After two days and one night, the four of them returned to the college and sent them directly to the college medical hall for treatment. Today is Dr. Liu on duty, after they informed Dr. Liu of the situation, and also told her their speculation, Dr. Liu carefully examined, and then asked them to go back to rest first, and she will call other researchers and doctors for a consultation later.

Dr. Liu reassured them that the sea would be safe here, and that she would stabilize the state of the sea first and not let it deteriorate again. Finally, he told them to go back and have a good rest, and they might be summoned tomorrow because of the problem of the demon clan in the fairy forest.

Hao Yun was particularly remorseful, if he hadn't been stupid enough to go back to get the demon pill, he wouldn't have had such a big incident, after all, the sea had caused the Spirit Lake to dry up in order to save him, and if something happened to the sea, he would never forgive himself in this life.

Quartz Sword flew all the way with flying swordsmanship, and he was tired, so he had already gone back to the dormitory to rest. Fei Fei said that she could accompany the sea, but she was also resolutely persuaded by Dr. Liu, saying that there were special nurses in the hospital to take care of her, and she did not need her help. Hao Yun stayed outside the hospital for a while, and then went back to the dormitory without any way.

Soon, some researchers came to the research institute, and other doctors came over to check the body of the sea, and finally came to the conclusion that like the doctors in Demon Forest City, the spirit lake was exhausted, but because it was the spiritual power of the water system, the traditional pills and methods were not very applicable, and in the end, Doctor Liu came up with a solution, which was to refine the spirit pill with the water demon pill, which should be able to solve the problem of replenishing the water spiritual liquid in the spirit lake.

The refining method of the elixir itself is not difficult, and the normal main material is spirit crystal, but at least it is a medium-grade spirit crystal, and the number of spirit crystals is quite large. So theoretically, it can be refined with a water-based mid-grade spirit crystal, but at present, I haven't found a water spirit crystal mine, let alone a water-based mid-grade spirit crystal, so now it is most likely to be a water-based demon pill, but at least a demon pill equivalent to a water-based demon beast in the late stage of Jindan is needed, and if it is in the middle of Jindan, more than ten pieces are needed, otherwise I am afraid that the medicinal power of the refining elixir will not be enough, and the Jindan will not be suitable at all in the early stage. There is no way to do this, although the sea is only in the late stage of foundation building, but to solve his problem, he can only use raw materials with more powerful energy, after all, there will be energy loss in the process of making the elixir, and it will not be 100% absorbed when taking it, and the spirit lake is depleted, it is not a simple replenishment of spiritual liquid. When a cultivator encounters energy exhaustion, the body will have a protective stress response, and at this time, a coma will appear, and the divine consciousness will form a membrane to protect the head, at this time, unless he wakes up, once he forcibly stimulates it, the consequences are unimaginable.

Early the next morning, Hao Yun, Quartz Jian and Fei Fei ran to the medical hall, but the medical hall had not yet opened, and the nurse who guarded the door did not let them go in to see the sea. And let them go to see the sea first, and then go to the academy to find Pan Shi, Pan Shi and they want to understand the problem of demons.

After knowing the way, Hao Yun and their suspense were put down, and they ran to the ward together to see that the current situation of the sea was stable, so the three of them went to the college building to find Master Pan.

In fact, Quartz Sword and Fei Fei didn't see the demon either, because they considered the state of the sea at that time, so they didn't have the opportunity to ask Hao Yun carefully, what happened? What is this demon like? Is it female or male?

Since the demon clan was driven to the place of exile, the spirit world human world has not seen a demon for many years, and everyone is more curious.

Hao Yun couldn't answer these questions, because at that time, he also used mirror techniques to see, and he didn't see anything clearly, but he felt that he was a powerful demon, so he hurriedly ran for his life.

Now when I pause and think about it carefully, it feels like a dream, and everything happened like lightning. When he came back to his senses, the sea was lying in his arms, and he tried to escape with his escape technique, just wanting to fly to Demon Forest City quickly.

Hao Yun and the others came to Pan Shi's office and carefully explained what happened at that time, Pan Shi was more interested in the fire crystal gun they made, asked a few more questions, and encouraged them to polish this thing well, this fire crystal gun is still very promising, about the loud problem, you can consider adding a silence array, how to add it will achieve the effect, they need to do more experiments. Hao Yun hid the matter of taking the demon pill with a flying sword, and said that he was going to go back to get the demon pill, and when he observed the situation with the mirror technique, he met the demon who was alarmed by the gunshot, and then he was discovered, and he ran into the sea in the process of escaping, and was rescued by the sea, as well as the teleportation technique about the sea, because Hao Yun They didn't know either, so they could only wait for the sea to wake up and then understand.

When asked about the demon appearing in the fairy forest, Hao Yun couldn't say anything, because from beginning to end, Hao Yun never looked at the demon, that is, a glimpse in the mirror.

In fact, the demon also attacked him and fished him out of the ground with his spiritual power, but because he didn't want to expose his ability to escape from the earth, it would be too laborious to explain it. Besides, he didn't think that he could infer anything from the spiritual power.

