C12 Underground pipeline

"Is the function of this spell formation just a key to a hidden door?" Right now, the only problem was that he had not yet figured out what use this magical formation could have. He had memorized the magical formation and kept the paper with the drawing on it, so he decided to follow Old Xu's advice and try it out wherever he went.

"Alright, that's all we can do now. Let's wait for the people who are looking for the map to come back and see if there are any underground tunnels or abandoned factories nearby." Old Xu sat down on the chair and stretched himself lazily as he mumbled to himself.

No matter what Old Xu said, Liu Zichen continued to look around himself. Then, he memorized the formation in his heart and wondered when he would be able to draw this formation with a useful effect. Zhao Yan, on the other hand, was still standing at the doorway with his head lowered, deep in thought.

After an hour or so, someone suddenly came in and handed Zhao Yan a piece of paper while whispering something to him. Liu Zichen and Old Xu stretched out their necks to listen to what they were saying, but their voices were very soft.

After that man had finished speaking, he immediately walked out, leaving Zhao Yan behind. He looked up and said to Liu Zichen and Old Xu, "There is an anomaly in the underground tunnel south of the city, we have found a few corpses, they have been dead for more than half a month. Our men followed the previous instructions and did not go any deeper, it is already sealed off there now, should we go there to take a look?"

As soon as Old Xu heard there was a corpse, he stood up excitedly and said, "It's about time, let's go take a look."

After getting on the car, they let Zhao Yan drive. They followed the location on the map and arrived at the entrance of the underground tunnel.

After Liu Zichen got off the car, he saw some people in black suits gathered nearby, all of them had short hair, with a capable expression, holding a short stick in their hands, looking fully armed. Looking around, he felt that they were near an abandoned factory, so he asked, "This is a factory? There's an abandoned pipe underneath? "

Zhao Yan immediately waved at the person in front of him, signaling him to come over. Then, he asked what Liu Zichen had just said.

He heard the man say simply, "This used to be a chemical factory, there were oil pipelines running everywhere. There were big and small ones, but now that it's completely abandoned, all kinds of animals are gathered in the pipelines. The bodies that were just discovered have been eaten by rats or something else."

"You can't be wrong. This place is indeed very similar to the gathering of demon beasts that suck blood. Everyone should prepare in advance. Although it is daytime, those demon beasts still have basic defensive capabilities." Old Xu listened to the brief introduction and nodded his head repeatedly, indicating that this was the best place to gather the blood sucking demonic beasts.

Liu Zichen and Zhao Yan looked at each other. After seeing the affirmation in each other's eyes, Zhao Yan slowly said, "Then which pipe should we start from? If we want to go in, we can only crawl on the ground. But if we do that, won't we only be able to accept death if we meet a demon beast that absorbs blood? "

Old Xu shook his head and said, "Impossible, the demon beasts won't leave their corpses at the exit of their cave after drinking the blood. That pipe can't be the entrance to their cave, the current problem isn't how big the demon beasts are, but how big they will become in the future. You think that it won't be a problem for you to pass through a very narrow passage when you are young, but if your body is several times bigger, then you won't be able to pass through the passage. What will you do?" Would you have chosen a slightly wider passage at the very beginning? "

Zhao Yan looked surprised and asked, "Are you saying that these demon beasts are growing bigger?" How is that possible? "

"Why is that impossible? Don't put your understanding of humans and other common life forms on top of these demon beasts. What they drink is blood, and the circulatory system is very developed. Old Xu said in a nonchalant manner, as if Zhao Yan had seen too much trouble.

"Alright, Old Xu, there's no need to teach us a lesson. Tell us, where should we start the investigation? I'll just follow you." Liu Zichen quickly stood up and interrupted Old Xu, asking him what he wanted to know the most.

"I'm not sure exactly which tunnel it is, but I suggest we start by searching through the widest one, because I have a feeling that these demon beasts don't gather here on their own, and it's very likely that they were summoned here by some kind of person or creature. In that case, even if these blood sucking demon beasts are small, do you think that the creatures that summoned them are of the same size as them?" Old Xu seriously analyzed the situation.

