In just half a minute, countless fat book beetle larvae were burned into charcoal by the steel bucket gas, and finally turned into charcoal powder, which was piled up half a foot high in the basement.

"Someone will clean it up later. Areley sighed, gave a word of advice to the riders around him, and then turned back into the hall.

There were not many insects left in the hall, and several knights flew to kill the last group of adults, many of whom had already come in to clean the scene, and piles of insect corpses were bagged and transported to the outside by them.

In front of the central pillar, Hermione's team was inspecting the inside of the magic pool, and it didn't seem like a big deal, as they were filling it with magic stones.

"When will it start?" the Black Knight walked over to the alchemist's side.

"Right now!" Hermione said, walking to the eastern wall, reaching into the hollowed-out ring structure with her left hand, and flipped the switch in it.

- Wow!

The silver ring embedded in the wall immediately began to rotate, and the female alchemist withdrew her right hand, watching the silver ring with a nervous expression, until a thin layer of electric light swirled around the surface of the ring, and her expression relaxed:

"That's it!"

As soon as she finished speaking, her hair stood straight up, not just Hermione, but everyone in the hall with their heads straight up.

The situation on Yalei's body is even more severe, not only is his head upside down, but there are also dense electric sparks on his clothes, and there is a faint smell of mush......

What is the situation!

The alchemist's lips tilted upward, he smiled, and muttered in a low voice: "Don't worry, this is a normal mana rejection reaction, if you don't want to run, you'd better get out quickly." ”

"Successful ......" The black knight asked halfway through, his sleeves suddenly crackled and began to spontaneously combust, and he quickly flashed out of the door, and waited for the arc on his body to disappear before continuing to ask:

"Did it succeed? Are you sure the barrier's defense is aimed underground?"

"Don't worry!" Hermione cocked her chin and gave a confident thumbs up, indicating that it was perfectly fine.

Yalei replied with the same gesture, praised her, smiled at each other, and walked down the steps back to the vestibule.

"Finished cleaning up the bugs?" Bruno saw him coming over and pointed to the rows of third-order knights behind him: "According to your request, I have already singled everyone out, what are you going to do?"

"It depends...... It's getting closer!" The black knight's index finger drooped, and his gaze moved to the ground with his fingers: "You should be able to feel it too......?"

"Quantity...... It seems like a lot. The Silver Knight frowned, feeling the ground tremble more clearly, and a trace of fear passed through his heart.

"Don't worry, Hermione's defensive barrier is working. Jarley passed him by, walked over to the three rows of knights selected by the brush, glanced at the unfamiliar faces, and raised his voice to a loudness they could hear:

"Every one of you must feel the movement coming from the depths of the earth. Even I don't know what will happen in a few minutes...... But at this moment, you should know how heavy the mission is. ”

He paused, carefully observing the expressions on each face, making sure they were more excited than afraid. After the morale was available, he sincerely continued:

"Come with me and do what we are supposed to do. ”

With that, the Black Knight took the lead towards the stone staircase leading to the boulder wall, and the knights hesitated for less than a second before mustering up their courage and following him.

After the highest combat power of the third district climbed the boulder wall, the clearer the vibration of the ground became, and the stones on the ground that were not at all conspicuous began to shake slightly, at this time, not only the knights, but also ordinary people could feel the movement of the earth.

"What's going on, is there going to be an earthquake?"

"It's not an earthquake! Something underground, something underground, it's going to come out!"

"Why don't you let us retreat! Is this going to kill us?"

Hearing that some people in the vestibule were actually resentful, Yalei was suddenly furious, and finally suppressed his anger, and shouted at the scattered queue below:

"Scholar mage Hermione has activated a defensive enchantment in response to the mutation underground, and I'm not dead yet, why are you panicking?"

His words were ten times more effective than the knight who maintained order shouted at his throat, and the vestibule was eerily quiet.

Of course, no one dared to make noise anymore, and from the other party's words, it was obvious that it was to protect their safety. Most of the people quickly settled down and regained their composure, and the few people who were frightened did not dare to talk nonsense.

"An unknown catastrophe is just around the corner, what we need is unity, I will not leave anyone behind, and I will not allow you to leave anyone behind!"

The Black Knight condescendingly pointed to the ground and gave a series of commands:

"All the students who can use spells are out of the ranks, all the knights are out of the ranks, and those who are incapable are immediately back in the library. ”

"Kara, you pick out ten second-order knights and guard against a qiē mutation in the library. ”

"Hermione is in charge of maintaining the stability of the defensive barrier, ready to switch modes at any time at my command. ”

......

One order after another was carried out in an orderly manner, and the vestibule quickly restored order, and most of the first- and second-order knights were mixed into a phalanx and waited at the exit. Each mage arranged several (first-order) knights as escorts, and climbed to the top of the boulder wall, shivering in the cold wind as they waited for fate.

No one wonders about their tables...... After all, the number of mages who specialize in combat is too small, so it is estimated that a group of people who have been soaking in the real room all day long will have to hesitate for a long time to suddenly kill a chicken, let alone actually enter the battle.

Many of the less experienced first-order knights also looked like they were not much worse, and they hadn't done anything yet, all of them were panting nervously, looking like they were about to drown in the air.

In this group of mages with genuine miscellaneous cards, Yalei saw a familiar figure...... The slightly curled show like snow flocculent, the thin and slender body, the crystal clear snow-white skin, and the sapphire-like eyes - it is Elena who was pulled up as a strong man!

The Snow Maiden wears earmuffs on both sides of her head, a plush scarf around her neck, a tight leather coat on her upper body, and long leather pants on her lower body.

Seeing that the black knight looked at herself a little stunned, she blinked mischievously, and then deliberately put on a straight face, pretending that I didn't know you.

Grunt...... Grunt...... Rumble——!

The ground around the library, like a lake blown by the wind, suddenly rippled, and the amplitude became larger and larger! The earth rolled and sprayed a large amount of sand and gravel, wave after wave, and the sky was stirred up to a gray yellow, mixed with strange grinding sounds, and spread wildly towards the library.

The library surrounded by boulders looks like a lonely island in the middle of a stormy sea, and it looks like it could be submerged at any moment.

Thump...... Thump......

With a series of heavy objects hitting the ground, several mage apprentices rolled their eyes and softened, and one of them, a miscellaneous mage in a sweatshirt, was still wet under him......

The knights hurriedly rushed to the first aid, but Yalei snorted coldly:

"Wake up now, leaking urine! Lift him down and wake him up, let him change his pants and come up again!"
