"Drought thunder?"

"How did the temperature drop? Is it my delusion?"

"Just a moment...... It's scary, it feels lifeless. ”

With a terrible and sharp deafening thunder and the illumination of an instantaneous white electric light, there was a series of commotions in the transfer team, and the first combat team that reacted hurriedly maintained stability.

Kara stepped out of the queue and yelled at a group of incapacitated people who were frightened by lightning, "Stand up for me, what's there to be afraid of? It's just thunder, haven't you been weaned yet?"

Hermione looked up at the gray sky of the day and whispered in Arre's ear, "It's not just thunder...... At that moment, you should know better than I feel. ”

The Black Knight did not answer him, but suddenly lay on his side and pressed his ear to the ground—in the depths of the unknown, there was a dull and sluggish low rolling, like a river weaving through the earth, intertwined into a strange rhythm...... It's like the breath of a giant...... It's like the fetal movement of some kind of behemoth.

The sound shot straight out from the depths of the earth, exploded intermittently in his ears, and got closer and closer......

"Hey, why don't you reply?" the alchemist was displeased, pouting and looking at the other.

Yalei jumped up from the ground suddenly, and his voice suddenly drowned out the noise in the group: "Immediately turn the direction of the team and go back to the library!"

"But......" The knights in the back row seemed to want to say something.

"Do as I say!" the Black Knight told them to shut their mouths, maintaining their apparent calmness and composure, and gave the order directly to the team:

"Everyone turn back and run back as fast as you can, right now!"

"Let's go!" Alcia and Beverly looked at each other, nodded, and immediately turned and ran to the library's vestibule.

"Don't mess up, don't mess up!" Kara and the others still remembered their duties, keeping the ranks in order to avoid a stampede.

More than 6,000 people poured into the library like the sea water in the ebb tide, and when the black knight of the palace entered the vestibule, Bruno walked quickly to him and asked:

"What was born, and why did you suddenly retreat?"

"Something has to come out of the ground! As he pointed to the earth, his expression tightened, and he shouted around:

"Hermione, get Hermione!"

The silver knight's fine eyebrows furrowed slightly, and his whole face became sharp:

"From underground?

"Who knows...... There's something more important for you to do than that. The black knight suddenly pressed his shoulders: "Divide all third-order knights into three categories: good at defense, long-range, and white-knuckle combat! Please, try to be as fast as possible!"

"Understood!" Bruno replied without thinking, jumping onto the altar to the side:

"All the third-order knights come and report! those who are good at defense stand on my left, those who are good at long-range attacks stand on my right hand, and those who are good at white-knuckle combat ......"

"Alas, alas, alas, pain, pain!" Hermione was grabbed by the wrist of a tall knight's apprentice and brought to Arley, and said with a reluctant face:

"Since you have returned to the library, our agreement will naturally be cancelled, what are you looking for me for?"

The Black Knight ignored her nonsense and asked directly, "Your defensive barrier should still be activated, right?"

"Of course, there are still a lot of magic stones left, and my defensive enchantment is very special!" As soon as he mentioned his specialty, the alchemist immediately entered the state of speech, and raised his index finger in joy:

"Once activated, it can passively absorb the free mana in the air, which can save about one-third of the magic stone consumption, and the level of energy saving is absolutely long......-lasting!

"Stop!" Seeing Hermione's mouthful, gushing appearance, Yalei could only forcibly stop her words: "All-round defense?

"Of course, what time do you think it is? The alchemist glanced at him unsatisfied, rubbed his wrist, which was still painful, and said angrily:

"It is not uncommon for legions to be killed by the explosion of chrysanthemums because of negligence in underground fortifications, and this product was opened twenty years ago. ”

Speaking of this, she smiled embarrassedly:

"But...... Because it's just an experiment, the two-way enchantment I use can be remotely controlled, to put it simply, it is to take care of the top and the bottom, and the bottom and the top. ”

"That's enough!" A heavy stone in the black knight's heart suddenly fell, and he carefully advised: "Reopen the barrier and defend against the underground, this is related to the fate of more than six people, and I will leave it to you!"

