Li Su's plan to "we level the valley roads between Yunnan County and Yuyu County, and wait for Ailaoyi to sit still to provoke" was not directly achieved by "detonating the war between the two sides".

He started to build roads in Yuyu County around the fifth day of the second month. However, as we all know, in the areas of border areas such as Yunnan and Yuyu, the areas bordering counties are often the poorest and most remote areas.

So it took Ailaoyi seven or eight days to get the news, and another four or five days to react and send people to obstruct the scene. Therefore, it was already late February that the conflict between the two sides was approaching.

Whoever made the county towns of these two counties two hundred miles apart, and the border line to the county town of Yuyu County is 140 miles (that is, the county town of Yunnan County is 60 miles from the border).

The border between the two counties is a mountain range, which does not even have a name now, but it is quite famous in later generations, called "Wuliang Mountain" - those who have read "The Legend of the Dragon and the Eight Parts" should be familiar with this place name, because in Jin Yong's writing, there are Wuliang Sword Sect and "Langhuan Jade Cave" on Wuliang Mountain, which contains the statue of the fairy sister and the secret book of Lingbo Weibu.

Wuliang Mountain moves north and south, and the ridge that crosses the northern section of Wuliang Mountain is Yuyu. There is a small river on the slope of the eastern slope, which eventually winds into Erhai Lake along the valley - and Yuyu County is on the west coast of Erhai Lake.

The soldiers of the Zhurong clan came to the site to stop the construction on the morning of February 20th.

At that time, the Han army had built the road more than 30 miles west of the Wuliang Mountain ridge, and it was a simple dirt road that elephants stepped out and crushed with elephants. Calculate the mileage, if you build more than 100 miles forward, you can lead to the Erhai Lake.

Because the section close to the ridge is steeper, in the future, I can only pass a wheelbarrow, and a four-wheeler that cannot pass a cow or horse, otherwise it will be easy for the car to stop when going downhill.

Li Su considered rebuilding the road into a winding mountain road with N consecutive bends on the section near the ridge to reduce the slope by imitating the "Qinglong Twenty-Four Turns" on the road, but in the end, it was because the project volume was large and did not conform to the construction habits of Han Dynasty craftsmen, and no one could design or survey it specifically, so he had to give up.

At that time, you can only use a cattle and horse cart to pull the cart to the foot of Wuliang Mountain, then replace it with a wheelbarrow and climb over Wuliang Mountain, and then change it to the foot of the other mountain. Although there are two more loaders and unloaders, it will save half the shipping fee than transporting carts throughout the wheelbarrow.

The generals sent by the Zhurong clan were just the cave owners of a small tribe. They brought hundreds of people. First, they mainly stopped the construction, pushed the Han soldiers to continue to advance, and shouted:

"This place is already in the vast Shanxi. Since ancient times, it has been the territory of Ailao tribe. You and the Kunming thieves quickly retreated to Wudi Shandong! If you dare to take another step forward, you will invade my Ailao territory!"

The Han army construction team followed Li Su's advance instructions and did not kill people directly. Instead, they insisted on construction and verbally insulted and refuted each other:

"We are here to build roads and trade, not for transporting troops, so why not do anything? We are going to go to Buwei County, Yongchang County to trade. Buwei County is still a place under the jurisdiction of the Han county magistrate. Is it wrong for the Han court to transport goods to Buwei County? If you dare to obstruct it, you are trying to besiege Buwei County as an enclave and regard it as an enemy of the Han court!"

After beating for a while, the two sides couldn't help but start fighting each other with old fists. There were many people on the Han army's construction team, and it seemed that they were prepared. There were many warriors fighting with force. In a short while, they beat Ailaoyi's obstruction team to the ground for teeth.

Ai Laoyi was so angry that he drew his sword and started slashing.

The Han army construction team quickly maintained great restraint and retreated one after another, and then rushed forward like a fierce rush.

There is no need for murderous weapons, just use an elephant pushing the rolling roller to press down the valley downhill road. With one charge, seven or eight Aila soldiers were killed by the elephant legs and the stone roll.

