Judging from the recovery of the wound, Qi Ziyu's injury does not look like it was caused not long ago, but like a wound that was almost healed a few weeks ago.
Just based on the speed of his wound healing, he could have been taken away as an experimental subject.
Zhou Sheng shook Qi Ziyu's body, trying to wake him up while avoiding touching the wound as much as possible.
But Qi Ziyu seemed to have passed out. No matter how Zhou Sheng shook, there was no sign of waking up.
Qi Ziyu must know more truth. For example, why the entire tomb is guiding people to complete the process on the murals and finally enter the main tomb, but the mysterious things in the tomb are calling them to leave.
For another example, why does every seemingly sinister mechanism contain a hint of hope and hope?
Assuming that the human-shaped airflow just now was the embodiment of "Madam", what is echoing in the corridor now is also Madam's voice.
Then the lady and the builder of this tomb are most likely to have a hostile relationship with each other.
However, according to Qi Ziyu's description at that time, the funeral affairs of the General's Mansion were handled by his wife, and even this tomb may have been created by her.
Then why did Madam fight against herself?
Too many mysteries lingered in Zhou Sheng's mind. He seemed to be standing in a maze. He had just discovered the direction to the next intersection, but soon saw that there were countless branches at the next intersection, as if forever.
It is also difficult to reach the end.
Zhou Sheng tried to call the professor and students a few more times. The professor was the most deluded, and there was no response no matter how Zhou Sheng called.
However, Xiao Zhang quickly woke up in Zhou Sheng's voice. He looked at Zhou Sheng and asked blankly: "Boss, what happened just now? Why am I standing here all of a sudden?"
Seeing that he regained consciousness, Zhou Sheng began to call Xiao Wang, but within a few seconds, Xiao Zhang's eyes became dull again.
Liu Ruyan said: "It seems that only when your voice overwhelms this call can they be temporarily freed from the influence of the bewitchment."
Liu Ruyan was sitting next to a few people at the moment, leaning against the wall and taking a short rest.
She had already wiped away the blood stains on her lips, and although her face was pale, she did not show any pain.
With her physical condition, she would not be unable to take full action after being hit hard. But after returning from this trip, she would inevitably have to rest for a while.
But at least until the action is over, she cannot allow herself to be a hindrance!
Zhou Sheng nodded and agreed with Liu Ruyan's judgment: "I'm afraid the collapse of the corridor will be the same. The collapse will only stop when the shouts cover up some kind of sound that we can't hear."
Since the key point of the entire tomb is sound, Zhou Sheng can naturally think of the means of causing the collapse by sound.
Liu Ruyan asked: "The inaudible sound? Could it be ultrasonic or infrasound waves?"
Zhou Sheng said: "I have heard before that infrasound waves with a certain special frequency can cause resonance in the soil and artificially cause small-scale earthquakes."
"It's just that due to the limitations of infrasound wave transmission, it is generally difficult for earthquakes to reach a level that attracts people's attention, and the earthquake sensation is also very weak."
In addition, machines that generate large-scale infrasound waves are extremely expensive to build and cause little damage, so no one, not even terrorists, will use this method to cause damage.
After all, it would be more practical to spend a lot of money and energy to create infrasound waves with a unique frequency than to just drop two bombs.
Liu Ruyan added: "But under the originally empty ground, the resonance of the soil layer can easily cause landslides."
"And such a large-scale plan will definitely be discovered. After all, there is nowhere to hide a large infrasonic machine."
In other words, this method seems unexpected, but in fact it is easy to track and discover.
If you just want to cause the tomb to collapse, there are too many more effective methods to choose from!
The only advantage of this method is that the plan can be stopped at any time through interference sounds before the collapse is completely uncontrollable.
Of course, if you want to disrupt sound waves of a specific frequency, you also need a special wave band.
Ordinary people's normal shouting is unlikely to interfere with infrasound waves.
But in the main tomb chamber, the call of the inhuman thing may have happened to form a special wave band!
Liu Ruyan's eyes flashed and she looked at Zhou Sheng: "I suddenly thought of the message Bai Feifei sent before. Do you think she stopped us from going to the tomb because she discovered Tianzun's plan to destroy the tomb?"
"It's very possible." Zhou Sheng also had this speculation, but in a place like the underground where there was no signal, he could not receive any follow-up messages from Bai Feifei.
If Bai Feifei hadn't discovered the plan, how could she, who was dozens of miles away, know what kind of danger Zhou Sheng and the others would encounter in the tomb?
Moreover, if using infrasound waves to cause landslides was a method that Tianzunhui planned early on, then Wei Ping's calmness in the face of the vibration can also be well explained.
I'm afraid they have already tested how long it will take to use infrasound waves to cause resonance before the collapse enters an uncontrollable stage.
And before the time is up, they can stop the resonance at any time, so Wei Ping is naturally confident!
If the Tianzun Association's actions are a line, then the puzzles on this line have gradually been solved and become clear.
But in this tomb, there is obviously another intricate line, which is intertwined with the actions of the Tianzun Association, forming a confusing web that makes people confused.
That was the truth hidden in this tomb back then!
Zhou Sheng originally wanted to find this answer from Qi Ziyu, but unfortunately Qi Ziyu still showed no sign of waking up.
He had no choice but to look at the sealed admonition in his hand. This thing should also be able to give him the answer!
Zhou Sheng opened the letter of remonstrance. Since it had been sealed in the tomb chamber that lacked oxygen for many years, the writing on it had not been oxidized and could be read very clearly.
On the first page of the death remonstrance book, there are eight big words written in blood: "I will never have any second thoughts, and I will make my will clear through death!"
This handwriting is arrogant and unrestrained, but it also has the beauty of uninhibited regularity. It is obvious that he had some attainments in calligraphy during his lifetime.
Judging from the handwriting, the person who wrote this book seems to be the general himself.
The calligraphy of that era was also in full bloom, and regular script was one of the mainstream.
Therefore, the remonstrance written in Xingkai font is reasonable, and for modern people, there is not much obstacle to reading.
In addition to the blood words on the first page, the following is a detailed explanation of the ink letters.
Zhou Sheng read it carefully and found that the gist of the death remonstrance was that the general was crying about his grievances. He said that someone had previously accused him of secretly forging weapons and intending to rebel, which was purely a false accusation.
He hoped that the Lord would send people to his mansion to conduct a strict search, and that he would be treated as a suspect and thoroughly investigate the entire clan.
