Walking in the world in the sewer, your eyes are filled with cold fluorescence, the air is filled with dull smell, and all you hear is the sound of wind blowing through the pipes. In the dry canal under your feet, several animals or monsters are occasionally alarmed and run past, causing the gravel at the bottom of the canal to collide with each other and make a tiny sound. In the deep pipes in the distance, occasionally, the vague cry of monsters comes. The screams pass by the twists of countless pipes, becoming extremely strange, making people feel creepy.

"Why are there gusts of wind here?" Catherine felt the breeze and asked in confusion: "Didn't you go deep into the ground?"

"No one knows the answer." Vivian shrugged: "There are often winds in the remains of goblins, but after searching through the remains, they can't find the location for ventilation. No one knows how they did it. Therefore, this special ventilation method, like their metal alloy formula, has become one of the five unsolved mysteries of goblins in the academic world, and the first of them is the mystery of the demise of goblins."

In the breeze, there are occasionally metal friction sounds. I don’t know where the puppets are moving, and occasionally there are also rhythmic whispers, like someone whispering in his ear, but no one can hear what they are saying.

Anne quietly poked a head out of Catherine's chest, sensing the resentment from the soul left in the air, and sometimes pointing in a certain direction. Catherine led the team to the direction Anne pointed, and was careful to watch over the surroundings while walking. She was always ready to fight the puppets that were unknown where they would come out. Vivian was busier than Catherine. Fortunately, she had been used to using magic tricks, otherwise her hands would not be enough. Vivian held the instant map of indulgence in delivery in both hands, and

Shi controlled the magic silk thread and let a piece of paper hang around the real-time map. Referring to the changes in the real-time map, he kept drawing the passing roads on the paper, expanding the scope of the map. The two maids, Pansy and Mimosa, looked at each other. The only lighting work of the two now was replaced by the fluorite belt above their heads. They were completely idle, so they consciously pulled out the dagger for self-defense from the base of their thighs. One left and one right protected Vivian on both sides, trying their best to follow the steps of the pros.

"Drip", a sudden short prompt sound shocked the four people who were rushing all their hearts, and followed a string of incomprehensible voices sounded from all directions. Catherine protected the three people behind her and quickly retreated to the edge of the pipeline, preparing to welcome possible changes. But the changes did not appear. After the voice, the entire surroundings returned to the original silence, without any abnormalities at all.

"Vivian." Catherine did not relax her vigilance, and her eyes were still scanning around her, asking without looking back: "It was the goblin's language just now? Do you understand?"

"I can't understand." Vivian smiled bitterly: "I can only understand some of the words, but it's really a bit embarrassing to let me listen to the pronunciation. Alas, only when I use it, I know how important it is to master the spoken language and listening of a foreign language. But I don't know at all that I can't understand, I can hear a few words."

"Can you guess the meaning?" Catherine asked, "It's fine."

"It should be a warning." Vivian hesitated and guessed: "It will be a change, and then something needs to be avoided. This sentence seems to be related to height, so I can only guess these things, which basically doesn't make much sense."

"No, it still makes sense." Catherine slowly put down the guardian in front of her: "It should not be a sign that the cleaning puppet is about to appear. This is good news. But the bad news is that this kind of change may be more difficult to deal with than cleaning puppets."

The four of them stopped in awkwardly and wanted to continue moving forward. They were worried that the changes mentioned in the voice would bring unpredictable dangers and wanted to stay in the same place. However, they were worried that the so-called changes had actually ended and they were still stupid and didn't know it, and they were in a dilemma for a while.

"I remembered a joke." Vivian said in pain: "More than 300 years ago, a gang of wizards had an academic exchange with the orcs' ancestor temple. One year, an orc shaman came to the Starry Sky Tower to study. Before leaving, the shaman made up for a period of common words and could read most of the magic documents normally, so he came with confidence. After arriving at the Starry Sky Tower, a disciple in the tower warmly received him, arranged a residence for him, explained in detail the habits and taboos in the Starry Sky Tower, and finally told him three magic words that passed the magic gateway when entering and leaving the Starry Sky Tower. However, people later discovered that this shaman had a very strange habit. Every time he entered and exited the Starry Sky Tower, he would do it.

