When the hour came, the night was like a curtain.

Su Xiaochen stood outside the Baitai Gate of the Wanhua Imperial Capital, and looked up at the towering Zhangren Palace.

The palace, which has always been brightly lit, looks dull, as if it has long lost the vitality of the royal family, like a pile of decayed pavilions, just waiting to decay into the earth.

Bataimen ...... Su Xiaochen remembered that he had ridden horses to the outskirts countless times, always going out of the city from here, and only coming back late when it was late, and Uncle Kang was always waiting at the gate of this city with an anxious face......

I didn't expect that the nameless boy who rode horses in the past would stand in front of this behemoth-like imperial capital today, and he wanted to take it into his hands!

The dragon scale army has long been lost at the gate of the city, replaced by Xu Fu's soldiers, and the people in the city have fled one after another under the moonlight.

Xu Fu once asked Su Xiaochen worriedly, what if there were some dignitaries disguised as ordinary people like Pei Ran?

"Let them go, our goal is to take the imperial capital."

"But what if Ye Zhiqiu and Zheng Lun are also mixed in?"

"He won't." Su Xiaochen's tone was so firm that it could not be refuted.

Xu Fu thought about it, could it be that Su Xiaochen wanted to let his uncle go when he remembered his old feelings, but he felt that his words were unfounded, and he didn't want to pierce this layer of window paper, so he didn't squeak anymore.

Su Xiaochen knew that he didn't believe it, and he didn't bother to explain more to him.

Uncle knew that since he had come to this point, he would not look back. In fact, he has always judged very accurately in the whole game, but he did not estimate that he would not be able to wait for the day when Wen Lan crossed the river, in fact, he could wait for the Cangwu army and the Imuran army to completely start a war before making a move, but he was afraid that Wen Lan would use this as an excuse to determine that he would reap the benefits......

After all, the only people he can rely on are the Imurans, and as long as the Imurans refuse to help, the Songyang Kingdom will always be an illusory bubble. So in front of Wen Lan, he had almost no room for bargaining. At this point, Su Xiaochen was very pitiful and even a little sympathetic to his uncle's humility.

However, there was one point, my uncle still misjudged.

He thought that he had been dormant for decades, and Emperor Wanhua was his home field, but he forgot that Wanhua was built by the Mu Yun clan, and it was the home of the Mu Yun clan.

And Mu Yunyou taught everything to Su Xiaochen.

The military books, secret passages, maps, and various secrets in the army, Mu Yunyou taught them all.

Mu Yunyou firmly believes that this teenager is worthy of trust.

Su Xiaochen put his hands behind his back and clenched a letter tightly in his sleeves.

That was when he left the Kuntou ship and planned to go to Emperor Wen's camp to borrow troops, and Zhu Yuxiao, the princess of Yinquan, gave it to him personally.

"This was handed to me by Taishi Zuo, and I saw that it was your name written on it, so I sent it to you."

Su Xiaochen was very surprised, he thought that Taishi Zuo had no sense, but he didn't expect to be able to write a letter. I didn't expect that I would let Zhu Yuxiao hand it over to me.

There is not a single word in the letter, just a few landscape paintings.

But Su Xiaochen could recognize at a glance that the painting was Miaodai Mountain behind Zhangren Palace.

Although the painting is simple, the style is very similar to the drawings in the "Yun Ce".

Only those who are familiar with Muyun's art of war can understand the meaning of the painting.

Unexpectedly, Zuo Taishi ......

Su Xiaochen once again appreciated the terrifying nature of Mu Yun's calculations.

According to Mu Yun's idea, Emperor Wanhua must be difficult to attack.

However, in case the enemy launches an offensive from the inside out, such as locking the palace gate after the palace coup, then all the defensive points designed by the Mu Yun clan for the Wanhua Imperial Capital will in turn become the enemy's advantage. So you have to take a precaution just in case.

This is the secret buried by the Mu Yun clan, and it is also the secret of the Wanhua Imperial Capital.

Ye Zhiqiu, who thought he occupied the home field, actually stood on top of the Mu Yun clan's home field from the beginning......

Su Xiaochen looked at the rising moon and asked, "What time is it?" ”

"The hour of the child has passed."

"Eagletail...... It's time to get your hands dirty. Su Xiaochen muttered to himself.

Before the words fell, some sporadic fires suddenly appeared on the sides of the beacon towers in the city in the distance.

The flames spread upwards rapidly, sending the flames into the immensely solid palace walls, and soon, the vicinity of the Zhangren Palace, the highest point, began to be surrounded by firelight, and countless towering ancient trees were ignited, becoming firewood in the raging fire.

Xu Fu looked at the city in amazement, he didn't know how this could light a fire. You must know that there are thousands of ambergris at the foot of the palace wall, how can this fire be ignited in an instant and only burn around the palace wall, but it does not endanger the periphery of the city where the people below are located.

Many of the people who had escaped the city also stopped to watch, and the more they looked, the more they secretly rejoiced, otherwise they would have lost their lives if they stayed in the city.

Su Xiaochen was watching the fire gradually rise, and suddenly a cry came from behind him: "Brother, how can you do this, your father and mother are still in the city, do you want to burn them to death?" ”

"Sister Yin!" Su Xiaochen took her into his arms and protected her, and said softly: "Don't worry, I have handed over my aunt's affairs to Vulture Tail, and she will definitely be able to rescue my aunt." And the fire will only burn near the palace wall of the palace, my aunt is in Qinghuai Villa, there is still some distance, you don't have to worry too much. ”

"Really?" Ye Yin was suspicious, she knew that her brother never lied to her, and she was slightly relieved at the moment.

