Most of the trees in this forest are dominated by evergreen pines and cypresses, and some tall poplars are interspersed with them, but Grandpa Gu noticed that a few of these trees are different from others, with oval and slender leaves neatly arranged on both sides of the branches, and strings of small red flowers hanging at the tips of the branches.

"This is the Oni Locust?" Obviously, Wang Siyang also saw that something was wrong.

"This is the blood locust." Grandpa Gu measured the distance between the trees with his feet, and looked at the general direction: "The ghost locust attracts ghosts but does not hide yin, but will release the yin qi, and this blood locust is just the opposite, it will hide and collect all the yin qi and resentment around it and supply it to the ghosts and monsters to cultivate, but not all ghosts are qualified to use the blood locust." ”

Grandpa Gu faintly felt that this was not right, this blood locust seemed to have been growing here for some years, and it was not planted more than ten years ago, how could there be such a coincidence, it just so happened that this place had become a place for ghost cultivation, this was clearly a yin array, could it be that there was really someone behind the scenes who was manipulating all this, if so, this game of chess would be a bit big.

"Grandpa Gu, look." Wang Siyang seemed to have discovered something and called out to Grandpa Gu.

Grandpa Gu quickly stepped forward to Wang Siyang's side, and found that a layer of white powdery things appeared on the ground under a blood locust tree in front of Wang Siyang, squatted down and grabbed a handful, carefully rubbed it with his hands, and then took it to his nose and sniffed it gently, it was lime.

Sure enough, this place itself is like a tomb, since it is a tomb, of course there will be nothing on the ground, plus the blood locust gathering yin array, you can hide the grievances and souls of all the dead people underground, although the lime gathers yin, but it can also block yin and yang, the lime here just plays a role in preventing the exposure of yin qi, the people who do these things are very thoughtful, they are afraid of being discovered, but no matter how precise the layout is, there will be a time when people find flaws.

"Is there a basement in the administrative building?" Grandpa Gu asked the two security guards, obviously at a loss for what to ask, the two glanced at each other and shook their heads in unison.

"Is it not or do you not know?" Wang Siyang interjected impatiently.

"This mage, we're newcomers, we don't know what is in this school." A security guard spoke Mandarin with a strong dialect and said innocently.

Wang Siyang slapped his head, he made a mistake, he made a mistake, he should let Principal Zhang leave a person who is familiar with the campus environment, and he saw that these two were only stupid in addition to being strong.

Without Grandpa Gu's explanation, Wang Siyang quickly took out his mobile phone and called Principal Zhang, but after a minute or two, Wang Siyang hung up the phone and nodded firmly at Grandpa Gu: "Principal Zhang said that the basement is full of abandoned tables, chairs, benches and some sundries that have not had time to be disposed of, and he has now sent someone to deliver the key and asked us to wait for a while." ”

"No need to wait." Grandpa Gu didn't say a word, and took the lead towards the administrative building.

Wang Siyang slandered: "It's all handsome, it's as if you can find the basement without being brought by someone." Although he was a little dissatisfied, he still called two security guards to follow.

As expected, Grandpa Gu coolly thought that he could find the basement smoothly when he entered the building, but he didn't expect to be disappointed, except for the hall that entered the door, there were classrooms on the left and right sides of the first floor, and there was nothing special to look at, Grandpa Gu thought that there would be a special passage in the basement, or marked or something, it was really nothing.

Wang Siyang covered his mouth and snickered, how much he wanted to laugh at Grandpa Gu at this time, but Grandpa Gu didn't give him this opportunity, took out a paper-cut shaped like a puppy from his waist bag, and used cinnabar to point two small red dots on the position of the eyes, and then bit his index finger to drop the blood on the dog's mouth, ready, he put the paper-cut on the ground, silently recited the incantation in his mouth, and the paper-cut slowly stood up by himself.

"Come out, Yin Detective Dog Zhao Gangzhu!" After the last mantra was recited, Grandpa Gu suddenly shouted and put on a very middle two pose, and the three people present were stunned, and the scene was very embarrassing again.

Grandpa Gu then remembered that Gu Jiu was not around.

deliberately cleared his throat, Grandpa Gu pretended that nothing had happened, and threw a big bone to the curly-haired little white dog in front of him, the little white dog gritted his teeth, wagged his tail at Grandpa Gu, and barked twice before picking up the bone.

The two security guards found that the paper-cut puppy kept jumping on the ground, because the two of them were neither yin and yang eyes, nor did they have the eyes of the sky, so they could only see the paper-cut and could not see the dog spirit attached to the body and the paper-cut. But even so, it was enough for them to be amazed for a while, and they all stretched out their thumbs: "I mage the mage, you are really amazing, our brothers have opened their eyes today." ”

"Yes, but I'm too ugly with this dog." Wang Siyang said with the accent of the security guard, stretched out his hand to tease the little white dog, not wanting to almost let the little white dog bite off his finger.

