Under Jianshui City, Chai Jia's 50,000 troops have surrounded Jianshui City, and the new artillery attached to it has also been pulled out by him, and the field troops of the Tiance Army have now officially removed the explosives package from the heavy weapons, and some of them have been handed over to the National Guard, and some of them have been directly changed into crossbow arrows and a small number of troops to be used as accompanying infantry weapons.

However, Chai Jia was interrupted by the envoy of Long Xun, the former lord of Nanzhao, and suspended the attack before Chen Yu and the General Staff were instructed, but he was not idle, in addition to contacting Xue Yang in the north, he also found Qin Kong, the person in charge of Xuan Yingwei in Nanzhao. Qin Kong brought a major news that great changes would occur in Nanzhao's country in the near future, and suggested that the front-line army temporarily lay down its troops and suppress the dominant side with its strength, and at the same time take advantage of the left-handed fisherman.

There is no problem on Chai Jia's side, anyway, he has to wait for the officials of the Ministry of Foreign Affairs to arrive before making a decision, Chen Yu's side has not yet rushed to the profit city, but at this time, Xue Yang's army on the northern front has no way to abide by this agreement, Xue Yang has already ambushed the main force of King Liu who withdrew from Mangbu in the southwest of Mangbu City, and when Xuan Yingwei delivered the news, even Xue Yang's third battalion and mountain battalion had already fought with King Liu's soldiers and horses, so naturally there was no way to withdraw. However, Xue Yang thought about it, Mangbu was still far away from the Erhai region, the ruling center of the Nanzhao Kingdom, so he didn't pay attention to it, and continued to let the third battalion attack, enter the battlefield from the flank of the mountain battalion, and surround King Liu's 50,000 army.

Liu Wang is actually one of the three small tribes in Nanzhao, and has been the vanguard of Nanzhao to maintain its rule, this time Zheng Maisi transferred him to the south to judge that the attack of the northern Tiance army is a false army, so he is ready to shrink the main force to the east and south coast of Erhai Lake, and is ready to concentrate his forces to encircle and annihilate the Chai Jia Corps first, but what he didn't expect was that he just went out of Mangbu City for more than a hundred miles and plunged into Xue Yang's pocket.

And what frightened Liu Wang the most was that this group of Tiance soldiers had a musket in their hands, and after hearing only the sound of a ping-pong gunshot, their troops fell out of thin air, and this kind of shadowless attack made his troops unable to defend at all. Liu Wang even personally grabbed the body of a fallen soldier and came to check, only to see that the soldier had a finger-sized hole in his chest, and blood was coming out of it endlessly, but he couldn't find any other traces.

"What the hell is this? Put up a shield for me to cover, rush up, rush up and the willow god will bless us. All Liu Wang could think of was to put up the big shield, and then urge the soldiers to step forward and start a white-knuckle battle with the other party as soon as possible, otherwise, relying on the opponent's continuous shooting method, his soldiers would definitely be treated like rabbits. But what he didn't expect was that even though a big shield was erected on the front line, the casualties of the soldiers did not decrease, and these ghost things were able to penetrate the shield and kill the soldiers behind directly.

"Order each team to perform a three-stage shooting, and the marksman will give me the officers and generals of the opposing side to click and kill." Xue Yang stood on the hillside on the side and led the personal guards to continuously convey instructions and adjust the deployment. He is still very satisfied with the power of the musket, and the density and time interval of the breech gun's vitality are also made up for by the three-stage combat method, but the penetration ability of the Mini bullet makes him dissatisfied, and the wooden shield or cowhide shield of ordinary soldiers can naturally drill through, but the Tiance Army's own stainless steel shield has no way, and the bullet explodes directly after hitting it.

However, compared to this battle, the power of the Mini bullet is amazing enough, 50,000 against 50,000, with the support of superior weapons, Xue Yang quickly ended the battle, and the troops of Liu Wang of the brigade were completely beaten to the ground, and they were not given a chance to meet each other at all, and even Liu Wang himself was killed by the sharpshooter of the Tiance army and lost his command, and the army of Nanzhao completely lost the ability to adapt, and also lost the only opportunity to find the flaws of the Tiance army. This made many Tiance soldiers quietly put back the bayonets they had already taken out.

Although this war is very ordinary, it is very precious for generals such as Tiance Army and Xue Yang, because this is the first time that the musket has experienced the baptism of actual combat, and the strong firepower projection and new tactics have made many generals invariably begin to put forward various ideas in the combat diary, based on the three-stage tactics, and soon these generals figured out how the musket team should be deployed under different combat conditions such as encounters and positional battles, and how to improve the firepower projection to ensure that the enemy is blocked.

