The pace that was supposed to be moving forward suddenly stopped, and he took two steps back.

Nie Fan and the others looked at Killing Heaven suspiciously.

"The root of the yellow sky is yours, I won't try. Killing Heaven said helplessly, but the sincerity in his eyes made Nie Fan understand that Killing Heaven's heart was closer to the three of them.

He has lived for hundreds of thousands of years, and he has already seen through many things, just like friendship, and many times, some close friends on weekdays are likely to stab you in the back.

But now the Killing Heaven still believes in friendship.

"Go ahead, good haode fusion, once the fusion is successful, you will be eligible to activate the shijie seed. The voice of killing the sky was a little lonely, but his heart was much lighter at this moment.

He was used to killing, his heart was originally dark, but as he got along with Nie Fan and the others for so long, he slowly began to change.

"Give!"

Xiaoxiao took out a jar of wine and threw it directly to Killing Heaven, who was not verbose, and directly slapped open the sealing mud and poured a few big mouthfuls on his head.

"Go ahead, we'll be waiting for you outside. Killing Heaven whispered.

Nie Fan nodded slightly and no longer hesitated, this Yellow Sky Root is a Heaven and Earth Treasure, and even the Yuan Emperor monks will compete for it, so the preciousness of the Yellow Sky Root can naturally be seen.

Nie Fan walked into the ancient tower filled with chaotic qi, and then a circle of purple qi around his body slowly emerged.

Looking at the root of the ancient shijie tree, which is the root of the yellow sky, Nie Fan's heartbeat at this time also increased slightly, and anyone who saw such a rebellious treasure would have a faster heartbeat.

It is definitely the dream of any monk to create a real shijie and be a master of shijie, but in the end, there is no one who can do it.

Millions of years have passed through the ages, but there is no existence that can truly cultivate a perfect shijie, and perhaps only the legendary god-level monk can truly reach that realm.

The battle between the Yuan Emperor monks is based on the strength of the power of the perception shijie, and every blow is earth-shattering, and they can subvert this heaven and earth, because they have already controlled the true origin power of this shijie!

The power of Shijie's origin is that the power of Shijie is above the power of order and the power of rules, but there are not many monks who can truly perceive the power of Shijie throughout the ages.

Nie Fan walked into this ancient tower with the help of purple qi, the broken ancient tower was wrapped in chaotic qi, and Nie Fan came to the root of the yellow sky after an hour, and then Nie Fan directly leaned out of his palm, and the purple qi was filled with purple qi.

The chaotic qi was extremely heavy, even if Nie Fan's palm was covered with purple qi, it was also a little unbearable, because the purple qi under Nie Fan's control was still too little.

The purple qi is extremely mysterious, as for the true origin, Nie Fan is not clear, but Nie Fan knows that after so many years, this purple qi can penetrate anything, including attacks and barriers.

As for what kind of characteristics the Xuanhuang Qi at the same level as the Chaos Qi possessed, Nie Fan didn't know, but thinking about it, that characteristic was also terrifying.

With the help of purple qi, Nie Fan finally incorporated this Yellow Sky Root into the Divine Bead after a day, a dead wood with a radius of about one meter, but it exuded a rich chaotic qi, and it was this purple space, and with the appearance of this Yellow Sky Root, there were also subtle cracks.

This made Nie Fan very shocked, but with the surge of purple qi, the cracks were also slowly healing, and there were not many ancient tree roots, but it gave people the feeling that it was as if this Yellow Sky Root came from that unknown ancient world, as if this tree root existed when the heavens and earth first opened.

"Fusion. ”

Nie Fan was not long-winded, the devouring energy appeared, and the Immortal Demon Book ran and a huge black hole directly transformed out, and began to go towards the ancient Yellow Sky Root.

Crack, but as this black vortex touched the root of the tree, this black vortex disappeared silently, which shocked Nie Fan very much, for so many years, the combination of devouring energy and immortal demon canon has been invincible and has never failed, but this moment seems to be useless for this root of the yellow sky.

Nie Fan tried again, but it was still the same.

The black vortex appeared, and at this moment, Nie Fan directly operated the devouring energy, but did not run the Immortal Demon Codex, Nie Fan always had a feeling that the combination of these two terrifying ** would be resistant to this Yellow Sky Root.

However, the black vortex was completely formed by devouring energy, but once it touched the root of the yellow sky, it still could not be swallowed and disappeared directly.

"This. Nie Fan suddenly had a feeling that he didn't know where to start.

"The Immortal Demon Book was obtained by Ye Yu from the thousand-year-old Heavenly Cave, and I don't know how much energy he has helped Nie Fan refine over the years. ”

At this moment, Nie Fan closed his eyes, and the next moment, Nie Fan's hands slowly slid out of an incomprehensible trajectory, and then two black silk threads shot out of Nie Fan's hands, and as soon as the black silk threads appeared, an incomprehensible aura erupted.

The ancient breath is spreading, the ancient breath is **, and the aura emitted by Nie Fan's black silk threads is actually so ancient.

Over the years, Nie Fan has almost always run the Immortal Demon Book with Eater Energy, and now Nie Fan has almost forgotten the breath of the Immortal Demon Codex.

At this moment, Nie Fan ran the Immortal Demon Book alone, and suddenly felt an indescribable feeling, which felt like he could refine everything in the world.

Immortal Demon Codex,Immortal Demon This is a very evil synonym.,Immortal Demon is an opposing existence, but there doesn't seem to be such an existence in the legend.。

Of course, Nie Fan couldn't think of these at this time, if there were really immortals and demons, then thinking that the existence of that level would definitely be able to compete with god-level monks.

It's just speculation, and no one knows what the real situation is.

The black silk threads quickly wrapped the root of the yellow sky, and at this moment, the black silk threads did not disappear, which made Nie Fan suddenly overjoyed.

In an instant, the Immortal Demon Book was running, and suddenly, a powerful refining power suddenly came out, and the next moment, Nie Fan let out a low roar, and directly stuck his palms on the root of the yellow sky.

Black silk threads continued to surge out of Nie Fan's palms, and at this moment, Nie Fan's eyes looked a little crazy, and the terrifying aura was also stirred up at this moment.

The purple qi wanted to rush into Nie Fan's body, but it was dispersed by the chaotic qi, and at this moment, Nie Fan really realized that this purple qi level should be equal to the chaotic qi, Xuanhuang qi, and the three kinds of heaven and earth qi, otherwise, it would be absolutely impossible for this chaotic qi to disperse the purple qi.

An hour later, Nie Fan's eyes were closed, and a quiet look appeared on his face, and a gray air flow flowed out from the Yellow Sky Root, and at the same time, the Yellow Sky Root also began to show subtle changes.

Time began to flow rapidly at this moment, and half a year passed in the blink of an eye.

In half a year, the root of the yellow sky was also slowly shrinking, on the contrary, a more and more brilliant turquoise seed appeared in Nie Fan's dantian, and the strange veins on this turquoise seed were also flashing and flashing, looking mysterious and unpredictable, and there were wisps of subtle chaotic qi!

A year later, Nie Fan opened his eyes, and the Yellow Sky Root in the purple space also disappeared, and a fist-sized seed appeared in Nie Fan's dantian, and an ancient wood imprint on it.
