Genius in the whole system: The useless young lady dominates the world

After discussing it for a while, the three decided to let the phantom test the strength of the restriction first, so they summoned the phantom out of the space.

“Phantom, you are quite sensitive to the aura of the Yellow Spring Root, why don’t you give it a try?” Lu Lingxi said.

Phantom nodded, took a deep breath, and slowly approached the Root of the Underworld. As he got closer, his spiritual power began to fluctuate. His hands transformed into vines, with fine black patterns appearing on their surfaces, and a faint demonic aura emanating from them.

“Ugh…” A look of pain appeared on Phantom’s face, as if he was trying his best to suppress some kind of power within his body.

"Phantom, what's wrong?" Lu Lingxi noticed Phantom's unusual behavior and quickly asked.

"I...I feel like the power inside me is about to get out of control again..." Phantom's voice trembled slightly as he clutched his chest tightly, cold sweat beading on his forehead.

Lu Lingxi was startled, realizing that the demonic energy of the Yellow Spring Root had strongly stimulated the phantom's spiritual power.

"Phantom, step back first!" Lu Lingxi said.

However, Phantom seemed not to hear her words and continued to approach the Root of the Underworld step by step. His eyes were full of struggle and pain, but his steps never stopped.

"Phantom!" Lu Lingxi's voice rose a few decibels as she tried to step forward to stop the phantom, but Zhuque held her back.

"Don't go over there. Something's wrong with Phantom. You might be in danger if you go over," Suzaku said.

Lu Lingxi gritted her teeth. She knew Zhuque was right, but she couldn't just stand by and watch the phantom fall into danger again.

Just then, the phantom walked up to the root of the underworld. It stretched out its hands, which had turned back into vines, and slowly wrapped them around the root of the underworld. The moment it touched the root of the underworld, a strange change occurred!

The runes and array patterns that were previously faintly visible suddenly lit up, forming a powerful energy barrier that sealed off the entire space. At the same time, dense black demonic energy surged from the Yellow Spring Root, like a flood bursting its banks, instantly engulfing the phantom.

"Illusion!" Lu Lingxi and Zhuque exclaimed at the same time. They tried to rush over, but were blocked by the energy barrier and could not get close.

"Damn it!"

Lu Lingxi slammed her fist into the energy barrier, producing a muffled thud, but the barrier remained completely still, and her heart sank to the bottom.

"This restriction is incredibly powerful!" Zhuque's expression was also quite grim.

The demonic energy grew increasingly dense, completely enveloping the phantom and obscuring its form. The demonic energy began to churn, as if something was about to burst forth from within.

"Roar!"

Then, a deafening roar came from the churning demonic energy, causing the entire Yellow Spring Tomb to tremble slightly. The once relatively flat ground cracked inch by inch, spreading out like a spider web.

Lu Lingxi felt a powerful wave of energy rush towards her, almost making her lose her balance. She subconsciously raised her hand to shield herself, but she could still feel the violent demonic energy, like countless tiny steel needles piercing her skin, bringing waves of stinging pain.

As the demonic energy gradually dissipated, the handsome young man in the phantom had vanished, replaced by a giant vine tens of feet tall, with a thick trunk, pitch black as ink, and its surface covered with twisted patterns, like hideous blood vessels.

Countless vines extended from the main trunk, waving wildly in the air, each vine thicker than a bucket, covered with sharp barbs that gleamed with a cold, eerie light. The tips of the vines forked like the tongues of venomous snakes, dripping black liquid from time to time and emitting a nauseating, fishy stench.

"The phantom...it's actually the Soul-Devouring Demon Vine!" Lu Lingxi Yao said in shock, her eyes filled with disbelief.

Suzaku and Huan Yue were equally shocked. They had never imagined that the true form of the phantom was actually the Demon Realm's sacred artifact—the Soul-Devouring Demon Vine.

The Soul-Devouring Vine is one of the most terrifying plants in the legendary demon realm. It possesses the powerful ability to devour souls. It feeds on demonic energy and grows extremely fast. Once mature, it possesses the power to destroy the world.
