"Hold on..." Chen Feng gritted his teeth and rushed into the gray fog, speeding towards the center he remembered. Along the way, the sealing chains vibrated violently, and black spheres bulged out from time to time, as if more Devouring Beasts were about to break free of the seal.

The deeper he went, the denser the chaotic energy became. The chaotic vortex within Chen Feng's body spun wildly, absorbing this shared power, allowing him to temporarily forget his fatigue.

Finally, he arrived at the center of the Chaos Sea. Here, a huge whirlpool slowly rotated, and at the center of the whirlpool floated a peculiar stone—shaped like two connected hearts, half golden and half silver, radiating a soft yet resilient light.

"The Twin Heart Stone!" Chen Feng was overjoyed and was about to take it when countless transparent tentacles suddenly emerged from the vortex and wrapped around him. These were the seal's own defensive mechanism, which would attack anything that tried to approach.

The guardian wing pattern on Chen Feng's left hand suddenly lit up, and the tentacles hesitated. He seized the opportunity and rushed towards the Twin Heart Stone with all his might.

Just as his fingertips were about to touch the stone, the entire Chaos Sea suddenly trembled violently. From afar came Yunyi's heart-wrenching screams, accompanied by the satisfied howls of the Devouring Beast.

"Cloud Wings!" Chen Feng was shocked and almost got swept away by the tentacles. He forced himself to calm down and grabbed the Twin Heart Stone.

Strangely, the moment he got his hands on the Twin Hearts Stone, the chaotic energy within his body perfectly merged with the golden part of the stone, while the silver part trembled slightly, as if calling out to something.

"I see..." Chen Feng suddenly realized, "It must be used by two people simultaneously, one holding the gold heart and the other holding the silver heart!"

He immediately turned and rushed outside, praying that Yunyi was still alive. The howls of the Devouring Beast grew closer, clearly indicating that it had overcome the obstacles outside and was now chasing after him.

When Chen Feng emerged from the gray mist, the scene before him tore at his heart—Yun Yi lay in a pool of blood, one side of Tian Yu Shen Yi was broken, and her breath was as faint as a candle flickering in the wind. Above her, the Devouring Beast stood with its gaping maw, ready to feast.

"Stop!" Chen Feng roared, pressing the golden part of the Twin Hearts Stone to his chest while forcefully throwing the silver part towards Yunyi. "Catch it!"

With his last ounce of strength, Yunyi raised his hand and caught the Silver Heart Stone. In an instant, golden and silver light shot into the sky, forcing the Devouring Beast back. The two stones glowed simultaneously, echoing each other and forming a perfect energy cycle.

Chen Feng felt an endless surge of power flowing into his body, and his realm instantly broke through to the demigod realm! He looked at Yun Yi and found that her injuries were also healing rapidly, and her broken wings were growing back, even more magnificent than before.

"This is... the power of the progenitor?" Yunyi looked at his completely renewed wings in disbelief.

The Devouring Beast was stung by the light, and black liquid flowed from all six of its eyes simultaneously. It roared angrily and charged at the two of them recklessly.

"Together!" Chen Feng extended his right hand.

Yunyi understood and clasped his left hand in his. Simultaneously, they both raised the Heart Stone in their other hand: "Seal - Reset!"

The light of gold and silver intertwined, transforming into countless chains that coiled around the Devouring Beast. The monster struggled frantically, but could not break free from these chains imbued with the power of the Primordial Ones. In the end, it was forcibly dragged back into the gray mist of the Chaotic Sea, letting out a resentful howl before vanishing.

The gray fog thickened again, and the tremors gradually subsided. But Chen Feng knew that this was only a temporary solution for one of the larvae; the entire seal remained extremely fragile.

"We need more power..." He looked into the distance, towards the continent of myriad races, "We must unite all races to strengthen the seal."

Yunyi nodded, his Heavenly Feather Divine Wings fluttering gently: "I will persuade the Eagle People."

They smiled at each other; after sharing life and death, a bond that transcended race had quietly taken root. But they both knew that the real challenge had only just begun...
