Every once in a while, General Chu and the others could hear the faint sound of stone wall knocking, but some of them were not really heard, and they were faintly visible.

Following the sound, the soldiers smashed several small holes, but they did not see any human figure, so they had to enlarge the holes and send people down to find them.

Two days later, after the loss of several more groups of probes, some useful news finally came back.

"General Chu, this secret passage has two layers, and the emperor is probably in the lower layer!"

General Chu felt sorry for his soldiers, but he was angry, so he simply threw the hammer head down and shouted:

"Smash, smash this secret passage to a pulp!"

He'd only seen two floors, but he hadn't heard of the two-story underground passage. This Northern Barbarian royal family is really good, the three holes of the cunning rabbit!

In order to save his life, he really spared no effort, no wonder the Northern Barbarians lacked everything, it turned out that they were used by the Northern Barbarian royal family on crooked ways!

General Chu was so angry that he crossed his waist, so he listened to the guards:

"General Chu, the guards of Wu Xi beside the queen mother are here, saying that there is something important to discuss with you."

When General Chu heard this, he chuckled in his heart.

Could it be that something happened to Chu Yunxi in the palace of Yunxiao Kingdom?

"Let him in."

General Chu nervously watched Wu Xi approach and spoke first.

"Wu Xi's guards, the queen's mother, the little prince, and the little princess, are you okay?"

Wu Xi did not answer directly, but said:

"General Chu, take a step to speak."

His words scared General Chu a lot, it seems that something big is really happening, otherwise why avoid others.

He quickly held his back and left.

"Speak quickly!"

Wu Shu turned sideways and let out the somewhat thin guards behind him.

The guard raised his hand and took off the hood from his head, revealing a face that amazed all beings.

Although it has the exhaustion of the wind and dust, it is even more lovable.

"Father!"

"Xi'er? You, you, why are you here? How did you come to the Northern Barbarians? What about the little prince and the little princess? ”

General Chu felt that his heart had really endured too much in the past few days. A wave has not settled, and another wave has risen.

Chu Yunxi didn't want to waste time and got straight to the point.

"Father, the children are fine, they are in the palace well, and someone is taking care of them. I have the drawings of the secret passage of the Beiban Palace, and I will go in and bring the emperor and my brother out. ”

"Xi'er, how did you know that the emperor and your eldest brother were trapped in the secret passage agency? How did you get the blueprints for the secret passages here? ”

General Chu's brain was a little insufficient.

A daughter's family came to this place of war alone. Xi'er's boldness, when did it become so big?

"Father, in the future, my daughter will slowly explain to you that it is important to save people first."

Chu Yunxi said, looked around, and went straight to a corner.

"Xi'er, where are you going? The entrance to the secret passage is over there. ”

The direction that General Chu pointed in was the opposite direction of Chu Yunxi.

Chu Yunxi did not stop.

"Father, you just have to pacify the three armies and wait for us to come out."

Chu Yunxi walked to an inconspicuous corner, touched the mouth of a half-human-tall stone lion, and turned a small ball three times.

General Chu looked straight, and a small door was revealed, there was actually a secret passage entrance here?

How did Xi'er know about this entrance? Yes, Xi'er said that she had a secret passage blueprint.

"Xi'er, Xi'er, you can't go in, it's very dangerous inside, you give me the drawings, and I'll send someone in to save people. Which of them is not better than you? ”

Chu Yunxi was blocked by General Chu and pointed to his head helplessly.

"Father, the drawings are all here, if you want to draw them, it will take several days, can the emperor and brother wait? Don't worry, I know in my heart that I won't come to this nonsense. ”

General Chu couldn't, so he had to retreat to the next best.

"The Father is with you!"

Chu Yunxi shook his head firmly.

"Father is not afraid, there is no one outside, and when we come out, will the sky change again? If my father is not at ease, send a few capable men to come with me. ”

Chu Yunxi was only afraid that he would meet the Northern Barbarian Emperor halfway and be plotted by him.

It was because of what Chu Yunxi said that General Chu had been in a hurry outside the secret passage.

When he was in a dilemma, Chu Yunxi had already stepped into the secret passage. Wu Xi and Si Qi followed.

"Come on, protect the queen!"

General Chu hurriedly beckoned his guards and went in to protect Chu Yunxi.

He was in a hurry. God willing, Bodhisattva blessing.

He has fought on the battlefield for many years, and he has always believed that my orders are in me, not heaven and earth. At this moment, I can't help but ask God to worship Buddha.

As long as the emperor and his children can come out safely, what if he believes in Buddhism in the future.

In the secret passage, Wu Shu took out a bag of charcoal he was carrying, and marked the stone wall as he walked.

Chu Yunxi mobilized the drawings in his mind while commanding:

"Take the door on the left! Turn right! The switch is under the belly of the stone toad, this section can't be stepped on, jump over! Straight ahead ......"

The soldiers who followed up, according to what Chu Yunxi pointed out, began to move forward cautiously and vigilantly.

The more I walked, the more I found that the road pointed by Chu Yunxi was not wrong at all, and the speed became faster and faster.

"Queen Mother, I've found the steps!"

Chu Yunxi took a deep breath, in this kind of dangerous underground secret passage, no one could be calm.

"Let's go down."

As long as she marks the right way, she believes that Jun Lingyun can always open the right door, walk on the right road, and find the exit.

Wu Xi seemed to hear something, put his ear to the stone wall, and listened carefully. Suddenly surprised:

"Queen Mother, someone is knocking on the stone wall."

Chu Yunxi hurriedly asked, "Which direction?" How far away? ”

Wu Xiying said:

"Right. As for how far, the subordinates can't say. ”

In this twisty and bizarre underground passage, it was really difficult for him to judge the distance.

Chu Yunxi closed his eyes, and a huge map of the secret passage appeared in his mind. Since she didn't know how far it was, she could only rely on the direction and slowly find it.

"Wu Xi, is there a code between you and the emperor? Can you tell the emperor to wait in place with the sound of percussion? ”

Wu Xi was a little embarrassed:

"Queen Mother, codes, are generally gestures, marks, etc., and rarely use the number of taps to convey the meaning."

Chu Yunxi locked his eyebrows and pondered for a while, and suddenly had an idea.

"War drums! "The Art of War" has clouds: the man who holds the flag with a golden drum, so the eyes and ears of a person are also.

The drumbeat of the war drums can command a large army. You hit the stone wall with the beat of a drumming that stops, or stays, or waits for help. ”

Chu Yunxi didn't know what it should be, but there should always be a meaning that was close.

Wu Xi's eyes lit up, the queen mother is very intelligent, and she is knowledgeable, and she even understands "The Art of War".

He immediately raised the sword in his hand and began to hit the stone wall hard, high or low, sharp or slow.
