The meeting of Nashi Town was of far-reaching significance to the development of the entire northern part of the Tang Empire, when the Ministry of Communications dispatched manpower to conduct a comprehensive exploration in the area south of Zhenyi Yin Mountain, and it took more than a month to complete the exploration of a railway line from Lingzhou to Jizhou in the east, which was thousands of miles long, and then compiled a plan and submitted it to the Ministry of Communications.

However, at this time, Wu Zuodong followed Li Xuanqing and his wife and Cen Tianshi to return to Chang'an, and all the energy of the Ministry of Communications was spent on the dredging of the canal and the construction of the Changjin Line.

"Sir, you go back and discuss with Tianxiang, pull back the captives from Nanzhao and send them to Fengzhou, so that part of the manpower problem can be solved, after the canal is dredged, except for the laborers who have expired, everyone else will also be sent to Fengzhou and other places, and the manpower of the first phase of construction is almost enough." Li Xuanqing couldn't help but smile at Wu Zuodong's crying face: "Don't be sad, Qiaoxi and I didn't feel anything after we bet the last property in our hands to Qian Zhuang, why are you even more unbearable than us?" ”

Li Xuanqing's words made everyone laugh, and Cen Tianshi also followed: "After you go back, Qi Hong, you will immediately rush to Nanzhao's side and bring back all the treasury of Nanzhao to me, not a single copper will be left behind, and tell Xue Yang and Chen Yu that the people who can be captured should be captured as much as possible, and I will kill them all if you don't have fun." Now the empire needs manpower, it needs endless manpower, if they can't get more than 100,000 prisoners, I will definitely cut off 30% of next year's military spending. ”

Cen Tianshi's vicious words made everyone laugh, and when he said this, Li Xuanqing remembered what he commanded: "Go back and remember to ask the Ministry of Land and Resources to send a large team of people to Nanzhao and Qiqi and Guangxi to have a look, if I estimate that there are a lot of silver mines over there, it will not be worse than Sichuan." Before Li Xuanqing's words were finished, Cen Tianshi directly asked his guards to return to Chang'an as soon as possible, and informed the Ministry of Land and Resources to let them act quickly. In fact, this time the Ministry of Land and Resources has gained a lot, originally there were a lot of silver mines in Nanzhao Kingdom, and all of them were taken over by them and the Logistics Department, and by the end of the year, they actually added millions of taels of silver, which was also an additional income.

After Li Xuanqing and his entourage returned to Chang'an, Cen Tianshi seized the time to arrange funds and manpower to explore the railway, and Qiaoxi took Mu Chen to meet Wu Zuodong to go to Qianzhuang to go through the formalities, and Li Xuanqing only received a detailed battle report from Xu Tianxiang about Nanzhao at this time.

"Xue Yang's side really defeated the Tubo people in Nongdong City? It seems that we will have to fight with them in Nanzhao. Li Xuanqing took the battle report and said in a deep voice: "That Longxun was caught?" Let Xuan Yingwei's people go to him and ask him to atone for his sins with silver, how can he say that he is the lord of a country, he can be worth more than one hundred thousand taels, right? Let Xuan Yingwei do it, the cabinet has been short of money recently, and Qiaoxi has mortgaged all the income of the industrial group this year to the money bank in exchange for a railway loan. ”

What Li Xuanqing didn't expect was that his unintentional joke really made Xu Tianxiang spread to the front line, and this time the rich and aristocratic groups in the entire Nanzhao country suffered, and those Tiance soldiers heard that the queen mother had taken the industrial group for the development of the empire, and their eyes were immediately red, didn't they come to this Nanzhao country to fight for the unity and prosperity of the empire? Why is there no money for the queen? If you don't say anything, go directly to those rich people, and let them take out all the money for me, how can you say that you can't let the queen sell the dowry? Therefore, the Tiance army, which originally took the Erhai area and should be renovated to deal with the Tubo people, suddenly dispersed again, almost those nobles and rich people who did not have time to escape were wiped out, as long as they fought against the Tiance army before or did illegal things, all the property was confiscated, and a part of the grain and land was distributed to the poor people on the spot, and most of the remaining gold and silver treasures were all pulled back, and the logistics department was sent back to the Chang'an base camp, and even the mansion of Zheng Maisi in Dali City was pulled out by this gang of guys to be sold.

This action lasted until mid-June of the second year of the Apocalypse, when Xue Yang's order reached Dali City, ordering Chai Jia and Li Yang to immediately lead the main force to attack along Longhe and other places to join them in Yangtho City, prepare to deal with the second attack of the Tubo, and divide their troops to pursue Zheng Maisi and Hu Jingzhang. When Li Yang and Chai Jia heard the news, they left a battalion to garrison Dali City and other places to wait for the National Guard to receive them, and the other 60,000 people immediately left Longhe City and went to the west.

