If Arenada and Earthlings change places, it may be a good thing for both parties.

Although Qi Yuan is not as good at medical skills as Huang Xiaoxiao today, when he encounters a problem, he can still correspond to which information should be queried.

Qi Yuan is confident that he will help the people of Arenada adapt to the current planetary environment as soon as possible.

In fact, if it weren't for the sudden change in the environment caused by the convergence of the world, nature would not have reacted so violently.

Just as the familiar food chain exists in the upstream and downstream constraints of animals and plants, in fact, there is also a mutually limiting dynamic equilibrium between microorganisms.

According to the laws of biological evolution of nature, there will not be a period when a single species is suddenly strong enough to completely destroy the ecological balance.

Microorganisms, of course, are not exempt from this law.

In fact, the best solution should be to find a targeted plan to kill pathogenic bacteria, viruses, fungi and other microorganisms, and then migrate away en masse, go to space or other planets, live temporarily, and wait for nature's self-regulation.

As long as repeated infections are avoided, the disease is not difficult to fight for the Arcane Arenadas.

And microbial flooding cannot last long, because the biological structure is simple, and the life of microorganisms is really fragile.

Some can't survive on their own at all, and can only survive on certain cells of animals or plants; some can't withstand long-term sunlight exposure, ultraviolet, infrared and even visible light may cause direct damage to them; and some have a very short life cycle, they have a good breeding environment, the number is extremely large in a short period of time, although it looks terrible, but a good breeding environment will not always exist, time will make them disappear soon after the boom.

In fact, by the time Qi Yuan arrived, nature was almost healed.

After decades of adaptation, animals and plants have been re-decomposed into nutrients and covered the earth with the extinction of extinction and evolution, and those that have not been able to resist environmental upheaval and microbial invasion.

Therefore, when Qi Yuan looked at it from afar in space, he felt that the planet below was blue-green.

The atmospheric environment with high oxygen content is very suitable for plant growth.

Of course, it is also suitable for the growth of animals, in an environment with extremely high oxygen content, it can allow the development of carbon-based animals to be huge, and sufficient oxygen can ensure the energy supply of large bodies.

The reason why the Arenadas named the "lizards" they found here "wurm" is because these animals have just evolved from amphibians to reptiles, and they are so large that they are comparable to the dragons of Evangeliel.

But after all, they are only large, and they do not have the superior intelligence of the dragons, nor the powerful abilities of the dragons.

Perhaps, in today's universe, in such a magic-rich environment, after a long period of evolution, they will also have the opportunity to grow into primitive intelligent races such as "dragons", "orcs", and "gnolls"!

Two hours later, Mycenae VII's account came to an end, and Arenada was now in ruins, with a population of more than 500,000.

It was only in the last few years that spellcasters noticed that the environment outside the Locks had begun to improve, and the "Invisible Divine Punishment" had disappeared, and people had come out of the Locks again in an attempt to rebuild their homes.

Qi Yuan felt a little embarrassed, but fortunately he didn't rush to help others solve the problem just now, it turned out that time had already solved the problem.

Thinking about it, if the natural environment was still so bad, he would never be unaware of the unlocked lock when he followed Yinglier and others into the city.

When magic is in its original state, it is indeed colorless, odorless, and difficult to touch, but just like electricity and heat, once it reacts with other substances, it will cause fire, smoke, ice, and so on.

At this time, it is the stage where humans can perceive.

Therefore, when magic is transformed under the action of arcane and various spell effects are formed, sound, light, and color are very conspicuous.

Unless it's intentionally obscured and modules are added to the arcane model, the auraes are absolutely dizzying.

But what about the limited range of arcane that can cover up the mysteries that envelop an area at once?

Just like the Quenching Sword Fort and Bangalore, when the Mystery Lock is not opened, it looks like an ancient city surrounded by walls, and once the Mystery Lock is opened, it will immediately become a future city wearing a multicolored energy shield.

Arenada is no exception.

Qi Yuan suddenly realized in his heart that he didn't see the lock open, it turned out that the tide of microorganisms had passed.

In fact, there was a similar period on the earth at the beginning, but because the earth as a whole was in a period of abnormal climate, coupled with the fact that human beings had a more comprehensive understanding of the world and coped with it, microorganisms did not have too much impact.

Finally, Mycenae VII asked, "Dear Astral Wanderer, have you ever seen anything like this during your vast astral journey?"

"Our polymath has not been able to find the source of the 'plague' or the reason for its disappearance. ”

Qi Yuan nodded slightly, and saw that the people of Arenada were all excited.

"Everyone, don't be impatient. Qi Yuan thought about it and said, "I roughly guessed the reason, but it still needs to be confirmed." ”

Regarding the speculation of microorganisms, although Qi Yuan said that he was sure in his heart, he could not pat his head and draw conclusions without empirical evidence.

"Confirm, what should be done?" Yinglier couldn't wait to ask, he had seen the inside of the Breakthrough, and he had some blind confidence in Qi Yuan.

"I have some speculation about what happened to you, but I need to find evidence. Qi Yuan smiled and said to everyone: "This requires the remains of several unfortunate people who died of the 'plague'. ”

"This ......"

People other than Qi Yuan looked at each other, and in the end, Mycenae VII decisively agreed: "Yes!"

"Oh, that's right!" Qi Yuan suddenly thought that he had to be meticulous about the requirements, Arenada people were not those scientific research workers who were used to doing laboratory work, and under simple conditions, the experimental materials found might be in vain.

"The victims must have the same symptoms as other 'plague' patients before death, such as high fever, vomiting, diarrhea, etc., and they must not have been treated by magic before death. ”

Qi Yuan was worried that the Arenada people were looking for individuals who had died due to organ failure after being treated by expelling diseases, so it was difficult to say whether the microorganisms that could remain in the corpse were pathogens or not.

"Also, the closer the time of death is to the present, the better, and the more bodies that can be found, the better. ”()
