After the end of the Battle of Fuzhou, the result was that the defenders of the Wusheng Army on the front line of Chuzhou also directly raised their hands and surrendered, so that Qian Biao's land forces disappeared, and the Tiance army pointed out, and the surrounding Lu Guangchou, Lu Guangmu and Liu Yin and others were almost sleepless at night, and sent envoys to Quanzhou, Fujian, trying to mediate the contradictions between Wang Chao and Fan Hui, and unanimously deal with the impact of the Tiance army. It should be said that according to their southern forces, they could not find out the combat power of the Tiance Army before they had contact with the Tiance Army, but the caravans of the Tang Empire frequently haunted their territory, so they began to send secret people to contact these caravans at the same time as forming an alliance, trying to find a way to obtain the intelligence of the Tiance Army's military.

However, according to the idea of the Jiangnan Front Command of the Tiance Army, for the time being, they have little interest in their alliance, and even Hu Xiaosi, who has always liked to join in the fun, is not very interested, but the three of them began to focus on the rotation training and rest of the troops, and the troops on the southern front have been fighting for half a year, and there is almost no time to rest. By the way, I don't want to disturb the summer harvest and autumn planting in the south.

However, the eastern and central routes were rested on a large scale, but the western route army suddenly exerted its strength. In late July of the second year of the Apocalypse, Xue Yang asked Xu Ying to lead a large group of men and horses to officially attack Tanzhou, and he personally led the third battalion and the fifteenth battalion to bypass Tanzhou and attack Changsha at night, and directly attacked Ma Yin's office. This move made Ma Yin on the front line in Tanzhou almost break out in a cold sweat. At this time, Xu Ying's offensive also reached its peak, the 100,000-strong army surrounded Tanzhou, and all kinds of siege weapons began to gradually exert their power, coupled with the stagnation of the Western Route Army for so long before, Ma Yin felt that the large team in front of him was actually a false move, and its killer weapon was also in the hands of the small force that had arrived in Changsha. In addition, Xue Yang himself was also on the front line in Changsha, which finally made Ma Yin decide to lead the main force from Tanzhou City to withdraw secretly, and then march day and night to prepare for a surprise attack on Xue Yang in Changsha, destroy this small force deep behind the enemy, and then return to the division to fight the main force of the Tiance Army by surprise. In order to achieve the effect, Ma Yin found a stand-in who was very similar to himself to stand at the head of Tanzhou City every day to boost morale, and by the way, he also had the heart of the Tiance Army under the city.

It's just that Ma Yin's actions did not hide from Xuan Yingwei's eyes, since Xue Yang decided to do this, he was naturally prepared early in the morning, and the person in charge of Xuan Yingwei Chudi personally infiltrated Tanzhou, almost at the same time as Ma Yin left Tanzhou, the news of Xuan Yingwei here also spread out of Tanzhou City. After Xu Ying received the notice from Xuan Yingwei, he began to secretly transfer manpower to let Li Shenfu lead Ma Yin to advance, and at the same time fly pigeons to Xue Yang on the front line in Changsha.

After arranging these, Xu Ying arranged virtual troops around Tanzhou, and at the same time began to attack Tanzhou, the artillery battalion and the blasting group broke into the city gate almost in half a day at the same time, and after a violent explosion, the entire city gate of Tanzhou flew into the air, and the new generation of gunpowder technology enhanced the power of the blasting barrel to the extreme, and this explosion almost made Xu Ying and Tiance Army themselves open their mouths. So much so that many soldiers of the Western Route Army ran to the equipment department to thank them, and the latest products of the equipment department almost made the soldiers love to death.

However, Xu Ying reacted immediately, and with a wave of his right hand, all the Tiance troops rushed into Tanzhou City, and the stunned Chu army was forced to retreat step by step in the face of the wolf-like Tiance army, and Tanzhou City was also successfully taken. Xu Ying, who entered the city, could not appease the people and clear the other scattered soldiers, and immediately asked the mountain battalion to escort the artillery battalion and the people from the logistics department to set off to support Changsha. Xu Ying's move also laid a solid foundation for the later Battle of Changsha. The artillery battalion appeared from the flank at the critical moment, and the explosive packs falling from the sky and the sound of explosions rolling all over the ground made the blood boil the blood of all the officers and men of the Tiance Army who were in a deep stalemate, thus reversing the situation and creating a miracle.

After Xu Ying did this, he began to mobilize troops to sweep other states and counties near Tanzhou, and quickly established a military management area with Tanzhou as the center, constantly attacking the surrounding Ma Yin forces. At the same time, Pegasus reported to the headquarters the summary of the battle situation of the Western Route Army, informed the headquarters of Xue Yang's movements, and requested that logistics troops be sent to replace the field troops as soon as possible.

