The blister let out a piercing scream and burst open at As's feet. The milky white mist began to gurgle out from under As's shoes like a spring.

Ace didn't seem surprised at all when he knew this was going to happen, but ran forward at a faster pace. He suddenly overtook Catherine and Feeley, who were running ahead, and became the leader.

I saw Ace swing a big round axe and split a resident in front of him who had just slowly gotten up. Although the large round axe is not easy to use, it is indeed a first-class weapon used to open the way. The chaotic puppet residents, no one of whom could withstand the heavy blow of As's round axe, were beaten to pieces. So, the deputy head of the regiment, who was carrying two small "wheels", unbelievably cleared a way through the dense puppets.

Catherine and Feeley, who were following behind As, seemed relatively relaxed, and they still had time to look back at the scene behind them. A thick milk-like fog covered everything behind them. The four sides were white and could not see the five fingers, and the sound of fighting came from time to time in the fog.

"Captain, huh, is this the legendary artificial fog spirit?" Ferry ran straight and panted, "I have heard that the fog spirit produced by the Royal Academy is rationed to the military, huh, the effect is really extraordinary." ”

The Mist Spirit was originally a rare and peculiar creature in the Lake District. They are not capable of attacking, and their lives are fragile. For example, with a heavy kick from As, the fog spirit can be trampled to death like a bubble. Since fog spirits consume a large amount of dense fog during their lifetime, the fog stored in their bodies will be released after death, causing the nearby area to be surrounded by fog.

This property of the fog spirit was first discovered by adventurers. Therefore, adventurers often use the fog spirit as a tool for escape and concealment. However, the fog spirits in nature have quite harsh living conditions, and after getting out of the dense fog in the lake area, it is like a fish leaving the water and dying in less than a few hours. Coupled with the fact that fog spirits themselves are extremely difficult to capture, they usually only emerge from unknown places to devour the fog when the lake area is foggy in the early morning. The fog spirits hidden in the dense fog are not visible to ordinary people. As a result, the mist spirit is not very practical.

However, in the famous battle of "Swamp of Fog", General Trick, a master tactician known as the "King of Trickery", successfully applied the fog spirit to the battlefield, and this strange creature began to enter the vision of the kingdom's military, and gradually developed into a standard tactical equipment.

"By quickly creating dense fog locally, it can effectively blind the enemy's line of sight, so as to achieve various military objectives on the battlefield. This is the revelation of the Trick King, in his military work "Magnificent Reflections", to his successors.

Of course, the fog itself is a double-edged sword, and both friend and foe will be affected. Therefore, how to make good use of the fog spirit is an important research topic for the generals of the kingdom. Whether it was for training or actual combat, the Kingdom's demand for fog spirits suddenly skyrocketed after the publication of Gorgeous Thoughts.

However, as mentioned earlier, it is too difficult to capture fog spirits from nature and provide them to the military in large quantities. So for a long time, the fog spirit was a luxury military consumable. To this end, the Royal Armaments Service has set up a special department, the Hunting Section, to train personnel to capture fog spirits.

When Catherine's teacher, the Grand Magician Quisling, was younger, for a long time, he made a living as a fog hunter in the military hunting department. And Quisling's first understanding of magic came from his experience.

However, today, the term "Fog Spirit Hunter" will only appear in history books. Thirty years ago, the Alchemy Division of the Royal Academy succeeded in creating the first artificial mist spirit in the form of magical life. After continuous experimentation and improvement of the artificial fog spirit manufacturing method, the fog spirit is now able to be mass-produced in the alchemy room.

This artificial fog spirit is far easier to survive than the fog spirit in nature, and it is also easily recognizable in form, so Ferry can recognize it at a glance.

For military use only, artificial fogging spirits are items that are regulated by the military. The method of making them is one of the important military secrets of the kingdom. Aside from the occasional artificial fog that can be purchased from the army on the black market, adventurers rarely have the opportunity to use the army's standard equipment.

