Danxiadu is located in the southernmost part of the Zibai Mountains, the north is the Danxia Ridge of the southern foot of the Zibai Mountains, the Danshi is like Xia, so it is called the Danxia Ridge;

In addition to being one of the most important ferries across the Wantao River in the western region of Dachong, Danxiadu is particularly important because it connects the four regions of Anxi, Beiting, Northwest and Zhongzhou.

When Yongjing was strong, although there were many soldiers and horses in the northwest, there were only a small number of local security soldiers and horses stationed in the northern line, Danxiadu and nearby cities.

Or after the outbreak of the demon tribulation in the thirty-ninth year of Jianxing, millions of demon soldiers entered Zhongzhou through the northeast region, and the three sects in the northwest served as Yongjing, and the main force of the demon soldiers may go around to the south bank of the Wantao River to attack the northwest region, so that Jiang Jin led his troops to enter Danxiadu to build a defensive line.

From Danxiadu to the west, the Wantao River flows more than 60,000 miles in twists and turns, and enters the sea from the northeast foot of the Hengduan Mountains, which is the downstream section of the Wantao River.

The southern part of the lower section of the Wantao River is the territory of the General Mansion of the Anxi Zhu State.

It stands to reason that the lower reaches of the Wantao River are sandwiched between the Northwest Regions and the jurisdiction of the two Zhuguo Generals' Mansions in Anxi, and it is the hinterland of the Chongguo Terran race, so there is no need to worry about being attacked by the demons.

However, after the collapse of the Tashan defense line, the clan lords and clans in Anxi also fled westward in a hurry and retreated into the Hengduan Mountains, and finally under the coercion of the Yue Dynasty, they were forced to reorganize their troops and horses and construct a defense line at the eastern foot of the Hengduan Mountains, but the Wantao River valley from Danxiadu to the west, thirty or forty thousand miles, was completely exposed.

In fact, the defensive pressure faced by the northwest region has doubled, and it is no longer enough to defend Danxia Mountain in the south, but also to defend the 40,000-mile-long section of the Danxia River from the east to the eastern foot of the Hengduan Mountains.

However, in any case, as the connection point of the two defense lines of Wantao River and Zibai Mountain, the status of Danxiadu is undoubtedly crucial.

Chen Hai's first stop on his return from Anze City to the north was also to Danxiadu, where he met Ji Jiangye, Yuan Zhou, Qin Hushan, Cangyu, Zuo Er, Jiang Jin and others.

Fu Shu transmitted, Ji Jiangye, Xi Tongguang, Yuan Zhou, Qin Hushan and others also knew the result of Chen Hai's meeting with the martyr king Qin Hu in Anze City at this time, although the division of the feudal domain was very different from what was originally expected, but the immediate priority was to resolve the differences, so that the north and the south could unite to resist the demons.

Chen Hai also took up the domain in Danxiadu, and officially changed the Northwest Regions and the Beiting Region to Beiling County.

In addition to the five or six million demon soldiers in Xuanyin Valley and Tiancheng Mountain led by the old demon of Ghost Xi on the east side of Zibai Mountain, the old demon of Xinshan also led four million demon soldiers of the Reincarnation Hall from Yongjing to the north and marched towards Danxiadu, and the pressure north of Tianluo Valley was the least.

As soon as the war broke out, the matter of sealing the domain was naturally simple, even if it was Chen Hai's Beiling County King Seal, it was only re-engraved by using the previous seal of the general of the Northwest Domain Pillar State.

The seals of the other princes and generals were also engraved by Chen Hai, and then reported to Anze City in the rune book; under the raging demon calamity, the Great Chong Emperor's embarrassment reached such an extent, and it can also be seen that the danger of the Great Chong Human Race.

Crossing the Wantao River, there is no steep mountain to block the demons from the south, so Danxiadu is really a place that Beiling must defend.

According to the policy of dividing the feudal kingdom implemented by Emperor Lie, the royal capital of Beiling County should be built within Chen Hai's direct fiefdom, so that Chen Hai can also govern the vast territory of the county at the same time when he governs the directly subordinate fiefdoms, that is to say, the king needs to be arranged within four or five thousand miles between Mozhang Ridge and Tianluo Valley, and at the same time, including a complete set of military, administrative and jurisdictional systems, all need to be established in the royal capital, and then it is possible to effectively govern the east to Murowei Mountain, west to the Falling Star Sea, south to Wantao River, north to Tianluo Valley, including Yanzhou, The Blood Refining Field, the vast territory of the two small thousand heaven domains, and more than six billion mortal people.

However, the center of gravity of the imminent outbreak of the Great War is in the southeast, not on the northern front.

On the one hand, Chen Hai made Beiling City the royal capital, and made Zuo Er serve as the royal capital and Yuan Zhou served as the governor of Beizhen, jointly leading the military, political and defensive affairs from Mozhangling to Tianluo Valley and Yanzhou.

In addition to Zuo Er and Yuan Zhou, only Lu Shaoshang, Sha Tianhe, Yu Cang and other ten heavenly true monarchs were left on the northern line.

