Longevity Martial Arts: Grinding Experience in the Chaotic World

Yan Ruyu smiled faintly, her eyes shimmering with a unique radiance, "Young Master Gu, you have done a great favor for our Demon Clan. Tonight, I wish to personally express my gratitude to you."

Gu Sheng stepped aside to let Yan Ruyu into the room. The two sat opposite each other. Gazing at Gu Sheng, Yan Ruyu spoke affectionately, "Young Master Gu, it has been over a year since our last meeting. Over this past year, I often thought of you, of the days we fought side by side…"

Listening to Yan Ruyu's earnest words, a warm current surged through Gu Sheng's heart. As he looked into her deeply affectionate eyes, he felt a flutter within. He knew that he harbored a unique feeling toward this enchanting and powerful woman.

Yan Ruyu gently grasped Gu Sheng's hand, her voice soft, "Young Master Gu, you have done so much for our Demon Clan—tonight, I want to offer you a special reward. If you're willing, I will do my best to satisfy any wish you have."

Feeling the warmth of Yan Ruyu's palm, Gu Sheng's heart stirred slightly. He took a deep breath while looking into her expectant eyes and said, "Saint Master Yan, I am deeply grateful for your kindness. If I must speak of a wish, it would be for the Demon Clan to flourish and enjoy eternal peace."

Yan Ruyu's eyes revealed a flicker of emotion upon hearing this. She understood that Gu Sheng was a man of great responsibility, harboring the welfare of the entire Demon Clan in his heart. Gripping Gu Sheng's hand tightly, she said earnestly, "Young Master Gu, your wish is also mine. For the sake of the Demon Clan, let us strive together."

The two exchanged a knowing smile, and the atmosphere gradually grew warmer. Yan Ruyu leaned lightly against Gu Sheng's shoulder, her voice soft, "Young Master Gu, actually, I have one more request that I hope you can help me with."

"Saint Master Yan, please speak. If it's within my power, I will not refuse," Gu Sheng replied firmly.

Yan Ruyu lifted her head and gazed into Gu Sheng's eyes. "I hope you can use your Ancient Sacred Body to nurture the Devil Emperor's Heart. This heart is vital to the Demon Clan, but it has been weakening over the years. It needs powerful life force to rejuvenate. I believe your physique and cultivation will be able to help."

Gu Sheng was momentarily stunned by her words and hesitated. Yet under Yan Ruyu's gentle persuasion, he eventually nodded, "Since Saint Master Yan has such trust in me, I shall try."

Yan Ruyu looked at Gu Sheng with gratitude, "Thank you, Young Master Gu."

They moved to the secret chamber, where a glowing heart floated midair. This was the Devil Emperor's Heart, exuding a strong aura with an imperial pressure in each rhythmic motion.

Gu Sheng took a deep breath, extending his palm to gently touch the Devil Emperor's Heart. He felt an immense life force streaming into his body, merging with his own life force. The sensation was peculiar, as though he established a mystical connection to the Devil Emperor's Heart.

Over time, Gu Sheng noticed his life force gradually depleting, yet he kept going. It felt as if Yan Ruyu had enchanted him in some way.

Yan Ruyu watched Gu Sheng with tension, fearing he might face unexpected complications. When she noticed his complexion turning increasingly pale, her heart wrenched with concern, "Young Master Gu, are you alright?"

Gu Sheng faintly smiled, "I'm fine, just a bit tired."

Yan Ruyu regarded Gu Sheng with deep gratitude and said, "Thank you, Young Master Gu. You've sacrificed so much for the Demon Clan."

As time passed, Gu Sheng felt his life force fully synchronized with the Devil Emperor's Heart. Slowly retracting his hand, he exhaled deeply, "It's done, Saint Master Yan. I've given it my best effort."

Yan Ruyu looked at the Devil Emperor's Heart with excitement. She sensed its aura had strengthened significantly, "Thank you, Young Master Gu. You've done a great service for our Demon Clan."

Gu Sheng offered a faint smile, "It was my duty to help."

The two shared a knowing smile, as if everything was understood without words. They knew that this night would forever be etched in their hearts.

Just then, the Devil Emperor's Heart emitted an intense radiance. A surge of powerful energy rippled through the entire chamber, seemingly ready to consume everything.

"Boom!"