At this time, the main force of Chen Yu's corps on the southern front continued to march west towards Blind Nai Road after capturing Profit City, and the other went south under his personal command to confront the Ten Black Tooth Divisions, preparing to completely take down the southern forces in Nanzhao, so as to open up the land connection between the southern part of Nanzhao and the Jiaozhou region. Under the guidance of this strategy, the remaining three battalions in Jiaozhou also began to set off directly from Yanzhou, preparing to copy Wendancheng, the largest town in the south.

In the rainforest area, the Chen Yu Corps, which is more and more comfortable to fight, braved the rain in the middle of June of the second year of the Apocalypse and launched a fierce battle with 30,000 people of the Black Tooth Ten Division in the mountains more than 100 miles south of the profit city, originally Chen Yu was also worried that the rain would affect the efficiency of the rifle, but the flint used in the musket designed by Li Xuanqing was ignited, and the rainproof cap was specially installed in order to be waterproof, so it was almost one-sided to knock the army of the Black Tooth Ten Divisions to the ground, and more than 10,000 of the 30,000 people were captured in addition to the battle dead, and the other escaped personnel drilled into the depths of the mountain and turned into birds and beasts.

After this battle, the living forces of the Ten Black Tooth Divisions were wiped out, and the remaining men and horses continued to retreat south under the leadership of their leader, the Black Tooth King, in an attempt to rely on the rainforest and terrain to make it difficult for the Tiance army to retreat. However, at this time, Chen Yu's energy was no longer on these people, except for sending a battalion to follow these people far away to maintain pressure, the other manpower quickly waved his army north to prepare to participate in the battle on Xue Yang's side.

At this time, Xu Ying led three battalions of troops to Lishui City, preparing to pursue Hu Jingzhang and Zheng Maihei, while Li Yang led his headquarters to recover other cities in Nanzhao, with Long Xun, the lord of the country, almost all the cities in the west of Nanzhao were taken in just ten days. However, Xue Yang did not send troops to garrison for the time being, but just surrendered, and the main force of 70,000 men and horses set off from Yangtho Baa City to Tieqiao City in the north of Jianchuan near the border of Tibet, preparing to meet the Tibetan army there. At this time, the latest news also came from Xuanyingwei's side, the Tubo army was already on the way from Ma'ercheng, and this time there were 100,000 troops, which should be the last army of the Tami royal family.

After Xue Yang arrived at Tieqiao City, he began to ask Xuanyingwei to explore their marching route, and arranged for Li Yang to renovate his position on the border to prepare for the battle, but what made him a little embarrassed was that although Tieqiao City was an important town guarding the border between the two places, it was obvious that the Tubo people had another route to enter Nanzhao, that is, to enter Xiangcheng County from the east of Tieqiao City, and Xuanyingwei was not sure how they should go.

If you want to divide the troops, then even if the opponent's 100,000 iron cavalry has new weapons to help, I am afraid that it will be difficult to block the opponent, but if you don't divide the troops, if you miscalculate, then wouldn't you let the other party enter the territory of Nanzhao? For Xue Yang, who already regarded Nanzhao as the territory of the Tang Empire, he would never allow the imperial troops to run freely on his own territory.

So after thinking about it, Xue Yang still decided that he couldn't wait for the rabbit, he had to take the initiative to attack, and he wanted to use the strong strength of the 70,000 army in his hand to penetrate deep into the opponent's territory and force the other party to fight with him, so as to achieve the goal of solving the opponent in a war. Thinking of this, Xue Yang began to study several routes from Ma'er City to the south, and invited Li Yang and Li Shenfu to discuss countermeasures.

Xue Yang immediately asked the herald to tell Chen Yu to let him lead his troops into Xiangcheng County, from where he entered the territory of Tubo and drove the Tubo army to the side of Tieqiao City, in order to achieve the purpose of starting a final battle with the other party in Tieqiao City. With Chen Yu's support, Xue Yang put down his mind and built a standard infantry position outside Tieqiao City, and the 70,000 army was divided into three parts along the fork in the road formed by a small hill, so that he could deal with the enemy coming from the north and northeast at any time, in order to emphasize the firepower, Li Shenfu even commanded more than 20 artillery pieces to be moved directly to the top of the mountain, where a perfect artillery position was constructed, according to this height enough to radiate the entire battlefield.

After arranging these, Xue Yang once again gave Chen Yu, who had already entered Xiangcheng County, to ask him to seize your time to speed up, and if he encountered an opponent on the way, he would fight and retreat towards his side, attract the opponent to Tieqiao City, and then outflank the opponent in a reverse roundabout.

