My classmates chose martial arts and fantasy, but I chose the prehistoric world.

Just as Meng Chuan and his two companions were about to speed up and approach the cloud-top island, Meng Chuan suddenly stopped.

He noticed a detail—

When the native inhabitants of the divine realm who flew out from the direction of the island got close to the three of them, their gazes would always sweep over them with a strange expression.

That expression wasn't hostile, nor curious, but rather...

There was a subtle sense of estrangement, as if I had seen something unclean.

In Meng Chuan's mind, the words spoken by the dragon three thousand years ago instantly came to mind: "You have the aura of a forbidden land on you."

He didn't pay much attention at the time, thinking it was just something the dragon said casually.

But now it seems that this statement may have a deeper meaning.

"Wait a minute."

Meng Chuan suddenly spoke, calling out to Yan Qing and Tapa, who were about to continue on their way.

The two stopped and looked at him with a puzzled expression.

"Teacher, what's wrong?"

Yan Qing asked.

Meng Chuan did not answer immediately, but instead carefully observed the natives of the divine realm who passed by them once more.

He discovered that most of the strange-looking natives were those who were close to them and could clearly sense their presence.

Those indigenous people who were further away or only caught a fleeting glimpse did not show any unusual reaction.

"We probably still carry the so-called 'forbidden zone aura' on us."

Meng Chuan said in a deep voice, "That dragon's words weren't just casual remarks. The strange looks those natives of the Divine Realm are giving us are very likely because of this."

Upon hearing this, Yan Qing and Tapa's expressions both changed.

Tapa's three purple eyes flickered a few times, and he said in a hoarse voice, "Fellow Daoist Meng Chuan is right. I noticed it just now too; a few natives passing by did look at us strangely. I just didn't think of it that way at the time."

A hint of apprehension flashed in Meng Chuan's eyes: "In my opinion, we should deal with the forbidden zone aura on our bodies first, and then go to that island."

Yan Qing and Tapa exchanged a glance and both agreed that Meng Chuan's words made sense, so they nodded.

The three changed direction and flew towards the sparsely populated sea area.

They found a secluded spot among the rocks, landed on a large rock, and began to study how to remove the forbidden aura from their bodies.

However, problems soon arose—

They had no idea what the so-called "forbidden zone aura" was.

Meng Chuan tried to use his divine sense to examine his entire body, scanning it carefully several times, but he did not find any abnormal residual aura.

Yan Qing and Tapa were in the same boat; no matter how they searched, they couldn't find any so-called "forbidden zone aura".

"Could it be that our way of perceiving is wrong?"

Yan Qing frowned and said, "Perhaps only the natives of the Divine Realm can sense this aura?"

Tapa pondered for a moment and said, "That's possible. After all, we are outsiders, so it's normal that we are not as good as the natives in some aspects."

Meng Chuan was silent for a moment, then said, "Since we can't find it ourselves, let's find someone who can help us find it."

After he finished speaking, he turned to look at the vast sea, his gaze fixed on a certain direction in the deep sea.

"Wait for me here."

Meng Chuan left a sentence, then moved and transformed into a streak of light, rushing directly into the sea.

Yan Qing and Tapa looked at each other, wondering what Meng Chuan was going to do, but they obediently stayed on the reef to wait.

About half an hour later, the sea suddenly exploded, and Meng Chuan's figure soared into the sky, carrying a huge creature in his hand—a massive deep-sea monster.

The monster resembled a crab magnified countless times, its entire body covered in a dark brown shell, its eight legs flailing wildly in the air, and it emitted strange squeaking sounds.

Its aura is roughly equivalent to the level of a fusion of three laws.

Meng Chuan threw the monster onto the reef. The monster was so frightened that it curled up into a ball, its eight legs tightly hugging its shell, trembling.

"Spare me...spare me, Your Excellency!"

The monster begged for mercy in terror.

Meng Chuan crouched down, looked at the monster, and said calmly, "Don't be afraid. I'll ask you a few questions. If you answer honestly, I'll let you go."

The demon beast nodded hurriedly: "Please ask, sir! I will answer to the best of my knowledge!"

Meng Chuan asked, "Tell me, what is 'Forbidden Zone Aura'?"

Upon hearing this, the monster trembled violently, its eight legs clinging even tighter, its voice tinged with fear: "M-Why...why is the master asking this?"

Meng Chuan frowned: "Just answer."

Sensing the oppressive aura emanating from Meng Chuan, the demonic beast dared not utter another word and hurriedly said, "The aura of the forbidden land... it's the unique aura of those extraterrestrial demons trapped in the 'forbidden land'!"

"It is said that those were marks deliberately left on them by the Great Dao of the Divine Realm when it trapped them in the forbidden area, in order to distinguish them from the extraterrestrial demons and the native creatures of the Divine Realm!"

Upon hearing this, Meng Chuan understood.

Sure enough.

He continued, "Then how can we eliminate this forbidden area's aura?"

The demonic beast cautiously said, "I heard that one of our clansmen imprisoned several extraterrestrial demons... and then discovered that the forbidden aura on the extraterrestrial demons gradually fades over time."

"It speculates that after the extraterrestrial demons leave the forbidden area, their aura will fade to the point of being undetectable in about five thousand years."

After listening to what the other person said, Meng Chuan nodded thoughtfully.

Around five thousand years ago...

It has only been three thousand years since he, Yan Qing, and Tapa left the forbidden area.

According to the demonic beast, the aura of the forbidden area on their bodies should have faded considerably, but it hasn't completely disappeared.

This explains why the indigenous people of the nearby divine realm looked at them with strange eyes—

Because they could still faintly sense that lingering aura.
