Since Feng Xing had said so, Zhang Longqian put his mind at ease and sat down against the dry cave wall, while calming her disordered breathing, she looked up and looked around.

Obviously there is no light source, but it is only a little dim here, and everything around can be seen clearly, but what catches your eye is just a very simple cave, there is nothing in it, it is empty, and the entrance and exit are only the one covered with thick fog, but the yin qi here is much less than outside, and the chill is also a little less, which makes Zhang Long's body that is about to freeze under the yin qi feel a little better. The whole cave is no more than three meters high, the length and width are ten meters or so, the cave wall is very flat, it does not seem to be a natural formation, but there is no artificial trace, shallow nicks are covered with the roof and the wall of the cave, it seems to be a huge and complex pattern, too dim Zhang Longqian can't see clearly, but it feels that there seems to be some kind of spiritual power between the lines, and the operation of the previous nine seals seems to be somewhat similar.

What is this place?

Zhang Longqian, who was a little curious, turned his head and wanted to ask Feng Xing, but saw that he was also looking up at the patterns in the cave, but the expression on his face was not confident and uninhibited that could always be seen, but a complicated look that made people feel a little distressed.

After all, he has a peculiar connection with Fengxing, and Zhang Longqian felt a little empathy when he saw his expression, and the uncomfortable feeling made her dispel the idea of asking Fengxing, and just looked at him silently, quietly staring at the little ripples in those dark blue eyes.

After a while, Feng Xing still didn't look at Zhang Longqian, just floated to the cave wall on the other side, raised his hand to touch the lines on it, but his fingers passed through it as if he was sinking into the water, and nothing was touched, which made him stiffen slightly, and then turned his head away, hiding his expression in the shadows.

But Zhang Longqian did not miss the pain that appeared in his eyes at that moment.

Countless kinds of speculations passed through his mind, but he couldn't ask any of them, and Zhang Longqian, who didn't know what to say, could only look at Feng Xing silently, and his eyebrows were squeezed out of worry.

As if sensing Zhang Longqian's gaze, Feng Xing took a slight breath and said in an ordinary voice: "This is a hidden place built to help students who are not strong enough to avoid ghosts in the spiritual research, and the magic circle is depicted on it, which can only be opened with nine seals, and once entered, all breath can be completely erased, and ghosts will definitely not be found." ”

Hearing Feng Xing take the initiative to mention things related to this cave as if he was fine, the worry in Zhang Longqian's eyes couldn't help but be stronger, but since Feng Xing used this to show that he was fine, she couldn't say anything, so she could only pretend that she hadn't noticed anything, and followed his words.

"Uh...... So, are we just here waiting for the ghosts outside to disperse? Ah, why don't you ask the teacher to get me out now? ”

Feng Xing shook his head and denied: "It's useless to call them now, you can't communicate with the outside world here, wait for the ghosts to decrease before you go out and call them." ”

"Oh" nodded, Zhang Longqian said again: "But I really didn't expect that the evil ghost of Abi Hell is different from other evil ghosts, and looks like a human being......

"This is the 'common sense' of the world, just like the demon cultivation also needs to transform into a human form at the end, if the evil ghost reaches a certain level, it will naturally change back to the human form before death, so as to continue to break through."

"But demons stay in hell, right? Will they be given a chance to break through there? ”

"No, before that you will be stripped of your evil rosary and thrown into reincarnation."

Thinking that this was the case, Zhang Longqian nodded slightly.

Although it was only a glance at the face, those deep eyes had already left a deep impression on Zhang Longqian, unlike any ghost she had ever seen, there was no anger in those eyes, nor was there a little confusion, but a calm and calm that ordinary people rarely had, if it weren't for Feng Xing's warning, it would never have been imagined that he would be a demon.

Recalling the face of the evil ghost she saw in a hurry, Zhang Longqian's mind saw a dignified and resolute face, but it gradually overlapped with another extremely god-like face in her memory, her eyes widened for a moment, and she couldn't help but let out an "ah".

“…… It's white! ”

Although it is not exactly the same, there is no doubt that that face is the Bai Qi that Zhang Longqian once saw in the illusion of history class, the Wu Anjun Bai Qi who ordered the killing of 400,000 Zhao prisoners of war in the Battle of Changping.

"Wu Anjun?" Feng Xing, who was facing away from Zhang Longqian, paused, then nodded, as if he was not surprised, "No wonder...... If it were him, it would be normal to become a thousand-year-old demon. ”

Although Zhang Longqian didn't understand how the evil ghost cultivated, she agreed with Feng Xing's words very much.

Thinking about it, Bai Qi has been dead for more than 2,000 years, and such a great killing god has been in the Abi Hell for so long, it would be strange if he didn't become a powerful evil ghost, right?

Thinking without any objection, the topic ended there, and silence returned to the cavern.

The heavy atmosphere that had finally faded between words gradually recovered, looking at Feng Xing's somewhat translucent back, Zhang Longqian remembered the pain in his eyes when he looked at the magic circles around him, and his mood became heavy again, and she couldn't find anything to say for a while, she could only stare at Feng Xing, and secretly guessed all kinds of things that might be related to Feng Xing.

It seemed that he finally couldn't stand such silence, Feng Xing sighed softly, and then turned around and walked to Zhang Longqian's side, looking at her condescendingly, with the usual impatience on his face.

"Okay, if you have anything to say, just say it, it's awkward, it's annoying."

Zhang Long subconsciously shrunk his neck and muttered in a low voice: "I'm afraid that you will be more upset if you say it......"

couldn't help but sigh, Feng Xing sat down directly opposite Zhang Longqian, and looked at her with a frown: "Just ask whatever you want." ”

"But ......"

"It's okay, just say it. I haven't used it to worry about you. ”

Seeing Fengxing's resolute attitude, Zhang Longqian, who couldn't resist him, could only sigh secretly, and then slowly spoke in a careful tone.

"That...... Big brother, have you also been in the academy? ”

Then she received an idiot-like look.

"Since a thousand years ago, there has been only one academy in the entire Dao Law Realm, and all the people who study spells have gathered here, what do you think?"

I didn't expect the academy to have such a long history, Zhang Longqian couldn't help blinking unexpectedly, and said, "I see", then thought about it, and finally asked softly: "So big brother, you are here...... Looks familiar? ”

For a moment, he seemed to freeze, and then Fengxing nodded slightly.

"Not only that, but also because I participated in the construction of this place, all the magic circles here...... I carved it all with my own hands. ”
