The carriage moved slowly, and after an unknown amount of time, the puppet stopped.

In the carriage, a flash of spiritual light instantly woke up the two people inside, Liu Bai sat up instantly, the carriage was closed all around, so he couldn't know the situation outside.

Liu Yiyi on the side woke up, she got up slowly, stretched her waist, and didn't forget to yawn, she slid lightly towards the side of the carriage, and a window appeared on the closed carriage.

It was evident through the window that they were no longer in the sand, and the two jumped out of the carriage to find that it was a complex of stone and brick buildings, but they were in a dilapidated state, and almost none of the houses were intact.

"Judging by the size of this village, it is estimated that there are only about 100 households, but the battle situation here is a bit tragic, there are stone residues everywhere, and it seems that some broken wreckage is buried in the earth. Liu Bai walked in the ruined village, and from time to time he broke open the clods of soil and saw the dry bones inside.

"It's been a long time since this place, but it's still underground, and it's strange what kind of force can bury such a large place deep underground. Liu Yiyi followed behind Liu Bai and looked at the buildings here, which were completely different from the Great Moon Kingdom on the ground.

"I think that even the power to move mountains and seas may not be able to do it, this should be a country directly sunk into the depths of the earth, but how are we going to get out? Is it directly chiseled against the stone wall on the ground? But this top is really high, estimated to be dozens of feet high. Liu Bai's first thought was to chisel it out directly, which was indeed the most convenient thing.

"I'm afraid this doesn't make sense, I just tried it, the top seems to be wrapped in a layer of formation, this layer of formation seems to wrap the entire underground world, and the only way we know now is the crack in the hall, which must have been opened by a powerful person, and he escaped through that gap. ”

"Do we still want to go back to the main hall?" Hearing Liu Yiyi's answer, Liu Bai asked rhetorically.

"No, since it is wrapped in a formation, there must be a way out, as long as I find the formation eye, I can guess the way out. Liu Yiyi said as she walked, unconsciously calculating something in her hands.

"It's looking for an eye again, then I can't help you, I really don't know anything about this. Liu Bai spread his hands and took the lead in speaking.

"Speaking of Senior Liu, what will you do? I always feel that you really don't know anything except a little cultivation. Liu Yiyi looked at Liu Bai angrily, and said with a blank look.

"You just call me Liu Bai, in fact, my situation is a little special, and it's not easy to tell you. After Liu Bai hesitated for a moment, he said, after getting along for so long, although she has not really determined who she is, she finally gets along very well, and Liu Bai is not so defensive of her in his heart.

"Liu Bai, it's really an ordinary name, I also know that you are special, I think I know the person who returns to the void, which is not a knowledgeable and versatile existence, it is really an accident except for you. Liu Yiyi pinched her fingers, looked at Liu Bai and squinted her eyes and said.

"I said you don't have to be sarcastic about me like that, I don't want to be so ignorant, I really can't help it. Liu Bai sighed helplessly and had to say.

"Okay, let's not talk about that for now, let me calculate the position of the formation eye first. Liu Yiyi silently remembered something in the palm of her hand, and from time to time popped a stone onto the big array, every time the stone came into contact with the big array, there would be a trace of extremely subtle ripples, and it was by relying on this ripple that she could guess where the array was.

As her hands moved faster and faster, so did she flick the stones, and it wasn't until a quarter of an hour later that she stopped.

Liu Yiyi looked at her hands in horror, with a look of disbelief in her eyes, "How can it be so big, how can this underground world be so big." ”

"How's the calculation, is this underground world very big?" Liu Bai looked at Liu Yiyi suspiciously, not understanding what the situation was in her mouth.

"This world is unbelievably big, I always thought that this underground country is at most the same as the Great Moon Kingdom, but just now I have made some calculations, I am afraid that this underground country is the size of the entire Seven Kingdoms of Middle-earth, such a large area of the country, has there been any changes in the past? Could it be that this was the orthodox world before, and now Middle-earth has been transformed? Why haven't I seen it in any classics? There should still be books in this world, so I want to find and study it. Liu Yiyi looked ahead, her eyes flashing.

"This is really a scholar-level character, and now at this time she is still thinking about studying the underground world, well, don't say it, in fact, I'm quite interested. Liu Bai looked at the ruined scene around him, and he really had a desire to explore, but he still knew in his heart that he still had problems that had not been solved.

"Anyway, shouldn't we find a way out first and think about other issues?" Liu Bai quietly came to Liu Yiyi's side and said in a low voice.

"Indeed, some people think too much, don't blame the seniors. She tried her best to calm the turmoil in her heart and return to a trace of normalcy.

"Although this underground world is very large, as far as I can see, this large array should have seven array eyes, corresponding to the number of seven buckets, and there is a formation eye about ten thousand miles away from us, I don't know if we can find anything useful. Liu Yiyi calculated again, pointed ahead and said.

"Then what are you waiting for, hurry up, get you out of a flying machine, and we'll hurry up. As soon as Liu Bai heard that there were still thousands of miles away, he thought of the empty shuttle that Liu Yiyi used before.

"Don't worry, senior, let me collect some things first. Liu Yiyi smiled slightly, and walked towards the dilapidated building, and after turning over some stones, he found a broken porcelain bowl, which was only half of the porcelain bowl still intact, and the porcelain bowl was printed with strange patterns.

This air shuttle is worthy of being a flying treasure, the speed is much faster than Liu Bai's driving clouds, along the way the underground scene is quickly passed, there are all kinds of high mountains connected to the top, there are dilapidated mountain villages, towns, and even a huge lake, and there is obviously a splash of water in the lake.

"I don't know if there are still living people in this underground world?" Looking at the ruins underground, full of ruined land and buildings, Liu Bai couldn't help but sigh.

"It's hard to say, but it's dark, there's no sunlight, and the vegetation is extremely scarce, so I'm afraid it's hard to survive here for a long time. Liu Yiyi shook her head, she couldn't imagine how desperate it would be to live here all the time.
