A suffocating coercion instantly enveloped Chi Shui, a drop of sweat slipped from Chi Shui's sideburns, and countless thoughts of resistance and escape flew through her mind, all of which were rejected one by one.

The hand on her shoulder was not very strong, just lightly placed on her shoulder, but despite this, this terrifying aura still made Chi Shui's whole body feel as if he was bound by ten thousand snakes.

"Don't be nervous......," Chi Shui's voice sounded behind him, "Give me the Yin and Yang Origin, perhaps...... You don't have to die......"

"If you want to kill, you will kill! We don't have what you want! Chishui took a deep breath and said loudly.

"Hahahahaha......" A series of laughter shook the entire hall, "Little girl, the information I personally entered in the origin of yin and yang is only several times more than all the content on this planet, how can this kind of induction that seems to be a child right in front of me hide from me!" ”

Chi Shui was stunned for a moment and looked at Song Yufei, who did not have an expression of denial, it seemed that Song Yufei did have the origin of yin and yang.

Chi Shui shook her body and held the dragon horn knife in her hand, and before she could move her steps, a cold sword blade had already slanted down from her right head.

"Don't act rashly, the sword has no eyes...... "The voice behind Chishui sounded leisurely.

Chishui was anxious and shouted at Song Yufei: "Yufei! That's something very important to Lord Xuanyuan, don't give it to him! Let's fight with him......"

At this time, Song Yufei was constantly speculating about the other party's intentions:

According to the strength of the other party, it is not impossible to knock us down or kill, if we escape, it is almost impossible to do it, not to mention that we are in the underground of Li at this time, so why doesn't this person directly rob us?

Also, why did Lord Xuanyuan hand over such an important thing to me for safekeeping, when he knew that I would go deep into the Li Division...... It's hard......

It is difficult to be so easy that this yin and yang origin is so easily destroyed that the other party does not dare to act rashly, for fear that in the process of fighting, it will be destroyed by mistake, so that all previous efforts will be lost.

And Lord Xuanyuan did not destroy it early or personally, also because this thing is like a child's version of existence, and he has never been able to destroy it, or in other words, he can destroy it in front of this person in order to achieve the purpose of breaking his thoughts......

"Yufei!" Chi Shui shouted, Song Yufei was startled, and her eyes focused on her face.

Chishui smiled with tears in his eyes, and said softly, "Run!" After saying that, he swung the dragon horn knife violently and stabbed it at his chest.

Song Yufei was shocked and shouted, "Ah Xian...... No! ”

Just when the sword was less than an inch away from Chi Shui's chest, the dragon horn knife couldn't be pierced no matter what, and the blade of the long sword blocked the gauntlet of the dragon horn knife, standing still.

In a hurry, Chi Shui swung another dragon horn knife and wanted to repeat the old trick, but saw the long sword flip in front of her, clank twice, and the two dragon horn knives came out of their hands and landed between Song Yufei and Chi Shui.

"Hmph, don't worry! Your life and death are now up to me, Chiyou! ”

Sure enough, this person was Chi You, although Song Yufei had already made a certain number in his heart, he was still a little surprised when he heard the other party report his name.

It seems that Chi You has already made up his mind, planning to use this to blackmail Song Yufei to get the origin of yin and yang.

The air seemed to be frozen, a tear slowly slipped from the corner of Chi Shui's eyes, and Song Yufei on the opposite side didn't blink his eyes.

After a while, Song Yufei put his hand into his arms and took out the Yin and Yang Origin.

At this time, a smile appeared on Chi You's face: "Leave it to me!" ”

Song Yufei smiled bitterly, staring at the Yin and Yang Origin in his hand, his palms trembling slightly: "Just for this thing, countless living beings have lost their lives, just for this thing, the killing has not stopped, and the value of life is not as good as this information!" ”

Chiyou sneered: "Hmph! You won't understand, with this thing, you can become a god-like existence, a mustard life! It's not worth mentioning in front of the gods at all! ”

Song Yufei glanced up at Chi You, the latter's face was a little distorted, Song Yufei shook his head lightly, and the Yin and Yang Origin in his hand flashed a streamer: "If there is no life, then, what is the use of this thing!" ”

After speaking, he suddenly lifted the Heavenly Wind Thunder Spear in his hand and stabbed it fiercely at the Yin and Yang Origin.