Fortunately, although Quisling was always concerned about Catherine's abandonment of academic studies and her perennial adventure, he still cared about his good student. Using his position as president of the Royal Academy, Giserin custom-made a pair of earrings for Catherine.

This pair of earrings has a special effect, and inside one of them, it seals the highest level of artificial fog spirit currently used by the military. As one of the important hole cards for escape cover, Catherine has been reluctant to use it.

"The fog should be able to buy us a lot of time. Catherine watched as the fog behind her grew thicker, "Busso's alchemy room is just ahead, we have to work harder." ”

"Artificial fog spirits, since when have humans been able to create mimic magical lifeforms? "The goblin scholar has appeared in an incredible way. He floated beside Catherine and Ferry as if he were in a state of obsessed memory.

"Ah, Mr. Professor, dear Mr. Professor. Ferry greeted warmly, "Are you busy?"

But the busy goblin scholar didn't even lift his head, as if no one was talking to him at all.

"I'd like to ask you a question, and I'm sure you know. How can we get out of the gray realm, you say?" Ferry was not at all surprised by the goblin scholars' neglect. Instead, he asked in more enthusiastic words.

According to Ferry Fee's idea, the old professor, who hated the outcasts, would be happy to help them out of their predicament. As soon as his words fell, the figure of the goblin scholar slowly dimmed, as if he appeared in front of the three of them just to "write this down".

"You might as well not speak. Catherine sighed, "I remember reading about goblin scholars as a bunch of old pedants with all sorts of quirky tempers. For example, some goblin scholars like to greet each other by asking questions. If you can't answer the questions they use to greet them, they will refuse to continue the conversation with you, while other goblin scholars will never answer any questions anyone asks. Whoever dares to ask them questions, they turn away and refuse to talk. I think the old professor we met is probably the latter. You've already asked him once in the bathhouse. ”

Ferry crooked his mouth, "Captain, you have to talk about this kind of thing earlier." The soup is dry, and you told me not to be too hot. Did this work?"

"He walked twice in a row before I thought about that. Catherine spread her hands and said helplessly, "He's going to show up again, don't ask any more questions." ”

"We're back in the alchemy room. Ace, who was running ahead, suddenly stopped.

It turned out that the three of them had already rushed out of the puppet crowd and came to Busso's cabin. The unconscious residents did not turn back after them, but continued to slowly but surely move in the direction of the town entrance. Now the direction of the town entrance is still shrouded in a thick fog, and the sound of fighting from there has become more and more intense.

"It seems that Busso is not controlling them, and I hope these puppets can fend off us for a while. Catherine stepped forward and stood beside As, "That guy should be in his alchemy room."

Ace calmed his heavy breath and threw the round axe in both hands in front of him. "Boom" the heavy axe slammed into the dirt with a dull sound.

"God knows how those monsters of the Bluestone Legion threw such a heavy thing so far. Ah Si shook his hands that were a little out of strength, and only after his strength recovered a little before he picked up a round axe, "Such a heavy thing, it is probably necessary to hold it with two hands to make a few moves, otherwise you can only barely smash it." ”

"We're running out of time, we have to hurry. Catherine took a deep breath and turned back to Ferry and said, "I'll go down with As." Ferry is up to you to keep watch here. If there is any movement on the side of the Bluestone Legion, let us know immediately. ”

As a priest, Ferry did not have much combat effectiveness. All of them go to the alchemy chamber by Catherine and Ace to fight Busso.

The two entered the underground passage and carefully groped their way to the alchemy room. However, there were no obstacles in the passage, and they easily came to the alchemy room. The door of the alchemy room was hidden, and it was quiet inside.

Catherine glanced at As, and each of her hands condensed into an icy snowball. Ace nodded, and when Catherine was ready by the door, he kicked it open with a slam of his hand.

In the alchemy room, Busso stood motionless in the middle of the room. He saw the two men at the door, and rushed towards them with a strange "oh oh". Catherine fired her bow left and right, throwing two frozen snowballs over.

