Tashan Mountain West out of the Murowei Mountains, to the east until it stretches for thousands of miles, is a hilly belt in the central region of the Songliao Plain, the mountain is not precipitous, but at that time the gateway to the Zhongzhou Plain Dayan Mountain was occupied by the elite main force of the demons, and this place is the narrowest mouth of the Songliao Plain, Jiang Yin finally decided to lead the Qinwang army into the Tashan organization defense line, and choke the Rakshasa Demon Clan to continue to advance to the Zhongzhou Plain.

Although the original Qinwang army had limited troops and horses, and could not completely block the Songliao Plain, it also successfully curbed a large number of demons from continuing to advance unscrupulously towards the hinterland of Dachong.

Jiang Yin's big tent is located in the Dingtao Pass of the Absolute Heaven Ridge at the middle foot of Tashan.

After thousands of years of development, Dingtao Pass is also a rare Xiongguan city on the Songliao Plain, after the invasion of the demons, I didn't expect that the human race would go straight in, and I didn't have time to destroy the Dingtao Pass, so it fell into the hands of the Qinwang army led by Jiang Yin.

In the following years, Jiang Yin, Qin Hushan, Wu Zhidong, Yu Cang and others relied on Dingtao Pass, extended troops and horses along the two wings of the Juetian Ridge, and led the remnants of the remnants of the Northeast Pillar State General Xi Tongguang to rely on the Juexian Peak at the eastern foot of the Murowei Mountains, and with the support of the Northern Court, the Eastern Court and the county governments of the Southeast Region, it was difficult to build the Tashan defense line.

The establishment of the Tashan defense line gave the Taishang Tianzun Qin Shimin the opportunity to use the demon army led by the martyr king Qin Ran as the main force in Yongjing, gather reinforcements from various counties, and step by step expel and wipe out tens of millions of demon soldiers who had entered the Zhongzhou Great Plain.

For more than six years, countless miscellaneous demons have been cleared and expelled, but the main force of the demon soldiers who entered the Zhongzhou Great Plain was extremely cunning, divided into dozens of units and interspersed with detours on the Zhongzhou Great Plain with a radius of nearly 200,000 miles, and never fought a decisive battle with the main force of the demon army.

The supply of the demon race comes from the human race and hundreds of millions of creatures that inhabit and reproduce on the Great Plain of Zhongzhou, divided into several shares, and the speed of maneuver is extremely fast, in comparison, although the main force of the demon army is fighting on the inner line, but the later supply depends on the long-distance transportation of Yongjing and the general's mansion of the Zhuyu Pillar Kingdom, as well as the soldiers and horses of the same size of the demon army, and the field combat ability is weaker than that of the demon race, in the first two or three years, the results are really miserable.

In the thirty-fifth year of Jianxing, Qin Shimin, the Taishang Tianzun, took the Yongjing forbidden camp as the core, and transferred elite war horses from various departments to form the Xuanyuan Heavenly Army with 500,000 heavy armored war horses, and personally led Yongjing to join the Pingmo battlefield.

Although the demon clan also formed an extremely elite combat force in the Zhongzhou Great Plain to confront the Xuanyuan Heavenly Army, Qin Shimin led the Xuanyuan Heavenly Army to avoid the strong and weak, avoid the most elite combat power of the Demon Clan, and avoid the hasty decisive battle between the main forces, but stared at the relatively weak demon soldiers to chase and suppress, and ate one demon soldier after another in one bite, so that the balance of victory and defeat tilted towards the side of the human race step by step, and at the same time forced the demon soldiers who entered the Zhongzhou Great Plain to regroup in order to resist the rapid pursuit of the Xuanyuan Heavenly Army.

At this time, the main force of the demon soldiers who entered the Great Plain of Zhongzhou regrouped into two large groups: one main force of the demon soldiers entered the vicinity of Dongting Mountain south of Yongjing, and the three million demon army led by the Lie King Qin Ran was responsible for the defense, making it difficult for it to run in a long way;

At the end of the thirty-second year of Jianxing, the main force of demon soldiers entering the Zhongzhou Great Plain once reached 10 million, and then Jiang Yin and Xi Tongguang established the Tashan defense line to restrict the large number of demons from continuing to go south, but a large number of southbound miscellaneous demons used a large number of living beings as blood food, and constantly improved to the level of demon pawns, and constantly replenished the soldiers for the demon soldiers who entered the Zhongzhou Great Plain.

This made the Xuanyuan Heavenly Army, the Demon Expedition Army and the Zhulu Qinwang Army frequently have achieved results, and the cumulative number of demon soldiers exterminated was nearly 10 million, but it was not until the middle of the 38th year of Jianxing that the scale of the demon soldiers in Zhongzhou was reduced to 9 million.

However, the size of the demon army in Zhongzhou is beginning to decrease, which is an encouraging sign.

***********************

Dingtao Pass, the original town guard general's mansion became Jiang Yin's main general tent at this time.

Jiang Yin stood in the middle of the council hall, carefully scrutinizing the rotating map in the sky.

A few years have passed, and the years of hard fighting have not worn out his spirit, on the contrary, several years of difficult and tragic battles have sharpened Jiang Yin like a heaven-cutting spirit sword, and his edge is exposed.

Jiang Yin had already stepped into the fourth realm of the heavenly rank at this time, and even after stepping into the fourth realm of the heavenly position, he did not encounter a bottleneck period, and his cultivation was still increasing rapidly, and if he persisted like this for a few more years, he would be able to cultivate to the consummation of the fourth realm, and perhaps it was not without a chance to break through again.