Gu Sheng and Yan Ruyu were both taken aback by the abrupt force. They gazed at the Devil Emperor's Heart, awe and astonishment filling their eyes.

"What's happening?" Gu Sheng asked in disbelief.

Yan Ruyu was equally astonished, "I don't know; this has never happened before."

They focused on the Devil Emperor's Heart intently, watching as its light grew ever brighter, threatening to pierce the heavens. The sheer energy made their hearts pound, yet it also stirred a deep sense of thrill and anticipation.

Finally, the blazing light of the Devil Emperor's Heart began to subside. As it returned to calm, both Gu Sheng and Yan Ruyu exhaled a sigh of relief.

"It seems the Devil Emperor's Heart has received ample nourishment," Yan Ruyu remarked, her tone filled with awe. "Young Master Gu, you've brought hope to our Demon Clan."

Under the night sky, Yan Ruyu and Gu Sheng continued their conversation.

"Young Master Gu, since your physique is able to resonate with the Devil Emperor's Heart, I have another favor to ask of you," Yan Ruyu said, her voice bearing a trace of plea and anticipation.

Gu Sheng furrowed his brow slightly, "Saint Master Yan, please speak."

"I hope you can place the Devil Emperor's Heart within your Dantian sea bottom realm to nurture it for a period," Yan Ruyu's request was spoken with careful thought.

Gu Sheng was taken aback and immediately shook his head, "Saint Master Yan, I cannot agree to this. The Devil Emperor's Heart is a treasure of the Demon Clan. If something were to happen to it while inside me, how could I possibly bear such responsibility?"

"Young Master Gu, I trust you. Moreover, your unique physique makes you capable of properly nurturing the heart. I truly believe in you," Yan Ruyu's tone was unwavering.

Gu Sheng still shook his head, "No, this matter is far too risky. I cannot agree."

Seeing Gu Sheng's firm refusal, Yan Ruyu grew slightly anxious, "Young Master Gu, I beg you. The Devil Emperor's Heart is of utmost importance to the Demon Clan. Only your unique constitution can bring it back to life. I am willing to pay any price to gain your help."

Looking into Yan Ruyu's pleading eyes, Gu Sheng felt a wave of indecision. He understood the heart's profound importance but feared that introducing such a "foreign entity" into his body could lead to disastrous consequences.

Under Yan Ruyu's endless persuasion, Gu Sheng finally relented, "Alright, I'll give it a try—but only for three months."

"Thank you, Young Master Gu," Yan Ruyu said with heartfelt gratitude.

Gu Sheng took a deep breath and began channeling his energy, preparing to place the Devil Emperor's Heart into his Dantian sea bottom realm.

"Hoo—" Gu Sheng exhaled, his gaze fixed firmly upon the Devil Emperor's Heart in his palm. This was no trivial task, yet he knew he must rise to the occasion—for the Demon Clan, and for himself.

He could sense the energy surging within his Dantian, like a golden ocean waiting for its new ruler to descend.

"Sss—" A faint sound echoed as Gu Sheng pierced open the bottom of his Dantian. The golden Dantian bared a deep chasm, with surging waves of radiant energy pouring forth—a sight magnificent and awe-inspiring.

Gu Sheng carefully placed the enormous Devil Emperor's Heart into this enigmatic realm. The process was arduous; he needed to ensure the heart's stable placement without causing adverse reactions.

Yet, just as the heart was about to fully merge into the Dantian, a sudden phenomenon occurred.

"Boom—" A thunderous sound erupted as the Devil Emperor's Heart unleashed an overwhelming surge of energy. This force, like a tempest of chaos, engulfed the entirety of the sea-bottom realm. Golden waves rose to towering heights, as if trembling beneath the vibrations of the cosmos.

Gu Sheng was utterly shaken. He felt a tremendous divine presence emanating from the Devil Emperor's Heart, coalescing into a grand and imperious figure. It was the manifestation of the Demon Emperor's Divine Sense, who seemed to awaken from a long slumber, intent on claiming sovereignty over Gu Sheng's body.

"Who are you to dare place this emperor's heart into your body without permission?!" The Demon Emperor's Divine Sense roared, his voice thunderous and spine-chilling.

Gu Sheng inwardly cursed his misfortune. If the Demon Emperor's Heart were allowed to fully dominate, his body would risk becoming entirely subjugated. He had to find a way to suppress the immense Divine Sense or face dire consequences.
