Whether in history or in Romance, Cao Cao's army was defeated by fire. The only difference is that Zhou Yu did it in official history, and Zhuge Liang called out the east wind.

But has anyone ever wondered why Cao Cao's army was easily attacked by fire?

Since Cao Cao raised his army to resist Dong Zhuo, he has experienced many battles in the world. What kind of battle situation has he never encountered? How rich combat experience is he that he will be attacked by fire? They really didn't expect it, or simply thought there would be no east wind?

Cao Cao and his men could not be really idiots. They would be prepared for fire attacks no matter what season they were on the battlefield. Otherwise, they would not have swept the north and then had the general trend of unifying the world.

The only explanation is that when encountering a fire attack, the navy forces under Cao Cao could no longer stop the fire attack from coming.

The main force of the Cao army was northerners. As the saying goes, the ships and horses in the south. Northerners fought against southerners in the south, so naturally they were busy and had no upper hand.

Of course, Cao Cao was not a fool. He summoned the Jingzhou naval army that had fought fiercely with the Eastern Wu for many years and fought against the Wu army. But the result was that the Jingzhou naval army that was hasty convened was depressed and lost all its losses after many fierce battles, and was no longer able to compete with the Eastern Wu naval army.

Losing the barrier of the navy, the Cao army built on the shore was almost unable to resist when they encountered a fire attack. The other people's arson ships came from the water with the wind. How could they resist without the navy?

This fire not only burned down the best opportunity for Cao Cao to unify the world in a short period of time, but also burned down the best opportunity for the Central Plains dynasty to resist the invasion of the northern nomadic peoples.

If Cao Cao could unify the world at this time, no matter whether he would continue to be the prime minister of the Han Dynasty or simply abdicate himself to become the emperor. At least he would concentrate the power of the entire Central Plains instead of constantly consuming it in internal friction for decades.

As long as the Central Plains dynasty can be unified, the nomadic peoples in the north will never have the slightest chance.

In addition to this, Cao's army also encountered an enemy that was even more terrifying than the battlefield, that is, disease.

In this era, the south was filled with water and mountains and fields, and the mountains and fields were covered with dense forests. Most of the fish and rice towns in later generations were still in the original style at this time. Naturally, various diseases were endless.

Miasma and dysentery in the south are deadly diseases for northerners. The most deadly ones are snails, which are snails that are spread throughout the southern water network.

The reason why snails are said to be dangerous is that they carry the terrible schistosomiasis. If they are parasitic, they will suffer from schistosomiasis.

In the modern world, schistosomiasis has almost disappeared. There is no impression on everyone. However, before schistosomiasis is eliminated, it is an extremely terrifying infectious disease. After the parasite is transmitted through snails, extreme weight loss, ascites, giant spleen, vein opening of the abdominal wall, lung bleeding and other serious consequences will occur.

People who are parasitized will become thinner, but their stomachs become huge like pregnant women. This is caused by water accumulation in the abdomen and abnormal spleen enlargement. If it cannot be treated effectively, death will be the final outcome.

Schistosomiasis, dysentery, miasma, etc. The Cao army stationed in Red Cliff was attacked by biological and chemical weapons. With the medical technology of this era, there is almost no possibility of cure.

The first reason why Cao's army was defeated in the Red Cliff was the defeat of the navy, and the second reason was that the invasion of various diseases caused the northerners to lose their combat effectiveness on a large scale infecting diseases.

If Cao Cao had accepted Jia Xu's advice before and was not so anxious to go out, but chose to recuperate and train the navy and hoard supplies. At most two or three years later, the Cao army, who were ready to go south, would definitely be able to pacify the Eastern Wu in one battle.

Because both sides are not on the same level in terms of population, resources, land, general trend, military strength, wealth, etc.

Now Yan Fei understands why Cao Cao did not accept Jia Xu's opinion, because he was already complacent after unifying the north. He believed that the strength he had could conquer Jiangnan like a destruction. He could only wait until the navy was defeated and the disease was rampant. However, Cao Cao had to hold on for the sake of face and then take action.

Cao Cao was not Liu Bei at this time. He had enough strength to dominate the world, so he naturally did not comment on Yan Fei's words. If it were Liu Bei, he would have turned into a whimper and cried and shouted "Sir, I've taught me."

"Then wait." Yan Fei raised his head and drank the so-called wine similar to beer in Tongjueli. "When you beg me."

After defeating Liu Bei's army, the troops brought by Cao Cao did not rush across Changbanqiao. Only a small group of people were chasing Zhao Yun and were defeated by Zhang Fei on Changbanqiao. After that, Cao's army never went there again.

Cao's army rushed to a hundred miles and was very tired after the war. Moreover, there were more than 100,000 people and defeated soldiers on the battlefield to capture them, and they rushed to the single-plank bridge before chasing them. Almost no one was willing to do it.

