"Yes, switch!"

Zhang Fan finally decided to try other treatment options provided by the "system". Although he doesn't trust this so-called "system" too much, after such a long time, he probably knows that this "system" doesn't seem to have any ill will towards him. At the very least, the "system" would never rush to take over control of his body without his consent. From this point of view, this "system" is quite disciplined.

"Ding."

"Signs of rheumatoid arthritis were found, severity of illness F. Non-optimal treatment regimen: Grade E drug 'Wet Powder', requiring Grade 1 drug refining. Is it time to get into learning? ”

"Uh, and you're going to get into learning, what's that?"

When Zhang Fan heard this, he couldn't help but be stunned. However, out of interest in this "system", he hesitated for a while and finally chose to enter.

"Yes, let's get in."

"Whoosh!"

Zhang Fan felt to himself that a black hole suddenly appeared in his mind, and the black hole seemed to exude infinite power, so with a "whoosh", his self-consciousness was instantly sucked into the black hole.

"No, where is this?"

Half a minute later, Zhang Fan was shocked to find that he had actually appeared in a huge room.

Moreover, this room is also full of glass flasks, glass test tubes, glass droppers, and other electron microscopes, liquid nitrogen tanks, centrifuges, etc.

In fact, he recognized most of these utensils and instruments, but he did not know what they were used for. Could it be that this is a laboratory? However, if this is a laboratory, it is too big! Moreover, there are too many instruments.

"It's a virtual lab."

And the "system" quickly told him the answer, this is indeed a laboratory, but it is a so-called virtual laboratory.

Virtual labs?

This Zhang Fan has really never heard of the laboratory, in fact, he used to see it often when he was still studying in college in City B. Because, he studied at a medical university, necessary experiments and surgeries, which were often done. It's just that it was four or five years ago, and now seeing such a laboratory again, Zhang Fan feels a little unfamiliar.

What's more, this laboratory is not an ordinary laboratory, but a virtual laboratory, Zhang Fan really can't figure out what this virtual laboratory is, and what does it have to do with his sudden appearance here?

"The virtual laboratory is a virtual reality provided by the 'system' for the host's consciousness. In this virtual reality, the host can carry out all the experimental activities that can be carried out in the real laboratory. ”

Perhaps sensing Zhang Fan's incomprehension, the "system" quickly explained after a short pause.

"What? Virtual reality? That's not true, is it? ”

Zhang Fan couldn't believe what his ears heard, such a thing as virtual reality really exists?

In fact, Zhang Fan's understanding of virtual reality is also at a relatively superficial level. He probably just knows that the so-called virtual reality generally refers to the use of computer simulation technology to generate a three-dimensional virtual world, which can provide users with visual, auditory, and tactile simulations like in the real world, and users can interact with things in this space, move with their own will, and have a sense of integration and participation.

However, this is a relatively sci-fi thing, and the concept is there, but according to the scientific and technological level of this era, it is far from being practical. Moreover, according to Zhang Fan's own understanding, when working in the general virtual reality, it is also necessary to use computers and other special hardware equipment (such as imaging helmets, 3D sound, force feedback game devices, etc.) and information software to simulate the three-dimensional space environment, so that users can interact with computers in this virtual world.

However, how can the virtual reality created by this so-called "system" not need to be like this? Moreover, it was just a "whoosh", and then he was transported to this virtual laboratory without warning.

"Of course it's true. Virtual technology is one of the hallmarks of the 22nd century. ”

"As the most advanced technology integration in the 23rd century, this system will naturally include virtual technology. Now, if the host has no objection, whether to enter the learning process of level 1 drug purification. ”

"Ugh. Are you the most technologically integrated of the 23rd century? That's where you come from? ”

Zhang Fan "heard the words", couldn't help but be stunned, and then said to himself. This "system", in fact, has been in his mind for a long time. However, this was the first time he had heard of its origin.

