In the north of the Tianlun Mountains, at the border between the Blue Star Country and Yan and Vietnam, there is a section of more than 100 miles of junction, the terrain here is full of hills and sand dunes, there is a strange white fog all the year round, there is no sunlight all year round, the natural environment is extremely responsible for the harsh, even the birds are difficult to fly through here, and there are all kinds of strange monsters living here, they like to feed on ordinary creatures such as people, and they are even more vicious. Therefore, this place is also known as the Flying Ridge.

During the war between Guizhou and Vietnam, because of the special natural environment, it did not become a battlefield for the two countries to fight, there was once a Vietnamese army corps wanted to cross this place to kill Gui, but it was delayed for a long time by the harsh environment and countless demon beasts at the Juefei Ridge, and finally delayed the fighter, and the Vietnamese army had to give up the way to enter Gui from this place. Therefore, even after the establishment of the Blue Star Country, there was no army stationed here, but on a narrow hillside called Qiongling more than ten miles away from here, a garrison army of 1,000 people was stationed, and the usual task of this army was to exterminate the demon beasts that escaped from the Flying Mountains.

Since the Qin army began to invade the eastern countries, in order to prevent any possible invasion by the Qin army, the number of garrison corps here began to increase greatly, reaching more than 20,000 people at its peak. Not long ago, the Seventh Army led by Sun Bin was stationed here to guard the hundreds of kilometers of border, including the Juefei Ridge, to prevent the Qin army from raiding.

The duties of the Seventh Army are extremely important, because as long as the enemy crosses Qiongling, behind them is the western prairie of the Blue Star Country, and there is almost no danger to defend all the way, and the western prairie is the area where the population and production of the Blue Star Country are concentrated, so the military significance of Qiongling to the Blue Star Country is even no less than Tianlun Peak.

Just when Wu Huan, the commander of the Qin army more than 1,000 miles away, led an army of 300,000 to attack Tianlun Peak, a Qin army of more than 100,000 people quietly set off from the territory of Yue and passed through the Juefei Ridge.

This Qin army is composed of 30,000 cavalry, 10,000 flying soldiers, and 60,000 heavy armored infantry.

In order to pass through this strange area and not attract the attention of the Blue Star Army, all the soldiers traveled on the spirit beast car, and even the Demon Crow Flying Horse of the Flying Horse Force fell to the ground and was checked by a special spirit beast car. In addition, the unit is equipped with more than 500 giant golems, which are armed with huge magic weapons such as heavy axes, and are responsible for clearing the way in front of the team.

With the assistance of the puppet warriors, the Qin army troops built bridges in rivers, opened roads in mountains, and killed demons, and quickly passed through this wasteland at a speed of dozens of kilometers per hour, and finally came to the border area of the western prairie of the Blue Star Country.

However, even though the Qin army was cautious on the march and barely encountered any obstacles that could cause trouble at the Flying Ridge, its whereabouts were discovered by the reconnaissance team of the Blue Star Army's defenders shortly after they entered the Flying Ridge. The appearance of the Qin army in this place, and the number of them was so large, that it immediately caused Sun Bin's shock, and after reporting to Hanzhong City at the same time, Sun Bin immediately sent the Seventh Army to attack. As soon as the Qin army appeared in the grassland area, it was immediately attacked fiercely by the nearest border guard unit of the Blue Star Army.

However, the Qin army suddenly burst out with strong combat effectiveness at this time, and in the face of the border guards of the Blue Star Army who came to block it, the main general of the Qin army took the lead, leading the army to launch a fierce attack without fear, defeating the defenders of the Blue Star Army in one go, and in turn launched an attack on the Qiongling position where the main force of the Seventh Army was stationed.

Sun Bin was shocked, and immediately organized a large army to launch a counterattack, relying on Qiong Ling's solid position and geographical location, and launched a fierce offensive and defensive battle with the Qin army.

On a wide and flat small slope, tens of thousands of Qin army troops formed a huge battle formation and launched a fierce attack on the forward position of the Blue Star Army on the slope. Spells and various pillars of attack light shot out from the military formation, and fell densely on the Blue Star Army's defenders' positions, provoking waves of explosions.

