Deep in the dimly lit crypt.

There were dense scarlet eyes in front of me, and the shrill sound of rats.

Liena's face was a little pale, she wasn't afraid of the rats, which might pose a slight threat to the average caster.

But she's a wizard who specializes in fire magic, and she's best at cleaning up this large area of the "strange sea".

What really frightened Liena was that the number of rats reminded her of the terrible plague recorded in the Imperial Library's books—the Great Plague of Justinian!

It is said that during the Great Plague, a large number of cities in the empire were reduced to dead cities, countless fertile farmlands, crops waiting to be harvested were abandoned, and a third of the entire population of the empire was lost.

In Constantinople, the most densely populated city, thousands of people die every day.

In the face of the plague, whether it was the royal nobles living in the purple family, the bureaucrats and magnates in high positions, the brave and warlike generals, or ordinary and humble civilians, they were all killed without discrimination.

The wooden carts loaded with the bodies worked around the clock to transport all the bodies out of the city.

They can only be left to lie in the streets and alleys wrapped in mats, waiting to rot and be eaten by rats and mosquitoes.

She was impressed by an illustration in a book about the Great Plague.

It depicts a ghoul with sparse green hair, shriveled skin, mummy-clinging to a skeleton, and a belly the size of a pregnant woman.

Lying on his stomach in the pile of corpses, he feasted until his belly burst open and the flesh in his stomach pouch flowed to the ground.

Ghouls, monsters that never seem to be able to fill their bellies, have forced themselves to death, and you can imagine how many people died in that disaster.

Liena opened her hand, and the fireball that was originally used for lighting suddenly expanded, turning from a fist-sized orange-red flame into a golden fire snake, swallowing the flame snake letter and staring at the rats.

Maybe it was the sudden rise in temperature that stimulated the mice.

Squeak –

Dense rat chirps, accompanied by an endless swarm of abscesses beneath the wet hair, swooped down on her like a tsunami.

Rumble.

The golden fiery serpent flew out, and in an instant, it set off boundless flames in this narrow underground world.

I don't know how long it took.

The fire began to grow smaller and gradually extinguished.

The horde of rats that had previously seemed to engulf all living creatures was now left with the burnt smell of burning fur and flesh, and the lingering smell of rot.

Liena covered her mouth and nose, frowning at the dark ground with a thick layer of black ashes, and her mood did not change much, because she knew very well - the rats in the dungeon could not be killed.

A colony here is disposed of, and in the invisible corners, there will be many more rats, and it is impossible to clean them up without finding the root of these rat colonies.

Anna must be notified.

She took out the double-headed eagle crest she had with her, brought it to her lips, and lowered her voice, "I need support, Anna, bring Eve and Lothar to help me at once - I have discovered a catastrophe that could bury the entire empire." ”

As she spoke, she was about to leave the dungeon when her footsteps suddenly stopped.

She held her breath, and she didn't dare to catch her breath.

Listen carefully to the movement in the distance.

Is it a rat?!

Liena's eyes widened, not caring that the mud and filth under her feet would splash on her clothes, and she recited a magic shield spell and ran desperately towards the entrance of the tunnel on her two long legs.

With a loud bang.

The bricks cracked, and the wall above her head cracked countless cracks, and from the cracks, countless disgusting rats full of abscesses were desperately burrowing in, and in the blink of an eye, the cracks quickly expanded to the top of Liena's head.

Liena gritted her teeth, and the rats rained down like drops, smashing into the magical shields around her body, exploding into clouds of filthy marks of flesh and blood.

She realized that she had done something stupid, and that she had used her Flame Explosion technique to burn the bricks above her head open.

The movement attracted the neighbors of this rat pack again.

She ran as hard as she could, and vowed that if she could escape this time, she would learn short-range teleportation no matter what! Or go bankrupt and buy a treasure with a small teleportation array inscribed.

Damn, even if you can't do that, at least learn a levitation technique.