"Marshal, if we finish this battle, the war on the southern front is basically over, right?" Xue Yang stood at the head of Tieqiao City, looking at the rolling mountains in the north, not knowing what he was thinking, Li Yang came over behind him and sighed: "Back then, General Hu asked me to study at the Military Academy, I never thought that one day in the future, I would be able to lead the army to this foreign country, and I didn't expect that the emperor would really be able to realize the promise of the unification of the Tang Dynasty." ”

Xue Yang also nodded and smiled: "You are luckier than me, I was just an unemployed vagrant with no livelihood before I joined the Tiance Army, and I ate the last meal without the next meal, after joining the Tiance Army, in addition to studying at the Military Academy, I joined General Li's army, and after the First Battle of Chang'an, I followed Wang Shuai to join the third battalion today, it really sounds like a dream." ”

"Qiyu Dashuai, fifty miles outside the city, I found traces of the Tubo people." The two of them were originally going to say something, and the report of Xuan Yingwei behind them pulled the two back to reality. "It seems that Chen Shuai's side did not intercept the Tubo people, you immediately send a message to let Chen Shuai lead his troops to the north of the Tubo people, and we will attack back and forth to completely destroy the opponent." After the Xuanying Wei messenger left, Xue Yang and Li Yang quickly left the city and came to the position outside the city.

At this time, the Tubo people were already approaching the position of the Tiance army, and Li Yang's troops were directly in front of the Tubo people, so he went directly to the front line to command the troops, and Xue Yang directly climbed to the top of the mountain and came to the artillery position.

"Captain Li, can your artillery hit five miles away?" Xue Yang saw that the Tubo people had begun to form a team in the open space five miles away from the Tiance Army's position, and immediately pointed to the opposite side and asked.

Captain Li was the captain of the artillery battalion of the group army, but because Xue Yang's southern front group army was split several times, there were only twenty artillery pieces gathered at this time, which were arranged in a fan-shaped division on the top of the mountain. At this time, he heard Xue Yang asking, came over and saluted and shook his head: "Marshal Qiqi, the maximum range of the artillery battalion is only three miles, and the best killing range should be between two and three miles, so it cannot be launched for the time being." ”

"It's okay, get ready, wait for the order to launch." Xue Yang originally just asked casually, but when he heard this, he nodded and walked to the front to pick up the latest distribution of the Thousand Miles Realm to observe his opponent's every move. The production process of this Thousand Miles Realm is actually very simple, although it is time-consuming and laborious to polish a qualified lens after the glass is brought over by Li Xuanqing, it is still possible to distribute this kind of monocular Thousand Miles Realm to senior generals, and today's generals at the level of the Tiance military camp basically have one each.

"This group of Tubo people is much more shrewd than before, and they also know how to use the zigzag formation to attack." Xue Yang looked at it for a while and thought for a while, the zigzag formation basically will not be a big problem for the attacker's side, and when necessary, he can quickly use the two positions in the rear to support the forward troops in front, and if the battle is unfavorable, it can also play the effect of covering each other's retreat.

However, the Tubo army uses a zigzag formation, in fact, if the Tiance army is really elegant, it can be regarded as a zigzag formation, but the Tiance army has used the trenches to fight field battles under the advocacy of Li Xuanqing, and the half-man-high trenches allow the soldiers of the Tiance army to lie in the trenches and shoot with guns.

Xue Yang's side was waiting for the Tubo people to attack, but Chen Yu's side began to be anxious, because after they went out of the border, they took the wrong road and delayed the time, so that the Tubo people began to attack, and they were still circling in the mountains, if it wasn't for the messenger of Xuan Yingwei to come to report, they would really miss this battle.

However, after getting the Xuan Ying Wei to lead the way, Chen Yu's speed also increased suddenly, because he only needed to go straight to the north of the opponent to intercept, so he didn't need too many tactical moves, and as time passed, they had already heard the rumbling cannon sound from the front, which undoubtedly reminded Chen Yu that he was close to the battlefield, so Chen Yu began to let the troops hurry up and enter the northern mountainous areas of the Tubo people, looking for favorable terrain to ambush on various roads, intercepting the rout of the Tubo people, and he himself took a battalion of troops to move forward, Be prepared to attack at critical times to achieve the tactical effect of flanking back and forth.

However, when Chen Yu came to the front line, he found that the 100,000 army of the Tubo people and hundreds of thousands of horses' hooves raised dust and rushed towards Tieqiao City, which immediately made him a little worried about Xue Yang. However, the sound of artillery shells exploding immediately gave him confidence and began to think about planning a fighter.
