In the main hall, Luo Heng held the dark golden key and glanced at the four Lin Dong.
"You can wait for me here, or you can go back to Yang City first, but pay attention to safety."
Lin Dong nodded and said, "Brother Luo Heng, don't worry, we'll wait here."
Mo Ling The three of them also nodded.
Luo Heng didn't say anything more, a trace of Primal Energy spilled from his fingertips and poured into the key.
"Buzz--!"
The key trembled suddenly, and a beam of light shot out from it and shot into the air.
The beam of light spread rapidly in mid-air, and soon turned into a space channel several feet in size, exuding a faint fluorescent light.
Luo Heng stepped in and disappeared into the passage.
However, the moment his figure disappeared--
A fiery red figure suddenly burst out from the darkness of the hall and headed straight towards the slowly closing space passage!
It was a girl in a red dress, with a charming and delicate face, her black hair hanging down like a waterfall, and a faint aura of flame lingering around her body.
It's ordinary Nirvana Stage, but its breath is even stronger than the previous Chen Mu.
"Huh? The space channel is not closed yet!"
A hint of surprise flashed in her eyes, her speed suddenly increased, and she was about to rush into the passage.
But the next second--
An invisible Spiritual Power barrier, like an invisible wall, hit her hard!
"Bang!"
The girl in the red dress was caught off guard, and was knocked upside down. She did some somersaults in the air before she could regain her balance.
She clutched her lower abdomen, a look of pain flashed across her face.
"Ouch! It hurts!"
On the other side of the space channel, a faint voice came.
"This is not a good habit."
There was a hint of smile in Luo Heng's voice.
The girl in the red dress looked up and saw that the space passage had been completely closed, leaving only a void.
She was stunned for a moment, then curled her lips.
"Cheapskate!"
She muttered and rubbed her painful belly, but a strange color flashed in her eyes.
Half-step Two Yuan Nirvana.
Low-rank Dynasty? Isn't this strength too outrageous?
She originally thought that with her strength, Ancient Battlefield Northwest Region could walk sideways here.
But he didn't expect to encounter such a monster.
"Mu Hongling ah Mu Hongling, you are so unlucky." She laughed to herself.
But then, a hint of excitement flashed in her eyes.
"But... we can't just let such an interesting person go."
She turned around and looked at the four Lin Dong in the hall, with a bright smile on her face.
"Hey, you guys are that guy's companions, right?"
Lin Dong The four of them looked at each other and looked at her warily.
Mu Hongling didn't care, and waved his hand with a smile.
"Don't be nervous, don't be nervous, I'm not a bad person."
She paused, a hint of cunning flashed in her eyes.
"By the way, what's that guy's name?"
Lin Dong was silent for a moment, and then said, "Luo Heng."
"Luo Heng..." Mu Hongling murmured and repeated, then smiled and said, "Remember! Next time we meet, I must let him compensate me!"
After saying that, she turned around and left, her fiery red skirt drawing a graceful arc in the air.
Lin Dong The four of them looked at her back and looked at each other.
Where did this woman... come from?
Within Secret Key Space.
The figure of Luo Heng appeared in an extremely vast square.
The square is made of black rock, exuding antiquity and depth, and every stone slab underfoot is engraved with the traces of time. Looking up, the surroundings are dark, with only a faint flicker of light in the center of the square.
Luo Heng's eyes were directly fixed on the center of the square.
There, a figure sat cross-legged.
It was an old man in gray robes, with a haggard face, his eyes closed, and his whole body exuded the aura of death.
Obviously, this is a remains.
Luo Heng moved and appeared in front of the remains in an instant.
The remains are quite well stored, and although the face is shriveled, it can still be seen that they are exactly the same as those stone statues in the Stone Hall.
Luo Heng's eyes fell on the hands of the remains.
There, an ancient yellow key lay quietly.
The key is about the size of two palms, and its material is somewhat special, resembling wood but not wood. The surface is filled with some peculiar lines, and there is a faint, palpitating wave coming from it.
Ancient Key.
But Luo Heng didn't reach out for it immediately.
His Spiritual Power has already spread like a tide, covering the entire space.
Within the remains, he sensed an extremely weak wave.
That is a soul.
Although it was extremely hidden, there was nothing to hide from Luo Heng's spiritual power, which was comparable to that of the Three Seal Talisman Master.
"Interesting."
Luo Heng A smile appeared at the corner of his mouth.
This soul should be the owner of this remains.
In life, it was at least Five-Seal Heavenly Talisman Master, or even stronger.
The remaining soul after death is hidden in the remains, waiting for the destined person to come and get the secret key, and then take the opportunity to take the body and be reborn.
Among Original Work, Lin Dong almost hit the road.
It's a pity...
Met him.
"Come out."
Luo Heng said lightly.
The soul trembled slightly, but there was no movement.
