The three killers saw Ye Xuan and the two of them appear, and their faces showed murderous expressions at the same time.

"Haha! They're here. The killer with the tiger stripes tattooed on his arm raised his long knife and shouted, "Hey, hurry up and come out obediently to die, and give you a good time!"

"It's to send you to death, to send you to death!"

A smile appeared at the corner of Ye Xuan's mouth, his hands pinched the trick to run the true yuan, and controlled the dragon bird sword up and down, the dragon bird sword hovered between his hands, and slowly rotated with the sword body as the axis, and the powerful power condensed on the sword body, making a sword roar.

"The double goods of the Yuanwu Realm dare to be ashamed here, let's try to see if I can block my sword first!" the tattooed tiger killer shouted, and immediately rushed up, and the long knife slashed straight down.

The other two felt the strong power accumulated on the Dragon Bird Sword, and when they saw that the Tattooed Tiger Youth had already made a move, they immediately drew their swords and followed.

Ye Xuan pointed out with a finger of his right hand, and the Dragon Sparrow Sword hummed, turning into a streamer of light, flying out at a speed that was difficult to see with the naked eye.

Boom!

Before anyone present could react, the Tiger Killer was shot through the chest with a sword and nailed to the wall.

The other two killers didn't expect this change at all, and were stunned for a moment.

There was only one thought left in their hearts, this sword trick was terrifying!

The four masters of the Yuan Martial Realm didn't even have a chance to react.

The Scar Killer was the first to react, and immediately manifested his martial spirit, pounced up, and slashed out with two swords, killing Ye Xuan.

Ye Xuan's body moved, and one leaned back to dodge the sword light, and rushed towards the Dragon Sparrow Sword.

The Scar Killer watched Ye Xuan rush past him and rush towards the terrifying flying sword, his eyes immediately widened, and he turned to the black-clothed killer and yelled, "Stop him! Don't let him touch that flying sword!"

The black-clothed killer also discovered the terrifying power of the opponent's sword, and hurriedly took out his sword to block it, but it was too late.

Ye Xuan's finger lightly touched the Dragon Sparrow Sword, and the true yuan poured into the sword, and the sword light flashed violently.

Sou!

The Dragon Sparrow Sword instantly pierced the chest of the black-clad killer.

The scar killer's eyes widened, and he felt the threat of death in his heart, and immediately looked back at Su Qixue, a fierce light flashed in his eyes, and immediately pounced, intending to catch Su Qixue and use it to save his life.

Su Qixue stepped back in panic, shrunk her neck, and closed her eyes tightly.

The speed of the Scar Killer was fast, but no matter how fast it was, it couldn't be faster than the flying sword, and his double knives had just reached Su Qixue's neck, and the sword light on his side flashed, piercing his waist ribs and nailing him to the wall.

The power of the Imperial Sword after the enhancement of the Divine Mind Creation Pill was so powerful, and it was effortless to kill the four opponents of the Yuan Martial Realm.

Ye Xuan raised his hand and grabbed the martial souls of the three killers into his palm, then walked up to Su Qixue, snapped his fingers and said, "Okay, it's been solved." ”

Su Qixue opened an eye, saw blood and corpses, her face suddenly turned pale, and she hurriedly covered her eyes with her hands.

Ye Xuan pulled out the Dragon Bird Sword, rubbed it clean on the corpse's clothes, and inserted it back into the sheath.

"Let's go. I'll send you to Sky City. ”

There is a terrifying yaksha in the next hall of the stars, and it is impossible to guarantee what will appear in the two dozen halls behind.

Ye Xuan didn't plan to continue exploring this underground building with a weak woman, if he wanted to explore, then wait until he saw her off, and then come back next time he was ready.

Su Qixue hesitated, looked back at the stone statue of the fire monkey in the hall of the house, and said, "Hmm...... In fact, there is also a formation mechanism on the stone statue. ”

"Huh?" Ye Xuan snorted suspiciously.