The shaman passed by standing upside down, without an exception. Everyone was confused, but they thought this might be the custom of orcs, so they didn't ask. In this way, the shaman studied in the tower for two years and finally returned to the grassland. Before leaving, his friends couldn't help but be curious, so they asked this question, and the answer made them laugh and cry. It turned out that when the disciple who was the first to receive the shaman explained the access control magic words to him, he told him that when he said these three magic words, as long as the body was in the correct position, the order of the magic words could be reversed and would not affect the judgment of the access control, but the shaman's hearing was not good. He thought that he wanted to put his body in an upside down position to not affect the judgment of the access control, so he went in and out for two years."

"The joke is so good." The three of them looked at Vivian who was smirking with a dull face. Catherine hugged her arms and said, "Although I didn't find the joke, I felt a little stuffy just now. Now it's much cooler, it's all your credit."

Vivian put away her smile boredly and said unhappily: "Maybe I've understood it wrong, why don't we keep going?"

"Okay." Catherine nodded and said, "It hasn't changed for so long, so keep moving forward, just be more careful."

Before he finished speaking, a metal friction sounded from the inside of the wall. At about five or six meters above the wall above the heads of several people, a metal sharp blade, which was one meter wide and ten meters long, shot out from the inside of the wall, stretching forward, close to the edge of the canal and penetrated deep into the canal, almost touching the bottom of the canal. Not only did it last from the heads of several people, but in fact, three metal sharp blades poked out from the left and right sides and directly above to the bottom of the canal. This was the case until the end of the field of view. Looking closely, it was actually that

It is not a metal blade, but a metal plate, with a layer of fine and sharp serrated chains on the edge of the outer edge, and the sharp serrated teeth exudes a cold breath. After all the metal blades are in place, there is another "Didi" prompt sound. The chain with the serrated starts to rotate rapidly. At the same time, the metal plate begins to advance along the direction of the pipe, pushing forward until a distance of ten meters before stopping. After another "Didi" prompt sound, the metal chain saw re-entered the inside of the wall, and everything seems to have never happened.

"Maybe. Sometimes that orc shaman is right." Catherine said with a wry smile: "Vivian, your joke is still very philosophical."

"This chain saw... should be used to automatically clean up large-scale debris stuck in the waterway." Vivian said: "It's not a trap. It poses a great threat to ordinary people and low-level professions, but it's useless to high-level professions. Although it can destroy the golden-level *, it cannot break through the shield."

"Well. It cannot break through the Dou Qi or the magic shield." Catherine nodded and said, "But its cutting can consume a lot of Dou Qi or the magic power, which is also a problem."

Pansy swallowed heavily and whispered: "If we had walked in the canal just now, my sister and I would have died once."

"No." Catherine said: "This advancement is actually very slow. We have enough time to open the shield and block the front and then cut the chainsaw. However, it seems that we have to be a little careful about this kind of trap that is not a trap."

"So you two should try not to leave us too far for safety." Vivian emphasized again: "You must remember."

"Okay. I don't know how long it will take for the next cleaning." Catherine thrust her waist and stood up from the corner and said, "Take this opportunity to hurry up."

As soon as he stood up, Catherine suddenly found that the pupils of the two maids contracted. Her eyes were fixed on her chest, but after staring for a few seconds, she quickly moved away like she was escaping, pretending to see nothing. As soon as she lowered her head, she found Anne poking her head out of the pendant and looking at the two maids curiously.

"Oh." Catherine sighed distressedly, rubbed her forehead and said, "Did you see it?"

"No. We didn't see, we really didn't see anything." Pansy almost blurted out with the volume of shouting. The two maids were used to seeing people who suddenly disappeared because they knew too much. They knew very well. Many times, they knew that they only brought death. And she also knew very well that when faced with the two high-level professionals in front of her, she and her sister had no room for resistance, so when Catherine asked a question, Pansy shouted without thinking, but only then did she realize how ridiculous her answer was.

"Sister, it's useless." Mimosa smiled bitterly and reached out to hold her sister's hand: "Yes, we saw a girl in the dead. However, if you want to kill us, even if there is no effect, we will definitely resist."

"I wonder if you have the habit of talking casually?" Catherine asked with a calm expression.

"Huh, thank you." Pansy instantly understood Catherine's implication and breathed a sigh of relief: "We will never say it out, nor do we have the habit of talking to each other in our sleep. Thank you."

"Actually, my sister doesn't care at all." Vivian said as if nothing had happened: "Many people know about this. They just hide it from you just to avoid trouble. Don't worry, if you kill someone for such a small matter, is that the elder sister worthy of being a knight? Also, you will also leave the people of the Innocence City in the future. Try to try to look at the problem with a way of thinking outside the Innocence City. Not everyone will disappear because of a small matter."
