At this time, outside the main hall, the five major and Wu Er dragged four infected people who were tied up by five flowers and walked in, just two men and two women, although these four infected people have been tied up and sturdy, only their heads are exposed, but they are still viciously opening their mouths wide, making it look like I want to bite everyone present.

Wu Dawu Er casually threw the four infected people in front of Li Lingyu and a group of doctors, and all the doctors present flocked to it, and after bringing anti-infection clothes, they gathered around the four infected people, some squatted down to look carefully, some leaned over with their noses to smell the breath, some took out silver needles to prick them here and there, and some boldly took iron clips to open the mouths of the infected people, looking at the mouths of the infected people full of blood and foul smell, and some also took out sharp knives to open a small hole in the head of one of the infected people, and the small hole gushed blood, and soon the infected person did not move, and the doctors showed very excited expressions on their faces, As if these four infected people are not dangerous humans infected with demonic diseases, but toys that have been liked for a long time and are finally in their hands now, but they are also sad that this group of doctors will be like this, after all, this is the first time they can safely observe the infected people up close, as a doctor, they all want to be the first to develop a prescription for the treatment of demonic diseases, so that they will be famous through the ages, and become a famous doctor admired by thousands of people.

The doctors tossed the four infected people for a long time, and they all made them look a little dying, and before they stopped, Zhu Xuanchen couldn't wait any longer, so he asked: "How about all of them stop? Is it still possible for these infected people to return to normal? You still draw conclusions first, and then study them slowly, the group of demonic creatures and infected people outside will not wait for you for so long." ”

After the doctors were stopped by Zhu Xuanchen, they didn't answer first, but stood aside and discussed in a whisper, and after a while, the doctors stopped discussing in a whisper, Li Lingyu stood up, and said with a sad face: "These people who are infected with demonic diseases, I'm afraid it will be difficult to recover, we use silver needles to stimulate their various acupuncture points, they don't have some reactions that normal people should have, and they have no brains in their heads, and all of them have turned into blood, as if these bloods are controlling them, so ...... Even if we come up with a cure and cure them, it will not be possible to restore them. ”

"Then how can you say that there is no cure for this demonic disease? There is no need to study any prescriptions? You can only rely on the method of killing one by one to stop the spread of the disease?" Zhu Xuanchen asked in surprise.

Li Lingyu sighed and said: "Alas~ This can only be the case, what our doctors can do may only be to develop some drugs that can resist being infected or can delay the time of disease mutation, and finding the source of the virus and eliminating all demonic creatures can only rely on cultivators." ”

"Then we can only clear out these demonic creatures and infectors outside first, and then I will set up a phantom array to protect this place from being besieged by demonic creatures and inpatients, and then you just need to wait here for the support of Chaos City." Zhu Xuanchen said slowly.

After everyone nodded in agreement, Zhu Xuanchen and the Wu brothers immediately flew out and began to clean up the large number of demonic creatures and infectors surrounding the palace, fortunately, the palace is the main living area of mortals, and no demon beasts will live here, so the demonic creatures outside the palace are just some ordinary animals, and there are no demon beasts, otherwise this palace is estimated to not last now.

Three days later, it took two days for Zhu Xuanchen and the three of them to completely clear out all the demonic creatures and infectors outside the palace, and it took another day to arrange a simple phantom array, so that these infectors and demonic creatures could not see the existence of the palace, and they would not come to attack here.

Zhu Xuanchen took out a piece of white paper full of words and strange symbols and handed it to Wu Da, and then said: "This is the layout and repair method of the phantom array, with this piece of paper, you can maintain this formation without me and protect this place." ”

"Where are you going?" asked Wu Da suspiciously, taking the paper.

"I'm going to investigate the source of the demon disease first, now the demon disease is spreading too fast, acting earlier can prevent more people from being infected with the demon disease, and when the people after the Chaos City come, you can tell them, I'm going to the west, that is where the demon disease began to spread, maybe the source of the demon disease can be found over there, you just wait here for the next instructions from the Chaos City, I'll take the first step." Zhu Xuanchen explained.

"Alright then, be careful, and come back as soon as anything happens. Wu Da said sincerely.

After Zhu Xuanchen nodded, he flew out of the palace alone and flew in the direction of the west.

There are five rivers in the country, so it is named Gokawa Country, and the source of these five rivers is located in Mt. Aomine, and the snow accumulated on the top of Mt. Aomine for many years melts and diverts to form these five rivers.

After Zhu Xuanchen set off from the palace, he has been flying westward along a river near the palace, along the way he saw a lot of corpses floating in the river, and the river water has turned light red, if the people who are downstream of this river drink the water in this river, they will definitely be infected with demonic diseases, but he can't help it, the number of corpses is too much, not only there are corpses in this river, but there are also other rivers, and even some pools, There were all in the lake, and he was very strange at first, but until he saw several times that people or animals infected with demonic diseases would pounce on the place where there was water when they felt like they were about to starve to death, and then they drank water frantically, and finally they would suddenly die when they drank, and the blood in their bodies would come out of their bodies by itself when they died, and then go to the rivers, and these infected people who died by themselves did not have any scars on their bodies, and the blood came out of their eyes, mouths and noses.

This made Zhu Xuanchen feel very strange, so that he had some vague thoughts, he suspected that these blood seemed to be alive, these infectious and demonic creatures, as if they were their hosts, after infecting them, they instinctively controlled the host to attack any living creatures, after the host did not eat for a long time, and the end of life was about to end, it would make the host feel very thirsty, and then the host would naturally go to find water, and after coming into contact with water, the blood would leave the host that was already certain to die, leaving an empty shell.

Zhu Xuanchen's own idea is inconceivable in Zhu Xuanchen's own opinion, how can blood have life? Although life needs to rely on blood, blood cannot produce life and wisdom? Isn't this some kind of secret technique? Some behaviors that give blood life and instinct?

Thinking of this, Zhu Xuanchen didn't dare to think about it anymore, even if someone knew this kind of secret technique, but how many people would be killed like this, what was the benefit? He really didn't dare to think about it, and he couldn't figure it out, there were too many things that he didn't understand now, and he could only start from the source of the disease now.