At this moment, Jiang Yin's mood was a rare relaxation in several years.

The Supreme Heavenly Venerable Qin Shimin had already led a large army to five thousand miles in front of the middle foot of Dayan Mountain, and it would not take a month or two to launch an offensive against the more than four million demon soldiers who had retreated to Dayan Mountain.

At that time, even if it is only to drive away this Rakshasa demon soldier and recover Dayan Mountain, the offensive and defensive momentum of the human and demon races will be of great significance.

At that time, the Tashan defense line will be able to have a stable rear, and the soldiers, horses, and materials supported from the Eastern Court and the Northern Tingzhu General's Mansion will not be attacked on the one hand, and on the other hand, they will be reinforced at a faster and more effective speed, which will make the Tashan defense line more impregnable.

After that, it will only be a matter of time before the demon soldiers are exterminated and the demon calamity is quelled.

More than seven years have passed since the outbreak of the Demon Tribulation.

Although the pressure on various places is still like a mountain, but the dawn of victory has been initially seen, Jiang Yin is more relaxed than before, but there is no joy on his face.

In the past seven years, on the entire defense line of Chongguo, forty or fifty million generals have been killed.

Correspondingly, billions of civilians have fallen into the blood of the Rakshasa demons, and countless civilians have died of illness, starvation, and fear on the way to escape.

There are nearly three billion Terrans under the jurisdiction of the generals of the Northeast Regions, and after the defense line of Gulan Mountain was defeated, although a large number of Terrans fled to the Jedi on both flanks, Jiang Yin estimated that there might be only two or three out of ten who survived at this time.

The Zhongzhou Great Plain, as the area under the direct control of Xuanyuan Shangdian and Yongjing, as the richest land in Chongguo, once reached a peak population of more than five billion, but after the Rakshasa Demon Clan crossed the Great Yan Mountain, the Zhongzhou Great Plain suffered a devastating blow.

The demon soldiers gathered and scattered, gathered and scattered like the wind, and ravaged the entire Zhongzhou Great Plain in a few years, except for a very few fortified cities such as Yongjing that did not fall, the entire Zhongzhou Great Plain could hardly see the survival of the human race at this time.

In addition to the few large cities that survived, and in addition to the refugees who fled into the territory of the other Zhuguo generals' mansions nearby, Jiang Yin estimated that the population of the Great Plains of Zhongzhou had lost more than three billion.

What a tragic catastrophe this is, and it has been far more than 4,000 years ago.

In front of Jiang Yin's eyes, the bloody pictures that had happened kept appearing and jumping in his sea of consciousness, he let out a long sigh, and he didn't know what Taishang Tianzun thought in the face of such a tragic mountain and river, and whether he still remembered the ancient treasures of Liuyang Palace?

Just as Jiang Yin was about to continue to deduce the subsequent development of the situation, a golden sword edict broke through the air with a soft sound and fell into Jiang Yin's hands.

After Jiang Yin interpreted it with his divine sense, his face showed a look of surprise slightly.

He thought about it for a while, and then summoned Qin Hushan, Wu Zhidong and others.

In the past five or six years, Jiang Yin has guarded the defense line of thousands of miles of Tianling and Liangfeng, although the remnants of the Northern Court, the Northeast Domain, and the soldiers and horses supported by the generals of the Eastern Court and the Southeast Domain, there are tens of millions of generals who died on the battlefield of the Demon Resistance, but their sacrifice also made tens of millions of demon soldiers pile up in front of the defense line of Tashan Mountain.

At this time, the six million elite soldiers and horses of the Tashan defense line all accepted Jiang Yin's control and dispatch, except for Qin Hushan, Wu Zhidong, Yu Cang and others, more than a dozen Heavenly True Monarchs who were reinforced from the Eastern Court, the Southeast Region, and the Southern Court, and even the three Heavenly True Monarchs who were reinforced from the Yue Kingdom and the Tiannan Kingdom also obeyed Jiang Yin's orders.

Among the many Heavenly True Monarchs, although Jiang Yin's cultivation and qualifications are not the highest, he was the first to lead his troops to insert into the Peerless Ridge, and successfully held the Tashan Defense Line, and built a large number of heavenly weapons in the Tower Mountain to make up for the lack of combat power of the Terran generals, so that the more than seven million demon soldiers who were piled up in front of the Tashan Defense Line at this time did not dare to cross the Tashan Defense Line, which also made his power in the Absolute Heaven Ridge unmatched for a while.

After entering the main hall, Qin Hushan, Wu Zhidong and the others all saluted Jiang Yin respectfully: "Zhenjun summoned, is there something important?"

Jiang Yin put his hands behind his back and said lightly: "Just now I received an edict from the Taishang Tianzun, the attack on Dayan Mountain is imminent, the Taishang Tianzun summoned me to ask for advice, I may have to leave for a few days temporarily, at this time, the defense will be temporarily dispatched by Brother Hushan in the center......"

Jiang Yin didn't make much preparations, he didn't even take the horse, he went on the road alone, and flew to the city where Taishang Tianzun was at this time - Jiang Yin's cultivation at the peak of the fourth realm of the heavenly position, and he comprehended the sword intent of heaven and earth, mountains and rivers, and the heaven and earth qi in a radius of two or three thousand miles were all under his control, and at this time, among the demons, there may not be ten demons who can stay in him.

From Dingtao Pass to Lu Lincheng, with Jiang Pei and Lu Shaoshang, not to mention running slowly, it is easy to be discovered by the demon powerhouse, it is really better for him to be alone, go and return quickly......
