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

What appeared before everyone was a deep blue pool of water, still and undisturbed, like a huge blue mirror, reflecting the gray sky and making it appear even more profound. However, this seemingly calm pool of water exuded a chilling aura that made one's heart tremble.

Even before getting close, one can feel a bone-chilling cold rushing towards them. Thick frost has formed on the surrounding rocks, and even the air is filled with tiny ice crystals that shimmer with a ghostly blue light in the dim light.

Lu Lingxi walked to the edge of the pool, squatted down, and gently touched the water with her hand.

"hiss……"

The chill emanating from her fingertips made her gasp. This coldness not only affected her body but also penetrated her meridians, reaching her dantian, as if it were freezing all the spiritual energy within her body.

"What domineering cold air!" Lu Lingxi was secretly shocked. This Netherworld Cold Pool was indeed worthy of its reputation.

Bai Xiaochen explained from the side, "The water in this Netherworld Cold Pool is formed by the gathering of extremely Yin energy inside the Yellow Spring Tomb. It contains powerful purifying power. This purifying power can cleanse the impurities in the cultivator's body and improve the purity of spiritual energy. However, this cold energy is also extremely domineering. If one cannot resist it, at best one's spiritual energy will be damaged, at worst one's meridians will be severed, and one's life may even be endangered."

"So dangerous?" Huan Yue shrank her neck, looking at the Netherworld Cold Pool with some fear.

"What's there to be afraid of? I'm here." Zhuque said nonchalantly. She walked to the edge of the pool, took a deep breath, and a blazing phoenix fire ignited around her, dispelling the surrounding chill.

"This first trial is to test the purity of our spiritual power." Lu Lingxi stood up and said to everyone, "We need to enter the cold pool and use the pool water to purify our spiritual power. Only when our spiritual power reaches a certain purity can we pass the test."

"Then what are we waiting for? Let's get started!" Suzaku was eager to try, and she was very confident in her phoenix fire.

"Everyone be careful. The cold air in this pool is extraordinary. Don't be reckless," Lu Lingxi Yao reminded.

After Lu Lingxi finished speaking, she took off her shoes and socks and stepped into the cold pool. The icy water instantly submerged her feet, and the biting cold felt like countless steel needles piercing her skin and spreading rapidly throughout her body along her meridians.

Lu Lingxi quickly circulated the spiritual energy within her body to resist the erosion of the cold air. The nine elemental spiritual energies flowed within her body, forming a solid defense that blocked the cold air from entering.

However, the cold air was too domineering, and even Lu Lingxi felt a bit strained. She had to divert some of her attention to guide the purifying power in the pool water to cleanse her own spiritual energy.

The purifying power entered her body like a raging fire, burning away the impurities in her spiritual energy. Lu Lingxi felt waves of intense pain, but she gritted her teeth and silently endured it.

Zhuque followed closely behind and entered the icy pool. Phoenix fire burned around her, causing the pool water to boil. Phoenix fire is extremely yang and strong, and is the nemesis of cold air. Therefore, Zhuque seemed to move with ease in the icy pool.

While resisting the cold, the Vermilion Bird guided the power of purification to cleanse its own spiritual energy. Under the effect of the purification power, the Phoenix Fire became purer and hotter.

Huan Yue mustered his courage and entered the icy pool. He activated the wind and fire spiritual energies within his body, forming a whirlwind that blocked the cold air from the outside. The wind and fire complemented each other, doubling their power. Although Huan Yue was somewhat strained, he was able to barely hold on.

He carefully guided the purifying power into his body, cleansing his spiritual energy. Under the effect of the purifying power, the wind and fire spiritual energies gradually merged and became more refined.

Bai Xiaochen also entered the cold pool. Although he was not as strong as Lu Lingxi and the others, he was quite familiar with the Yellow Spring Tomb and had mastered some special techniques. He took out a jade talisman from his storage bag and stuck it on his body. The jade talisman emitted a soft light, forming a protective shield that kept the cold air out.

He guided the power of purification into his body, cleansing his spiritual energy. Although his spiritual energy was impure, it gradually became pure under the effect of the power of purification.

In the end, only Phantom remained, standing by the pool, hesitant and undecided.

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

“Master, I…” Phantom hesitated, his face pale and beads of sweat on his forehead.

"The demonic energy and the cold here... are making me very uncomfortable..." the phantom said intermittently.

