Mu Yunjun didn't expect that these teenagers who were about the same age as himself could still see so many ways.

She knew what the concept of the ghost general level was, and Xiao Hei and the ghost old man of her family had also popularized the level of ghost cultivation to her. The new ghosts are all within ten years after their deaths, and after ten years, they are at the level of ghosts, and after the level of ghosts, there are old ghosts, ghosts, ghost generals, ghost kings, ghost ancestors, and ghost immortals (ghosts).

Becoming a ghost is generally within fifty years, and the old ghost level is a ghost path cultivation that does not exceed a hundred years within a hundred years. and then to the ghost level, there are ghosts from a hundred to three hundred years like the old man of her family, most of whom are from the Qing Dynasty. The ghost general and the ghost king are three hundred to one thousand years old and one thousand to three thousand years old respectively, and the ghost ancestors are all above three thousand years old.

Ghosts and demons are at the same level, but they are only divided into righteous paths and demonic paths. But basically, they are all prominent titles.

So after Mu Yunjun listened to their words, what he learned was that there was not only a new ghost here who didn't know that he was dead, but also shouted every day, 'Let me out, it hurts, it's so ......black', and there was also a ghost general-level ghost who had been cultivated for hundreds of years.

However, she didn't understand what the Prisoner Ghost Array and the Yin Refining Array were, and she didn't feel the existence of another Yin Qi.

- If what they say is true, then you can't feel the yin energy of this ghost general, probably because the other party is sleeping now. If it's awake, then you'll be able to sense its presence.

At this time, Xiao Hei slipped out and said a word to her.

Mu Yunjun turned into a ghost and stalked in the darkness, slowly moving back towards her dormitory.

She asked: - What are the Prison Ghost Array and the Yin Refining Array?

Xiao Hei thought for a while and said: - The ghost prison array is an ordinary ghost suppression formation, which simply imprisons ghosts in one place. Most ghost-hunters do. The Yin Refining Array is several times more advanced than the Imprisoned Ghost Array, because part of it is also formed by the Imprisoned Ghost Array. Generally speaking, it is a large array composed of several small formations such as the Prisoner Ghost Array, the Soul Extraction Array, the Soul Refining Array, and the Yin Gathering Array. The most critical point is that this formation is relatively vicious, and it needs to extract the souls of living people as sacrifices. Then erase the living soul's memory of death and make it think it's still alive. Maintain its soul power with the obsession of living, so that the other ghost can absorb its soul power to nourish itself.

When Mu Yunjun heard this, this was indeed a vicious formation.

Xiao Hei continued: - In general, this formation is generally not used by decent people, and it is not easy to arrange. After all, several formations are formed, and if there is a slight mistake, the entire formation will be destroyed. Generally, this formation is used, which means that the ghost who has been warmed up needs to be healed. Therefore, this formation is listed as a forbidden technique by the righteous path, and it is also forbidden for others to use it, and anyone who uses it will be punished.

At this time, Mu Yunjun thought of a question: - You mean, this formation is to use the soul of a living person to heal another ghost, so this formation should have been arranged by a third person, right?

Xiao Hei nodded: - That's right.

Mu Yunjun suddenly felt that there were some dangerous people hiding in the shadows in this school.

If you are not familiar with this school, you can control the operation of this school. So how could it be possible to set up such a difficult big array here? This is also something that requires a lot of action.

She returned to the back of the dormitory, slipped through the window, and quickly returned to her dorm. As a result, the door was pushed open......

"Click~" The door is stuck, which means that someone has bolted it behind the door.

Mu Yunjun: "......" feelings, was she locked out in the middle of the night?

Who is it that you bolt the door? Didn't you see her bed empty?

Mu Yunjun didn't leave for a long time, only ten minutes at most. Generally, if someone gets up at night in the dormitory, they will come back to see if the other people in the bed are not there, and they will bolt the door when they are all back, otherwise they will just close it and not bolt it. When the last person comes in, it will be bolted.

Could it be that someone got up blurry and didn't notice her bed?

Although Mu Yunjun was a little confused, he could only ask Xiao Hei to help.

- Quick, go in and open the door for me.

Xiao Hei turned into a black gas and got through the crack in the door, and then wrapped around the deadbolt and pulled.

Mu Yunjun pushed open the door and walked in softly, while observing everyone's beds, and bolted the door after confirming that they were all there.

When she walked past Tang Mi's door, her eyes paid attention to Tang Mi's shoes, and then she walked back to her bed as if nothing happened.

Before she goes out, she will check the situation in the room. Looking at it now, there is nothing unusual about other people's beds, only Tang Mi's shoes are placed in different positions. Therefore, in the ten minutes she went out, Tang Mi got up.

Now I guess I'm pretending to be asleep.

When chatting with the instructors for the last time tonight, Tang Mi's gaze was tried her best to hide it. But he couldn't stand Mu Yunjun's extraordinary insight, and he had already noticed that she was looking at her a little strangely.

After dawn the next day, Tang Mi woke up early in the morning. Seeing that the others had not woken up, she went out to wash.

When he came back, he seemed to think of something, and secretly glanced back at the deadbolt, and then a dark light flashed in his eyes.

After she changed her clothes, she turned around and went out.

"Bang-" sound, and the door closed very loudly.

"Hmm...... Who, the voice is so loud in the morning......" Everyone who was still sleeping on the bed turned over, and Ouyang Ting couldn't help but scold with a burst of anger.

I hate this kind of person the most, when others are still sleeping in the dormitory, they make a lot of noise. The quality cultivation is really poor!

There are several kinds of people who are most hated in the dormitory. I don't care about others, I do my own, and my voice is very loud, and I don't care if others are sleeping or studying. There is also a kind of use that likes to rub other people's things, shampoo, shower gel, this use, that use. At first, I will ask politely twice, and then I won't ask, and I will use it directly, as if it were my own thing. The last type is the internal thief, who secretly takes other people's better things, pretends not to know, and even steals money. Or they like to let others bring food, but don't give money.

After Mao Ningning heard Ouyang Ting's words, she opened her confused eyes and looked up at Tang Mi's bed, then closed her eyes and continued to sleep.

Mu Yunjun's eyes moved, but he couldn't open them successfully. I rolled over and went back to sleep.

However, Gu Xiaomin got up at this time, squinting his eyes, "Ah...... Well...... Sizzle...... "bump here, bump there, take something to wash your face." Although the collision was painful, she still subconsciously suppressed her scream. After a few bumps, I finally came to my senses.
