Mortals cultivate immortality, I have a Chaos Tower

The night was deep, and the starlight sprinkled on the roofs of the village, as if covering this ancient and peaceful land with a veil. In the grotto in the village, Jiang Shuiling was sitting cross-legged on a flat stone, and there seemed to be some unique sound wave energy surging in the air around her.

Jiang Shuiling took a deep breath and immersed herself in the invisible sound waves around her. She seemed to hear subtle sounds, like waves hitting rocks or wind blowing through the woods. She tried to resonate with the sound waves, and the low bell sound during the battle with Cang Ming emerged in her mind - the power of the sound waves was so strong that it made people uneasy, and it could also be used to attack the enemy.

"If I can control this sound wave in my hand, perhaps it can become a powerful weapon..." Jiang Shuiling thought silently in her heart, and her spiritual power began to flow slowly along the fluctuations of the sound wave, trying to capture the mystery contained therein.

Just as she was concentrating on meditation, Zhong Ling'er noticed the changes in Jiang Shuiling and couldn't help but stepped forward and asked softly: "Shuiling, did you feel anything?"

Jiang Shuiling opened her eyes and nodded, with a thoughtful look on her face: "I seem to feel a special force... It's the fluctuation of sound waves. I'm trying to resonate with it."

Zhong Ling'er's eyes lit up and she showed an interested expression: "The power of sound waves? In that case, I will practice with you. Perhaps, we can learn how to control it together."

Jiang Shuiling smiled and said, "Okay, let's try it together."

The two sat opposite each other in the cave. Jiang Shuiling shared her feelings and thoughts with Zhong Ling'er, while Zhong Ling'er used her spiritual power to assist Jiang Shuiling, and together they captured the surrounding sound waves. The air in the cave gradually became a little heavy, and the fluctuations of spiritual power and sound waves intersected, as if forming an invisible melody that slowly flowed between the two.

"Ling'er, do you feel it?" Jiang Shuiling closed her eyes and spoke softly.

"Yes, I can feel this power flowing." Zhong Ling'er's voice also revealed a hint of excitement, "It is like a stream of water, constantly flowing around us. If we can master it, perhaps we can create a new means of attack."

The two continued to meditate, their consciousness wandering in the sound waves, trying to control these fluctuations. However, at this moment, Jiang Shuiling suddenly felt a unique energy gathering from all around. She suddenly opened her eyes, and the scene in front of her suddenly changed - the originally peaceful cave disappeared, replaced by endless darkness.

"Where is this?" Jiang Shuiling was shocked. She looked around but could not see any light. Only endless silence enveloped her.

At this moment, a soft silver light emerged from the darkness and gradually condensed into a mysterious spirit. The spirit emitted a faint silver light and looked ethereal, as if it would disappear into the air at any time. The spirit had no malice, but instead had an ancient majesty. It stared at Jiang Shuiling with a look of appreciation.

"You have touched the threshold of sound waves, but you have not yet truly mastered its essence." The spirit's voice was like a whisper in the wind, soft and distant. "If you can pass my test, I will grant you a deeper understanding."

Jiang Shuiling was slightly startled, and then her eyes became firm. She knew that this might be a rare opportunity. If she could pass the test, she might be able to master the real power of sound waves. She nodded without hesitation: "I am willing to accept your test."

The spirit smiled slightly, and a silver light flashed. The environment around Jiang Shuiling changed again. She was placed in an endless silence. There was no sound around her, only her own breathing echoing in her ears. The silent environment brought a strong sense of oppression, as if it was going to swallow her whole.

"Your trial is to feel the power of sound waves." The voice of the spirit sounded again, "In this boundless silence, feel it and control it. Sound waves of different frequencies will constantly impact your mind. You must learn how to adjust, absorb, and ultimately control them."

Before she finished speaking, Jiang Shuiling felt a strong sound wave coming from all directions. The force was invisible but heavy, as if it was going to completely break her mind. She gritted her teeth, tried to calm her mind, and tried to use her spiritual power to resist the impact of the sound wave. However, the frequency of the sound wave kept changing, sometimes low like the hum of the ground, and sometimes sharp like a knife. Jiang Shuiling's spiritual power became more and more chaotic under this unpredictable impact.

"This power... is too strong!" Jiang Shuiling felt her spiritual consciousness break apart in the sound waves, and cold sweat oozed from her forehead. She knew that she had to find a way to adjust, otherwise she would not be able to pass this trial.

Time passed slowly in the silent impact. Jiang Shuiling experienced failure again and again. Each time she felt exhausted, as if her whole body was torn apart. However, she never gave up. She knew that this was a test that she had to win. For herself and her companions, she had to break through this bondage.

"The power of sound waves... lies in resonance." Jiang Shuiling gradually realized the key to this after repeated attacks. She no longer tried to simply resist the power of sound waves, but let her spiritual power adjust with the frequency of the sound waves, trying to resonate with it.

Her spiritual power continued to flow in her body, gradually forming a subtle connection with the sound waves. The heavy sense of oppression gradually weakened, and the power of the sound waves was no longer a ruthless impact, but seemed to have become a part of her body, flowing in her spiritual consciousness.

"I understand..." Jiang Shuiling opened her eyes, and a glimmer of spiritual light flashed in her eyes. She took a deep breath and completely integrated her spiritual power into the sound waves. Her whole body seemed to turn into an invisible wave, blending into the surrounding space.

The spirit's voice rang in her ears again, with a hint of relief and appreciation: "Very good, you have understood the essence of sound waves. Sound waves are not just a means of attack, they can become a part of your body and the source of your power."

As the spirit finished speaking, the darkness around her gradually dissipated, and the scene of the cave reappeared in front of Jiang Shuiling. Zhong Ling'er was still sitting opposite her, looking at her anxiously.

"Shui Ling, are you okay? You suddenly fell into a strange state just now." Zhong Ling'er asked with concern.

Jiang Shuiling smiled slightly and nodded: "It's okay, Ling'er. I just went through a special trial, and now I have mastered the power of sound waves."

Zhong Ling'er looked at Jiang Shuiling's expression and knew that she had indeed made a breakthrough. She was surprised and relieved: "You are really amazing, Shuiling. You have surpassed yourself in such a short time."

At this moment, a silver light suddenly appeared in Jiang Shuiling's hand, and the silver light gradually condensed and turned into a scroll exuding an ancient atmosphere. The scroll was suspended in front of Jiang Shuiling, and the voice of the spirit sounded again: "This is the reward for your successful trial, the secret scroll of the sonic spell. I hope you can use it to protect everything you cherish."

Jiang Shuiling reached out to take the scroll, and felt the powerful sonic power contained in it. A hint of gratitude appeared in her eyes: "Thank you, I will definitely make good use of this power."

The spirit smiled slightly, and the silver light gradually dissipated, finally turning into a faint light and blending into the air, as if it had never existed.
