After the Ancestral Dragon and his two companions left the Immortal Execution Formation, they sped towards the location where Hongjun and Rahu were fighting. Their abandonment of Li Yi and the others outside the formation was already ungentlemanly, so they felt compelled to aid Hongjun, providing an excuse should Li Yi and his group survive.
Rahu, initially, had heard no explosions from the direction of the Immortal Execution Formation and suspected some unforeseen development. The arrival of the Ancestral Dragon and his companions, however, put him at ease. Without the Ancestral Dragon holding the Four Swords of Immortal Execution in place, it would be impossible for those three Daoists to break the formation. He might not even need to detonate the formation himself to annihilate them all.
Upon seeing the three arrive, Hongjun called for everyone to attack Rahu together. The three, having failed to uphold Hongjun's trust, immediately joined the assault on Rahu when he signaled them.
After Li Yi and his two companions broke the Immortal Execution Formation, they headed towards Rahu and Hongjun. They spotted Rahu not far away, and Yuan Shi and Tong Tian were furious.
"Hongjun, the old scoundrel, broke his promise! He said he'd hold off Rahu, but now he's let him come to harm us brothers. His heart deserves to be slain!"
Li Yi's expression also darkened. He had initially put the greater good first, intending to deal with Rahu before demanding an explanation. He hadn't expected to encounter Rahu here. He had thought that Hongjun, vying for the chance to attain Dao, would spare no effort in dealing with Rahu, but he had overestimated him.
With their anger finding no outlet, the three didn't hesitate to engage Rahu. Li Yi summoned the Xuanhuang Pagoda to protect his brothers and unleashed the Coiling Dragon Staff at Rahu. Yuan Shi and Tong Tian were equally active, brandishing the Hongmeng Heavenly Measuring Ruler and the Qiankun One-Qi Lock to attack Rahu. The four engaged in a fierce battle.
Although Rahu's outer manifestation was not weak, he lacked spirit treasures to defend himself and no treasures for offense. He was no match for the three. Li Yi noticed that Rahu was gradually faltering under his brothers' assault but was not deploying any magical treasures, and a suspicion arose.
Li Yi said to Yuan Shi and Tong Tian, "This is likely not Rahu himself. Under the combined attack of us three, Rahu hasn't even deployed a single spirit treasure. It's certainly not Rahu."
Yuan Shi and Tong Tian heard this and looked at Rahu. It was indeed as their eldest brother had said. Yuan Shi, still seething with anger, declared, "Who cares! Since he looks exactly like Rahu and is inextricably linked to Rahu, let's kill him first and then deal with Rahu!"
With that, Yuan Shi's attacks became even more ferocious. Both the Hongmeng Heavenly Measuring Ruler and the Qiankun One-Qi Lock were being used for the first time, and through this battle, they became familiar with these two innate supreme treasures. Li Yi, knowing his two younger brothers were angered and in a bad mood, didn't say much, but his Coiling Dragon Staff struck Rahu with increasing force. Though Li Yi didn't voice it, he was also displeased that his brothers had been outmaneuvered. Rahu's manifestation became a tool for their pent-up fury.
The three attacked with all their might, their spirit treasures augmenting their blows. Rahu, struck by their combined attack, had his body dispersed into wisps of black energy that vanished into the heavens and earth.
Just as Rahu's manifestation was destroyed by Li Yi and his companions, Rahu, who was fighting Hongjun and the Ancestral Dragon, suddenly spat out a mouthful of blood. Hongjun seized the opportunity, and the Pangu Banner's emitted Chaotic Sword Qi struck Rahu's chest fiercely.
Rahu glared at Hongjun and said, "I didn't expect you to invite an expert capable of destroying my outer manifestation."
Hongjun looked bewildered, unsure who Rahu was referring to. However, he could tell Rahu was not in good condition. Even without knowing who Rahu was talking about, it didn't stop him from attacking a fallen foe. Hongjun, along with the Ancestral Dragon and his companions, launched a furious assault on Rahu, showering him with divine abilities and spirit treasures.
With his outer manifestation destroyed by Li Yi and his group, Rahu's origins were injured. He knew that if he didn't fight seriously today, he might truly perish at their hands. He raised the God-Slaying Spear to block Hongjun's attacks and chanted a spell, shouting, "With my true body, I forge my divine soul. Let the demonic body descend and protect my true spirit!"
