Frequency detection is not troublesome, because the use of detection equipment is very advanced.
However, Chen Hui didn't detect any frequency when communicating with Cheng Ziyi.
Now that it has been tested, it's natural to test comprehensively. Chen Hui enters the field of divine consciousness and takes Cheng Ziyi into it. About five or six minutes later, Chen Hui exits the field of divine consciousness and asks Zhou qiuchu if he has detected the frequency.
The results were the same, and no frequency was detected.
"Cheng Ziyi controls the flying sword with his mind." Chen Hui was not surprised by this result. He said to Zhou qiuchu, "Shangguan Ruyun once said that ideas can be understood as the thoughts of ordinary people, and I don't think it's strange that frequency can't be detected. According to Shangguan Ruyun, the detection of frequency is not different from the detection of people's thoughts."
"It's just the beginning!" Zhou qiuchu nodded and said, "it's because you know that you can enter the field of divine knowledge that you bring these devices. The purpose of detection is to determine whether the frequency of the field of divine knowledge exceeds the frequency of brain waves. Next, we need to carry out the detection of brain waves."
EEG is a method of recording brain activity by using electrophysiological indexes. When the brain is active, a large number of neurons synchronously generate postsynaptic potentials, which are formed by summation.
It records the changes of electric waves during brain activities, and is the overall reflection of the electrophysiological activities of brain nerve cells in the cerebral cortex or scalp surface.
Brain waves come from the postsynaptic potentials of the dendrites at the top of pyramidal cells.
The formation of EEG synchronous rhythm is also related to the activity of the non-specific projection system in the cortex and thalamus.
EEG is the basic theoretical research of brain science, and EEG monitoring is widely used in clinical practice.
Scientific research has found that four types of brain waves correspond to four different states of the brain.
When you feel sleepy under tension, when you enter deep sleep, when your body is relaxed, your brain is active, and your inspiration is constant, the activity of brain waves is different. They are marked by different bands, and the frequency band is also different, marked by Hertz.
In this car, there are two brain neuron wave detectors. It's obvious that experts from Zhou qiuchu's department have already considered them.
Soon, these two brain neuron wave detectors were put on the heads of Chen Hui and Cheng Ziyi, and began the second detection.
When Chen Hui and Cheng Ziyi communicate with each other, their brain waves fluctuate sharply, which is beyond the known range of brain wave activity.
"There's a result." After recording with the instrument for a period of time, Zhou qiuchu said, "you go into the field of divine consciousness and test it again."
According to Zhou qiuchu, Chen Hui entered the field of divine knowledge again, and took Cheng Ziyi into the field of divine knowledge. When Chen Hui withdrew from the field of divine knowledge again, Zhou qiuchu was looking at the test results.
"How's it going?" Chen Hui asked immediately.
"When you and Cheng Ziyi communicate with each other, the brain waves fluctuate violently." Zhou qiuchu said the test results: "after you enter the field of consciousness, the fluctuation of brain waves is more intense! Cheng Ziyi's brain wave fluctuation is at the same frequency as you, but it appears one second later than you. "
"It seems that the exchange of ideas, the field of divine consciousness, does have frequency." Chen Hui said with a smile: "it's just in the fluctuation range of brain waves? The frequency is not big enough to be detected by other devices! "
Zhou qiuchu took photos of the test results, sent them back, and said, "your brain wave fluctuations will be compared with your blood abnormal changes!"
Chen Hui nodded silently. After thinking for a while, he said, "now is the scientific detection method. Next, use some unscientific methods!"
"What unscientific method?" Zhou qiuchu doesn't understand of ask a way.
Cheng Ziyi also looks at Chen Hui.
With a smile, Chen Hui went to the steps of the main hall, picked up the bronze tripod, walked back to Zhou qiuchu and Cheng Ziyi, and said, "recently, nothing unusual has happened to me. The only unusual thing is to establish contact with Shangguan Ruyun and Cheng Ziyi."
After a pause, Chen Hui continued: "and the establishment of this connection is based on the medium of magic weapon. The flying sword absorbed my blood and produced some changes. The bronze tripod has not yet. I am going to drop blood to the bronze tripod again, and then take blood samples for testing."
"It works!" Zhou qiuchu thought for a moment and nodded.
Chen Hui took out a silver needle and stabbed his finger. Drop after drop of blood dropped directly into the bronze tripod.
It's still the same as before. Chen Hui's blood drops into the bronze tripod, and is immediately absorbed, leaving no trace of blood.
After dripping more than ten drops of blood, the bronze tripod no longer absorbed Chen Hui's blood, and the last drop of blood left a bloodstain.
"Go to the hospital to draw blood again?" Chen Hui asked at this time.
"No, I've considered that I might need your blood sample." Zhou qiuchu said: "the equipment for saving blood samples has been brought. Just take your blood samples here!"
With these words, Zhou qiuchu took down several boxes from the box goods. These boxes all have the function of cryopreservation. After taking Chen Hui's blood samples, Zhou qiuchu sealed two test tubes containing Chen Hui's blood samples, put them into the cryopreservation box, and gave them to the staff who opened the box goods and asked them to send them back immediately.
When these staff left, they were driving Zhou qiuchu's car. The van equipment car was left here. At present, it is in the stage of in-depth research. Maybe it will need to be tested again when, and the equipment may be used again.
At this time, Zhou qiuchu took the bronze tripod from Chen Hui, inspected it carefully, and said, "why hasn't there been any change?"
Chen Hui dropped more than ten drops of blood this time until the bronze tripod was no longer absorbed. However, except for Chen Hui's blood, the bronze tripod had no change.
Zhou qiuchu's question is just a question of doubt. She knows it very well and can't get any answer.
Chen Hui and Cheng Ziyi can't answer Zhou qiuchu's question. They don't know why, and they can't even guess.
"Wait for the result!" Chen Hui smiles and says, "I still trust the experts in your department."
"It's no use not believing it. They're at the forefront of technology." Zhou qiuchu took a look at Chen Hui, looked down at the bronze tripod in his hand, and said, "what they can't get results is something that science can't explain. The progress of science and technology is still too slow."
