From time to time, Yisheng laughed heartily, and he danced with his two sons and said:

"The Holy City will be a beginning, and I will practice my ultimate ideal from here, so that every race, whether it is the demon race, the dark elf race, or the demon race, can live here equally!"

The young Yifeng stood solemnly and silently, listening carefully to his father's words word by word.

At that time, Yisheng was also in the prime of life, with a majestic posture and blazing eyes. He is the strongest Fire Saint Demon Master respected by everyone on the continent, and he is the leader of the Chiyan family.

What he said about the "ultimate ideal", Yi Feng has heard it thousands of times, but every time he sounds it, he still feels excited.

The young Yi Xin didn't understand much of this, he just blinked his big innocent eyes, looked up at the sky, and followed the butterflies flying by him.

"Alas......"

Thinking of this, Yi Sheng, who was in the empty illusion, suddenly sighed and looked depressed. The past is vivid, but time has passed.

In the Demon King City, blue light flickered on the stone walls of the secret chamber on the top floor.

Yi Feng, who was sitting in the center of the magic array, was naked, and the huge black wings behind his back were constantly absorbing the energy transmitted from the magic array, growing slowly, and the black shadow covered the sky above the entire secret room, and the evil aura was awe-inspiring.

Underneath the huge four wings, the rudiments of the fifth and sixth wings have slowly emerged from their backs. The newborn feathers tore through the flesh and flowed blood. The flesh buds of the wings gradually stretched out as if they were hungry for energy.

The process of feathering is accompanied by the pain of breaking muscles and bones, like breaking a cocoon into a butterfly. As the wings on his back grew, the two scarlet openings that had been torn apart expanded, and blood flowed sideways, staining a whole new feather.

Yi Feng endured the pain, clenched his teeth, and the bones in his wings "crackled", still stretching to the sides, breaking through his own limits.

It wasn't until the wings almost filled the space that the place close to the back began to take shape, and the wound no longer expanded, but instead healed quickly under the urging of the dark blood, and the blood was quickly absorbed by the pitch-black feathers, and it emitted a dark luster.

At this time, the newborn pair of wings had stretched to nearly half the length of the other two pairs of wings, which meant that Yifeng's strength had made a qualitative leap.

After experiencing the pain of Hua Yu, Yi Feng's breath gradually stabilized. He continued to concentrate his mind and look inwardly, absorbing the energy from the magic array.

This blue magic array in the secret room is the source that connects the huge magic array on the original battlefield in the outside world. And the one who was manipulating it was Ling Xi who was standing behind the magic platform at this time.

Even if he was powerful and his mana was unfathomable, after urging such a huge magic array, he couldn't help but have his lips slightly pale, his face was pale, and fine beads of sweat oozed from his forehead.

After all, every time he absorbs the power of the revenant soul from the battlefield, and then turns this power into energy for Yi Feng to absorb, it requires his extremely precise control, and how many such revenant souls there are in the vast battlefield needs to distract how much of his mind. It can be seen how difficult it is to maintain this magic array.

At this time, seeing that Yifeng's third pair of wings had finally been generated, Ling Xi also breathed a sigh of relief.

He poured the last of his mana into the magic circle. The pages of the magic book in front of him flipped and the dazzling light flashed, suddenly strong, and then dimmed and extinguished.

His whole aura also quickly fell, and he took a step back with exhaustion.

Ling Xi's eyes suddenly darkened, his footsteps flickered, and he almost didn't stand firm. He held his forehead, calmed down for a moment, and slowly sat down with his back against the magic table. In the face of strong people, he can also deal with it calmly and has always been at ease, but he rarely shows such an exhausted appearance.

"That's it, as soon as you generate new wings, the forces of darkness will guide you to continue absorbing the energy of the magic circle. I'll rest for a while and regain my mana. The magic circle will continue to operate according to the pre-arranged formation. If you can sacrifice all the Terrans and Demons as 'living sacrifices' according to the plan, you will be able to successfully transform the eighth wing. ”

He said weakly. After the will that supported the magic array receded, his limbs immediately felt soreness, and his mana was almost exhausted.

The eighth wing, after Yi Feng heard it, the corners of his cold mouth gradually flashed with a smile of expectation.

Among the Protoss, the size and number of wings determine rank and status. With each extra pair of wings, the growth of mana is not just doubled, but a world of difference.

Ordinary Protoss has to go through tens of thousands of years of accumulation before they can finally turn into feathers, ascend to the sky in one step, and look down on all beings.

Yi Feng's own dark power has the ability to devour other lives to improve himself, so he has an advantage over the Protoss.

The stronger the devoured lifeform, the more energy it gains. The magic array cast by Ling Xi also relied on this.

Still, it would take a lot of effort to evolve from the original four wings to the current six wings, or even the more outstanding eight wings.

This battlefield is the best choice.

Now that the superb combat power of the entire human world is concentrated on this battlefield, they will all be transformed into the nourishment of Yifeng's evolution of complete wings.

As soon as Ling Xi sat down on the ground, gasping softly to recover his mana, there was a sound of squirming footsteps on the stairs outside the door of the secret room.

Immediately afterwards, I heard the wooden door at the end of the corridor on the top floor being pushed open, and I came to the secret door of the secret room.

The conversation between Ling Xiaotear and Black Feather came faintly.

"Look, there's a secret door here! Boss Ling and Yifeng must be behind the secret door. Ling Xiao said with tears.

Black Feather used his perception to probe behind the secret door, and for a moment, his consciousness seemed to have fallen into a hideous and terrifying hell, and the monster that couldn't see the form was crouching there.

He immediately regained consciousness and broke out in a cold sweat. As a demon king, he didn't know what other power in this world could make him so afraid.

Ling Xiaoxian didn't notice the change in the black feather, she carefully observed and groped the wall, and suddenly, her finger swiped over the side of the secret door, and a mysterious rune lit up.

"Ah! here's the way to crack the secret door. She said in surprise, infusing her mana to explore the mysteries of the runes.

A purple light twisted and twisted, flowing along the staggered trajectory of the runes, like a key wandering in a keyhole,

But this keyhole is a labyrinth, and soon she has no clue.

"It's so complicated, Boss Ling bullies people, I can't crack it at all......"

Ling Xi closed his eyes and listened to the outside of the door, he knew that with Hei Yu's current perception, he would definitely find out the clues inside the door. This secret door can't stop him, instead of letting him break in and be embarrassed, it's better to invite him in generously.
