The three people in the back followed closely, and such directness and simplicity would bring them a lot of time saving, and they went straight to the end of the field of vision they were currently exploring.

It seems that the information provided by the fox shows that the two hundred big men are still moving slowly, and the surveillance and shooting equipment they are carrying keeps transmitting all kinds of information.

Some of the passages at the end are presented directly on the navigation map to avoid dead ends.

With real-time monitoring and navigation deduction from high-tech computers, they avoided many forks in the road and entered a dead end.

Without this navigation, it would be absolutely difficult for them to enter the core, and they would even be trapped on the periphery, which is simply a labyrinth map passage.

There are many intersections, so you can't distinguish them at all, if Lin Zhen didn't have a tablet to instruct, I'm afraid he would have lost his way forward by now.

Wang Shi couldn't help but ask in the back: "Boss, we passed through more than twenty forks just now, is this road the nearest shortcut?" ”

He couldn't believe that in such a complex area, ordinary people who came in would definitely be unable to get out for the rest of their lives, either starving to death or dying of thirst.

Luckily, the passage is not stuffy, and the oxygen is sufficient, as if it is in harmony with the air outside.

There is a big difference with the temperature outside, and invisibly, this underground passage is like a very huge natural air conditioner, constantly filtering and cooling, but it does not consume the slightest oxygen and the right amount of carbon dioxide.

Half an hour later, it was very strange that they did not meet a big man, nor did they encounter some strange things, not even some traces of fighting.

This means that they are still in the outer area, and they are riding small electric vehicles, although they are not as fast as the motorcycles outside, but they have been in a state of jogging, and after thirty or forty minutes, it still seems that there is no difference between the underground access when they first entered.

They all had the illusion that they were in a daze after dozens of minutes.

But Lin Zhen knew that this was not an illusion, and the power loss on the small electric car and tablet told him very clearly that none of this was an illusion.

Lin Zhen was helpless, and hurriedly changed to a small electric car with Wang Shi, and the lights were still a little power loss.

He continued to drive in front, but the car was replaced by Wang Shi's, so that the power of the four cars could be guaranteed.

Chu Lang and Li Tianqiang, who were in the back, exchanged cars and continued to be at the back of the line, illuminating the situation in front.

Walking all the way forward, there is no sound in the passage except for the roar of the motor of a small electric car.

The four of them stopped to observe the navigation map when they changed cars, and they were already two-thirds of the way from the entrance, and they were still one-third of the way to the end of the edge of the passage plan, which was the position where the two hundred big men had moved before.

They hadn't been to the area yet, which meant that they were likely to encounter two hundred men armed with thermal weapons.

You have to speed up, and if you can follow those people, it's safer to move forward.

Lin Zhen thought secretly in his heart, and constantly accelerated the speed of moving forward, and the positioning signs on the tablet continued to pass through one passage after another, approaching the field of vision of the floor plan.

Half an hour later, Lin Zhen motioned for everyone to stop.

The other three walked up quickly, looking at the indicator map on the tablet, and their position was presented on the navigation map, which was already the edge of the field of view, which meant that, further on, was the area of the location.

The data on the fox's side has no source support, and they can only grope forward on their own.

Wang Shi looked at the left and right directions and said, "Those people have either given up filming and surveillance, or they have left in the left and right directions. ”

Li Tianqiang said: "Maybe those people have fallen into this place full of forks and lost in this dark night. ”

Chu Lang said: "This is very dangerous, once we lose our direction, then it will become very dangerous next, if we don't have the navigation map guidance of this tablet, I'm afraid we will have been lost in this dense underground passage." ”

Even if they return along the road now, they can't find the way anymore, and they have to be guided by a navigation map.

Lin Zhen glanced at the signal on it, took out his mobile phone and checked the signal source, there were already two squares left, and said with some concern: "If you go deeper, I suspect that the signal source will disappear, and then we will be like them." ”

"So what now?"

Wang Shi frowned, they hadn't met anyone until now, and they felt as if there were only four of them in this underground passage.

After going so far, the air still didn't feel stuffy, and the temperature became cooler.

This made them secretly feel surprised, and kept the changes here.

Now that they're starting to get a little tangled.

Lin Zhen hurriedly dialed the fox's phone, and the two signals could still be dialed.

"Now that we've reached the edge of the visual navigation map, there is no update on your side, give us a reference to the next action."

The fox said: "No, only some of the previous group of more than 200 people are moving, but moving to the left and right, I suspect that some people continue to go deeper, but the signal source can no longer be transmitted, so there is no depth of vision channel." ”

In this case, we will also lose contact with each other.

Lin Zhen frowned, if there was no technical support from the fox outside, it would really be very dangerous for them to break into this underground passage, once they couldn't leave within seventy-two hours, then they would be starving in this endless dark night.

"Did you find anything along the way?" The fox asked.

"No, it's always been a stone-paved underground passage, and we've already penetrated it straight through." Lin Zhen said.

The fox was silent for a while, and said: "I suspect that this underground passage, the scope of your activities along the way, is only the periphery, continue to go deeper into the inner perimeter, the royal tomb should be in the core area." ”

"Are you saying that this royal tomb is divided into three layers inside and out, and we are now in the outermost area?"

The fox said, "Yes, you should be at the edge of the outermost end now, and you should be at the inner perimeter when you go inside." ”

After chatting with her for a while, Lin Zhen ended the call and told Chu Lang and the others about the latest news and some guesses.

After listening to this, the three of them all felt the seriousness of the matter.

Along the way, they drove the small electric car for about an hour and a half to the end of the edge of the perimeter, and there were two floors inside, and if it was so complicated, they didn't have to expect to be able to get to the core area, and they didn't expect to be able to pass through the inner area.
