The 10,000 cavalry of Ahuanu, who had long been out of the battlefield, divided into three ways, quickly arrived at the battlefield where they were fighting, and took advantage of the physical strength and speed advantage of the horses that had rested for a long time to rush into the battlefield where they were fighting.

These cavalry did not love to fight, but only to separate the two warriors, and roared across the battlefield like a storm.

The Rong soldiers in hand-to-hand combat also took advantage of the rush of the rescue cavalry to quickly break away from the enemy and find the war horse, and retreated north without looking back.

As early as when the Ahuanu army was reinforcing to the south, Fang Yuanheng was overjoyed and immediately ordered the Xuanjia cavalry to leave the battlefield and kill at the banner of the Rong people's Chinese army.

But as soon as the Xuanjia cavalry left the battlefield, they saw that Xiao Jinxing and the others had already gone north without a trace.

On the battlefield a quarter of an hour later, in addition to the dead corpses, only the soldiers of the Qin army looked at the Rong cavalry fleeing north, helpless.

Since ancient times, infantry against cavalry, if they can't surround and annihilate it, then they can only let it escape.

Therefore, throughout the ages, if the Qin State won the battle against the Rong people, most of them would only be a defeat battle, and there were few annihilation battles.

Ten years ago, Fang Yuanheng took advantage of the terrain in Xiaoguan to annihilate tens of thousands of soldiers, and such a result is only seen in history. This is the reason why most of the Rong generals will hear the change of color.

Under a little observation, Fang Yuanheng saw that the Rong soldiers were retreating in a hurry, so he ordered the whole army to pursue the Rong people to the north.

gave an order, but saw tens of thousands of Qin troops killing north, and the momentum shook the sky.

In the year 589 of the Great Zhou calendar, in the autumn, on the night of September 27, the Qin army regained Haiwu County on the night after a one-day battle with the Rong people, which is known as the Battle of Hainan.

In this battle, more than 4,000 soldiers were beheaded, more than 130 soldiers were captured and wounded, and 7,200 casualties were inflicted.

Most importantly, the Qin soldiers captured more than 70,000 Rong men and horses.

That night, Fang Yuanheng reported the results of today's battle to Xijing and Yuanzhou at the same time. He also ordered the whole army not to rest, leaving 10,000 defenders to garrison Haiwu County, and the remaining 50,000 horses to march north early tomorrow morning to take Jinggang County.

Four days later, Fang Yuanheng led an army of 50,000 people, and without encountering a single soldier's resistance, he successfully occupied Jinggang, the second largest county in Qinlan County.

After arriving in this county, Fang Yuanheng did not stay, but after discussing the marching plan with Jiang and Zheng, he continued to go north non-stop.

To the north of Jinggang, there is a hill that runs north-south, although it is a small mountain, it is also compared with the Qinlan Mountains and the Sumeru Mountains. But it itself is a little bigger than Yushan.

The name of this mountain is called Yuanshan, this mountain runs through the north and south of Qinlan County, and Qinlan County is divided into Qinxi and Qindong, among them, the six counties of Qinxi are Zichuan County, Ningdao County, Luoshui County, Tianyu County, Artemisia County, Lanlu County, and the five counties of Qindong are Qinyu County, Chaopu County, Suibei City, Guping County, Yangping County from south to north.

According to the information sent by the "swallow", Fang Yuanheng led more than 50,000 troops to the north along the western Qinxi road, and in half a month, he successively recovered the five counties of Zichuan, Ningdao, Luoshui, Tianyu and Artemisia Lu.

After more than half a month of continuous marching, the sergeants under Fang Yuanheng were exhausted, but they were still able to grit their teeth and continue to maintain a high fighting spirit, which is what a strong army in the world should look like.

In the past half month, Fang Yuanheng also had the idea of going west directly to recover Lingzhou and the counties south of Lingzhou, but after thinking about it, he still gave up. Although this can launch a surprise attack on the Rong people who are confronting Wonju, and the odds of victory are very high, he will expose his back to the tens of thousands of Rong cavalry who have fled from Haiwu County.

Once he makes a detour into Lingzhou, and the tens of thousands of Rong soldiers attack from behind, it will be more than worth the loss, and the situation of attacking the Rong people in Yuanzhou will become a flank.

As a last resort, Fang Yuanheng still made a steady arrangement and continued north along Yuanshan.

After the army stopped at Haolu County, Fang Yuanheng ordered the whole army to stand by, suspend the march, and rest in place.

He knew that less than a hundred miles north was Lanlu County, the northern boundary of this county ended at the Qinlan Mountains, and to the east it could bypass the north of Yuanshan Mountain and border with Yangping in eastern Qin, and to the west was the official road leading to Lingzhou.

In the past half a month, although those Rong people have not blindly fled, they will occasionally suddenly launch sneak attacks on Fang Yuanheng's army from all over Yuanshan, but Fang Yuanheng is old in military affairs, and his precautions against this are impenetrable, and he has not let the Rong soldiers take any advantage.

But with the recovery of more and more lost land, Fang Yuanheng became distressed, except for the location of Haiwu County, which was too important, Fang Yuanheng left 10,000 troops to garrison, and Fang Yuanheng only left 2,000 soldiers to guard the rest of the counties, which caused the original 70,000 troops when they left Yushan in the north, and only the current more than 40,000 people remained.

Fang Yuanheng realized that the Rong people were likely to use the strategy of luring the enemy deep and dispersing their forces long before they went north.

Because of this strategy, Rong Jun also used it against Zhao Zhihai at the beginning.

However, Fang Yuanheng believed that with the excellent quality of his soldiers and the pervasive intelligence of the "swallows", the army would be able to completely wipe out the main force of the Rong people south of Artemisia.

