Chapter 623 Becoming the Demon King

There are steep mountains and steep peaks, and there is light mist under the cliffs.

This is an unknown valley, desolate and deserted, but it is like a fairyland outside the world. The aura of heaven and earth here is extremely rich, and you can feel a kind of coolness at your fingertips.

After Yun Yi killed Zhang Xun and Dugu Ming, he fluttered his wings and came here. The power of his soul was powerful and he had already explored it. There was not a single person or even a monster within a hundred miles of this place.

"Auspicious clouds hang over the ceiling, full of spiritual energy. It is really a good place. It is a pity. If it were in the Eastern Wasteland, such a place would be enough to build a peerless sect."

Yun Yi sighed endlessly. He enjoyed the coolness here, then found a big stone and sat down cross-legged.

Heifeng was lying aside in a daze. Golden air began to fill his body. His aura was undergoing great changes. Yun Yi could even feel the rippling power of the space around Heifeng.

"Heifeng is going to be promoted to Spirit King. Has this guy realized the power of space so quickly?"

Yun Yi was sighing, and even felt a sense of frustration, because from Yixiantian to Spirit King, the most important thing is not the accumulation of energy, but the understanding of the power of space. Only by being able to control space can one become king.

He claims to be a unique genius, but he has no clue about the power of space. However, Black Wind, a divine beast, realized the power of space while lying down and sleeping.

"wrong."

However, Yun Yi soon discovered something was wrong with Heifeng. Although he had not comprehended the power of space, he could clearly distinguish the process of space comprehension. The power of space rippling outside Heifeng's body seemed to be related to the power of space. Innately the same.

It feels like Heifeng himself has understood the power of space and cannot become the king, just because he cannot reach the energy of the king. Now that the energy has been achieved, he will naturally become the king.

"This guy must have a secret."

Yun Yi secretly thought, but he didn't care about this. What he cared about was Heifeng's progress. Heifeng could be promoted to Demon King in advance. This was a good thing for him. A Demon King at the level of a mythical beast would be a good thing. The huge help that stocks can’t imagine.

Buzzing…

Suddenly, outside Heifeng's body, the power of space began to become manic, and the golden energy was also restless, flickering, and it seemed that it might be extinguished at any time.

"Heifeng, what's going on?"

Yun Yi said, and used his spiritual thoughts to attack Hei Feng, directly waking up Hei Feng.

"What the hell, even though I ate the Red Heavenly Snake, I still don't have enough energy. Now I'm in an important stage of attacking the Demon King. If I fail, I will definitely suffer some backlash."

Black Wind couldn't help but curse.

Hearing this, Yun Yi breathed a sigh of relief. If it was just that the energy was not enough, it would be easy to solve.

With almost no hesitation, Yun Yi directly took out the demon spirit of the Scarlet-trained Heavenly Snake and put it into Hei Feng's mouth.

Heifeng knew his state, so he was not polite to Yun Yi. He swallowed the demon spirit of the Red Heavenly Snake. The golden energy that was flickering became stable in an instant, and the power of space made a chi chi sound. sound.

"Is it enough?"

Yun Yi asked. He already had the snake gall of the Red-trained Heavenly Snake in his hand. If Hei Feng's energy was not enough, he would put the snake gall into Hei Feng's mouth without hesitation.

Compared with his brothers, these treasures were all external possessions and became worthless in Yun Yi's eyes.

"That's enough. Keep the snake gallbladder. It will be of great use to you."

Heifeng said, the most precious treasure of the Red-trained Heavenly Snake is the snake gallbladder, not the demon spirit.

Yun Yi nodded and put away the snake gallbladder. He originally planned to refine the snake gallbladder immediately, but now Black Wind is at the most critical moment. Yun Yi didn't want any accidents to happen, so he put aside the matter of refining the snake gallbladder. , the power of his soul spread, covering almost the entire valley.

Yun Yi is Heifeng's protector. He will wait until Heifeng is completely promoted to the Demon King before he can start refining snake gallbladder. At that time, Heifeng can protect him.

Half an hour later, a huge golden cocoon formed outside Heifeng's body. The powerful energy shook the entire valley. The power of space made a thunderous sound, which simply caused some strange phenomena.

The commotion here began to become louder. The birth of a demon king was not only earth-shattering, but the aftermath that rippled out was shocking enough.

What's more, a guy as arrogant as Heifeng will not cover up his energy once he is promoted.

"Don't alert others then."

Yun Yi secretly thought, and then jumped up. He kept forming seals with his hands, creating a series of restrictions, forming a large formation above the entire valley, hiding all the auras in the entire valley.

This kind of formation is completely easy for Yun Yi now, no problem. After all, Yuan Formation Heavenly Book is no joke, and Yun Yi's current strength is also strong. Although he has not yet reached the level of Spirit King, he can already do it. Kill the Spirit King.

Another moment passed.

Roar……

Hei Feng, who was sleeping, suddenly let out an earth-shattering roar. Hei Feng, who was lying on the big rock, suddenly flew into the sky. His body changed, and in an instant he was more than ten feet in size.

The nine tails surged, and the powerful momentum nearly crushed the void.

The golden light filled the air, and Yun Yi couldn't help but marvel every time he saw Heifeng transform. He thought of what the Jiuyang Holy Fire Beast said when he saw Heifeng transforming. Heifeng's bloodline is probably better than the legendary Jiuyang. The tailed cat is stronger, a powerful alien species from ancient times.

"Wow quack..."

The black wind swirled back and forth in the sky, reaching the extreme level of arrogance. It was so joyful that Yun Yi couldn't help but hold his head.

This guy who loves to show off has no regard for their current situation. Yun Yi is almost the enemy of everyone in the world. Everyone in the ancient city except the Yanwu family and the Qin family want to kill him. At this time, he doesn't know how to keep a low profile, too. drunk.

Fortunately, Yun Yi had the foresight to set up a large formation in the sky in advance, covering everything here. Even if a small amount of energy rippled out, it didn't matter, at least he wouldn't attract the enemy.

Heifeng excitedly spun around in the sky for more than a dozen times before he calmed down his momentum and turned into a kitten and fell from the sky.

"It's cool, I'm also the demon king now, let's see who dares to mess with me."

Hei Feng was arrogant, looking like he was dissatisfied with everyone and extremely in need of a beating.

"Yes, you have accumulated a lot of experience. It seems that the Red Heavenly Snake has helped you a lot. Not only has you been promoted to the Demon King, but your cultivation has also been completely stabilized at the level of the first-level Demon King."

Yun Yi nodded, very happy for Hei Feng.

"By the way, when will your catastrophe come?"

Yun Yi asked curiously, a divine beast like Black Wind will definitely suffer from heavenly calamity. After all, even the Nine Sun Sacred Fire Beast has calamity.

"Master Cat has no catastrophe."

Heifeng said that there was no heavenly calamity, but Yun Yi was stunned again.
