After a pause, everything was normal, and the stone slab with the word "rabbit" written on it under Bai Xiaoyi's feet also lit up.

Now that the right way to crack it has been found, the road behind it seems to be extremely smooth. Under the guidance of the arrogant wind, Bai Xiaoyi jumped on the word "dragon" again without hesitation. But in the next row, the scoundrel boy was stunned again, he turned around, and asked a little blankly:

"Brother Ao, how do you go in this fifth row? There is a blank space in the middle. ”

Laboriously looking towards the fifth row of the stone road, he said with arrogance:

"Listen to me, go to the blank one in the middle. The number in the middle of the nine-house chart is five, which does not correspond to any of the zodiac signs, so it must be blank. ”

Nodding, Bai Xiaoyi turned around and took a step without hesitation. But when he arrived at this position, it was a little difficult for Ao Cangfeng to see the contents on the slate. After hesitating for a long time, the young man with the sword said to the fox demon girl beside him:

"Miss Mei'er, we've determined that this move can break this mechanism. I'm going to go over now to help Xiao Yi look at the text behind, you follow me, you must not step on the wrong step. ”

Without waiting for the girl to answer, Ao Cangfeng stepped directly on the stone slab. Mei'er immediately followed, and in this way, a man and a woman quickly rushed behind Bai Xiaoyi, Ao Cangfeng held his shoulder, looked at it and said:

"The sixth row is 'Dogs, Monkeys, Pigs', and it's safe to step on dogs and pigs. Then there are chickens, then cows, and finally horses. Go all the way, trust me, that's right!"

With the support of his companions behind him, Bai Xiaoyi took a step without hesitation. After a while, the three of them passed smoothly through this dangerous stone road.

The next thing that appeared in front of the three of them was a huge bronze door. This huge bronze lump blocked the road in front of him tightly, and suddenly made Bai Xiaoyi and the others fall into a stalemate again.

This bronze door is completely poured into the stone wall of the underground palace, without a single rivet and half a gap, the only thing that can be found is the two cross cracks in the middle of the door that I don't know what kind of magic weapon was chopped out, and there are three strange discs on the left and right.

As a martial idiot, Ao Cangfeng naturally stared at the traces of the two chops. And Bai Xiaoyi and Hu Mei'er began to attack the discs on both sides.

The young man with the sword walked to the bronze door, touched the terrible scratches on the door, and said with some puzzlement:

"Judging by the depth and marks of this scratch, it should be a sword mark and not a knife mark. But the two crossed scratches that are so symmetrical are still arranged up and down, which always feels a little strange. It doesn't seem like it was left over from a break in a bronze door or a fight, but more like some kind of mark or ...... It's like ......"

Ao Cangfeng seemed to be for a long time, and he didn't say what it looked like. On the contrary, Bai Xiaoyi, who was on the side, suddenly interjected:

"Why do I think that these two ten forks are like the seal on the door when the house was raided?"

His words just hit the heart of the sword-bearer boy, and Ao Cangfeng immediately nodded and said:

"That's right, that's right, it's a seal. ”

As he spoke, he gestured back and forth with the giant sword in his hand on the scratches.

Bai Xiaoyi didn't bother to care what that guy was doing, he and Mei'er carefully inspected the six discs on the left and right.

The discs appear to be in groups of three, divided into left and right sides. The two outer discs each extend a groove pointing to the larger disc in the middle, while the two larger discs in the middle of the bronze door echo left and right, one on the left and one on the right, respectively with the symbols of "—" and "--".

The two of them twisted vigorously with their hands for a long time, and neither the disc nor the symbol in the middle moved for half a minute. This made Bai Xiaoyi and Mei'er a little difficult, and they each ran to the side and began to tinker with the two smaller discs on both sides. This touch, only to find that the small discs on both sides seem to be the key to open this bronze door.

There is a "= =" symbol on the four small discs on both sides, and the most ingenious thing is that this symbol is actually movable, although these four black strips can only be slid left and right, but it is obvious that these few things are the key to opening the door.

Curiously moving the four long strips of black stones, Bai Xiaoyi suddenly found that this thing was not a simple stone, but a magnet with magnetism. Once two stones come close, they will stick tightly together. The young man who discovered this phenomenon had a flash of inspiration in his mind, and he quickly ran to a place far away from the bronze door to observe the mechanism on the door with a complete perspective.

