Yi Jiuxiao decided to take Wan Shumad to the expedition together, because only war can train soldiers.

Although the army of a thousand mortals is still weak, after the baptism of war, it will eventually become stronger.

At noon on the second day, Yi Jiuxiao led 8,000 forbidden troops out of Gyeongju City and headed north.

There were eight formations of eight thousand forbidden troops, each with a thousand people.

Two of the formations were led by You Yu and Wei Ting, who had followed Yi Jiuxiao from birth to death, and cooperated with each other tacitly.

The 8,000 men selected the best horses, and the food, supplies, and magic weapons were packed in storage bags.

Except for one person and one ride, there is nothing superfluous. Therefore, the marching speed was very fast, and it was possible to march 600 miles a day.

Yi Guo's action was very sudden, without warning, and Zhou Guo did not know about it.

Zhou Dingqian, the emperor of Zhou, was furious at this time, because the sixth princess had escaped on Saturday and Saturday and brought back the death of the second prince Zhou Lei.

Since the founding of the Great Zhou State for thousands of years, it has always been the hegemonic side, and he has never been so humiliated.

Moreover, these two princes have always been deeply loved by Zhou Dingqian, and they are also the heirs to the throne.

In a fit of rage, Zhou Dingqian did not listen to Dazai's unwarranted dissuasion, beheaded Chen's envoy to Zhou, and displayed his body on the street for three days.

Chen not only stationed envoys in Zhou, but also distributed many Tanma in Zhou, and the news of the envoy's killing was soon transmitted back to Chen by Tanma.

Even so, Zhou Dingqian was still angry, and ordered Shangshu Yanguang of the Ministry of War to dispatch 100,000 soldiers and horses to use troops against Chen Guo from now on.

The two countries competed with each other, and if they did not kill the envoys, since they killed the envoys of Chen State, it was clear that they wanted to start a war with Chen State.

Originally, Zhou Dingqian hated Yi the most, because the combined forces of Zhou and Ning were defeated by Empress Li Rong, and almost all the troops were wiped out, losing tens of thousands of horses and a few Jin Dan.

But now in comparison, Chen Guo is more hateful than Yi Guo.

Zhou Dingqian deliberately showed favor and intended to be friendly, but who knew that it would be such a result, how could he bear it!

So there was only war, and Zhou Dingqian decided to use war to dissipate the hatred in his heart and wash away the humiliation in his heart.

Those seeds planted by Yi Jiuxiao finally germinated, and the situation in the entire continent suddenly became very weird.

In the end, who will be the sandpiper and who will be the fisherman?

Yi Jiuxiao decided that he would be the sandpiper, the toucan that took the lead, and he wanted to ignite the war first.

The 8,000-strong forbidden army formation galloped north, passing through prefectures and counties along the way, but no one knew where it was going or what it was going for.

Yi Jiuxiao did not go with the team, he chose to fly, and it only took seven days to fly to the border of Bazhou.

Bazhou is a state on the border between Yi and Zhou, with a border length of more than 2,000 miles and an army of 50,000.

The main general's name is Yunfei, and the third layer of Jindan is cultivated. The two deputy generals are named Yu Yishan and Yu Yishui, they are a pair of brothers, and they are both Jindan second-level cultivators.

These three are all generals who have been guarding the border for many years, and they are quite familiar with the border and the Zhou State.

So Yi Jiuxiao decided to come over first and find them to understand the situation at the border gates.

The art of war is cloudy: know yourself and know your opponent, and you will not be defeated in a hundred battles. Only by knowing everything about the other party can you know how to arrange your troops.

He was different from the last time he went to Guzhou, he did not change his disguise, but flew directly into Yunfei's Guancheng and landed at the gate of the General's Mansion.

Although Yun Fei had never seen Yi Jiuxiao, he was already familiar with Yi Jiuxiao's name, and hurried out of the house to greet him after receiving the sergeant's report.

Although he also has a third-rank official rank, Yun Fei knows that he can't compare with Yi Jiuxiao, and in his eyes, Yi Jiuxiao is the same as the emperor.

After entering the General's Mansion, Yi Jiuxiao still took out Qi Qingru's edict, which is a rule, called justification.

Hearing that he was going to attack the Zhou Kingdom, Yun Fei did not show any nervousness or fear.

On the contrary, he was still a little excited, which made Yi Jiuxiao appreciate it very much.

The border guards are most afraid of the kind of people who are greedy for death and afraid of life, those people dare not fight, and they can't win the war.

Although Yunfei was very calm about the upcoming war, he was very cautious in introducing the situation at the border gates.

I only heard him point to the border map and say: "Lord Yi, on the border of Bazhou, although it borders more than 2,000 miles with the Zhou State, there are only three places where there are really roads, and the total is only a few dozen miles, and the rest of the places are dangerous places, and the brigade of people can't go through them at all." ”

Listening to Yunfei's introduction, Yi Jiuxiao felt that the border of Bazhou was different from the border of Guzhou with Chen State, and there were too many border roads in Guzhou.

"General Yun, how did you defend these three intersections, and how much strength did the other side have?"

"Returning to my lordship, I and the two lieutenants will each guard a pass in Yishui and Yuyishan. I was in the center, with 20,000 horses, and 15,000 men in one water and one in one water. As far as I know, the distribution of generals and soldiers on the Zhou side is similar to ours, maintaining a state of balance. ”

Yi Jiuxiao nodded and asked, "There is only one guard at each pass, and there are only 20,000 soldiers and horses, but how is the attack?"

