Zhen Fei is not idle, he is really busy.

After Qin Ying left, there were still three girls left in the refining machine, and they needed help, Leng Xiao's pharmaceutical factory was not perfect, and the clinical trials of drugs needed to record data at all times, of course, all of this has been tracked by special personnel, but Zhen Fei needs to get data from the tracking records of different patients immediately, and then make a reference for the next step of development.

These things are all academic studies that Tang Xiaoxiao doesn't understand at all, they are very complicated, and they require a cautious attitude, Zhen Fei is very worried about letting others do it, he has to take it into his own hands, if the drug has side effects, it will cause devastating results.

Zhen Fei, who is dedicated to treating diseases and saving people, will never allow such a situation to occur. His patient Chen Feifei is an experimental product, and it is also an experimental product after the maturity of the drug, she is a victim of drugs herself, and her body is on the verge of collapse, she is an excellent candidate for experimental drugs, Zhen Fei also has to pay attention to the spread of Chen Feifei's HIV, so he is really busy, Tang Xiaoxiao can't think of how difficult Zhen Fei's work is.

After returning to Haoting, Zhen Fei immediately entered the laboratory, and Zhou Xiaocong and Nie Qingye, who had just turned from students to disciples, did not even go home, they worked in the laboratory without feeling. Seeing Zhen Fei coming back, they cheered together and said, "Master, you come to see this embryo experiment, there is always no movement, why is this?" ”

Zhen Fei walked over and took a look, and asked in surprise, "What kind of virus culture is this?" He could tell at a glance that this was a viral research experiment, not a new drug research.

"It's the culture of the AIDS bacteria." Zhou Xiaocong whispered, and angrily pouted at Nie Qingye, meaning that you come forward to explain. For Zhen Fei, Nie Qingye was just as afraid, shrugged his shoulders, spread his hands, and expressed helplessness.

Zhen Fei carefully observed the activity of the germs, and then said to Zhou Xiaocong: "This experiment is entrusted to you to be in charge, such germs are absolutely not allowed to spread, once a breakthrough result is achieved, explain the situation to me immediately." ”

"Okay, Master, please rest assured, Master was a doctor when I was in China, and I know how to protect the research results."

"Not only the research results, your vision is still too narrow, any research in medicine, will bring a completely different medical revolution, you must keep in mind that the results are definitely not anyone's efforts, but everyone's, if anyone wants to monopolize the results, it must be a tragic end."

Because Zhen Fei's thinking jumps too much, Zhou Xiaocong doesn't understand very well, standing on different positions, he must see from different angles.

Zhen Fei stood in the highest position, mastering the operation and changes of the overall situation, Zhou Xiaocong was just standing on a personal point of view, of course he would not understand Master's mind, and later after Zhou Xiaocong told Fang Yuanyuan, Fang Yuanyuan said a word, which opened the doubts in Zhou Xiaocong's heart, Fang Yuanyuan said: "What Master wants is the health of all mankind and the development of civilization, he is a great person, you just need scientific research results, of course you will not understand Master's mind." ”

Only then did Zhou Xiaocong realize that all the efforts they were making now were just one of the many chess pieces laid by the master, and they were not a special case.

What worried Zhen Fei the most was Qin Ying who entered the underworld to exchange materials, until after the fifteenth day of the first lunar month, Qin Ying still had no news, and there was no direct contact between the world and the underworld, so he couldn't sit still anymore, asked Qu Jinlin for leave, and decided to go to the underworld.

However, the pharmaceutical factory's several new drug improvement plans reached a very critical time, and the departure time was delayed again and again, until several technical difficulties were overcome, and it was already around March 3, and the departure time was delayed for three months.

Qiao Huizi is now at ease, and asks to enter the underworld with Zhen Fei to open his eyes, Zhen Fei and Qiao Huizi are already husband and wife, and their relationship is very good.

If you turn to the western frontier, not only is the road far away, but it will take time to fly over the desert after arriving in the underworld, the teleportation boots are still in the hands of the little white wolf, and Zhen Fei only has a flying horse by his side.

Due to the rush of time, Zhen Fei chose a crossroads in Shanghai to enter the underworld.

It was early in the morning in the underworld, and Zhen Fei, who had just gained a foothold, heard a loud shout: "The demons in the world are gone, eat me with a knife." ”

Then the wind was fierce, and a snowy big knife was slashed down on the head and face, and directly took Zhen Fei's head. Zhen Fei's mind moved, and he took out the Sky Shaking Bow that had advanced to a primary artifact.

"When-" There was a loud sound, and the giant big knife in the hand of the guard guarding the entrance was blocked, and after touching the blue and red sky-shaking bow, it made a deafening sound, Qiao Huizi was a little sluggish, she was still entering the underworld for the first time, and she was not very suitable for the environment here, just like seasickness, and her brain was a little confused.