Luo Heng smiled.
He raised his right hand and held it with five fingers.
Peak One Seal Rune Master's Spiritual Power, like the power of heaven, violently suppressed the remains!
"Boom--!"
The remains trembled suddenly!
An illusory soul body was shaken out of the remains!
It was an old man who was exactly the same as the remains, but his figure was illusory and he exuded faint soul fluctuations.
At this moment, his illusory face was full of horror.
"You... you are Heavenly Symbol Master too?!"
His voice was trembling with endless fear.
Heavenly Symbol Master!
And it's Spiritual Power's extremely powerful Heavenly Symbol Master!
This kind of existence is simply a natural enemy for a remnant soul like him!
Luo Heng didn't answer, he just raised his right hand and shook it lightly.
The invisible Spiritual Power turned into a big hand and pinched the soul's neck fiercely.
"Uh-huh--!"
The soul body let out a shrill scream, and the illusory body twisted violently, as if it would break at any time!
"Spare your life! Senior, spare your life!"
He begged frantically for mercy, his voice full of fear.
"I am willing to surrender! I am willing to serve my senior! I beg your senior to spare my life!"
Luo Heng looked at him without any fluctuation in his eyes.
"Surrender? Serve?"
He shook his head.
"No need."
As soon as he finished speaking, his Spiritual Power suddenly increased in size!
The screams of the soul body were even more shrill, and cracks began to appear in the illusory body, as if it would collapse at any time!
"No--!"
He struggled wildly, but couldn't break free from Luo Heng's Spiritual Power restraints.
At this moment, a terrifying suction force suddenly erupted from Luo Heng's body!
Great Devouring Art, full operation!
That suction force directly acted on the soul body and began to devour the power of his soul crazily!
"Ah--!!!"
The screams of the soul body resounded throughout the space, but became weaker and weaker...
After a while.
Everything returned to calm.
That soul body completely dissipated.
And Luo Heng slowly closed his eyes.
A huge soul power poured into his Niwan Palace like a torrent.
That was the soul origin of that soul body during its lifetime. Although most of it has been lost over the years, the remaining part is still very impressive.
Luo Heng runs <Art of Soul Refining> and begins to frantically refine this soul power.
Time passes minute by minute.
I don't know how long it took--
Luo Heng Open your eyes.
At that moment, a golden light seemed to flash in his eyes.
Among the Niwan Palace, Myriad Law Seal shines brightly, becoming more solid and profound.
Half-step Two-Seal Heavenly Talisman Master, done!
Luo Heng felt the surge of Spiritual Power in his body, and a satisfied smile appeared at the corner of his mouth.
This trip is worth it.
The soul power of that soul body not only allowed him to break through to Half-step Two-Seal Heavenly Talisman Master, but also further improved the quality of his Spiritual Power.
Now his Spiritual Power is only half a step ahead of the Two-Mark Realm, but its quality is already comparable to Four-Seal Heavenly Talisman Master!
If he encounters the Nirvana Stage ant from before again, he doesn't even need to make a move, he can make the other person's soul fly away with just one look.
"Not bad."
Luo Heng nodded.
Then, he closed his eyes and began to digest the remaining martial arts information in his soul body's memory.
That soul body was indeed a Five-Seal Heavenly Talisman Master during his lifetime.
Although most of the memories have faded over the years, some core inheritance has still been preserved.
After a while, Luo Heng opened his eyes, a hint of surprise flashed in his eyes.
In the remaining memory, he discovered a powerful spiritual skill.
<Nine Transformations of the Heavenly Soul>.
Divine Level Mental Secret Technique, divided into nine changes.
The first change, Soul Transformation, can make Spiritual Power temporarily increase by 30%.
The second change, Soul Escape, allows the soul to instantly escape from the body and avoid fatal attacks.
The third change, Soul Kill, can directly launch attacks with the soul, and its lethality far exceeds ordinary spiritual skills.
The fourth transformation and above involve the transformation of the soul's origin, and the information is incomplete and cannot be practiced.
But only the first three changes are powerful enough.
Especially the third transformation Soul Kill, with his current Spiritual Power, it is enough to instantly kill the ordinary One Seal Rune Master!
"Good stuff."
Luo Heng Memorize this secret skill and prepare to practice it slowly after returning home.
Then, he looked at the key in the remains' hand.
Ancient Key.
The real secret key.
He reached out and picked up the key.
The hand is slightly heavy, and the material is special. It looks like wood but not wood, and looks like gold but not gold. The texture on the surface seems to be formed naturally, and there is a faint sense of the flow of heaven and earth.
"Got it."
Luo Heng takes the key to System Space.
He stood up, took one last look at the space, then turned around and walked in the direction he came from.
Behind him, the square remained silent.
The remains were still sitting cross-legged.
It's just that the soul in the body has completely dissipated.
