At the end of August, the Taiwei Mansion officially issued a document, worrying about the severe border troubles of Tianshui County, and the monsters became increasingly rampant. Chen Hai ordered the Longxiang Camp to move to Hengshan in the north of Tianshui County to assist local military equipment to prevent border troubles.

The Beijing camp army usually controls the border, but this time Chen Hai led his troops to move to Hengshan, and did not give him the title of senior general who could control the local troops. After arriving in Hengshan, he still had to accept the control of Tianshui County Massacre and the General Mansion of the County Commander General. In fact, the Jingjun clans and Yanran Army did not want to see Chen Hai suddenly gain power, and they did not expect it.

The marching route of Longxiang Camp was strictly restricted by the Taiwei Mansion, and there was no intention to let Chen Hai lead his troops from the capital to cross Qintong Mountain and advance westward.

Borrowing from Jingji was originally the fastest passage, but Ying Wang and Taiwei Tu Que were really worried that Longxiang Camp would enter Jingji area or Qintong Mountain. Longxiang Camp stopped halfway and did not leave, so they would be blind.

The route formulated by the Taiwei Mansion for the 30,000 troops of Longxiang Camp was to borrow from Yongjun, cross from Zhanmaling, north of Qintong Mountains, and enter the northern part of Tianshui County.

Although the terrain of Zhanmaling is not as steep as the many ridges on the northern foot of the Qintong Mountains, it is also full of peaks of four or five thousand meters. The Yangchan Valley Road is extremely narrow and steep, and it is an important barrier for Yanzhou to resist the evil and man tribes in the northwest direction.

The 30,000 cavalrymen in Longxiang Camp borrowed the route from Zhanmaling. One reason was that the journey was difficult, and it was also seven or eight thousand miles away, which might take twice as much time than borrowed from Yanjing.

Secondly, after crossing Zhanma Ridge, before arriving at the Hengshan defense line in the north of Tianshui County, there are more than a thousand miles of wasteland, which is an area where the demons often enter, especially after the demons and demons enter the autumn, they will be quite active in this area.

Longxiang Camp entered the wasteland between Zhanma Ridge and Hengshan defense line, and it was almost impossible to escape the harassment of the demon barbarians. He also had to pray that there would be no main force of the demon barbarian gathering nearby, otherwise he might face a disaster of overthrow.

The route of the Beijing camp army's defense was designated by the Taiwei Mansion, which was also a rule to prevent the generals who were in charge of the army and had different ambitions.

However, at this time, the two wind flame airships from Tianji Academy had been manufactured in Liquan and in the workshop at the foot of Juquanling Mountain, and this time it could come in handy.

Chen Haixian, Huang Shuang, Qi Hanjiang, Han Wendang, Sun Gan, Han Jian and others first led the Huwei camp to take two flaming airships, and the military commander Fang Xiyan, under the escort of more than a hundred battle birds, flew directly from the valley between Qintong Mountain and Zhanmaling, entered the northern part of Tianshui County in advance, and took over the defense of Hengshanxi wings.

The main force of Longxiang Camp, except for 20,000 combat cavalry and lightweight combat equipment that is easy to transfer, was handed over to the local area to take over. Under the leadership of Le Yi, Wu Meng, Zhou Jun and others, they slowly borrowed from Jiyang County and Yong County and gathered at the eastern foot of Zhanmaling in advance.

At this time, the superiority of the Fengyan Airship is fully demonstrated.

A large wind flame airship with a load of 200,000 kilograms can transport thousands of light armored soldiers at one time, and the transportation efficiency is extremely high, and it can almost ignore the obstacles of the terrain.

Although the Fengyan airship should not fly too high, it is the limit to 5,000 meters. No matter how high it is, it will become extremely unstable when facing the bitter wind. The airbag sewn with animal skins cannot withstand the sharp and sharp wind like sword energy.

But not to mention Zhanmaling, even the numerous ridges on the northern foot of Qintong Mountain have enough space between the peaks that are often tens of thousands of meters to allow Fengyan airship to pass through.

