On the side of the Northwest Army, after Chu Yujia's order was issued, the entire army of the Chasing Wind Battalion withdrew from Hebei County with the Modao heavy armored cavalry and returned to Pingfu County.

On the way, Zhuang Jiade came to Chu Yujia's side and asked puzzledly: "General, the last general really can't understand, we can obviously annihilate the Southern Qi army, why do you want to let go of the Southern Qi army?"

"Why not?"

Chu Yujia asked without looking back: "Dong Haoyu is trapped in the valley, why don't you break through, don't you know?"

Zhuang Jiade shook his head and said, "The last general doesn't know, please make it clear to the general." ”

Chu Yujia sighed and said: "Actually, I didn't know it at the beginning, but then I saw Tao Beisheng and I knew it, it was this Dong Haoyu who was looking for this guy to assassinate me on the grassland, and he already knew that Tao Beisheng would definitely come to save him, so he would rather shrink into the valley to preserve his strength than lead the troops to break through." ”

Hearing this, Zhuang Jiade was puzzled and said: "But general, we have nearly 20,000 soldiers, no matter how powerful this Tao Beisheng is, we can still strangle him in the valley, why let them go?"

"Do you think it's worth exchanging the lives of so many soldiers for Tao Beisheng's life?"

Chu Yujia raised his head and said, "I appreciate Tao Beisheng and Dong Haoyu, but I feel that instead of exchanging so many lives for their lives, it is better to let them go and let them return to the Qi Kingdom." ”

"Before, our Northwest Army only deterred the Northwest, and although the other vassal states had heard of the Northwest Army's unparalleled iron cavalry, they didn't know how much trembling the Northwest Army's war horses could cause after trampling on the earth. ”

Chu Yujia narrowed his eyes and said: "What we did in Qianshu has already made the world hear the sound of the iron hooves of the Northwest Army's war horses, and also told the people of the world that it is okay to bully Ye Guo if you want to, but we must first see if our Northwest Army agrees, and see if all our Ye people agree." ”

"But this is just to tell the people of the world, because our army has a tradition, that is, not to keep prisoners, which is actually a very bad habit. ”

Chu Yujia glanced at Zhuang Jiade and said: "Because no one can spread the horror of our Northwest Army, let alone the fear of fighting against our army, only let this fear be spread, in the next battle, they will lose three points of courage before they can fight, then our Northwest Army will still have no reason to win?"

After listening to Chu Yujia's explanation, Zhuang Jiade finally understood.

Zhuang Jiade is a veteran who has followed the Chu family for two generations, and when he heard Chu Yujia's introduction, he couldn't help but sigh that this young general has really grown up, and it is more far-reaching than what the old general is plotting.

The biggest difference between Chu Qianwen and Chu Yujia is that Chu Qianwen pays attention to being above board, and it is my ability to defeat you on the frontal battlefield.

And Chu Yujia is for victory, he can do whatever it takes, and even before the war starts, he is already planning how to deal with the next war.

This is also why this time the Northwest Army did not move, and the world was shocked.

In three months, less than 70,000 Northwest Army stirred up a huge former Shu country.

Even after the Qi State entered the war, it still gained little.

After the wind chasing battalion withdrew from Hebei County, it returned to the town of Longzhen, Pingfu County, and the Liantian camp, which had held back its strength for three days in Hebei County, officially returned to the rear to rest.

Three days later, the Wind Chasing Battalion and the Liantian Battalion were dispatched, carrying a large number of siege equipment and resources sent from the rear to Eagle County, and the troops surrounded Tongzhou Pass.

Tongzhou Pass is the main road of traffic between the former Shu and the Later Song Dynasty, and only through the Tongzhou Pass can you enter the territory of the Later Song Dynasty, which is a very important place for the former Shu.

Of course, it is also a very important place for Ye Guo.

After taking Tongzhou Pass, Ye State's sphere of influence will be inserted into it like a long sword, completely cutting off the connection between Former Shu and Later Song.

If they take the entire territory of Eagle County in the future, it will be equivalent to cutting off the territorial intersection between the Later Song Dynasty and the former Shu, and even if they form an alliance in the future, they will have no chance.

But before that, the most important thing is to use Tongzhou Pass to kill chickens and monkeys.

This is to let the Later Song know the strength of the Northwest Army, and also let the Later Song know the strength of the Ye State.

Because between allies, sometimes it is not only a courtesy exchange or a communication of interests, but also a deterrence of force.

Only by letting the other party know what the fate of being an enemy is or what is the ability to be an ally can the relationship between allies become stronger.

Therefore, this is a battle in which the Northwest Army shows its military strength.

Chu Yujia gave Zhuang Jiade, Yang Renqi, Yan Tianrui, and Chu Haojie death orders.

Within three days, the Tongzhou Pass must be taken, and the entire territory of Eagle County must be taken within half a month.

This is a battle that does not cost as casualties and does not count any losses.

The four of them naturally knew why this was the case, so after arriving at Tongzhou Pass, the Chasing Wind Battalion, the Qianli Battalion, the Feixue Battalion, the Liantian Battalion, a total of 50,000 soldiers, and a large number of siege equipment, launched a fierce attack on Tongzhou Pass on the same day.

Others know the importance of Tongzhou Pass, but how can Qianshu not know it.

They had already deployed 50,000 elite soldiers in Tongzhou Pass to defend the city, but the defender still had the same idea as the defenders of Longzhen Mansion.

After all, the saying that it takes three times as many people to attack a city has been ingrained in the minds of many generals.

It's just that they didn't expect that when that person first said this, they never thought that there would be an army full of cavalry in this world.

Nor did they think that every soldier in this cavalry would be able to shoot arrows from their horses.

Nor did they think that an army could throw a stone several circles larger than a basin into the sky and throw it hundreds of paces away.

Before they came, Chu Yujia had already formulated tactics for them, and after they came, they just had to execute them.

This tactic is also very simple, attack, attack, attack, attack again, not as good as the attack at the cost of casualties.

There were no foot soldiers, so they let the horsemen be foot soldiers, and after rushing to a hundred paces from the city, they shot arrows, and then retreated like rotating gears.

A rain of arrows obscured the sky, and boulders fell from the sky.

Tongzhou Pass, which is known to be heavily guarded by 100,000 people, will not be able to break through even if it is 100,000 people, and it looks stormy under such a strong offensive.

And this time, the Northwest Army also used a city-breaking crossbow that had never been used before.

The shape of the city-breaking crossbow is nothing more than a wooden bow wrapped in a huge iron sheet placed horizontally, but the arrows fired are not ordinary arrows, but sharpened stumps.

At the time of starting, it was necessary to use three horses to draw the wooden bow to the fullest, and then load the stakes.

At the commander's order, the soldier immediately cut the rope that was attached to the horse.

Airplanes!

I saw rows of huge tree stumps shoot out, hitting the city wall and immediately smoke and dust.

When the smoke cleared, I saw that the arrows on the city wall had been shot through and collapsed by the huge wooden stakes.

Even if it is not pierced and collapsed, only a crack appears, but it is hit by a stone bullet falling from the sky, and most of them will collapse immediately.

I saw this scene like I had never seen before.

The former Shu soldiers were dumbfounded.

I can't help but wonder, am I fighting against ordinary human beings?

Are you sure it's not the gods who came down to earth?
