"This is a map of the 20 kilometers of sewer, including the part of the area controlled by the Shadow Hand, circled it in the map with a heavier color." After lunch, indulging and enthusiastic came to the door. Seeing Catherine's calm expression, the two sighed, knowing that Catherine and Vivian had not changed their minds, so they could only take out a map and handed it over: "Although the confidentiality level of these maps is not very high, it is also more important for Shadow Hand, so..."

"I will hand it to you after the end, including the part we have discovered. If there is any, I will hand it to you, and no copies will be left behind." Catherine promised.

"And this." Indulging in a look that was more serious than handing over the map, he handed a book-sized box: "Take this with you, don't lose it or ruin it. In the entire Yara world, only two of these things have been published, one of them is unknown, and the only one left is in your hands."

Open the box, and there is a screen made of crystals. The screen is pitch black without any pattern. Facing the questioning eyes of Catherine and Vivian, he whispered indulge: "This is an instant map. After activation, it can center the holder and display the terrain and pathways around the area of ​​fifty meters. As long as you can use this map board all the time, you can basically eliminate the possibility of getting lost."

"This kind of thing... I've never heard of it." Vivian gently pressed the map disk on his face and closed his eyes and said, "I can't understand the principle. Is it really that magical?"

"Yes, this is one of the highest technology in the last few decades of the Goblin Empire." said indulgently and seriously: "A rare finished product in a goblin ruin excavated in our guild. According to the research report that matches this item, there was only time to make two samples at that time, and it was not put into production on a large scale. Now no one knows how this kind of thing works, so it is very valuable. We have taken a lot of responsibility to lend it privately, so we must use it with caution."

"Thank you." In fact, even if you don't lend such items, Catherine and Vivian will search for it with all your heart. Obviously, indulging and enthusiastic lending this thing is not only for the smooth progress of the mission, but more for the safety of Catherine and Vivian. Catherine also saw this clearly and thanked him with some emotion: "I believe that I will not make you regret it."

"Also, bring your two maids." Indulge in looking at the side door of the room. He raised his voice and said, "They will bring you unexpected surprises."

"They are not combatants, aren't they?" Catherine asked in confusion: "I originally wanted to borrow the characteristics they are familiar with the dark alley area and ask them to help, but since they are going to the sewer, they are not familiar with it, so there is no need to let them face the danger below."

"You underestimate the residents of the Innocence City too much. I went back to investigate their information at noon yesterday. It was such a surprise." Indulge and shouted: "Don't you two come out to let the employer understand your abilities?"

"We are naturally sensitive to road search." Wearing a mixed black and white maid outfit, Pansy and Mimosa walked out of the maid's room and pressed on the hem of the skirt and whispered: "We can remember that no matter how complicated the terrain and road are, we have never been lost."

"I understand." said the indulgence: "They just appeared to assist you in this operation."

"But there is a very likely battle along the way." Catherine shook her head and refused, "As an ordinary person, not even a professional, it is still too dangerous to explore a place that has not been inhabited for thousands of years. No one knows what will happen inside."

"Ordinary people? Yes, they are indeed ordinary people." The indulgent smile was very cold: "But don't forget that this is the City of Innocence. The ordinary people in your eyes may not have fewer lives than yours, and they are no exception."

"Let's go with it, Miss Catherine." Pansy seemed a little reluctant, but she still took the initiative to persuade Catherine: "Although we do not have the combat power of professionals, we still have some confidence in the concealment and hidden aspects of breath. I think we can ensure our safety below. If we can help you, it can be regarded as repaying your care for the past two days."

"Okay." Catherine was silent for a while and nodded and agreed, "But when we can't take care of it, you should give your own safety first."

"Sister!" Vivian was surprised that Catherine actually agreed. She said anxiously: "Sister, if you do this, you really..."

Catherine stopped Vivian's words with her eyes, shook her head gently before asking about indulgence and enthusiasm: "Are the items ready?"

"The items listed on your list are all ready." Wan Xiang said: "Hidden near the entrance of the sewer in advance, just take them out before going down. I don't know how long it will take for you to go down this time, so we really can't go with you. If there is any problem, you can solve it yourself. Okay, hurry up and set off, and give you a detailed introduction to the specific situation of the sewer on the way."

