Due to the presence of air in this shelter, the five of them could communicate normally, and naturally there was no longer a need for the communication channel of the information bridge, but at this time, Cheng Shi and Barbara were suspended in mid-air a few hundred meters away, and at such a distance, even a big bird with sensitive ears could not hear what they were saying at all.

"What are your brother and sister-in-law talking about there?" Yang Yang asked, holding a crystalline stone-like thing in his hand, looking at North.

North shook his head: "Second sister can't overhear, how do I know." She rolled her eyes, "Where did you find this baby?" ”

Yang Yang suspended the thing in his hand in front of the little mermaid, and said proudly: "I don't know what it is, I found it in the hut just now, I took it away when I looked good, it may be a magic stone, I still have one in my pocket, if you like it, my sister will give this one to you." ”

North stretched out her hand to grab the crystalline in front of her, looking at its colorful appearance, she was also very curious, but in an instant, she showed a look of surprise: "Second sister, this is an ice cube." ”

Yang Yang was stunned: "How can it be an ice cube?" Saying that, she rolled her eyes, "Ice cubes are ice cubes, anyway, they won't melt here, so let's play with them first." ”

North let out a sigh and casually put the strange piece of ice in his pocket.

Yang Yang was very displeased to see that Cheng Shi and Barbara, who were suspended in the middle, did not come back for a long time, and waved at them and were ignored, so she leaned on the fence of the corridor and looked down, but in an instant she retracted her neck.

No. noticed this detail and asked curiously, "Second sister, are you still afraid of heights?" ”

Yang Yang was slightly embarrassed, and then waved his hand pretending to be indifferent: "How come?" Didn't we levitate in a pit when we were in Mizelle Faro before? That hole was much deeper than here. ”

North frowned: "I think my brother they may have found something, let's go look for them." ”

Yang Yang said "ah" lightly, and then nodded very reluctantly: "You can go if you say go, anyway, I want to ask them, just now I waved at them and ignored me." ”

"Let's go, then." North floated out of the hallway.

Yang Yang closed one eye and flew out with a shudder.

In fact, when they were at the entrance of Mizellefaro before, although the hole was bottomless, the further down it went, the darker it became, and the gas gushing out of the hole was extremely dense, so the hole did not intuitively feel very deep, the most important thing was that there were people coming and going, even if the air in the cave was not very good, it could give people an inexplicable sense of security.

But the shelter was full of horror, first the lights that had not been extinguished for thousands of years, then the bones of children in many rooms, and the air that did not contain any impurities, even though they were suspended more than two thousand meters above the ground, they could still see the floor below at a glance. And there are only a few of them alive in the entire shelter, and thinking about these strange situations is inevitably terrifying.

"What are you doing here?" Yang Yang looked resentful, "I don't even pay attention to me when I greet you." ”

Barbara glanced at Yang Yang: "Are the birdmen still afraid of heights?" ”

Obviously, the monkey girl could see at a glance that Yang Yang was a little scared here. The big bird straightened her chest, only to hear a loud sound, her arms instantly turned into a pair of wings, and then not to be outdone: "Hmph, who is afraid of being tall, will you grow wings?" ”

Barbara cut and shook her head in silence.

"Did you two find anything new in those rooms?" Cheng Shi's gaze wandered on Yang Yang and North.

"Second sister, she ......" North didn't say yet

After speaking, he was gagged by Yang Yang's floating over.

Seeing this, Cheng Shi understood what was going on after thinking for a while: "Did you steal things from the room again?" ”

Yang Yang spread his hands and pretended to be casual: "No, we can only take two pieces at most, we just looked around." ”

Cheng Shi naturally wouldn't rummage through the girl's pocket casually, so he knew that Yang Yang was lying, but he was helpless: "What about the big one?" I wonder why he stayed in the house for a long time and didn't come out? ”

Yang Yang pointed in the direction they had just come: "Just now I saw him studying some jars in a big room there. ”

Cheng Shi sighed, feeling that the two of them had been suspended in mid-air for a long time, so he thought about going to Oldman to talk about some of his speculations with Barbara just now, maybe he would have a different opinion.

So he waved his hand left and right, and the four of them flew in the direction of Yang Yang's finger just now.

After many space flights, several people became more and more proficient in operating life jackets, and the four of them almost didn't step on the brakes, twisted their bodies and came to the big house where Oldman was.

"Big one, what are you studying?" Cheng Shi saw that the ground in this room was full of large and small bottles, and asked curiously.

Oldman: "Landlord, don't you think it's weird that these bottles can honestly stay on the floor?" ”

As soon as the giant said this, Cheng Shi suddenly felt quite strange, the gravity here was very weak, but there was air in the room, and the four of them had just floated in flexibly, and there would always be some air currents surging, and these bottles on the ground, no matter how big or small, did not move at all.

