Bu An has never led soldiers to fight, but as a student of the Chinese department, he has read some history books to some extent, and some superficial truths are still understood.

For example, Sun Tzu said: Those who do not know the dangers of mountains and forests and the shape of depression cannot march, and those who do not use village guides cannot gain geographical advantages...... Therefore, it is as fast as the wind, as slow as a forest, as invading as fire, as immobile as a mountain, as difficult as a cloud, and as moving as a thunderstorm.

In this passage, two main points are made.

First, the march had to survey the terrain.

Second, the movement of troops should be fast and slow, concealed and powerful, and orders and prohibitions should be enforced.

For the first point, Bu'an has Zhang Blind and the other two feng shui cultivators in the black camp, not to mention the shape of the mountains and forests, frustration, that is, the choice of land, avoiding evil and seeking good fortune, dividing gold and fixing holes, and digging people's ancestral graves can be done easily.

It's just that this second point is a bit troublesome: it is not easy to let a group of people who were still eating in the rivers and lakes a few days ago be reckless, and not disturb the people and make trouble, and it is too difficult to do the order and prohibition, such as the command of the arm.

So, he's ready to start with a relatively simple start.

The first point is to maintain the formation between advance and retreat. This is like football or rugby, how the six battalions are arranged and what distance they maintain from each other needs to be run in and practiced.

The second is to practice the rapid march on the premise of satisfying the first point. As the saying goes, a soldier is fast. Since it can't be done for the time being, it is like a forest, the invasion is like fire, it is not moving like a mountain, and it is difficult to know like a yin...... Then make "its speed like the wind" to the extreme.

The next morning, the seven divisions and six battalions each sent people to buy military supplies, and Bu An himself found a money bank and exchanged a few large bills of five hundred taels into cash. A hundred catties of silver ingots, wrapped in a carry-on bag, his heart was not beating or panting, and he didn't take it seriously at all.

After eating at noon, more than 200 people from the Seven Divisions went to the street and went out of the west gate of Quanzhou. When encountering the soldiers on patrol, Bu'an lit up the talisman that Song Yinting gave him before parting, and the road was unimpeded.

During this period, Song Shijin always hung alone at the back of the team, a little alienated, but he did not fall behind.

When they arrived at the official road outside the city, the formation arranged by Bu'an in the six battalions was also the same, and they were no longer as banditry as when they left Yuezhou.

When the people who were hurrying past this procession, they all hurried with their heads bowed, and their expressions were quite cautious, as if they were calmed by the posture of these hundreds of people.

Bu An probably knew what level the average combat strength of the ordinary army under Song Yinting was, and he felt that this team composed of pure cultivators would have no problem resisting an army formation of one or two thousand people—of course, if the other party had a gun, it would be a different matter.

The team of the Seventh Division walked on foot for more than an hour, and the road became more and more rugged, and the surrounding mountains were already stacked.

Bu An came to the front of the team, instructed Zhang Blind to look for the southwest direction, and then said loudly: "The world's martial arts are only fast and unbreakable! The same is true for marching! You all work hard to move forward, don't fall behind!"

As he spoke, he turned his head and went into the mountains with Su Su.

Bu An had promised to team up with Song Shijin to brush up on the monthly order, but he didn't say that he would be his nanny before this, so he didn't worry about whether he could keep up at all - if he couldn't keep up, Jiang Ning would see him in three months.

After that, more than 200 people from the Seven Divisions finally crossed the mountains and came to Changtai County, Zhangzhou Prefecture, in the lower reaches of the Jiulong River estuary.

Song Shijin looks like a rich son on weekdays, and he didn't complain when he hurried overnight. The people of the Seven Divisions eat dry food and drink stream water, and they can lie down and rest in any mountain forest, and he does it all, it doesn't matter.

Although this keyboard warrior always seems to be very unsociable, Bu An's impression of him has changed slightly: this guy is probably really good at battle.