Chiyou was shocked and burst into a shout: "Stop!" ”

A puff of dust swirled under his feet in an instant, and the figure disappeared in place, and the next moment, Chi You appeared above Song Yufei, already reaching out and preparing to snatch the origin of yin and yang.

And at this moment, the Heavenly Wind Thunder Spear in Song Yufei's hand flipped and stabbed at Chi You in the air, who was shocked and hurriedly sacrificed his long sword to stab back.

At the last moment, an unexpected scene happened, and a purple light appeared on Song Yufei's left wrist, and at the critical moment when Chi You's long sword was about to stab, the Yin and Yang Origin was raised high in front of him by Song Yufei.

"Ahh Chi You exclaimed, the voice had not yet fully come out, and the tip of the long sword had already touched the surface of the Yin and Yang Origin.

"Buzz......!"

A dazzling white light flashed, and the two closed their eyes at the same time, and when they opened their eyes again, everything around them changed, and the dark space was full of stars.

The two of them were suspended in the pitch-black sky, where there was no ground, no sky, no sound, and starry stars, reflecting an unbelievable picture.

The two of them are like two specks of dust in the vast, dark, and empty universe, looking extremely small, not only that, but the clothes of the two have also changed, except for the unchanged faces, there is nothing in their hands, and they are dressed in white, shining with a faint fluorescence.

Chi You was stunned for a moment, and waved his arm lightly, a kind of ethereal feeling, and he couldn't feel any power.

Song Yufei looked up at this pitch-black space, and a familiar feeling suddenly flashed in his heart, it was the mysterious starry sky found in that cave when he and Chishui were looking for the Xuantian Meteorite in the Xiuxun Mountain.

Song Yufei calmed down, his arms naturally drooped, his eyes stared at the changes in the starry sky, and gradually, the scene in the cave that day became clear.

A galaxy slowly emerged, and then the starlight gradually brightened, and the runes of attribute power began to appear.

In the starlight above, a plain metal rune has been revealed, and the other four corners only have faint fluctuations, but it can be seen that it should be the rune of Yi Shui, Shi Mu, Out of Fire, and Shi Tu.

Within the five directions, in the middle of the two runes, the thunder runes and the wind runes were also revealed, and even the ice condensing runes and the alchemy runes were clearly visible, so that only the middle of the ice condensing attribute runes and the thunder attribute runes was dark.

"Sure enough!" Song Yufei secretly said in his heart, "It is indeed five kinds of runes, and this last one is very important!" ”

Chi You also seemed to have discovered the mystery, not only the power of the two of them themselves was revealed here, but even the power of the attributes of the water condensation beads and heart refining beads inlaid on the two dragon horn knives that fell near Song Yufei just now were also revealed.

The unlit position also made him very concerned, it seems that the origin of yin and yang is by no means as simple as the two of them imagined, information entry is just an extremely simple function, and the secret inside is the key to the predecessors hidden here.

Chi You crossed his legs and stared at the position where the runes did not appear, the plain metal runes began to become dazzling, Chi You slowly closed his eyes, in this space, there is no point in fighting at all, how to understand the mystery of this rune starry sky is the most important thing.

Song Yufei also crossed his legs in the same way as Chi You, and in the dark air, the runes of the thunder attribute shone brightly with the runes of the Zephyr attribute, and the runes of the ice condensation attribute and the runes of the alchemy attribute were also much brighter than the four major rune civilizations in the outer circle.

Suddenly, Song Yufei's inspiration flashed, and his heart became nervous: the five runes in the outer circle and the five runes in the inner circle, no matter in terms of distance and size, have absolute rules, even if the rune that has not been lit up is lit up at this moment, in the area where the rune is imaged, there is at least one rune vacancy in the middle position.

"This!" Song Yufei exclaimed, but the sound did not come out of his mouth, and his ears did not receive any sound.

Song Yufei seemed to understand something, slowly closed his eyes, and began to comprehend, and the two runes of Thunder and Wind became dazzling as he began to comprehend.
