Okay, Gu Ling should start preaching and instructing herself on how to understand Jin Wen, but this time she will definitely not ask her stupidly, do you know Jin Wen?

Gu Ling began. The left arm points to the left wall, this is the "Corpse Refining Curse Seal", yes, yes. She pointed to the right wall again, this was the "Hundred Gu Refining Formula". Immediately afterward, she pointed straight ahead, which was the "Natal Chart." ”

Wait, Zhu Beichen collected his memories and suddenly realized that Gu Ling's order was wrong!

The content of the inscription on the right wall and the gold inscription in front of him is opposite, he can't read the gold text, so naturally there is no way to confirm whether the gold text on the stone wall has changed, or Gu Ling deliberately pointed to the wrong direction.

"The one in the rear is the arithmetic medical prescription." It was the last time he heard Gu Ling's voice. Zhu Beici's scalp was numb in surprise.

He was sure that he had heard it correctly, that it was an ancient prescription that he had been looking for, and that it was written in golden script. It's in the wall of the back door, the giant bronze door.

Sure enough, a wall appeared on the bronze giant door that disappeared behind, and the walls were also densely packed with golden characters.

Hey, there's a hollow front and back! Now there is indeed a wall there, a wall full of golden texts, but it dilutes the joy in Zhu Beichen's heart.

He still couldn't help but touch the wall, and he had forgotten the most important thing. Before coming down, he kept hinting to himself many times that he must keep an eye on Gu Ling, the old woman, and never let her disappear again inexplicably.

But he still ignored Gu Ling's existence at this time, and his entire body and mind were concentrated on the stone wall behind him engraved with the arithmetic medical prescription.

"Beichen-Beichen, I, my grandmother seems to be missing!" The three thousand in the back looked solemn, and they were reminded many times before Zhu Beichen came back to his senses.

What the! Zhu Beichen's face changed drastically, and he hurriedly turned around, in the center of the nine-pointed star array, where was there still a trace of Gu Ling.

"I-I,..." Michijo just wanted to say something.

"You don't have to explain, I trust you." It's like remaking a TV script, but the editor has made some changes, thinking that he will stare at Gu Ling wholeheartedly, but he still ignored her distractedly. This is definitely caused by the wall in the back, which is not inserted according to the script.

Whew, Zhu Beichen exhaled a cool breath, he understood what he needed to do next. The walls on all four sides had been sealed, and only the nine-pointed star array in the center of the stone room floor was dazzling, occupying the sight of the two of them.

He took out the jade plaque again, held it in his hand, and stood in the center of the nine-pointed star array.

"When did you learn to control the Gu technique?"

Zhu Beichen said secretly, Lao Tzu himself doesn't know how I learned it, and I really don't want to talk to you anymore, you look like a wooden man, and I don't know if it's my own dream. If you can't get out, will you die directly in your subconscious, in your dreams?

He closed his eyes and meditated. All he needed to do now was contact the worm in the jade plaque.

The innocent head of the little insect appeared in front of Zhu Beichen after a while, the familiar taste, the familiar baby crying, just,

……

It looked at Zhu Beichen in horror, what was it afraid of, it was hard to imagine that it would show a frightened expression on its translucent head. It just swayed violently in midair, trying to resist a force, and it was expressing its fear with action.

It is not looking at Zhu Beichen, and what it is afraid of will naturally not be Zhu Beichen. Looking for the eyes the size of the insect's black spots, it looked at the wall behind Zhu Beichen, the wall after the disappearance of the bronze giant door, engraved with a prescription for studying medicine!

It's cracked, the halo is cracked! The insect in front of him was like a shattered screen, and its body was scattered in the stone room bit by bit, without the wail and cry before death, and it did not make any sound.

Zhu Beichen still had his eyes closed, and he suddenly felt cool and shady behind him, as if something was dragging his body with difficulty and causing the ground to move, and suddenly felt that someone was blowing at him around his neck.

However, there could only be one person behind him.

The light in the stone chamber had dimmed, and the light sources on the four walls seemed to have been turned off by someone, and the nine-pointed star array stopped running at the same time.

The thin eyelids of human beings can more or less perceive the light of the outside world in strong light, even in low light, but the stone chamber instantly fell into darkness.

Oops!

Dream and reality are actually like two sides of a mirror, and all images in front of the mirror are opposite in the mirror. Standing at different angles, the light refracts different angles, and the images obtained are completely different. However, no matter how the angle shifts and changes, the main outline of the image is the same in the mirror, but what may change is that in the process of changing the perspective, some angles of the image are obscured. This can be a good explanation, why behind the first bronze door, the living corpses that should have existed are gone, in fact, they have always been there, but they are standing from the wrong angle, and they are not found. And this stone room is the same, for the first time, because of the problem of perspective, I couldn't find that after the bronze door disappeared, there was a gold text on the wall. And Gu Ling couldn't disappear out of thin air, but he skillfully used the principle of mirrors and the subtlety of the refractive angle of light, avoiding all the light refraction that might be put into his eyeballs. She's actually always there.

Strangely, the same set of mirror angle principles were vividly applied to the underground stone chamber, and the craftsmen who built this place obviously used some secret method to cleverly improve the principle of mirrors, and obtained the invisibility of a large range of real scenes. Moreover, it is in the subconscious of people that the mirror principle is brought into play.

I'm just thinking about something, how can I use any messy mirror principle here, it's not scientific at all. Zhu Beichen himself was confused, how could he think of the mirror, it couldn't be explained at all.

At this time, a gloomy word came from behind him, which immediately made Zhu Beichen's hair tremble and his body was cold.

"The four walls here are all mothers-in-law!"

'Mother-in-law', what is Mother-in-law? Obviously, after the Gu worm shattered, it triggered his infinite reverie, and even the cool yin qi blowing, he still maintained his composure.

Until this voice sounds, this, not the sound that three thousand should have. So, who is the person talking behind him?

He noticed the way the thing formed the word, it used 'here', which didn't look like the tone and words of a normal person's speech.

The four walls are all mother-in-law, what does this sentence refer to, there are people on all sides? Obviously, it won't be like this, he can't see anything at all, or perhaps, they are always there, but because of the different refraction angles of light, Zhu Beichen didn't find it.

In the darkness, the voice came again.

"Not every dream triggered by the Jade Spirit is the same"

What the! Zhu Beichen was startled, and he couldn't care about anything else, his eyes immediately opened, and there was a faint darkness in his eyes!