The only regret that Xue Yang felt was that because he was in an ambush battle, and the terrain in the northern part of Nanzhao was too complicated, all the artillery was left on Xu Ying's main side of the army. However, Xue Yang didn't think much about it anymore, and after handing over the prisoner to his deputy to arrange the handling, he began to think about the news sent by Xuan Yingwei before, if there was really a change in Nanzhao's country recently, I was afraid that the Tiance Army could really fish in troubled waters. It's not that you can't beat it, but to take Nanzhao with the smallest casualties, and after the war, it will reduce a lot of pressure, avoid killing too much and leading to local political instability in the later period, compare yourself These people are now doing the war of annihilation, although Nanzhao was a vassal state of the Tang Dynasty before, but after all, the country name has been established, if you use bloody means to subdue Nanzhao, the people at the bottom are afraid that they will not accept it, and it will bring trouble to the cabinet. And the most important thing is that the traffic conditions in the southwest are too poor, and it is difficult to respond in time once there is an accident. Moreover, Xue Yang had an intuition that there should be other forces interfering in Nanzhao at this time, but it was not easy for him to judge much if there was no news from Xuan Yingwei's side, but with this intuition, he still reacted.

Therefore, after informing Xu Ying, Xue Yang immediately changed his plan and led the 3rd Battalion and the Mountain Battalion to march westward at night, preparing to attack Abang and Huichuan or go south from Apang to attack Shanxian Mansion, and besiege the Erhai area from the side.

Xue Yang's move undoubtedly ignited a spark for the complex political struggle in Nanzhao at this time, almost after Zheng Maisi got the news, Long Xun also got the news, if this is not too bad news for Zheng Maisi, then this is not good for Long Xun, the reason why Long Xun was able to muster up the courage to start standing up against Zheng Maisi, it is because he has received foreign aid. When Xue Yang attacked Sichuan, Li Maozhen's general Hu Jingzhang took the Mianzhou defenders south to avoid the hegemony of the Central Plains, and hid in Jianchuan City and other places in Nanzhao. In order to master this force, Long Xun quietly gave up the capital of Nanzhao Kingdom, Yang Tho Baa City.

Since Hu Jingzhang had been in Nanzhao for several years, this time he was very secretive, so that Qin Kong did not notice his traces, but Long Xun's actions still exposed the preparation of the Tiance army. It's just that what Long Xun didn't know was that Hu Jingzhang's military advisor Wen Tao had secretly contacted the Tubo people, and was ready to introduce the Tubo people to fight against the Tiance Army when necessary.

Although the Tiance army did not know that Hu Jingzhang and the Tubo people had begun to emerge, Xue Yang and Chai Jiayi's south and north armies almost locked the north and south ends of the Erhai region, and successfully occupied a favorable situation.

And when these news reached the Chang'an base camp, Hu Xiaosi and Li Xuanqing keenly felt that they were afraid that the history of the Tubo people funding Nanzhao to fight against the Tang Dynasty would be repeated, so almost without thinking, they began to let the General Staff convey an urgent order, ordering Xu Ying to lead the soldiers and horses of the northern front to quickly go south to meet with Xue Yang to deal with emergencies, and told several generals on the front line that all soldiers and horses were under Xue Yang's control, and all means could be taken when necessary.

The order sent by the General Staff surprised these people, and they were very familiar with the history of the Tubo people entering the Nanzhao and the Tang Dynasty, so they immediately notified Li Yang to lead the troops to join Chai Jia when Xu Ying led the troops to the city of Shanxifu, and he chose to wait quietly under the city of Shanyanfu with Xu Ying's brigade.

Although the Tiance army entered the Erhai region, Zheng Maisi was surprised, but the other party's next unmoving troops made him find an opportunity, taking advantage of this rare opportunity, Zheng Maisi decided to have a showdown with Long Xun, first solve the chaos in the country, and then reflexively fight a decisive battle with the Tiance army. In fact, Zheng Maihei's back path has also been thought of, if he can't stop it, he will directly dedicate Long Xun to the Tiance Army. He also understood the thoughts of the Tiance Army, this is a typical way to destroy the Nanzhao Kingdom. So he decided to arrange his retreat before the showdown with Longson, and let his eldest son secretly go to the Western Lands.

