In the past ten years, the entire back mountain seems to be shrouded in the destructive breath of karma, and all the plants and trees have withered with it, looking empty, and everywhere is filled with the smell of dead silence, without a trace of life.

Not far away, the ball of light that seemed to be infected with ink was still standing there, like a gap in space, which was terrifying.

However, at this moment, on the surface of the inky ball of light, a trace of gray crack appeared, as thin as a hair, but it was spreading at an alarming speed.

"Whew~!" "Whew~!" "Whew~!"

Several figures appeared out of thin air around the inky ball of light, and everyone looked at the gradually shattering ball of light, their hearts beating faster, and their breathing became sluggish.

No one dared to make a sound, as if they were afraid of affecting the transformation process.

Click...... Click......!

The crisp cracking sound sounded one after another, and the faint gray light streaks instantly covered the entire ball of light, flickering and dimming, as if it was secretly in line with some special rhythm, and the ball of light was also constantly undulating.

"Whew~!"

Suddenly, there was a heavy breathing sound from the ball of light.

In an instant, everyone's tense heartstrings were loosened by half, at least it could be judged that Zhou Jiuhui was still alive and had not been eaten by karma because of his transformation.

At this moment, Lan Jun heard the familiar sound of breathing, and tears fell involuntarily, and his expression was extremely excited.

"Po~!"

The ink-colored sphere covered with gray light streaks shattered, and the endless gray mist surged and filled the sky, instantly forming a canopy with a radius of thousands of meters, enveloping the entire back mountain, and the gray air flow swept every inch of space, but it was filled with a palpitating atmosphere.

A breath of pure destruction, as if capable of devouring everything.

The Demon Land suddenly felt bad, and immediately the True Yuan agitated, and the vast True Yuan Power like a river and sea instantly enveloped everyone, but the moment it touched the gray light mist, it shattered again.

Today's Demon Land is already a master of surviving the Eighth Heavenly Tribulation, and the strength of its true yuan is rare in the entire world.

However, at this moment, his sturdy True Yuan was like tissue paper at this moment, and it was instantly crushed by this gray light mist.

At this moment, the face of the demon land suddenly became extremely pale.

"All stand back!" Sun Wukong roared, the Yuan Shen came out of his body, and the 'Thief Saint' instantly appeared in the void, and the endless power of decomposition emerged, entangled with the gray light mist.

"What a strange power!" Sun Wukong's brows also furrowed deeply, he felt that the destructive power contained in the gray light mist seemed to be endless, and there was an irresistible feeling, if it weren't for his own Yuan Shen out of his body, I am afraid that all the people present would be crushed by this force.

At this moment, in the gray airflow, a figure attracted everyone's attention.

The man was half-bowed, like a wounded beast, and his breathing was unusually heavy.

"Big stupid!" Lan Jun couldn't help but call out, she desperately wanted to see Zhou Jiuhui.

Ten years of lovesickness, who can understand?

Under the shroud of gray light and mist, Zhou Jiuhui's divine consciousness was still in the inner world of the Supreme Demon Yuan.

..............................................................................

In the vast and boundless evil land, Zhou Jiuhui looked up at the huge black and white vortex in the sky, and the endless gray air currents were surging in the space.

"It's been 10 years...... It's finally done. Zhou Jiuhui took a deep breath, and his eyes showed a look of relief.

In the Demon Temple, the gloomy voice of the Demon God came: "After ten years of transformation, this karma has finally evolved......... What do you feel from this power?"

Zhou Jiuhui's eyes narrowed, and he said in a deep voice: "Destruction...... I could feel the endless aura of destruction contained in this gray energy, it was amazing. Could it be that this is what the mysterious powerhouse called 'Netherworld Battle Ability'?"

"Now that you are an existence far beyond the Ninth Great Tribulation, I'm afraid this human realm can no longer tolerate you. ”

Zhou Jiuhui smiled indifferently and said slowly: "Do you want to say that you will ascend to the immortal realm?"

Zhou Jiuhui flipped it with one hand, and the endless gray light mist instantly condensed in the palm of his hand, forming a fist-sized gray ball of light, exuding an obscure dark light, but the aura of destruction contained in it was so amazing.

"I didn't expect it...... Karma will eventually evolve into this gray energy, and I think this should be the ultimate realm of the 'Heavenly Rune'. ”

In the past ten years, in that inky ball of light, Zhou Jiuhui has been cultivating the 'Heavenly Rune' as always, but at the same time, karma is also constantly evolving, and it is not until this gray destructive energy completely replaces karma that this transformation process is completely completed.

