Cao Liu and his entourage led the army into the city gate slowly. Riding in the city gate, Xi Zhicai carefully observed the surroundings, and suddenly smelled a faint smell, and his heart tightened.

"Lord, do you smell a faint smell?" Xi Zhicai said.

"What does it smell like when the army marches and the dust rises? However, the smell of horse manure is stronger. Cao Cao was puzzled.

"That's not right!" As a top strategist, Xi Zhicai is not only as careful as a hair, but also has many stronger five senses than ordinary people, and he did smell a familiar smell just now.

"Zhicai, is there anything unusual?" Cao Cao asked.

looked around, and really didn't find anything unusual, the smell just now had disappeared, and the vigilance in Xi Zhicai's heart was slightly relaxed.

"There's too much horse manure around the gates! Could it be that Li Dao and Guo Yan sent troops to Tongguan again? Looking at the large amount of horse manure on the ground on both sides, Cao Cao frowned.

"Impossible, the danger of Tongguan is no less than that of the Tiger Prison Pass back then. The Xiliang soldiers were not good at attacking fortifications, and our army was stationed with General Xiahoudun and 20,000 troops, and there would be no incident. Xi Zhicai said.

"Well, what Zhicai said is good. Li Dao and Guo Yan even abandoned Chang'an, and they didn't dare to attack Tongguan. How similar is the situation now to the time when Dong was being discussed, how can the traitor flee westward, how dare he go and return? Cao Cao said with a smile.

"Huh?" A light flashed in Xi Zhicai's mind: "What did you just say, lord?" ”

Cao Cao was stunned for a moment, and then said: "I said that Li Dao and Guo Yan did not dare to attack Tongguan, and now the situation is very similar to that of Dong back then." ”

"Ask for Dong? Asking for Dong? Xi Zhicai muttered to himself, as if he had thought of something. Suddenly, he remembered what he had just smelled and suddenly shouted, "Not good! Lord, we have been tricked, quickly order the whole army to withdraw from Chang'an! ”

"What?"

"The smell I smelled just now, although it was very faint and muffled by the smell of horse manure, was definitely fire oil! Li Dao is planning to burn Chang'an again! Xi Zhicai shouted.

"Miaocai, order the whole army! Withdraw from Chang'an immediately! Evacuate! Cao Cao's pupils shrank in his eyes, and he hurriedly shouted.

Although Xiahou Yuan was puzzled, seeing Cao Cao's eagerness, he hurriedly ordered: "The army stops!" U-turn and withdraw from Chang'an! ”

Cao Liu's army was walking side by side and entering Chang'an City together, and at this time, a small half of the army had entered Chang'an. After Liu Bei heard the order from Cao Cao's army, he was stunned at first, but before he could take action, more than a dozen soldiers suddenly rushed out from the two armies, scattered, and each took out a long strip of things in his hands, and with a light blow, the things in his hands burned, and a fire appeared. Then these people came to the sides of the cave, quickly found the lead hidden under the horse manure, and set it on fire without hesitation.

"Boom!"

Before Cao Liu could react, a fire quickly broke out in the city cave and spread from the middle. At the same time that countless soldiers were engulfed in an instant, the entire army was quickly divided, and Cao Cao and Liu Bei had to lead their troops to escape from the city where the fire spread, and more than 30,000 troops fell directly into the city.

At the same time, with the flames in the city cave, a fire quickly ignited in Chang'an City, including all around, and the entire Chang'an was quickly enveloped by the fire.

"Damn! Careless! Xi Zhicai said regretfully.

I thought that with the importance of Chang'an, Yuan Shu should not be so ruthless. After all, Yuan Shu is not Dong Zhuo back then, with his strength, as long as he temporarily gains a firm foothold in Xiliang, Chang'an is basically within his fingers. The 300,000 armor soldiers are not blown, but now they are just restricted by Shu Dao, and there is no need to burn Chang'an.