When Ai Lao soldiers saw that the other party was really coming, and there were more people, they hurriedly ran back to report the news. The Han army rushed the elephant to chase and explained: "Misunderstanding, misunderstanding, we are not going to kill people, this is a construction accident, and the construction elephant was frightened!"

After chasing and trampling on the ground for several miles, he finally controlled the frightened elephant and retreated.

Five days later, he was completely angry and brought the cave master for a lifetime, and sent the cave master from a small tribe to bring 5,000 elite combat soldiers from the headquarters to Wuliang Mountain to avenge the casualties.

Before sending troops, the Lord of the Caves of the Caves of the People's Republic of China also asked for the same tribes to share the same hatred. However, the diplomatic propaganda of the Han army seemed to be more powerful, and people had already spread news in advance that the Wuliangshan Incident was just a construction accident, so the other Ailao troops were stabilized for a while and wanted to wait and see, but refused to send troops together, so the Lord of the Caves of the People had to work alone.

In addition, although the advance team of the Zhurong clan was trampled to death by the construction elephant of the Han army, the cave owner did not use their war elephant troops to retaliate on a large scale.

The main reason is that the Wuliang Mountains are too rugged and steep, and they are only suitable for large-scale combat of mountain light infantry, and elephants can only accommodate a dozen at most. They also know that there are very few elephants in the Han army, and they are all sent to build roads and cannot form a formation scale.

The owner of the cave was considering "killing all the Han construction teams in one fell swoop, destroying the construction facilities, and retrieving the site." It was enough, and he did not want to destroy all the Han army with this little man.

Unfortunately, the development of things was completely different from what he imagined. He thought it was a "local conflict in road construction confrontation", and the Han army's vigil had already replaced cannons.

On the way to climb the main ridge of Wuliang Mountain along the valley, the five thousand Kunming Yi barbarians led by Meng Xin were ambushed on the hillsides on both sides, and the two thousand Han soldiers led by Gao Shun were intercepted by the "quasi-stopping camp" on the front.

After a fight, Ailao Army was defeated and came to annihilate the 5,000 people from the construction team. Not only did they not find a hair in the Han army construction team, they were almost destroyed halfway. There were more than 1,000 casualties, more than 2,000 were captured, and only the last one thousand escaped.

A provocation-ambush battle on Wuliang Mountain directly caused nearly 4,000 young and strong people to lose to the Zhurong clan, and they were all relatively elite combat soldiers, with quality far beyond the level of subsequent temporary mobilization and elimination of strong men. This greatly weakened the overall combat effectiveness of Ailaoyi in subsequent battles.

However, with this heavy blow, both sides were completely dismantled, and they no longer considered the possibility of diplomatic compromise or false conspiracy. They could only fight hard.

After bringing the cave master to gather the defeated soldiers, he once again asked King Mulu and King Wugo to help him with all their strength. For the sake of his lips and teeth, the two barbarian kings brought elite troops from their clans to join the alliance, while other smaller tribes were all on the excuse of waiting and not wanting to wade into this muddy water.

The three major tribes had a total of 500,000 Ailao people and 140,000 strong men. According to the five tribes, they should have 28,000 troops. After losing 4,000, they only had 24,000 troops left. However, because it was an inside defense battle, the cave owner had exhausted the lake and fished forcibly drew 6,000 more strong men who had never fought a war from his tribe, gathered 30,000 troops to defend Yuyu County.

After the troops were gathered, the Lord of the Cave and the two barbarian kings began to discuss how to fight this battle.

King Mulu was the one who had no idea in his heart. He was tied up with the chariot of the Zhurong clan from the beginning, but now he has been a little shaken. He said worriedly: "The Han army and the Kunming thieves join forces. Although the troops are not large, the Han people are strong and powerful. Unless we defend the city to the death or use our advantages to fight in dangerous and remote places in the mountains, we may not be sure to kill one of the three of us in the field."

