A device like a walkie-talkie is very convenient to use outdoors.
However, because it uses electromagnetic waves to transmit information in the radio frequency band, the probability of interference is very high in areas where electromagnetic waves and magnetic fields are relatively chaotic.
It is very possible to "catch up" with other people's frequencies, which is commonly known as "crossing the channel."
Previously, when they entered this floor, their walkie-talkies were disturbed and they all fell down together.
Listening to what Old Wei meant now, before that, he had received a voice from the walkie-talkie, asking him to put down the walkie-talkie and go join the large army.
As for the source of that sound, it is now certain that it was definitely not Lin Yi.
Anyone who was there can attest to that.
"In other words, Lao Wei was attracted by the voice on the walkie-talkie, and then left the agreed place. Then he was used by Yu Wenrui and became his puppet."
"That thing is like a carrot turned into spirit. How can it still have so much energy?"
Lin Yi thought for a moment.
He shook his head decisively.
"Although Yuwenrui can learn about the situation in the cave through sound vibrations, he can also affect the communication between us through the unique magnetic field underground.
However, it was absolutely impossible for him to simulate the signal of a walkie-talkie and then emit a frequency similar to human voice to interfere with Lao Wei's judgment. "
"Yes, if it has such ability, why would it end up like this?"
"Consultant Lin, what do you think is going on, Master?"
"Lao San just analyzed it with me. The reason why Old Wei was so targeted by Yu Wenrui is because he may have Xianbei blood.
Lao Wang also said that the reason why Yu Wenrui ended up like this was thanks to Tuoba Mu from Xianbei, so he was the most seriously injured.
As for the intercom signal, it was most likely that he inhaled too much fog in the tunnel, causing his senses to be disturbed.
Even though he was out of the pit, he was still affected. "
After everyone listened to his explanation, they all thought about it in their hearts.
After reviewing all the causes and consequences, this statement is quite convincing.
Even Lao Wei himself felt that he might have had a hallucination before, which triggered a chain reaction and led to a series of subsequent events.
"Coming out of that tunnel, I did feel a little dizzy. As for the bloodline, I really don't know."
"It doesn't matter if you don't know. This is just our speculation. Let's rest for a while. You are more injured than them. Don't come down and move around for the time being."
Old Wei nodded, took a few sips from the water bottle, and lay back on the stretcher.
When they walked away, Bai Lu waved to Lin Yi and called him over.
"Brother Lin, why do I feel that this matter is a bit strange? I have used this handheld device many times. There are cases of tampering with the platform, but it is not common. Moreover, Lao Wei is also an old criminal investigator. Even if there is slight poisoning, this I should still have some sense of judgment.
Do you think there really is another radio signal here? "
Lin Yi frowned.
"Just say what you think."
"Remember that little advance team that got lost in a hole in the ground?"
After her reminder, Lin Yi suddenly reacted.
I had been in a state of tension just now, and all kinds of things were mixed together, so I completely forgot about this matter.
According to their previous speculation, all of this special team should have died in this underground cave full of mechanisms. Not only were there no survivors left, but there were not even any unnecessary traces left behind.
Therefore, the guy named Gong sneaked into the Ganlong area in the name of supporting education. By studying Yu Wenrui's family history, he actually wanted to find the hidden soldier cave built by Zhang Ji and Yu Wenrui.
Its real purpose is to find the advance team that secretly entered the country.
If these speculations are true, the motivation of the advance team is not just to explore the road, but there should be other purposes.
Thinking of this, Lin Yi moved his gaze to the top of his head.
The current passage is a secret passage that was reopened after Yuwen Rui's repairs.
Above the head is the original site of the Tibetan Soldier Cave built by Zhang Ji.
Judging from the traces encountered before, this small-time advance team not only failed to find the correct way out, but also failed to find the existence of Yu Wenrui's secret passage.
The end result was the annihilation of the entire army.
"Could it be that this is a 'ghost signal'?"
"This possibility cannot be ruled out. Many overseas explorers have recorded stories about ghost signals in their travel notes. For example, when they suddenly received a radio distress signal on the sea, they searched for the past time based on the coordinates it conveyed. Nothing was found at all, but later it was discovered that there had been a sunken ship in that sea area.
Some people who go to places like the Grand Canyon and caves will also be interfered by some kind of radio signal. In the end, they learn that an expedition team has arrived here, and all the members died in the end.
So Westerners call it 'ghost signal'. "
Bai Lu recounted the rumors about "ghost signals" she heard when she was in school.
Lin Yi is also thinking about this issue now.
The so-called "ghost signal" is a special magnetic field scene. They have encountered stranger things than this, so this concept is not strange to him and is acceptable.
At this moment, Wang Qiang in front suddenly turned his head and waved the walkie-talkie towards Lin Yi and the others.
"Old Lin, we've received another signal here."
Lin Yi immediately turned on his walkie-talkie, and a squeaky voice came from it, and then he vaguely heard one or two unclear human voices coming from it.
The complete sentences are not coherent, but a few key words are fairly clear.
"Put it down, turn around, return, big troops, assemble!"
Old Wei, who was lying on the stretcher, suddenly reached out and patted the frame of the stretcher.
"Yes, that's the sound. I heard it before."
"Are you sure it's this sound?"
Old Wei closed his eyes and listened carefully, nodding slightly.
"It's probably this sound. It may be what Consultant Lin said. Because the poisoning affected the senses at the time, the brain judged that the sound was made by Consultant Lin."
"There is a possibility that in the case of poisoning, the brain will automatically complete the information based on the previously processed information. Lao Wei and I had just separated, so he thought these messages were sent from me.
It's actually caused by other signal crosstalk. "
"So where do these signals come from?"
Everyone was confused.
Lin Yi pointed at the top of his head.
"It should be above our heads. Let's keep walking forward and always pay attention to the strength of this signal. Once the signal becomes clear, we will go to the top and have a look." (End of Chapter)
