At this time, Liu Zhengyang finally came to the foot of the mountain.

Although the plants are dense and the animals are equally dense, there is no trace of human presence here.

Logically speaking, the terrain at the foot of the mountain is flat and there are enough water sources. It already has the rigid conditions for the existence of a village, but unfortunately, there is no such thing here.

The Nightingale Demon Emperor suddenly appeared at the mouth of the valley opposite Liu Zhengyang.

"Looks like we've all been deceived!"

The Nightingale Demon Emperor didn't seem to be anxious at all, and looked at Liu Zhengyang with a half-smile.

Liu Zhengyang looked up at it and said, "Are you going to fight?"

"Fighting? It's all down to this situation, is there any point in fighting?"

Liu Zhengyang raised his eyebrows: "So you know where this place is?"

"Those people are despicable, but they didn't lie. This is indeed the foundation of the seal of the demon world, but it is not easy to find the foundation in this cave."

A smile flashed in the Nightingale Demon Emperor's eyes: "Do you know why I say that? Because this little cave is called a purgatory cave!"

"Purgatory cave?"

"right!"

The Nightingale Demon Emperor nodded: "This used to be the place where prisoners were held, and the passage of time is different from outside. What you see now is just the most peaceful scene."

"However, according to my calculations, this kind of peace will not last for long, maybe it will change dramatically in a while?"

"Oh, by the way, do you know why I know this?"

Liu Zhengyang glanced at it: "Why?"

"Because my grandfather was imprisoned here!"

The corner of the Nightingale Demon Emperor's mouth revealed a stern smile: "And this was once the treasure of your deadwood sect!"

"what?"

Liu Zhengyang's pupils shrank suddenly, never expecting such a thing to happen!

"What? Are you surprised?"

The Nightingale Demon Emperor shrugged his shoulders: "Actually, when I walked out of the gate of the demon world, I already had a hunch, but it's safe to do so, I can see with my own eyes that the inheritors of the dead wood sect are also full in purgatory. To suffer, isn't this also a very interesting thing?"

"I'll find my way out!"

Liu Zhengyang glanced at the Nightingale Demon Emperor.

"The way out? Hahaha! Then I'll be happy! As long as you go out, you must break this little hole."

The Nightingale Demon Emperor raised his head and laughed loudly, then stared at Liu Zhengyang with scarlet eyes: "As long as you break the Xiaodongtian, the foundation of the seal of the demon world will also be destroyed!"

"How? Will you go back then?"

Nightingale laughed wildly.

If it is the beginning, Liu Zhengyang may be entangled.

But now, he shook his head.

"I want to go back, Tiannan Province still has people I want to protect, and people I want to love, and as long as your monsters dare to set foot on the land of Tiannan Province, I will recklessly tear you apart!"

Liu Zhengyang looked solemn: "As for the others, do I still have the obligation to protect them?"

"I am not a defender of the Tao, and I will not be kidnapped by the so-called morality. I only want to protect those who need my protection. As for the others, that is the incompetence of the Yan Kingdom, not me!"

Nightingale was stunned, then looked up and down at Liu Zhengyang.

"Tsk tsk, I'm really getting more and more curious about you now!"

After Nightingale finished speaking, a black light suddenly appeared, heading straight for Liu Zhengyang.

Liu Zhengyang frowned slightly after dodging: "Is it still so despicable for a dignified and powerful demon emperor?"
