Ma Hongbu set up the infantry hook line formation and continued to drive towards Hanzhong, because the terrain outside Hanzhong is changeable, mostly hills and paths, and the hook line formation is a convenient formation to change the formation. Since the Jingzhou army defeated the alien race, along the way Ma Hong's army advanced, and was not blocked by Zhang Lu's regular army, Ma Hong thought that Zhang Lu's army was very likely to defend the city, and would not go out of the city to meet the attack, when he heard the scout report, Yang Ren and Yang Ang led the troops out of the city to meet the Jingzhou army, Ma Hong smiled, the two men were defeated, there is no need to worry.

The army led by Yang Ren and Yang Ang camped according to the danger, and their army piled up hundreds of mounds of earth, which were about four meters high, and colorful flags were erected on the soil slopes, and the flags swayed in the wind. There are also seven large tripods placed in the mound, which are filled with clear water. In front of the slope are three trenches more than three meters deep and five meters wide. Its army occupies the high ground again.

The Jingzhou army drove to the front of Yang Ren and Yang Ang's formation, and the hook line formation turned into an infantry phalanx, with 1,800 people in the Zhao Yun phalanx arranged in the front, and behind the Zhao Yun phalanx was 3,600 people led by Gan Ning Wei Yan, and then the two wings were Huang Zhong and Ma Chao, Ma Chao 2,000 people, and Huang Zhong 3,000 people. Liu Qi and Liu Bei led an army of 6,000 people.

The generals saw Yang Ren and Yang Angbu descending the strange formation, and they all went to the trench to watch the formation. Wei Yan looked at the mound of soil piled up in the opponent's formation, and the flags planted on the mound said, "Why do you have so many flags?" When the Shroud? ”

Liu Bei looked at the scene in the field and was puzzled, although he had traveled south and north for many years, and he had fought a lot of battles, but he had never seen this kind of thing, is this kind of formation really a formation? The mound is to block the enemy's charge, the flag erected on the mound can predict the direction of the wind, and during the day, it can confuse the enemy's mind and make people unable to concentrate during the battle, what else is there? When the mound is used to block the enemy, it also blocks its own people, and if the enemy attacks the mound, what is the use of the archers standing on the mound?

Ma Hong looked at this scene, frowned when he saw it, couldn't help squatting on the ground, picked up a dry branch and drew a few times, and his brows furrowed even deeper.

"Zhang Lu is the leader of the Five Doumi Sect, and his style of acting should be similar to Zhang Jiao, and this formation should not be difficult to break." Liu Bei said to Ma Hong.

"If it's an imperial uncle, how can you break it?"

"I see this formation as just a boo, the array is full of mounds, and the pikemen can't use it when they enter the formation, if they send three thousand axes and shields, they can break it."

Ma Hong shook his head and said, "I don't think it's that simple, I need to confirm it." ”

Then Ma Hong found a big poplar tree not far away, and said to Li Yu: "Climb the tree and count how many mounds there are." ”

Li Mo shook his head and said, "I'm good at climbing trees, but I'm not good at counting. ”

Ma Hongleng paused, Wei Yan immediately walked out, and said while unloading his armor: "I'll leave it to me." ”

"Why did the advisor go to count the mounds?" Zhao Yun, who has always disliked words, couldn't help but ask.

Ma Hong smiled and said, "Looking at this formation, it feels familiar, let Wei Yan confirm it." ”

After Wei Yan climbed the tree, he came down from the tree after a while, ran to Ma Hong and said, "Military Division, there are a total of one hundred and one mounds, but there are seven big tripods in the mound. ”

Ma Hong nodded, also took off his armor, handed the sword and armor to Gan Ning, and then ran over and climbed the tree.

Wei Yan was stunned for a moment, and secretly said in his heart, since you want to climb the tree, why do you have to climb it first.

Ma Hong climbed halfway up the tree and looked towards the mound array, the flag fluttered in the wind, Ma Hong looked at it quietly for a while, the swinging flag had seven colors, and the seven-colored flag formed a word: Mou.

The corners of Ma Hong's eyes twitched, and he climbed down the tree.

Scheme.

Seven-color flags.

One hundred and one mounds, seven tripods. One hundred and eight, thirty-six heavenly gangs, seventy-two earth evils.

Is that him?

If it's him, it's really not good news.

Liu Bei looked at Ma Hong's face and walked over with a slightly dark face, and stepped forward and asked, "Military Division, what's the matter?" ”

Ma Hong took the Mou Broken Sword from Gan Ning's hand, then slowly pulled out the Mou Broken Sword, looked at the Mou Broken Sword and said, "You can't despise the enemy, because the enemy has my senior brother in the array." ”

"Xu Shu?" After listening to Ma Hong's words, Liu Qi immediately said.