The straight-line distance from Hengshan to Lianshui is only more than 4,000 miles. Two days and two nights of Fengyan Airship is enough, and you can stop and take a breath in the middle. However, if you don’t use Fengyan Airship, thousands of elite soldiers, even if you ride a green cunning horse that can travel thousands of miles a day, you will be able to detour from the mountain valley roads, and it will take more than half a month to get from Lianshui to Hengshan.

There were two Fengyan airships. After receiving the official transfer order from the Taiwei Mansion, one thousand sharp soldiers of the Longxiang Camp Huwei Battalion and some military officers such as Sun Gan, along with their soldiers and hundreds of heavenly war crossbows, entered Hengshan City three days later.

The speed was so fast that the garrisons in front of Hengshan City were dumbfounded, thinking that the enemy was raiding, because they received a letter from the Taiwei Mansion the day before.

Fortunately, Wu Jinglin and Wu Yunqiao accompanied Chen Hai; otherwise, Chen Hai would not be able to take over the defense of Hengshan City from the previous garrison, and no one could believe that they would come so quickly.

Although the two flaming airships are expensive, no matter how expensive it is, they are much lower than the taming of three or four hundred black-feathered giant eagles.

Moreover, the incubation and taming of the black-feathered giant vulture is not easy. Hexi's strength can be said to have developed to its peak at this time, but at this time, there are less than one hundred new black-feathered giant vultures that can be added to the army every year.

Next, the two Fengyan airships will continue to be put into use, continuously transporting the generals and soldiers and weapons of the Longxiang Camp of the Suwei Army to Hengshui. In addition, the generals and soldiers of the Longxiang Camp were also led by Le Yi and other generals, and at the same time, they drove west from Lianshui. The entire migration process is expected to be one-third shorter than the passage from Jingji and Qintongguan.

The biggest problem is that the transfer of more than 20,000 war horses is the most troublesome. After all, war horses are too large in size and weight.

Longxiang Camp acquired the remnants of the Heiyan Army. The 20,000 war horses retained after the reorganization were all good varieties. However, these war horses entered high altitudes by airships, but no one was as honest as they had to install specific and sturdy horse ties to squeeze out space and load, which would be extremely troublesome in any case.

The final plan was to hand over more than 15,000 war horses to the caravan of the Tianji Academy to take over, enter the Jingji area from Wusheng Pass, and pass through Qintong Pass to Hengshan.

The remaining 5,000 excellent combat cavalry were organized by Le Yi and passed quickly from Zhanmaling. Other generals and soldiers arranged for Fengyan airships to receive them one after another during the process of carrying out the army in the west.

By mid-September, General Wu Cheng, the commander of Tianshui County, rushed to Hengshan to meet Chen Hai, eight thousand warriors had already entered Hengshan City, Longxiang Camp, the guards.

Wu Cheng and Wu En, the contemporary Wu clan leader, were cousins, both of whom were in the middle stage of the Daodan realm. They were in Tianshui County and Huayang Sect. They were in the same position as Zhou Zhong and the old Zhou clan leader, Qu Xiyuan, and Liao Yunkui, who was from a poor family and had a weak clan power, were also known as the Six Lords of Huayang Sect.

Because the three tribes of Wu, Zhou and Qu have their own specialties in Tianshui County and Huayang Sect, no tribe can suppress the other two tribes, the three tribes have taken turns to serve as the important positions of county maids, generals of the commanders and generals of Tianshui County in the past century.

At this time, the host of Tianshui County was Qu Xiyuan, the head of the Qu family, and the general of the commander was Wu Cheng of the Wu family.

Chen Hai led his troops to move to Hengshan City, nominally accepting the control of Qu Xiyuan and Wu Cheng, and at the same time, he also knew about the affairs of Hengshan Prefecture. As long as he did not transfer from Tianshui County, he would be considered the third person in Tianshui County. However, his defense zone was in Hengshan City and the vast battlefield where the evil barbarians could fight against the evil barbarians north of Hengshan City. He could not reach his hand to Tianshui County, and naturally he could not interfere in the military and political affairs within Tianshui County.

Every winter, the northern wastelands are covered with ice and snow, so they will go south to hunt. Therefore, every October, it is the most tense moment in the northern part of Tianshui County.