Dong Ning and Su Aya returned to Yanzhou with Yang Qiao'er, responsible for the military and political affairs of Yanzhou; at this time, Yanzhou, where the strong people of the Heavenly Rank Realm and the Heavenly Demon Realm could not enter, was naturally the safest, and the Tianying School Palace had also been temporarily moved into Yanzhou, and merged with the Tianji School Palace and the Shenling Mountain School Palace near Montenegro.

There is no extra heaven and earth protection array, which is also to prevent the demon powerhouse of the demon clan from suddenly sneaking into the hinterland of the Beiling County and killing indiscriminately, severely damaging the reserve force of the Beiling County - at this time, only the army is not afraid of the surprise attack of the demon powerhouse.

In addition, Chen Hai discussed with everyone and decided to build a small city called Yanqing north of Danxiadu and west of Danxialing, and renamed Yanqing as Lingzhou as the station of Nanzhen for expansion.

Chen Hai personally led the governor of Nanzhen, and commanded the garrison of the two defense lines of Zibai Mountain and Wantao River.

Fu Siyuan served as the envoy of the Heavenly Council who controlled the affairs of the sect, Ji Jiangye served as the envoy of the Chongzheng Yuan who acted for the affairs of the county government and the Hou State, and Qin Hushan and Xi Tongguang served as the left and right lieutenants who assisted in the defense of military affairs, plus Yuan Zhou, it can be regarded as the five giants of Beiling County except for Chen Hai - Zuo Er and Cangyu are more like Chen Hai's retainers, in addition to assisting Chen Hai in handling the affairs of the feudal province and taking charge of the guards and soldiers, the authority in the county is not as good as Fu Siyuan, Qin Hushan, Xi Tongguang, Yuan Zhou, and Ji Jiangye.

This is also the appointment arrangement of Emperor Qin Ran.

The next step is the adjustment of the soldiers and horses.

The original part of the Beiling Army, and then recruited generals from the Beiting Defense Army in the west and the children of the clan in the west, and gathered 1.5 million horses and horses to be incorporated into the Beizhen Army.

Under Beizhen, there is no longer a capital protectorate, and it is directly connected to the northern defense north of Pingma Mountain.

During the period when Chen Hai was heading south, the advance army of Long Xiang and part of the Beiling army had already moved south under the command of Xie Jueyuan, Miao Fengshan, Dong Liang, Cang Yu, Jiang Jin, Lei Yangzi and others, and had already assembled in Danxiadu to prepare to meet the demon soldiers from Yongjing.

Nanzhen will set up five capital protection mansions, divided into three passes of Zibai Mountain and form two defensive support points under the Wantao River, which is mainly composed of the original team of Zixu Sect, Wanxian Mountain, Yuanyang Sect, and Xuanhuang Palace, each of which is composed of one million soldiers and horses, which are controlled by Xi Tongguang and Qin Hushan.

The soldiers and horses of the three sects such as the Tianhe Sect, as well as the part of the Beiling Army, plus an elite general drawn from the four sects of Zixu Sect, Wanxian Mountain, Yuanyang Sect, and Xuanhuang Palace, will form a Nanzhen Army with a scale of three million men and horses under the direct control of Chen Hai.

At the same time, Chen Hai also transferred Qin Qian, Fu Shaoqun and other generals into the 300,000-strong Ma Longxiang army as his royal capital forbidden camp army.

All the adjustments of men and horses are on the basis of the existing one, and it is possible to reduce interference, so that in addition to the local defense soldiers and horses of the hinterland counties and counties, Chen Hai can directly mobilize the soldiers and horses on various fronts, including the Nanzhen Army, the Beizhen Army, and the Wudu Protectorate and the Longxiang Army under the jurisdiction of Nanzhen, totaling 9.8 million.

Excluding the elite reinforcements directly sent by Tiannan and Yue, as far as the old forces of Dachong are concerned, at this time, the four million soldiers and horses of Emperor Qin Ran in Anze have some combat effectiveness, and the three major counties of Nanli, Nanzhao and Anxi can nominally each have three or four million soldiers and horses, but it is really difficult to say how much combat power can be left.

The clan of the Nanli clan fled into Yunling, and the mortal people under their rule were less than 500 million, how could they supply 8 million soldiers and horses, including the Xuanyuan Army and the Nanli Defense Army stationed in Anze City?

In the same way, the Southern Zhao Zhuzong also gave up a large area of land and fled into Minshan, at this time there were only less than one billion rulers in the southwest of Minshan, and it was also difficult to supply four or five million elite generals to carry out a long-term and difficult war against demons.

The Anxi Sects once wanted to reduce their troops to about one million, because the resources in the hands of the Anxi Sects could only barely maintain such a large-scale military garrison.

Comparatively speaking, the Beiling County accepted two or three billion human races to flee to the west of Zibai Mountain, even if hundreds of millions of people died of famine and disease on the way, it also made the mortal people under the jurisdiction of the Beiling County at this time, including Yanzhou, more than six billion.

