This time, the purpose of the Western Chu Army was to occupy the slopes on both sides of the Fengchuan Valley and open up a passage to support Qianshu.

However, for the relatively flat southern slope, it was impossible to attack for a long time, and the troops were lost, and the main general of the Western Chu army began to lose his breath.

After the third all-out attack was repulsed, the Western Chu army launched a fourth round of attacks.

In this battle, the two sides fought from noon to dark, and it was not until the soldiers on both sides were exhausted that it came to an end.

After a whole day of fighting, the casualties of the Northwest Army were only less than 200, but the Western Chu Army paid the price of nearly 3,000 people, but after paying more than ten times the battle losses, the southern slope of the Fengchuan Valley was still under the control of the Northwest Army.

At this time, the chief general of the Western Chu army finally realized that the soldiers who occupied the top of the slope were definitely not ordinary Ye army soldiers......

And in Ye State, I am afraid that there is only one Northwest Army that can have such combat power.

And these people are definitely the elite of the Northwest Army, otherwise how could he lose so badly?

Of course, there is also an excuse for yourself.

But no matter what, the main general of the Western Chu Army also realized that although the opponent's troops were not many, they had a geographical advantage, and with their current situation, they were afraid that it would be difficult to tear apart the defense line of the Northwest Army in a short time.

However, the situation in Qianshu is urgent, and they already know that now the Northwest Army and the Yu Yun Army have begun to give up continuing to advance in the outer counties of Qianshu to attack the capital of Qianshu.

Although he had never seen what it was like when the Northwest Army and Yu Yunjun jointly attacked the city, just by hearing the past achievements of these two armies, they could conclude that even if there were nearly 200,000 people stationed in the former Shu Capital City, it would be difficult for them to hold out to the end.

After all, everyone knows that there has been no threat from foreign enemies in Qianshu over the years, and most of the troops supported are decorations.

Let them fight, it is no different from sending them to death.

Otherwise, it would not have been defeated so easily by the Northwest Army in a head-on decisive battle.

According to Xi Chu's estimates, the former Shu capital can last for a month at most......

But now, this Fengchuan Valley can't be passed, if it can't take the Fengchuan Valley, the Western Chu army will have to make a detour to the territory of the Son of Heaven into Qianshu.

That would result in a month's delay on the road.

It doesn't matter if they go or not......

Under such circumstances, the commander of the Western Chu army could only send people to ask for help from the main army.

In the evening, the officers and men of the Western Chu Army were resting, while the officers and men of the Northwest Army were rebuilding the stone wall and preparing large and small stones.

Even Chu Yujia can't be idle, there are so many boulders on the top of the slope, and if they run out of one and one less, if they want to resist the continuous attack of the Western Chu army, they need more boulders to assist.

After all, they have few people, and everyone cannot be idle, and they must continue to mine.

Chu Yujia has been fighting fiercely with the soldiers for a day, and he also followed the soldiers to catch up with the stones at night, and the soldiers have seen his dedication, no matter how hard and tired people are, no one complains.

Even his own generals are so desperate, so what is this hard work of his own?

By the time Chu Yujia helped the soldiers finish mining the stone and arrange it, the people were already so tired that they were about to collapse.

Chu Yujia sat on the ground and gasped for air.

The whole body is trembling incessantly, he is also a human being, not a god, and he will be tired.

Qi Zhong stepped forward, handed the water bladder to Chu Yujia, and said softly, "General, drink saliva!"

Chu Yujia smiled, he didn't bother to say thank you again, took the water bladder and slowly took a small sip, and then took a big sip.

Zuo Jinkai walked over with a bowl of hot soup and handed it to Chu Yujia.

Chu Yujia took the soup bowl and drank it all after blowing it.

This soup is actually not an ordinary soup either, it is something developed by Meng Feihang's ordnance battalion.

Originally, Chu Yujia didn't take it seriously, but now it seems that this is really a treasure.

This is a soup paste made from beef powder made from dried beef and then ground into flour.

You can't see anything in normal times, but it's a very convenient thing at times.

It's easy to carry and nutritious, not only filling your stomach but also warming your body.

It is a suitable ration for the Northwest Army, which has to travel all year round and does not know when it will be replenished.

After drinking the beef soup, Chu Yujia sat cross-legged facing the moon, carrying the internal breathing method to restore the depleted essence.

Seeing this, Qi Zhong and Zuo Jinkai were not good at bothering anymore, and the two of them sat aside, and also followed Chu Yujia's example, and began to meditate calmly to recover the lost essence.

In the middle of the night, the Western Chu army did not stop, and launched several feints.

Their purpose was to keep the Northwest Army at the top of the slope at peace and rest.

After all, there are many of them and there are few soldiers in the northwest, so this method is also the most effective method.

At dawn the next day, the Western Chu army launched another major attack.

This time, the Northwest Army was more prepared, the stone was rounded, and the speed and force of the roll towards the hillside were greater.

The offensives of the Western Chu army were round after round, but in the end they were all repelled again and again by the Northwest Army.

The battle lasted from morning to late at night.

At night, the Western Chu army continued to harass with feint tactics.

As long as the resistance of the Northwest Army weakened slightly, the feint attack of the Western Chu Army immediately turned into a real attack.

The two sides spent another day in this kind of battle in which it is difficult to distinguish between the real and the false.

The next day, the Western Chu army began another large-scale attack, launching a fierce attack on the top of the southern slope.

For three days in a row, fierce battles were fought day and night, and even the iron man couldn't bear it.

Now the Western Chu Army is competing with the Northwest Army for willpower to see who will not be the first to persevere.

But the Ye people have always been known for their tenacious fighting spirit, and the Northwest Army is the most tenacious of the Ye army.

What's more, there is still Chu Yujia in the army, and the Western Chu Army and the Northwest Army are competing for willpower, and they definitely chose the wrong person.

On the fourth day, the officers and men of the Western Chu Army could no longer hold on, and they could not launch a decent offensive again.

During the attack, most of the soldiers gathered at the bottom of the hillside, the thunder was heavy and the rain was small, at most they scolded their mothers, and they never rushed up again.

The chief general of the Western Chu Army knew in his heart that his soldiers had reached the limit.

If you force your own soldiers to charge at this time, it will have no effect, and it will only lead to greater casualties.

On the side of the Northwest Army, although the fighting spirit has not collapsed, it is facing a bigger and more thorny problem, that is, the imminent shortage of water and food.

Originally, Mt. Aomine was a rainy area, which everyone knew, but after they climbed to the top of the slope of the Kazegawa Valley, the sun was so big that it didn't rain for a few days.

Nowadays, the food is okay and can last for more than ten days, but the water source is depleted too quickly and cannot be replenished at all.

In the past few days, the reason why the soldiers were able to persist in fighting and not die of thirst was due to the better habits of the Northwest Army, no matter where they went, they would carry a large amount of water even if they did not bring food, but they could not withstand such losses.

At this point, Chu Yujia also began to worry.
