Chapter 151: The Ink Crystal Cave

Tianyin’s “Ice Lock Thousand Miles” spell froze over thirty Yakshas into ice sculptures.
Then, she slightly parted her red lips and uttered a single word:
“Duo!”
Whoosh~~~ A visible sound wave suddenly appeared, spreading outward in a fan shape.
Crack……
The thirty-plus ice sculptures of Yakshas shattered instantly, turning into countless tiny ice shards that clattered to the ground.
In this way, those fierce Yakshas were effortlessly sent to hell by Tianyin.
At that moment, Su Che had just regained consciousness, his eyes filled with shock as he stared intently at Tianyin’s back……
“Master, what just happened?” Lao He asked anxiously. “Although Tianyin’s attack was powerful, it shouldn’t have caused you to lose control like that.”
“I don’t know… Wait, wait…”
Su Che immediately focused inward and discovered that the drop of Witch Clan blood in his right atrium was trembling slightly. His loss of control must have been caused by it.
“Tianyin’s actions could have such a strong effect on this drop of blood—what kind of relationship exists between them?” Su Che wondered in confusion.
Only then did Lao He understand the reason. He said gravely, “It certainly isn’t a harmonious relationship. Master, be careful with Tianyin. Under no circumstances let her know about the Witch Clan blood. I feel that if she finds out, it will definitely harm you.”
Su Che nodded silently; his thoughts matched Lao He’s exactly.
The sudden death of those thirty Yakshas shocked the entire Yaksha army. In panic, they scattered in all directions, no longer daring to block Tianyin’s path.
Although Yakshas were fierce, they were also intelligent creatures who feared death. They quickly realized that this was a human cultivator at the Golden Core stage, and attacking her would only lead to their own deaths.
Tianyin did not pursue those Yakshas because she still had to take care of the cultivators at the Qi Refining stage behind her. She turned around and ordered, “We’ll talk about it later.”
More than seventy cultivators followed her as they descended to the entrance of the cave.
“Grandmaster Tianyin has arrived!”
“Grandmaster Tianyin has come to save us!”
Cheers echoed inside the cave, and soon more than a dozen people rushed out.
“Grandmaster Tianyin!” They bowed respectfully.
Tianyin frowned slightly and asked gently, “Where are the others?”
A Cultivation Foundation-level disciple replied, “Reporting to Grandmaster, the others are still fighting inside. There are still many Yakshas and Earth Fiends there.”

Tianyin nodded slightly, finally understanding that they were in a dangerous situation under attack from both inside and outside. If she hadn’t come to rescue them, the fate of these disciples would be obvious.
So, Tianyin turned to Su Che and said softly, “Thank you.”
Without Su Che’s message, she would never have led her team here; instead, she would have followed another planned route for their training.
“It’s my duty,” Su Che replied, pretending to be flattered, though in truth, he already felt wary of Tianyin and wished to stay as far away from her as possible.
At this moment, Su Che was more concerned about the safety of his senior brother Yu Qing, so he bowed to one of the disciples and asked, “Excuse me, senior brother, is my senior brother Yu Qing from Tianxuan Sect here with you?”
“Yu Qing from Tianxuan Sect?” The man thought for a moment before nodding. “Yes, he’s still inside.”
Su Che thanked him and immediately said to Tianyin, “Ancestral Master Tianyin, I need to go inside to meet my senior brother.”
He said this because he predicted that Tianyin wouldn’t enter the mine cave—she would remain at the entrance to prevent those Yakshas, or even more powerful Asuras, from cutting off everyone’s escape route.
Tianyin nodded and said, “Tell them by the way not to engage in prolonged battles and to withdraw immediately! Say it’s my order.”
“Okay.”
Su Che agreed and dashed into the mine cave.
The entire mine was a vein of black-glowing ink crystal. To extract ink crystal, there was no need to dig deeper—just hollowing out the mountain’s interior was sufficient. This was because the underground world was already tens of thousands of feet deep, and in that world, all minerals were completely exposed.
Inside the mine tunnel, black crystals were exposed on the cave walls, emitting a faint glow—these were the raw ink crystals. Only after multiple refinements could they become true black-glowing ink crystals.
Su Che rushed along the tunnel. Although he encountered many forks, the sounds of intense fighting coming from ahead served as the best guide.
Soon, he reached the central area inside the mountain. The view suddenly cleared up, revealing a vast mining area over ten feet high.
At the center of the mining area stood a huge furnace, its blazing flames illuminating the entire cave like daylight.
Boom… Boom…
Two groups of people were clearly separated by over twenty feet, fighting fiercely with magic.

On the human cultivators’ side, there were only a little over twenty people, all at the Foundation Establishment stage. On the side of the earth demons, there were mainly over thirty Yakshas, along with a huge crowd of earth demon miners—no less than three hundred or so.

Su Che immediately spotted the back of Senior Brother Yu Qing, but instead of calling out anxiously, he silently flew over and landed quietly behind him.