King Wugo was more confident than King Mulu, and said proudly: "Hmph, you will only increase the ambition of the Han thieves! The Han thieves have the strength of iron armor. My Wugo tribe has the strength of vine armor. Even if it is not as good as the iron armor, the number is far from comparable to the iron armored soldiers of the Han army! The Han army had one or two thousand iron armors and died. Our 10,000 people had five thousand pairs of vine armor, which was just invulnerable! What's the harm in fighting in a dignified and straight field!"

After all, this is the real world rather than the Romance, so King Ugo is not so fantasy that he believes that the vine armor is far better than the iron armor.

It is just that the defense effects of the two are not much different, but the vine armored soldiers are in the cheap energy production, and they will not rust and can accumulate production for many years. Therefore, his tribe can only take out five thousand vine armored soldiers in one breath, hoping to use a scale to pile up one or two thousand iron armors to "quasi-stricken camps" of the Han army.

After boasting about the vine armor, King Wugo also encouraged his colleagues and said, "Although you do not have the benefits of vine armor, but if your troops add up, are those two or three hundred war elephants vegetarian? The reason why the Wuliang Mountain lost the battle was that the terrain of Wuliang Mountain was rugged and was not suitable for large-scale formation and trampling on the war elephants.

Since this is the case, how can we let the Han army come in? Put Li Su and Guan Yu in the open land on the shore of Erhai Lake to form a decisive battle. Let’s use the vine armored soldiers to fight with elephants, and trample on the Han army to death and wipe out all the Han army!”

King Mulu thought for a while: "But the Han army conquered the Kunming thieves, and Mengchang also had more than 100 war elephants under his command. If we use war elephants, they also used them. Our number was nearly twice that of him, but we could not say that this benefit was exclusive to our army.

In addition, if the enemy and I have all set up a war elephant, Brother Ugo, your vine armored soldiers will be of smaller place - the most important thing is that the strong armor is afraid of blunt weapons and huge force. No matter how strong the armor is, if it is stepped on by the elephant legs, all sentient beings are equal."

King Ugo: "If the enemy and I really set off a battle elephant, then I will definitely not be able to go to the first round. Our Ugo warriors will serve as a reserve team. When the elephant soldiers of both sides fight to decide the outcome, the battle elephants of Mengchang Dog Thief will be suppressed and killed. I will lead the vine armored soldiers to charge and cover them up, and you will win a complete victory."

The three of them discussed the details again and felt that it was very operational, so they decided not to set up defenses in Wuliang Mountains, and directly stepped back to the Yiyu County to show weakness. They forced themselves to put the Han army and the Kunming Yi coalition on the shore of Erhai Lake to fight to the decisive battle.

...

"Governor, General Guan, since his defeat in the middle of the night before yesterday, the master of the cave has given up defending Wuliang Mountain and has been retreating back to the Yiyu County. He also contacted King Mulu and King Wugo's main force to gather troops to assist in the defense of Yiyu County.

According to investigations, the elite main forces of King Mulu and King Ugo are among the reinforcements, so a large number of elite warriors and war elephants wearing strange armor were found in the enemy."

The mobilization of tens of thousands of enemy troops must be impossible to hide, so the general mobilization of the Ailaoyi tribes was soon intercepted by Li Su's scout.

Li Su and Guan Yu, who had been stationed in Wuliang Mountain for several days, finally felt that they could move forward with confidence.

"There are war elephants and vine armored soldiers? They are all gathered together? This is why I can't walk more and go to poor places with mountains and ridges to fight one by one, so do I gather together to send them away?" Li Su's smile couldn't help but gradually become abnormal.

He immediately ordered: "Tell Meng Xin that he can only bring five thousand mountain soldiers to help with our army. I have a kind heart to take his dozens of war elephants, but I don't need to bring them."

The messenger immediately went to communicate with the news, but Guan Yu next to him was shocked when he heard this: "The enemy has a fierce giant beast like a war elephant, which is hard to defeat. Why does our army not even carry a war elephant at all?"

Li Su: "I'm afraid of scaring our own war elephant. But don't worry, I will be fully prepared. We are not in a hurry to fight to the final battle. We will spend a few days preparing some things."
