for entering the city.

Xin Feiyu did his best here, and let the "Wolf Tooth Battalion" enter the city. On the side of the south city wall, Xiao Buda, who had waited in the cave for a long time, and did not wait for the enemy to carry out an artillery attack on the soldiers at the head of the city, walked out of the cave with a suspicious face, and carefully took his own soldiers and followers back up to the top of the city to observe. At this time, although the artillery attacks of the enemy troops outside the city were still continuing, the density of their attacks was no longer as fierce as at the beginning, and although they occasionally deviated from the distant attack points, the focus of their attacks had always been limited to the Danfeng Gate and the surrounding section of the city wall - even if the Danfeng Gate and the city walls of nearly a hundred paces to the left and right had been beaten to pieces, it was impossible to see the appearance of the city wall and the city gate at all. Even a general like Xiao Buda, who knew little about firearms, could now see that this kind of artillery attack by the other side was meaningless and purely a waste of weapons.

"Carrying out artillery attacks in a 'conventional' mode", "making senseless artillery attacks on the city walls", and "not sending infantry to attack the city even though a long section of the city wall has been completely collapsed", these unreasonable practices of the enemy forces outside the city were incomprehensible. Just as Xiao Buda was racking his brains to crack his opponent's intentions, there was a sudden explosion on the west side of the city wall, which had not made any big moves. And with this explosion, the entire western city wall seemed to be in a commotion. This situation shocked Xiao Buda, for fear that he had fallen for the enemy's method of attacking the south and the west - ostensibly shelling the southern city wall, and then taking advantage of the opportunity of his attention to be attracted, secretly sent troops to attack the western city wall, which was only guarded by the villagers.

As soon as Xiao Buda thought of this, he first secretly screamed that it was not good, and then planned to send someone to the western city wall to inquire about the situation. As a result, before he could call his heralds to him, there was a continuous "Bang!" from the intersection of the south and west walls. Bang!" loud noise, and the screams of the Khitan soldiers defending the city. This sudden change shocked Xiao Buda's heart, and he didn't care about sending any more heralds to investigate, so he quickly turned his head to look to the west. …,

The first thing that caught Xiao Buda's eyes was his own soldiers who were running over in a hurry, and these people kept looking back and back as they ran, their faces full of panic and panic. Beside them, they were followed by a group of soldiers dressed in colorful short fights, wearing equally colorful and strangely colored helmets, holding weapons similar to the muskets used by the Zhou army, but the firing speed was obviously much higher than that of the Zhou army's muskets.

Because of the previous defense of the enemy artillery attack, Xiao Buda has withdrawn most of the defenders to the hidden soldier cave under the city wall, at this time Xiao Buda himself went to the city, but because he did not understand the intentions of the enemy outside the city, so he has not ordered the defenders who have left the city to return to the city. Therefore, when the "wolf's tooth battalion" rushed to the southern wall, the enemy troops on the city wall were less than 1,000 people, and the enemy troops in front of them were only two or three hundred. This kind of liliang comparison put the "Wolf Tooth Battalion", which originally had an absolute advantage in weapons and training, in a more advantageous position, and they almost killed all the way as if they were in a no-man's land, and in the blink of an eye, they had rushed to the front of Xiao Buda.

It was only then that Xiao Buda recovered from his shock and attempted to escape. And several of his own soldiers came forward with swords, intending to fight for their lives to buy a little time for their master. It's just that at this time, the two sides are already close at hand, where is there a chance to escape and fight desperately. Without waiting for Xiao Buda to turn around and run onto the road, and without waiting for his own soldiers to take two steps, the dozen or so soldiers of the "Wolf Tooth Battalion" who rushed to the front opened fire almost simultaneously, and under the fire of two light machine guns and twelve rifles, Xiao Buda, his personal soldiers, and his entourage and more than a dozen other people were beaten into a sieve in the blink of an eye, and all fell into a pool of blood. Xiao Buda's corpse rolled from the head of the city to the bottom of the city along the horse road, frightening the hundreds of Khitan soldiers who were about to go to the city when they heard the sound. When they found out that it was their own commander who rolled down the city, they didn't know who shouted, and these hundreds of soldiers immediately dispersed.