"I have one last question." Catherine frowned tightly and asked worriedly: "It may take several days or even ten days to go on this time. What should I do if I rent and car fare? Otherwise, you can convert these two fees into cash to me in the number of days?"

He turned his head and left, and he was too lazy to say a word. Vivian also secretly covered his face, pretending not to know Catherine, and stumbled out the door, leaving only the angry Catherine chasing behind and shouting: "Hey, I'm serious, listen to me."

The sewer system is one of the representative works of advanced technology during the Goblin Empire period. The huge underground waterway with a coverage area of ​​nearly 1,000 kilometers connects seven or eight nearby cities, solving the urban drainage problem for millions of people. The sewer is composed of huge hollow cylindrical structures with an inner layer of 30 meters in diameter. As the only part, it is made of a layer of goblin special metal as the core, and the inner and outer surfaces are cast with glue solids with steel bars as the skeleton. After solidification, these gelatinous bodies have no less hardness than rocks. They are hard and have a slight elasticity, which can better resist the pressure applied by the bottom layer.

Because the space inside the sewer is too vast, a large number of monsters live in it. Most of these monsters are small monsters such as rat monsters and soft monsters. Occasionally, some medium-sized monsters that can't get out of the sewer are also reproduced, and the number of monsters will increase. It needs to be cleaned regularly on a large scale. However, goblins are unwilling to consume a large amount of manpower in the cleaning work of sewer internal cleaning, so they created a large number of mechanical puppets for cleaning. Although they are called cleaning, they actually exist to hunt and clean the monsters and have a certain degree of combat power. Due to the age of goblins, many intelligent creatures on the continent were not coexisting as they are now. Therefore, the instructions they received were to clean up all non-goblin creatures that were not certified within the detection range, so whether it is a monster or a human, they would be attacked indiscriminately when entering their detection range.

The sewer preserved underground in the City of Innocence is 840 meters away from the ground. Of course, it was not that the goblins built this system so deeply, but that it had been nearly ten thousand years. The soil layer was naturally thickened. This sewer has four known entrances and exits, two of which are located in the current headquarters and former headquarters of the Thieves Guild, namely the Guild and the Dark Alley Area of ​​the City of Innocence. The other two small exits, one is near the Bayergas River, and the other passes through the Bayergas River from the underground, located in the cave inside the Pandora Mountains at the end of the sewer.

For a hundred years, the Thieves Guild has managed the sewer area it controls like an iron barrel. There is no loophole to invade. Among the three demigod presidents, there will always be one of them in the guild for many years. Any sudden critical situation can be easily solved. The simplicity of indulgence and enthusiasm for Catherine is to not contact Shadow Hand, and never get close to Shadow Hand's territory. Due to the unique sensitivity of Thieves and Assassins, the defenders outside Shadow Hand base often use the kill first and then ask questions for creatures close to the base, so even if Katherine and Vivian hold the Shadow Hand invitation token, there is a high possibility of unnecessary conflict.

"That's basically the situation." Indulgent summary: "You can understand other situations by looking at them, so I won't say much."

"But I have a question." Catherine and Vivian were sorting out supplies provided by enthusiasm and indulgence outside a building. Hearing the words, "Even if there are too many goblins cleaning puppets, they can only consume and not replenish. Hundreds of years are enough to clean up the puppets inside the sewer fragments of 200 kilometers. Why do you think so many?"

"Who said there is only consumption but no supplement?" Endless smiled bitterly: "I don't know why. Even if a puppet is completely destroyed and all its parts are destroyed, a new puppet will appear from the original puppet entrance and exit a few days later. Some people once guessed that there was a puppet replenishment system outside the outer wall of the sewer, but if you want to verify it, you have to completely destroy the sewer. So you can only maintain the current situation. Don't look at the current control range of only more than ten square kilometers, but for these more than ten square kilometers, the two demigod presidents at that time were personally in charge of another demigod wizard. The three of them worked together for twenty years to create several small-scale directional earthquakes at the seven puppet entrances and exits within this area, and completely blocked the entrance and exit, which is why the current situation is here. If you want to expand outward, it is not as easy as you imagine."

"Okay, all the supplies have been checked, no problem." Catherine and Vivian carried the usual adventures back on their backs with a backpack, and finally sorted out their equipment: "We're going to set out now."

"Good luck to you." He stared at the two girls with indulgence and enthusiasm: "We are waiting for your good news outside."
