Starting with the Immortal Cultivation System, what can you use to fight me?

Lin Han walked leisurely to the two ghosts, his eyes fell on Yan, and he asked calmly: "Several young people came here to explore before. It was you who planted the 'yin consciousness mark' on their bodies, right?"

"Could it be that you are the one who broke my 'Yin Consciousness Brand'!" Yan stared at Lin Han intently, as if he wanted to eat him alive.

Lin Han raised a faint smile and nodded noncommittally: "Yes, it's me. Why, are you surprised?"

A hint of resentment flashed in Yan's eyes, but he still asked unwillingly, "How did you do it? My 'Yin Consciousness Brand' can only be broken by me or a ghost more powerful than me. You are not a ghost, how could you possibly break it?"

"Everything in this world is interdependent and mutually exclusive. Even the most sophisticated magic has its flaws." Lin Han said calmly, then changed the subject, "Tell me, why did you place the 'Yin Consciousness Brand' on them? What is your intention?"

Nightmare, with the air of a dead pig fearless of boiling water, snorted coldly: "Humph, do you think I will tell you? Stop dreaming!"

"You're still so stubborn?" Lin Han didn't get annoyed. He just smiled slightly, quietly extended his right hand, put his index finger and middle finger together, and waved it lightly. A subtle light that contained powerful spiritual power instantly penetrated into Yan's body.

Nightmare's body trembled violently, and a look of pain appeared on his face, as if thousands of ants were gnawing at his soul. "Ah! What...what did you do to me?!" he roared.

Lin Han curled his lips into a cold smile and said slowly, "It's just a little trick to let you experience what true pain is. Now, you still have a chance to choose whether to speak the truth or continue to endure this pain."

&34;No... Impossible!!!&34;

Nightmare's face was filled with twisted pain, but he still tried to remain tough. "I...I won't tell you! Don't even think about getting a single word out of me!"

"Haha... Don't worry, I believe you will answer truthfully." Lin Han had a calm face and looked confident.

"Who the hell is this guy? He can actually use such a terrifying soul-crushing technique on Nightmare. Only the master can use such a method! How could this kid be possible?" The ghost was terrified and felt a deep fear of Lin Han in his heart.

&34;Ahhhhhhh…&34;

The Nightmare wailed incessantly, the agony deep within its soul nearly causing it to collapse. Finally, amidst the endless torment, its will was completely crushed.

"I'll tell you! I'll tell you!" Yan finally couldn't bear it anymore and chose to compromise.

Lin Han looked at Yan with a half-smile and said, "Look at you, why didn't you just say it earlier? Why are you asking for trouble?"

"Go ahead and tell me your purpose. If you dare to lie to me, I guarantee you will suffer a hundred times or a thousand times more than before. Think carefully about it."

After saying that, Lin Han raised his finger slightly, as if to imply that Yan could inflict that unbearable pain on him again at any time.

A trace of fear flashed across Yan's eyes, and he immediately lowered his head. His voice trembled as he began to narrate, "The reason I placed the 'Yin Consciousness Mark' on them was to attract more people to come here and explore the secrets. From among them, I could select those who met my master's needs and present them to him, hoping that he would grant me even greater power."

When Yan said this, his voice trembled even more, and he was obviously very afraid of the so-called "master".

"What does your master do with these people who meet the requirements?" Lin Han raised his eyebrows and continued to ask.

&34;This...this...&34;

Nightmare's face was apprehensive, as if the next words only frightened it even more. But under Lin Han's all-seeing gaze, it finally spoke tremblingly, "Master... he's practicing a forbidden technique that requires the souls and life force of many living people as sacrifices. Those chosen will eventually be sacrificed by the master to help him break through his bottleneck."

Upon hearing this, Lin Han's eyes instantly became fierce. "Forbidden technique? Humph, you really dare to practice such evil methods at the cost of innocent lives. Tell me, who is your master? Where is he now?"

Yan's body trembled again, and deep fear and hesitation flashed in his eyes: "Master, he... I can't tell you his identity. If I tell you, I will be scared to death!"

Lin Han frowned slightly, his voice low and firm: "Do you think you can save your life by not telling me? Don't forget, all your pain now is under my control. If you don't tell me in time, your fate will only be worse."

Nightmare's body trembled violently with fear. He knew full well that Lin Han's words were true. He didn't want to experience the pain of having his soul torn apart again. After a fierce inner struggle, he finally spoke, his voice tinged with determination: "Master... he's in the Yuantian Martial Realm—the Netherworld Ghost Realm. Everyone calls him the 'Netherworld Ghost Saint'!"

As soon as he finished speaking, Nightmare's ghostly body suddenly trembled violently, and then began to dissipate, as if forcibly erased by some force. "No... Don't... I won't give up...!" Nightmare's voice gradually weakened, and finally faded into nothingness.

This sudden change of events left Lin Han slightly stunned. He hadn't expected Nightmare to be retaliated immediately after revealing the truth. But on second thought, this made sense. After all, the "Ghost Saint of the Netherworld" behind it was no pushover and would definitely have ways to prevent his subordinates from betraying him.

"Please, please spare me! I don't want to end up like Nightmare." The ghost beside him was so frightened that he immediately knelt on the ground, kowtowed and begged for mercy.

Lin Han glanced at Gui Mei with a cold gaze and said, "Then it depends on whether you are valuable. Tell me everything you know about the 'Netherworld Ghost Saint' and the Netherworld Ghost Realm."

"But...if I tell it, I will be reduced to ashes like the nightmare!" said the ghost in fear.

Lin Han pondered for a moment, then flicked his finger. A gentle light enveloped the ghost, forming a transparent shield. "Within this shield, your soul will be protected by me. Even your master will be unable to sense your betrayal, let alone retaliate against you."

The ghost felt the strange power that suddenly appeared in his body, and a hint of surprise and disbelief flashed in his eyes. "Really...really?"

"I don't have the patience to talk nonsense with you. You have two choices now. Either tell me everything I want to know, or I will send you on your way now." Lin Han's voice was calm but with unquestionable majesty.

Feeling the powerful aura emanating from Lin Han, the last shred of hope in Gui Mei's heart was shattered. "I say, I say! The Netherworld Ghost Saint is the supreme ruler of our Netherworld Ghost Realm. The forbidden techniques he practices do require a large number of human souls and vitality.

Every once in a while, he would send his men to the human world in search of suitable sacrifices. I, originally just an ordinary ghost from the Netherworld, was discovered by chance by the Netherworld Ghost Saint, who granted me a certain amount of power, making me his supervisory messenger in the secular world, responsible for ensuring that his men were diligently searching for sacrifices for him.
