The carriage slowly moved forward on the sand, and a puppet in front of the carriage walked with stiff steps towards the main hall not far away.

This hall is extremely strange, there are no other buildings in the annex, even the grass and trees do not exist, and there is nothing else out of the yellow sand in the sky.

Time is like flowing water, I don't know how long it has passed, the puppet was blocked by the bluestone wall of the main hall and stopped, and the carriage behind it also gradually stopped after losing power, and a white light flashed in the carriage, so that the two people who sealed the six senses woke up.

Liu Bai opened his eyes, his body unconsciously sat up, he also learned Liu Yiyi's previous movements, and gently wiped on the wall of the carriage, and a window appeared in front of him, although there was still a sand all around, he could already see that the bluestone wall of the main hall was close at hand.

"It seems that we have arrived in front of the main hall, but I didn't expect to go around and around and return here. ”

Liu Bai walked out of the carriage and stood in front of the door of the main hall, looking at this heavy iron door, he was really full of emotion, although the stone gate inside made him instinctively not want to approach, but now there is no other way, if he wants to get out, he can only escape through the cracks in the wall, and as far as the current situation is concerned, this hall does not show danger.

Liu Yiyi had already come behind Liu Bai, but she didn't feel as much emotion as Liu Bai, she looked at the hall with a bit of solemnity on her face, as if the hall had changed differently.

Liu Bai put his hands on the iron door and pushed it gently, but found that the iron door did not move at all.

"Huh! ”

Liu Bai increased his strength a little, and a trembling sound emanated from the iron door, but there was still no response, as the strength continued to increase, Liu Bai's face began to turn red, but the iron door was still not pushed open.

"How can this be, although I am not known for my strength, but the strength just now is more than enough to lift a small mountain, but how can I not push this iron gate?"

Liu Bai let go of his hands, looked at the iron gate with some doubts, clenched his fists, and a Buddha Yuan condensed, and he punched towards the iron gate.

Only a loud "bang" was heard.

Liu Bai's fist slammed into the iron gate violently, but the iron gate was not smashed out of a hole by Liu Bai's punch, but shook his fist open, and Liu Bai shook off his somewhat painful hand.

"Xiaobai, don't try again, this door is not made of ordinary iron, I haven't seen it before, this should be made of Jingyuan cast iron. ”

Liu Yiyi grabbed Liu Bai and told him not to try, she stepped forward and stroked the surface of the iron door, the place where she had just collided with Liu Bai was still smooth as new, and there was not even a trace of unevenness.

"What the hell is Xiaobai? Why do you call me Xiaobai, you embarrass me like this. Liu Bai didn't listen to Liu Yiyi's words at all, but was full of the title Xiaobai.

Liu Bai was depressed for more than ten years because of this nickname before he crossed over, and now he has crossed over, although he has become a real person who has returned to the void, he didn't expect this unforgettable nickname to appear in the end.

"Xiaobai, don't be so stingy, do you call you Xiao Liu? How strange that is, we have lived and died together, right? ”

Liu Yiyi turned her head and winked at Liu Bai, and said in a pleasant voice.

"Well, well, that seems to make sense. Hearing this pleasant voice, Liu Bai also felt soft in his heart, and couldn't help scratching the back of his head and saying.

"Poof" Liu Yiyi couldn't help but cover her mouth and smile when she saw Liu Bai like this, as if she was amused by his appearance.

"Okay, I'm not going to talk to you about this, how do you open this damn iron door?"

"This kind of fine cast iron is a very special metal, which seems to be almost the same as ordinary mortal iron, but regardless of the density, hardness, and toughness are terrible, and it must not be opened with a strong one. Liu Yiyi stroked the position of Liu Bai's blow and told him about the particularity of this metal.

Liu Yiyi crossed the iron gate, came to the bluestone wall next to him, and tapped lightly with his hand a few times, "And although this hall is made of bluestone walls, there are faint spiritual patterns engraved on it, spiritual patterns are legendary things, at least they have not appeared in our world, I have mentioned them in an ancient book, the spiritual patterns seem to have been developed by a great power, and this kind of wall carved with spiritual patterns is even a little harder than the iron door of Jingyuan cast iron." ”

Listening to Liu Yiyi's introduction, Liu Bai instantly gained a lot of knowledge, although it was useless, but Liu Bai still listened to it with relish, but a sentence suddenly popped up in his mind, "Anyway, you explained so much, but how do we get in, I remember that we obviously didn't close the door at that time, it's really strange, could it be that the stone gate inside closed the iron door?"

"Why do you say it so tongue-twisting, the stone gate closes the iron door? Liu Bai said what he had just thought of, but suddenly found that something was wrong in his heart, and couldn't help but complain secretly.

Liu Bai said this, Liu Yiyi was also slightly stunned, at this moment, there was a strange sound from inside the iron door, only the sound of two knocks and things falling, and then the iron door was slowly opened in the creaking sound.

Liu Yiyi came to Liu Bai's side in a flash, pulled him down to the wall next to the main hall, a small white bead appeared in his hand, and threw it towards the ground, the white bead turned into a smoke to envelop the two, and then the smoke dissipated, and Liu Bai and the two had already dissipated in the smoke, in fact, the two did not dissipate, but a barrier appeared in front of the two, hiding their figures and breath.

The iron door was slowly pushed open, and two people walked out, a man and a woman, the man was tall, handsome, wearing a green robe, and the woman had a white face, a pair of extremely beautiful eyes, her eyes were as clear as the sky, a long hair was coiled on her head, and a few jade hairpins were pinned to her head. The tall figure and a light blue dress look particularly beautiful.

"Is this something to do with the stone gate?" the man walked out into the sand, surveyed the bones on the ground, picked up a broken blade, and flicked it, breaking into knots like dead wood.

"It seems that these weapons have gone through too long and have become decayed, and the golden essence qi in them has basically been lost. ”

"That's true, this should be an ancient battlefield, are they fighting for this stone gate? But since someone blocked the stone gate here, they should just not want people to get it, it seems that there should be something hidden here, but unfortunately there are many historical truths that have been lost in the long river of time, which will lead to many things that are puzzling. The woman walked helplessly forward, looking at the wreckage around her, which were all relics of history.

Inside the barrier, Liu Bai looked at the pair of men and women in horror, he stretched out his hand to point at them, but there was no word for a while, his heart was in chaos at the moment, and he couldn't believe what he saw in front of him.