After arranging these, Zheng Maisi and Tianqi began to mobilize troops and horses to besiege Dali City in early May of the second year of the Apocalypse, and persuaded more than a dozen middle and senior generals in the standing army of Nanzhao to defect, almost overnight, the situation in Nanzhao suddenly reversed, the standing army was originally the last barrier to protect the dominance of Nanzhao, almost all of them were the imperial forest army in the domestic royal family, but what I didn't expect was that Zheng Maisi actually had a way to pry them into surrendering, and Longxun's power in Dali City collapsed instantly. When Zheng Maisi broke into the palace, Long Xun had little to do to deal with it, so he could only follow Hu Jingzhang's men and horses to escape secretly and go to the western city of Yangtho.

Although he did not capture Long Xun, Zheng Maisi was sure that his arrangements in the west had already played a role, and if Long Xun fled to Yang Tho Baa City, he would only throw himself into the net, so he handed over the task of capturing Long Xun to his son, and he began to attack the Chai Jia Department of the Tiance Army with the integrated Nanzhao army.

The entire Nanzhao coup d'état, Xue Yang and other Tiance troops have been watching from the sidelines, quietly watching Zheng Maisi and Long Xun fight without making a move. And as soon as the coup ended, Zheng Maisi's behavior made Xue Yang frown, Long Xun fled to Yangtho Baa City, Zheng Maisi actually started a war with himself in a hurry, could it be that he had already arranged a backhand? Just when Xue Yang couldn't think clearly, Xuan Yingwei's side finally caught Hu Jingzhang's clues when Long Xun was fleeing, and quickly reported it to Xue Yang. Only then did Xue Yang understand why Long Xun had the courage to turn his face with Zheng Maihei. If Hu Jingzhang intervenes, then Zheng Maisi is estimated to have arranged a backhand in the west.

After thinking about this clearly, Xue Yang asked Qin Kong to quickly go to Yangtho Baa City to inquire about the news of both sides, and focus on the signs of the Tubo people mentioned by the General Staff. He himself immediately waved his army to attack Shanxian Mansion, took this northern gateway to Erhai from the northern front, and completely blocked the northern retreat of Zheng Maihe. At the same time, Chen Yu, who had been wandering around the rainforest for so long, also led the army to drill out and lined up under Profit City. Chai Jia and Li Yang, who were at the forefront of the battle, had already fought with each other, Chai Jia's army began to attack the walls of Jianshui City, and Li Yang led his soldiers and horses to ambush the source troops of Zheng Maihei.

However, these are destined not to become the mainstream of the complex situation in Nanzhao at this time, Long Xun immediately issued the order of the Nanzhao State after arriving in Yangtho City, declaring Zheng Maihei as a traitor, calling on the whole country to encircle and suppress, and at the same time announced the appointment of Hu Jingzhang as the generalissimo of the Nanzhao State Protector, commanding all the soldiers and horses in the country, and announced that he would unite the Tubo people to jointly resist the attack of the Tiance army. When this news reached the east, the Tiance army had not yet begun to move, and Zheng Maisi immediately began to act, taking all the important towns of Taihe, Shihe and Yinsheng between Dali City and Yangtho Baa City, and asked his son to organize people to infiltrate Yangtho City to prepare to assassinate Long Xun.

This series of changes made Xue Yang suddenly calm down, sometimes he was not afraid of too many opponents, but he was afraid that he would not know how many opponents there were. After Xuan Yingwei summarized these news, Xue Yang immediately began to divide his troops, and the main force asked Xu Ying to lead the capture of Huichuan as soon as possible, while he personally led the third battalion and the mountain battalion to prepare for a raid on Yang Tho Baa City day and night, and he wanted to completely break the old capital of the Nanzhao Kingdom and destroy Hu Jingzhang before the arrival of the Tubo people. In order to achieve the suddenness of the battle, Xue Yang didn't bring anything with him when he left, but just reassembled the previous ballista and explosives and took them away and used them as assault fire.

As soon as Xue Yang left, Xu Ying immediately began to pull up the artillery that had been hidden since the beginning of the war, this latest artillery can already fire flowering shells, under the guidance of Li Xuanqing, the artillery manufacturing technology of the Tiance Army successfully avoided the early messy models, and went on the right track.

However, compared with Xu Ying's order to open fire, at this time, Zheng Maihei in Nanzhao announced his ascension to the throne and became the emperor in Dali City, officially abolished the national name of Longxun, changed Nanzhao to Dali, and set the capital of Dali City, which completely ignited the situation in Nanzhao. This scene made Hu Xiaosi, who was in Chang'an, even burst into foul language after receiving Xuan Yingwei's urgent summons, not understanding what kind of support this guy had to rely on when he announced that he was the emperor at this time. But no matter what others do, at least Zheng Maisi has successfully split Nanzhao into two pieces at this time, and the Nanzhao Kingdom is about to fall apart.
