Just when Jiang Cheng was studying how to operate on the three of them, Du Ruoxi called.

"Jiang Cheng, help me figure out a way, my family is missing."

"Don't panic first, I'll contact the officials of Yunguo and use the power of the whole country to find them, you must be calm, don't do anything stupid."

Jiang Cheng was taken aback when he heard it, the former person in charge of country M had already died in Huangquan, so the disappearance at this time may have been done by aliens.

So he immediately put down the materials in his hand and went to the office of the person in charge of Yunguo in person, he wanted to use the power of the official to help find Du Ruoxi's family.

The person in charge of Yunguo used the official to send a message to countries around the world: Professor Du Ruoxi's family had cut off the news with him not long ago and was suspected of being missing. If you find it, you are contributing to the world.

They have already used the help of the world, and there should be news of them soon, Jiang Cheng immediately conveyed the news to Du Ruoxi.

"Thank you, thank you, I really don't know what to do, if they're really gone, what's the use of me living alone?"

From Du Ruoxi's tone, he was already disheartened at this time, but both of them had a heavy responsibility, and now there was no better way than to wait for the result with peace of mind.

After more than ten minutes of comfort from Jiang Cheng, Du Ruoxi slowly calmed down.

"You're right, we are people who dedicate ourselves to global scientific research, and we have been ready for everything since we first stepped into this career, and now that the whole world is helping, you and I should not stop the task at hand."

Jiang Cheng also had to operate on three people to take out the special substances in their bodies.

If the person in charge of Yunguo gets the news from the international side, he will notify Jiang Cheng as soon as possible, and Jiang Cheng will also inform Du Ruoxi of the news as soon as possible, no matter how tired he is.

Now Jiang Cheng is in trouble with the three of them doing surgery.

The leader of the scientific research team sat next to Jiang Cheng.

He was wearing headphones, and when he saw Jiang Cheng thoughtfully, he kicked his feet, and the whole person was dragged by the stool and moved to Jiang Cheng's side.

However, because the earphone cable is not long enough, the contact is not good, and the frequency of noise is extremely high.

"What is Professor Jiang thinking?"

When he heard these noises, Jiang Cheng involuntarily covered his ears, then turned his head and saw three people with hideous faces and expressions that looked very painful.

Seeing that the situation was not right, Jiang Cheng immediately ran over, put his hands on a person's shoulders, and shook slightly.

"What's wrong with you? What's wrong with a few of you? Wake up, wake up, wake up. ”

As the noise stopped, the three of them slowly returned to normal, and Jiang Cheng realized that although the special substances in the bodies of several people were not enough for the alien civilization to control them.

However, if they are stimulated and influenced by external frequencies, special substances in the body will also change, so that they will be uncontrolled and show the symptoms just now.

The three of them have come to their senses.

One of them shook his arm and covered his forehead.

"It was like being electrocuted just now, and my whole body felt numb, and we didn't know what was going on."

Jiang Cheng thought about it for a while, and immediately had an idea.

"Hurry up and order the operation, I already know how to remove the special substance from their body."

It turns out that these substances react under the influence of external frequencies, and as long as the frequency stimulation is used to transfer all their substances to one place, they can be removed by surgery.

This is thanks to the team leader just now, if it weren't for his unintentional actions, Jiang Cheng would probably have no clue now.

Sure enough, under the stimulation of frequency, not all of them moved.

All the substances in the bodies of the three people were taken out by Jiang Cheng.

Who knew that after a comprehensive examination of the three people to ensure that there were no special substances in their bodies, Jiang Cheng let the three of them leave, and he also had to help inform the political party of country M.

"I have to have a check-up every day when I go back, and if there is anything unusual, I have to come to the institute to find me."

The three of them hurriedly thanked them, if it weren't for Jiang Cheng's help, the three of them would probably be locked up in the quarantine area, obviously there was no harm to society and the country, but they would still be treated like aliens.

Jiang Cheng looked at the special substance in the test tube, how can this kind of substance, which is sometimes liquid and sometimes solid, control people's minds and bodies?

In order to prove his conjecture, Jiang Cheng came to the frequency change meter with a test tube, he put the test tube against the instrument, and then kept increasing the frequency.

Look at the change in the state of the special substance in the test tube.

Jiang Cheng seemed to understand a truth, if the frequency was enhanced, this special substance would change from a solid state to a liquid state, so that they would shuttle freely through the human body.

Although this is not enough for a person to control his mind and body, what kind of effect does it have on smaller mammals from a different perspective?

While thinking about it, Jiang Cheng came to the biological research center.

Although it was aimless, he knew that there would be research experiments he needed.

Jiang Cheng walked up to the mouse and stopped.

After mentally calculating, he already knew how much weight could control the guinea pig.

So from the utensils next to him, he took a set of syringes and took the mouse to the frequency change meter.

At this time, most of the special substances in the hands have become solid, and the inertia of the two states changes with each other, and a certain amount of time buffering is still required.

Jiang Cheng will increase the frequency, and the mouse will run around in the cage with wide eyes, as if he has a premonition that he will be treated as an experiment by Jiang Cheng.

At this time, the special substance in the test tube had already turned into a liquid state, Jiang Cheng seized the time to draw a certain dose, and immediately turned off the instrument.

The mouse has returned to normal, and Jiang Cheng is eager to use a needle to deliver a special substance to the mouse's body, and then he has to see the effect.

At this time, there was nothing abnormal about the mouse, and the special substances remaining in the city management had become solid, and Jiang Cheng speculated that the special substances in the guinea pig's body had also become solid.

But at this time, Jiang Cheng didn't know how to control the behavior of the guinea pig.

His brain was running rapidly, thinking of the signal sent by the alien civilization some time ago, even the technician said that there was no problem with the frequency, but he instinctively told himself.

That incident at that time must have a close relationship with the present, so Jiang Cheng decided to use the signal to test whether it could control the effect of the mice.

As he expected, the signal really controlled the behavior of the guinea pig.
