Blue Lava
The spaceship flew straight to the basin where the Rotten Bone Mine was located and stopped above the deep pit at the mine entrance.
The four people disembarked from the spaceship and landed on the edge of the deep pit.
A male cultivator at the Foundation Establishment Middle Stage came to greet them.
"Greetings, Elder Chu; greetings, Young Master Chu; greetings to both seniors."
The male cultivator did not recognize Song Wen and Cui Yan, but he could sense the powerful aura of cultivation emanating from them.
Chu Lingyun asked the male cultivator, "Miao Cheng, what's the situation on the island?"
The male cultivator, known as 'Miao Cheng', replied respectfully.
"Elder Chu, everything left behind by the Tang Family has been taken over by my Miao Family. As per your instructions, Elder Chu, the mine has not been mined for the time being."
Miao Cheng's Miao Family, the Miao family, was clearly a Foundation Establishment Lineage that was dependent on Chu Lingyun, and they obeyed Chu Lingyun's orders without question.
By this time, Song Wen had roughly figured out the ins and outs of the matter.
Deep within the Rotten Bone Ore Vein, there must be some kind of treasure hidden, which is exactly what Chu Lingyun and Cui Yan need.
However, the Rotten Bone Mine belongs to Limitless Island and was originally mined by the Tang Family.
If news of the treasure leaks out and reaches Limitless Island, then Chu Lingyun and Cui Yan will have no chance to obtain it.
If the two want to secretly obtain the treasure behind Limitless Island's back, they must first seize control of the Rotten Bone Mine.
Therefore, after the appearance of the Netherfire Ants, Chu Lingyun quietly came to the mine, intending to use the Netherfire Ants to kill the Tang Family head without anyone knowing.
In this way, he could use the excuse that the Tang Family had failed in their duties to get another Lineage on Limitless Island to take charge of mining the Rotten Bone Mine.
He could then seize the opportunity to establish a Foundation Establishment Lineage that is dependent on him and gain control of the Rotten Bone Mine.
However, Song Wen's arrival to rescue Jing Kai disrupted his plans.
This forced him to take a risky gamble, resulting in the massacre of the entire Tang Family.
Song Wen originally thought that Chu Lingyun had personally carried out the massacre of the Tang Family. Now it seems that it was very likely Cui Yan who did it.
Therefore, when Limitless Island investigates, it will not suspect Chu Lingyun at all.
Having clarified these matters, Song Wen was somewhat worried about Jing Kai's side.
Aside from this person whose identity is unknown, Jing Kai is the only one who left Mist-Hidden Island alive. Regardless of whether he knows the inside story or not, Chu Lingyun will find a way to eliminate him.
If Jing Kai is captured and subjected to severe torture, he will be able to extract information that it was 'Extreme Yin' who saved him that night.
Upon thinking of this, Song Wen's heart tightened.
"Could it be that Chu Lingyun and Cui Yan already know that I rescued Jing Kai? Did they summon me here only to get rid of me? Was their earlier mention of the Gu-raising Alchemist a test?"
Song Wen was filled with doubt and unease, but his face remained calm despite the shock.
His gaze swept over Chu Lingyun and Cui Yan intentionally or unintentionally, but he didn't notice anything unusual on their faces.
"I'll lead some men into the mine to clear out the Netherfire Ants. You keep watch at the mine entrance and don't let anyone near it."
Chu Lingyun instructed Miao Cheng.
He never mentioned Song Wen and Cui Yan's true identities from beginning to end.
Then, he spoke to Chu Qian.
"You'll also stay outside the mine."
Having arranged everything, Chu Lingyun turned to look at Cui Yan, and after the latter nodded in acknowledgment, he jumped into the deep pit first.
Cui Yan followed closely behind.
Song Wen waited at the edge of the pit for a while until he received a telepathic message from Cui Yan.
"Extreme Yin, hurry up and follow!"
Song Wen had no choice but to jump into the deep pit.
The three arrived at the bottom of the deep pit, which connected to more than a dozen mine shafts that were several meters high.
Song Wen felt uneasy, but still pretended to be curious.
