Chapter 150: The Sound of the Ultimate Heaven

Su Che was about to bid farewell when he heard the words spoken by the female Golden Core cultivator.
“As far as I know, among the team that entered the Underground Demon Realm a few days ago to gain experience, there were also several disciples from the Tianxuan Sect. I guess they are also at the Mojing Mine.”
The female Golden Core cultivator spoke slowly and gently, her tone in no way resembling that of a superior elder.
“Disciples from the Tianxuan Sect?”
Su Che’s heart stirred, and he immediately asked, “May I ask, elder, are those disciples from the Tianxuan Sect those at the foundational stage who went there to carry out a mission for exchange between sects?”
“Probably,” the female Golden Core cultivator nodded lightly. Having already noticed that Su Che was also at the early foundational stage, she asked, “Are you one of them?”
“No,” Su Che replied before pressing on, “May I ask again, elder? Do you know if among them is a male disciple with the dao name ‘Yu Qing’?”
“I’m not sure about that,” the female Golden Core cultivator replied patiently, unfazed by Su Che’s persistent questions.
At that moment, someone from the crowd nearby called out, “That’s right! There is indeed a disciple from the Tianxuan Sect with the dao name ‘Yu Qing’. A few days ago, he came to the Underground Demon Realm along with Senior ‘Zhu Feng’ and others.”
The speaker was a female disciple from the Wuji Sect. Mentioning ‘Yu Qing’s name made her show a hint of shyness.
Su Che realized it must be because of Yu Qing’s charm that she remembered his whereabouts so clearly.
“It seems likely that Senior Yu Qing is at that mine…” Su Che thought to himself.
Lao He muttered, “The bond between you and Yu Qing is really strange. You were separated in the sect for over three months, separated by vast distances, yet here in this underground world, you still ended up meeting again…”
Hearing Lao He’s words, Su Che couldn’t help but recall a question he had once had: “Back when I was still a self-practicing disciple, Senior Yu Qing took great care of me. But with so many outer sect disciples on Immortal Fate Peak longing to join Mysterious Secrets Peak, why didn’t he feel sympathy for them?”
At that moment, Su Che sensed that there must be some mystery behind this, though he wasn’t yet able to figure it out.
But anyway, Senior Yu Qing had done him a favor. Now that he knew Yu Qing was at that mine and might be involved in a great battle, Su Che certainly wouldn’t stand by idly.
It would have been fine if he hadn’t known, but now that he did, he would definitely go to join him and face all the difficulties together.

So, Su Che asked the Golden Core female cultivator, “Senior, since there are fellow disciples there, I’d like to go with you to join them. Is that okay?”
“Of course,” the Golden Core female cultivator nodded gently. “Then let’s go together.”
And so, Su Che set off toward the Ink Crystal Mine.
Along the way, the girl who wanted to ‘hunt’ Su Che approached him and asked in a low voice, “Senior, you’re only eighteen in bone age, right?”
“Mm, I’ll be nineteen soon,” Su Che replied softly.
“That’s amazing. I’m three years older than you, yet I’m only at the ninth level of Qi Cultivation,” the girl said with admiration in her eyes.
“You’re quite good too,” Su Che replied. He had already realized she had dual spiritual roots; reaching the ninth level of Qi Cultivation at such a young age was quite impressive.
Later, Su Che quietly asked, “How should I address the senior uncle who led you here for training?”
“Shh~~~” The girl put a finger to her lips and whispered, “He’s not a senior uncle; he’s the Patriarch.”
“The Patriarch?”
Su Che was slightly stunned. He thought to himself, “Among the top ten immortal sects, only great cultivators at the Yuan Ying stage can be called Patriarchs. That’s universal. Unless it’s…”
At that thought, he suddenly understood and quickly replied, “Could she be Patriarch Tianyin?”
“Mm!” The girl nodded firmly and whispered, “Surprised, right?”
“Yes, very much.”
Su Che murmured, nodding in shock.
He never expected her to be the famous and renowned Tianyin of the cultivation world…
“How could she be so approachable and kind?”
Su Che still found it hard to believe and asked again, “Is she really Patriarch Tianyin?”
“Of course!”
The girl pouted slightly and reminded him sourly, “Senior, you still don’t know my name.”
“Oh, my apologies.” Realizing he had been rude, Su Che asked, “What’s your name, junior sister?”
“My name is Song Ruxuan,” the girl replied sweetly.
After that, Su Che chatted with her intermittently, his mind still filled with awe at the name “Tianyin.”
Tianyin, who had reached the early stage of Golden Core at just 26, was recognized as the top genius in the cultivation world today. With water-type celestial spiritual roots, she was said to have great fortune and a naturally gifted cultivation body. From birth, she held a top-grade cultivation artifact in her hands.

