After Liu Huaidong said goodbye to his four wives and returned to the Chinese Medical Hall, it was no surprise that he worked overtime all day and night.

Fortunately, most of the people in the Chinese Medical Hall have some cultivation, and no matter how bad they are, they are all for the sake of health, and they have learned some cultivation from other colleagues, and they all have the cultivation of the pinnacle of foundation building at the very least.

Of course, Wang Yiran is an exception.

However, even Wang Yiran, an ordinary person, stayed up late with everyone during this time, and his spirit was a little sluggish after a few days.

If it weren't for Liu Huaidong's infusion of herb mana for Wang Yiran every few hours, I'm afraid that after three days, Wang Yiran would have been in shock even if he hadn't died suddenly.

The hall masters are all leading by example, what reason do their masters with cultivation have to be lazy?

Therefore, since the headquarters of the National Medical Hall, it can be said that it has been lit up 24 hours a day in the true sense, even if it is a newcomer who has just joined, there is no leisure for a moment.

In the past few days, through the unremitting efforts of all the members of the National Medical Hall, the vaccine, which integrates the two ideas of Liu Huaidong and Zhang Wenliang, has also been developed in more than 30 different versions.

Two of the versions were from Chen Guodong, three were from Liu Huaidong, and even Wang Yiran developed a version of the vaccine with the professional equipment of the Chinese Medical Hall, which is ahead of any medical institution in the country.

To be honest, in fact, everyone is most optimistic about these six versions of the vaccine, and most people firmly believe in their hearts that if this batch of vaccines is determined to have a successful version after testing, it will definitely come from these six versions.

There is no way, after all, the three people who developed these six vaccines are equivalent to three mountains that carry half the sky in the National Medical Hall, and countless people can not reach them.

Except for these three bigwigs, everyone else is a research team of three to five people, and these days, some groups have developed one or two versions of the vaccine, while others have no research results.

But for those groups that have no results, Wang Yiran didn't reprimand them much, after all, she herself knew that time was indeed too tight......

"Okay, everyone has worked hard these days, now that the first batch of samples has been released, then everyone can take a break, label this batch of samples with your various groups, collect them uniformly, and take them to the laboratory for testing. ”

Hearing that they could finally rest, everyone, including Liu Huaidong, breathed a sigh of relief in their hearts.

However, other people's rest, it is really rest, Liu Huaidong and Chen Guodong and other core members are destined to not live such an easy life.

Their so-called rest is just that they don't have to focus on the research and development of new vaccines, and as for the testing of more than 30 sets of samples, the National Medical Hall did not set up the position of intern, so it naturally fell on them.

Several core elites didn't need to communicate at all, and without waiting for Wang Yiran to assign them tasks, they spontaneously went to collect the samples developed by other groups, and then silently walked to the laboratory.

Wang Yiran is naturally at the forefront, but what is commendable is that other people are also behind several elite bigwigs.

One of the labs is made entirely of clear tempered glass, though they may not be able to get in.

However, it can also follow the detection process and results of more than 30 groups of samples in real time.

This is the initiative of everyone to give up the hard-won opportunity to rest, and it is clear that everyone present cares very much about the test results of this batch of vaccine samples.

After several people entered the laboratory, they exchanged glances with each other, and then they dispersed, using different equipment and different methods to test the effect of the more than 30 groups of vaccine samples in batches.

Chen Guodong and Li Guoyong each used a test bench, and the initial detection link was the most direct and stupid method, drip the components of the vaccine sample into a container containing the origin of the virus, and then observe the reaction after the fusion of the two through a microscope.

Wang Yiran came to his own exclusive test bench and did much the same thing as others, but the medical equipment on this test bench was a style principle that the outside world had never heard of.

Some of the equipment looks simple and simple, like an antique from the seventies, and some of the equipment is full of technology just by looking at it.

These medical devices are actually developed and designed by Wang Yiran according to some of his own habits.

Every detail is from Wang Yiran's hands, and the final manufacturing and production is responsible for the top scientific research team in China.

As for Liu Huaidong's side, the way to test vaccine samples is much simpler and crude.

Several people divided it equally, and Liu Huaidong was in charge of the first testing procedure, there were five groups of vaccine samples, and Liu Huaidong's way of testing them was to directly use the gas machine to pull the five test tubes in the air.

