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

Although the plants are dense and the animals are also dense, there are no traces of human existence.

Logically speaking, the terrain at the foot of the mountain is flat and there are enough water sources. It already has the hard 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.

"It looks like we have all been cheated!"

The Nightingale Demon Emperor didn't seem to be eager at all, looking at Liu Zhengyang with a smile.

Liu Zhengyang looked up at it, "Do you want to fight?"

"Fighting? They are all reduced to this situation, is there a point in fighting?"

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

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

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

"Purgatory Cave Sky?"

"right!"

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

"But according to my calculations, this peace will not last long, maybe it will change drastically 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!"

A sorrowful smile appeared at the corner of the Nightingale Demon King's mouth: "And this was once the treasure of your Withered Wood School!"

"what?"

Liu Zhengyang's pupils shrank suddenly, never expected that such a thing would happen!

"What? Surprised?"

The Nightingale Demon Emperor shrugged: "Actually, I had a hunch when I walked out of the gate of the demon world, but I will be at ease when I come. I can see with my own eyes that the inheritors of the Withered Wood Sect are also full of purgatory. Suffering, isn't this also a very interesting thing?"

"I will find a way out!"

Liu Zhengyang glanced at the Nightingale Demon Emperor.

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

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

"How is it? Will you go back then?"

Nightingale laughed presumptuously.

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

But now, he shook his head.

"I want to go back, there are still people I want to protect in Tiannan Province, and people I want to love, and as long as your demons dare to set foot on the land of Tiannan Province, I will tear you apart completely at all costs!"

Liu Zhengyang looked solemnly: "As for other people, do I still have the obligation to protect?"

"I am not a defender, nor will I be kidnapped by the so-called morality. I only want to protect those who need my protection. As for others, that is Yan Guo's incompetence, not me!"

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

"Tsk tusk, I am really more and more curious about you now!"

After Nightingale finished speaking, she suddenly urged a black light to come straight to Liu Zhengyang.

After Liu Zhengyang dodged, his brows frowned slightly: "Is it so despicable to be a powerful demon king?"
