[Tomb Raiders Notes Sand Sea] Into the Red Dust

, so Gu Ran shouldn't have come.

"What do you remember?"

Zhang Qiling stopped talking.

Gu Ran had a vague guess in his mind.

Copy of Zhang Family Ancient Building 3

After a few hours, everyone came back one after another. As expected, they found nothing.

Huo Xiangu suggested walking back to the entrance from the outside and walking again to see what went wrong.

Gu Ran also agreed with this idea, although he guessed that the password of the third stone wall was wrong, but he couldn't figure out why it was wrong.The password of the third stone wall is logically unreasonable here, and his later speculation about the error protection mechanism is invalid.It just so happened that Huo Xiangu's proposition allowed him to confirm whether the password was really wrong.

So they climbed over the mountains, returned to the entrance again, passed three stone walls again, and saw the sun again.

The difference is that they came out from another exit and went to another mountain.

"Why did you change the location? Could it be that when we were leaving, some mechanism in the tunnel changed its direction?" The fat man asked, "Brother, Gu Ran, did you find anything?"

Although Gu Ran boasted that his perception was not weak, he couldn't find anything.This made him feel a little bad. This kind of mechanism that made him completely unable to perceive the movement and hear the sound was also encountered in the Xisha Undersea Tomb.

Zhang Qiling also shook his head.

The members of the Huo family began to feel a little anxious. Since entering the mountain, the things they have experienced are too bizarre, which have exceeded their cognition, and they can't help but feel the fear of the unknown.

Whispering starts with a few young guys and spreads fear.

"Be quiet and listen to me." Gu Ran said in a deep voice.

Gu Ran talked about the error of the third stone wall mechanism and the inference of the fault tolerance mechanism.

"So the question now is, how many times does the fault tolerance mechanism you mentioned have?" The fat man concluded, and then asked, "Brother, you know it best, what do you think?"

Zhang Qiling pondered for a moment, seemed to think of something, and then said: "Let's go again."

Huo Xiangu believed in Zhang Qiling's judgment, beckoned her fellow to follow, and walked back to the entrance.

The process of entering this time was almost exactly the same as the previous two times, but the speed was slower. They searched the stone wall almost inch by inch. Zhang Qiling's fingers touched almost any place on the stone wall, but found nothing.

Gu Ran was still the first one to notice something was wrong.

He calculated the distance they traveled each time. Based on the previous two failures, he speculated that these caves were built by the mountain itself. The ancestors of the Zhang family used these karst caves in the mountain to create mechanisms to protect the ancient building of the Zhang family.

The area of ​​the Zhangjia Ancient Building will not be very large, so this mechanism will not cross several mountains. The previous two times they walked out from a mountain adjacent to the entrance. This time it should be the same, and the Zhangjia Ancient Building, In these mountains of blindness.

The distance between the mountain tunnels will not differ by more than 500 meters. He observed it when he was on the top of the mountain before. The nearby mountains are similar in size, and the mountain tunnels they walked three times are almost straight without many bumps.

But Gu Ran clearly felt that their journey this time was more than 300 meters longer than the last two times, but they never saw the sun.

Gu Ran found that the visible distance of sunlight is 200 meters. From this point of view, this tunnel will be one mile longer than the previous two.

It's almost impossible.

"Wait." Gu Ran held Zhang Qiling who continued to walk slowly forward, "Something is wrong."

The traveling speeds of the three mountain crossings were different. The first time was a normal speed, the second time was a rapid march, and the third time was quite slow. This greatly affected people's judgment on the distance. Therefore, except for Gu Ran, even Zhang Qiling did not make it so clear. Be aware of distance issues.

"According to what you said, we went the wrong way again this time?" The fat man asked, "Do you think it is possible that we accidentally triggered some mechanism, a blind cat bumped into a dead mouse, and found the right place? No, it means we didn’t go outside the mountain.”

Gu Ran shook his head: "Do you think the Zhang family will give you a chance to run into a dead mouse?"

Fatty thought it was impossible, so he asked, "Then what should we do now, go forward or go back?"

"It's all right. If you go forward, you can see what's ahead. Going back...is nothing more than going back to the entrance, then contact Wu Xie and Hua'er, and ask them to re-confirm the mechanism of the third stone wall." Gu Ran looked at Zhang Qiling, "What do you think?"

Zhang Qiling said: "Go forward, everyone be careful."

The road ahead was not long, and it didn't take long to reach the end. A stone wall appeared in front of it, which was a dead end without any mechanism.

The fat man couldn't help but glanced at Gu Ran. The latter's face was heavy, and he knew immediately that something had happened.