However, in the battle of Hainan, a siege and annihilation battle carefully planned by him turned into a rout and escape battle, and on the grand battlefield with 100,000 fierce battles, a battle did not destroy many enemy soldiers.

After that, the counties in the north were abandoned by the Rong people one after another, and he knew at a glance that it was a plan by the Rong people to disperse the Qin army.

For this reason, he once deliberately marched from the foothills of Yuanshan Mountain to try to lure the Rong soldiers to sneak attack, and then annihilated the outcropping enemy's plan was also discovered by the vigilant Rong people, often after the two armies intersected, the Rong people touched and left, and did not entangle.

Therefore, the current situation also gave Fang Yuanheng a headache.

Seeing that the soldiers were tired at this time, he ordered the army to temporarily rest in Artemisia County for some time.

In addition, the excessively fast march in the past half a month has made the grain and grass sent from Yushan somewhat unavailable, which is also one of the purposes of postponing the march.

Moreover, Fang Yuanheng also found that in the seven counties recovered, although the people still had grain in their hands, the grain and grass stored in each county had been cleaned up by the Rong people, which caused the grain and grass needed by the army to be transported from Xiazhong County.

And Artemisia County is more than 800 miles away from Wenshui City, so the manpower and material resources required for a trip to transport grain and grass are already a big burden.

Often, when transporting a soldier's rations for one day to Artemisia County, Wenshui City was required to prepare three days' worth of food for one person, two of which were to be provided to the people transporting grain and grass for food on the road.

The amount of grain and grass consumed by 60,000 soldiers per day is even more staggering.

At this time, Fang Yuanheng was a little nostalgic for the good days when he led troops to fight outside and Zhao Zhihai sat in the center to provide food and grass for his army.

Faced with these lists of grain and grass losses, he sincerely admired Zhao Zhihai for the first time.

However, at present, his army is in the north of the Chen army, to the west is the pass where Qin Lan has lost, and to the southwest is the counties of Lingzhou, and to the east, he will go to the eastern Qindong region to continue to play the game of cat and mouse with the Rong cavalry.

Where to go, let Fang Yuanheng fall into deep thought.

The Rong people never fought with themselves, which made Fang Yuanheng extremely uncomfortable, for him, whether it was a group battle or a small-scale scuffle, or a sneak attack battle, no matter what, he could think of the best strategy to defeat the enemy, but obviously these Rong people opposite him did not have such plans, and even Fang Yuanheng thought that they had no intention of fighting at all, just running stupidly in front.

Moreover, these soldiers have already taken away the grain and grass from the counties, and they are not worried about the problem of grain and grass in the process of running stupidly, but this is precisely Fang Yuanheng's weakness.

Before he could sort out the strategy for continuing the operation, Fang Yuanheng still ordered Xia Zhong County to start recruiting troops, hoping to gather 30,000 horses to defend the counties he occupied a month later.

Once enough men and horses were gathered again to restore the appearance of the army when they left Yushan in the north, the army could bypass Yuanshan and attack Yangping County in eastern Qin.

At that time, let's see where those Rong people can escape.

Although his own troops were slightly insufficient, causing the army to be unable to take the initiative to attack, his "swallows" would report the route of the Rong people's escape to Fang Yuanheng every three days.

At the very least, where the Rong people are, Fang Yuanheng has always understood.

At the same time, Fang Yuanheng also wrote to Yuanzhou, hoping that Zhao Zhihai could organize an operation to launch a northward or westward expedition.

The northward march hopes to eliminate the Qingshui Rong people and join forces with Zhao Zhihai at the Qinlan Passes, while the Western Expedition hopes to recapture the Xiao Pass and lock the Rong people's retreat in the Qinlan Three Passes, so that whether it is catching turtles in the urn or closing the door and beating dogs, the strategic initiative will be in their own hands.

Just when Fang Yuanheng was in Artemisia County because of the dispersion of troops and the high pressure on grain and grass. Zhao Zhihai in Yuanzhou also planned and launched several actions at the same time, which had nothing to do with Fang Yuanheng's letter, because how could Zhao Zhihai, who was ranked in the middle of the list, not know the importance of cooperating with Fang Yuanheng in battle.

On October 21, October 21, 589 of the Great Zhou calendar, Wang Min's 30,000 troops received Zhao Zhihai's military order, and launched an attack on the high ground on the south side of Yinyangou Chidao with 10,000 reinforcements from 10,000 troops.

Wang Min is worthy of being the first wise general under Zhao Zhihai, these times, he has not only built a solid defense of the highlands on the north side of the Chidao, but also deployed a large number of troops in the depths of the north and south hills of the highlands on both sides of the Chidao occupied by the Rong people, in order to counterattack this day.

He sent spies to the outskirts of Xiaoguan from the hilly roads every day to observe the movements of the soldiers.

If it weren't for the fact that Wang Min had just arrived at Yinyangou when Zhao Zhihai retreated westward, if it was a little later, then Xiao Jinxing's plan to go north would definitely be detected by Wang Min in advance.

After confirming that the Rong people did not know that the Qin soldiers were about to attack, Wang Min's army attacked the eleven heights occupied by the Rong people from the north and south of the Chidao Heights at the same time.

But Wang Min also divided the focus, he sent 10,000 people in advance to block the east of the highland on the west side of the Yinyangou Chi Road, which was originally guarded by Xue Simu, in order to prevent the highland defenders at the east exit and the Xiaoguan defenders from coming to the east.

He also sent 5,000 men to block the troops on the south high ground of the exit on the east side of the Chi Road, blocking their road from the Chi Road to the west.

Another 20,000 men were sent to attack the remaining eight highlands outside the garrison heights of the East and West Koukou people at the same time.

On both sides of this bloody millstone-like gallop road, which was only six miles long, the two armies fought fiercely again after less than three months.
