This is the edge of the barrier.

Although it looks like a stone forest, it is just an illusion caused by the barrier.

Once someone walks into the stone forest, they will be lost in it and disappear forever.

Over the years, countless people in Black Mountain have stepped into the stone forest and tried to break through the barrier and leave, but they all ended in failure.

The result of failure is death.

What is particularly terrifying is that people outside can clearly see the process of people entering the stone forest getting lost and then being wiped out.

Naturally, Jiang Chao would not act rashly.

They stopped here temporarily, and Jiang Chao walked along the edge of the stone forest to observe the surrounding terrain pattern.

In the way of arithmetic, the best solution is naturally to use arithmetic.

However, after several investigations, Jiang Chao realized that the mystery and depth of this barrier was completely beyond his imagination.

"When did this barrier appear?" Jiang Chao asked the siblings.

"I don't know." Ji Shu shook his head.

Ji Cao frowned slightly and said, "It seems that because of the existence of Black Mountain, this barrier exists?"

"Then your parents also grew up in Montenegro?" Jiang Chao asked.

"Yes, my parents were born in Montenegro, but not my great-grandfather's generation." Ji Cao said.

Jiang Chao's heart skipped a beat, "Then how did they get in?"

Regarding this issue, the siblings are not very clear either.

"I heard from my mother that in my great-grandfather's generation, many people found themselves in Montenegro when they woke up, and no one knew what happened," Ji Cao said.

Jiang Chao thought thoughtfully, "So, the people in Black Mountain are actually from the outside world?"

"It doesn't seem to be entirely true. When my great-grandfather and his group came, there were already residents in the Black Mountains, and they had been living there for a long time." Ji Cao said.

"Didn't Brother Xiao Jiang come in because of the explosion? Could he be like them?" Ji Shu asked.

Ji Cao shook his head, "Brother Xiao Jiang's situation is quite different from theirs."

Jiang Chao also agreed with her statement.

The reason why I was able to come in was entirely due to the distortion of time and space when I traveled through the barrier between heaven and earth.

This shouldn't be the case for other people.

It looks more like it was thrown in by someone.

So what exactly happened that year?

"Then where did this demon lord come from?" Jiang Chao thought for a moment and asked.

"When my great-grandfather and the others came in, there was no such demon cave. About a few decades later, this demon lord suddenly appeared, built the demon cave, and became the master of Black Mountain. Anyone who dared to resist would be conquered by him.

Brutally tortured and killed!"

When the siblings talked about this, they were both filled with indignation.

"If you put it this way, this barrier may not necessarily be related to the Demon Lord?" Jiang Chao thought for a moment and said.

The siblings were stunned for a moment.

All along, they had actually thought that this barrier should be closely related to the demon lord, or even created by the demon lord. However, when Jiang Chao said this, they felt that this was not necessarily the case.

"Has the Demon Lord ever left Montenegro?" Jiang Chao asked.

The siblings shook their heads.

They didn't know whether the Demon Lord had ever gone out, but at least they hadn't heard of it.

Although there have been rumors in Montenegro that one can only leave Montenegro with the permission of the Demon Lord, but this is just a rumor and no one has really confirmed it.

"So there is a possibility that this demon lord is actually just a prisoner imprisoned in Black Mountain." Jiang Chao said.

The two siblings looked at each other in shock.