At this time, Xue Yang on the front line of Changsha was also pondering the time when Ma Yin would return to the army, and began to plan the ambush location. Changsha is a thousand-year-old city, surrounded by abundant products, it can be regarded as an important town in the southwest, and it is also very prosperous and densely populated, so it is not easy to find an ideal ambush location. Moreover, the 3rd and 15th Battalions advanced lightly, and did not carry many offensive weapons, and they only made a feint to attract Ma Yin to come to Changsha City to help.

"Dashuai, why don't you choose the south of Changsha near Qinggangpo? It is close to Yunmeng in the west, Changsha in the north, and there are mountain slopes winding in the east, which is a relatively steep place. As long as our actions in Changsha are reasonable enough, Ma Yin will inevitably give up reconnaissance and lead the army to advance. Li Yang pointed to the location of Qinggangpo and said: "When the time comes, the marshal will command the third battalion to attack Changsha City urgently, let the defenders in the city continue to send messengers for help, and my fifteenth battalion will lead the army to ambush on the Yunmeng side first, and Ma Yin's army will inevitably force through this road regardless of obstruction." After the battle between me and Ma Yin began, the commander withdrew his troops from Changsha and reflexively participated in the siege, and with the speed of the third battalion, he could inevitably rush to the battlefield in time and participate in the flanking attack from the northeast. ”

"It's just that our two armies together are only more than 30,000 people, and according to Xuan Yingwei's report, Ma Yin has brought 100,000 people back urgently. Changsha is where Ma Yin's lair is located, but I am afraid that when the time comes, we will fall short if we let the other party stand out. After Li Yang finished speaking, he smiled bitterly: "I just don't know when the reinforcements from the deputy marshal's side will come over." ”

"Don't worry, Li Shenfu is estimated to follow Ma Yin and attack Ma Yin from behind." Xue Yang did not hesitate to say about Xu Ying's actions: "There is no perfect plan for the decisive battle between the two armies, since you have already acted, you must believe in your brother." You immediately led the 15th Battalion to set off at night to ambush Qinggangpo. After dawn, I led the third battalion to attack the city. According to the marching speed of Ma Yin's army from Xuan Yingwei, it is estimated that they will enter the vicinity of Qinggangpo early the day after tomorrow. More than 100 miles from Changsha to Qinggangpo, I want to set off tomorrow night at the speed of the third battalion, just in time to enter the battlefield with the other side. ”

Li Yang nodded and went to rectify the army, and quietly led the army to leave that night, and Xue Yang also went to send a letter to Ma Yin to ask for help in order to let Ma Yin speed up and instruct the Xuanying Guard's secret guard to pretend to be the defenders in the city, and said that the other party's whole army gathered outside Changsha City, attacked day and night, and prepared to take Changsha before the main force of the Chu army returned to help. This letter was like a talisman that Ma Yin couldn't care about anything else, and began to speed up and rush back despite the fatigue of the soldiers.

And the next morning the third battalion attacked the city as promised, in order to achieve a realistic effect, Xue Yang lit countless firewood and grass on the battlefield, thick smoke was filled, the fire was raging, and the ballista troops forcibly suppressed the opponent's defensive firepower, and the soldiers from all walks of life began to approach the city wall to blast, and the explosion sound combined with the thick smoke made the defenders in the city unable to tell how many people were outside the city, and even under the thick smoke, the soldiers defending the city could not stand on the city wall for a long time. Xue Yang's smoke offensive has been the true biography of Hu Xiaosi, using catapults to throw all kinds of strange things onto the city wall, from common stones, to hornet's nests to burning poisonous weeds, almost another copy of Taiyuan City.

This farce generally lasted for a day's siege battle, although the third battalion did not climb the city wall, but for the defenders in the city, it was not as good as a real fight, the other party did not play cards according to common sense, so that everyone was frightened, and the next moment the other party would use any method to deal with themselves. Finally, the Tiance army Mingjin withdrew its troops, and there was almost a cheer on the city wall, and several brave Chu soldiers shouted directly, if you come again tomorrow, can you come with some regular means, even if it is cut, it will be worth it.

However, after nightfall, the soldiers of the third battalion outside the city quietly evacuated from the camp in batches, and in order to cover up his whereabouts, Xue Yang repeated his old tricks, allowing people to light countless wet firewood and grass outside the camp, and completely covered all traces under the dense smoke, and the direction that blew after night was just facing the city, and the billowing smoke flooded the city tower again, and the defenders who couldn't tell the target at all were choked so that they couldn't open their eyes, naturally they couldn't find that the Tiance army had actually quietly withdrawn from Changsha City and advanced towards Qinggangpo.

