In the Great Demon Heaven world, above Mount Sumeru, lies Rahu’s Grand Dao Treasury Realm, the source and origin of the demon race.
Qinglong entered, the mist was dense and obscure, with no one coming or going. Black qi churned, with no sun or moon, no distinction between heaven and earth.
The spirits of all demons hid in the mist, and countless strange cries, roars, and calls came from all directions.
Qinglong frowned, glanced around, and with a flick of his sleeve, a clear breeze swept across the vast sky. Countless demons and monsters retreated in fear, spontaneously clearing a path.
He took a step forward, and when his foot landed again, he had already reached the end of the path.
Rahu looked up at the newcomer, a strange smile on his face, "What, has Ancestral Dragon thought it through?"
Qinglong nodded gravely, "Indeed."
Rahu's face immediately broke into a smile. Even he was overjoyed at the prospect of achieving this.
"Good! When will that old fellow Ancestral Dragon come to see me?"
Qinglong raised an eyebrow, "Eldest Brother will not come to see you."
Rahu's smile froze, turning grim, "Qinglong, do not toy with this Ancestor."
Qinglong extended his palm, and a golden dragon scale radiated immense dragon might, causing all surrounding demonic energy to dissipate.
"With this as a pact, do you believe me?"
Seeing this, Rahu’s smile returned, "With Ancestral Dragon's true scale, it naturally cannot be false. However, if he does not come to see me, how shall we plan?"
Qinglong glanced at him and waved the dragon scale, "With the true scale's divine power, even Phoenix Ancestor and Hongjun will not be able to detect it. You and Eldest Brother can discuss it slowly."
Rahu said with a half-smile, "Why is Brother Qinglong in a bad mood today?"
"You know why I have come."
"For that little snake on the mountain?"
"I have come to bring him back."
"Impossible. He carries the destiny of Pangu's Buzhou Mountain. He is the only Pangu destiny in this world that I can grasp."
"You will not release him?" Qinglong's brow furrowed.
Rahu smiled faintly, "I will. Since a pact has been made, I must release him. However, I have another condition."
"What condition?"
"Take my Immortal Slaying Sword with you and place it in the eye of the East Sea."
"Why?" Qinglong's eyes became serious.
A terrifying madness appeared in Rahu's eyes: "In the Primordial World, the four elements, the four directions, I shall use the four swords to suppress heaven and earth, and refine all living beings."
Qinglong's expression turned grim, "I cannot do that."
"Don't rush," Rahu beckoned, and myriad sword qi of purple light surged forth, forming a single sword engraved with his name, "Immortal Slaying."
"Take it back and ask Ancestral Dragon. If he is unwilling, you can return it to me."
Qinglong pondered for a long time, looked at the Immortal Slaying Sword, and put it into his sleeve.
Rahu smiled with satisfaction, "The Dragon race will surely walk alongside the Demon race in this world."
Qinglong's expression was indifferent, "Then I will take the person. Demon Ancestor, it is best not to disturb my Dragon race members again."
As he finished speaking, Qinglong stepped out of the Great Demon Heaven world, not wanting to stay a moment longer.
In the endless demonic energy, Rahu let out a low, elegant laugh that revealed terrifying cruelty. No matter how rational he appeared on the surface, he was inherently a demon, the ancestor of all demons. In terms of madness, who could compare to him?
Qinglong naturally knew this. He had always disagreed with Ancestral Dragon's actions, but among the five great ancestors, he was the only one who opposed it, and even Bailong had no choice but to agree to this decision.
To associate with demons was extremely dangerous. But if they did not associate with demons, the Dragon race would be trapped like caged dragons with no hope of survival.
The Qilin race had already allied with the Phoenix race. The combined strength of the two races already surpassed the Dragon race by a third. Moreover, there were already many powerful beings in the world who were dissatisfied with the Dragon race, and they would certainly not show mercy to the Dragon race in the future.
If the Dragon race won the struggle between the Dragon, Phoenix, and Qilin, then the world would enter an era of sole supremacy. Where would they have a place to reside?
But if the Dragon race lost, and the Phoenix and Qilin divided the world, the difference between sole supremacy in the Primordial World and division of the world was too great.
However, they did not expect the Dragon race to ally with demons. How many people in the world would dare to do such a thing? Yet, the Dragon race had done it in secret.
The world had long undergone a great change without anyone knowing, and it was only a matter of time before the prelude was revealed.
On Mount Sumeru, beside the Eight Treasures Pool, Qingling was still refining the primal energy of heaven and earth with all his might. The Grand Dao Treasury Realm in his Dantian sea was devouring it crazily.
Every powerful being was a spirit energy tank, absorbing immeasurable amounts of spiritual energy from heaven and earth.
The spiritual energy absorbed by a powerful being to cultivate and achieve enlightenment was more than what countless living beings required in their entire lives.
Therefore, when the primal energy of heaven and earth gradually decreased in the later ages of the Primordial World, the Heavenly Dao would set its sights on powerful beings.
If a powerful being died, the spiritual energy returned to heaven and earth would be enough for tens of thousands of living beings to cultivate for thousands of years.
If an ultimate powerful being perished, it could even return enough spiritual energy to sustain the cultivation of hundreds of millions of living beings in a large region for a long time.
As for ancient beings like Qingling, if they became ultimate powerful beings and perished, the spiritual energy returned to heaven and earth would be even greater.
If beings like Ancestral Dragon and the Qilin Kings died, the returned spiritual energy could even initiate the next era.
However, the powerful beings of this era had not realized this, or rather, they had never thought that they would perish under the Heavenly Dao.
Qingling was wholeheartedly refining the tidal surge of spiritual energy from heaven and earth when a figure suddenly appeared beside him.
"You're doing well, kid."
Qingling was startled, his focus wavered for a moment, and he asked directly, "Lord God, why are you here?"
Qinglong glanced at him and said slowly, "If I don't come again, who knows what trouble you'll stir up for me."
Qingling's face turned embarrassed, and he quickly changed the subject, "Lord God, I am still breaking through my realm and cannot be distracted."
Qinglong frowned, "Do you expect me to carry you back?"
Qingling's heart trembled, and he quickly said, "Lord God, I am still imprisoned here by the Demon Ancestor."
"Since I am here, I am here to take you back," Qinglong said expressionlessly, "If you don't want to leave, you can stay here."
Qingling hurriedly stood up, neglecting the refinement of his Dantian's primal energy, "I'll go, I'll go!"
Seeing his demeanor, Qinglong said, "Forget it, come in first."
With that, he pointed his finger, and a projection of a world appeared behind him, filled with tall and sturdy trees. Each ancient tree was like a divine dragon, tens of thousands of them, arranged across the land.
And in the sky, countless sword qi hung inverted, with endless green peaks pointing towards the heavens.
Qingling was thrown into this world.
Qinglong retracted his Dao realm and flew away in an instant.
However, he did not expect that due to the牵引之力 (pulling force) caused by Qingling's breakthrough, while Qinglong flew, he was still gathering the surrounding primal energy of heaven and earth.
Therefore, as Qinglong flew, a long trail of elemental tides followed his dragon tail, presenting a five-colored hue, like a rainbow spanning east and west.
The dragon soared through the nine heavens, riding the wind and clouds, accompanied by thunder and rain. Clouds gathered for ten thousand miles, a single gust of wind, lightning flashed across the nine heavens, rain fell upon the great wilderness, and a rainbow bridge spanned the universe. Leaving behind the old days, he finally returned from the west.
