The letter of war was sent by Meng Huo, accompanied by Meng Huo's oath. In this battle, Meng Huo wanted to capture Liu Yi alive, but would not kill him, but would release him, which was considered to repay the previous grace of capturing and releasing the four times.

"This Meng Huo..." Liu Yi shook his head, looked at Zhu Jian and handed it to Ma Su and said with a smile: "This time I'm a little arrogant."

Ma Su put down the bamboo slips and thought for a while and said, "Who Meng Huo relies on is probably the group of beasts in the Ba Na Cave. Does Mo Hou have a way to crack it?"

"Yes, I was originally prepared for another army, but now that I have caught up, I will deal with them first!" Liu Yi nodded. As for the vine armored soldiers... I don't know if they will come, but now it's important to deal with the beast group first.

Ma Su naturally didn't know which army in the south central area could make Liu Yi pay so much attention. However, since Liu Yi has designed weapons specifically for this army, it is difficult to deal with, but dealing with the beast group is the top priority now.

"Meng Huo has many soldiers and horses this time, and the barbarians seem to have some atmosphere. Now he takes the initiative to fight. Although the beast group is powerful, he doesn't have too many views." Huang Zhong frowned and thoughtfully said, "But since the barbarians do not have naval forces, why don't our ships go upstream and harass the enemy's rear and make them lose their positions?"

Although there were some military disciplines, Meng Huo's defeat last time was not just the blame for military discipline. Improper command was the biggest problem. Huang Zhong wanted to use the same trick again and attacked him again, so that the opponent could be disorganized.

"You can try it, but don't have too much expectations." Liu Yi did not refute. This temporary patchwork of naval army would definitely not be able to fight against the regular naval army, but there was obviously no naval army in the barbarian army's organization. This is a blank area and can be played out. Even if it is an irregular naval army, it is better than nothing.

Liu Yi asked the generals to prepare to face the enemy, and he ordered the craftsmen to assemble the wooden beasts. These things were prepared long before entering Nanzhong. They pulled them from Zhuti to Jianning, and from Jianning to Yunnan. They had squandered a lot of effort, and now they can finally be used.

If this thing is placed on a normal battlefield, it does not work much, or even has no effect. If you really want to set fire, you will rush into the enemy camp, bring some torches and hay. Why bother so much? It is only in the southern central area, which is made specifically for the purpose of defeating vine armored soldiers and these wild beasts. This has become a weapon on the battlefield.

Overnight, thirty wooden beasts in the mechanism were assembled and a lot of tinder oil was filled inside. If it was accidentally detonated, it would be a disastrous blow to its own side.

The next morning, Meng Huo was already commanding the army fiercely and scolding outside the camp. Liu Yi led the generals out of the camp. The soldiers of the three armies slowly opened the formation outside the camp. Driven by craftsmen, the thirty wooden beasts slowly climbed into the battlefield as the army slowly climbed into the battlefield. According to Liu Yi's instructions, they lined up in front of the army. These wooden beasts were driven by mechanisms, some of which were similar to the legendary wooden ox and flowing horse. If they were moved, they needed to operate. However, even so, the wooden beasts that could walk by themselves did not need to be pulled by others, still made many people watch sideways.

"What is that!" Meng Huo was ordering people to yell and curse. Suddenly, a large number of wooden beasts walked out of the other party's army, a little surprised and suspicious. He had never heard of wooden beasts that could walk around by themselves.

The barbarians around looked at each other, but they didn't know why the wooden beasts on the other side moved themselves, and they shook their heads in a daze.

"Your Majesty, don't worry, but just dozens of wooden beasts. I see that those wooden beasts are slow to act, and even if they are really used to charge into the battlefield, what's the point?" King Mulu looked at the wooden beasts in the enemy's army formation, shook his head and smiled. He had enough confidence in his ability to control beasts.

Meng Huo nodded when he heard this, looked at the enemy formation, patted the horse down. His curly red rabbit was shot to death by Huang Zhong with an arrow. Now he has changed to an ordinary war horse, and it is particularly awkward to sit on the horse's back.

The Han army's bows and arrows were extremely long, and Meng Huo dared not get too close. He took a deep breath between 140 and 50 steps, and almost roared at the other party: "Liu Yi, today, I will definitely capture you alive. If you still care about the lives of the soldiers under your command, you can quickly withdraw from Yunnan. I can guarantee you that there will be no trouble again!"

"What did he say?" Liu Yi rubbed his ears. It was too far away that he could only hear Meng Huo roaring there. Liu Yi didn't hear what he said, and looked back and forth.

Zhao Guang and Guan Xing shook their heads, but they didn't hear it clearly. Zhang Bao turned around and said, "It seems that he was going to capture Mo Hou alive?" At the end of the day, Zhang Bao was also a little uncertain. He didn't hear Meng Huo clearly, and the noise was too loud.

"This Meng Huo... Alas, if you succeed, you will be arrogant!" Liu Yi shook his head, a little disappointed: "Since he wants to fight, then fight and beat the drum!"

"Here!" The messenger agreed, waved the flag, directed the drum and trumpeter to start music and prepare for battle.

