The once bustling streets were now filled with corpses lying on the ground.

Because a large number of lives died in a short period of time, the environment was filled with negative energy, and some of the dead bodies quickly stood up again and turned into terrible undead creatures.

Among them, warriors, knights, and spellcasters who had very high professional levels during their lifetime are still evolving.

The tops of those magic towers that once stood tall no longer flashed with colorful and dazzling halos.

Either countless undead have already flooded in, ruthlessly killing all the living things inside, and eventually the entire tower has been eroded by the negative energy that symbolizes decay and death;

Or the wizards in the magic tower would actively cut off all contact with the outside world, shivering in their last fortress, and barely survive using the food in the storage room.

He no longer dared to conduct various magical experiments recklessly like before.

As for using the portal to escape to other places...

Sorry, that's no longer possible.

Because just fourteen days ago, a critically ill wizard believed that the situation was irreversible, and with the help of the power of the central tower, he released an extremely powerful confinement spell.

The entire city was completely locked in the air four thousand meters above the ground.

All teleportation magic, flight magic, and magic that slows down falling speed are completely ineffective.

Even birds that accidentally enter the range of the spell will immediately fall vertically from the sky and die.

The most terrifying thing is that this spell is valid for a hundred years!

This means that no one can escape.

Those survivors who have not died yet will die of starvation, thirst, or old age, unless they can find a way to live to the next hundred years.

Of course, if you think this kind of death is not heroic or exciting enough, you can also choose to rush into the streets and fight those undead, or jump from a height of four thousand meters.

…

This is the floating city of Plantia, the first floating city built by the original great wizards. It is also the center and pride of the El magical civilization.

But now, it is just a city on the verge of destruction.

In fact, similar things are happening not only in the floating city of Plantia, but also in cities and villages on the ground.

This horrific plague that came out of nowhere swept across the entire continent in just over a month.

No matter whether it was the "superior" spellcasters living in the floating city, or the warriors, knights, mercenaries, merchants, and slaves who lived on the ground and served the spellcasters, none of them escaped the disaster.

No one knew what caused the plague, or how to treat it.

The only thing the necromancers knew was that this horrific plague would continue to mutate and evolve.

All treatments can only temporarily relieve symptoms!

Then it won’t be long before it erupts again in a more ferocious manner!

Even the potions and spells that were once claimed to be able to cure all diseases only had a slight effect in the initial stage.

But soon, death swept in like a storm, killing thousands of people in a very short period of time.

Even many great wizards who were as high as gods died in the plague.

panic!

fear!

despair!

By now, social order has completely collapsed.

The very few lucky people still alive on the ground all hid in the deep mountains and forests.

Others even took a boat out to sea, planning to seek refuge on other islands and lands that were still in a wild state, physically isolating themselves from the possibility of contact with the plague.

In short, the powerful magical civilization built up by the Aiel people over a period of more than 2,500 years has been destroyed by the ravages of the plague.

Even if those immigrants who escaped eventually survived, they probably wouldn't have the courage to set foot on this land again.

It is even more impossible to restore the past glory and prosperity with the limited knowledge and resources at hand.

However, the wizard who escaped from the floating city would probably never have imagined that the source of this disaster that destroyed civilization was ultimately the result of a time traveler from Earth who accidentally caught a cold and sneezed.

Yes!

Just a little sneeze!

Judging from the destructive power of this plague, his body must not have been disinfected when he traveled through time, and he carried a large number of terrible viruses and bacteria from Earth.

After these viruses and bacteria came to this other world, they combined with magical energy and underwent some unknown mutations.

One day more than two months ago, Zuo Si worked non-stop for more than forty hours while creating a magical artifact.

As expected, I finally fell ill due to catching a cold, excessive fatigue and lack of rest.

As we all know, a cold causes sneezing and runny nose.

Sneezing, in particular, will spread a large number of droplets carrying bacteria and viruses into the air, forming the initial spread of infection.

All organisms that are unfortunate enough to come into contact with these droplets will automatically become virus carriers and then infect more people without knowing it.

In addition, people from other worlds have never been exposed to mutated viruses and bacteria from Earth, let alone immunity and antibodies.

As a result, a disaster broke out suddenly without any warning.

Looking at the dissecting table used for necromancy experiments on the first floor of the basement, and the corpse on the table that had just been ripped open, was still bleeding and emitted a pungent stench.

Zuo Si, who was only about 1.3 meters tall and looked like a child of about ten years old, couldn't help but sigh slightly, threw away the scalpel in his hand, stepped on a stool to release the little remaining clean water reserve in the tower, washed the blood on his hands, disinfected his whole body with high-concentration alcohol, then opened a diary and began to record in slightly sloppy Chinese characters.

"On August 12, 2535 of the Solar Calendar, the weather was a bit gloomy.

Almost a month and a half has passed since the outbreak of the plague.

One year, nine months and fourteen days have passed since I came to this magical world.

There are not many living creatures left in the floating city of Plantia.

Because too many lives died quickly in a short period of time, this city standing in the sky is transforming into the city of the dead at an unimaginable speed.

Even the proportion of negative energy in the environment is increasing exponentially.

It is foreseeable that it will not be long before this place is no longer suitable for living things to live in, but will completely become a paradise for undead creatures.

Conclusions based on the last autopsy and observation.

This plague should not be a disaster caused by one mutated virus or bacteria, but several, dozens, or even hundreds or thousands of them.

This is why the magic potion that claimed to be able to cure almost all diseases soon became completely ineffective.

Some of the dead had large patches of blisters similar to smallpox and chickenpox on their body surfaces, the density of which was so high that it made people's scalps tingle.

Some internal organs also suffered from severe failure, and with the collapse of the respiratory system, even the alveoli completely rotted away.

The digestive system, including the stomach and intestines, was covered with the black spots I had never seen before, which should be the result of bacterial action.

These spots rob the body of nutrients that would otherwise be absorbed, making the victim's body increasingly weaker and expanding recklessly in the body like cancer cells.

What’s even more terrifying is that after the corpses that have been dead for many days stand up again and become undead, they can still serve as sources of infection for a long time.

This means that mutated bacteria and viruses will not die with the death of the host.

They adapted to this magical world and became ten thousand times more terrifying than they were on Earth.

In the tower where I live, all the apprentices, warriors, knights and slaves on the middle floors, as well as the various monsters and beasts in the dungeon, have been killed.

Only I and the female red dragon, Wilmes, who was captured from the other side of the portal and kept in the lowest level of restraints, completely isolated from the outside world, are still alive.

As for my mentor and collaborator, Asta, the owner of this tower and the chief wizard of the Necromancer faction of the Magic Council, he had disappeared long before the outbreak of the plague.

I guess he is holding the notebook snatched from an old wizard in Faerun, hiding in an unknown place, trying to transform his old body into an immortal and powerful spellcaster - a lich - through cruel and terrifying magic rituals.

Of course, none of this matters anymore.

Anyway, the floating city has been completely locked down by magic. People inside can't get out, and people outside can't get in.

Apart from that, there was nothing to eat in the tower.

The warehouses where the food was stored were contaminated by negative energies and the bodies of dead slaves.

Thankfully, I already had a plan for my escape.

Finally, I want to emphasize that I really did not mean to cause this plague.

It was just a terrible accident..."