Although the clans of Beijing County intend to make things difficult for Longxiang Camp, and although the tribes of Tianshui County have their own thoughts, defending the Hengshan defense line is the bottom line that everyone must adhere to. Therefore, Wu Cheng was also worried that the Longxiang Camp would not be able to move in time, and the Longxiang Camp had only more than 30,000 generals and soldiers. He was also worried that the Longxiang Camp's strength was limited and that the eastern area of ​​the Hengshan defense line could not be defended.

However, in just half a month, the eight thousand soldiers of Longxiang Camp entered Hengshan City. Wu Cheng was also quite shocked. He had seen Fengyan Airship on the spot and looked even more solemn.

These are only two Fengxiang airships, which can transport 8,000 elite soldiers from four or five thousand miles away from the Guanshan River to Hengshan within half a month. What if Longxiang Camp had twenty Fengxiang airships?

From then on, which one's rear and hinterland are still absolutely safe?

However, the Tianji Academy did not secretly promote the creation of Fengyan Airship. As long as any county tribe is willing to pay, it cannot be said to be harsh. It has been changed from Tianji Academy to the Picture Scroll. For convenience, the Miao and Yue clans directly established Fengyan Airship casting workshop in Liquan after purchasing Fengyan Airship Scroll, and even hired familiar craftsmen from Tianji Academy. Therefore, no one can have any position on this matter to blame Chen Hai or Tianji Academy.

It’s just that everyone must continue to adapt to the new war mode in the future, which is also a headache.

From between Taiwei Mountain and Qin Tong, the terrain was low and a gap of nearly a thousand miles was formed, becoming the main passage for the demons and barbarian tribes to attack the northwest.

This passage goes to Huayang Ridge in the south of Tianshui County, without major terrain obstacles, and can block the invasion of the demon barbarians from the south.

To alleviate the pressure of defense, Tianshui County built the defense line on the south side of the entire gap. There was still a low mountain Hengshan Mountain with only about five or six hundred highs. More than a dozen defense villages were built to resist the invasion of monsters and barbarians.

Later, Chen Hai led Longxiang Camp to be responsible for the eastern area of ​​the Hengshan defense line. This area is close to the northwest foot of Qintong Mountain, crossing the numerous ridges on the northwest foot of Qintong Mountain, and is only a thousand miles away from Liquan. The Tong River flows out from the dangerous valleys and valleys on the western foot of Qintong Mountain, flows from the front of Hengshan City, and goes to the north, gathering the rivers from the source of Taiwei Mountain and Zhanmaling, and flowing northward, flowing northward all the way to the northward, flowing into the vast vast sea of ​​the northern where the Yaoman tribes gather.

It is severely cold in winter, and rivers flowing from the northern foot of Taiwei Mountain to the north will completely freeze in winter. However, in the beginning of spring, the earth will warm up and the ice will melt, and the land along the coast will be washed away by the flooding of wanton floods, forming a natural barrier to prevent the demon barbarians from invading the south. When the cold season comes again, the floodplain of the northern wasteland will be frozen again, which is a good opportunity for the demon barbarians to invade the south.

The western area of ​​the Hengshan defense line will be defended by Tianshui County in the future. Because Longxiang Camp joined the defense line, Tianshui County can draw 100,000 troops from the Hengshan defense line at this time and move it to the west of Huayangling to guard against the abnormal movements that the Hexi Army may take against Tianshui County - this is also the main reason why Tianshui County asked for help from Yanjing.

In the northeast of the Hengshan Defense Line of Tianshui County, there is the Zhanmaling Defense Line of Yong County, and in the northwest direction is the Duanlongling Camp located on the northeast foot of Taiwei Mountain in Hexi. It can form huge jaws from the left and right wings, restricting the demon barbarians from rising from this gap to invade the south, which greatly alleviates the defense pressure of Tianshui County.

The only problem is that from the Hengshan defense line to the north, almost thousands of miles of fertile soil was abandoned and turned into a vast grassland, and flooded again after spring.

This is also the key reason why Tianshui County is extremely weak and the tribes have no ambitions.

Tianshui County was originally split from Qinshan County, but because the land that was thousands of miles north of Hengshan Mountain was voluntarily abandoned, the land was nearly half less than that of other counties. How could it be not weak?