The more he thought back to the scene at that time, the more frightened he became, this battle in the spirit realm was simply terrifying, if the realm was relatively different, there was basically no possibility of fighting back. Fly slower than others, attack power is worse than others, attack distance is also short, the range of divine consciousness is also small, completely blind, people want to fight, when they want to fight, you can't think about it, it's even difficult to interfere. Thinking about the scene at that time, the demon didn't plan to kill him all at once, so he had a chance to be rescued by the sea.

Master Pan couldn't ask anything after seeing it, so he told them to go back and work hard to cultivate, and the sea academy would handle it.

At this time, the secretary of Pan's office knocked on the door and came in, saying that Dr. Liu was coming soon, saying that there was an urgent matter, and they asked them not to leave, and she would come over after a while.

Hao Yun and the three of them made eye contact with each other, not sure what was going on, it shouldn't be the sea that had a physical problem, right? When he was nervous, Doctor Liu brought a woman with a mask on her face over.

It turned out that Dr. Liu had received feedback from the cooperative merchants just now, because the current situation in the Linghai was not very good, there were more accidents among cultivators who hunted sea demon beasts during this time, and the merchants had not received the water demon pill for a while, and because what was needed was at least the demon pill in the middle stage of Jindan, which was also more difficult for ordinary cultivators. In fact, it's also very easy to understand.,The demon beast that can reach the infancy stage is basically not a demon beast.,That's a demon.,Of course, it's not that there is no demon beast in the infancy.,But the monster beast born in the infancy stage is very talented.,It's estimated that even the demon who transforms may not dare to provoke it.。

On the other hand, for cultivators, they don't dare to go to the depths of the sea, so there are only a few water-based demon beasts that can reach the middle or late stage of Jindan in the near sea.

Therefore, it is not very optimistic to collect more than ten demon pills in the middle stage of Jindan or one demon pill in the late stage of Jindan in a short period of time. Therefore, the merchant suggested that the academy could go and hunt it by itself.

Therefore, Dr. Liu planned to make a trip by herself, and later felt that she could take them with her, firstly, it was also an opportunity to practice, and secondly, she also wanted to see their skills.

Later, Doctor Liu's disciple, even the woman wearing the mask, also wanted to see it, so he also wanted to follow.

Dr. Liu introduced her apprentice by the way, his name was Wu Wan, and he was twenty years old, older than all of them. You can call her Wanwan or Sister Wan.

Fei Fei was familiar with herself, so she talked directly to Wanwan and asked her why she was wearing a mask. She said that this mask is a newly developed spirit tool, which is mainly used with soul frequency, but it will take a long run-in time. Because she only uses it now, she has been wearing it for running-in, and when the running-in is in place, she can put the mask into her body.

Fei Fei was very curious and asked what is the purpose of this thing? It is so difficult, after all, everyone usually uses spirit tools as long as they use divine consciousness to refine, and they have not seen the spirit tools that need to be run-in.

Physician Liu explained on the side that this is a spirit tool that cooperates with the soul frequency, and it must be in harmony with the soul to have an effect, so there is a run-in theory. The function is mainly to protect the soul frequency,When someone locks,It can protect the soul frequency,There is no way to let the other party lock,The principle is that it can make the wearer's soul frequency fluctuate within a certain range,So that others can't figure out what kind of soul frequency you are。 Of course, with this function, you can also imitate other people's soul frequency, and it is even easier to block the soul frequency. In short, there are many functions to be developed, after all, it is a new spirit tool that has just been refined, and Wanwan is also the first to experiment.

"Why do you want to make a mask? It's too obvious, as long as you see someone wearing a mask in the future, you can clearly tell people that you can change the soul frequency!" Fei Fei asked.

Hao Yun actually has this question.

After hearing this, Wanwan said, "This can be changed, for example, I can make it into glasses." As she spoke, the mask on Wanwan's face turned into glasses, and Wanwan's face was revealed.

For this face, Hao Yun is relatively unfamiliar with the three, but this face is so beautiful, I can see that the skin is like fat, the eyebrows are like light smoke, fresh and elegant, the apricot eyes are shining, and there is a pair of glasses on the straight nose, which is fascinating!

Fei Fei took a breath: "It turns out that Sister Wan is a big beauty! “

Wanwan took Fei Fei's arm and said softly: "Sister Fei Fei is also a big beauty! “

Hao Yun was a little excited, he finally saw a real beauty for so long, he always felt that this place in the spirit world should be full of beautiful women. Who knows, let alone beautiful women, it is difficult to find a female cultivator who suits you.

Hao Yun smiled: "I understand why Wanwan is wearing a mask, if she goes out like this, it is estimated that someone will come out and rob the beauty." But with the mask, we have less chance of heroes saving beauty. “

Physician Liu listened and quipped: "It's possible, but no one has robbed a beautiful woman in these years, and now the security in the spirit world is not bad." “

Pan Shi also smiled: "It has nothing to do with public security, the main thing is that cultivators don't care much about their appearance, and it's not that they haven't seen a woman, who has nothing to provoke this, they don't know how to die." If a cultivator who can survive doesn't have this concentration, it is estimated that he will die a long time ago. “

Hao Yun thought to himself, that's you old guys, young cultivators definitely don't have this concentration, but it doesn't seem that there are too young cultivators, if you don't count them, at least 30 years old before building the foundation. But think about it, there should be no cultivators who rob like fools, unless they are particularly strong, otherwise a lock will be killed, and it is easy to be retributed for doing bad things in this spiritual world.
