In front of the carriage, he noticed something strange again, the carriage was unguarded outside, and there was only one carriage, which looked very old.

In addition, the door of the carriage seems to have been freshly soldered, and it does not look like a simple solder, but all the gaps are soldered.

Yan Hao raised his hand and touched the mark of the solder, and found that the solder still had residual temperature, which was obviously just soldered.

Looking around, there were no normal locks or anything like that in this carriage, it was extremely weird, Yan Hao couldn't help but gasp, and said in his heart: Which one is this staged again!

Yan Hao gently tapped the shell of the carriage with his fist, intending to test whether there was anyone in the carriage, but even if there were people in the carriage and the welding was so tight, it was estimated that he would have been suffocated to death.

After knocking a few times, there was still no sound in the carriage, Yan Hao couldn't help cursing in his heart, the person in this kitchen knife door was so bad, he tied the person in the carriage and sealed it again, it was just heartbreaking.

But the words in the gray-clothed man's mouth must be true, and Yan Hao was sure in his heart that this Song Ya and Sister-in-law Liu must be near the carriage.

Also, the person who welded the door could not be Zhen Shijian, who had just lost to him! In his opinion, there was someone else.

In this dangerous situation, Yan Hao didn't have time to think about it at all, he immediately took out the Qilin Blood Blade, used all his strength, and slashed towards the wagon of the carriage with all his strength, tearing out a long and narrow opening in an instant.

The sunlight shone into the carriage along this opening, illuminating the dark carriage instantly.

After observation, the inside of this carriage is about five square meters large, and there seems to be a palm-sized "gold" engraved on the inner wall of the carriage, but there is not even a figure found in it.

Yan Hao said in his heart: Could it be that I was deceived by the men in gray, they are not here at all, so where will they be hidden?

At this time, Yan Hao felt a sense of anger in his heart.

"Bang!"

A big kick hit the door of the carriage hard, this kick was so powerful that it kicked the door down completely, Yan Hao walked into the carriage curiously, and kicked a few more times in it without suppressing his emotions.

But at this time, he noticed that something was suddenly wrong, and when Yan Hao stomped hard and stepped on the bottom of the carriage, there was a hollow sound, which attracted Yan Hao's attention.

Yan Hao leaned down, put his ears on the bottom of the carriage, and tapped a few times with his fingers, and found that the echo was hollow and narrow, which showed that there was indeed something under his feet, and there was a secret passage.

If Yan Hao is not mistaken, the iron plate of the carriage under his feet is as thick as an inch, and it is not as fragile and easy to cut as the wagon.

Even if you use the blood blade, it will be half the effort, in fact, Yan Hao only needs to go back and catch Zhen Shijian and the other three back, and take him to find Song Ya and Sister-in-law Liu, but in order to save people, Yan Hao didn't do that.

Yan Hao calmed down, carefully condensed the inner walls around the car, and found that there were no bulges, let alone any mechanisms.

Could it be the word "gold"?

Yan Hao was shocked in his heart, this kitchen knife door is really not ordinary, ordinary people can't see through this kind of mechanism at all.

In the West, the place where the broken mechanism is in the West.

This carriage is also coincidental, the place where it is placed is impartial, the four sides correspond to the southeast and northwest, and the place where the door is broken has to be found from the west wall of the carriage.

Yan Hao turned on the lighter and looked for it carefully, and sure enough, he found a golden word the size of a finger belly on the west side of the car wall.

"Boom!"

The iron plate at the bottom of the carriage actually moved, and the dust flew instantly, and the iron plate slowly shrank from the doorway to the back of the carriage, revealing layers of cement steps.

Looking inside, it was pitch black, very weird, and there was a sense of suffocation.

Yan Hao was not afraid in the face of the darkness, not to mention that he was saving people at this time, he held a lighter, lit the fire, and walked down, but before he could take a few steps down, he found that something was wrong.

The reason was that Yan Hao found that after walking down the steps for about ten meters, the lighter in his hand suddenly went out, and a trace of light disappeared in an instant, but this kind of thing is not as simple as it seems on the surface.

"Is this full of suffocating carbon dioxide?"

Yan Hao secretly speculated in his heart, people with common sense know that this carbon dioxide is colorless and odorless, but its density is greater than that of air, which is the most common in this kind of tunnel, but if there is really carbon dioxide in the secret tunnel, how can Zhen Shijian be okay after entering.

didn't have time to think about it, Yan Hao immediately retreated to the door of the carriage, in order to save Song Ya and Sister-in-law Liu, he could only fight, immediately adjusted the internal absorption, exhaled the maneuver, held a big breath outside the carriage, quickly turned on the mobile phone searchlight and walked down the dark road.

Not long after entering the dark passage, Yan Hao arrived at the bottom of the dark passage more than ten meters away, and found that there were torn clothes on the ground, which looked like Song Ya's.

But there was no trace of anyone, Yan Hao then walked forward and found that after passing a space of about two meters at the bottom, the stairs began to extend upwards again.

After Yan Hao walked up a few steps, he suddenly heard a strange sound not far ahead.

"Hmm!"

A familiar moan came from the front of the dark passage, and Yan Hao heard it and quickened his pace and ran over.

"Song Ya, are you still alive? there is carbon dioxide here, we have to hurry, we will be poisoned." ”

Yan Hao was happy when he saw that Song Ya was safe and sound, so he let out the breath he was holding in his mouth, but he reacted again in a moment, he quickly took off the black cloth that was blocked in Song Ya's mouth, and said anxiously.

"Brother Hao, you came to save me, I knew that you would definitely come to save me. ”

Song Ya's tears poured out like a spring, and she couldn't suppress it.

"Hey, Song Ya don't cry, it's okay, don't you feel breathing hard now?"

Yan Hao held his breath and didn't dare to breathe, his face was already flushed.

"I don't think so, Brother Hao, why do you ask that? Your face looks like a monkey's ass. ”

Song Ya's moist pretty face quickly overflowed with a girlish smile, and she couldn't help but ask.

Yan Hao embarrassedly took out a lighter from his pocket and slammed the flint a few times, and a flame suddenly ignited.

The faint firelight illuminated the figures of the two, and the shadows reflected on the wall were slightly warm, and the presence of this big brother who protected herself made Song Ya's heart no longer feel afraid.

"Yo he! This secret road is high-end! I see. ”

Yan Hao scratched his head, and couldn't help but smile secretly, the secret is that this secret path is U-shaped, and there are many mysteries in it, and those who understand the truth will naturally understand it.

Yan Hao said in his heart: There must be a vent not far from here, which means that there is still a door here to walk out.

However, at this time, Yan Hao didn't want to waste time and take risks.

"Save my mother! she's over there. ”

After Song Ya was loosened by Yan Hao, she stretched out her slender jade and pointed to the wooden stake leaning against the wall of the dark passage, and said anxiously.