Xu Fu couldn't help but ask: "Master Su, I looked at it for a while, and I felt that this fire was a little strange, from a distance, it seemed to be a vein gathering together, and the place it passed was like a waterway through the mouth of a dragon's saliva, but even if there is no water in the waterway, there is ice, how can it burn?" And why did the fire only go up, but not downwards at all? ”

Su Xiaochen pointed to the Miaodai Mountain at a high place: "The ambergris mouth divides the water of the waterfall, and the further down you go, the more the ambergris mouth has, so does General Xu know that the more you go up to the source, is there anything there?" ”

"I don't know ......"

"There's a cave there, and in the middle of it is a pool of water formed by the waterfall draining. If it was freezing today, the pool would have been frozen. ”

Xu Fu obviously didn't understand what the connection between this pool and the fire was.

"The successive generations of Mu Yun Taishi felt that Emperor Wanhua was impregnable, but in order to prevent them from accidentally falling into the hands of the enemy, they still thought of a strategy. They lay two hundred barrels of oil in the cave. ”

"Kerose?!"

"Yes, if you want to capture the Wanhua Imperial Capital, you must wait until the day of the ice. Just like now! I have ordered Washioo and the rest of the ten Ryuxia masters to sneak into the cave before night and dump all two hundred barrels of fire oil on the surface of the pool. The surface of the pond is high, and the oil will be dispersed to various places along the walls of the imperial palace like the water of a waterfall. Because the waterway is frozen, a film of oil is applied to the ice where the oil flows. When it's time to get there, just light a little fire at any of the ambergris mouths under the wall......"

Su Xiaochen stretched out his hand and made an explosive gesture.

Xu Fu was stupid when he heard it......

"But won't the ice melt after the fire?"

"Yes, but the ice doesn't melt that fast, the oil is flammable, and when it is ignited, it will immediately spread upwards along the waterway, and before the ice melts, the fire will be sent to all corners of the palace. After that, it's too late to wait for the ice to melt......"

"Why?"

"The siege of a city must be strong, and in order to be strong, it is necessary to add firewood. The countless towering trees near the palace were deliberately planted by Master Mu Yun back then, in order to replace the fire oil that was about to burn out at this moment and keep the fire going. ”

"But why did the fire only burn the palace and not the bottom? Could it be that Master Su can still control this fire as much as he wants? ”

"Yes, it's just not me, it's the wisdom of Master Muyun. General Xu, have you ever wondered why this oil is two hundred barrels, not one hundred barrels or three hundred barrels? ”

Xu Fu suddenly realized: "It turns out that the number of these two hundred barrels has been carefully calculated by Master Mu Yun!" ”

"Exactly, two hundred barrels of fire oil are just enough to flow inside and outside the palace walls, and there will be no more below. Therefore, the fire only burns upwards and does not affect the people under the city. It's just that this fire finally cost the lives of more than 20,000 people of the Dragon Scale Army, and they are also people with wives and children, although it is a helpless move, it is also a heavy sin. Presumably, when Master Muyun was in this position, he could only focus on the overall situation, and he couldn't take into account the life and death of these soldiers. ”

"Then Ye Zhiqiu and Zheng Lun will also be burned to death?"

"About ...... No. ”

"Why is that?"

"Qinghuai Villa is a little far away, although it will also be affected, but it will not be impossible to escape from their lives, but the palace wall has become a wall of fire, they can only escape from the villa, but they can't escape from the wall, and when the fire is extinguished, we will go up to contain the prisoners, it will be easy. So as long as they don't enter the Zhangren Palace, they won't die. ”

Ye Yin was frightened when she heard this, and she couldn't help but get anxious when she looked left and right and couldn't see the figure of the eagle tail.

"Brother, why is there no one in sight of Vulture Tail? Will my mother really be okay? ”

"I'm sure Eagletail has what it takes."

"Why do you believe in her so much?" Ye Yin always felt a sense of conformity to the eagle tail, first Cao Xiwen, and now her brother, why did every man look at her with such appreciation?

"Because when I was in Luoxia Bay, the capital of Taiye Kingdom, I have seen her skills and courage, even among the ten thousand people, there is no fear, so far I have never made any mistakes in the affairs that Qiu Yuejun explained to her. So I'm sure she'll bring her aunt back as well. ”

"Why is it just my mother coming back? Where's Daddy? Ye Yin suddenly heard another meaning from Su Xiaochen's words. She couldn't help crying: "Are you still hating your father?" Don't want to save him? ”

"It's not!" Su Xiaochen hugged Ye Yin's shoulder and said loudly: "It's not that I don't want to save him, I want to see him more than you, I want to ask him in person, has he ever treated me as a ......"

Halfway through his words, Su Xiaochen suddenly choked up, and it was difficult to continue.

He waved his hand and said, "Sister Yin, it's not that I don't want to save him, it's just that I'm not sure." You don't know a lot of things about your uncle, so you won't know how deep his obsession is, I'm just afraid that he is gone, maybe he is unwilling to flee for his life. ”

Ye Yin was already sitting on the ground and crying silently.

Dad seems to be gentle and elegant, but in fact he is as ruthless as iron, this ruthless word is by no means only for others, especially for himself. Sometimes Ye Yin even wonders, her father is a dignified person, why he always lives a light life like water, although it is not to say that he is poor, but there is no luxury, the food and clothing at home is only average, and he is also blindly forbearing.

Forbearance and ruthlessness are just a piece of paper.

If a man is cruel to himself, what is there to fear?
