Suddenly seeing a secret passage appearing under the entrance of the cave, Li Jing could no longer remain reserved. She immediately realized that the matter was of great importance and hurriedly retreated aside and called to the contactor in her ear:

"Yang Kai, Yang Kai...hello..."

Unexpectedly, she shouted a few times, but no response came from the contactor.

"The cave is too deep, there is no signal!" Li Jing looked at the cave under the light, turned around and rushed to another agent at the scene, "Ayong, let's do it, you go out to find Yang Kai now and call the headquarters to apply for support!"

"Okay!" Although the agent was still in surprise, he still followed Li Jing's command and ran out of the cave.

"Xiao Hang! Team Leader Zhao!" Then, Li Jing signaled with a pistol, which means that we can go down and catch people now!

Xiao Hang could not wait long ago, and after Li Jing signaled, he was the first to jump into the entrance of the cave.

Xiao Hang was quick to move and stepped on the concrete stone slab in a few seconds. At this moment, the internal combustion splitter that had been carried in before fell aside, and there was still a lot of dust at the entrance of the cave.

To be cautious, Xiao Hang lay down and first observed the secret passage at the bottom. After finding that there was no danger, he waved his hand to Zhao Yu and others.

Zhao Yu glanced at Cui Lizhu, and Cui Lizhu was also very excited and hurriedly nodded hard at Zhao Yu. So Zhao Yu also took the pistol and crawled along the edge of the cave with Cui Lizhu.

Immediately afterwards, Li Jing followed from the other side of the cave entrance.

Because the entrance of the cave was small, Xiao Hang jumped into the secret passage below without making any sound. When Zhao Yu saw Xiao Hang go down, he also reached out to grab the concrete and entered the secret passage.

As soon as he entered the secret passage, a cold and humid breath came to his face. Zhao Yu was worried that the air here would not circulate, so he immediately turned on an invisible detector that could detect air.

Just when the detector was detecting the air, Zhao Yu had already seen the general situation of the secret passage with the faint light coming from above. But the secret passage was 3 meters wide and about 2 meters high, and the walls and the ground were covered with cement, which was very similar to the air raid shelter. There were light bulbs from the War of Resistance Against Japan in the upper corner of the wall, and there were black wire connections between the bulbs.

Look at the ground again. There are grooves for drainage at the corners on both sides of the ground, and on the ground in the middle of the secret passage, there are tracks that are only found in the mine!

Although there are not many things you see when you see them, it is possible that this is a military fortress during the Anti-Station period!

Wow……

Zhao Yu was amazed in his heart, could this military fortress hidden in the mountain be the treasure-hiding place that the Secret Service has been looking for for more than 80 years?

Little Japan... It was so unexpected! Such a place was built near Yishan Fortress? It seems... Cui Lizhu might have guessed it right!

I tied a grandma bear... When I thought of this layer, Zhao Yu couldn't help but feel excited, and thought in his heart, could it be... Are the hundreds of tons of gold and priceless treasures hidden here?

This is...

During the observation, the detector reported the results, and there was no problem with the air quality in the secret passage.

However... although there was no problem with the air, Zhao Yu still noticed two things.

The first thing was that he looked at both sides of the secret passage, but did not see the traces of the two people before!

Logically speaking, the two of them didn't take long to get down. If they were lighting equipment, they shouldn't be able to see it. I wonder if the secret passage was not straight? The two of them had turned to another place?

But seeing that there are roads on both sides of the secret passage, I don’t know which direction they are heading?

In addition, Zhao Yu looked up and noticed the broken gap. It was just above the secret passage. Since the roof of the secret passage was made of concrete, the two people used internal combustion splitters to break the roof.

The location is so accurate, so what... the two of them must have detailed information about the fortress? How did the two of them get the information?

At this moment, Li Jing had already gone down to the concrete layer and was entering the secret passage through the gap. Seeing this, Xiao Hang quickly came forward and reached out to support Li Jing.

Why?

When he raised his eyes, Zhao Yu noticed that something seemed wrong with the gap that had broken through the concrete... Before... the kind of internal combustion splitter... If it were the gap that had just been split, could it be split so big?

Although Zhao Yu is not very familiar with this kind of professionalism in gravel, he feels that it seems unreasonable in terms of time!

Don't forget that they followed the two suspects in immediately. Can such a large gap be opened in just a few seconds with a splitter?

like……

Why?

Unexpectedly, just when Zhao Yu was confused, a strange noise suddenly came from above the entrance of the cave. The next second, he saw a black ball suddenly rolling down from the entrance of the cave!

ah?

It was a black ball the size of a palm, and there were many holes on the ball like a honeycomb...

Just as the black ball suddenly rolled down, Li Jing, Xiao Hang and Cui Lizhu were also surprised and completely unexpected.

If you want to react, Xiao Hang is the fastest. When he saw the black ball rolling down, he immediately shouted "No," and then quickly took Li Jing down and pressed Li Jing under him!

Although Zhao Yu's reaction was not slow, he still had no time to open props such as bulletproof vests and so could only turn around instinctively and fall to the ground...

puff……

As a result, when the black ball landed, many flying needles suddenly spurted out from the many holes! Since there were holes all over the sphere, the flying needles also spurted in all directions!

Twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist twist

The flying needles shot randomly. With such a large-scale ejaculation, Zhao Yu and the other four were inevitably shot by the flying needles.

Not only did Zhao Yu feel a pain in the back, but he even had a flying needle pricking his ear!

ah……

Zhao Yu felt pain and reached out to pull off the flying needle on his ear, and bleeding suddenly came out of his ear.

This needle...

Zhao Yu was about to see what the flying needle looked like? But the electric light above the hole suddenly went out, and the secret passage suddenly fell into the darkness!

Dada dada...

Unexpectedly, in the dark, two more things rolled down from the hole. When the things landed, Zhao Yu immediately smelled a pungent smell!

At this time, the detector in his mind suddenly came from information, with a lot of chemical symbols appearing on it, and a red alarm came!

Although I don’t know what those symbols are, Zhao Yu is very clear that those are definitely not good things! And... the flying needle that I shot just now must be... all...

I click!

As soon as Zhao Yu thought of this, he immediately felt dizzy, heavy eyelids, and drowsy...

not good!

Must be anesthetized!

At the critical moment, Zhao Yu hurriedly tried to get angry and used the invisible antidote and the invisible respirator together!

The system props were extremely powerful. After using the antidote, the anesthetic agent in his body was immediately resolved, and the drowsiness suddenly dissipated.

In order to see things clearly, he quickly used another invisible night vision device, and then he suddenly realized that the secret passage was covered with thick fog, which could undoubtedly cause a coma!

Cough cough... Cough cough...

Next to Zhao Yu, the coughs of Xiao Hang and Cui Lizhu were heard. Zhao Yu wanted to go over and help them, but suddenly heard a burst of rapid footsteps from right in front of him!
