Suddenly, there was a muffled sound in front of the tunnel, as if An Shaoling had fallen to the ground, but fortunately, when Cang Ninghao was responding to the emergency, his hands were tightly clinging to the tunnel wall, so that he did not fall out, but Si Yunshang hit his back hard.

"Are you alright?" Cang Ninghao stabilized his body, turned his head, and asked with concern.

Si Yunshang shook his head and motioned for him to go down. However, the two of them just jumped to the ground, but they didn't want to be shocked by the situation in front of them!

She really heard it right, and sure enough, it was the sound of casting weapons, because, at this time, they landed in a cave more than ten meters above the ground level, looking down, the huge room was full of iron-making furnaces, and many craftsmen with bare arms and bare chests crushed iron ore and coal, and kept adding from the top of the iron-making blast furnace.

Some pulled air guns, while others clamped out the red-hot iron with inlays, and kept pounding and beating. Si Yunshang saw at a glance that there were no less than two hundred people here, as if it was a secret place for specially trained and organized weapons training.

A strong stream of heat came out of the furnace, and the temperature in the room was so high that they only stood at the mouth of the cave for a moment, and they were sweating profusely.

"Yunshang, in order not to be discovered by them, we can only follow here and climb to the opposite side!" Cang Ninghao said in a low voice, and at the same time pointed to the big stone raised on the opposite side, behind the big stone, there was a secret passage exit.

But to get to the opposite side, he could only climb over with his body completely attached to the wall, which said to Si Yunsheng, it was a piece of cake, but for An Shaoling, who didn't know martial arts and was a little timid, it was as difficult as climbing to the sky, he looked at Cang Ninghao glutinously: "Palace... Your Highness, I'm afraid Shaoling won't be able to get by......"

Cang Ninghao glared at him coldly: "If you don't want to bury yourself here, just crawl over for me!" ”

With this low voice, An Shaoling stood aside complacently, not daring to squeak. And Si Yunsheng, who had already prepared, wiped his hands on the ground, stained them with dust to sweat, and then firmly grasped the stone wall, carefully stepped on the bulge on the wall with both feet, pressed his body against the wall, and walked towards the opposite side step by step.

This time, Cang Ninghao didn't let An Shaoling break off, for fear that he would have another limb, so he forced him to follow Si Yunsheng's example, and climbed the wall and slowly crawled to the opposite side.

An Shaoling's beating heart hung in his throat, large beads of sweat ran down his forehead, slid across his cheeks, and along his neck, sliding into his clothes, he held his breath and condensed, not daring to look down at all, but suddenly, his left foot slipped and slid down!

Si Yunshang and Cang Ninghao freed up one hand at the same time, one covered his mouth that was about to scream, and the other twisted his body that fell down!

The three of them all sweated, but fortunately it was just a false alarm, and finally reached the opposite side smoothly. As soon as he landed on the ground, An Shaoling's entire body collapsed to the ground, and he looked at the blazing stove below with lingering apprehensions.

Walking into the secret passage, Cang Ninghao took out a brocade puff from his arms and handed it to Si Yunsheng: "Wipe your sweat!" ”

Si Yunshang's cold face was crimson, not because he was shy, but because he was too hot. She was not polite, and went straight to Jinpa, wiping her sweat while continuing to walk forward.

But before he could take a few steps, there was a loud sound on the side, as if there were many people practicing! Si Yunshang didn't have any doubts, and quickened his pace, until he reached the end of this secret passage, and the shock in his heart far exceeded the fire refining furnace he had just seen!

I saw that under the secret passage, there was a larger secret room, and there were thousands of soldiers training in it! Judging from their skin color, it is obvious that they have not seen the sun for a long time, and looking at the speed and strength of their knife slashing, they should have been trained for a long time to have such skills.

Many doubts surged into my mind at this moment at the same time, who would be refining weapons under the ground of this palace?

Will it be Han Zeyu?

No, it can't be him!

Si Yunshang immediately denied this idea, because everyone in the world knew that King Shun only trained in the Divine Battalion, and his ironclad soldiers were already the strongest army in the world, so there was no need for him to train here anymore!

So, who will it be?

Si Yunsheng twisted his eyebrows, and suddenly thought that he saw the military books he read in the emperor's bedroom that day, and at that time, An Shaoling also took those military books away as treasures and didn't let her read them. At that time, she was suspicious that the emperor wanted to take back the military power from Han Zeyu's hands.

Now I unexpectedly saw everything in the secret room, so the weapons and soldiers here may have been secretly trained by the emperor?

"Cang Ninghao, who do you guess is secretly training weapons here?" Si Yunshang asked casually, in terms of the art of war and strategy, she is not as good as Cang Ninghao, who was born in the royal family and has read military books since she was a child, so she wants to hear his opinion.

Cang Ninghao's purple eyes were thoughtful, and he said after a long time: "It won't be King Shun, but it may not be the emperor!" ”

"What do you mean by that?"

"The entire Longrui Kingdom knows that the emperor has no intention of politics, so it is unlikely that he will secretly refine weapons here!" Cang Ninghao said, and at the same time he was thinking about it, thinking about who might be training here.

But at this moment, An Shaoling, who was supposed to stay quietly on the side, accidentally stepped on a few gravels, and in an instant, those small stones fell over, and such a slight sound alarmed the thousands of soldiers who were training!

"Tell me, someone's breaking in!" Suddenly, I don't know who shouted!

"Quick, catch them, we can't let them get out alive!"

All of a sudden, all the soldiers grabbed their weapons, scattered from all directions, and ran into the secret passage, about to rush up and catch them!

"Hurry up, they are outnumbered, and they are familiar with the terrain here, we have no way but to return from the tunnel we just fell down!" Si Yunshang made a quick decision, went back the same way, climbed to the entrance of the tunnel at the cave as fast as possible, and waited for Cang Ninghao and An Shaoling to also climb over, then jumped into the tunnel and climbed up with difficulty.

Even in the tunnel, he could still faintly hear the shouts of those soldiers, Si Yunshang was secretly annoyed, this time I am afraid that there will be more evil and less luck, and the palace is really not so easy to escape!

The slope-shaped tunnel is easy to roll down, but it is extremely difficult to climb up, but they finally climbed out, but they don't want to be blocked by soldiers rushing up in front and back! However, fortunately, there are not many people coming, they are obviously scattered and blocked the various intersections, if they are concentrated together, I am afraid that with the three of them, they will be powerless!

Si Yunshang didn't hesitate for a moment, pulled out the dagger tied to his thigh, and went straight up, his slender legs were raised suddenly, kicking left and hooking right, and the dagger in his hand was like a sensitive poisonous snake, hitting the abdomen of the two soldiers directly, and each of them slashed hard!