For a moment, the drums and trumpets sounded, and amid the desolate trumpets, the rumbling drums sounded with a surging force, spreading from afar.

In front of the opposite formation, Meng Huo heard the sound of the other party's drum trumpet, and his expression became ugly. He had a lot of contact with the Han people. He knew that this was the sound of the drum trumpet that the Han army was preparing to fight. He no longer talked nonsense to Liu Yi. He turned his horse's head and returned to the formation, looked at the Mulu King and said, "Brother Mulu, I will leave it to you next! I am responsible for commanding the charge of the three armies. Please let the bison start rushing to the formation!"

"Okay!" King Mulu had no intention of reconciling with Liu Yi. Otherwise, if he brought so many families, would he still be watching the fun?

Amid the strange sound of horns, three hundred bisons were driven to the front of the formation. In the strange rhythm, the bisons' eyes began to turn red.

It's just a sound, so naturally it won't let the bison do this, but with some medicines mixed in the forage before and with this horn sound, it can stimulate the bison to enter a manic state.

The bisons shook their four hooves and began to charge towards the opposite army formation. Meng Huo immediately ordered the most elite troops he had trained in the past period to rank the front, followed the bison formation forward, and the soldiers and horses in the rear followed in a mess. The gap between the untrained barbarians and the trained barbarians was revealed at this time. Not to mention that they were well-trained, but at least those trained barbarians could feel handy between advancing and retreating. As for the barbarians in the rear, they were mostly Mulu King. Meng Huo could command them, but they were obviously not as useful as these trained barbarians.

Huang Zhong's fleet began to flow upstream along the Xier River and fired arrows to the barbarians on the shore from afar, creating chaos behind.

In front of the two armies, more than 300 wild bisons were gradually starting to run. Although they had not yet accelerated completely, their momentum was suffocating!

Liu Yi nodded to Zhang Bao beside him. Zhang Bao understood and quickly waved the flag. Rows of soldiers ran to the front of the formation with hay and tinder oil on their backs, threw bundles of hay in front of the formation, forming a line, and then the soldiers behind came up and poured a jar of tinder oil on it. It sounded complicated. In fact, there were two rows of people, one row threw the hay to the ground, and the other row poured the tinder oil outward, spread it in one breath and ran back. At this time, the bison's acceleration process had ended. Although there were still dozens of steps apart, such a small distance might be one or two breaths.

A depressing aura came to my face, and the barbarians behind also launched a charge. Liu Yi pulled out his sword from his waist and raised it high, saying aloud: "All fire beasts, listen to my order!"

Fire beasts have a delay in spitting fire, but they cannot set fire immediately. To ignite the flames too early will only make the buffalo afraid and slow them down. What Liu Yi wants is to startle these buffaloes and let them charge in the opposite direction. This requires a grasp of the timing. The buffalo’s speed is just about to rise before the buffalo reaches the line of fire. With the sound of the gong, the buffaloes can turn back and sprint.

It only took one or two breaths, but it felt extremely long.

"Let it go!" Liu Yi's sword fell back fiercely, almost at the same time, a craftsman in charge of manipulating the fire beast mechanism moved the machine. There was a fire-induced device at the mouth of the beast. Liu Yi did an experiment, and the success rate was more than 99%, and the delay time was about one second.

"Huh~"

Thirty tongues of flames were sprayed out almost at the same time, and the hay poured with tinder oil in front of the formation burned with a whirlwind, forming a huge fire wall.

"Boom~" Several wild buffaloes couldn't stop and rushed in directly through the line of fire, but their butts were facing this side, and their four hooves were still digging and pulling back.

More than a dozen soldiers in the front row were knocked away, but the fire bulls on fire rushed back like crazy. Many bisons collided directly together, and the scene was a bit chaotic. Liu Yi couldn't see clearly through the fire wall, but the buffalo formation was obviously blocked. Liu Yi immediately ordered: "Soldiers of the three armies, kill!"

"Kill!" Yan Yan, Guan Xing, Zhang Bao, Yang Ren, and Chen Ergou each raised their weapons and commanded their soldiers, roaring and rushing out in front of them. The fire wall was not wide. A famous soldier roared and rushed over the fire wall. The scene in front of him was shocking. Many cows collided with each other, and some rushed towards the direction of the barbarian army like crazy. Many places of Meng Huo's barbarian army had been broken open, and bison was still rushing back.

Faced with such a scene, Meng Huo was also a little stunned. Seeing that the originally strict formation was shattered under the impact of these bisons, the Han soldiers following him ignored these things and slashed them with their knives. The formation in front of them was broken. Before the barbarians in the rear were suppressed, the barbarians in front were already defeated and fled. There were also bisons rushing around with the nose of the machine in the middle. The scene was so chaotic that it was unbelievable.

"Go away!" Meng Huo saw that something was wrong, his expression changed drastically. He didn't want to be captured by Liu Yi again. This kind of defeat had already been achieved. According to his experience, it was difficult for him to turn the tide. He brought the people he could take away and rushed to kill the defeated army.

"King, wait for me!" King Mulu was a little stunned. The script was not right. The most important thing was that he sat down and looked majestic, but he was not a specialty in escaping!