After a while, Bai Xiaoyi exclaimed in surprise:

"Come here, I think I know what this is!"

Hearing his exchange, Ao Cangfeng and Mei'er came over curiously. The young man with the sword asked suspiciously:

"Brother Bai, what did you find?"

Bai Xiaoyi pointed to the two crossed sword marks on the bronze door, and pretended to be mysterious:

"Look, what do those two things think?"

After hesitating for a long time, the fox demon girl said tentatively:

"Isn't that just two forks?

As she spoke, the girl took out the chip she was carrying and took a casual photo. Sure enough, there was no reaction on it.

Bai Xiaoyi shook his fingers and said with a cheap smile:

"No, guess again. ”

Ao Cangfeng groaned for a moment, and said uncertainly:

"A sealed spell?"

Bai Xiaoyi stroked his forehead, and said with some hatred:

"Didn't you notice that these two forks are actually the same word?"

"Words?"

Fox Mei'er asked a little stunned.

"Word ...... You mean...... 爻 (yáo)?!"

Ao Cangfeng's sentence is just to the point. Bai Xiaoyi patted him on the shoulder and said:

"That's right! It's still Brother Ao's extensive knowledge, which is the word that represents the gossip symbol!" As he spoke, the young man pointed to the two larger discs in the middle, and said confidently: "And the symbols on those two discs are the 'yang' and 'yin' that represent the yin and yang." ”

When he said this, Ao Cangfeng suddenly realized:

"I understand! The mechanism on this bronze door is actually what your Taoist sect often says, 'Taiji gives birth to two instruments, two instruments are divided into four images, and four elephants give birth to gossip'!"

snapping his fingers heavily, Bai Xiaoyi exclaimed excitedly:

"That's right! The key to opening the door is to adjust the magnets on the four small discs into the symbol of the four elephants!

Looking at the rogue boy's stinky fart, the fox demon girl sarcastically said disdainfully:

"Cut, what's stinky, I think you're blind. ”

Snorted provocatively, Bai Xiaoyi said proudly:

"Hmph! Don't look down on people, let me tell you, these things of yin and yang and five elements, I memorized them all when I was eight years old. Back then, I relied on these skills to get crows...... No...... It's not easy to say anything else, things related to metaphysics and Taoism can't help but strain me!"

kicked the ass of this arrogant boy, Mei'er scolded angrily:

"Enough is enough, why don't you open the door, this place is hot!"

Looking at the red faces of several people, especially the sweaty appearance of the girl, Bai Xiaoyi smiled wryly, and then immediately ran to the bronze door and fiddled with the magnet on the left disk.

He pondered for a moment, and then muttered to himself:

"On the left is 'Yang', which corresponds to 'Old Yang' and 'Shaoyin'. ”

Muttering as he adjusted the magnet inside the disc to the corresponding symbol. He glanced at the fox who was looking at the disc on the other side and was stunned, and commanded loudly:

"Sister Fairy, thank you, adjust the two discs on the other side into the pattern of 'Shaoyang' and 'Laoyin'!"

Blushing a little, the fox demon girl shouted with some annoyance:

"Idiot! This fairy doesn't know any yin and yang gossip, how do you know which is the young yang and which is the old yin!"

The corners of his mouth twitched, and Bai Xiaoyi said helplessly:

"Okay, okay, I'm scared of you. Shaoyang is a yang and a yin. Lao Yin is two Yin Yao, understand!"

Staring at the disc and thinking for a while, the fox demon girl followed Bai Xiaoyi's instructions and moved the magnet in her hand.

With a click, four small discs suddenly lit up as the last magnet returned to its place. Immediately after that, four streams of light flowed down the grooves in the bronze door to the two large discs in the middle, accompanied by a rumbling sound. In the middle of the bronze door, there was actually a symbol of the word "爻", and a dazzling white light burst out in an instant, and then the entire bronze door fell downward.

As the bronze door fell, a breath of fresh and cool air rushed out from the widening gap. All of a sudden, most of the burning sensation in this corridor dissipated in an instant. When the bronze door was completely sunk into the ground, a huge cave appeared in front of the three of them.