Moreover, Chang'an is full of eyes from them and the Guanzhong family, and if Li Dao and Guo Yan take action, they will definitely be aware of it. The combination of the two made Xi Zhicai selectively ignore the possibility of Yuan Shu burning Chang'an. After all, who would have thought that there was an old fox who had memorized this day more than a year ago, and had been secretly arranging it.

Secretly transported a large number of specially made fire oil with a very light taste to Chang'an, and spent a lot of time quietly scattered in various key places, and prepared the dead soldiers to infiltrate Cao's army in advance, this project is huge, even with the manpower and resources in Jia Xu's hands, it is enough to prepare for half a year, in order to give Cao Cao and Liu Bei a big gift.

For this reason, Jia Xu has made many deductions, and has calculated what to do if he is discovered. Fortunately, although Xi Zhicai discovered Jia Xu's trap, it was a little late, the 30,000 army was still a trivial matter, and the most important thing was that Cao Liu was trapped in the sea of fire.

"Damn!"

Xiahou Yuan and Guan Yu, who rushed to meet Liu Bei, kept brandishing their weapons to extinguish the surrounding fires to rescue the soldiers trapped in the fire. However, these fires are fueled by kerosene and are on a large scale, not ordinary fires lit by firewood from haystacks, which ignite at the touch of a button. The two kept extinguishing the fires around them, but often just after they were extinguished, the fires rekindled.

The situation was urgent, and in the face of endless flames, Cao Liu couldn't break out of the city wall at all, so he had to join Guan Yu and Xiahou Yuan first.

"Brother Mengde, what should I do now?" Liu Bei said anxiously. The flames around them were completely inexhaustible, and their 30,000 army and 20,000 cavalry were completely caught in the flames, unable to move.

In the face of the monstrous fire, Cao Cao had no idea, who would have thought that in just a moment, the entire Chang'an would fall into a sea of fire! Cao Cao just wanted to scold: Don't you want money for your oil?

The fire oil that can burn all over Chang'an, how much does this need! This is obviously not something that can be arranged in a short period of time, is he not afraid that he will accidentally miss it for a while, and the entire Chang'an will be destroyed?

Yuan Shu can only smile at this, Lao Tzu is rich, but he has a lot of oil, and he doesn't accept you to bite me!

In the land of fish and rice in Jiangdong, fish oil is not worth anything at all. In water warfare, playing with fire is the most common method, and Yuan Shu brought inspiration to Jia Xu by carrying forward his skills a little, and arranged such a monstrous fire.

The Jiangdong Navy has played a lot of tricks in playing with fire, arson and fire control are all pieces of cake, these fire oils are usually blocked, even if they are lit, they can only burn a house, and when they move a little in wartime, these will be connected again.

Although I didn't know what the hell Jia Xu was doing, out of trust in him, Yuan Shu was not stingy with the manpower of materials such as fire oil, and as a result, Jia Xu, an old fox who took one step and saw three steps, directly did things and completely arranged Chang'an into a huge crematorium, and there was no way out at all.

Now, due to the vigilance of Xi Zhicai, only 30,000 people are trapped in the city, and it is near the city gate, which is already very lucky. If the entire army is stationed in Chang'an, and a fire burns at night while most of the soldiers are asleep, absolutely no one will survive, and Cao Liu will be finished, and then the fun will be great.

"Zhicai!" Cao Cao turned to his own think tank.

Xi Zhicai's forehead was sweating, and now it seems that he has fallen into a desperate situation, these 30,000 troops can't be saved, and how to let the lord and himself and others escape is the first thing. But is Jia Xu's nirvana so easy to break? Looking at the city cave that was completely shrouded in flames, Xi Zhicai felt bitter in his heart.

Suddenly, the corner of Xi Zhicai's eyes swept over Guan Yu behind Liu Bei, his eyes lit up, and he said eagerly: "General Guan, how are you doing now?" How long does it last if you keep swinging? ”
