As the two door-sealing stones fell from above, the main burial chamber we were in was instantly sealed!

Xiao Liang exclaimed in surprise and said anxiously: "It's over, it's over, we're trapped inside!" ”

Jiang Yongguang's face also changed, and he said in a deep voice: "It's broken, it seems that we opened the wrong coffin, I didn't expect the owner of the tomb to be so ruthless, and he directly dropped the sealing stone to lock us underground!" ”

Lao Wei glanced at the coffin in front of him and hurriedly asked, "Why don't we quickly close the coffin?" ”

According to the normal way of thinking, since the result of opening the coffin is to fall the sealing stone, will the sealing stone be lifted up when the coffin is re-covered?

Jiang Yongguang glanced into the coffin, and saw that there were no remains or burial goods inside, it was an empty coffin, so he immediately nodded and said, "Yes, hurry up and cover the coffin again!" ”

After speaking, the four big men pushed the coffin lid to cover it again at the same time.

When the coffin lid was moved, I clearly heard a "squeak" sound, and it stands to reason that the friction between the coffin lid and the coffin body is not so big, as if the coffin is connected to other mechanisms.

When the lid of the coffin was closed again, we looked at the doorstones on both sides, waiting for them to be lifted again and let us out.

But at this moment, something even stranger happened, instead of lifting the stones on both sides, the wall on the north side of the main burial chamber suddenly rumbled, and it shook and advanced three feet away from us!

I was dumbfounded, why is this different from what I expected?

When the coffin was re-covered, not only did the sealing stones on both sides not be raised, but the walls were moved, and the space of the main burial chamber was reduced again!

"What's going on?" Uncle Mei's eyes widened and asked, "Why did this wall come over?" ”

Jiang Yongguang was also stunned, and it took a long time before he walked over to take a look at the moving wall, squatted down to check the ground, and then said with a pale face:

"Oh no, the four walls of this tomb are all movable, and this seven-star coffin should be the switch that activates them, once we open and close the coffin, the walls will move with it."

Lao Wei said speechlessly: "But we opened Tianxuan's coffin, and the sealing stone fell, and we closed Tianxuan's coffin again, shouldn't it be to lift the sealing stone?" ”

"I'm afraid it's not that simple." Xiao Liang shook his head and said, "If each coffin corresponds to a separate mechanism, then what you said is true, but if these seven coffins form a composite mechanism, then it is impossible to achieve the opposite command through one opposite operation." ”

After hearing this, Lao Wei scratched his head and frowned: "Xiao Liang, what do you mean by this?" ”

To be honest, I didn't understand Xiaoliang's words, and I felt that what she said was a bit profound.

Xiao Liang explained again: "At present, these seven coffins should form a composite mechanism, if it is regarded as a combination lock, the action of opening and closing the coffin can be regarded as the password for us to leave the main tomb, but at present, we don't know how many digits this password is, it may be one, that is, we only need to open a coffin to unlock the password, but it may also be seven, that is to say, we must open seven coffins in a row to successfully leave here." ”

This time she said it very clearly, and I finally understood what she meant.

Jiang Yongguang frowned and said, "If this is really the case, then this mechanism is too complicated, how can we successfully try out the password?" ”

Lao Wei looked around anxiously and said: "Now that the main tomb is sealed, the air will soon run out, if we can't crack the mechanism as soon as possible, everyone is afraid that we will suffocate to death in the tomb!" ”

Hearing Lao Wei say this, everyone became more nervous, and several other Xiaoling guards were also anxiously scratching their ears and cheeks, there was no way.

Uncle Mei frowned even more, and said in a deep voice: "Alas! It's a pity that I don't have a lot of strength, but my brain is not very good, and I'm afraid I won't be able to help much this time. ”

Only Xiao Liang was calmer, looked up at Jiang Yongguang and Lao Wei and said: "Two seniors, one of you is proficient in tomb structure, and the other is proficient in feng shui knowledge, don't panic, calm down and think about it, we will definitely be able to think of a way to crack the mechanism." ”

I knew that my IQ was limited, and I was afraid that I couldn't help them, so I could only cheer them up and say, "That's right, since those tomb robbers are not here, they must have cracked the mechanism and entered the secret passage." Since those rats can crack it, we will definitely be able to crack it too! ”

As a result, my words woke up Jiang Yongguang at once.

He slapped his head and said, "That's right! Xiao Chen, you said it well! Since Yang Guo and the others are not in the main tomb, and there are no corpses at the scene, it means that they have cracked the mechanism and entered the secret passage! We don't have to do this question ourselves, we can copy the answer! ”

"Copy the answer?" I was curious and asked, "How do you copy the answer?" ”

Jiang Yongguang pointed to the Tianxuan coffin we opened just now and asked, "Look, this coffin is open and closed, what has changed?" ”

I bent down to take a closer look, and immediately understood, pointed to the coffin and said: "The coffin lid is connected to the mechanism, and the force of eating is relatively large, and pushing the switch will leave scratches on the coffin!" ”

"That's right, it's a scratch!" Jiang Yongguang said, "Since Yang Guo and they have successfully cracked the mechanism and entered the secret passage, then we look for the scratches on the coffins, don't we know which coffins they have opened?" ”

"That's right!"

When everyone heard this, they immediately looked down and looked at it.

Uncle Mei was the first to find the scratch, pointed to the coffin placed in the Kaiyang position and said, "This coffin has been opened!" ”

Lao Wei found it the second, pointed to the coffin at the Tianshu location and said, "This also has scratches!" ”

Xiao Liang was the third to find it, and the coffin she found was Yaoguang, she raised her hand and said, "And here, Yaoguang's coffin also has scratches." ”

From this point of view, three of the seven star coffins have scratches, which means that the "password" to open the mechanism is three digits.

But at this time, I questioned: "Wait, Officer Jiang, is it possible that the coffin of Tianxuan that we opened just now has also been opened?" After all, you can't guarantee that the scratches on it were opened by us, or by Yang Guo and them before, right? ”

Jiang Yongguang shook his head and said: "I don't think this coffin has been opened before, because when the coffin was opened just now, the coffin lid was very jerky, not like it had been opened, and it was dusty when the coffin was opened. ”

As soon as I heard this, I immediately agreed, "That makes sense." ”

Observe Jiang Yongguang carefully and remember the details when the coffin was opened, otherwise it would be easy to make mistakes.

At this time, Lao Wei asked: "Okay, now there are three coffins that are locked correctly, Xiaoliang, three coffins are arranged and combined, how many orders are there for opening the coffin?" ”

Trabecular's answer was almost instantaneous: "Six combinations, that is, we have to try six times." ”

I couldn't help but give her a thumbs up: "Good guy, you're too fast, aren't you?" ”