According to Gu Ran's inference, the fault-tolerant mechanism has a limit on the number of times. If it is still within the fault-tolerant mechanism, then they should still see sunshine.If they are outside the fault tolerance mechanism, they should go to a deadly mechanism, not a stone wall with nothing.

The front is a dead end, normal people would know to turn back, if this is the anti-theft mechanism of the ancestors of the Zhang family, it is obviously too childish.

Although Fatty doesn't like to use his brain, he can guess now that they probably won't be able to return to the entrance.

For a moment he remembered that there was something wrong with Gu Ran's tone when he discovered the problem just now. He paused for a while when he said that going back was nothing more than returning to the entrance. Most likely, this guy guessed the problem at that time.

It's just that they can't say that the big army is the Huo family's buddies, and their trust in Zhang Qiling is low, but now they have fear and suspicion. If something happens again, people's hearts will disperse.

The fat man chose to remain silent. Although Gu Ran and Zhang Qiling knew they couldn't go back, they still decided to go back.

The speed of the quick march was very fast, and seeing a stone gate from a distance, the fat man thought they had really returned to the entrance, doubted the speculation just now, and turned his head to see that Gu Ran's expression was still not good.

After walking through the stone gate, they found that this was not the place to come in, but led to another strange cave.

This cave is full of pools and pits.

Gu Ran stood at the entrance of the stone gate, frowning in thought, while the fat man entered the pool with a few guys. It was not deep, and there were a lot of bones at the bottom.

The fault tolerance mechanism failed, and they entered a dead end.

The bones at the bottom of the water are obviously the tomb robbers who explored the Zhang family's ancient building before.

There is no agency here, how did these people die?Gu Ran pondered, the biggest possibility is that, like the tomb under the sea, ghosts hit the wall and were trapped to death.But why did the bones appear only here, but not at the other end of the tunnel?

After a while, Gu Ran felt that the air around him was not right, and he was shocked: "There is something wrong with the air, it is poisonous gas."

Now everyone has become a frightened bird, for fear that they will die here, they would rather believe it or not, so they hurriedly took out their gas masks and put them on.After a while, they discovered that the poisonous gas here was so corrosive that it could be directly absorbed by the skin, and Huo Xiangu had already bled subcutaneously.

Zhang Qiling immediately said: "Back into the tunnel and block this place."

At this time, the Huo family had already distrusted Zhang Qiling. Through the previous three passages, Zhang Qiling was [-]% sure that there was no mechanism, but they led to different mountains each time.They don't know whether they should go back into the tunnel. What if the tunnel changes again and something else comes out?

"Listen to him, go to the tunnel, if you encounter any tricks, if you stay here, within four hours, everyone will die." Gu Ran said in a deep voice.

Huo Xiangu already felt a strong discomfort. She knew that the poisonous gas was fatal. If she stays in the cave, she will die. If she goes out of the tunnel, she still has a chance of life. Therefore, she suppressed the guys with Jiwei, and everyone retreated into the tunnel. It took everything to block the tunnel mouth.

The next few hours were quite difficult, and they reached the end of the tunnel again. It was still a dead end, but it was obviously different from the previous stone wall, and the exit of the tunnel was moving.

Huo Guy's plan is on the verge of collapse.Fatty put forward the method of brute force just like Xisha Undersea Tomb, Zhang Qiling denied the existence of the mechanism, and Fatty suspected the corpse.

The fat man burned the golden talisman, but this time it had no effect at all.

It's not a ghost hitting a wall.

Almost everyone doubted Zhang Qiling's judgment.

Whether there is an agency is a good proof. They brought a lot of explosives and found several points to blast.

The stone wall here is surprisingly easy to explode, and the fat man blew up a large part, but there is no space behind the stone wall to hide the mechanism, it is all stones.It is impossible for the mechanism to be buried behind such a deep stone wall, and it cannot function.

It's not a mechanism. This is a heavy blow to all the Huo family. In their previous concept, it was Zhang Qiling's judgment that there was a problem. If there was a mechanism but he didn't find it, he would be trapped in the current situation. As long as he found the mechanism, There is still hope.

But the only belief that supported them was falsified. The people from Huo's family almost collapsed. After all, Huo Xiangu has experienced a lot and can still support her spirit, but she is old and her mobility is almost zero.

"Try Wu Xie's mirror theory." Gu Ran said, "At that time we were in a closed loop, and he said that if there are overlapping spaces, people walking in the tunnel will definitely see the overlapping spaces. We are similar now, if The exit of the tunnel is moving, one of us is at the entrance, one is at the exit, and another person walks from the entrance to the exit, then the two people at the entrance and exit may see the truth of the movement of the tunnel.

This is the only way to solve the current predicament, and both Zhang Qiling and Fatty agree.

Throughout the team, keep enough
