Cao Liang shook his head and said: "No, besides, how could I cross Xingshi Mountain and set fire to the back of the mountain, unless I had wings."

Xiahou Ba was shocked. Originally, Cao Liang had come up with this fire attack plan. Others would never have thought of it. If Cao Liang had not sent people to set fire to the back mountain, how did the fire in the back mountain burn? Could it be Shu?

Can’t people let it go on their own?

Cao Liang quickly climbed to the top of the mountain. From here, he could see the whole mountain behind Xingshi Mountain. However, the fire set by the Wei army had already burned over the top of the mountain and was spreading towards the back mountain.

There, a raging fire also broke out, igniting the entire back mountain. The fire was no less powerful than the fire in the front mountain.

There is a green area between these two fires, and the fire in the front mountain is spreading and eating away at this green area.

Cao Liang only took one look and understood, "Master, there is a master hidden deep in the Shu army."

The most effective way to deal with forest fires is to establish a fire isolation zone, that is, to clear away trees and ignition materials in the direction of the spread of the fire. When the fire burns through this area, there will be nothing to burn, and it will naturally be extinguished.

The most terrifying thing about forest fires is their spread. As long as there is a large forest, once a fire breaks out, the entire forest land will often be burned.

Fire isolation belts are used to prevent the spread of fire at the minimum cost. Generally, fire isolation belts are manually cleared. Depending on the fire situation, they are usually tens of meters or hundreds of meters long. When the fire burns here, there will be no flammable

The fire can no longer spread and the fire can be controlled.

Obviously someone in the Shu army understood this truth, so he set a fire on the back mountain in advance and burned the forest land in the back mountain. Under the same east wind, the fire in the back mountain also moved westward.

If the fire spreads in the back mountain, the fire in the front mountain will be unsustainable.

In fact, under normal circumstances, artificial felling is used to create isolation zones, so as to prevent forest fires from spreading again.

However, it is obvious that the Shu Army cannot consider this issue, so they will adopt the simplest, crudest and most trouble-free method to create an isolation zone.

Cao Liang frowned. As a result, another variable appeared in the capture of Xingshi Mountain. Originally, according to Cao Liang's plan, the Shu army would retreat to where the fire burned, while the Wei army followed Huotou and put out the fire.

The burned areas are controlled, so that the Shu army retreats again and again until it exits Xingshi Mountain. The fire will no longer be able to burn to the plains and will be extinguished automatically. The Wei army can follow the fire and control the entire Xingshi Mountain.

.

But now it has become a foregone conclusion that the Wei army captured the front mountain, and since the fire isolation zone was established in the back mountain, the Shu army can enter the isolation zone when the fire in the front mountain reaches the isolation zone, and there is no need to withdraw from the back mountain.

In this way, after the Shu army lost the front mountain, they could continue to occupy the back mountain. This is equivalent to half of Cao Liang's mission, taking down the front mountain of Xingshi Mountain. Then the back mountain was burned down by the Shu army. Cao Liang

The other half of the task can no longer be completed.

Seeing Xiahou Ba's overjoyed look, Cao Liang couldn't help but remind him: "Xiahou's army, don't be happy too early. The fire in the back mountain is not what you imagined. It was a fire set by the Shu people themselves. After the fire,

, the fire in the front mountain can no longer burn to the back mountain, so the Shu army did this deliberately to protect the back mountain position."

Xiahou Ba suddenly realized this. He had never understood how the back mountain could catch fire before, but he finally understood after hearing Cao Liang's explanation.

Xiahou Ba was extremely happy when he first saw the fire in the back mountain. He thought that if the fire attacked from both sides, the Wei army would be trapped in the fire and all of them would be burned to death.

In fact, Xiahou Ba did not think of a common sense. This fire must be achieved with the help of wind. If the fire wants to attack from the front and back, it will have to blow from the east wind and the west wind at the same time. This is obviously completely impossible. At this moment, all the east winds are blowing.

, so the direction of fire spread is to the west.

If Xiahou Ba looked again at this moment, he would indeed find that the fire in the back mountain was spreading towards the west, and the black area after the fire could be vaguely seen.

It seems that what Cao Liang said is absolutely correct. The fire in the back mountain was indeed set by the Shu people themselves. In this way, the Shu army will definitely hold on to the back mountain of Xingshi Mountain. The Wei army wants to use the fire to attack Xingshi Mountain.

The hope of capturing all the mountains was lost. Next, we had to fight with real swords and guns.

Xiahou Ba immediately issued an order to the Pioneer Battalion to prepare for battle. The Pioneer Battalion's swords were unsheathed, arrows were in the strings, and they were fully alert, always ready to go into battle.

┄┄┄┄┄┄┄┄┄┄┄┄┄

Liu Min almost trotted all the way and came straight to Wang Ping. She said out of breath: "Captain Wang, what's going on?"

"What's going on?" Wang Ping asked calmly.

Liu Min pointed at the raging fire in the back mountain and said: "The king has set fire to the forest land in the back mountain. So where is our army's retreat? Is it possible that we will all be trapped here and die?"

Wang Ping said in a deep voice: "What retreat do you want? We are still in the position, and I swear to live and die with Xingshi Mountain!"

Liu Min was shocked by Wang Ping's generous momentum. Wang Ping's words were indeed domineering. He was on the battlefield and vowed to live and die together on Xingshi Mountain. But could the fire burning from the front mountain be blocked with an oath?

Liu Min smiled bitterly. If he fought with the enemy, he would have such blood and courage, but facing the blazing fire, his flesh and blood body would really be unable to compete.

"Commander, the last general..." Liu Min said bitterly.

Wang Ping smiled slightly and said: "It is true that I will live and die with Xingshi Mountain, but I will not let the soldiers make unnecessary sacrifices. Liu Hujun, please look here."

As he spoke, Wang Ping raised his hand and pointed at the burned woodland behind him.

The original lush mountain forest was gone. Where the fire spread, there was already a scorched earth, with only sporadic flames burning continuously.

Liu Min's eyes widened, and he seemed to understand something.

Wang Ping said: "If you put it to death and live later, the burned mountain forest will definitely not burn again. Therefore, when the fire in the front mountain arrived here, it burned the forest land in the back mountain first, and waited until the fire in the front mountain later."

When the fire comes, all our troops can retreat to this burned area, and their lives will be safe, and their positions will not be lost."

Liu Min was full of emotions. To be honest, they all looked down on Wang Ping, who didn't know a few characters. They thought he had no knowledge or talent and only relied on brute force to achieve his achievements. Now it seems that everyone is wrong.