There were also rumors that she was the reincarnated form of a high-ranking figure from the Wuji Sect, hence she held a status on par with an ancestral master within the sect. Su Che had surely heard of Tianyin’s name before, but he never expected her to be so gentle, graceful, and approachable. He had thought that a daughter of such noble origin would be aloof and disdainful toward everything… Thinking of this, Su Che couldn’t help but feel curious and asked again through telepathy, “Sister Song, since Ancestral Tianyin holds such an important position in your sect, how can the other ancestral masters of the Wuji Sect allow her to come to the Underground Demon Realm and take risks?”
“I don’t know,” Song Ruxuan shook her head and replied, “Anyway, ever since Ancestral Tianyin reached the Golden Core stage, she has led many disciples to the Underground Demon Realm for training every two months. Including this time… it should be the twelfth time.”
Su Che nodded silently. He had guessed that there must be a reason behind this, likely some personal secret of Tianyin’s. There surely was something extremely important for her in the Underground Demon Realm.
The large group continued onward. When they were still about ten miles away from the Ink Crystal Mine, they could already see colorful magical flames glowing on the mountain, indicating that the battle there was already quite intense.
The Underground Demon Realm was dimly lit, and it was precisely for this reason that the magical flames could travel farther.
“Fly low and hurry over,” Tianyin’s gentle voice echoed in everyone’s ears.
“Yes,” the disciples replied in unison.
The ten-mile distance could be covered in the blink of an eye. However, as they neared the Ink Crystal Mine, a cluster of dark clouds appeared from the right—clearly a small group of Flying Night Demons.
Tianyin, flying at the front, turned to the more than twenty Foundation Establishment disciples behind her and ordered, “You go and stop that group of Night Demons first, then gather at the mine.”
“Yes, Ancestral Master.”
The twenty-plus Foundation Establishment disciples changed direction, separated from the group, and rushed toward the distant Flying Night Demons.
After all, they were Foundation Establishment disciples from a top-tier sect. Even if they had to fight two enemies at once, they should be able to win. With coordinated tactics, eliminating that group of Night Demons shouldn’t be a problem.
Boom! Boom! Boom…
When the two groups were nearly a hundred feet apart, the twenty-plus Foundation Establishment disciples of the Wuji Sect already took action.
“Heaven and Earth without End!”
With a unified command, the twenty-some of them simultaneously launched their flying swords.
“Heaven and Earth in Perpetual Flux!”
Another command, and in an instant, twenty-some identical magical shields rushed out, forming a fan-shaped, impenetrable defensive wall.
Boom!

Dozens of Flying Night Demons swung their steel spears and charged forward with wild howls…
On this side, the many Qi Cultivation disciples of the Wuji Sect gazed at the battles of their senior brothers with awe-filled eyes. In their view, those at the Foundation Establishment stage already possessed unimaginable strength.
But in Su Che’s eyes, the coordinated offensive and defensive tactics of those Foundation Establishment disciples were impressive yet full of flaws. If it were him, he could instantly find multiple ways to evade their attacks and break through their defenses…
Thinking of this, Su Che suddenly realized that although his cultivation level was still in the early Foundation Establishment stage, his vision and mindset had far surpassed those of those disciples.
“This is because…”
“Yes, master,” Old Hei agreed. “After experiencing that Thunder Dance at the Eye of Wind and Thunder, your mental realm has risen several levels, and your control over your own power has reached a highly refined state.”
“A highly refined state…”
Su Che smiled silently, recalling once again the scenes of him dancing lightly alongside the thunder.
At that moment, monstrous flames blazed at the Ink Crystal Mine. Over a hundred Flying Night Demons flapped their wings, carrying dark winds as they bombarded a mine tunnel below.
“The people from the Wuji Sect are trapped in that mine tunnel. Without reinforcements, they will truly perish here,” Su Che guessed. “I wonder if Senior Yu Qing is also inside the mine.”
After all, this was the underground demonic realm, where more and more demons appeared, leaving human cultivators increasingly outnumbered and struggling harder.
“Ugh…”
Many Night Demons had already spotted Su Che’s reinforcement team and immediately sent over thirty of them to intercept them.
Whoosh!
A stunning figure accelerated instantly. Tian Yin didn’t use any flying magic artifacts; her robes fluttered as if she were a celestial fairy descended to the mortal world, flying straight toward those ferocious and vicious Night Demons.
Swish! A light blue aurora erupted from her hand, instantly spreading into a blanket of ice mist that enveloped the thirty-plus Night Demons.
“Ice Seal for Thousands of Miles!”
Su Che was also quite familiar with this spell. On the day he was chased by the Black Fiend, he had used three top-tier spirit talismans of “Ice Seal for Thousands of Miles.”
However, the effect of the spirit talismans was vastly inferior to what he saw today. If Tian Yin’s attack could be called “Ice Seal for Thousands of Miles,” then the power of those top-tier spirit talismans could only be considered “Ice Seal for a Hundred Miles.”
Huh!

An ice mist swept in, and the thirty-some nightmares, screaming loudly, instantly froze mid-air, each maintaining a fixed posture, turning into over thirty pale blue ice sculptures.
In that brief instant, even Su Che, as a bystander, felt as though he too had been frozen into an ice sculpture—his mind, his thoughts, even time itself, all frozen…
That short moment seemed to stretch infinitely, with no end in sight.
“No!”
For some reason, a roar of anger burst from Su Che’s heart, as a fierce desire to resist and struggle surged forth instantly.
Tian Yin, who was dozens of feet away, had merely made a casual strike—not even aimed at Su Che—but it still induced an irresistible, terrifying illusion in Su Che’s mind.
It seemed far more terrifying than the countless thunderbolts in the Wind and Thunder Desolate Land…
Su Che’s reaction was so intense, but why did the others around him simply gaze at Tian Yin’s back with admiration, their expressions completely normal, without any adverse reactions like Su Che’s?
Why was that?
“What’s wrong with the master?” In the Immortal Prison, Lao He was also puzzled.
