On the first day of the seventh month of the fifth year of the Apocalypse, the Southern Advance Corps went south from Boluo Prefecture. As the news of the Saffarid army scouts quickly moved south to the army of the Governor's Mansion of Shufengdu, everyone was immediately ordered to prepare, and countless soldiers drove out of the city to check whether the various fortifications arranged were in good condition. The southward movement of the Tiance army meant that the time had come for the two sides to fight for the life and death, but to their surprise, this huge army of nearly 100,000 people disappeared from everyone's sight after leaving Boluo Prefecture, and the follow-up scouts did not find any clues at all, as if they had completely disappeared. When things go wrong, it must be a demon, and the Safarid front-line command began to hold a special meeting on the whereabouts of the Tiance army. Because there are only a few strategically important places in the south, when the Fengdu Governor's Mansion is gathered, if the Tiance army wants to avoid the front and achieve greater results, there is only one place - the royal capital of Xiliuzhou. This inference frightened everyone, and someone brought more news again. Almost overnight, it was written that the Fengdu Governor's Mansion was rumored in the city that the Tiance Army would attack the Xiuxian Governor's Mansion and completely uproot the two barriers in the north of Xiliuzhou. Originally, this kind of rumor did not have much reference value at this time, but what could not be stopped was that at this time, Qin Kong's secret son arranged inside the Saffari began to send an urgent messenger for help according to the instructions, claiming that the Xiuxian Governor's Mansion was attacked by the other party's army, and the city was in danger. In this way, in the actual intelligence infiltration, Qin Kong's arrangement played a decisive role in a series of later wars, it was really because of such intelligence to mislead the Safar people to make wrong decisions, and it can even be said that they did not understand one thing until this time, although their army at this time was more than three times more than the Tiance Army's southern marching corps, but they had long lost the initiative in the war. In this way, when the Saffarids sent reinforcements to Xiuxiandu Prefecture and Xiliuzhou at the same time, especially the news that 30,000 royal court guards were sent back to Xiliuzhou, was quickly transmitted back to the headquarters of the Southern Advance Corps and the two corps commanders on the front line, the balance of war began to tilt rapidly towards the Tang Dynasty according to Gauss's plan.

At this time, the Anxi Corps, which was under the city of Xiuxian Governor's Mansion, had not yet begun to attack the city. The speed of the Southern Advance Corps has reached the extreme since the departure from Boluo Prefecture, in order to pursue speed to catch the other party off guard, Zhang Sheng even threw all the artillery and baggage troops behind, and personally led three battalions of elite men and horses to gallop more than 700 miles southeast from Boluo Prefecture to the southeast, and when they arrived at the city of Xiuxian Governor's Mansion, almost everyone was tired and sleepy. Therefore, Zhang Sheng had no way to attack the city at the first time, and even in order to confuse the defenders in the city, he had to arrange a large number of suspicious soldiers to scare the opponent and buy time for his soldiers to repair. Therefore, by the time the Anxi Corps recovered its combat strength, it was already the eighth day of the seventh month, and at this time, the baggage troops and the other two battalions that had been left behind had also caught up. After the artillery and blasters took turns to move forward, the huge castle of the Governor's Mansion was forcibly blasted open, and Pang Lingming, who was in front of the rubble, took the lead in leading the team into the city and began to start street fighting. Under the guidance of the pre-arranged secret guards in the city, although the Anxi Corps was not familiar with the terrain in the city, relying on these pre-negotiated signs and codes that appeared on the way, Pang Lingming was inseparable from the other party, and even relied on the close support of mortars and grenades to constantly squeeze the opponent's living space. Countless battle teams of ten or twenty people were scattered throughout the city, and the sound of rifle bullets cracking through the air and the roar of shells after exploding continued for a whole day before gradually ceased. More than 30,000 elite Safarian troops were almost wiped out, and only a few thousand laid down their arms at the last moment. As a result of the battle of the Xiuxian Governor's Palace, the elite directly under the command of the Safarid royal court were constantly annihilated by the Tiance army, and this was the most important basis for the Safar Caliphate to suppress the domestic opposition and maintain his rule. However, at this time, Zhang Sheng did not dare to relax at all, and almost immediately after the battle, he commanded the last few thousand captives to seize the time to repair the city wall that had been blown up by himself before, and at the same time let Pang Lingming lead the army out of the city and camp outside the city to wait for the other party's reinforcements to arrive. Unlike the reinforcements on the side of Xiliuzhou that were 30,000 royal court guards, the exact number of reinforcements on the side of the Xiuxian Governor's Mansion did not send back an accurate number, so Zhang Sheng did not dare to be careless at all, especially when his troops had been fighting fiercely for so long without rest, and when the basic combat potential was about to be exhausted, it was impossible to last long just by relying on confidence after a sustained victory.