"Okay!" Hermione, though dissatisfied, was not the kind of person who didn't care about the big picture, and besides, her own life was included, so she turned around and trotted into the library.

"Ahh

Within a few seconds, she ran out with the students who had just entered the hall, with a pale face and screaming without words: "Bugs!

"Bug!?" Areh was walking towards the queue of alchemists, preparing to temporarily organize them into remote teams, when he heard the sound and immediately rushed into the library hall.

As soon as he entered the door, a strange creature the size of an adult sea turtle bumped into him, its structure and peculiarity, the torso was in the shape of a long loaf, and each had five tentacles behind it, three on the head and four on the tail. It has no eyes, a circle of disgusting small tentacles open on its side, and its body is pale in color, covered in a carapace that looks like scales.

For this disgusting creature, Yalei didn't even want to use the Falcon Sword, and directly scorched with black fire, and before the white smoke could rise, seven or eight more immediately collided with it.

The Black Knight stretched out his hand and spewed out a pillar of fire, sending them back to nature, looking around—the floor, the stone pillars, the walls, the dome, and everywhere there was a dense density of these giant insects.

The four corners of the hall, where bookcases are piled up, are the most concentrated, and from the outside, you can almost only see a "large insect ball" that is constantly surging, and the sound of crackling and gnawing wood can be heard from the inside.

"It's a book silverfish! an enlarged version of the little worm in the page, they must have mutated!" said one of the knights, swallowing his saliva.

Hermione hid far behind them, jumped to her feet in a hurry, and shouted frantically, "Kill, kill, kill them all, don't let them destroy the circulation system of the defensive barrier!"

Yalei took a deep breath, suddenly burst into his tongue, and shouted, "Don't go in yet, everyone!"

In an instant, the steel fighting qi was concentrated in the palm of the palm with the most violent attitude, and a long dragon-like black pillar of fire was sprayed, like a surging tide in all directions, forming an impenetrable giant net of flames, burning insects into charcoal while not harming others.

The students who were stranded in the vestibule suddenly appeared, and bursts of thick white smoke suddenly wafted out of the library, mixed with a strange fragrance like roasted sweet potatoes, and poured into their nostrils, and many people were aroused by this.

"Didn't you say killing insects, why is it so fragrant?"

"Does it smell like burnt bugs...... It feels delicious. ”

"Don't be funny, it smells fragrant, and you may die if you bite it. ”

In just a few tens of seconds, Yalei didn't know how many book silverfish had been burned, about more than the bread he had eaten so far in his life, and after getting rid of most of them, he asked some of the knights who followed up to continue to clean up, and dispose of the insect corpses by the way.

Leaving behind a scorched insect corpse, the black knight walked to the entrance of the basement with a small number of knight apprentices, and when he got closer, two of them spit out directly.

The entire basement is filled with white-flowered, wriggling larvae!

Perhaps because of their hunger, these disgusting creatures are still frantically gnawing on their own kind, not so much gnawing as sucking, because they have no teeth, only pinpoint-like mouthparts.

Due to the special mouthparts and the fat body size, there is no room to dodge, these insects have to maintain a chaotic cycle of you sucking me, I sucking it, and it sucking you.

So much so that sticky white bodily fluids were sprinkled everywhere, and the fattest ones were already scaly, and even the eggs attached to the basement walls were not spared.

"I've checked before, and there's clearly nothing here. As Yalei spoke, he waved out black flames: "What kind of power is it...... Can you make these bugs ten million times bigger in a short period of time?"

"It's probably the same kind of power that makes the animals mutate. The knight to his right replied.

"What about the books, there are a lot of rare books in it!" said another knight's apprentice, with a worried expression.

The knight who had just vomited came over and pinched his nose and mocked: "Come on, these insects are so hungry that they even eat their own kind, and the books in them can still survive?"

"The basement, the books, I don't want them!" the black knight was ruthless, and the flames in his hands were so strong that the thousands of larvae in the basement turned their bellies open in the blink of an eye and were dried into shriveled lumps.
