Huiyi finished speaking and flew towards the depths of the sea of fire.
"Huiyi, be careful!"
Zi Linling exhorted, then chased after her. She had also comprehended the Law of Fire, but her control over flames was, after all, no match for Huiyi, a natural darling of fire.
A moment later, Zi Linling was left far behind by Huiyi.
"Huiyi, wait for me!"
Zi Linling continued to pursue Huiyi while fending off the fire spirits in the sea of fire.
However, Huiyi, sensing her true form, was already too excited to think straight.
She hurriedly said, "Master, don't worry, the flames here won't harm me. You wait for me here, I'm going to merge with my true form!"
As a Fire Phoenix, Huiyi was a favorite of fire. In a short time, she had disappeared into the depths of the sea of fire.
Zi Linling sighed, shook her head helplessly, and then proceeded into the depths of the sea of fire for a while, reaching her limit.
Then, she sat down cross-legged, closed her eyes, and began to cultivate.
As time went by, Zi Linling's comprehension of the Law of Fire deepened.
The Law of Fire danced around her with enthusiastic familiarity, showing a strong sense of closeness.
She, who was originally about to be ignited, actually felt that the temperature of the flames was not so terrible anymore.
Zi Linling smiled, opened her eyes, and continued to walk towards the depths of the sea of fire.
She had adapted to the temperature of the flames here, and further cultivation would be ineffective.
Zi Linling pressed onward until she felt the sensation of being on the verge of ignition again, at which point she stopped to cultivate.
Once she had adapted to the surrounding environment again, she rose and moved forward once more.
Thus, she repeated this cycle, slowly approaching the depths of the sea of fire.
With every stretch of distance she traveled, her cultivation also grew.
In the depths of the sea of fire, Huiyi's primordial spirit gazed at the thousand-zhang phoenix that lay dormant, the excitement in her eyes clearly visible.
The phoenix's entire body was covered in scorching flames, emanating a suffocating aura.
That familiar feeling, having weathered hundreds of thousands of years of vicissitudes, impacted Huiyi's primordial spirit.
Huiyi approached the fiery phoenix step by step, slowly.
She could feel that as long as her primordial spirit merged with her true form, she could quickly return to her peak state.
Then, she would absorb the origin of fire here, break through the limitations of the Fire Phoenix bloodline, and evolve into the divine beast Vermilion Bird.
As the distance between her primordial spirit and true form constantly shortened, Huiyi became more and more nervous.
But the moment her primordial spirit touched her true form, a crimson light shot out from the true form, directly repelling her primordial spirit.
What was going on?
Huiyi was utterly bewildered.
But at this moment, a faint, intermittent memory appeared in her mind.
"Seal... Fire Origin Stone... Goddess's Blood... Kunlun..."
What was this?
Huiyi, unable to understand the meaning, sat still and entered a meditative state.
A moment later, she cautiously extended her hand again, trying to touch her dormant true form.
As expected, Huiyi's primordial spirit was repelled again.
But at the same time, another intermittent memory flooded into her mind.
This time, it was a scene.
In the scene, a woman of unparalleled beauty looked with a sad expression at a phoenix engulfed in sky-burning flames.
That woman bore a striking resemblance to Zi Linling, with only a slight difference: the woman's aura was gentle, unlike Zi Linling's cold demeanor.
Huiyi's lips trembled violently as she choked out two words: "Master!"
Indeed, that woman was Huiyi's master from a hundred thousand years ago, Feng Lixi, the predecessor of Zi Linling. Zi Linling was the result of Feng Lixi's reincarnation and partial reincarnation, which had developed independent consciousness.
As Huiyi called out, a piece of crimson stone appeared in Feng Lixi's hand. This stone was the Fire Origin Stone.
Feng Lixi threw the Fire Origin Stone towards the fiery phoenix and quickly formed hand seals.
Simultaneously, she spat out a mouthful of vital blood, spraying it onto the Fire Origin Stone.
The fiery stone landed on the fiery phoenix, and the sky-burning flames on the phoenix immediately subsided, slowly retreating into its body.
The fiery phoenix let out a sound of unwilling cry and fell into a deep slumber.
Feng Lixi stripped away the primordial spirit of the fiery phoenix and stored it in the Hall of the Goddess.
Then, she set up a great formation around the fiery phoenix.
Countless heavenly fires descended from the sky, instantly turning the area within a radius of ten thousand li around the fiery phoenix into a sea of fire.
The scene in Huiyi's mind ended here, but the fragmented words she had heard earlier became complete.
"To break the seal, awaken the Fire Stone first, with the Goddess's blood, summon Kunlun's spirit!"
Huiyi gazed at the sixteen characters that appeared in her mind and fell into deep thought.
Zi Linling moved intermittently, the Law of Fire swirling around her becoming increasingly dense and solid.
However, her meridians were filled with burning pain, and she even coughed out flames from her nose and mouth from time to time.
As Zi Linling ventured deeper, the pain of her meridians being burned grew more pronounced, until three days later, the pain reached a point she could no longer bear.
It should be noted that Zi Linling's endurance was exceptionally strong; otherwise, she would not have been able to withstand the pain of bone and marrow cleansing from the Tendon-Shaping Pill and Marrow-Washing Pill back then.
Now, the pain of her meridians being burned was so severe that even someone like Zi Linling could not endure it, which indicated the extent of the agony.
Helplessly, Zi Linling had to stop.
She knew that this burning pain in her meridians was caused by fire poison, so what she needed to do now was to clear the fire poison as quickly as possible.
Otherwise, once the fire poison fully erupted, the meridians within Zi Linling's body would be completely ignited and burned to ashes.
At that point, even if she survived, she would become a cripple.
Zi Linling sat cross-legged in her spot, her mind rapidly contemplating methods to clear the fire poison.
Suddenly, an idea struck her, and she heavily patted her head, muttering to herself, "Hey! How could I forget this!"
Fire poison was still a poison, and naturally, it could be used to temper the Myriad Poison Body.
She acted on her thoughts immediately.
Zi Linling carefully submerged her divine sense into her body, then used her divine sense to wrap the fire poison in her meridians and send it to her upper dantian.
With the "Human Emperor's Medical Canon" and "Scripture of Creation" in existence, the fire poison could not infiltrate her divine sense at all, which was the basis of her confidence in directly wrapping the fire poison with her divine sense.
After sending the fire poison to her upper dantian, Zi Linling moved her thoughts, formed hand seals with her divine sense, and sealed the fire poison, leaving only a small crack.
Through this crack, she cautiously drew out a wisp of fire poison, then, following the method for tempering the Myriad Poison Body, slowly refined this wisp of fire poison and integrated it into the skin, flesh, bones, and marrow of her body, strengthening their resilience.
