Zhao Donglai took out the lighter he was smoking and lit a relatively dry firewood to illuminate the entire long tunnel.

This should be an artificially dug hole, Zhao Donglai took a look, it was estimated that there was a gate in front of him before, but for some reason, it may be that the mudslide covered the gate, and the opening he jumped down just now is a skylight, it is estimated that the glass is old and broken and cannot withstand people stepping on it.

Zhao Donglai didn't rush inside, but turned around and looked at the blocked door, he touched it, it is modern technology, although there are some years, but the heavy steel of the gate is obviously not something left over from history, more like the kind of explosion-proof door in the former military industrial base.

It is certain that the cave was built in modern times, and Zhao Donglai then turned around and went deeper into the tunnel.

Walking and walking, fortunately he had the ability to predict, and the next second he sensed the picture of himself stepping on a certain mechanism and flying out poisonous arrows from both sides.

Although his body can't be injured by arrows, this poisoned arrow can penetrate deep into the pores through the surface of the skin and make your whole body uncomfortable, scratch when you try to tickle, and then the venom will poison you to death through the blood!

For this reason, after Zhao Donglai stopped, he deliberately stretched out his foot and stepped on the place, and then quickly withdrew.

In the next second, the poisonous arrows brushed in the cracks of the two rows of walls were sharp and flashing.

Zhao Donglai is very strange, it stands to reason that the mechanism must have a similar touch of a button device when stepped on, but this is completely a concrete floor without any recessed device, how is this mechanism set up?

If it was a sensor device, then he would consider the year the cave was built.

Fortunately, he has the ability to predict, otherwise anyone would have given his life here a long time ago.

Zhao Donglai squatted down and picked up the arrow and sniffed the venom on the arrow, he frowned.

He knows this poison, Master will match, and so will he.

Zhao Donglai raised his head and looked at the long tunnel, and became more and more sure that this cave might have something to do with the master.

He continued to walk inside, walked a long way, and before long, he saw several corpses!

The skeleton frame is large and long, indicating that the corpses were tall when they were alive.

After Zhao Donglai squatted down, he casually touched the dusty cloth and found a line of English characters written on their cuffs.

Employee uniforms for an engineering company.

Probably a foreign engineering team. Zhao Donglai thought that the underground project was probably from them, and Zhao Dong took a look, and there were obvious traces of rubbing on the throat bones of these people.

Someone must have choked off their necks and killed here.

Could it be Master?

If he asked these people to build this underground cavern, why kill them? Didn't he want this place to be known? What's here?

Zhao Donglai raised his head and looked around, there was no way out.

There was only one wall to the place where the corpses were piled up, and there didn't seem to be anything from the time I came in.

Zhao Donglai pondered, there was nothing, why did he spend energy to make this cave?

And why do you kill?

Immediately, Zhao Donglai stood up and looked on the surrounding walls to see if there were any mechanisms or secret doors or the like, the surroundings were very spacious, and the lights were very dim, if you wanted to find it carefully, you had to look carefully and slowly.

And you have to get close to the lights and look for them.

After searching for a long time, he found a recessed pattern in the lower right corner of the wall.

Because of the time of sealing the dust for too long, the recessed groove has been covered with sand and dust, Zhao Donglai buckled the dust with his fingers, blew it, and then completely saw this pattern.

Similar to the pattern of a certain shield, Zhao Donglai reached out and touched it, but there was no mechanism of the sensing device, he knocked and pushed hard, but there was no reaction, it seemed to be an ordinary answer.

Zhao Donglai looked at this wall, he was sure that the structure of this wall was not purely a stone wall, and the heaviness was definitely like other steel wall sandwich walls.

There is definitely a mechanism here that leads to the secret door, and Zhao Donglai is sure that this pattern is the key, but he suddenly said that he was helpless about how to activate this mechanism.

He got up and went back to the corpses, and swept his feet to see if there was anything critical on them.

Disappointedly, the bones were lined with nothing but rusty flashlights and corroded batteries, and things like their leather belts.

Zhao Dong paced back and forth and continued to find the key things, and his mind was also spinning.

First of all, it's certain that this cave has something to do with Master, because the venom on those arrows is something he developed. So I'm sure that this place must have been made by the master, and since he made this place, then the method of opening this mechanism must have something to do with him.

He even killed these engineers because he didn't want outsiders to know about it, and there must be something important to him, right?

Since it's very important, he will definitely carry the key here, otherwise he won't be able to open it if he loses it?

Zhao Donglai thought about it, and instantly opened a pair of eyebrows.

Then he subconsciously put his hand into his trouser bag and took out the thing that the master had passed down to him - the Divine Barracks Token!

Zhao Donglai lowered his head and looked!

Isn't that what the shield looks like?

Zhao Donglai's pupils dilated, and he hurriedly walked to the corner, squatted down, raised the torch, and compared the dimensions of the two.

I was surprised to find that the recessed part of the pattern was just enough to put the Divine Barracks token in.

He breathed a little heavily, and then when he reached out and put the token inside, he stared for a moment to see if something would happen in the next second.

Simply, the wall in the picture has really been removed!

After Zhao Donglai opened his eyes, without further ado, he quickly stuffed the token into the recessed pattern, and then slapped it in.

In the next second, a rumbling sound came from the ground, and there was some shaking, and the huge thick wall slowly rose upward.

It may be because it has been useless for many years, and it is a little stuck, but in the end, there is an opening, Zhao Donglai saw that it was pitch black inside, turned around and went to burn the clothes of those corpses and threw them into the dark space inside the division gate.

Under the shaking of the firelight, Zhao Donglai could capture that it was a large flat space inside, with many cabinets and instruments with modern equipment.

After making sure that there was no danger, Zhao Donglai was afraid that he would not be able to come out if he went in, so after casually pulling out the token, he hurriedly rolled his body and got into it while the stone gate did not fall.

After the stone gate rumbled shut, the wind outside blew his torch almost extinguished, Zhao Donglai hurriedly protected the fire, but the next moment, the lights suddenly turned on here, and the lights were lit up all around, and it was white.
