Chapter 1646 Completed Chaotic Heart "That human! He's achieved fire immunity!" Feng Yao exclaimed, her expression filled with astonishment. "I didn't know humans could do that!" She had always believed that only beasts with unique bloodlines, like phoenixes, were capable of acquiring such immunity. The fact that a human had done it defied her expectations and understanding. Even in the Nine Heavens, achieving fire immunity was an exceptionally rare accomplishment. Those who managed it typically relied on special techniques, priceless treasures, and years of dedicated cultivation to reach that level. There were also those born with unique physiques that granted them fire immunity naturally, but that was a different story since they hadn't earned it through effort but were simply born with the gift. The fact that Yuan had attained this without the aid of a technique made his accomplishment all the more extraordinary. However… "No… this isn't something as simple as fire immunity!" Feng Liqiu's eyes widened as she came to this realization. [Fire Immunity] [Rank: Divine] [Mastery: Level 1] [Description: Grants the user immunity to most fire] 'What? It's fusing with my Fire Immunity?' Yuan raised an eyebrow at this notification. 'Is this similar to how my two physiques fused with each other?' Unlike fusing two physiques together, the progress this time was much quicker. "He's absorbing the flames!" Feng Yao exclaimed when she noticed this. "Fire Immunity only makes one impervious to most fire, but it doesn't have the ability to absorb flames!" Feng Liqiu narrowed her eyes and spoke, her voice calm but filled with passion. "Fire Immunity may be the end of the journey for most, but for us phoenixes, that is just the beginning." "Above Fire Immunity lies True Fire Immunity, where one becomes truly immune to all flames," Feng Liqiu continued, "And beyond that is the realm of Fire Harmony. Once one reaches Fire Harmony, not only will they be immune to fire, but they'll also be able to absorb it, transforming flames into their own power—the apex of fire control." "Are you telling me that a human has managed to achieve Fire Harmony when even I haven't been able to do so?!" Feng Yao exclaimed, her voice filled with disbelief and frustration. The idea that a mere human could reach a level of mastery that had eluded her was almost inconceivable. Feng Liqiu shook her head and said, "No, that can't be possible. He's just achieved Fire Immunity, so it doesn't make sense for him to achieve Fire Harmony so quickly. There must be something else going on inside that weird body of his." Suddenly, Yuan stood up and jumped even deeper into the Nine Levels of Hell, reaching the fourth level. The fourth level's flames were as powerful as the Phoenix's Wrath, a force Yuan couldn't withstand for more than a few seconds before. However, after achieving Fire Immunity, the once unbearable flames became barely endurable. The progress of his physique, which had stalled at 50 percent before Yuan entered the fourth level, began to rise once more. As for his Chaotic Heart, it was already on the verge of completion. "This is something different… It's similar to Fire Harmony, but it's not the same…" Feng Liqiu mused to herself as she spent more time watching Yuan. Several hours later, Yuan completed his Chaotic Heart. Ding! [Yuan] [Cultivation(Dantian): First Level Spirit Sovereign] [Cultivation(Chaotic Heart): N/A] Yuan wasn't surprised to see a second cultivation because Tian Yi also achieved the same thing after returning to the Divine Heavens and cultivating his Dantian. 𝒇𝒓𝒆𝒆𝙬𝒆𝒃𝓷𝒐𝓿𝙚𝙡.𝒄𝓸𝒎 <...> Yuan's second cultivation soared rapidly, experiencing breakthroughs every few minutes. In just a few short hours, Yuan's second cultivation reached Early Chaotic Master, akin to a 9th-level Spirit Enlightenment in human cultivation, surpassing his original cultivation. "What am I seeing right now…? I can sense two distinct energies coming from him! Is this what happens when a human forms a Chaotic Heart? I have never seen or heard of anything like this before!" Feng Yao exclaimed. Feng Liqiu narrowed her eyes at Yuan and said, "This isn't my first time seeing a human with a fully formed Chaotic Heart. Do you recall the human who made a mess in our territory several million years ago? However, he didn't have the other energy at that time, so this is also my first time seeing someone with both at once. I wonder how it affects him." "I have heard about him, but that happened before I was born." Feng Yao nodded. "Now that he's formed his Chaotic Heart, he should be leaving soon." However, Feng Yao would soon realize that Yuan had no intention of leaving so soon. He may have formed his Chaotic Heart, but he still had something else to complete. 'Chaotic Essence is essentially the same as spiritual energy, but it's more chaotic, giving it far greater destructive power,' Yuan thought, recalling Tian Yi's experience. 'Unfortunately, it can't be used with human techniques. However, I can fuse it with my spiritual energy to enhance my techniques and make them more powerful. Or, I can directly enhance my body with it.' When the fusing progress halted at 70 percent, Yuan looked to the fifth level. After a moment of stillness, his body suddenly surged with Chaotic Essence. Once he'd strengthened his entire body with Chaotic Essence, Yuan jumped straight to the fifth level, where the flames were bright green and five times more powerful than the fourth level.
