In the main hall, Ye Mu came to the dragon chair, and the pattern of the hexagonal evil spirit on it was still vivid, revealing an evil aura.

Sitting cross-legged on the ground, Ye Mu carefully looked at the small golden box in front of him, but he didn't find any clues, Xi Yun's faint voice came out: "Don't be in a hurry to open it, to prevent there from being trapped!"

Hearing this, Ye Mu said softly: "Sister Yun, you can rest first, and when you recover a little, we will study this box together." ”

Xi Yun continued to be silent, Ye Mu put the small golden box aside, reached out and picked up the long sword, the texture felt like a stone, but the feel was extremely light.

"What kind of material is this made of?I can't tell its grade at all, it must not be lower than the star grade......" Ye Mu looked at the long sword and muttered slightly.

The long sword has no scabbard, and there is a triangular pattern on the hilt, from which the evil spirit smoke seeped out before, what does this mean? Ye Mu didn't know.

After carefully investigating for ten minutes, Ye Mu frowned and muttered, "I didn't find anything, and there is no evil power in this long sword......

Nothing was found, Ye Mu had no choice but to give up, close his eyes and enter the cultivation state, and quietly wait for Xi Yun's recovery, which was half a month.

It has been two months since Ye Mu entered the Star Sea Trial, and if you want to say that there is no gain at all, it is too absolute, at least your cultivation has improved a little.

Xi Yun was almost recovered, and the Shadow Sword circled around the small golden box a few times, as if trying to see the mystery contained in it.

Ye Mu looked up at the dragon chair on the high platform of the main hall, who was the man with six horns? was he alive or dead? According to the number of horns, his status in the Outer Heaven was absolutely extremely high.

"Could it be that he is the lord of the Outer Domain, the ruler of the Extraterrestrial Evil Clan?" Ye Mu suddenly had such a thought in his heart, and Xi Yun's words interrupted him.

"This little golden box may contain the most valuable thing in this tomb palace, but it is difficult to open it. ”

Ye Mu looked at it when he heard the sound, pointed to the small golden box and asked, "This box is covered with forbidden patterns, but I can't feel a trace of evil power, isn't this thing from the Outer Heavens?"

Xi Yun was silent for a moment and then said: "It's possible, but if you want to open it, you must first erase these forbidden patterns, and forcibly breaking them may destroy the things in them." ”

Ye Mu squinted slightly, and a wisp of sword qi appeared on the tips of his fingers, like a thin veil slowly covering the small golden box, and the forbidden pattern on it began to squirm as if it had come to life in an instant.

"It's ......"

Xi Yun pondered for a moment, and then said, "Is this a resonance, or is it a prohibition?"

Ye Mu sensed that he had a wonderful connection with the golden small box at this moment, but he couldn't say it clearly, suddenly, the Xuan Qi in his body gushed out unguidedly and converged into the small box.

"Buzz!"

A strange scene happened, the golden box burst out with dazzling golden light, Ye Mu couldn't help but raise his hand to cover his eyes, and in the next second, the wonderful connection disappeared.

It wasn't until Xi Yun's reminder that Ye Mu slowly opened his eyes, and the small golden box in front of him returned to its previous appearance, but the complex forbidden pattern on it disappeared out of thin air.

"What's going on?" Ye Mu raised his eyebrows slightly, looked at the Shadow Sword and asked suspiciously.

Xi Yun replied lightly: "I don't know, it seems that it is the influence of your wisp of sword qi, and the forbidden pattern has been broken crookedly." ”

Ye Mu looked back at the small golden box, and was about to reach out to touch it, but suddenly retracted violently, because the small box opened by itself.

The Xuan Qi gushed out from all over his body, and a Xuan Qi light shield was placed in front of him, Ye Mu raised his defense to the extreme, but found that there was nothing coming out of the small box.

"Isn't there a mechanism...... Ye Mu muttered slightly, his eyes looked at the inside of the small golden box, but he only saw a black scroll tied with a red ribbon.

"Could it be ......" Ye Mu's eyes widened violently, and he said happily: "It won't be the Imperial Sword Technique!"

But in the next second, Ye Mu calmed down again, the information of Tianji Pavilion had already been said in detail, the eighth volume of the Imperial Sword Technique was in the hands of the Antarctic Emperor Nangong Han, and the ninth volume was going to the Jade Sword Immortal Mountain, so this could not be the Imperial Sword Technique.

Without physical contact, Ye Mu raised his palm, and a suction force gushed out, taking out the black scroll in the small golden box.

The soft sword light crossed the red ribbon, the scroll spread out, Ye Mu was stunned, and the four slightly ancient words were scarlet and conspicuous: Sword Thunder Prison Codex!

The Shadow Sword was suspended, and Xi Yun said slowly: "Is this a kendo mystical technique? or a kendo technique? This shouldn't be a thing from the Outer Heavens!"

Ye Mu came back to his senses, carefully looked at the words and patterns recorded in the scroll, and suddenly remembered the strange scene that appeared in his mind when he first saw the sword coffin.

"This sword code is the source method that urges the sword of thunder and lightning?" Ye Mu's eyes turned, and he speculated in his heart, and suddenly the text patterns on the scroll emitted brilliance, falling off from the scroll one by one, turning into streamers and rushing into Ye Mu's eyebrows.

"Not good!" Xi Yun's worried voice came out, but it was already too late, Ye Mu's whole person froze, and the scene in his eyes changed again, turning into a thunder prison.