Su Qixue explained: "According to the position of the stars, in the central position of the twenty-eight constellation arch guards, there are also the Big Dipper, so in addition to the twenty-eight constellation halls in this underground building, there should be a Beidou hall in the center. Would you like to go inside and have a look?"

"Is there a way to open it?" Ye Xuan asked.

"You can give it a try. Su Qixue said and walked to the stone statue of the fire monkey and squatted down, pointed to the seven bronze pieces inlaid on the base, and explained, "These seven bronze pieces are not randomly decorated, all the way through, there are on the base of the stone statue in each hall." And I knocked it, and the sound was different. ”

As she spoke, she picked up a stone and knocked it on the seven bronze tablets in turn: "This is the palace, this is the Shang, the horn, the change sign, the sign, the feather, and the last one is the change palace." ”

"Rhythm. ”

Ye Xuan immediately knew what this was, the five tones of Gong Shangjiao's sign of Yu, plus the change sign and the change of the palace, a total of seven tones.

"That's right, the stars are divided into yin and yang and five elements, and the same is true of the seven laws. Therefore, if the bronze piece of the Seven Laws on the base is a mechanism, if it is knocked correctly, it is likely to open the Beidou Hall in the middle. ”

After Su Qixue finished speaking, she looked back at Ye Xuan and asked, "Do you want to open it and take a look?"

Ye Xuan thought for a moment before replying: "That's good, you tell me the sound and order that needs to be knocked, I'll knock, in case there is anything dangerous inside after opening the door, you can leave by yourself." ”

Su Qixue understood Ye Xuan's kindness, nodded silently, but did not go far, but stood in place and said the seven-law scale corresponding to the fire monkey.

Ye Xuan grabbed the scabbard and knocked it on the bronze plate.

Ding-ding-dong...... Ding-ding-dong......

After the knock, the whole hall was silent for a while, and then suddenly it shook.

The fiery monkey statue slowly moved forward, and the walls behind it slowly opened to both sides.

Ye Xuan took a step back and looked vigilantly at the slowly opening wall.

When the walls are fully opened, a more spacious hall emerges.

The floor of this hall is carved with a huge map of the Big Dipper, surrounded by formation pattern arches.

In the middle of the array, there is a stone platform, on which a thick book floats.

The moment Ye Xuan saw the book, he immediately knew that this must be a very valuable martial art or inheritance.

After confirming that there was no danger in this Beidou Hall, Ye Xuan took the lead in walking in.

Su Qixue also followed into the Beidou Hall and looked at the Beidou Hall seriously.

After the two of them walked into the Big Dipper Hall, the formation patterns on the ground slowly lit up, forming a golden hemispherical enchantment above the Big Dipper pattern, enveloping the book in the middle.

Ye Xuan picked up a stone and threw it towards the formation enchantment.

A golden lightning bolt shot out from the formation, instantly smashing the stone to pieces.

Seeing this, Ye Xuan couldn't help but swallow a mouthful of saliva.

At this time, in front of the formation enchantment, there was a rectangular stone platform, and a green jade guqin was placed on the stone platform.

Seeing this, Ye Xuan probably guessed that he must have used the rhythm to crack this formation enchantment.

You have to understand the formation, the stars, and the rhythm, which normal people can't enter.

Ye Xuan glanced back at Su Qixue.

Su Qixue smiled and said, "This place is really similar to what is said in "The Legend of the Array". ”

"Can you play the piano?"

"Yes, if you can't learn the piano well, you won't be able to read other idle books. Su Qixue said and sat down in front of the guqin and tried to pluck the strings, "This is really a good piano, I don't know how long it has been played, but the sound is still the same." ”

She said to herself, and slowly began to play.

The sound of the piano is melodious and beautiful.

But it's not the sound of the piano to crack the formation, but a piano song that comes from feeling.

In the golden hall, a beautiful woman strokes the piano with her hands, and the sound of the piano is curling, as if it is a beautiful picture, imprinted in the bottom of the eye.