At such a close distance, Busso couldn't dodge at all, and was hit right by two icy snowballs. His movements immediately became sluggish and sluggish, and his whole body was covered with white frost.

Of course, Ace would not let go of such a good opportunity to attack, and the man rushed out like a cheetah. Busso's body reacted more than a beat slower, and just as he made a fist and striking, Ace had already swept the round axe, and slashed at his waist with all his might.

"When—" With a low metal thud, Busso's body was centered around his waist, showing an eerie fold in half. He slammed into the wall and fell to the ground, making a "hiss" sound in his throat. Busso's hands and feet moved irregularly, trying to get up. But his body was deformed, and his hands and feet could not work properly.

Ace wouldn't give Busso a chance to get back on his feet, he stepped forward quickly and threw an axe at Busso's neck. Catherine subconsciously turned her face sideways to avoid the image. However, the imaginary blood did not spurt out of Busso's neck after his head moved.

On the cut of Busso's neck, only a small amount of dark red liquid flowed out. His head rolled on the ground and hit the box furnace in the alchemy room before stopping.

And so the battle ended.

Both Catherine and Ace felt that the battle seemed too simplistic, and that the semi-metallic Busso should show more power to fight against each other. And when he entered the door just now, how could this guy stand in the alchemy room in a daze?

Catherine carefully examined the alchemist's furnace, but she didn't see anything that had been done with it. "If you burn like this for another hundred years, it will not explode", is the conclusion that Catherine has reached.

Now the two of them feel more and more strange, what is wrong?

"How so?" Asso, picking up Busso's head and placing it on the large wooden table by the door. He said solemnly to the head, "Dude, what is your idea, do you want to blow up this place?"

"What is your idea, why did you come to my alchemy room?" asked Busso as he opened his eyes suddenly.

Ace was taken aback, but he wouldn't be afraid of a head with only one mouth left. He tapped on half of Busso's metal cheek and said, "Because we don't come, you're going to blow us up and the town into the sky." ”

"Why should I detonate my alchemy room?" Busso's expression was dull, his eyes were two black holes without a look, and his upper and lower lips only opened and closed mechanically.

"It's your business, you shouldn't ask me. Ace had a headache, and he gave up his seat at the table, "Catherine, it's better for you to deal with this thing." Magic and stuff, you're an expert. ”

"I'm not very good at alchemy, at least I can't refine my head to the point where I can still speak without my body. Catherine walked over to the table and carefully examined Busso's head.

"Do I look like a king?" asked Busso again.

"It's not like, it's just like that. If it weren't for that half-metal face, I would have thought you were His Majesty. Catherine simply picked up Busso's head and looked at it over and over. This thing was completely beyond the scope of her cognition, and it aroused the female mage's strong desire to study.

"Are you going to kill me just because I look the same as the king?"

"It's not that we're going to kill you, although we did kill you, we didn't actually kill you. What happened here was an accident, and we killed you to stop you from detonating the alchemy chamber. Catherine replied absent-mindedly.

"Catherine, I think you'd better think about it before answering. Ace shook his head and laughed.

"Well, I don't even know what I'm talking about. In short, it is His Majesty the King who really wants your life. Catherine stared at the incision in Busso's neck, "You can say a few more words, how do you make sounds without vocal cords?"

"Why did the king kill me?" Busso's mouth opened and closed, and the voice came out inexplicably.

"The head of an alchemist who can still speak when he leaves his body, this should be written down. The figure of the goblin scholar gradually appeared on the wooden table. But this time he had just written two words before hesitantly stopped.

"Do you want to write this down?" the goblin scholar walked over to the table, thinking as he looked at the Busso head in Catherine's hand.

Catherine raised her head flat and handed it to the goblin scholar. The old professor seemed to frown, and he stretched out a short, white mist finger and inserted it directly into Busso's mouth.

"Female mage, you answer his question. The goblin scholar said in the tone of a teacher to a student.
