The body of the requiem bell is indeed not big, only half a meter in diameter, and the bell body is engraved with all kinds of strange groups, and the surface is covered with blue-green patina, which looks quite ancient. Reaching out and caressing it gently, it was cold and rough in my hand, full of the heaviness of metal.

Knock it lightly, and the sound doesn't seem to be anything special, and the force is slightly increased...... So Babu was chased away by Monica.

Monica finally stopped checking the bell and reluctantly stuffed the requiem bell into her purse.

"One hundred and twenty hours to resume the use of one time, a total of three times, during the sixty seconds after the ringing, all non-higher intelligent beings within one kilometer will lose their hostility, and return to normal after sixty seconds. The target of the loss of hostility is to equip the place to which it belongs conceptually, and the effect of hanging on the car is the entire caravan, including the people on it. Reaching into the handbag and touching it a few more times, Monica pulled the handbag with satisfaction, "The effect is actually not very strong, but this kind of tactical-level edge equipment is rare, and it is the first time I have seen it with my own eyes." And it's so useful for us, a total of 180 seconds, enough for us to escape most dangers with the caravan. It's just such a requiem bell, which is worth several times more than all of our net worth, no, I can't bear to sell it for any amount of money. ”

"However, the price we paid is also very large." "Not only are all the food available, but even Anna's two pigs are gone, so angry that she gnaws at me to vent her anger, but we must help them deal with the source of the disaster." It's their own business, and they still want us to help finish it, huh? Why are you staring at me like that? ”

"It's nothing, I'm just curious how you managed to say such things without blushing at all." Monica poked Babu's arm, "Actually, I'm still blushing, otherwise I wouldn't have offered to join forces with them to solve the problem." ”

"Who knows if it's red or not, I forgot to bring that thing out when I left Thortown." Babu coughed a few times, picked up Anna and opened the door, "Let's go, let's go and help them open that door first, more than a thousand people have been blocked by one door for so long." ”

Although only a few hours had passed, the atmosphere in the auditorium had noticeably changed.

The entire first and second floors of the auditorium were filled with the aroma of bread and dough, and the long-lost smell of stewed meat reminded people of normal life before the disaster, and they couldn't help but burst into tears, and from time to time a little head came out from under the basement stairs, secretly looking at when the meal would start, and in the little head, Nina was the one who hit the head, but as soon as she saw Babu seeing her, she immediately went back to the basement and didn't come out.

When I came out for the first time a few hours ago, many people who couldn't help but stay in the corner still looked blank with empty eyes, but now many people even have smiles on their faces, and their movements are much faster. Even the wounded in the hall were much quieter in pain, and the wounded were holding a string of beaded fruits in their hands, and the others who were hungry were eager to go out and get some injuries immediately.

"You're down?"

Linda, who was distributing beaded fruits to the wounded one by one, looked up and saw the three travelers coming over, she held the hand of the last wounded and said a few words, and then walked up to the three and saluted lightly. Not long after they separated, the tiredness and weakness she had just now had disappeared, and she had regained the seriousness of the strong woman who carried the fate of all the survivors on her thin shoulders.

"Don't worry, we are honest businessmen, and since we have received the advance payment, we will complete the transaction, and we will not run away secretly."

Linda didn't pay attention to Monica's teasing, but smiled to the side, and her brother-in-law, Algan, was retreating from the courtyard to the auditorium with a few sturdy young men. Some of the other people who had already been prepared in the auditorium joined them, and there were more than twenty men and women, all of whom were strong and strong, and each of them had various tools in his hand.

"The battlefield in front has been arranged, there will be no problems in a short time, and someone will come down to inform us if there is a problem."

Algan changed into a two-handed sword, his momentum was calm, and his complexion was much better than when he was injured before. Babu and Monica glanced at the locations where he was injured, saw that he was moving freely, and knew that the therapist had taken care of it, before nodding.

"Don't worry, Mr. Merchant, Miss Merchant, none of us in Tanuki Town are cowards, you have helped us a lot, and even pointed out the location of the enemy for us, no matter what the result is, we will never forget your kindness, thank you."

"Uh-huh." The two nodded vigorously, but the smile on their faces was inevitably a little embarrassed, and while the others were not paying attention, the two met their eyes, and Monica stuck out her tongue mischievously at Babu like a little girl, exchanging tacit glances.

Linda and Argan led the way, followed by the travelers, followed by more than twenty strong laborers with tools, and a group of people marched into the underground shelter, followed by curious idlers from time to time, making the team grow stronger and stronger.

"By the way, Mr. Merchant, this is the structural diagram you wanted, only the structural diagram of the entire underground shelter. Oh, that's good, but," Linda reconfirmed, still a little uneasy, "I remember the former mayor told me that if this door was to be forcibly opened, it would not be possible to do it in seven or eight days. Can it really be as easy as you say, just a few hours? ”

"I don't know how to break the ...... Those who open the door can only forcibly destroy it, and of course it will take a lot of time, but it will be easy to master the method. Babu didn't rush to open the door, but looked at the iron door from a distance and said, "I'm more worried about what to do after opening the door than whether I can open it." ”

"Huh?"