In the last five test tubes, a small part of the vaccine samples miraculously flew out of the test tubes on their own, and then Liu Huaidong used his own magic power to conjure up a high-concentration of the origin of the agoutine virus, and then the virus was divided into five in mid-air.

Five groups of dark purple virus origins and five groups of pale cyan vaccine samples fused in the air, and then each showed a different reaction.

Two of the vaccine samples were completely devoured and wiped out by the source of the virus before they barely lasted for three seconds, and the whole was assimilated into a dark purple color.

The other three groups of vaccine samples have been fighting against the agoutus virus for a long time, but they were all devoured and killed by the virus.

The only difference is that the three groups of vaccine samples were assimilated by the virus for a long and short time, and the longest group only lasted for two minutes.

Looking at the five clouds of dark purple liquid suspended in front of him, Liu Huaidong couldn't help but sigh gloomily, and waved his hand to directly disperse the origin of those viruses.

"Alas, all five sets of samples on my side failed, and there was no need for a second testing session. ”

After sighing, Liu Huaidong didn't forget to say hello to a few other people, and as for the many members of the Chinese Medicine Hall who were watching the testing process outside, they couldn't help but sigh after seeing Liu Huaidong's results come out so quickly.

No one will doubt whether Liu Huaidong only took such a short time to check whether the inspection was detailed enough, and even on the contrary, everyone believed that among the big guys in the laboratory, no one gave more reliable test results than Liu Huaidong's.

Following Liu Huaidong, the next one reported the test results

It was Chen Guodong, and the five sets of vaccine samples in Chen Guodong's hands also failed without even passing the first testing link.

Followed by Wang Yiran, it is more gratifying that one of the five sets of vaccine samples in Wang Yiran's hand successfully passed the first round of testing.

This means that the sample can successfully kill all viruses when they are placed in the same container as the source of the virus.

However, in the second round of ingredient testing, Wang Yiran found that the combination of the three elements in the vaccine can actually evolve a chronic toxin that is harmful to the human body.

It is absolutely impossible for such a vaccine to be put into mass production, so so far, the only vaccine sample that has passed the first round of testing has also ended in failure.

Looking down at the label on the test tube, Wang Yiran couldn't help but turn his head and smile bitterly at Chen Guodong: "Old Chen, it's the sample you developed." ”

"Well, as expected, the time is really too tight for me to do a few more experiments. ”

The corners of Chen Guodong's mouth also flashed a somewhat bitter smile, and then turned his gaze to Li Guoyong, and another colleague who had not yet reported the results of the examination.

Everyone outside the laboratory also focused on these two people.

A few minutes later, Li Guoyong finished testing the four sets of vaccine samples in his hand, all of which failed.

It's just that when he placed the fifth group of vaccine samples in the same container as the source of the virus, the viscous liquid that fused together quickly turned into a clear pale cyan at a speed visible to the naked eye.

It's just that there are still some insignificant dark purple dots in it, which are also being assimilated by the pale cyan vaccine ingredients.

Seeing this scene, Li Guoyong's eyes couldn't help but light up, "Hall Master, come and see, it's incredible that this group of vaccines can kill all the sources of viruses at such a fast speed!"

In fact, there is no need for him to speak, Wang Yiran, Chen Guodong, and Liu Huaidong and others have long noticed the movements on his side.

At that moment, everyone in the laboratory walked to Li Guoyong's side, and the members of the Chinese Medical Hall who were looking forward to it outside also did not dare to take a breath with bated breath, hoping for a miracle.

"Quick, immediately put into the second round of testing to check the composition of this group of vaccine samples!"

"Yes, yes, yes!"

After Li Guoyong heard Wang Yiran's words, he quickly used a sampler to collect a drop of vaccine sample in that test tube, and then carefully dropped it on a glass slide and placed it under a high-powered microscope.

The picture in the microscope was also projected on a small LCD screen on Li Guoyong's test bench, and everyone could see that the picture displayed on the screen was that the molecules were moving slowly.

As Li Guoyong moved the angle of the microscope observation glass, the look of surprise on the faces of Wang Yiran and others became more and more intense.

"Great, great, the components of the virus only account for less than one thousandth of the samples, and they are still being killed by the vaccine at a very fast speed, and there are no ingredients in this group of vaccine samples that are not conducive to human function, so it can be put into mass production!"

Wang Yiran shouted in surprise while taking the last set of samples that Li Guoyong was in charge of, "Let me see, whose masterpiece is this group of samples?"
