The silver-colored heavenly flame possessed an extremely strong spiritual attribute, which was different from ordinary flames. Not only did it exude an extremely intense heat, but it also radiated powerful spiritual energy, with the ability to burn and obliterate spiritual power.
Because of this, it could develop intelligence comparable to that of sentient beings, despite being a natural treasure.
Due to being in the demi-plane of the undead and absorbing soul flames from undead creatures that only knew killing, devouring, and cruelty, the intelligence it developed was extremely violent. It even sought to turn all sentient creatures in the outside world into its obedient slaves.
Last time, Huo Yuhao set a trap, using the Buddha's Fury Lotus—formed from two different types of heavenly fire—to blow up the cave where it resided. However, even that powerful energy reaction wasn't enough to completely destroy its intelligence, leaving behind some remnants.
In order to recuperate, this remnant consciousness concealed all its fluctuations, not daring to reveal the slightest trace, fearing that Huo Yuhao would notice and wipe it out completely.
In the end, patience paid off. Now, it had finally found a perfect opportunity to possess Huo Yuhao.
As long as it could take over the body of this talented young human, a bright future awaited it, where it could turn all the sentient beings in the world into its soul slaves!
"Hehehe, I've hidden myself for so long, not even daring to absorb the soul flames of the undead creatures outside, all for this moment. Now, cooperate with my possession and merge with me!"
Hearing the sinister laughter of the silver flame, Huo Yuhao's previously panicked expression suddenly turned playful. Meanwhile, in his spiritual sea, the old foxes Elder Yao and Elder Yi also chuckled.
Reaching out with his right hand, a flash of light came from Huo Yuhao's storage soul tool, and an ancient, dark carving knife appeared in his palm.
The Soul-Devouring Blade!
"Carving knife that harbors dark powers, show your true strength before me! As your master, in the name of Magical Boy Huo Yuhao, I command you—seal release!"
A brilliant gleam flashed in Huo Yuhao's eyes, and a complex divine array was carved out by Elder Yi from the spiritual sea, landing on the Soul-Devouring Blade. This was a magic specifically designed to undo all seals, a power originating from Elder Yi's original continent.
Though they were still inside the cave, sudden gusts of wind began to blow. The wind howled through the surrounding rocks, making a wailing noise reminiscent of ghostly cries.
A dark and eerie soul wave emanated from the Soul-Devouring Blade, transforming into a black thread that raced up Huo Yuhao's right arm toward his forehead. Simultaneously, a sinister voice echoed in Huo Yuhao's mind.
"Hehehe, who would have thought that after being sealed for so many years, this old man's remnant soul would have a chance to return to the world! Young boy, bear with it for a moment, I'm coming in!"
In the spiritual sea, Brother Tianmeng sneered disdainfully, "What kind of second-rate fool dares speak the same way as the great and mighty me?"
Without a doubt, this sinister spiritual will belonged to an evil Soul Master, a Title Douluo who had once wreaked havoc across the Douluo Continent and also dabbled as a Rank Nine Soul Engineer.
Like Huo Yuhao, he too was a spiritual-type Soul Master and had achieved great mastery in spiritual power. Otherwise, he wouldn't have been able to seal his remnant soul within the Soul-Devouring Blade for thousands of years.
Though sealed for countless ages, the evil Soul Master's soul had been nourished by the Golden Soul Essence, and his power had only grown stronger since his death.
Because of this, he didn't hesitate and immediately chose to invade Huo Yuhao's body to possess him.
However, what he didn't expect was that there was already another unfortunate soul inside Huo Yuhao with the same idea.
When the black thread successfully invaded Huo Yuhao's forehead, it finally sensed the presence of the silver flame.
"It's settled then—evil Soul Master's remnant soul! Use a spiritual attack on the silver flame!" Huo Yuhao shouted.
Evil Soul Master's remnant soul:
"Alright, alright, so that's how we're playing, huh?
"You released me, and I'm pleased, but now you're making things very difficult for me."
As a spiritual-type Soul Master, the evil Soul Master was extremely sensitive to the aura of the silver flame. After all, the moment he released a trace of spiritual energy, the flame immediately detected it and incinerated it, causing him excruciating pain.
Naturally, he also realized that this silver flame could burn spiritual power, leaving him speechless.
Are youngsters these days really so lacking in martial ethics? Tricking and ambushing an elder who's lived for thousands of years?
You little brat from the future, you're truly despicable!
"Don't even think about retreating now! Fight it out properly. I've been waiting for this dog-eat-dog show for ages!" Huo Yuhao chuckled.
A surge of powerful soul energy erupted from the black, ancient ring on his hand, sealing off the route for the evil Soul Master's remnant soul to retreat back into the Soul-Devouring Blade.
Now, retreat was no longer an option for the evil Soul Master. Even if he were stronger, going up against Elder Yao would be a death sentence.
Due to their opposing attributes, Elder Yao couldn't use his own soul power to help Huo Yuhao suppress the silver flame—that would be like adding fuel to the fire. But dealing with a remnant soul of an evil Soul Master? That was as easy as swatting a fly for him.
Meanwhile, the silver flame, which was trying to invade further, was blocked by the sudden appearance of the evil Soul Master's remnant soul, unable to continue its attempt to possess Huo Yuhao.
So, if it didn't give up on possessing Huo Yuhao, it had no choice but to first deal with the evil Soul Master's remnant soul.
"I've walked this path my whole life, but I never thought I'd lose to your dirty tricks," the evil Soul Master's remnant soul gazed bitterly at the silver flame rushing toward him, his voice now filled with ferocity.
"If you want to burn me to ashes, you'll have to lose half your life. Let me show you something you've never seen before—*
Sacred Teachings: Ring of Flames!"