On the afternoon of November 20 in the second year of Longxing, the sun shone weakly on the ancient Changtai county wall. The officers and soldiers guarding the city saw from afar that the team was covered with mud and dirt and did not look like the attire of the officers and soldiers.

Bu An walked at the front of the team, holding a talisman in his hand, and shouted: "We are the Seventh Division of Yuezhou, and we came to suppress the bandits on the order of Lord Song of Song Yin Ting!"

A head peeked out of the city wall, scanned the nondescript team below the city suspiciously, and then shrank back after a while.

It was only after a long time that a group of officers and soldiers came out of the city on horseback and rushed to Bu'an.

The middle-aged man who looked like the leader in the middle took the talisman in Bu'an's hand, glanced at it, returned it to Bu'an, and said with a frown: "The Seventh Division of Yuezhou? There are no bandits here, no need to suppress bandits, you better go back. ”

This person's official speech is okay, and the Minyue accent is much less than that of ordinary villagers. Everyone in the Seven Divisions understood.

"You turtle son!" Lao Tzu went up and down the mountain, made him like a mud monkey, and hurried all the way to suppress the bandits for you! You said let's go back?!Where are we going back?!" Behind Bu'an, a short man shouted in a half-hoarse voice.

The people of the Seven Divisions were in a hurry day and night, and under fatigue, they were already irritable, but now that someone started, they couldn't help it anymore and shouted one after another.

"Lao Tzu is not going anywhere!

"Can't you Nanban understand people's words?

The leader of the officers and soldiers had a grim face, and said coldly: "This officer has been on an errand for so many years, and I have never heard of your team!

A young soldier behind him whispered: "General Zhang is stationed in Changtai, and the bandits dare not rob the township. It's ridiculous. ”

These few words of ridicule were like water dripping into hot oil, and they immediately fried the pan.

Bu An turned his head sideways and scolded: "Shut up!" only to temporarily suppress the excited team.

He guessed that the misunderstanding was false, the exclusion was true, and General Zhang in Xiaobing's mouth didn't know where he came from, and he estimated that he was not a person from Song Yinting. If it weren't for the middle-aged officer and soldier in front of him seeing the talisman, it wouldn't have been this reaction. The name comes by itself, and Changtai County will be squeezed out, and Song Yinting, an old oilman, didn't even inform him in advance.

Now, it is a little difficult to have the idea of entering the city, but not to lose face in front of his brothers.

"This brother Tai has misunderstood. You see that my talisman is not fake, right?" Bu An thought as he handed over the bronze talisman.

The officer and soldier took the talisman, stuffed it into his arms without even looking at it, and sneered: "Who knows where you picked it up." ”

Bu'an's face was flushed with blood, and his chest was burning with anger. The other party even dared to swallow Song Yinting's talismans, which made it clear that there was no room for accommodation.

But if you suffer this dumb loss, the hearts of the seven divisions will be completely scattered. This is obviously not a consequence that Bu'an can accept.

"......Someone is coming," he smiled, and pointed to the small group of officers and soldiers in front of him: "Take them all!"

"You dare!" The middle-aged officer and soldier obviously didn't expect this to be the result, and a trace of panic flashed on his cold face.

Behind Bu'an, someone had already rushed out, but he waved his hand. Everyone was a little puzzled for a while, not knowing whether to advance or retreat, and they all stopped moving.

"Brothers, this errand guy just said that he doesn't know our team. Come, who's going to tell him, let him remember it a little longer!" Bu An said loudly.

"Let's ...... Yuezhou Seven Divisions!"

"The ...... of the Seven Divisions of Yuezhou"

The crowd responded.

"Remember?" Bu An smiled at the middle-aged officer and soldier: "It's okay, I'll always remember it in the future." ”

With a wave of his hand, he said coldly: "Tie up!"

The crowd behind him rushed out like a tiger, and instantly overwhelmed this small group of officers and soldiers.

In the distance, in the direction of the city wall, there were several exclamations.