Ma Hong nodded. Xu Shu with the banner cloth out of the word, is to invite him together to seek victory, the mound of the formation has the shadow of the stone formation of the Water Mirror Villa, the important thing is the seven colors, Ma Hong once Zhuge Liang entered the village to apprentice, had tested Zhuge Liang with the name of seven kinds of herbs, the name of the seven kinds of herbs contains seven colors.

Liu Bei already admired this eighteen-year-old boy, but when he saw that the young man now looked solemn and said that there was his senior brother Xu Shu in the enemy formation, Liu Bei couldn't wait to see what kind of person his senior brother Xu Shu was.

Huang Zhong on the side snorted: "I think that person is just playing tricks, Childe, you only need to give me 3,000 sword soldiers, and I will break this formation for Childe." ”

Liu Qi said: "General Huang is very earnest, I understand, I should wait until I return to the camp first, and then think about it in the long run." ”

Liu Qi rejected Huang Zhong without hesitation, what kind of joke did Ma Hong fear, how could Liu Qi let Huang Zhong lead his troops to take risks.

After Ma Hong returned to the barracks, he first sent out 800 round-headed shovels and rakes to let the soldiers dig three trenches two meters deep to lead to the enemy formation. Eight hundred shovels were made by craftsmen when Ma Hong was in Nanyang in order to facilitate digging of soil, and the iron-making technology of this era created shovels were not sharp enough, nor strong enough, and they were relatively easy to damage when used to dig soil.

The soil dug up by the sappers was used by Ma Hong to level the site, so that the twenty trebuchets could be arranged. If it is not possible to break the formation from the inside, the trebuchet will be arranged, and when the time comes, it will be completely defeated with the 3,000 fireballs made by Ma Hong. The three thousand fireballs were useless when attacking Chenggu, and I wanted to use them again when attacking Hanzhong City, but since I met Xu Shu, I couldn't act according to the plan anymore.

Whenever the wind rose and the flag fluttered to the east, Xu Shu asked the archers to stand on the mound of earth and take advantage of the wind to release arrows to hinder the Jingzhou army in the trench from digging a ditch forward. Ma Hong saw the move and laid a wooden plank on the trench to block Xu Shu's arrows. Ma Hong's aim was to dig through the three trenches with the enemy's trenches. Then fill in the soil in the three trenches to fill in the obstacles such as wooden thorns and knife formations arranged by the enemy in the trenches, and then dig the first trench and continue to fill the second trench. In this way, the Jingzhou army can charge as comprehensively as possible when charging and reduce casualties. If the enemy does not take the initiative to attack, it will not only reduce the number of attacks from archers, but also push the battle line forward. Once the trebuchet is in the right position, the attack is launched. [The trenches of the Jingzhou army were dug vertically, and the trenches of Zhang Lujun's were dug horizontally]

However, when the sappers dug through the enemy's trenches, Xu Shu actually opened the soil and released water, it turned out that Xu Shu dug a few ditches, and the water of the moat was passed into his own trench, when the trench was connected to the trenches of the Jingzhou soldiers, Xu Shu ordered the soldiers to open the soil and release water, and introduced the water into the trench to flood the Jingzhou army. This amount of water is not enough to drown people, but it can make the Jingzhou army unable to work in the water, and it can also control its movements. At the same time, Yang Ren and Yang Ang led their troops to rush out, intending to attack the Jingzhou sappers in the trench.

Under Ma Hong's orders, Zhao Yun went up to fight with Yang Ren Yang Ang, and Yang Ren Yang Ang saw that it was not enough to break through the Jingzhou army, so he retreated. Since the trenches dug by the Jingzhou army were filled with water, Ma Hong's plans had to be stopped.

Ten days later, the field has also been leveled, and all the trebuchets have been arranged, but because of the headwind, the trebuchets cannot attack the enemy camp by firing fireballs, and as the attacker, they will not attack for ten consecutive days. Huang Zhong has already asked for war nine times, and even Liu Bei has asked Liu Qi to fight. Just when Ma Hong agreed to test Xu Shu to enter the army. The enemy attacked it suddenly, and with great ferocity.

Xu Shu naturally also saw the trebuchet of the Jingzhou army, if he left it alone, once he was pushed into the range, although he had a soil slope to protect it, if the Jingzhou army took stones on the spot and constantly harassed them, it would definitely make the earth array chaotic. So Xu Shu will definitely not let the trebuchet continue to move forward. Under Xu Shu's arrangement, Yun Jin, the commander of the ghost pawns, led a hundred ghost pawns and 3,000 militiamen to form a death squad, and under the cover of Yang Ren and Yang Ang, attacked the Jingzhou army.
