The others had no opinion, and once again got ready to go, started the small electric car, and continued to move forward with a roar.

In less than five minutes, their signal source was completely cut off.

Lin Zhen had to put away the tablet and said to the three of them: "We can only leave marks along the way now, if we fall into a puzzle, we will follow the marks and return!" ”

Wang Shi asked in surprise: "By the way, why didn't we find the marks left by other people along the way, it stands to reason that they should also think of this way, don't they think they are lost?" ”

Chu Lang said: "I don't know, maybe they didn't take our road, after all, there are so many forks along the way, one is divided into two, two is divided into four, and four is divided into eight, even if more than two hundred people come in, they may not be able to go to the same channel." ”

"But there was a damp and cold breath in the air, and there was no smell of gunpowder smoke and blood, so there was no gunfight in this area we walked over?"

This is indeed a question, but it comes down to that reason, there are too many passages here, we may have taken a different path, and it is also very likely that they did not encounter an opponent, so naturally there would be no shootout.

Along the way, the four of them raised some doubts with each other, but they did not have a better understanding and explanation for each other, and all of them toppled the passage they were walking on, and no one else had walked before.

At this time, the signal source has been completely lost, they go forward fifty meters, as long as they do not encounter a fork, they will mark it directly, mark it at the fork, find the direction of the other party, and then go to select one of the fork channels.

For the four of Lin Zhen at this time, they are full of trembling, the four of them are also considered to be masters of the arts, and they have also undergone various strengthened military physical and psychological training, sneaking up to the current problem, they all feel that this is an endless channel.

Now they have the tools to walk on their behalf, and it is easy and easy to walk, so they simply take two mouthfuls of water on the way, and then continue to set off after a short break.

I have been walking for more than 40 minutes, and if I convert it to the J City sub-district, I have completely walked from one sub-district to another, after all, the speed of a small electric car is equivalent to the speed of a marathon jogging.

They stopped again, because the end ahead had already made a bet.

In the process, they have gone through more than a dozen ends, each time returning to the previous fork in the same way, marking it before moving on to the next fork.

But over time, they all felt like they were walking around in the same place.

Now they had another end of the passage and had to stop.

"Qinglong, why don't we try it, can we dig out one or two stone slabs and see if they are really solid?"

Lin Zhen didn't answer him, he came directly to the stone wall at the end of the road, and struck the end of the dagger a few times.

Knock knock!

Surprisingly, they had knocked a few times before, and their voices were very dull and thick, but now there was a different feeling of knock knock void.

The faces of the four of them were overjoyed and incredulous.

Fortunately, Chu Lang said more, and they did not become numb because of the previous dozen or so strokes, and gave up such a seemingly redundant move.

Just like a person who is looking for bricks and stones from hundreds of millions of grains of sand on the beach by the sea, picks one up, finds that it is not masonry, and throws it into the sea, picks up one, no, and throws it into the sea, when it lasts for countless days and nights, that person really picks up a brick and stone, but subconsciously throws it into the sea.

Such a scene is similar to the behavior of the four of them now, but they have only done it a dozen times, and they have tried to hit it every time.

Unexpectedly, this time, there would be an unexpected gain.

Chu Lang and the three of them got out of the car one after another, quickly came to the stone wall, and observed with them.

After a while, Lin Zhen pointed to the two large stone slabs and said, "On this cliff, the echoes of the other big stone slabs are not the same, but these two big stone slabs are relatively close to each other. ”

Li Tianqiang said: "Since this is the case, let's focus on these two big stone slabs." ”

The four of them dug with daggers for a while, and like the previous situation, they couldn't dig it out at all, this is a tenon and tenon structure, which cannot be opened from the outside, unless a strong external force crushes the mortise and tenon inside.

"How?"

Wang Shi wondered and asked, "Can the bullet penetrate it?" ”

Lin Zhen narrowed his eyes and said, "Try it!" ”

"In that case, let's go crazy, it's better to attract some people to come, and ask about the news they got, and now we are blind here." Li Tianqiang grinned.

The four retreated some distance to avoid stray bullet injuries.

Wang Shi held an assault rifle and shot wildly at the two boulder plates that had been identified earlier.

Da-da-da-da!

Bang bang bang!

Bullets were densely ejected on those stone slabs, sparks flew everywhere, and bullets flew wildly.

After a while, the sound of the cartridge hitting the empty chamber sounded, and the four of them walked over with anticipation on their faces, and came to the stone wall at the end of the passage.

In the light of the light, they saw that the boulder slab had cracked countless cracks, and some bullets were embedded there, but they still couldn't penetrate it.

Lin Zhen used a dagger to constantly pick out the gravel, and kept disassembling the stones one by one.

After a while, two rocks were cleared, revealing some dirt, but it looked dry.

Lin Zhen stabbed with the dagger a few times, and constantly dug out a lot of dirt, and after he was vigorously drumming for a while, suddenly there was a pop, and the dagger pierced through a piece of dirt, and a space appeared.

Hey!

"It's been discovered, and it seems to be able to lead to other places." Wang Shi said excitedly.

Chu Lang also said excitedly: "Is this another spring, this passage should be different from what we have walked through during this time." ”

The four of them hurriedly dug up the boulder slabs, and after a while, they finally removed the four boulder slabs, and the vibration of the dense bullets broke some of the mortise and tenon structures inside.

Lin Zhen hurriedly turned on the searchlight at the helmet, swept it in for a while, and found that it was very open inside, and he didn't know where it was leading.

Chu Lang asked: "With our current situation, I think we can go in and break in, leave some markers, and estimate the time, if we don't arrive at the royal tomb within thirty hours, we can only give up moving forward and return along the road." ”

Wang Shi nodded and said, "I also agree, the temperature inside seems to be lower, it may be in a terrain below the comparison, or it may be leading to the core of the place." ”

Lin Zhen pondered for a moment and said: "Okay, let's transfer these passages, after all, along the way, we have encountered more than a dozen walls, only here is hollow, and now there is such a road, there should be different discoveries." ”