Liena looked back at the rats that were pouring in like a tide, and a trace of despair could not help but arise in her heart.

…

Imperial Library.

Lothar squatted for a long time at the pool, which was said to lead to the Golden Horn, and did not see "Niko" again, a ripple on the dark and deep surface of the pool, as he reached out and touched it.

"What kind of sea dragon is Niko?"

"I don't know, but it's definitely a pure-blood sea dragon."

Anna looked at Lothar with a skeptical expression, and said helplessly: "I really don't know, there are so many dragons in this world, many dragon species even exist only one or have long been extinct, sea dragons are even rarer than land dragons - you can't expect sailors and transcendent zoology experts to see a dark shadow swimming underwater, and they can depict its body and features, right?" ”

Lothar was stunned.

"So the sea dragons are all collectively called sea dragons?"

Anna nodded, "That's right, and Niko is still in her infancy, and she will peel her skin a few more times in the future, and her body shape characteristics may change even more than now." ”

That's sort of. Metamorphosis?

Anna's words awakened Lothar's long-dormant knowledge of biology.

"Stop squatting there and playing in the water, I'll show you something good."

Anna took Lothar and walked slowly up the stairs from the top floor of the library to the lower floor.

She pointed to a bookshelf next to her and said, "From the left, in the first row of the third row, the red book with a calfskin cover is a dragon life illustrated book, the masterpiece of Master Lateran, you may be interested." ”

Lothar nodded, "Thank you." ”

Anna frowned, and said, "Although I don't know how you filter out the madness factor in the dragon's blood and maintain your own humanity, I still have to warn you, if you are not sure, you should not continue to absorb the dragon's blood in the short term." ”

Of course, he accepted this.

Lothar is actually also affected by dragon blood, but the "dragon bloodline" as a system definition is much weaker than the "dragon blood" in this world.

Seeing that Lothar was still walking straight to the shelf and pulling out the red-covered book, Anna had to snort softly.

"I don't want to hear the news that a black dragon has appeared in Jerusalem one day, and I won't refuse when the time comes, when your little king asks me to round you up."

Lothar smiled and replied, "No, don't worry, I'm just a little curious." ”

A complete illustrated book of dragons is of course of great significance to Lothar.

Dragons are said to be rare, and they are rare, and they are not rare, and they are not rare.

He was able to hold the dragon blood of ten different dragons, and now he has six copies.

This equates to six out of ten skill slots.

Next, he didn't plan to casually find some dragon creatures to make a living, such as elephant trunk dragons, short-necked dragons, which are slightly stronger than ordinary monsters, and the dragons hunted in the knights are often these low-level dragon beasts.

Not to mention the strongest known copperhorn fire dragon, at least some higher dragons such as Spinosaurus must be hunted.

Seeing that Lothar was fascinated, Anna smiled and was about to turn around and go downstairs, when she suddenly felt a burning sensation coming from the double-headed eagle crest hanging on her chest.

She picked up the coat of arms and immediately recognized that it was Liena contacting her.

"This guy can't be disgusting on the way to clean up the ghouls and plan to throw the pot at me, right?"

Anna quickly connected to the communication, her face turning pale with the rapid sound of voices inside.

"Lothar, I need your help."

Without thinking, Lothar said, "No problem. ”

Seeing that Anna's face was different, he immediately closed the book and put it back in its original place.

"In a hurry?"

"It's urgent."

"So what are you waiting for, let's go at once."

Anna opened her mouth, but didn't say a word of thanks, just grabbed Lothar's palm.

"Empty your brain, don't think nonsense, I'm going to use the Imperial Library's teleportation array next, the process may be a little uncomfortable, but it's good to get used to it."

With a flash of white light, the two had disappeared in place.

In the corner of the library.

Eve was engrossed in reading a book on spell models when a hand suddenly reached out from behind her back and grabbed her arm.

"Huh?"

The unkempt witch only had time to let out an exclamation before her figure suddenly vanished.

All he was left with was an open spell book, which fell to the ground with a thud.
