After a moment, Dong Yan continued, "After my father's squad obtained those things, he killed the other companions.
Then my father fled to the Western Desolate Region to cultivate in seclusion. After that, he relied on those things to start from scratch, founded the Fire Spirit Sect, and developed it to this day."
After hearing these words, Lin Feng also gave a slight nod. As for what the other had said, he felt the credibility was quite high.
After all, aside from that Light and Shadow Space left by the Dou Di expert, he really couldn't think of any other place where such a secret art could be obtained.
Thinking of this, Lin Feng immediately spoke, "Then aside from the technique to refine the Emperor Spirit Flame, what about the other items?"
"My father brought out most of the items, but over these several hundred years, for various reasons, they were all consumed. Only a white key of unknown use remains, hidden in the deepest part of my storage ring."
Seeing the question, Dong Yan answered honestly without hiding anything.
After all, the pain of Fallen Heart Flame scorching the soul was not something he ever wanted to experience again.
"Fine, I'll believe you for now. But if I find anything that doesn't match what you said, you can wait to enjoy the pain of your soul being burned."
With that, Lin Feng made a beckoning gesture, once again sealing Dong Yan's soul into the jade bottle and tossing it back into his storage ring.
After finishing these tasks, Lin Feng resumed exploring the parts of the storage ring he hadn't yet examined.
After all, the estate of an Eight–Star Dou Zun peak expert was, to him now, a massive trove of resources.
In an instant, that vast white space once again appeared before Lin Feng's eyes. Gazing at the rows of wooden shelves, he ignored the surrounding items with his soul sense and went straight ahead.
Based on what Dong Yan had said earlier, combined with his own rough sweep of this space before, Lin Feng soon arrived in front of the last wooden shelf in the storage ring.
His gaze swept over the items on it, and finally on the very top row he discovered a finely crafted jade box of excellent blue-green quality.
Immediately, Lin Feng guided his soul sense to take it out. Then he opened his eyes and looked at the jade box now in his hand.
"Ka~"
As Lin Feng gently lifted the lid, a white key quietly resting inside the jade box entered his sight.
This key, no one knew what kind of metal it was made of, but its entire body was pure white and flawless.
Even the pure white mutton-fat jade could not match the sheer purity of this key's whiteness. On it were carved lines of mysterious patterns that were impossible to fathom.
However, judging from the unnaturally broken lines along the edge of the key, this strange key should not be the only one of its kind.
It was just that when Dong Yan's father had explored that Light and Shadow Space left by the Dou Di expert, he had only chanced upon this single piece. And yet, though no one knew how many countless years this key had existed, it still emitted a faint white glow.
Under the illumination of that white glow, Lin Feng felt extremely comfortable, an incomparable sense of peace washing over him.
After a moment of silence, Lin Feng stretched out his hand and picked it up, playing with it lightly. And at the instant he lifted that icy-cold key, a surge of extremely rich life force immediately spread out from within the key, rapidly entering his body.
At the same time, the white flame of the Yin-Yang Twin Flame within him suddenly became violent. Its appearance was as if it had found something identical to its own origin.
"How can this key contain such a rich force of life? And it even seems to have some connection to the white flame of my Yin-Yang Twin Flame. Could it be because of this life force?"
Gazing at the key in his hand, Lin Feng murmured inwardly.
At this moment, he finally began to understand. Why, under that white radiance, he had felt such incomparable peace.
It must be that within the glow released by this key, there also existed the same life force as the white flame of the Yin-Yang Twin Flame. That was why he had that feeling.
"This kind of dense life force—if a cultivator whose lifespan was nearly exhausted were to wear this key, extending life by decades, even a hundred years, probably wouldn't be any problem at all."
Sensing the life energy flowing from the key into him, Lin Feng muttered in surprise.
He truly could not imagine who could have forged such a key. After such a long span of time, it still possessed such miraculous effects.
"Could it be that this eerie key was crafted by the master of that Light and Shadow Space?"
Looking at the key in his hand that gave off a faint glow, Lin Feng speculated.
After all, aside from the master of that space, he could think of no one who would create such a strange key and then leave it there.
"Bang!"
Just then, the white flame of the Yin-Yang Twin Flame within his body, seeing such a feast before it, suddenly surged forth.
A mass of white flame rolled uncontrollably from his palm, rushing straight toward the white metal key. However, when the white flame touched the key, the white glow on the key abruptly flared bright.
A suction force suddenly burst forth from the key. Under this powerful pull, the power within the white flame was instead seized by the key.
That originally ferocious white flame now became like a fish on a chopping block, utterly without resistance. And that white flame, suppressed and unable to move, seemed to remember at this moment that it still had a master. It quickly sent a message, pleading to Lin Feng for help.
"Damn!"
Seeing this, Lin Feng hastily cut off his connection to the circle of white flame near the key.
Right after, he quickly withdrew the rest of the white flame back into his body to avoid further mishaps. The white flame he abandoned was instantly devoured completely by the key. Afterward, the white light on the key became even more intense.
"This key is really formidable. The Yin-Yang Twin Flame touched it once and was completely suppressed, without the slightest power to fight back."
Sensing the white flame inside him trembling, Lin Feng clicked his tongue.
Although the Yin-Yang Twin Flame was only ranked twenty-first on the Heavenly Flame Ranking, it was still a true Heavenly Flame. And it had existed for quite a long time.
Otherwise it could not have given him, an Eight-Star Dou Zong, such a notable boost in strength. Yet even such a Heavenly Flame had no ability to resist when facing this key.
"Forget it, I'll study this thing later."
After playing with it for quite a while and finding nothing more, Lin Feng let out a quiet sigh. He then placed the key back into the jade box and stored it in his own storage ring. After that, he once again began exploring Dong Yan's ring.