However, Zhang Sheng didn't have time to think of anything else, and almost in the afternoon of the same day, Saffari's reinforcements had already arrived in the city, and the battle began almost at the same time. However, Zhang Sheng did not let Pang Lingming's troops outside the city participate in the battle at the first time, but instead commanded the main force in the city to rely on artillery to attract opponents to attack the city defense. The huge gap in the wall, which had just been repaired by less than a third, apparently also gave the Safarids an opportunity, and immediately gathered their forces and immediately threw themselves into battle. Although the Safarid people were in a hurry and basically did not prepare many siege weapons, the other party obviously had their own preparations, and the nomads had long liked to use scratching to constantly peel off similar to this kind of stone wall, and under the countless scratching back and forth, the various stones on the city wall would gradually be peeled off and break into the city. But Zhang Sheng also wanted to use this opportunity to consume the other party to death in the city. Therefore, at the beginning of the battle, he continued to strengthen his firepower, and after inflicting heavy casualties on the opponent, he ordered the troops near the gap to weaken the fire attack, attract the opponent closer, turn this place into a meat grinding ground for the Safarids, completely consume the opponent's living strength, and win the opportunity for Pang Lingming outside the city to counterattack. In this way, the counterattack of the Anxi corps was sometimes strong and weak, and there were constantly defensive loopholes found by the opponent, and after the other side sent troops to attack, the other side seemed to react and strengthen the firepower to drive the Safar army out, and gradually the number of the Safar army in this attrition also decreased rapidly, and the cavalry unit that was originally 50,000 people full of personnel was killed and wounded more than 10,000 people in the afternoon attrition. After nightfall, when the other party gave up the attack and was about to retreat, Pang Lingming continued to lead the army to sneak attack the opponent's camp all night, disturbing the other party's peace. Finally waited until dawn, when almost all the Safarid people were preparing for the next day's battle with black circles, Zhang Sheng suddenly launched a full-line attack, and the main force of the Anxi Corps suddenly drove out of the city, and the battle started again, this time it was the turn of the Anxi Corps to attack, under the attack of strong firepower, the Safard cavalry, who had lost the initiative on the battlefield, could not compete with the Tiance Army at all, and were killed on the spot in pieces. Considering that there was still a big battle waiting for him in the future, Zhang Sheng had no intention of capturing the prisoners, and his delay in giving the order also caused the soldiers of the Anxi Corps on the battlefield to simply let go of their hands and feet, and the bloody massacre began outside the city. By the time the army was collected, almost all of Safar's 50,000 troops had been killed, and less than 10 out of 10 had escaped. The strong bloody atmosphere and the corpses all over the ground also made the people in the Xiuxian Governor's Mansion who were summoned to clean up the battlefield after the battle tremble, and the eyes of the members of the Xuanying Guard's secret guard who looked at the few people but still controlled the situation in the city were full of fear.

After Zhang Sheng collected his troops, he hurriedly arranged the follow-up matters in the city of the Governor's Mansion of Xianxian, and then led the army out of the city to the south, and all the defenses in the city were handed over to the secret guards to deal with. In the next battle, if the Tiance army defeats the main force of the Saffarid in one fell swoop, then it will not matter the situation on the side of the Xiuxian Governor's Mansion, so Zhang Sheng explained that if there are other people in the city who can't stop it, they can temporarily give up the Xiuxian Governor's Mansion and wait for the main force of the army to come back.

However, when Zhang Sheng led the army south, in fact, Tieliang's side was almost over. Although the 30,000-strong Royal Court Guard was not incomparable in number with the reinforcements from the Xiuxian Governor's Mansion, the Royal Court Guard was known as the most elite unit in the Safar country, and even surpassed the heavily armed spearmen of their Zhenguo Imperial Forest Army. Therefore, it was not very easy for Tie Liang to win on his side, and in order to quickly take down the opponent, Tie Liang only slightly blocked the opponent's reunion footwork after encountering the opponent, and immediately ordered the whole army to enter the counter-charge. In this way, although the battle dragged out to the tiebreaker as quickly as possible, it caused a huge loss to the heavy cavalry. Although the heavy cavalry battalion relied on the power of mortars and grenades to curb the cavalry's advantage over the infantry, and the speed of the other party did not rush up after the two armies encountered, the result of the hand-to-hand combat was that many soldiers in the heavy cavalry battalion had no time to reload after five bullets were exhausted, and could only insert bayonets and go up to hand-to-hand combat. If it weren't for the very timely movement of the Anxi Corps to the south, and the Safarids did not have reinforcements in the direction of either the Fengdu Governor's Mansion or the Wangdu of Xiliuzhou, I am afraid that the heavy cavalry battalion would really be very dangerous.