"Don't speak ill of it, it understands it." The little white dog floated into the air, stretched out its pink little tongue and licked Grandpa Gu, who patted its head gently: "Zhao Gangzhu, work." ”

Zhao Gangzhu, the yin probing dog spirit, listened to Grandpa Gu's words, and searched obediently, constantly sniffing east and west with his nose, the appearance of a tiger's head and tiger brain is really cute. Within five minutes, Zhao Gangzhu stopped at the door of a classroom next to the toilet on the west side, and kept screaming at the door, it seemed that this was the place they were looking for.

Grandpa Gu picked up the paper-cut on the ground, wiped off the cinnabar spot at the dog's eye with his hand, and the paper-cut was instantly burned into paper ashes, and Wang Siyang saw Zhao Gangzhu holding the bone and slowly disappearing.

A few people came to the door of the classroom, Grandpa Gu repeated his old tricks, and after a while, the classroom door was opened, a very ordinary classroom, I don't feel that there is anything wrong, but there should be no students in class here, the dilapidated seats are placed quite messily, and a thick layer of dust also shows that no one has been to this classroom for a long time, it looks like this should be a utility room.

Directly behind the classroom, there is a light brown wooden door, the same size as a normal classroom door, presumably the entrance to the basement.

"It's nothing special, is Zhao Gangzhu mistaken?" Wang Siyang asked Grandpa Gu with some uncertainty.

"The Yin Detection Dog Spirit is not an ordinary dog, as long as there is the slightest trace of Yin Qi, it can sense it no matter how many walls it is." Grandpa Gu explained that if Gu Jiu was here, he would not have wasted so much energy.

Left two security guards at the door, one is to make a response, the other is that no one knows what the situation is below, that is, the heavy yin gas below, ordinary people can't stand it, inhaling too much yin qi will lie in bed for a few months if you get sick, and if it is serious, you can die on the spot if you are weak, and the two don't want to implicate innocent people and let them be in danger.

Although the two were very curious, they heard the mage say that this trip was dangerous, and immediately dispelled the idea of going with them.

I checked the equipment I carried again, and after confirming that it was correct, the two entered the door one after another, there was no ghost story at all, it was long and dark, and I couldn't see the terrifying corridor with five fingers, and there was a light switch next to the door, and after pressing it, the incandescent light suddenly lit up, and suddenly illuminated everything in front of me, not far behind the door was the staircase leading to the underground, which didn't look steep at all, it should be for the convenience of carrying things, the two held their breath, no one spoke, and continued to walk down.

When they arrived in the basement, the two of them were taken aback, thinking that the basement should be a particularly large space, or that there were many rooms, but here it was only the size of a basketball court, and the waste tables and chairs were full of piles.

Grandpa Gu will have no bottom in his heart, it can't be that Zhao Gangzhu is mistaken.

I didn't give up and looked around, but I couldn't find anything after turning around, and after a careful search, it was still the same result as before.

"Pong." When Grandpa Gu turned around, he accidentally bumped into a chair placed in the corner, and the chair fell backwards and hit the wall.

Both of them stopped their movements at the same time, and both noticed the unusual sound, the sound of the collision was obviously not the sound of smashing against a solid wall, but more like hitting an iron door.

Quickly peel off the old tables and chairs, and see that there is an iron door with the same color as the wall in the corner of the wall, no wonder the two of them have been looking for a long time and have not found anything, if they don't happen to bump into each other, I'm afraid the two are still busy now.

"Damn, it seems to be welded to death, what should I do?" Wang Siyang knocked on the iron door, the back was indeed empty, but it couldn't be opened, so he could only watch dryly.

It's all come to this point, what can I do: "You go and ask someone to send a cutter and cut the door open."

"I thought you had something to do with that."

"What nonsense, hurry up." Grandpa Gu said impatiently, knowing that Wang Siyang was deliberately teasing him.

Wang Siyang took the order and quickly ran back upstairs. Half an hour later, a few people who seemed to be migrant workers carried a slightly larger cutter and walked down, connected the electricity and started it in one go, and cut the completely welded iron door in a short time.

"Principal Zhang said that there is an air-raid shelter underneath, and because it does not affect the construction of the building, it is not landfilled." When I went up to call Principal Zhang to ask for a cutter just now, I asked in detail about the situation here.

Grandpa Gu stared at the rich yin qi oozing out of the crack in the door, and his expression was solemn.

"Get ready, we're going down." took out the avoidance talisman in the bag, pasted it on the back of the chest respectively, and held the copper coin sword tightly in his hand, Wang Siyang also pasted a few spirit talismans on his body according to Grandpa Gu's appearance, took out the peachwood sword in the bag, and waved it twice.

Pushing open the thick iron door, the two of them stepped into the door one after the other, not as lit as in the basement, Wang Siyang always felt that from this moment on, it was a bit like the one written in the novel and full of eerie atmosphere.