All Foundation Establishment cultivators possess divine senses, so all the disciples of Wuji Gate noticed Su Che’s arrival. However, in the midst of the fierce battle, they didn’t have time to greet him.

“Junior Brother Su?”

Yu Qing turned around briefly. Though greatly surprised, he didn’t stop casting spells and asked through telepathy, “How did you end up in the Underground Demon Realm as well?”

“Just a coincidence,” Su Che replied with a smile through telepathy. “Senior Brother, wasn’t it said that the sect exchange missions aren’t dangerous? Why did you still follow the people from Wuji Gate to gain experience here?”

“What danger is this?” Yu Qing smiled proudly. “Don’t worry. Even if I were the only one left, I could still fight my way back to the surface. I’ve just never been to the Underground Demon Realm before, so I came to take a look.”

Such confidence?

Su Che was slightly stunned. Upon closer inspection, he was astonished to find that after just over three months apart, Senior Brother Yu Qing had already reached the mid-stage of Foundation Establishment.

“So fast?” Su Che thought to himself. “Generally, a year is considered the fastest time. He actually reached mid-stage in just three months…”

“Master, I can sense it…” Lao He immediately replied. “That mysterious force hidden within him has begun to release. I’ve always said that your Senior Brother Yu Qing is extraordinary. Who knows? It’s possible there’s even some primordial beast sealed inside him.”

Only then did Su Che remember that long ago, when he was still at the first level of Qi Cultivation, Lao He had said that there was an extremely powerful force hidden within Senior Brother Yu Qing.

Previously, this force had remained dormant. It seems that only after reaching Foundation Establishment could one unleash it.

Even so, Su Che genuinely felt happy for him and immediately sent a message: “Congratulations, Senior Brother. You’ve reached mid-stage of Foundation Establishment so quickly.”

“Quick?” With a whoosh, Yu Qing cast an ice spell and turned to smile. “If I don’t hurry, in a few days I’ll have to call you ‘Senior Brother’ too. You know I’m under a lot of pressure.”

Yu Qing had already realized that Su Che had also successfully reached Foundation Establishment, and his cultivation level was quite solid, even capable of advancing to mid-stage.

Su Che chuckled. “Senior Sister Linglong will always be my senior sister. The same goes for you, Senior Brother.”

Yu Qing smiled faintly and asked again, “Is it because you knew I was here that you came to help me?”
Su Che nodded in agreement but replied in a low voice, “If I had known you were just playing around, I would have gone back to my own affairs.”
Su Che had already realized that Senior Brother Yu Qing was in a very relaxed state—having shown only one-third of his strength while among the crowd, clearly in a leisurely mood.
“Since you’re here, come with me and make some money. I guarantee you won’t have come for nothing,” Yu Qing whispered. “In a bit, when they can’t hold on any longer and try to retreat, you must stay close to me, understand?”
Su Che guessed that Yu Qing must have discovered some advantage, which was why he mentioned making money. So he immediately reminded him, “Tianyin from Wuji Gate has also arrived and is guarding the entrance to the mine.”
“Tianyin…”
Only then did Yu Qing’s expression change slightly as he mused, “That’s a bit troublesome. Let me think…”
After a brief silence, he asked again, “Will you be able to get away in a bit?”
Su Che understood what he meant and nodded, “Yes.”
“Good. Then leave first and come back to find me. But make sure that Tianyin doesn’t follow us,” Yu Qing instructed.
“Okay.”
Su Che replied before shouting loudly, “Brothers, Grandmaster Tianyin has come to save you! Evacuate immediately and meet at the mine entrance.”
“Grandmaster Tianyin has arrived!”
The disciples of Wuji Gate perked up and shouted in unison, “Understood!”
“The message has been delivered. Brothers, I’m leaving now.”
Then, Su Che swallowed a Ground-Diving Pill in front of everyone and disappeared underground, pretending to evacuate first. In reality, he simply hid inside the ink-crystal ore veins to avoid their spiritual detection.
Su Che’s departure didn’t cause dissatisfaction among the Wuji Gate disciples. After all, everyone saw that he wasn’t one of their own but a disciple of Tianxuan Sect. Even though he had a mission to exchange with other sects, he wasn’t obligated to share life and death with Wuji Gate. The fact that he took such a risk to deliver the message was already quite honorable.
Thus, the disciples of Wuji Gate slowly retreated into the mine tunnels under the fierce bombardment of hundreds of earth demons.
Earlier, they had held their ground to avoid being trapped between the demons inside and outside, dying in the tunnels. But now that Grandmaster Tianyin had come to rescue them, there was no need to worry anymore.
Boom… boom… boom…

Amidst the clash of various spells, the disciples of the Wuji Sect slowly retreated into the passageway; hundreds of earth demons chased after them, screaming wildly. Before long, not a single figure was left in that vast cave. Once Lao He confirmed there was no one in the cave, Su Che emerged from underground. Without a word, he rushed to the furnace, took out the bronze gourd, and whispered toward the furnace mouth, “Collect!” Whoosh whoosh whoosh… Pale golden flames rushed in.
