Studying plague is a taboo, which is one of the reasons why necromancers are not popular. Because the reputation of the Scourge of the Dead is just too bad.

But magicians who study life and heal can also cause an uncontrollable plague due to their mistakes. Several times the pandemic plague that ravaged the land was all made up in this way. In comparison, the undead scourge is an intuitive threat, and everyone knows how to react. But the plague caused by the runaway magic was already dead and wounded by the time people were alert.

The above is the situation as it is generally understood.

For those who really want to save lives, they will know that there are some diseases that only exist in a small area, but they are contagious, and there is a high probability of dying after infection. What's more, the current mysteries do not know the cause of these diseases, and they say that they are caused by nature, but what is the cause? Saying that it is the plague research of some necromancer, where is the evidence?

Most people's concept is to blame the cause of the disease on the slave god of the lord of the underworld, the god of the plague. It's a concept that's been shaped out of fear.

And the known treatment modalities also appear to be limited. Some herbs can save some people, while others can't. In addition, there are all kinds of strange treatment methods, which are difficult to describe. Again, those strange methods, like herbs, don't work for everyone.

If the lich in front of him had just been talking about these terrible diseases, perhaps the twenty-four magicians below would have attacked on the spot and slain the evil. However, the lesion, the main cause of infection, the route of infection, the method of prevention, the symptoms of the disease, and the treatment method can all say something, although not all of them are complete, then the meaning for these people is completely different.

For a long time, the only way to deal with diseases was various potions, secret recipes, and the magic of the gods, and there were not many parts that magic could do. However, herbal medicine may cure the disease, or it may cure the life, and more often than not, it will not help.

Divine art also has its limits, or levels. There are many gods who can give healing magic, but the most common monks can cure diseases such as coughing, sneezing, diarrhea, weakness of limbs, etc., or minor diseases caused by the curse of the god of epidemics.

In the event of a serious illness, such as a high fever and coma, amputated limbs, severe poison, etc., a higher level of priesthood may be required for the treatment of the disease to be effective.

No matter how serious it is, it has to be a bishop-level person, and it is possible to be reborn from the living dead, flesh and bones, and severed limbs. But even so, there are diseases that cannot be cured by divine magic. At this time, the usual rhetoric of the church people will be that the curse is too deep and powerful to be eradicated; Either the patient is not religious enough, so the gods are reluctant to respond to his requests to restore his health.

Despite this, the disease has not received much attention in the mystery. The reason is that, first, the physique of the Homo sapiens species is quite excellent, and unqualified individuals will be eliminated at a young age.

Just like the reason for the high mortality rate of children in the era when earth medicine was not developed, it is easy to get sick and die in the process of growing up, and there is no chance to grow up with a sick body. So as long as it's an adult, it's mostly 'healthy'.

Second, there are so many dangers, both natural and unnatural, that the average person has little chance of worrying about such a 'triviality' as dying of disease. Usually before that, they will die from direct or indirect damage caused by monster attacks and wars. Of course, there are also incidents caused by magic or magicians, such as a scourge of the undead, or an accident, the mage lost a forbidden spell or something.

Even though most people don't care about disease, they only care about Warcraft or war. But for those who want to save lives, illness is the same as the other two, and it should not be taken lightly.

In particular, the long-term suffering caused by illness and the pressure on the people around him are far from being comparable to the injuries that kill people in a short period of time like war or monster attacks. In order to avoid this, in some remote places, there is also the bad habit of taking seriously ill people into the mountains and forests to abandon them.

If these diseases could be prevented, or if there were more accurate ways to cure them......

Thinking of this, the old scholars sitting at the bottom could not hold back their excitement, and even forgot the etiquette of the class, or the respect that should be maintained in the face of a person who imparts knowledge. They immediately asked their own questions, wanting evidence that would prove everything the lich had said, even purely emotional statements.

The whole classroom was suddenly noisy, even worse than those children who had just come to the initiation class.

Fen snapped her fingers and silenced everyone in the classroom except her. No matter how much you open your mouth, you can't make a sound.

At this time, everyone realized one more thing, this person in front of them was a lich who was once called the 'Demon King' and was more than a thousand years old. The depth of her magical prowess is not yet known to all; But everyone understands that now their lives are in the hands of the other party. A magician who has fallen for silence is only slightly better than a fish on a chopping board.

At this time, in addition to trying to escape, all you can do is to quietly cooperate with the caster's request, and maybe there will be a chance.

