I curiously stared at the Monster King and asked, "Why?"

"With this question, one of you is a demon, the other is a demon. In our demon realm, you are considered to be the mainstay. In the future, you will definitely be able to provide unlimited help to the demon realm. How could I possibly do anything that would harm myself?"

I suddenly became angry, "Don't mention anything about the same origin as me. You and I are completely different paths. You are a demon, you will be a demon for the rest of your life, and I am a human for the rest of my life. Don't talk about distorting the truth, it's useless for me."

The Monster King lightly said, "This Demon King will not force you. The way out lies behind you. You can leave at any time, but since there are different paths, I will not tell you about the Tranquil Heart Grass."

Seeing that I still had more to say, Qing Qing shook her head towards me and whispered, "Forget it. Since the Monster King is unwilling to speak, there's no need for us to beg it. Let's go out of here first before thinking of a way out."

I glared fiercely at the Monster King before turning around to leave with Qing Qing.

Before long, the voice of the Demon King came from behind. "Kid, this Demon King's territory welcomes your arrival at any time. When you've thought it through, come find this Demon …"

"Little Tian, don't listen to the Fey King's nonsense, you are a human, it's just that there is an additional Evil Spirit Art inside your body, but as long as you can control it perfectly, not only can you use it, you can also use the power of the Art to help others."

I nodded in agreement. "You're right, the Art of Soul Awakening is only a power. It isn't evil in nature, as long as the one who uses it has justice in his heart."

Supporting the weak Qing Qing as they walked out of the cave, the Monster King did not play any tricks, nor did he send any subordinates to stop them. When we arrived outside the cave, it was already bright outside. The sun should be at around ten in the morning.

"Little Tian, don't be sad. It's not your fault that you can't find the Tranquil Heart Grass. Besides, without the help of the Tranquil Heart Grass, I can still use my own cultivation to dispel the demonic energy in my body."

Actually, the more understanding Qing Qing was, the more guilt I felt. I was the one who proposed to attack Thunderclap Mountain, but ended up empty-handed. Furthermore, I even threw Aunt Caiyun's life away.

Standing outside of the cave, the mountain breeze blew against my face. I suddenly thought of a person, it was the black-clothed uncle that I met in the palace. He had also lived in Thunderclap Mountain for ten years, so he couldn't possibly have heard of the Tranquil Heart Grass.

Thinking about this, I held onto Qing Qing's hand as we walked towards the palace. I said to her, "Follow me, I'll do everything I can to help you find the Tranquil Heart Grass, otherwise, I'll let Aunt Caiyun down."

Very quickly, we returned to the entrance of the palace once again. However, this time, there was still Qingqing, but Aunt Caiyun was missing.

I lightly knocked on the small door a few times and shouted, "Uncle Black, we are back. Please open the door."

Jiyaaa!

After I shouted, the small door opened from the inside. Uncle who was wrapped in black clothes said calmly, "Why did you come back? Weren't you looking for the Monster King's nest?" "Hmm, is this girl the Qingqing you're looking for?"

Qing Qing walked forward politely and said, "Uncle Black Cloak, I am Qing Qing."

"You guys are really annoying. Why didn't you leave right after settling your own matters and come back to my palace?" The man in black grumbled, but he pushed open the door and let us in.

Uncle Heian, who was standing at the side, watched Qing Qing and I enter. After waiting for a while, he closed the door and puzzledly asked, "That's not right, where's the girl who went out with you last night? Why didn't she come back? Could it be that the Monster King …"

"Damned Demon King, one day I'll come back and kill it myself, and avenge Aunt Caiyun." I secretly made a vow and said resolutely.

"I've fought with the Monster King for dozens of years, and I've used every method at my disposal, but I still haven't been able to kill it. Its defensive power is shockingly strong, how could you kids kill it?"

"Hmph, it's not that its defense is strong, but that it devoured tens of thousands of souls and had tens of thousands of lives. Otherwise …"

"Wait, what did you say just now? The Demon King has over ten thousand lives … " It was unknown whether he was happy or angry, but after a while, he suddenly came to a realization and said, "Right, it must be like this. I told you that there is no demon with such strong defense in this world."

"Kid, how did you find this?"

I explained in detail what Aunt Caiyun was up to, and added in the end, "The Monster King only has over ten thousand lives. Apart from that, it doesn't have much attack power."

"Weird, too weird." The black-clothed man paced back and forth, his mouth constantly saying something strange.

Looking at how he kept walking around, I curiously asked, "Uncle Black, what's so strange about that?"

Even if it was like you said, the Monster King's defense isn't the reason, but rather it has over ten thousand lives, but that isn't the key, the Monster King's attack is also very strong, even I only have a slight advantage, but you said that it doesn't have any attack power, isn't that strange enough?

Qing Qing and I looked at each other and recalled the process of dealing with the Monster King in the cave. It was really at a disadvantage of being beaten passively and didn't counterattack. Could it be that the Monster King didn't want to hurt itself?

This was impossible, especially in the face of Aunt Caiyun's desperate moves. The Monster King did not retaliate at all. Could it be that he did not truly want his aunt to die?

"Uncle Black Cloak, ever since I've seen the Monster King, it has indeed been passively getting beaten up the entire time without even being able to fight back."

Uncle Black also couldn't figure it out no matter how much he thought about it. He looked at my body once before locking his gaze on Qing Qing. He suddenly let out a loud laugh and said, "I understand. So that's how it is."

"Please speak your mind, Uncle Black."

"This girl has a strong demonic aura and you also have an extremely dark and evil yin aura. I'm afraid that the Monster King has treated you as its own and thus did not secretly kill you."

I will think of the Demon King's final suggestion he made to me, he has indeed treated us as his own origin. From the looks of it, Demon Kings can indeed be called kings, and at times, it would be better for him to suffer than to harm his own origin.

Hmph, I was just thinking about it, but I don't agree with how great the Monster King's method is. In fact, its thoughts are very obvious, the reason it doesn't kill Qing Qing and I is because it wants to get the demonic nature and yin aura from us.

Suddenly, the black-clothed man pointed at Qing Qing and me as he coldly said, "Hurry up and leave. You're not allowed to take even half a step into Thunderclap Mountain."