The demon god said meaningfully, "Now it's time for you to go back too......... Think about when you will leave the human world. ”

Zhou Jiuhui frowned slightly, and the next moment his consciousness returned to his body, his eyes gradually opened, but what he saw was a gray world.

Not far away, the 'Thief Saint' exerted the power of decomposition, resisting the invasion of this gray energy.

At this moment, Zhou Jiuhui suddenly felt that the gray energy deposited inside the dantian was pouring into the limbs and hundreds of bones at an astonishing speed, whether it was the body or the soul, it seemed that some kind of qualitative change had taken place at this moment, and it was completely transformed with the invasion of gray energy, and it became even stronger.

After about a stick of incense, this process of qualitative change gradually ended.

At this moment, a trace of gray light suddenly appeared on the surface of Zhou Jiuhui's skin, staggered and horizontal, sweeping the whole body, but it disappeared in an instant.

Zhou Jiuhui let out a long breath, and with a flick of one hand, the gray mist that enveloped the entire back mountain was suddenly controlled by an invisible spell, gathered in Zhou Jiuhui's palm, and finally returned to the inside of his body from the palm of his hand.

With this gray energy, Zhou Jiuhui seemed to feel a sense of control that was almost emperor, as if anyone in his eyes was small and could be ignored.

"Your Excellency!"

"Jiuhui!"

"Big fool!"

Before she could react, Lan Jun was the first to pounce, and Zhou Jiuhui took advantage of the situation to hug her tightly into his arms and said softly: "Jun'er, I'm sorry." ”

At this moment, Lan Jun was already crying, and only hugged Zhou Jiuhui tightly.

Seeing this scene, Sun Wukong smiled indifferently, included the 'Thief Saint' in the True Yuan, walked over with everyone, and said, "In the past ten years, you can make us wait." ”

Zhou Jiuhui looked at everyone and said with a somewhat embarrassed smile: "I didn't expect that there would be a sudden transformation when I was cultivating, which was purely unexpected, hehe." ”

Suddenly, a cheer of surprise sounded, everyone seemed extremely excited, and tears even welled up in the eyes of the Heavenly Demon Shuangwei.

Demon Land hurriedly said, "Supreme Master, how has your cultivation been in the past ten years?"

Zhou Jiuhui smiled indifferently, stretched out his palm, and suddenly a fist-sized gray energy emerged, and a strong aura of destruction once again swept through the entire back mountain.

"It seems that the cultivation of the 'Heavenly Rune' has reached the limit over the years, but the karma has also evolved to form this new power, as for the internal mystery of this power, I can't explore it in my current realm, but what is certain is that I have now reached the realm of ascension. ”

The exclamation sounded again, and the powerful, special destructive power shocked everyone.

Sun Wukong walked to Zhou Jiuhui's side, put his hand on his shoulder, and couldn't help but change his face greatly, and exclaimed: "It's really amazing, the strength of both the body and the soul has been greatly improved, it's really strong." ”

Through 'stealing the heavenly hand', Sun Wukong clearly felt that Zhou Jiuhui now was already the same as ten years ago.

Zhou Jiuhui closed his eyes slightly, feeling his soul.

Inside the body, the soul originally existed in the form of cyan mist, permeating the entire body, but at this moment, the mist condensed, forming a more substantial sphere, and the color also evolved into gray, just suspended above the dantian, and the outside was shrouded in a hazy light mist, which looked particularly weird, but gave people an extremely solid feeling.

The abnormal change of the soul, this point Zhou Jiuhui did not feel novel, because all the cultivators had the strength to survive the Ninth Heavenly Tribulation, and their souls would change.

But six hundred years ago, Zhou Jiuhui's soul had already changed once.

However, for the qualitative change of the physical body, Zhou Jiuhui felt extremely surprised.

For cultivators, as the true yuan gradually stabilizes and strengthens, that trace of true yuan power flows through the limbs and hundreds of remains, and at the same time, it is also constantly infiltrating into the muscles and bloodlines, gradually strengthening the physical body.

Due to falling into the six realms of reincarnation nine times, Zhou Jiuhui's body was constantly reshaped, even if he had the Supreme Demon Yuan, there was still a certain gap between him and the masters like Zu Wu and He Qianlang who had survived the Ninth Heavenly Tribulation in terms of the defense of the body.

However, at this moment, after the transformation of gray energy, Zhou Jiuhui clearly felt that the strength of his physical body was greatly improved, and even approached the immortal body of Gao Wanfei.

'Rune of Heaven'...... Karma ...... Gray energy, all the evolution looks strange and weird, but it seems to be gradually changing according to some rules.