Cheng Shi scratched his head: "Just say it directly, did you find anything wrong?" ”

Oldman's originally somewhat mysterious expression suddenly became a little embarrassed, and he pointed to a large bottle with the bottom facing the sky at the door of the room: "I found a strange circle pattern on the bottom of that bottle, look at those logos, these bottles should be the nodes of the circle, so I arranged this circle according to the circle map, I don't know if it's because the years are too long, the circle can't be activated for the time being." ”

Barbara is most flexible in a gravityless but airy environment, and she immediately flew to the door to retrieve the bottle with a magic circle on the bottom of the bottle, and brought it to Cheng Shi.

The four of them saw that this was a bottle with a roughly cone-like structure, with a gray-white body, and there was no obvious difference between the materials used to make this bottle and those bottles around it, but this appearance was definitely outstanding.

Cheng Shi even felt that this bottle was not designed for practicality or decoration, if it was used as a container, it could not hold anything at all, and it would take up space to store, but if it was a decorative bottle, its appearance design was too lacking in beauty. In contrast, it's more like it was deliberately designed like this to cover up what was recorded at the bottom of the bottle.

The circle drawn on the bottom of the bottle is also very simple, the middle of the whole picture is a regular triangle, and each vertex of the triangle is the center of three circles of the same size, and five bottles of different shapes are drawn on each circle at equal intervals. In addition, there is one of the most striking places, where two alien characters are written directly above the circle diagram: Hope.

"Since it's a magic circle, those bottles that are nodes of the magic circle should contain some spell-casting materials, and a few empty bottles are placed there, and it is unlikely that there will be any magic effect." Barbara analyzed.

Oldman nodded, and then said thoughtfully: "I thought so at first, but under normal circumstances, if a magician wants to cast a spell, he should not put the materials used for casting spells in a bottle, which violates the basic logic of spellcasting. Since there was nothing in the bottles, I studied the bottle books

Body, I found that although they were similar in color, they were not made of the same material, and I suspected that the bottles themselves might be magical materials, so I arranged the bottles according to the magic circle diagram. When I put the first bottle on the floor, I noticed that the floor here had some kind of magical binding on these bottles, and I thought that these bottles were made of magic materials, but when I placed them in the position marked on the circle map, there was no magic effect. So I was going to reposition the bottles that looked a little bit like them, and before I could finish them, you guys came in. ”

Cheng Shi listened to the giant's meticulous thinking of studying this ancient magic circle, and smiled with satisfaction: "Big one, let's adjust the position of the bottle together, you will command, and we will be responsible for moving the bottle." As he spoke, he glanced at Yang Yang and North beside him, "You two didn't take or replace the bottles in this room, did you?" ”

The two underage girls looked at Cheng Shi with a serious face, and immediately obediently took out all the bottles in their pockets to show the team leader.

"Brother, no, the bottles in this room are not pretty, and when we came in, we saw that Uncle Crewe was busy, so we went out." North said very sincerely, and Yang Yang on the side also nodded vigorously.

Barbara saw that the two of them were each holding seven or eight small bottles, and looked disdainful: "You really take a lot, don't you say that you only take two?" ”

Yang Yang turned his head when he saw that Cheng Shi didn't say anything, and hurriedly put the bottles in his hand back into his pockets: "Cut, the landlord didn't say anything, you can take care of it." ”

"Wait a minute, I see there's a little colorful stone in those bottles just now, what is that?" Barbara asked, pointing to Yang Yang's pocket.

"Sister-in-law, it's not a stone, it's an ice cube, and the second sister also gave me one." North explained.

Barbara glanced at North suspiciously, "What are you doing with the ice?" Won't it melt in the spaceship soon? ”

The little mermaid spread her hands, indicating that she was holding it for fun for the time being.

Oldman carefully studied the circle again, and then began to instruct everyone to adjust the position of the bottles.

After ten minutes of busy work, the circle still showed no signs of activation, so it could be said that there was no response.

Just when everyone was a little depressed, Cheng Shi took the bottle with the magic circle painted and studied it again, he suddenly found that there was a circle faintly drawn in the center of this picture, it may have been too long, the circular line and the ravine had been blocked by other substances, but after careful identification, he could still vaguely see that there was indeed a circle drawn before.

"Big one, adjust these bottles to the position you originally placed, that should be the most consistent with the position of the bottles marked on the magic circle map." Cheng Shi said cautiously.

Everyone was puzzled, although they all knew that after restoring the position of the bottles, they would not activate the magic circle, but they didn't ask much, because it was not too difficult to adjust the position of a few bottles, and they wanted to see what new ideas the team leader would have next.

After a minute, under Oldman's guidance, the bottle's position was restored.

The five of them stood in a circle around the magic circle, Cheng Shi was still holding the strange bottle with the magic circle drawing in his hand, and the other four people were all looking at him curiously.

Seeing Cheng Shi jump up, he put the bottle in his hand on the center of the circle, and then quickly returned to the position he had just stood in.

Ten seconds later, three circular white circles of light gradually appeared out of thin air above the bottles at the three corners of the circle, and then the center points of the three circular circles quickly connected with each other, forming a regular triangle.

The five of them were stunned by the scene in front of them, a magic circle more than 5,000 years ago was activated like this.