In the darkness, the 3rd Battalion sped along a pre-surveyed path under the few torches. And the 15th Battalion, which has arrived at Qinggangpo, has also done all the camouflage work, and the Military Academy of the Tiance Army has basically systematically summed up a set of methods in the camouflage discipline. Moreover, in order to prevent Ma Yin from sending forwards into Qinggangpo in advance, Li Yang ordered all soldiers not to light fires at night, and all food was dry food.

In fact, it doesn't matter if these are true, the dry rations of the field troops are actually doing quite well. It's just that the weather in July is a hot period in the south, and there are too many mosquitoes, and this night can make these soldiers of the 15th Battalion suffer, many people are bitten and can't stand it, and a slap can kill a dozen mosquitoes full of blood. This scenario was not alleviated until the investigators who came out brought in the exact information. This hardship made the soldiers of the 15th Battalion put all the accounts on Ma Yin's head. In fact, in the later battle, the 15th Battalion was the most difficult to fight, but at the same time, it also had the most abundant results, not only captured Ma Yin himself alive, but also ranked in front of the 3rd Battalion for the first time in the number of enemies.

The soldiers of the 15th Battalion rested until midnight, and immediately entered the camouflage fortifications early the next morning to stand by. And the personnel in charge of reconnaissance also passed on the movements of the Chu army in an assembly line, and when Li Yang learned that Ma Yin had only rested for less than three hours a day in order to speed up the march, a smile appeared on his face, so the combat power of the tired march must be greatly reduced, and his own disadvantages in Qinggangpo will inevitably be infinitely magnified.

At this time, the troops of the third battalion of the Tiance Army had also arrived near Qinggangpo after a night of rapid marching, almost at the same time as the Chu army. It's just that Xue Yang was not in a hurry to let the third battalion enter the position, but rested on the spot to replenish his strength. At this time, colorful smoke rockets suddenly rose on the front line of Qinggangpo, and the colorful smoke columns rising in the sky were extremely eye-catching under the illumination of the morning sun.

"Commander, the fifteenth battalion has already exchanged fire with the other party." The guards behind Xue Yang pointed in the direction where the smoke rocket rose and shouted, "Let's hurry over too, right?" ”

"Order the troops, set off immediately in a quarter of an hour, and we will break into the battlefield in the direction of the northwest foot of the mountain." Xue Yang nodded and ate all the dry food in his hand.

However, Xue Yang's side entered the battlefield in a good time, but Li Yang's fifteenth battalion suddenly launched an attack when more than half of Ma Yin's army entered Qinggangpo, and the neatly arranged fifteen ballistae roared in an instant, and the whizzing crossbow arrows shot the unprepared Chu army to the ground in pieces, and at the same time, the five thousand archers who had been ambushed in advance bent their bows and arrows at the same time, and the dense arrows rose into the sky, and the arrows glowing with black light instantly covered the sky, shrouding the Chu army in this metal storm.

This upheaval almost made Ma Yin of the Chinese army fall off the horse, he thought that he would encounter an ambush on the way back to the army, but what he didn't expect was that it was near the door of the house, and it didn't seem that this posture was harassed by a small force, so as to delay his return to the army, and eighty percent really wanted to ambush himself.

But now Ma Yin didn't want to delay near Changsha, and directly ordered the troops to adjust their deployment, the front army continued to march towards Changsha, and he divided the army to attack the position of the fifteenth battalion, fortunately, the position of the fifteenth battalion ambush was close to the Yunmeng generation, the terrain was low and flat, there was no danger to defend, and his 100,000 army was crushed by, and any ambush would not play much role in the face of absolute strength.

Ma Yin, who calmed down, was a little strange while sending troops to attack, why didn't the army choose the opposite mountain these days, the advantage brought by condescending is not comparable to the current position. Thinking of this, Ma Yin glanced back at the opposite hillside, but he didn't expect that he had just thought of this, and suddenly a group of men and horses drove out on the opposite hillside, rushing towards his forward army at a very fast speed, and what surprised him was that these people were running while bending their bows and arrows, shooting forward, and they actually stopped their forward troops in the middle of the charge. The two collided.

"Lord Qiqi, there is a soldier and horse behind our army who have arrived, and the flag is unknown, and they are attacking our rear army." Before Ma Yin could react, the sound of the guards behind him came again. This voice completely woke up Ma Yin, he was calculated by the other party, and Changsha was attacked as a feint.