"Senior Cui, Fellow Daoist Chu, is there some treasure in this Rotten Bone Stone that would make you both come here?"
Cui Yan said coldly, "Knowing too much won't do you any good."
After saying that, he turned and entered one of the mine shafts.
"Let's go, Extreme Yin. Don't worry, you only need to assist me and Senior Cui, there will be no danger," Chu Lingyun said.
Song Wen nodded and walked into the mine that Cui Yan had entered.
The mine shafts are intricate and complex, like a maze.
After many twists and turns, the three of them arrived at the mine where Jing Kai had been trapped.
During their time there, the three encountered swarms of Netherfire Ants, but Cui Yan easily dealt with them all.
The ground where Cui Yan stood was covered with numerous holes, clearly left by Netherfire Ants building their nests.
He summoned a bone awl, which was about a foot long and triangular in shape.
Black, sinister Yin Qi swirled around the bone cone, and a cold, decaying aura permeated the air.
As Cui Yan infused his Law Power, the bone cone began to spin rapidly, and the Yin Qi formed a black vortex as the bone cone rotated.
The vortex emitted a sharp whistling sound, like the mournful wail of a ghost, sending chills down one's spine.
The bone spike suddenly pierced the ground beneath Cui Yan's feet.
The hard rock was instantly shredded, and the bone cone effortlessly drilled deep into the ground, leaving a hole about half a meter in size.
"Go!" Cui Yan shouted softly and jumped into the cave.
After traveling dozens of miles, a deep blue space came into view.
This is a huge underground cavern, tens of miles wide, filled with Lava.
But the Lava wasn't the usual bright red; instead, it was an eerie, ghostly blue.
Flames occasionally spewed from the Lava; the flames were a ghostly blue.
Although these yin flames did not reach the level of Spirit Flame, the cave was filled with a dense aura of yin and evil.
The sinister aura seemed to erode one's mind and spirit, making one feel extremely depressed and uncomfortable.
What is that?
Song Wen raised his hand and pointed to the depths of the cave.
There, a giant tortoise floats in the Lava.
Part of the giant tortoise's shell and head are visible, while the rest is hidden in the lava.
Even so, the exposed shell was the size of a house, like a reef standing in a sea of Lava.
The giant tortoise suddenly opened its massive mouth and inhaled sharply at the eerie fire spewing from the Lava.
The eerie blue flame instantly transformed into a slender blue streak, which fell into the giant tortoise's mouth.
"Don't worry, that's Yin Camel Tortoise. They feed on Yin Fire and are docile by nature. As long as you don't attack them, they won't attack you on their own," Cui Yan said.
Song Wen stared in disbelief at the giant tortoise that was spewing out yin fire.
Such a gigantic beast is surprisingly docile by nature.
This is a fourth-tier Demon Beast.
This is its home turf; if it goes berserk, Cui Yan will likely find it difficult to escape unscathed.
The Yin Camel Tortoise merely glanced at the appearance of Song Wen and his companions, seemingly knowing that they posed no threat to it, and then paid them no further attention.
Cui Yan took out a jade bottle containing the Hundred Flowers Detoxification Pill and gave three pills each to Song Wen and Chu Lingyun.
"One pill can protect you from the effects of the fire poison for one hour."
After saying this, Cui Yan and Chu Lingyun each swallowed a pill.
Song Wen was certain that the pill in his hand was one he had refined, so he swallowed it whole.
Led by Cui Yan, the three arrived at the edge of the cave, descended along the rock wall, and disappeared into the lava.
The rock walls, submerged in Lava, are jet black with a faint metallic sheen, appearing extremely hard.
Song Wen raised a Law Power shield, and the dark blue magma swept past his eyes.
As they went deeper, the Evil Qi emanating from the magma grew stronger.
To keep his Law Power shield intact, Song Wen's Law Power was depleted rapidly, and Chu Lingyun was in a similar situation. Only Cui Yan was completely unaware, as he consumed very little Law Power.
Fortunately, Cui Yan stopped abruptly after diving only a hundred or so feet.
On the rock in front of him was a crystal the size of a fingernail.
The crystal is deep purple and contains an extremely strong Yin Qi.
