"This, okay." Liu Lao hesitated for a moment before saying.

In fact, Liu Lao still didn't believe in the theory of ghosts and gods, after all, decades of education were like this, but what happened now made him have to doubt what he had learned in the past.

After separating from Liu Lao, Lu Bao returned home and prepared some things to catch ghosts, talismans and containers are indispensable, of course, if he still has a demon umbrella at the last moment.

After getting ready, Lu Bao and Liu Lao came to Liu Lao's house, and it was already evening at this time.

"Lao Liu, are you back? Why did you come back so late today? As soon as I entered, an old lady came over.

"Lao Yang, I'm a little delayed today, let me introduce you, this is my new student Lu Bao, Lu Bao, this is Professor Yang, and also a teacher in your school." Liu Lao introduced Lu Bao and the others.

"Hello Master!" Lu Bao hurriedly said hello.

"Hello, have you eaten?" Professor Yang asked.

"Not yet, it's not too early, just eat a little together, Lu Bao, let me tell you, Professor Yang's craftsmanship is quite good, you are here today." Liu Lao said with a smile, and he couldn't see any anxiety at all.

Lu Bao also expressed his understanding of this, it should be that Liu Lao didn't want Professor Yang to worry, so he showed it so easily.

However, the movement will definitely not be too small later, and Professor Yang will know after all, but I don't know how Liu Lao will explain to Professor Yang in a while.

"You can eat by yourself, I have made an appointment with Lao Chen and them to dance today, but I don't have time to eat with you." Professor Yang waved his hand and said.

Seeing Professor Yang go back to the room to change clothes, Lu Bao gave a thumbs up to Liu Lao, this routine was slippery.

Liu Lao smiled proudly when he saw Lu Bao's movements, obviously this routine was definitely not the first time he had played it.

"The meals are on the table, you two eat, I'm out!" Professor Yang changed his clothes and went out.

"Okay, Lao Yang is out, let's start quickly." After seeing Professor Yang leave, Liu Lao said.

"Okay." Lu Bao nodded, and then took everything out of his bag.

"This is the compass?" Liu Lao looked at the compass in Lu Bao's hand and said.

"Yes, this is the compass, but, unlike those deceptions, this one is true." Lu Bao nodded and said.

Lu Bao played a magic decision, and then after the mana was injected into the compass, with Lu Bao's movements, the pointer of the compass began to rotate non-stop.

"Teacher, what is this room for?" Following the guidance of the compass, Lu Bao came to the door of a room and asked.

"This is the study, I usually read here, and the reason why I lock it is because I am worried that my little granddaughter will mess up the study when she comes to play." Liu Lao glanced at it and said.

"Can I go in and have a look?" Lu Bao asked.

"Yes, there is nothing inconvenient about this, usually I will rest here at night, it seems that I am also resting here these days." Liu Lao took the key and opened the door and said.

"The yin qi in this room is relatively heavy, but there is no special existence, which is very strange!" After Lu Bao walked around the study, he didn't find anything special except that the yin qi was relatively heavy.

"Huh? Is there anything wrong with this wall? Why does the compass always point here? Lu Bao looked at the wall behind the bookcase very strangely and said.

"There shouldn't be any problem with this wall, this bookcase hasn't been touched for seven or eight years, at most it's just a wipe when cleaning." Liu Lao said.

"Can I move this bookcase?" Lu Bao asked.

"No problem, but this bookcase is quite heavy, I'm afraid you can't move it alone, why don't I call someone to come and help?" Liu Lao thought for a while and said.

"No, I have a lot of strength." Lu Bao smiled and said.

Lu Bao believes that this compass will not go wrong, in the world of Mr. Zombie, Uncle Nine has never made a mistake in using this compass, and this compass in Lu Bao's hand has been strengthened by the farm, and it will only be more powerful.

Liu Lao was very curious about how Lu Bao moved this bookcase, how heavy this bookcase is Liu Lao couldn't be clearer, you know, this bookcase is at least thousands of catties, Liu Lao doesn't believe that one person can move it.

However, the next scene surprised Boss Liu, after Lu Bao put away the compass, he dragged the base of the bookcase with both hands, and then pressed upward, and one side of the bookcase was lifted up by Lu Bao.

"Yin Qi is emanating from this wall, and the concentration of this Yin Qi is actually so strong as you, what a lot of resentment this is." Lu Bao said after groping around the wall for a while.

"No, how can there be resentment on the wall? There must be something in the walls. Lu Bao suddenly realized something.

"Open!" Lu Bao pinched a magic decision and opened the eye of heaven.

"Such a thick resentment, such a powerful yin qi, how wronged this is." Through Tianyan, Lu Bao saw that the thick resentment and yin qi on the wall were gathered together.

"Elder Liu, I want to ask, has there been a problem with this wall recently?" Lu Bao asked.

"Questions? We haven't had any problems here, but it seems that there was a movement next door last month, so is there something wrong with this wall? Liu Lao recalled and said.

"Well, there's something wrong with this wall, and while I can't see what's inside, I'm sure there's either something unclean in here or there's a corpse hiding there." Lu Bao nodded and said.

"How is that possible?" Liu Lao said with wide eyes and an incredulous expression.

"It shouldn't be wrong, this wall has been overflowing with yin qi, and there is also resentment, it should be getting thicker and denser these days, which is why that talisman will turn into ashes overnight, if it is not solved as soon as possible, I am afraid there will be changes." Lu Bao said with a heavy face.

Lu Bao speculated that there must be a corpse hidden in it, and it was very likely that someone killed him, otherwise there would not be such a heavy grievance, depending on the degree of this grievance, it would not be long before it would become a powerful ghost.

If he did it before he became a ghost, Lu Bao might still kill the other party, but if he really became a ghost, Lu Bao himself would not have confidence, after all, his strength was still very weak.

"Wait a minute, I'll call my son back, he should have some clues." Liu Lao suddenly thought of something and said.

"Okay, the sooner this matter is resolved, the better." Lu Bao nodded and said.