Of course, he didn't believe 100% what the "system" said, because what it said was too much sci-fi. However, although he did not believe it 100%, Zhang Fan was already slowly inclined to choose to believe it. Because, other than that, it was really difficult for him to explain what was happening to him.

Especially after today's virtual laboratory appeared in front of his eyes, this proves that the origin of this "system" is extraordinary, otherwise, it would not have demonstrated the ability to go so far beyond the level of science and technology in this era.

However, at this time, he would not really be in the learning process of Level 1 drug purification. Because he hadn't forgotten how inappropriate the timing of his entry into this virtual lab was.

You know, just a few minutes ago, he was still sitting in the lobby of the rejuvenation pharmacy to see patients, and with such a "whoosh", his consciousness traveled to the so-called virtual laboratory? In this way, what should I do with the body that is still left in the rejuvenation pharmacy, is it possible that I have already fallen asleep?

"Don't go in yet. I would like to ask, what exactly is that 'dampness dissipation'? ”

Although he couldn't enter the so-called learning process to study, although he also thought that his body that was still in the rejuvenation pharmacy was likely to have fallen, but after all, he was more interested in this so-called 23rd century's highest technology integration, so before he quit, Zhang Fan couldn't help but ask.

So, the "system" quickly introduced him.

"'Dehumidification' is a special drug for the treatment of mild rheumatoid arthritis in the mid-21st century."

"Rheumatoid arthritis is one of the stubborn diseases of the century in the 20th century, but in the 21st century, there has been a breakthrough in the treatment of rheumatoid arthritis, that is, the 'dampness dissipation' that appeared in the middle of the 21st century."

"'Xiao Shui San' is a special medicine extracted from the ingredients of traditional Chinese medicine, which combines the principles of traditional Chinese medicine and Western medicine, and has been clinically proven to have a very good effect on mild rheumatoid arthritis."

"In general, rheumatoid arthritis of grade E and below can achieve a complete cure of 99% after three courses of basic drug treatment; As for rheumatoid arthritis of grade D and above, although it is not completely curative, it has a very effective effect on relieving symptoms such as pain, redness and swelling at the onset of the disease......

In the end, Zhang Fan had to stay in the virtual lab for about ten more minutes.

It's not that he has forgotten that the body in the rejuvenation pharmacy doesn't know what is going on, but the so-called "dehumidification" information explained by the "system" is so attractive that he can't help but want to continue listening for a while, so he was forced to delay for a while.

However, it is precisely because of this period of delay that he feels that "this trip is in vain".

Because, first of all, the first takeaway is that he finally learned the origin of this "system". According to its own introduction, he is actually from the 23rd century high-tech, but I don't know why he is here, and why he lives in Zhang Fan's mind. This may be related to the memory that Zhang Fan lost in the Middle East. However, he can't verify this matter for the time being, so he can only put it down.

Secondly, the news of the so-called "dampness dissipation" is really exciting. If that's true, that's great. At the very least, it will be a boon for hundreds of millions of rheumatoid arthritis patients around the world. For example, the middle-aged eldest sister who came to him just now is likely to benefit from this.

Of course, 90 percent of this should be true. Otherwise, the "system" would not be so conclusive, and its function would be explained in such detail.

Although Zhang Fan does not have any lofty ideals to save the common people, he is still very happy to see that hundreds of millions of rheumatoid arthritis patients in the world have been relieved of their pain.

This is actually his most primitive and direct feeling as a doctor.

In fact, the reason why he applied for medical university in the first place was not necessarily that he did not have the ambition to treat diseases and save people. It's just that after he enlisted in the army and finally rolled around in the barracks for several years, such ambitions have not been remembered for a long time.

Of course, this is not to say that being a soldier is any worse than being a doctor. In fact, in terms of the size of his contribution, Zhang Fan's past few years in the military camp and abroad are probably not at all imaginable by an ordinary doctor.

"Ding!"

"Host willing to exit virtual reality detected!"

"Ready to quit!"

"Exiting!"

"Ding."

"Exit complete!"