As Rahu finished, the surrounding void shattered like glass, and streams of chaotic energy flowed around him. Simultaneously, Rahu's body emitted waves of black energy that merged with the chaotic energy in the void, coalescing behind him to form a terrifying black silhouette. This figure exuded an aura incompatible with this world. Tribulation clouds suddenly gathered in the sky, as if something evil, anathema to this world, had appeared.
Hongjun and the other three, enveloped by the black figure's aura, felt their strength drain away. Alarmed, they hastily retreated from the area, and the sense of powerlessness dissipated. Hongjun retreated to a distance and, upon looking closely, exclaimed in shock, "Chaotic Demon Body? How is this possible? Wasn't your demon body destroyed by Pangu?"
Rahu roared with laughter, "Hongjun, you didn't expect this, did you! When my divine soul escaped from Pangu's axe in the past, I managed to take a drop of my demon body's essence blood. After years of meticulous nurturing, it has now evolved into my demon body!"
"Hahaha, hahaha!"
"You're just waiting to die!"
"Hahaha, hahaha!"
Hongjun knew that with Rahu's Chaotic Demon Body, he was no longer his match. However, the opportunity to attain Dao was before him, and he was unwilling to retreat like this. Thus, Hongjun gathered his courage and attacked Rahu with the Pangu Banner. It struck Rahu's Chaotic Demon Body with minimal effect.
Rahu laughed heartily, "Hongjun, you are also a Chaotic Demon God, aren't you aware that my Chaotic Demon Body can only be broken by Chaotic Spirit Treasures? If not for your Pangu Banner being forged from a fragment of Pangu's Axe, how could you have injured me?"
Hearing Rahu's words, the Ancestral Dragon and his two companions immediately distanced themselves from Hongjun, their eyes warily fixed on him. They never imagined that both Hongjun and Rahu were among the three thousand Chaotic Demon Gods. The three, being among the first beings after the creation of heaven and earth, understood what it meant to be a Chaotic Demon God.
Seeing this, Hongjun quickly said, "Fellow Daoists, do not listen to Rahu's slander. I am a being born after the creation of the Primordial World."
As Hongjun was explaining, the tribulation clouds above Rahu's demon body had fully formed, and streaks of lightning struck his Chaotic Demon Body. Instead of being harmed, Rahu's Chaotic Demon Body absorbed the power of the lightning, growing even stronger. Rahu's Chaotic Demon Body, born from chaos, could only be injured by Chaotic Divine Thunder, Chaotic Spirit Treasures, the Primordial Clear Light, and the Primordial Yellow-Black Qi. However, the Heavenly Dao of the Primordial World was far from capable of summoning Chaotic Divine Thunder. Chaotic Divine Thunder could only be summoned by the cosmic consciousness outside the Primordial World.
Rahu, seeing that even the Heavenly Dao could not harm him, and hearing Hongjun denying his identity as a Chaotic Demon God to the Ancestral Dragon and his companions, could not help but laugh heartily, "I never expected you to deny your identity as a Chaotic Demon God and willingly associate with these lowly insects. You truly are going backward in your old age."
Hongjun, listening to Rahu's taunts, felt a pang of unease. As a Chaotic Demon God, he possessed his own pride, but he was currently at a disadvantage. If the four became divided, they might all perish here today. Seeing the suspicion in the eyes of the Ancestral Dragon and his companions, and with Rahu fanning the flames, Hongjun knew he could no longer conceal the truth. He admitted, "Fellow Daoists, do not listen to his nonsense. Although I was a Chaotic Demon God, I have long since reincarnated and cultivated anew, and have no further connection to the Chaotic Demon Gods. Let us now stand united against our enemy!"
While the three were half-believing Hongjun, the current situation allowed them no room for doubt. If they couldn't escape, nothing else would matter! The four had long since abandoned the idea of defeating Rahu; escaping at this point would be incredibly fortunate.
Rahu, seeing the four united once more, knew his plan to sow discord had failed. However, he was not worried. Although his Chaotic Demon Body placed a heavy burden on him, it was invincible within the Primordial World. He had not sensed the aura of any Chaotic Spirit Treasures in the Primordial World. The only time he had sensed the aura of the Chaotic Pearl, he had been unable to find it, so he must have been mistaken. The Primordial Clear Light and the Primordial Yellow-Black Qi had long since dissipated into the world after Pangu's creation. Chaotic Divine Thunder was even less likely; the Primordial World currently could not produce it.
