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

"Your subordinate, Su Xinghe, greets the Inspector!" Su Xinghe was the first to react. He hurriedly stepped forward and saluted respectfully to Lin Han.

"Greetings, His Excellency the Inspector!" Immediately afterwards, Tailing Sect's leader Guangling, the Supreme Elder, Elder Qian and others also stepped forward and saluted Lin Han.

"No need to be so polite." Lin Han smiled faintly and waved his hand.

"Retreat!" The Black Wind Demon King was terrified. He knew he was in big trouble today and didn't dare to stay for even a moment. He immediately gave the order and wanted to flee with his men. However, Lin Han would never let him escape so easily.

"Want to leave? Have you asked me?" Lin Han sneered, and with a flash of his body, he blocked the way of the Black Wind Demon King.

"You...what do you want?" The Black Wind Demon King looked at Lin Han's cold eyes and felt a chill in his heart. He knew that he was in a desperate situation today.

"What?" Lin Han's lips curled up slightly, a hint of teasing flashed in his eyes, "What do you think, Lord Demon King? Didn't you say before that you would tear me into pieces? Why do you want to leave now?"

The Black Wind Demon King's face froze. Although he was terrified, as a demon king, he still had his dignity and pride. He took a deep breath, forcibly suppressing his fear, and said in a deep voice, "Lin Feiyu, I am the demon king of the demon clan. If you dare to kill me, it will inevitably cause a conflict between the demon clan and the Shenxuan Palace. You must think carefully!"

"Dare to threaten me?" Lin Han's expression hardened. He then reached out and instantly lifted the Black Wind Demon King up, as easily as a chicken. He looked at the Black Wind Demon King coldly, his voice icy and ruthless, "Do you think that a mere demon king like you can represent the entire demon race? That you can threaten the Divine Mysterious Palace? How ridiculous!"

“You…you…” The Black Wind Demon King was so overwhelmed by Lin Han’s aura that he was speechless for a moment. He was terrified, knowing that he had really hit a wall today.

"Quickly let go of the Demon King! Otherwise... the Demon King will not let you go!" Seeing this, the Black Wind Demon King's men shouted, trying to threaten Lin Han. However, to Lin Han, their voices sounded like the buzzing of ants, insignificant.

"Demon King? Humph, I, Lin Feiyu, have never been afraid of anyone!" Lin Han sneered and waved his hand. A powerful wave of air blew away all the demon clan's subordinates. They screamed in pain and fell to the ground, unable to get up again.

Seeing this, the Black Wind Demon King was even more terrified. He knew that he was truly doomed today. He struggled to raise his head and looked at Lin Han's cold face. A strong desire to survive surged in his heart.

"Lin Feiyu, I... I am willing to submit to you, become your subordinate, and serve you! I only ask you to spare my life!" The Black Wind Demon King finally lowered his proud head and begged for mercy from Lin Han.

However, Lin Han showed no mercy. He looked at the Black Wind Demon King coldly, his voice icy and heartless: "Submission? You think that a mere demon king like you is qualified to be my subordinate? How ridiculous!"

"Don't kill me! I can tell you a secret about our demon race!" The Black Wind Demon King shouted hurriedly. He knew that he had no other choice and could only hope that this secret could save his life.

Lin Han raised his eyebrows and looked at the Black Wind Demon King with a hint of surprise. He hadn't expected the Black Wind Demon King to reveal any valuable secrets at this critical moment of life and death. However, since he said so, Lin Han didn't mind listening.

"Oh? What secret? If it is really a valuable secret, maybe I can consider sparing your life." Lin Han said lightly.

"This secret is the most confidential of our demon clan, and only the high-level members of the demon clan know it. Please block the hearing of the people around here, and they must not know this secret." The Black Wind Demon King looked nervous, fearing that Lin Han would not agree to his request.

Lin Han nodded slightly and flicked his finger. An invisible wave spread out, temporarily blocking the hearing of everyone around him. This way, no one except him and the Black Wind Demon King could hear their conversation.

"Okay, you can speak now." Lin Han looked at the Black Wind Demon King and said lightly.

The Black Wind Demon King took a deep breath, as if he had made up his mind, and whispered, "We, the demon race, have actually been searching for a legendary holy place - the Demon God's ruins."

"The ruins of the Demon God?" Lin Han frowned. He had never heard of this name, but it sounded extraordinary.

"That's right, the ruins of the Demon God. According to the ancient books of our demon clan, it is the place of inheritance left by a supreme demon god of the demon clan. According to legend, that demon god possessed power beyond the heavens and the earth, and could even challenge the laws of nature. The ruins he left behind hide the most powerful secrets and powers of the demon clan." There was a hint of yearning and fanaticism in the voice of the Black Wind Demon King.

"Power beyond heaven and earth? Challenging Heaven's Way?" Lin Han was shocked. This sounded simply too astonishing. You know, in the world of immortal cultivation, those who could challenge Heaven's Way were all top-tier experts. And this demon god could actually challenge Heaven's Way. Just how powerful was he?

"Yes, that demon god is a legendary figure in the history of our demon race. The relics he left behind are of extraordinary significance to our demon race. Once we can obtain the inheritance and power therein, our demon race will surely rise and become one of the most powerful forces in the world of immortal cultivation." When the Black Wind Demon King said this, there was a crazy light flashing in his eyes.

Lin Han listened quietly, his heart churning with indescribable emotions. He hadn't imagined that the demon race held such a shocking secret. If these demon god ruins truly existed and truly concealed the demon race's most powerful secrets and powers, then if the demon race gained access to these powers, it would be a disaster for the entire human race.

"Why do you tell me this secret?" Lin Han looked at the Black Wind Demon King and asked lightly.

"I... I just want to stay alive." The Black Wind Demon King lowered his head, his voice trembling slightly. "I know that once this secret is leaked, I will surely die. However, if I can tell you this secret, perhaps you can spare my life."

"You're really good at calculating." Lin Han sneered, a hint of amusement flashing in his eyes. "However, your secret does interest me. But if you want to survive, this alone is not enough."

"Then...what else can I do?" The Black Wind Demon King asked anxiously. He had no other choice and could only hope that Lin Han would let him go.

Lin Han pondered for a moment, then said, "I can give you a chance. From now on, you will be my spy, monitoring the demon clan's every move for me. Especially regarding the news of the demon god ruins, if there is any movement, you must report to me immediately. If you can do this, I can consider sparing your life."