Lu Lingxi then remembered that the phantom was the Demon Blood Vine. Although it had recognized her as its master, the demonic energy within it had not been completely eliminated. The cold air of the Netherworld Cold Pool could purify spiritual energy, but it posed a huge threat to demonic energy.

“Phantom, don’t push yourself. Wait for us on the shore,” Lu Lingxi said.

“No, Master, I can do it.” Phantom shook his head, his eyes filled with determination. “I can’t hold everyone back.” He took a deep breath and stepped into the icy pool.

The icy water instantly submerged his feet, and the biting cold and dense demonic energy assaulted him simultaneously, causing him to shiver involuntarily.

Under the dual stimulation of the cold and demonic energy, the spiritual power within the phantom's body began to stir restlessly. He felt waves of excruciating pain, as if countless ants were gnawing at his meridians.

"Phantom!" Lu Lingxi exclaimed, wanting to step forward to help the phantom, but was stopped by Zhuque.

"Don't go over there. He's in a dangerous situation right now, and you won't be able to help him," Zhuque said.

Lu Lingxi looked anxiously at the phantom, who was clenching his teeth, his eyes were bloodshot, and his body was trembling slightly, as if he was enduring great pain.

Under the combined influence of the cold and demonic energy, the spiritual power within the phantom's body began to mutate. The originally bright red vines gradually dimmed, and some even began to wither.

However, as the vines withered, new shoots emerged from them, displaying a strange, ethereal blue color and emitting a faint glow.

The phantom felt his consciousness begin to blur. He seemed to see countless illusions: bloody battles in the demon realm, love and hate among humans, and some scenes he had never seen before.

In the illusion, he saw a huge demonic blood vine, which covered the sky and emitted a monstrous demonic aura. This demonic blood vine seemed to be his own body, or perhaps his ancestor.

The Blood Vine stretched out countless tendrils towards him, seemingly trying to devour him. The phantom felt a surge of fear; he wanted to escape, but found himself completely unable to move.

Just as he was about to be devoured by the Demon Blood Vine, a warm light suddenly appeared before him. This light was Lu Lingxi Yao's spiritual power.

Lu Lingxi Yao's spiritual power, like sunlight, dispelled the darkness and warmed his heart. The phantom's consciousness gradually returned, and he saw Lu Lingxi Yao's anxious eyes and heard her concerned voice.

"Phantom, hold on! Don't give up!" Lu Lingxi's voice, like heavenly music, entered Phantom's ears.

The phantom's eyes gradually regained their clarity. He took a deep breath, circulated his spiritual power, and resisted the erosion of the cold and demonic energy. He guided the power of purification into his body, and the demonic energy gradually subsided under the effect of the purification power, but his power also weakened.

As time passed, the phantom vines gradually changed. The originally dull vines regained their luster, and the newly sprouted buds became even stronger.

A ghostly blue light emanated from the phantom, dispelling the surrounding chill. Under the dual tempering of the chill and demonic energy, he actually underwent a transformation.

"It's a success!" Phantom suddenly opened his eyes and exclaimed in surprise. He felt his body was filled with power, a power that seemed stronger than ever before.

"Phantom, how are you feeling?" Lu Lingxi asked with concern.

“Master, I’m fine,” Phantom said with a smile. “I have completed the purification, and now I am no longer afraid of the cold here.”

"That's good." Lu Lingxi Yao breathed a sigh of relief.

One by one, the group emerged from the icy pool, each radiating a purer spiritual energy. They knew they had passed the test of the Netherworld Cold Pool and were one step closer to the Root of the Yellow Springs.

Bai Xiaochen looked at everyone and said, "The trial at the Netherworld Cold Pool is over. Next, we're going to the Rebirth Mirror Array."

"The Mirror of Rebirth?" Lu Lingxi frowned slightly. "What kind of place is that?"

“The Mirror of Rebirth is the second trial in the Tomb of the Underworld, and also the most dangerous one,” Bai Xiaochen explained. “In the Mirror of Rebirth, we will see our past and present lives and experience various illusions. If we cannot maintain our true nature, we will be lost in the illusions and never wake up.”

"Past life or present life?"

Lu Lingxi felt a pang of sadness and took a deep breath. She then walked towards the Rebirth Mirror Array first, followed closely by Zhuque, Huanyue, Huanying, and Bai Xiaochen, each with a solemn expression on their face.
