The casters thought that as long as they eliminated the invisible plague inside the lock, they would have hope of saving their compatriots outside the lock.

However, things did not change for the better, and a more terrible situation emerged.

The arcane art of organ preservation, in order to achieve the purpose of perpetuating the target organ, is to destroy all life without discrimination.

Half-informed epic casters use it to eliminate the culprits, as well as the essential beneficial microbes in the human body.

For example, the intestinal ...... that help with digestion

The first strange situation that occurs is that people eat food, the digestion rate is very slow, and the excrement is dry and hard, which is very easy to damage**.

People should not go without food for a day, and if there is a problem with the stomach and intestines, it will definitely be discovered immediately.

Along with this, there were malignant symptoms such as stomach pain and intestinal perforation, and the spellcasters, who originally lived in two worlds with almost ordinary people, had to rush to heal in a hurry, and expelling diseases became the most familiar arcane arts, occupying the most spell slots......

Fortunately, the caster himself is under the protection of many protective spells every day, and he has not suffered from microorganisms, so he has not encountered the embarrassment of losing microorganisms, and he can still go back and forth on the way to help others, otherwise when Qi Yuan arrives here, what he will be left with is likely to be a "prehistoric civilization ruins".

Epic spellcasters who don't know the real reason don't want to be trapped in an isolated city, but at least connect with other cities, and then find a way to rescue their people scattered in the wilderness, while finding the origin of the plague and solving the problem at the root.

Of course, this is just wishful thinking on their part, a global hotbed of microbes, and the planet of this period is simply an oversized incubator.

The two easiest ways to solve the problem at its root are the simplest.

The first is to burn the entire planet, so that organic matter is converted into inorganic matter through combustion, which cannot multiply microorganisms, and at the same time, high temperatures can also kill a large number of microorganisms.

However, combustion will also emit a large number of harmful gases, and this method, not to mention whether humans can tolerate high temperatures, breathing alone is enough to kill people.

This can be eliminated directly, and the other is to freeze the entire planet, the colder the temperature, the less active the microorganisms are, but as before, people and other organisms will not survive.

With Arenada's population, science and technology, it is necessary to expand the scope of the Mystery and move the limited population together, waiting for nature to adjust itself and the entire ecological environment to re-enter a state of equilibrium.

Or just build enough spacecraft, hide in space for a while, or wait for the natural recovery of the ecological environment on the ground.

As for the development of medicine, the head-on confrontation is not to underestimate the wisdom of the Arenadas, but that their population loss is too severe, and they were not able to cope with it at the beginning, losing the best opportunity for development.

Waiting for their limited casters to summarize the targeted medical results in practice, it is estimated that there will be only a few Arenadas left to die.

Qi Yuan listened to and watched Mycenae VII's story, and automatically translated the disaster that happened to Arenada into his own understanding.

Although the people of Arenada call "microorganisms" "plagues" and confuse bacteria and viruses, and do not know the difference between "beneficial bacteria" and "harmful bacteria", Qi Yuan himself can see it through the images.

However, he did not rush to express his opinion, and now that decades had passed, he was greeted by the living Arenadas, who had apparently found a solution on their own, and who only needed to listen.

Immediately afterward, several epic spellcasters who couldn't find a clue set off separately and went to all parts of the country to check the situation.

At this time, there were already many villages, towns, and small cities, and only the remaining spellcasters and priests were still alive, and even other combat professions were difficult to survive.

Some of the casters who had lost all their relatives and friends chose to commit suicide, and the entire settlement was no longer inhabited, and the bones of the whole country were exposed, and there was no one to collect the corpses, and the corpses decomposed extremely quickly.

The other three cities with lockdowns have also been curbed after receiving the capital's "epidemic prevention measures", but the problems they face are exactly the same.

The casters began to leave the Locks and go to the wilderness to find the survivors, bringing them back to the city for treatment, and hoping that the survivors would have their own unique skills to solve the problem.

More than ten years have passed, fewer and fewer people have been locked in the lock, the elderly and children have died first in the earlier disasters, the prime of life has also been exhausted, and for more than ten years, the number of newborns is very small, and the whole of Arenada has fallen into despair.

The gods never answered the prayers of the believers, which led them to think that they had committed unforgivable sins and had been punished by the gods.

Fortunately, some spellcasters have not given up hope, and they have learned a little bit of the truth from the preservation of organs, although they can't tell the truth, but they also have some intuitive understanding.

In the end, the epics who never gave up found the druids who escaped into nature, and these darlings of nature have quietly returned, and they have their own unique methods to save some ordinary people.

But the number of druids is too small, and while they are treating ordinary people, they are also stumped by ordinary people.

By communicating with nature, the druid distinguished pathogenic bacteria from non-pathogenic bacteria, just like Qi Yuan perceived divine magic, thinking about what purpose to achieve, he found a targeted divine technique.

This "exorcism" is much better than the preservation of the organs of the arcane spellcaster, but ordinary people are constantly in an environment rich in microorganisms, and they can be reinfected at any time.

The druids couldn't leave.

The reunion of the arcane spellcaster with the druids puts an end to the microbial infestation.

In the end, there were only four cities left in Arenada that were protected by the Lock, and only inside the Lock, the germs would not flood in large numbers once they had been destroyed.

Outside of the lock, the place can only belong to nature.

At this time, Qi Yuan suddenly realized that when he entered the city, the people who knelt down on the ground and saluted, may not be forced by any etiquette or rules, they are likely to sincerely revere the four epics who greeted him.

Without these casters, Arenada might have really vanished.

Qi Yuan sighed very emotionally, what happened to the earth in the integration of the world may be very unfortunate, it faced the invasion of the dream chrysalis, and all mankind was caught off guard by hatred.

But the earth is at least under the care of the gods of nature, and even if humanity suffers losses, it has never really encountered the danger of the extinction of the entire race.

And Arenada, who seems to have made peace, did not meet the expected luck. ()
