Originally, in the consciousness of the two siblings, the Demon Lord was the master of the Black Mountain!

Everyone must surrender to him.

In this case, the barrier in Black Mountain is naturally owned by the demon master. If the other party wants people to go out, they can let people out, and if they want people to come in, they can let people in.

However, Jiang Chao's analysis completely subverted their previous understanding.

"This can also explain why when my great-grandfather's generation first came here, there were no demon lords in the mountains. Everyone was doing their own thing," Ji Cao said solemnly.

Later, the reason why this demon lord appeared was because the other party practiced silently and became extremely powerful, and finally ruled the entire Black Mountain!

Then the problem comes.

What kind of existence is this Black Mountain?

How did those people get in back then?

All of this is full of fog.

"If this is really the case, doesn't it mean that even the Demon Lord may not be able to get out?" Ji Shu's face turned pale.

This is undoubtedly extremely despairing for him.

If even a powerful being like the Demon Lord can't pass through the barrier, then how can they do it?

"It's hard to say now, but judging from this barrier, if you have to forcefully break through, even a monk in the pill formation stage will have no chance of breaking through." Jiang Chaodao.

He put it lightly.

In his opinion, let alone the pill formation stage, even a higher cultivation level may not be able to break this barrier.

Because this barrier is too mysterious.

"You can't even reach the realm of the pill formation stage?" The siblings were shocked.

This also made their hearts feel cold.

If you say this, wouldn't it be impossible for them to go out for the rest of their lives?

"It's impossible to break in forcefully, unless we find other ways." Jiang Chaodao.

"Other ways?" The siblings were startled.

"Since this barrier is a formation, there must be a way to control it. If we can find this method, we can naturally get out." Jiang Chao said.

"But where can I find this?" Ji Shu grimaced.

This demon lord has ruled Montenegro for so many years, and the other party must have looked for it a long time ago, so how could it be their turn.

"By the way, are there any special legends in the Black Mountains?" Jiang Chao asked the siblings.

"A more special legend?" Ji Shu scratched his head.

However, Ji Cao remembered something, "I heard my mother say before that my great-grandfather's generation used to go to the depths of the Black Mountains to explore together, trying to find out the secrets of the Black Mountains, but those who went in later basically died.

The disappearance disappeared, and then nothing happened. My grandpa Zeng also left a notebook, does this count? "

"Forget it, is that notebook still there?" Jiang Chao was delighted.

This Black Mountain is too mysterious. If you want to get out, it seems you have to solve the mystery of this Black Mountain.

"The ones that are still there are hidden in the storage room of our house." Ji Cao nodded.

Jiang Chao took his siblings and walked along the edge of the barrier for another two days and two nights. After careful observation, they returned to their residence.

Ji Cao took him to the storage room and dug out a dusty wooden box.

Opening it, there was indeed a booklet inside the box.

However, this notebook is not complete, but incomplete.

"There was a monster wave at that time. When my parents took us to escape, this notebook was bitten by a monster." Ji Cao explained.

This short sentence is enough to describe the thrilling feeling at that time.