"Lord Yi, it's not easy to attack, the cities on both sides are built in dangerous places, easy to defend and difficult to attack, it is difficult for the attackers to form a queue, and they are blocked by the city wall, so it is difficult to approach. Unless several Jindan monks are dispatched, they will fly over the city at the same time and attack the defenders on the city from the air, but less than five Jindan masters will have no effect. ”

Listening to what Yunfei said, Yi Jiuxiao felt that it made sense.

This cultivator seems to be very magical, wind, fire, thunder and lightning can be emitted, but these tricks can kill people, but they have no effect when used to attack the city.

The walls of Guancheng are ten zhang high and two zhang thick, and it is difficult to leave traces on the flying swords of those qi refining cultivators.

It is not powerful unless it is formed into a sword formation, but the sword formation of a thousand people must form a queue.

In Yi Jiuxiao's opinion, the monk army was not as effective as the rolling wood and stone and cloud ladders of the Great Song Dynasty in the previous life.

"What methods did you use to attack the city in the past?" Yi Jiuxiao asked after thinking for a moment.

"In the past, when we attacked the city, we used a large group of men and horses to attack, the air and the ground at the same time, a few Jindan in the air, tens of thousands of troops on the ground to carry out a strong attack, the defenders in the city were slowly exhausted, but the result was several times the casualties of the defenders. ”

Yi Jiuxiao secretly thought: What is the way to do this, he can't afford to consume such a large casualty now, whether it is the number of troops or the number of Jindan monks.

So he said: "General Yun, I already know what you said, and I will personally go to Guancheng to investigate it later, and then we will discuss and decide." ”

Anyway, the army is still on the way, and it will take at least seven days to arrive, so there is no need to rush, it is better to hear than to see, and it is better to investigate it yourself.

Yi Jiu flew over the open area between the two countries, which was a buffer zone, fifty miles long, with a seven-foot-wide dirt road in the middle, which could only be used by a horse-drawn carriage.

The Guancheng on the side of Yi is called Zhenbei Pass, and the Guancheng on the Zhou side is called Zhennan Pass.

The names of these two gates are very interesting, but on the contrary, it is clear that they are competing against each other.

Yi Jiuxiao didn't approach Zhennan Pass, but just watched from a distance, so as not to arouse the vigilance of the defenders of the Zhou State opposite.

Anyway, the pattern of the two sides of the city is the same, so the effect of watching the Zhenbei Pass in the country is the same.

The city of Guanguan in the north of the town is five miles long and wide, and the whole is square.

The height of the city wall is ten zhang, and there is no gate in the east and west directions, but there is only one gate in the north and south directions.

The south gate was very spacious, and there was a two-mile-wide open space outside the gate.

Beyond the gate to the north, there was only an open space less than five feet square, and then a seven-foot-wide dirt road stretched into the distance.

As Yunfei said, this gate is easy to defend and difficult to attack, and Yi Jiuxiao couldn't help but sigh when he stood in the air.

However, there is a way to solve everything, and he doesn't believe that this gate can only be attacked and shaken.

Subsequently, Yi Jiuxiao flew to both sides of the city, only to see that both sides were lofty mountains and mountains, and the dense forests and deep streams were inaccessible.

In such a terrain, horses will definitely not be able to pass, but people can still pass.

Yi Jiuxiao remembered that he was collecting medicine in Luowu Mountain, and the terrain there was also very steep, and he could still climb into it.

It can only be said that the monks of the mainland countries are well-pampered and rely on horses to travel, and they must carry a lot of baggage when they go out to fight, resulting in slow marching and poor mobility.

If you forcibly open a road in the mountains, then abandon your horses and cross the deep mountain stream on foot, you can bypass the dangerous fortress.

Horses are only the strength of the monk's feet, and they do not help the monk much.

Therefore, the loss of horses will only affect the speed of marching, and will not affect combat effectiveness.

In the process of crossing the lofty mountains, even if they are discovered by the enemy army, it is okay to fight in the dense forest, and with the personal combat strength of the forbidden army, they are simply afraid of the border defenders.

If you don't notice it, or the other party doesn't pay attention to it, then take a detour to the north gate of Zhennan Pass and attack from the north gate.

If the north gate of Zhennan Pass is empty, the forbidden army will form a sword formation in it, and then the attack will be easy and successful.

Thinking of this, Yi Jiuxiao had already made up his mind, he only needed to determine the pattern outside the south and north gates of Zhou Guozhen to Yunfei.

When Yi Jiuxiao told Yun Fei his thoughts, Yun Fei was very surprised.

He didn't even dare to think of this method before, and he believed that other generals didn't dare to think about it either.

Although Yun Fei didn't dare to think about it, he was not optimistic about this set of tactics, but he had to listen to it, and as a soldier, he had to obey.

So after listening to Yi Jiuxiao's thoughts, Yun Fei said: "Lord Hui, our army's Tanma once went to the South Pass of Zhou Guo Town in the caravan, and the north gate of the South Pass of the town is boundless, which is much more open than the outside of the North Pass of my town. I don't know if the adults decided to adopt this plan, but if so, the last will be willing to comply"

Yi Jiuxiao smiled and said, "General Yun, don't worry! This is a new set of tactics, let them try it when the forbidden army arrives." You will keep this method secret for the time being, don't talk to anyone, I'll think about the details. ”

Don't let Yunfei do it, on the one hand, beware of the lack of combat effectiveness of the city defenders. This jungle battle requires a high level of personal cultivation for the sergeant, and the forbidden army is more suitable.

In addition, Yi Jiuxiao knew that Yunfei was not very optimistic about his set of tactics, and obedience was only afraid of his authority, not recognition.

Although he is famous in Yi Country, there are not many people who have fought side by side with him, only Li Rui and those forbidden soldiers know.

So he wanted to use this battle to establish his prestige and make those generals of Yi really convinced.
