During the Qin Dynasty, he was in charge of the net.

"Your Majesty, without the Spirit Rhinoceros Jade Disc, how could Xiangfei and Xiangjun control the sect's protective formation?"

At this moment, Yan Fei, who was standing below Donghuang Taiyi, suddenly asked.

"I have my own plans for that."

Donghuang Taiyi replied casually.

Now Yanfei had nothing to say. Since His Majesty the Eastern Emperor had already made arrangements, it meant that these things were already within his expectations.

As for Xiangfei, who was involved, she also knew that what Donghuang said was not only for Yanfei, but also for her.

Since the ownership of the Lingxi Jade Disc has been determined, and His Excellency the Eastern Emperor has already made arrangements for the sect-protecting formation, Xiangfei has no choice but to accept this fact.

"Duan Shui, do you remember four days ago when I said I would give you a fortunate opportunity as a return gift?"

Donghuang Taiyi stood with his hands behind his back, his gaze fixed on Li Ji.

"Of course I remember."

Four days ago, after Li Ji entered the island and met Donghuang Taiyi, who gave him a congratulatory gift, the latter had said this.

Now Li Ji couldn't help but wonder if the return gift that Donghuang Taiyi mentioned was the Lingxi Jade Disc.

However, what Donghuang Taiyi said next made Li Ji realize that he was wrong.

"My Yin-Yang School has a supreme treasure called the Illusionary Sound Box."

This box is an ancient spiritual artifact, incomparable to ordinary magical implements. Those with an affinity for the arts will resonate with its spiritual energy upon touching it. Those without such an affinity will experience no reaction.

As Donghuang Taiyi spoke, he first looked at Da Siming and Xiangfei, and finally at Li Ji.

"Great Master of Fate, you have recently assumed the divine office of Yin and Yang, life and death. You may use the treasure box to solidify your foundation in the Dao of Life and Death and comprehend the art of judging fate."

Xiangfei, now that you have just assumed the position of goddess of the Xiang River, you may use the treasure box to contemplate the mountains, rivers, and marshes, and comprehend the Yin-Yang Dao of the water system.

"Duan Shui, your destiny is extraordinary. You are a person destined for my Yin-Yang school, and you can use this opportunity to comprehend the arts of Yin and Yang."

After saying that, Donghuang Taiyi lightly flicked his sleeve, and a pentagonal wooden box floated in the air before gently landing on the stone platform inside the hall.

This pentagonal wooden box is the most precious treasure of the Yin-Yang School, the Illusionary Sound Box.

After the treasure box landed on the stone platform, it slowly opened and transformed into a one-foot-long gilded pagoda.

This pagoda has five stories, corresponding to the five musical notes of the Chinese pentatonic scale (Gong, Shang, Jiao, Zhi, Yu), and each story has twelve eaves corresponding to the twelve musical scales (Qi).

The base of the tower is inscribed with sixteen Chu characters: "Twelve Illusory Laws, Five Modes of Non-Music, Heavenly Melody of Ultimate Bliss, Myriad Demonic Sounds."

Both Yan Fei and Yue Shen present had come into contact with the Illusionary Sound Box.

Only the newly appointed Grand Master of Fate, Xiangfei, and Li Ji had not come into contact with the Illusionary Sound Box.

However, to Yanfei and Yueshen's surprise, the Eastern Emperor was actually willing to allow an outsider to also come into contact with the Yin-Yang School's supreme treasure, the Illusionary Sound Box.

A hint of resentment flickered in Yan Fei's eyes. Although there were few assassins from the Yin Yang Clan's Luo Wang, she had only ever seen one who had been treated so well by the Eastern Emperor and allowed to access the treasure, the Illusionary Sound Box.

The Moon Goddess looked at Li Ji with a more inquisitive gaze. She believed that the Eastern Emperor had his reasons for everything he did, but they were too far removed from his level of understanding to comprehend it.

Li Ji never expected that the opportunity Donghuang Taiyi spoke of would be here.

He certainly wouldn't mind seeing the Yin-Yang School's most precious treasure.

However, he was not an ordinary assassin from the Luo Wang organization, but rather the successor secretly chosen by the leader of Luo Wang.

He had to guess Donghuang Taiyi's intentions: was it simply a return gift, or was there another purpose?

