With a wave of her hand, the zither instantly appeared in her arms. Lu Fuyue casually sat on the ground, closed her eyes, and slowly began to play the zither in rhythm with her heartbeat.

Gradually, her music broke free from the constraints of the score and the rules accepted by the world. She played and moved as she pleased, and came to understand her own score, "Taiyin Yuehua".

The Moonlit Essence of Taiyin allows her to absorb the power of Taiyin at night, summoning Yin soldiers of the same rank as herself to serve her. The higher her cultivation level, the more numerous and powerful the Yin soldiers she can summon.

Suddenly, everything around her seemed to lose its color, leaving only her and the zither in her hands. The grass beneath her feet was gone, the stars in the sky were gone, and not even a trace of life remained.

But this is the essence of her philosophy!

A bright moon suddenly appeared in the night sky, and within his dantian, a wisp of gray energy quietly emerged.

At the same time, the white Yin energy surged into Lu Fuyue's body like a tide as she played the zither, flowing through her meridians and internal organs.

The Water Spirit Saint Body is Yin in nature, and the power of Taiyin is exactly the same as its attribute. The wisp of gray chaotic energy attached itself to Lu Fuyue's heart bone.

In no time, Lu Fuyue's bones began to change, gradually becoming tinged with golden-red flames. Tiny impurities emerged from the surface of the bones, forming a thin layer on top.

Lu Fuyue circulated her cultivation technique, guiding the changes in the spiritual energy within her body little by little.

The wisp of chaotic energy within her body was a great opportunity casually given to her by the female immortal in green robes that Lu Fuyue encountered in the Cangnan Secret Realm.

Normally speaking, with her current cultivation level, she simply cannot refine the chaotic energy. If she were to forcibly refine it, it would only lead to her body exploding and her death.

However, since Lu Fuyue's true form is the divine beast Phoenix, her physical strength far surpasses that of cultivators of the same level. In addition, the Taiyin power that Lu Fuyue obtained through enlightenment today caused the Water Spirit Holy Body to evolve into the Water Spirit Divine Body again, which is why she was able to activate the chaotic energy within her body.

However, she could only touch a little bit of the power of the chaotic energy, and could not refine it.

After an unknown amount of time, when Lu Fuyue awoke again, her phoenix wings had faded, and she had returned to human form. Her recently achieved peak mid-stage Golden Core cultivation had also become increasingly solid.

Lu Fuyue carefully sensed the changes within her body and suddenly discovered that a small bright moon was hanging high above her dantian; in the very center of her dantian, the Yin-Yang Tai Chi diagram of life and death was constantly rotating, and in the center of the Tai Chi diagram was a white bead.

In addition, a wisp of gray chaotic energy floated above the Taiji diagram, the Weak Water Zither was located below the gray energy, and a white stream of energy flowed over these things.

Then it transforms into pure spiritual energy, which is fed back into Lu Fuyue's body, and so on in a continuous cycle.

Lu Fuyue closed her eyes and could still clearly feel that even without cultivating, her cultivation level was gradually increasing, and the spiritual energy from the outside world was constantly entering her body.

This is the terrifying aspect of the Water Spirit Divine Body; even without cultivation, its cultivation growth rate is equivalent to that of a high-grade spiritual root.

During this seclusion, Lu Fuyue not only reached the peak of the middle stage of the third level of body refinement, but also successfully evolved her physique, obtained the power of Taiyin, and comprehended the zither score.

Lu Fuyue originally wanted to leave seclusion, but suddenly remembered that although she had spent a hundred years in the space during this cultivation, only a year had passed outside.

Cultivators often go into seclusion for decades or even thousands of years, but she has only been in seclusion for a year, so naturally she is not in a hurry to come out.

So Lu Fuyue started playing the zither score she had just comprehended again in the space.

The Moon's Essence, if used properly, can be a great asset to her. If she is surrounded and attacked again like last time, she won't have to fight alone.

A few days later, the body of the Weak Water Zither trembled slightly. Lu Fuyue paused in her movements, put away the zither, stood up, and looked at the person who had come in. "Shui Ze, you're awake?"

A tall, azure-blue figure appeared instantly. He looked up at her and said, "I thought I would have to sleep for another hundred years, but I didn't expect that your enlightenment this time would benefit me as well, ending my slumber ahead of schedule."

Lu Fuyue smiled faintly, "This sudden enlightenment has indeed been very rewarding."

Shui Ze suddenly fell silent for a moment. “Fu Yue, don’t touch that golden string on the Trial Tower for now. The situation inside is unclear, and your current strength is not enough to step into it.”

"Taking action rashly will only result in more harm than good."

A hint of surprise flashed in Lu Fuyue's eyes. If Shui Ze could say such a thing, then what exactly was hidden in the ninth level of the Trial Tower?

She thought for a moment and then slowly said, "But I only have a little over two hundred years left to live. If I don't get this golden string, I'm afraid I'll die before I can find the next one."

Shui Ze walked over to Lu Fuyue and sat down. “I have found the location of the other string. Why don’t you go there first and get that string? You can come back for this string after your cultivation reaches the Nascent Soul stage.”

Lu Fuyue sat down as well, poured him a cup of Enlightenment Tea, and handed it to him, "Really, where is that string?"

Shuize blocked the tea she was offered with his hand, saying, "This tea isn't suitable for me. You should drink it yourself."

Lu Fuyue was taken aback. She had forgotten that the water spirit was no different from ordinary tea to him. But for cultivators, it was a priceless treasure for sudden enlightenment.

However, the Enlightenment Tea can only be used once every hundred years; otherwise, it is of little use.

Lu Fuyue did not take back the teacup, but looked up at him and said, "If you don't drink it now, you won't be able to drink it tomorrow. Just treat it as ordinary tea to quench your thirst."

Shui Ze thought for a moment, then suddenly laughed, "That's true."

The tea is now useless to both of them, and they can't give it to others to drink, so it has naturally become just ordinary tea.

Shui Ze picked up the teacup with her well-defined knuckles and took a few sips. The first taste of the Enlightenment Tea was slightly bitter, but after a few seconds, a sweet aftertaste lingered on her lips and teeth. It was indeed a fine tea.

However, for him, it was of no use other than tasting better.

What would it feel like if the person outside knew that what they considered a rare treasure was simply drunk like ordinary tea?

"The other string is of the fire element and is located in the underworld."

Lu Fuyue's eyes flickered slightly, and she pursed her lips. "The Underworld?"

"Yes, it's the underworld."

Shui put down her cup and looked at Lu Fuyue. "If you want to improve your cultivation, besides constantly practicing, there is another way. That is to find the remaining three strings as soon as possible. In this way, when each string is put back in place, you will receive spiritual power from the string, thus continuously breaking through."