The "Wolf Tooth Battalion" did not pursue this rout, and after clearing the enemy troops from the west city wall to the south city wall Danfeng Gate, they stopped the pursuit. On the one hand, Huang Hai commanded his subordinates to build a defensive ring around Danfeng Gate, and on the other hand, he sent a signal to Zeng Zhilin outside the city. There was not much time, and the main force of the "Northern Route Army" adjusted its formation and drove towards Youzhou City.

The main force of the "Northern Route Army" was only two miles away from Youzhou City, so when the other city walls on both sides and the Khitan soldiers in the city reacted and began to organize men and horses to counterattack on the west and south city walls, intending to recapture the breakthrough, the main force of the "Northern Route Army" had already entered the city through the Danfeng Gate, which had been blown up. Seeing that the main force of the enemy army had entered the city and the main general of their own side was dead, the rest of the Khitan army completely lost their fighting spirit after two unsuccessful counterattacks, and under the leadership of their respective commanders, they panicked and retreated to the only unblocked Tongtian Gate in the north of the city, intending to escape from Youzhou City.

However, in the face of the thousands of Liao troops swarming in, how could a small Tongtian Gate be accommodated, and the city gate hole was instantly blocked by human flow. In order to get a way out, the Khitan soldiers, who were eager to escape, insulted each other, pushed, trampled, and even slashed with knives. There was not much time, and the corpses in the city gate cave were piled up like a mountain, and they could no longer pass. Seeing that the escape route was broken, most of the Khitan soldiers were desperate, and they either wandered around aimlessly near the Tongtian Gate, or stood still, just waiting for the enemy to come and capture them. A small number of Khitan soldiers who had lost their minds climbed the city wall and jumped down the city regardless of it, but the result could only be broken tendons and a whimper. There are also a few vicious Khitan soldiers in line with the idea of "killing one is enough, killing two to earn one", turned around and rushed into the city, like crazy demons, regardless of men, women, old and children, they killed people when they saw them, and the vicinity of Tongtianmen suddenly fell into a bloody storm. Fortunately, the "Northern Route Army" predicted in advance that the Khitans might jump over the wall in a hurry and attack the common people when there was no hope of escape. Therefore, at the same time as the main force entered the Danfeng Gate, Huang Hai ordered the "Wolf Tooth Battalion" to rush into the city and rush straight to the Heavenly Gate, while completely blocking the Khitan retreat, and doing his best to prevent the other party from any behavior that endangered the people.

Although due to the timely arrival of the "Wolf Tooth Battalion", the massacre of the Khitan soldiers did not last long and was completely wiped out. But Rao was like this, and there were still three or four hundred people who fell in pools of blood, the vast majority of whom were Han Chinese. The atrocities of the Khitan soldiers aroused great indignation among the officers and men of the "Wolf Tooth Battalion", who, after slaughtering all the Khitan soldiers who had participated in the massacre, began to turn their guns on revenge at those Khitan soldiers who had not participated in the massacre, even though many of them had already surrendered to their knees and begged for mercy. Therefore, when Huang Hai got the news and rushed to Tongtianmen to stop the retaliation of the "Langya Battalion", there were no less than 2,000 Khitan soldiers who died at the gunpoint of the officers and men of the "Langya Battalion" -- most of them were Khitan soldiers who had abandoned their weapons and surrendered.

Although there were unconventional incidents such as the indiscriminate killing of prisoners by the "Wolf Tooth Battalion", it would not have any substantial impact on the war in Youzhou City. At the end of the afternoon of the fourth day of the fourth month of the lunar calendar in the ninth year of Yingli (the sixth year of Xiande), the "Northern Route Army" captured Youzhou City, and the second step of the "Jihua Operation of Building the Foundation No. 1" was successfully completed.