A small battle formation composed of all heavy infantry under the cover of hundreds of giant puppets, braving the strong counterattack artillery fire of the Blue Star Army, killing dozens of small pillbox positions at the top of the slope, and engaged in a desperate struggle with the defenders of the Blue Star Army.

The goal of the Qin army is a Qiongling mountain behind this slope that is only a few hundred meters above sea level, as long as this highest point is captured and the defenders here are eliminated, the Qin army can really open the passage to the hinterland of the Blue Star Country.

But how could Sun Bin let the Qin army get his way, and the Seventh Army launched a counterattack with all its might, and the artillery deployed in the hidden positions in various mountains and ridges concentrated on the Qin army's battle array to launch a fierce bombardment. Under the continuous bombardment of more than 100 120-mm heavy guns, tens of thousands of Qin army's military formations were quickly broken through the protective shield, and a large number of Qin artillery pieces were killed and wounded.

But at this time, the Qin army had already rushed to the forward position of the Blue Star Army, and for fear of accidentally injuring his own defenders, Sun Bin was forced to order to stop the bombardment. The cunning Qin army also understood the power and weakness of the Blue Star Army's artillery, and took the initiative to withdraw the 10,000-strong battle formation and form hundreds of small battle formations to attack, so that it would be difficult for the Blue Star Army's artillery to give full play to the advantage of attacking dense targets.

In the air, the battle for air supremacy over the battlefield was also raging, but this time, the scale of the battle was gradually tilting towards the direction of the Qin army. The Blue Star Army Air Force deployed here only has more than 200 fighters, and in the face of thousands of Demon Crow troops with absolute superiority, no matter how advanced the Blue Star Army's fighters are and how brave the pilots are, they are no match for the Qin Army's Demon Crow Forces. The Seventh Army quickly suffered heavy losses under the frenzied attack of the Qin army, and in just an hour after the start of the battle, almost all the fighters were shot down!

Having lost air supremacy, the Seventh Army was soon defeated by the frenzied attacks of the Qin army. The Qin army's army of demon crows swooped down on Qiong Ling's position in black pressure, dropping spells one after another, highlighting clusters of flames, covering the attack of the Qin army's ground troops under the mountains. Two hours after the start of the battle, almost all the small pillboxes and positions in front of Qiongling, the main peak of the Blue Star Army, were destroyed by the Qin State, and only three or four peaks, including the main peak of Qiongling, were still under the control of the Seventh Army Corps. The Seventh Army suffered even more heavy casualties, and almost half of the troops lost their combat effectiveness.

Finally, after holding out hard for six hours, the Blue Star Army finally couldn't hold on, and the Qin army finally captured the entire Qiongshan after paying a huge price of nearly 30,000 casualties. After Sun Bin knew that it was impossible to recapture the position, he had to lead the remaining troops to withdraw from the position and hide in a small county town called Danyucheng dozens of miles away to avoid the danger of being completely annihilated by the Qin army.

From the time the Qin army began to attack Qiong Ling, the top brass of the Blue Star Kingdom immediately knew about the situation. Lin Da immediately ordered the three group armies closest to Qiongling, led by Shen Hao and others, to urgently support the Seventh Army Corps. However, when Shen Hao arrived with his army, Qiongling had already changed hands. This shocked Lin Da, and he hurriedly ordered the three army groups to continue to unite with the Seventh Army Corps and immediately attack Qiongling.

Unexpectedly, as soon as the Qin army occupied Qiongling, they immediately made defensive arrangements and laid out an incomparably mysterious super array on the mountain range, which greatly enhanced the defensive power. No matter how the Blue Star Army's artillery bombarded, the protective shield of the Qin Army stood still, and it was unable to break through this formation for a while. What surprised the Blue Star Army even more was that the reinforcements of the Qin army also arrived at this time, and an army of more than 100,000 people once again passed through the Juefei Ridge, gathered with the Qin army on the Qiongling Ridge, and in turn launched an attack on the four group armies of the Blue Star Army.

Sun Bin and Shen Hao and others were surprised, and hurriedly led the army to counterattack, and the two sides broke out in the grassland near Qiongling, where the largest battle between the Qin army and the Blue Star Kingdom broke out. The total strength of the two sides involved in the battle exceeded 500,000, including 180,000 in the Qin army and 300,000 in the Blue Star army. This battle was fought in the dark, and the two armies used their own methods, all kinds of magic spells and various advanced weapons appeared, turning this flat prairie into a Shura hell.