Zhen Fei grabbed Qiao Huizi's arm, turned back to the guard and shouted, "I don't want to be your enemy, it's better for you to retreat quickly." ”

"Where is the duty, can you allow cowardice? The thief left and continued to eat me. ”

The guards are still entangled, Zhen Fei is impatient, and in a moment of thought, he pulled out the sky-shaking bow, and swished out three feather arrows, the sky-shaking bow has been upgraded to an artifact, and the power has increased dozens of times, the feather arrow made of mana is no longer a brilliance, but as bright as a meteor, the first feather arrow forced the guard to take a step back, dodging and not falling, the second arrow shot into the guard's thigh like a meteor, and shot that leg through, the third arrow followed closely, Zhen Fei's heart moved, and he saw that the guard was injured, The third arrow was temporarily canceled and the pursuit was no longer continued.

It was only then that I heard the rumbling sound of the feather arrows, like ten thousand horses galloping, thrilling.

Zhen Fei's body shook slightly, and he walked in the air, and in a blink of an eye, he pulled the injured and bleeding guards away from a distance of hundreds of meters, and after sacrificing Pegasus, he added coins, and Pegasus gained momentum, and his four hooves rose into the air, his wings stirred, and he hissed and flew away from the entrance happily.

Zhen Fei was near here when he first came in, and met Princess Huanhua, and this time he entered the old place as a revisit. I was overwhelmed with emotion and sighing, every time I entered the underworld, the feeling in Zhen Fei's heart was completely different.

His constant adventures have greatly increased his power, and his knowledge of the monk has also improved.

Looking down from the top of Pegasus, the mountains and rivers were in sight one by one, and Qiao Huizi, who had calmed down, couldn't stop talking, and her heart swayed. Many trees are species that cannot be seen in the world, the underworld has a very primitive taste, has never been developed, most places can not even see decent roads, as far as the eye can see, thousands of miles are uninhabited, many animals run in groups to forage, some of them roared and roared at the flying horses in mid-air, indicating that they were very angry.

"It's really primitive, a real wild place." Qiao Huizi let out a sigh of emotion and said, tightening Zhen Fei's arm even more.

"This is the underworld, there is no gloomy atmosphere, it still looks like it is bright and clear, but there will be a kind of pressure that is not in the world, the atmospheric pressure of the underworld is completely different from the world, and the people who live here advocate Taoism, spells, and do not know anything about science and technology, they are really two completely different worlds, everyone pursues the art of immortality, generally speaking, people who die at the end of their lives can live for thousands of years, there are many elves, and the thousand-year-old monster is no longer a legend." Zhen Fei once again gave Qiao Huizi a brief introduction to everything in the underworld, so that she could enter the role as soon as possible and be familiar with the environment here.

"You should be a mage with profound mana, ordinary people don't dare to provoke you, right?" The psychology of admiring heroes made Qiao Huizi admire Zhen Fei very much.

"Wrong, every time I come to the underworld, I win with an artifact, the masters here are like clouds, and the ordinary mages are more powerful than us."

"There's someone there." Qiao Huizi said, pointing to the hillside below.

Staring at it, on the slope of the strange rocks, there were figures swaying, all of them were monks flying in the sky, and more than a dozen people surrounded one of the men with half-black and half-white hair. Without warning, the two sides fought.

Zhen Fei drove the Pegasus and stopped in mid-air to watch, and said in surprise: "The person who was trapped in the middle turned out to be Zhao Qinzhong. ”

"Is it your friend?" Qiao Huizi was very surprised, she didn't expect Zhen Fei to have acquaintances.

Shaking his head, Zhen Fei said, "Have you forgotten that I once talked about my wanted?" I was regarded as an enemy by the Zhongnan faction and the Xian Zhen Pavilion, and the little white wolf was also wanted, this Zhao Qinzhong was also one of them, he was a traitor to the Liuli faction, as for how he betrayed, but there was no way to know, I only saw his portrait, but I didn't expect to see him for more than half a year, his hair turned gray, it seems that he must have lived a very hard life during this time, and he looks a lot older. ”

"Yikes! You see, that Zhao Qinzhong seems to have been injured, and he fled. Qiao Huizi pointed down in surprise and shouted.

"Let's go, the people here are all unreasonable people, and they will not be harmed by the pond fish." Zhen Fei was about to leave, but found that Zhao Qinzhong was flying in the direction of Pegasus, and kept waving for help, looking very anxious.

Do you want to save a strange passerby? Zhen Fei's heart was very hesitant, he was not afraid of those pursuers, but he didn't know if this Zhao Qinzhong was a good person or a bad person. At the moment of hesitation, Zhao Qinzhong was already approaching Pegasus, and said anxiously: "This friend is invited, please take this child in, I will continue to lead away the pursuers, and the great kindness is unforgettable." ”

After finishing speaking, Zhao Qinzhong took out a child who was only three or four years old and threw it at Zhen Fei.

Subconsciously stretched out his hand, Zhen Fei took the child in his hand, and saw that Zhao Qinzhong was still concerned about the child's safety at a critical moment, his heart moved, and asked, "Is this your child?" ”

Zhao Qinzhong said anxiously: "I don't know each other, I inadvertently saved this child and offended those people, these things have nothing to do with Your Excellency, it's better to leave quickly, so as not to be implicated." ”
