The golden mean, this is the first time in this world, and Hu Xiao, a military general who is halfway through the study, naturally can't understand it.

Yang Mu didn't bother to explain, because this kind of game between countries couldn't be explained clearly for a while, and it was impossible for him to talk to Hu Xiao about the examples of so many allies in history who made small moves behind their backs and finally parted ways.

As a military general, many things are slowly comprehended and experienced when actually dealing with problems, and when you have enough experience, you will naturally be able to understand the truth.

This is also why, the personal guards around the emperors of various countries generally have a good development later.

For example, Wei Zhongquan, Zhu Xi, Han Tong and others, these three generals of Cangguo, are all from the personal guards of the first emperor.

The reason is very simple, on the one hand, the guards are trustworthy, and the monarchs and ministers have a sense of security with each other, which can be regarded as a two-way dependence relationship.

On the other hand, and the most important point, the guards have been by the emperor's side for a long time, and they can learn a lot of things, and they also have a tacit understanding with the emperor when they do things, and they are more handy in their use, and they are more capable than those soldiers who were born in a hurry.

The golden mean that Yang Mu said is the way in which countries deal with problems, as long as they are within a certain degree and do not harm the fundamental interests of both sides, in fact, there is still a lot of room for maneuver in the middle.

For example, cooperating with the Dong Kingdom, although the goal is to swallow the Sheng Kingdom, in Yang Mu's opinion, it is basically impossible.

It is far more difficult to attack the city than on the frontal battlefield, and in the case of a small difference in strength, it can be said that it is very difficult to take Sheng Guo in one go, and Sheng Guo can recruit a large number of new soldiers at any time to serve as defenders of the city.

When the time comes, when the heat in the minds of the monarchs and ministers of the Dong Kingdom has passed, and they find that their losses are so big and they do not have the ability to annex the Sheng Kingdom, they will begin to weigh the pros and cons and stop losses in time.

……

A few days later, Yang Mu met the emperor of the cave country again who had a big belly and was panting when he walked.

This time, the two got along much more harmoniously.

In order to realize his ambition of territorial expansion, the Emperor of Dong gave high hopes to Cangguo.

As soon as people get old, they will inevitably be a little dim, and the emperor of Dongguo is one of the representatives, so he wants to leave a brilliant mark in the history books in his lifetime.

Yang Mu verbally satisfied him and sketched a beautiful blueprint for him.

As for the implementation...... Oh, let's work hard!

After the two emperors reached a cooperation, they signed an alliance together.

The two sides agreed that the two countries would join forces to attack Shengguo, and as long as Shengguo was not destroyed, the covenant would not be dissolved for a day, and in terms of civil trade, each other would be exempted from commercial taxes, and the books, paper, and clothing of Cangguo would be supplied to Dongguo on a priority basis, and all the money in the transaction would be offset by iron products and horses.

On July 16, Dong Guo officially declared war on Sheng Guo.

At the same time, 500,000 troops on the border of the Dong Kingdom poured out their nests and launched large-scale attacks on several cities on the border of the Shengguo with lightning speed, and captured several passes one after another.

Sheng Guojun finally realized the seriousness of the problem.

The destruction of the 300,000-strong army caused a series of consequences, and after more than 20 years, a major war finally broke out between the Dong Kingdom and the Sheng Kingdom.

But this time is different from the last time.

Twenty years ago, it was Sheng Guo who invaded Dong Guo with his troops, captured more than 30 cities in Dong Guo, and invaded almost a land the size of Cangguo.

This time, it was the Dong Kingdom, which had been in a passive position in recent years, that took the initiative to launch a war against the Sheng Kingdom.

Therefore, when Dong Guo's declaration of war was presented to the Shengguo court, the whole country was shocked.

The soldiers and soldiers of Cang who heard the news were overjoyed.

After having the allies, you can attack and retreat, and you can defend it, and you have no worries.

That night, the Blue Dragon Legion launched a night attack on the 200,000 Sheng troops who came to support.

It's a pity that the Sheng ** team learned the lesson of the previous time, the guard at night was very tight, a large number of scouts were scattered, and the Blue Dragon Legion was discovered not long after it approached, and the results achieved were very small.

This continued until the third day.

Sheng Guo couldn't afford it anymore, and the general Deng Zhi led his army to storm the two cities where the Blue Dragon Legion was stationed.

"Why has this country become so powerful in a short period of time? If we let it go......"

Deng Zhi stood on the high chariot, looking at the attack and defense of the two armies in the distance, and felt very uncomfortable.

He remembered that a year ago, most of the current land of Cangguo was still a small country called Zheng Guo, and the national strength was very weak, if it were not for the Zheng Guo royal family was a branch of the Sheng Guo royal family, and a large amount of money was donated to the major nobles every year, it would have been swallowed up long ago.

Now, the place that was praised as a money bag by the nobles of Shengguo, the soldiers who came out were so powerful.

After a morning of fierce fighting, the Sheng army did not break through the city occupied by the Blue Dragon Legion.

A large part of this is due to the existence of repeaters.

A series of crossbows were erected on the city wall, forming wave after wave of oppressive covering, and although the Sheng army climbed the city wall several times, they were quickly extinguished.

For one day after another, the soldiers of the Sheng army were exhausted.

"That's it for today, order the withdrawal of troops, and find a way tomorrow." Deng Zhi breathed a sigh of relief and said to the herald beside him.

"Yes!"

The general's order was immediately conveyed and the gong was sounded on behalf of the withdrawal of troops.

"Boom—"

Suddenly, there was a loud noise in the distance.

Suddenly, attracting the attention of the entire Sheng army, the retreating soldiers and generals turned their heads to look at that side.

"That's ...... The rumored army? ”

Deng Zhi was shocked, as a general, he was not as arrogant as those sour civil officials, after some inquiry, and asked those soldiers who had fought with each other, he knew that Cangguo had such an army.

Thinking of this, Deng Zhi immediately issued an order, telling the retreating soldiers to quickly organize a formation and prepare to face the battle.

After half an hour of effort, the Qilin Army took the shape of an awl and slammed into the Sheng army with a bad array.

In the past few days of fighting, the Qilin soldiers have a lot of experience, but the Sheng ** team attacking the city is nearly 200,000, and it is impossible to destroy them in one fell swoop, so the Qilin army adopted a roundabout way of attacking from the side, and quickly withdrew after killing for a while, leaving a group of infantry behind to stare dryly.

Rao is like this, and it also caused tens of thousands of casualties in the Sheng army, and the generals were so angry that they shouted.

It was a retaliatory engagement.

Through this time, the Sheng army finally witnessed the legendary Cang ** team in Cangguo, and behind the tens of thousands of casualties, there was a deep fear of the Qilin Army.

Time passes day by day.

On October 20, when Deng Zhi was still studying how to fight against the Qilin Army, a big battle finally ushered in on the border between Dong and Sheng.