Liu Zichen looked at Zhao Yan again and nodded at the same time to show that Old Xu was right.

"Come here and tell us about all the underground pipes in this factory. Which one is the widest one?" Zhao Yan waved to the people waiting for him in the distance again, asking him to come here and explain the situation.

"There are a lot of pipes here. If you want to find the widest one, I think the underground drainage would be okay?" "That place is pretty much like a car, isn't it wide?" The person replied respectfully.

"This is the place. Bring us there now." Old Xu said first.

Seeing that Zhao Yan nodded his head in agreement, the man immediately said, "Follow me. The underground drainage channel is near the entrance to the factory district."

He then turned around and led the others into the factory. Old Xu pulled out his short sword in excitement, while Liu Zichen and Zhao Yan walked side by side behind him.

"Don't focus only on killing demon beasts. It would be best if you could capture the person or monster that summoned the demon beasts here." Liu Zichen whispered to Zhao Yan. Zhao Yan nodded to show that he understood. At the same time, he took out a pistol from his pocket and held it in his hand.

He felt that he made a mistake by following them into the tunnel to hunt demon beasts. Firstly, Old Xu had a long dagger and felt that it was a weapon specially used to hunt demon beasts. Zhao Yan had a handgun and it seemed that his spear skills were not bad either, but the problem was that other than dealing with the soul, he did not have any other cultivation method to deal with demon beasts.

While Ye Xin was feeling conflicted, the people in front led them to an abandoned factory. They saw that the factory district was very wide, but it was filled with abandoned machines that couldn't be dismantled. The iron parts or other parts that could be removed had long been taken apart for money.

He walked forward and arrived before a door. The person in front opened it and said, "According to the factory's building blueprints, this is the entrance to the sewer. Usually, if you want to clear the blockage inside, you enter from here."

"That's enough, leave the matter here to us. Keep your brothers on guard. No matter what kind of people or monsters escape from here, arrest them if they can. If they can't do it, attack and kill them, don't let them escape." Zhao Yan nodded his head and instructed.

Liu Zichen and Zhao Yan followed closely behind. After walking up a flight of iron stairs, they descended into the underground tunnel. It was just as the man had said; it was wide enough for four or five people to walk side by side.

Old Xu continued to walk at the front with his short sword in his hand. Liu Zichen followed behind him, planning on how he should protect himself if a large number of demon beasts appeared. He opened his mouth to ask Old Xu and Zhao Yan a few questions, but was too embarrassed to ask, so he could only give up.

The few of them walked in silence, no one spoke, only the soft sound of footsteps, the atmosphere was heavy. Old Xu had not taken a few steps forward, when he suddenly stopped and listened attentively.

"What is that sound?" Liu Zichen asked softly.

"The sound of bones being chewed. If it wasn't for the sound of wild dogs, then there might have been more than one demon beast here." Old Xu heaved a long sigh, a trace of excitement on his face.

Liu Zichen's mouth twitched, then he suddenly said, "If we open fire here or cause too much noise, won't it scare away the other blood sucking demon beasts?"

"Of course, if possible, don't shoot if you don't want to. You two can just watch from behind. Let me handle this briefly. Little Liu, you should prepare yourself. If there are large scale demon beasts rushing out, you'll have to depend on your array, right?" Old Xu said with a heavy tone.

"Formation? That formation can block demon beasts? " Liu Zichen asked with some confusion.

"Nonsense, didn't you find this array on the walls of the Hu family?" "Don't think that I don't know. If they didn't summon these demon beasts, then they must have stopped these demon beasts. Prepare yourself, if there really are a large number of demon beasts attacking, then the two of us won't be able to deal with them. Old Xu said confidently, but Liu Zichen did not agree. He did not say that this formation was used to open the secret room's key.

There was Zhao Yan beside him. He did not want to reveal too much about the Hu Family to Zhao Yan, so he just agreed softly. At the same time, he was starting to doubt whether this spell formation could really stop the attacks of the demon beasts.