Of course, the main reason is that Cao Cao has regarded Liu Bei, who has lost his territory, as a bandit, no longer treats him as an opponent, and does not urge the army to continue chasing him. Yan Fei had no intention of encouraging him at all. Because for a person like Cao Cao, if he doesn't suffer enough, he will never trust anyone.

"Prime Minister." After drinking and eating, Yan Fei said goodbye to Cao Cao who was blushing. "I still have some things to do, so I will say goodbye first. I will come back when the Prime Minister needs help."

In the next few months, Cao Cao's army will sweep across Jingzhou. The Eastern Wu side will also begin to prepare for the battle. Yan Fei has nothing to do if he stays here, so he might as well go and do his own business.

"Oh?" Although Cao Cao blushed when he drank, he was not actually drunk. He looked at Yan Fei with confusion, "Zihou is leaving? But I am not well received?"

"The Prime Minister misunderstood." Yan Fei smiled. "The Prime Minister's army is so powerful that it is no problem to sweep Jingzhou. There is nothing to do with me at this time. So I want to do some of my own affairs. When the Prime Minister needs it, I will naturally appear."

Cao Cao showed a look of displeasure. Yan Fei's subtext was very clear. It was okay for him to sweep Jingzhou, but he would encounter trouble later. This was naturally not a good thing for Cao Cao, who was proud and thought he could unify the world quickly.

"Well." Cao Cao nodded slightly after pondering for a moment. "After a meeting, I will report to the court. Please ask Your Majesty to appoint you as a partial general and serve the Han Dynasty."

Cao Cao gave Yan Fei an identity. In this era without an ascending channel, the title of this general was definitely priceless. With this identity, Yan Fei could easily go anywhere, and if he came to Cao's camp, he would not be rejected.

For Yan Fei, who had been a general and a national teacher, he naturally looked down on such a title as a general. Fortunately, he was not determined to be here. After getting the seal and official position, he said goodbye to Cao Cao and left.

"Prime Minister, why did you let him go?" Looking at Yan Fei's back as he walked away, Cheng Yu stepped forward and whispered, "If he had gone to Liu Da'er..."

"Hmph." Cao Cao threw down his sleeve hard. "What can I do if I don't let him go? Can I stop it?"

Cheng Yu was silent. Judging from the strong strength shown by Yan Fei, if he really wanted to leave, he would not be able to keep him. Even if he forced the army, he would not know how terrible the price he had to pay.

Cao Cao and Cheng Yu and others subconsciously thought Yan Fei was using a delaying strategy. Now, Liu Da'er had successfully escaped and was about to leave to find the guy with false kindness and righteousness. However, in fact, they really misunderstood Yan Fei, and he really didn't want to stay here and waste time.

In the next two months, Cao Cao would sweep Jingzhou and then advance to Jiangnan. Liu Bei would send Zhuge Liang to Eastern Wu, and after a quarrel, he would persuade Sun Quan to form an alliance and then resist Cao Cao together.

Cao Cao would lead the army to live in the Wulin area on the north bank of the Yangtze River, while Zhou Yu would station troops in Chibi on the other side. It would take another month before the decisive battle between the two sides would be.

In the past two or three months, has Yan Fei been following Cao Cao to eat and drink? He is not short of that food and drink.

So Yan Fei simply left and went to do his own business.

For Yan Fei, there is only one thing that can be called a serious matter, that is, looking for the Nine Dings.

Returning to the woods where the trailer was stored before, he opened the camouflage network and opened the space-time channel, and drove the trailer back to the African warehouse in the modern world. Yan Fei changed into a helicopter and came to the Three Kingdoms space-time again.

In the following period, whether it was Cao Cao's northern land, Sun Quan's Jiangnan, Liu Zhang's Western Shu or Ma Chao's Guanlong, the people often said with certainty that there were divine beasts flying by in the sky. The sound was like thunder, and the sound of dragon roar was faintly heard.

These people heard the roar of helicopters, and as for the dragon roar, people who like to add fuel to the fire will add it to their own minds.

Yan Fei drove around in a helicopter, and his purpose was naturally to find the Nine Cauldrons. But the problem was that even though Yan Fei ran all over China with the imperial seal in his hand, the imperial seal had no reaction at all.

If Dragon Soul had not said before that there were three Nine Cauldrons in this time and space, Yan Fei would have doubted whether there were really Nine Cauldrons in this time and space.

"Is it because the imperial seal was broken?" Yan Fei controlled the operating lever with one hand and held the imperial seal with the other hand and watched carefully in front of him. The gentle feel on the imperial seal was indeed very outstanding, but unfortunately there was no trace of heat at all. Yan Fei doubted whether this jade seal, which looked like the dragon ball radar, was broken.

"What's going on? Didn't you say there are three Nine Cauldrons in this time and space? Why did the imperial seal have no reaction at all? Could it be buried in the Arctic and Antarctic?" Yan Fei kept calling out to the dragon soul, wanting to get an answer from it. Unfortunately, the result was the same as before, without any response.

"This bastard." Yan Fei sighed, and his eyes looked through the porthole toward the earth below.