He wasn't sure how valuable the Primordial Yin-Yang Mysterious Jade given by the leader of Luo Wang was, but he felt that if he really wanted to return the favor, he should give it back to Luo Wang and its leader.

As for Donghuang Taiyi's so-called opportunity, is it a return gift to Luo Wang, or a personal favor to him?

Li Ji was inclined towards the latter.

Li Ji had already witnessed the wonders of Yin-Yang School magic in Donghuang Taiyi.

This is the kind of power that Li Ji needs.

Li Ji always felt a sense of urgency; the leader of the Luo Wang organization seemed to be making arrangements for him a little too hastily.

Can he really hand over these three important positions—Master of the Dark Execution Platform, Master of the Spy Bureau, and Head of the Killing Platform—smoothly?

Just as Li Ji was pondering, the Great Master of Fate had already begun to make contact with the Illusionary Sound Box.

"You go first, Grand Master of Fate."

Donghuang Taiyi raised his hand to Da Siming, the dark star patterns on his black robe shimmering with a faint light.

The Grand Master of Fate nodded slightly and walked to the stone platform.

She gently raised her hand, her jade-like fingers burning red, and placed them on the ancient surface of the Illusionary Sound Treasure Box.

The moment the Grand Master of Fate touched the Illusionary Sound Box with his fingertips, seven-colored light overflowed from the box, and rapid, sharp melodies poured out, like a sudden rainstorm hitting solid rocks.

The melody carried a fierce, resonant quality.

The Grand Master of Fate stood still, his body surging with fire, and a fiery pattern faintly visible between his brows.

The music lasted for five breaths, then abruptly stopped.

The High Priestess withdrew her hand and slowly returned to her original position.

"It's your turn, Xiangfei."

Xiangfei moved gracefully with light, lotus-like steps, and stepped out.

She wore a flowing, water-colored robe with cloud patterns, her steps light and slow as if treading on water. She slowly raised her fair hand and gently touched the surface of the Illusionary Sound Treasure Box.

In an instant, a clear and melodious zither tune, like the wind rising over Dongting Lake and the tide rising over Yunmeng, filled the hall.

A layer of warm, soft turquoise light emanated from the treasure box, enveloping Xiangfei.

Xiangfei's eyes widened slightly, as if she had witnessed something that surprised her.

The melodies emanating from the Illusionary Sound Box changed accordingly, like the gentle flow of the Yuan and Xiang rivers, or the low, melodious chanting of the "Songs of Chu," carrying an indescribable sense of melancholy.

After a full seven breaths, the music slowly faded away.

After the light faded, Xiangfei calmed herself down and stepped aside.

Finally, there is Li Ji.

He stepped forward, and as soon as his hand touched the Illusionary Sound Box, the box suddenly burst forth with a dazzling light interwoven with gold and purple.

Its aura flowed over Li Ji's entire body, its imposing presence far surpassing that of the previous Da Siming and Xiang Fei.

In an instant, a long, melodious tune surged forth from the treasure box.

At times, it is as sharp and cold as a drawn sword, carrying the chilling aura of war. At other times, it is as unpredictable as the rotation of yin and yang, seemingly both demonic and Taoist. And at still other times, it is like the roar of a dragon and the howl of a tiger, carrying a power that shakes the soul.

Inside the main hall, multicolored light flowed, and even the stone platform trembled slightly.

The melody lasted for a full fifteen breaths before slowly fading away, its lingering sound echoing around the beams for a long time.

The moment the treasure box fell, the hall fell silent.

The Grand Master of Fate and Consort Xiang stared in disbelief at the figure on the stone platform.

The longer one resonates with the Illusionary Sound Box, the higher one's talent in Yin-Yang magic, and the stronger one's understanding of Yin-Yang magic will naturally be.

The Grand Master of Fate has five breaths, while Xiangfei has seven breaths, which surpasses the vast majority of the Yin-Yang School.

Or rather, most people simply cannot resonate with the Illusionary Sound Box. For the five elders, reaching three breaths is considered passing, and reaching five breaths is considered excellent.

At this moment, Donghuang Taiyi on the high platform slowly spoke, his voice devoid of emotion: "Moon Goddess, Yan Fei, how long did it take for you two to resonate with the Illusionary Sound Box?"

The Moon Goddess bowed slightly: "Reporting to Your Majesty the Eastern Emperor, thirteen breaths."

Yan Fei stood to one side, her expression complex, and slowly said, "Fifteen breaths."