In fact, it may also be said that the last part of Da Chong's remaining vitality is mainly in Beiling County, but only in this way can it support the war consumption of tens of millions of elite soldiers and horses.

Chen Hai did not want to retreat to the passive defense behind the Wanyuan River, and after the affairs of the vassal country were sorted out, he directly led Long Xiang's personal guard army to cross the Wantao River and arrived at Taihua Mountain, which was more than 3,000 miles southeast of Danxiadu.

Taihua Mountain can only be regarded as the remaining vein of Zibai Mountain on the south bank of the Wantao River, the mountain range stretches for more than 2,000 miles, like a long and narrow screen, across the south bank of the Wantao River, blocking before Danxiadu.

Although the terrain of Taihua Mountain is quite dangerous, there are Pingchuan on the left and right and south back, and it is impossible to cut off the pace of the demon soldiers moving west or north.

The three sects did not build a defense line in Taihua Mountain, because the Terran Houma was not used to it before, and they did not like to engage in field battles with the main force of the demon soldiers with heavy casualties, and they preferred to use the danger of mountains and rivers to block the attack path of the demon soldiers, so there was no need to fight on Taihua Mountain, and the defenders would easily be surrounded and killed by the demon soldiers.

Chen Hai's tactics are far more active than the tradition, and he is not afraid of field battles with the demons, at this time Chen Hai pushed the defense line to Taihua Mountain, and the main force of the demon soldiers will not easily expose the flanks, and casually bypass Taihua Mountain to attack other cities or fortifications of the Beiling Terran - Taihua Mountain will actually become a junction point that is more advantageous than Danxiadu's geographical location and can take into account the defense line of Zibai Mountain and Wantao River.

Chen Hai decided to transfer the 300,000 Longxiang guards and the 2 million Nanzhen troops to the Taihua Mountain tectonic defense support point, and the old demon of Xinshan led the main force of the Demon Soldiers of the Reincarnation Hall who devoured blood and food in Yongjing and greatly increased their strength, which was less than nine thousand miles away from Taihua Mountain.

In the spring of the forty-fifth year of Jianxing, which was also the first year of Emperor Lie, Chen Hai stood on the sea of clouds in Taihua Mountain, and he could already directly feel the monstrous demons coming at this time.

Chen Hai deployed the Gengyang Golden Thunder Array and the two Ten Thousand Immortal Demon Arrays in Taihua Mountain, and two million and three hundred thousand elites and more than sixty thousand heavenly chariots were also stationed in Taihua Mountain......

Obviously, the demon soldiers will not directly come over to hit this iron plate, and their main force will stop in the Yin Soul Ridge four thousand miles away to the south and no longer move forward, in addition to constantly transporting the dead bones from the rear to pile up the ten thousand demon dry bones array, the hundreds of thousands of elites of the demon soldiers will turn straight and go west.

The demons obviously still want to attract the Nanzhen army from the strong defense line guarded by the Heaven and Earth Great Array for field battles.

At this time, the demon clan obviously knew very well that the heavenly chariot was galloping in the wilderness without galloping roads and bumps, and the damage rate was extremely high, and only the long-distance movement battle between the rugged barren mountains could give full play to the physical advantages of the demon soldiers and demon generals.

If Chen Hai ignores the demon race, the main force of the demon soldiers of the Reincarnation Hall moves westward, which can not only devour the residual habitat of the human race west of the Hengduan Mountain Range, but also go to the lower reaches of the Wantao River, divide a small group of soldiers and horses to cross the Wantao River, and enter the territory of Beiling to attack and kill civilians.

Even if you don't use the existence of the Demon Lord and the Demon Marquis, and lurk in the depths of tens of thousands of miles to bloody torture and kill, a small group of demon schools and demon generals can infiltrate across the Wantao River, and they can also penetrate thousands of miles beyond the Wantao River, killing them like a river of blood.

Within a thousand miles of depth, it is very difficult to intercept a small group of demon elite combat power.

Nearly 20 billion mortals in the Haidong Continent died in the Demon Tribulation, which made the Demon Clan use hundreds of millions of human corpses to pile up hundreds of demon cultivation lands and more than a dozen Ten Thousand Demon Dry Bone Arrays in Zhongzhou, Beiting, and the Eastern Regions, which made the Demon Clan's sword go off the rails, and it was actually faster than the human clan sect to cultivate the backbone of the Demon School and the Demon General.

And Chongguo's several devastating defeats have sharply reduced the elite combat power above the Ming Hole and Dao Dan realms, and if the demon clan uses the elite combat power above the demon school to infiltrate the territory of Beiling, Beiling will be extremely embarrassed to deal with it......

However, if it is delayed until the next winter, when the Wantao River and the Nuchuan River are completely frozen, the main force of the demon clan can even suddenly pass through the defense line of the Wantao River and enter the hinterland of Beiling to fight without any obstacles.

Otherwise, the four or five billion mortals who retreated to the north of the Wantao River and west of Zibai Mountain at this time don't know how many will be devoured alive by the demons......
