Artoria slowly opened her eyes, surveying her surroundings in confusion.

Her last memory is that after she promised Charles, she was taken to a gray space by Charles with a wave of her sleeves, and she fell into a coma as soon as she arrived.

Thinking of what Charles had said to him before he promised him, the confusion in Artoria's eyes suddenly dissipated, and she hurriedly glanced around to find Charles's figure, and found that the other party was standing behind her.

"Teacher Charles!"

"Toria, I know what you're asking, what I'm telling you is true, if you don't believe it, just look at the environment you're in now."

Artoria looked up at the words, and it was then that she realized that she was in an environment that she had never seen before.

Even though it was dark all around, Artoria's blood allowed her to see everything around her clearly.

There was a rock formation above her, a swarthy rock that rose above her head to cover everything, and as far as Artoria could see, nothing else could be seen.

"We're in an underground cavern?"

"Yes and no." Charles shook his head slowly, "Because this is indeed an underground world, but its area is completely immeasurable, far more than the world you were in before, it can be said that this is a plane, but there is an underground environment. ”

Artoria looked around in amazement, and when she looked around and saw that they were plants she had never heard of, she began to believe what Charles had told her before she fell unconscious.

"Teacher, are we in the world you said we were in now" Artoria still wanted to make sure again, her eyes fixed on the expression on Charles's face, she was afraid that the answer would disappoint her.

Artoria's obvious performance Charles naturally would not be unaware, but he also knew that in the girl's heart, the destruction of the kingdom he had sworn to protect in his own hands had become her biggest obsession, and even became a magic barrier, otherwise Charles thought that he might not have any chance to touch the girl's pure and immaculate soul.

"Yes, Tolia, this is another world, where there are powerful opponents, warriors with excellent physical fitness, and mysterious mages, where you can hone your strength and then go back and change the ending that you regret."

Halfway through speaking, Charles had a look of embarrassment on his face, and Artoria, who was staring at him preoccupiedly, found out and hurriedly asked what was wrong.

"That," Charles hesitated for a moment before he said guiltily, "Tolia, I think I have to tell you about this, you know, I was attacked by a demon who suddenly appeared, and I disappeared at the time of the final battle and couldn't help you, and it was also because I tracked the breath left by the other party to discover this world, than relying on the mark left on the other party's body, taking you through this world." ”

Artoria nodded, she could hear the guilt in Charles's words, but Artoria didn't care at all that her most trusted teacher didn't show up for her when she needed help the most.

"Teacher, the legend of the devil has been circulating in the world, even if I haven't seen it, but just relying on the description in the myth and legend, I know that the other party should not be underestimated, teacher, you can survive the devil's attack, I am very happy, teacher, you don't have to feel guilty. Teacher, let's continue to talk about the rest of the matter, what the hell is going on? ”

"I don't know if Artoria, you've noticed something wrong with your soul." The guilt on Charles' face became deeper when he said this, "Maybe it's because I relied on the remnants of the devil's breath to travel into this world, and I found that I and your soul are wrapped around a little devil's breath, and in the past few days, I have tried countless methods, but I can't completely eliminate this breath, as if I have completely merged with my soul and are inseparable." ”

Artoria was stunned for a moment, and hurriedly examined her soul, and sure enough, there was a pitch-black impurity firmly attached to her soul in the depths of her soul, and as soon as she had the idea to expel this impurity, a pain that penetrated her soul spread throughout her body, making her unable to suppress it, and let out a soft snort from between her teeth.

Charles hurriedly stepped forward to support the girl's body, which had almost fallen due to pain, and looked at the gloomy expression on the girl's face with guilt and worry in his eyes.

Noticing the feelings contained in Charles's gaze on her, Artoria was slightly stunned, and only then did she react in her heart, I am afraid that I have become like this, and the most uncomfortable thing is my teacher.

This teacher has been extremely pampered since he was a child, and outsiders absolutely can't believe it, and Master Charles, the sage of the empire, who has always maintained a gentle expression in front of everyone but rejects people thousands of miles away, has a doting expression on his face when he is in front of him, and will always respond to any request he has, and then devote himself wholeheartedly to helping himself to look at it, and solve the problems he ignores in obscurity behind him.

And now, because he is entangled in the breath of the devil, his soul is polluted by the devil, and the teacher is already guilty because he didn't help himself in the final battle, and I'm afraid that he has regretted it at this time, and feels even more sorry for himself.

"Teacher, I'm fine, isn't it just a little impurity, it won't affect me." Artoria hurriedly put away the expression on her face and opened her mouth to comfort Charles, but she knew, and Charles also understood, that the soul was polluted by the devil, and it would never be as easy as she said.

Charles didn't speak, and after Artoria stood firm, he withdrew his hand, looking like he was probing the surrounding situation, but Artoria, who was standing beside Charles, could clearly see guilt and gloom flashing in Charles's eyes from time to time.

This caused the girl to stop paying attention to the problems of her soul, but silently walked up to her teacher and looked up at her surroundings.

"Teacher, since we have arrived here, how can we improve our strength?"

The girl cleverly avoided the soul and asked about her next plan.

Charles groaned slightly, and after scanning the surroundings, he stretched out his hand and pointed in a direction, "In the past few days when you have been unconscious, I have probed around and found an underground city in this direction, but because the guard force on the other party's city wall is very sufficient, I don't dare to rush in to investigate." ”

Charles suddenly turned his head to look at Artoria, and under the girl's puzzled gaze, he said, "Artoria, when we get to that underground city later, don't be too surprised by what you see. ”

When the girl followed Charles to an underground city full of doubts, she understood why her teacher told her not to be too surprised by what she saw, because most of what she saw before her exceeded what she had seen and heard, and it challenged her common sense.