Countless extraterritorial evil clans were pierced by the endless thunder and lightning sword in the void, and the ground turned into purgatory, and the cage formed by the thunder sword trapped the evil creatures, making them suffer from the power of thunder.

As soon as the picture turned, a powerful evil creature with a hexagonal head holding a fire sword slashed out a flame channel, breaking through the thunder and lightning sword prison and rescuing some extraterritorial evil creatures.

The picture came to an abrupt end, Ye Mu's body trembled, blinked, and involuntarily looked up at the dragon chair above the main hall, the man on the pattern was the huge evil creature holding the fire sword in the scene.

"Ye Mu, how are you? Are you okay?" Xi Yun's shout made Ye Mu come to his senses, and immediately smiled: "Sister Yun, don't worry, I'm fine." ”

"What the hell is going on? The information of the Sword Code poured into your body, and you didn't notice anything unusual, right?"

In the face of Xi Yun's doubts, Ye Mu briefly said what had just happened, and the former muttered: "Could this be a choice of masters? But this sword book has no spiritual wisdom, which is very strange." ”

Ye Mu's mind flashed the information of the Sword Thunder Prison Codex, and after browsing it, he couldn't help but smile slightly: "I have mastered a huge killing move, as long as I master this Nine Swords Thunder Prison Technique, even if I am a powerhouse in the late stage of the Spirit Xuan Realm, I am sure of winning." ”

Hearing this, Xi Yun muttered, "This is a sword skill, then this harvest is huge, and it is not worth this trip to the Star Sea Trial." ”

Ye Mu shook his head slightly and said: "The Nine Swords Thunder Prison Technique in this Sword Classic, strictly speaking, is a combination of sword formation and sword technique, with great lethality and a wide range of attacks, but it is extremely difficult to succeed in cultivation. ”

Xi Yun smiled and said, "What are you afraid of? You don't have confidence in yourself? Sister is optimistic about you, and you will definitely be able to succeed in cultivation." ”

Hearing this, Ye Mu smiled indifferently, looked around, and said, "Why is there such a dragon chair in this ancient tomb palace? ”

Xi Yun said lightly: "Don't think about it so much, let's leave here first and find a place to practice this Nine Swords Thunder Prison Technique!"

Ye Mu left the tomb palace and also left the island, and did not continue to go deeper, but flew to the side.

If he continued to go deeper, Ye Mu was worried that he would encounter other extraterritorial evil clans, which would not be good, and the most important thing at the moment was to find a secret place to practice the Nine Swords Thunder Prison Technique he had just obtained.

A few hours later, Ye Mu came to a starry sky island, there was no trace of previous visits, and the environment was good, the surroundings were very empty, if someone came, they could immediately notice it.

On the island, Ye Mu found a low-lying position and began to cultivate the Nine Swords Thunder Hell Technique, the cultivation of this sword technique has a relatively harsh condition, and gradually the cultivation of people must reach the Lingxuan realm, and secondly, they must master the sword realm above the sword body.

Mastering these two points at the same time is undoubtedly very harsh, but Ye Mu barely complied, and the information about the Sword Thunder Prison Code in his heart emerged one by one, and a trace of brilliance patterns appeared on his body.

The shadow sword on the side was quietly suspended, doing the work of protecting Ye Mu and observing the movements around him, Xi Yun muttered in a low voice: "This sword trick is not bad, why haven't I seen it with my master before, or even heard it, such a sword trick shouldn't be famous......

"Buzz!"

A powerful aura suddenly swept out of Ye Mu's body, and above his head, a thundercloud appeared, and there was a flash of thunder.

"Zizizi!"

The thunderclouds surged one after another, and the thunder slashed down, right in the middle of Ye Mutianlinggai, but it didn't hurt him, and the thunder seemed to be absorbed.

In Ye Mu's body, a stream of thunder and lightning was shuttling, but it did not cause harm to the meridians around the body, running Zhou Tian like Xuan Qi, and finally converged into the Xuan Qi Sea.

Witnessing this scene, Xi Yun couldn't help but be a little surprised, and said to herself, "What's the situation?

The thundercloud above Ye Mu's head once again split a wisp of thunder, and the result was the same as before, the thunder and lightning converged into the Xuan Qi Sea after the meridians in his body ran for a week.

This scene lasted for a month, Ye Mu was like an old monk in a fixed place, motionless, and this starry sky island only had the sound of thunder constantly rolling.

It had been three and a half months since he came to the Star Sea Trial, and Ye Mu opened his eyes, and two rays of lightning shot out, as if they were going to pierce the starry sky.

The thunderclouds above his head slowly dissipated, Ye Mu breathed a long sigh of relief, and Xi Yun hurriedly asked, "How is it?"

Ye Mu pursed his lips and shook his head: "How can it be so easy, now it's just a beginner, and not even a trace of sword and thunder qi can be condensed." ”

"Sword and Thunder Qi?" Xiyun wondered, "What do you mean?"

Ye Mu stood up and explained: "The sword and thunder qi is like the Xuan Qi, if you want to perform the Nine Swords Thunder Prison Technique, you need to condense the sword and thunder qi, and then condense it into a thunder and lightning sword. ”

The simple explanation made Xi Yun understand that the cultivation of this sword technique could not be successful in just a few months, and it would take a lot of time and energy.