Seeing that everyone had calmed down and did not lift the silence technique, Fen said: "I can't do it when you ask me to prove that these bacteria are the main cause of the disease. Or I ask the other way around: Can you find other causative factors to disprove my view? That kind of thing caused by divine power, don't say it to make people laugh. Everyone is a magician, and the kind of things that you don't understand are pushed to God, and there is no more lazy behavior. ——”

Fen himself replaced the picture on the screen of the Water Mirror, which was a collection of pictures of the Dead Village.

As for those who suspect my connection to these villages. All I can say is that I did not cause the destruction of these villages; I'm just observing, sampling, and documenting. And I didn't have the ability to heal at the time, unless you think it's a good idea for me to resurrect an entire village as an undead being. But basically I don't want to run around with those burdens, and I don't want to let my creatures run around after they are resurrected, so basically I ignore the end of those villages. ——”

There are constantly people going to open up wasteland, some people have stood firm, and some people are buried in the wilderness. Therefore, in the process of traveling, the news of the extinction of a certain village was heard from time to time. There are many reasons for this, such as the attack of monsters, unknown strange diseases, and the inability to obtain enough food to survive the winter. That's why adventurers are needed to be professionals who can deal with incurable diseases to protect these civilizations outside the city walls.

In other words, the scene that the lich saw in front of him didn't need to be deliberately created at all, it was simply the daily life of the land.

In the end, Finn replaced the two pictures side by side, and everyone only felt inexplicable. Only Lin knows its significance. The picture on the left shows a moldy orange, and the strain is single, not colorful. The picture on the right is mold under a microscope.

"—and about the method of treatment. In addition to those who don't know the so-called secret recipes of herbs, I also have preliminary discoveries about the possible types of medicines. Some of the moldy food extracts in the moldy area can kill the bacteria. The moldy part is micromagnified and is shown in the picture on the right, which I call 'mold'. But because I didn't have a smooth environmental study during the journey, there wasn't much progress in that area. The main reason is that there is no way to collect mold in large quantities and determine which ingredient extract is really effective and can be used to kill bacteria. Moreover, the amount of extract is not enough to provide the amount needed to heal the human body, and these parts are still to be studied in the future. ”

The magicians who couldn't speak were all eyes lit up when they heard Fen's expectations for the future. If this thing can really succeed, not to mention that it can save countless people, it can also gain a full reputation.

For most magicians who have come to the end of their lives, in addition to the mood of saving lives, they only care about the name behind them. In other words, can you leave any legacy that is truly beneficial to the world. Instead of dying, everything he has done and built will be scattered with the wind, as if there was no such thing.

So the idea that everything was silenced and that life was threatened was kicked out of the clouds. All of them are holding back their strength, wanting to achieve something in this new science.

Of course, Fen could understand what the desire in the eyes of the group of people below was. As he lifted the spell of silence, he said, "But don't think too much about it for now. If a lot of the knowledge you should have is insufficient, you don't need to explain the harm caused by doing it blindly. At least you have to understand that there are many drugs that can kill bacteria alone, but drugs that can kill bacteria may also be poisons that can kill normal human cells. How to find a drug that only targets bacteria and can not cause harm to the human body, we must first understand the differences between them and the mechanism of operation. These are all scheduled to be taught in the following lessons. And as a magician, of course, there are more than that. ”

At this time, Fen used the whiteboard pen technique to construct a rather complex spell model in mid-air. Because of the recovery of spellcasting ability, not to mention self-preservation, there is no big problem in escaping. So the people below didn't panic too much, but calmed down and saw what this person wanted to do.

Although the spell model is complex, it is a magic that everyone present is familiar with—the Advanced Healing Technique, which some people call 'Rebirth of a Severed Limb'. Non-apprentice-level magic, even if it is a formal magician, can be a bit difficult to learn. This is because this magic is a high-level tactical magic derived from the undead, and it is used to regenerate limbs of corpses and undead.

As long as there is 'sufficient' power to support it, any kind of disability can be reinstated, but there is still a possibility of failure. But the 'enough' here is not a level that can be beaten with a few magic stones.

Compared to the same effect, magic is much more expensive. It is so big that this magic only has reference value, and even if the magicians themselves need it, they would rather spend money to find the Lord of Life Priest of the Three Holy Light Church.

Looking at the half-empty spell model, Fen sorted out his thoughts for a moment and said, "The healing technique and the treatment of diseases in the divine art correspond to the disability and disease of the limbs, respectively. But in the realm of magic, there is only one healing technique for limb disability, and there is no magic to cure diseases. For a thousand years of my ban, it always was. There are so many researchers, but there is no breakthrough in magic, but has anyone wondered why? ”