"You ...... We have been able to hold on until now because there is a danger to defend, as long as we hold the wall, those crazy people will not be able to enter for the time being. But what if you lose your location? Babu pointed to the iron door, "If those madmen come out of it and attack us on both sides, it will be like we will send ourselves to a dead end." ”

"Oh, don't worry." Halfway through that, Linda and Algam relaxed, and Linda explained, "Those weird ...... The townsfolk who sealed off didn't come out of nowhere, and neither were the monsters that livestock had transformed, they were all alive in the first place. And there are no creatures in the deep caves except for small things such as bugs and mice, so there is no need to worry about something coming out of thin air. As for bugs and mice, there has never been a precedent for mutation in the past few days, and it should be because they are too small. So we can be sure that there will be no enemies inside, except for ...... What we're looking for. Mr. Merchant, Miss Merchant, you have not said, what is that thing? This door hasn't been opened in months, how did it get in? And, what exactly is its purpose? ”

"We can't give an answer to what it is." "It's just pure speculation, maybe some kind of alien that only exists in the illusory world, and wants to invade the present world in all kinds of strange ways. Well, we've actually encountered similar things before, so we're so sure it's this kind of thing. I really don't know how to get in, and as for its purpose, who knows, it's not really for the sake of food......"

In the middle of speaking, Babu suddenly stopped, motionless as if in a daze, and the people around him waited for a long time without seeing his reaction, until Monica poked him in the waist, and he woke up like a dream and wiped the cold sweat from his forehead.

"I'm sorry, I suddenly remembered something else, I was distracted, let's deal with this door first." Babu smiled, refocused his attention, listened carefully, and made sure that there was no sound or any special energy response, before gently tapping on the iron door and saying, "Actually, I don't like this kind of door very much, because it is too easy to open and not challenging. ”

A group of people around, especially Linda and Algon, had subtle expressions, only Monica, who looked at Babu's back with some confusion, with her understanding of Babu during this time, she felt that Babu was likely to think of something very strange and was taken aback.

"This kind of door is not locked with a door lock, it is locked by internal machinery, and the opening and closing are mechanically driven and controlled. It does look safe, but there is a fatal weakness in it. ”

While talking, a group of people were already gathered at the door, and there were many idlers watching the excitement in the distance, making the originally spacious door seem quite crowded.

Babu didn't care much, and opened the underground structure map provided by Linda to take a closer look, and the look of the monograph made the noisy onlookers gradually and consciously stop whispering. Seeing that Babu was distracted, Monica held up a lantern beside him to let him see more clearly, and met Babu's grateful eyes, Monica responded with a faint smile, put her hand on Babu's shoulder, and pressed it gently.

"Heh, I'll talk to you later." Babu patted Monica's hand, then closed the drawing and never looked at it again, paced back and forth in front of the iron gate with his hands behind his back, walked a few steps, stuck it on the rock wall and listened, and did not forget to explain, "This kind of mechanical door, no matter how exquisitely made and how ingenious the design is, the necessary components will not change, and the control part, the power part, and the transformation part are all indispensable." In addition, this mechanism has an unchangeable feature that all its signals rely on physical conduction, that is, each part is connected by parts. ”

"The more complex the system, the more and more complex the parts are used to conduct between the parts, and these parts need to occupy space." Babu banged on the wall and said, "In other words, the inside of the wall around the iron gate is actually partially hollow, and there are various parts scattered inside, and the stone wall outside is actually a back-up stone. And if we find where these parts are, we're already halfway there. ”

With each word, the Báb drew a small circle on the wall with his pen, and by the end of the sentence, there were nine more marked places on the wall.

"Come on, that's it." With the final stroke, Babu kicked the wall with his hands behind his back and said to the group of strong laborers, "Chisel out all the circles of the painting, and there should be at least three parts in at least three of the nine places." By the way, when chiseling, the action is lighter, in case the contents are broken, then you are responsible for yourself. ”

By the time a group of young strong laborers rushed up, Babu had retreated to Monica's side, and seeing that the attention of the others was focused on the construction site, he explained in a low voice, "Don't worry, I'm fine, but I suddenly remembered what those aliens were trying to do in the present world." ”

"Huh?"

"When I saw it just now, it seemed to be holding on to a bubble-like point of light or a ball of light, if you abstract it a little bit, the only thing it is holding on to now seems to be this present world, and that point of light will represent this present world. Then he asked Anna what that thing was. ”

"What about her answer?"

"Delicious."

"Ha, that's her style." Monica's smile suddenly froze, and then disappeared little by little, she took a few deep breaths to calm her mood, and then controlled her voice and whispered, "Delicious?" It...... Eat...... People of this world? Or do you eat the present world directly? ”

Before Babu could reply, there were several sounds of stone shattering from the construction site, followed by a cry of surprise.

"Chisel through."