However, not long after the two converged, Gao Sijiye and Qin Kong secretly interspersed from the vicinity of the Fengdu Governor's Mansion with the men and horses of the headquarters. Since Gauss Ji took the secret path arranged by the Dark Guard, Gauss Ji still didn't know anything about the previous battle situation. But when he heard Tie Liang say that the heavy cavalry battalion was only in the early 40,000s at this time, he couldn't help frowning.

"Deputy marshal, I think the first thing is to feint on Xiliuzhou to attract the opponent's main force to the south, besiege the city and send reinforcements, and secondly, we need to do a good job of fortifications to wait for work." Qin Kong saw that Tie Liang's face was not good, and knew that he was still heartbroken about the loss of this battle, so he shook his head and said: "I will immediately arrange for the secret guard to send someone to spread the news of our two-way victory, and then send someone to disguise as a rescue officer from Xiliuzhou to write the Safar camp of the Fengdu Governor's Mansion, so as to disturb the other party's military morale." ”

"You can do it. Tie Liang, in the past two days, you have arranged for people to follow the Anxi Corps to dig trenches and battlefield traps on the spot, and this matter cannot be careless. Gauss patted Tie Liang on the shoulder and said, "I will ask the medical staff of the field hospital to hurry up and treat the wounded, this battle is mainly due to the number of wounded, but it is not as serious as you think." ”

"Don't worry, I'll pay attention." Tie Liang took a deep breath and calmed down his mood before continuing: "In this battle, Lao Zhang and I annihilated a total of more than 80,000 reinforcements, plus the 30,000 people in the Xiuxian Governor's Mansion itself, which means that we have already defeated 110,000 of the opponent's living forces. At this moment, there are only about 200,000 people left on the side of the Fengdu Governor's Mansion, and the ratio of the number of enemies and friends has dropped to two to one, and I think we can win this battle. ”

"Whether you can win this battle depends on whether your trenches can be dug well, and you have more experience than the Anxi Corps, so I will immediately arrange the most effective people to take the people of the Anxi Corps to me to turn all the hillsides in front of me into our trench positions." Gauss Ji led everyone to the outside of the camp and pointed to the gentle slope under his feet: "This is the main road to curb the front out of Xiliuzhou, and there is no other road nearby, unless they are willing to take a detour of more than 200 miles from the south, but if they want to make a detour, if they are pursued by our tail, they will definitely collapse the whole army." And from the fact that the royal court guards hurriedly went to Xiliuzhou from here before, it can be seen that they will inevitably go here. Your mission is to keep it here. Gauss's words revealed a hint of coldness, but everyone understood what he meant, this was the last battle, if the main force of the Safar army was defeated by himself, then not only the Xiliuzhou in the distance would go down without a fight, but even all the cities and towns in the entire Safar country would lose their resistance because the main force was wiped out.

After Gauss sent Tie Liang and Zhang Sheng to repair the trenches, Qin Kong walked over and said, "Isn't Dashuai Bi worried that when we are fighting with the main force of the Safar army here, the only remaining 30,000 royal court guards in the city of Xiliuzhou will go out of the city to attack us?" When the time comes, it will really be wrapped around the front and back. ”

"Come out, come out, although our troops are not enough, but look there, don't we still have an army?" Gauss pointed to the logistics team in front of him and began to light a fire and cook, and said with a smile: "Although our logistics team cannot be compared with the field troops, they have all undergone strict training from the recruit department, and positional warfare is not much worse than that of regular troops. Besides, it's just Xiliuzhou, I have a way. Gauss Ji shook his head and didn't take Qin Kong's worries to heart at all, but said, "You secret guards have a great responsibility, and you must find a way to attract the other party over." Although they will inevitably go south after Xiliuzhou is surrounded, if it were me, they might not go straight to Xiliuzhou, so pay attention to yourself. ”

"You can rest assured at this point, after all, their caliph is not you." Qin Kong also sighed and said: "Speaking of fighting, I found that these people are really worthy of being barbarians, where are the opponents of those of us who have been influenced by the sages and soldiers for thousands of years. They are fighting back and forth, in fact, just a few tricks. Moreover, Xiliuzhou is the foundation of almost all the high-level leaders of the Saffari, and it is also the hometown of the elite troops of their royal court, they must come back, otherwise they are afraid that the morale of the army will be completely destroyed immediately. You must know that in addition to the elite directly under the royal court of about 100,000, the rest are actually young and middle-aged people recruited from various tribes in the southwest, to put it bluntly, they are a rabble, and it is okay to fight a tailwind war, if it is a headwind, they will become our best helpers. The disdain in Qin Kong's words looked at Gao Siji, and he couldn't help but laugh himself, "I see that you are really condescending to stay in Xuanyingwei, if you don't go back, I will talk to Xiao Si and let you enter the General Staff." ”