The battle lasted for several days before it gradually subsided, and the Blue Star Army annihilated forty or fifty thousand Qin troops, and lost more than 100,000 people themselves. Because of the heavy casualties, the two sides were forced to withdraw, and the Qin army continued to stubbornly occupy Qiongling, while the Blue Star Army had to retreat to Danyu County because of the unfavorable attack, and was ready for a comprehensive defense.

The Qin army entered the prairie, and the entire western region of the Blue Star Country suddenly became a dangerous area, and various cities in the western region immediately activated emergency measures, and urban residents began to continuously evacuate to the eastern region to prevent further invasion by the Qin army.

At this time, the Qin army also suddenly increased its troops, and suddenly sent more than 100,000 people from China to support the front army, making Qiong Ling's Qin army as many as 300,000. Just as the top leaders of the Blue Star Country were preparing to deal with the invasion of the Qin army, unfavorable battle reports came from the battlefield in the northwest direction again.

On September 16, 29 years of the Blue Star Army, in the northern battlefield, the Qin State suddenly launched a large army and raided the last remaining three counties of the Yan State, and the 200,000 army entered the last important town of the Yan State, Zanxi City, almost completely wiped out the last strength of the Yan-Zhao coalition army, and even the expeditionary corps of the Blue Star Army who assisted in defending this place could not resist the attack of the Qin army, and was forced to abandon the land of the three counties with the remnants of the Yan-Zhao coalition army and retreated to the territory of the Blue Star State.

However, the raiding Qin army did not spend any energy to occupy and consolidate the land of these three counties, but frantically pursued the Kuifeng army and the remnants of Yan Zhao's army. In front of the enemy with absolute numerical superiority, Kui Feng had to choose to avoid the battle and fully command the army to retreat. Fortunately, with the strong transportation capacity of the Zanxi Railway, the army was able to withdraw most of its regiments and equipment to the country safely in the shortest possible time, avoiding the unfavorable situation of being surrounded by the Qin army.

In order to cover the retreat of the large army, Kui Feng had to lead an elite army of 10,000 people and fought a big battle with the Qin army. In this battle, Kuifeng's troops suffered a great defeat, and he himself almost died in the chaos, and finally was seriously wounded, barely fighting a bloody way to escape from the encirclement. The rest of the army retreated all the way to the border of the Blue Star Country, but fortunately, the Flying Leopard Legion led by Schroeder arrived in time to block the pursuit of the Qin army, and only then did they escape.

Enraged, Schroeder led the Flying Leopard Legion to unite with the large army that had withdrawn to the country, and fought the Qin army at the border for several days. Although a large number of Qin troops were killed, they also lost several important positions in a row and were forced to retreat to Tanku City, which was dozens of miles away from the border, while the Qin army occupied the border area more than 100 kilometers north of the Blue Star Army in one go.

At the same time as the invasion of the Blue Star Kingdom itself, the Qin army also achieved a major victory in the direction of the Chu State. In November of the 29th year of the Blue Star Army, the prince of Qin led a large army to march to the south of Chu again, and annihilated the last 300,000 Chu allied troops in Nanchong City, an important town in the south of Chu State, and completely occupied the entire Chu State. The remnants of the Chu resistance were forced to flee by ship from the southern seaport in the direction of the Blue Star State. Because of the hasty retreat, the Chu army did not have time to destroy the naval ships of the ten subject countries along its southern coast, and the more than 100,000 navies of these countries were forced to surrender, and thousands of ships were all occupied by the Qin army, which made the Qin army, which had never had a navy, suddenly have a sea force that is not weak, and can even directly threaten the mainland of the Blue Star Country from the sea.

However, in just a few months, the Qin army attacked from three sides in the western part of the Blue Star Kingdom, the border of the Yan Kingdom, and the southern region of the Chu State. In addition to Tianlun Peak, the Qin army has made breakthroughs in all directions, forming a powerful situation of a full-scale invasion of the entire Blue Star Country!
