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

Afterwards, Meng Chuan learned about the power structure of the Divine Realm Continent.

This continent is vast and boundless, with countless forces, large and small.

Although the Hall of Myriad Laws is the overlord of the coastal region, it can only be considered a powerful force in the entire Divine Realm Continent, far from being invincible.

Deep within the continent lie even more ancient sects, more powerful clans, and more mysterious forbidden lands…

Those places are the true core stage of the Divine Realm Continent.

Meng Chuan silently memorized this information and did not linger in Linhai City.

He still has an appointment.

More than 170 years is neither a long nor a short time.

He traveled and explored as he went, passing through many cities, mountains, and hidden places.

Sometimes he would stop and retreat to a mountain for months to digest the insights gained from the Time-Space Mystery Stone.

Sometimes he would go into a town to gather information and listen for any rumors about Houtu.

Unfortunately—

There was still no news of Houtu.

It was as if she didn't exist in this world.

Although Meng Chuan felt somewhat disappointed, he wasn't too anxious.

He knew that Houtu must be somewhere in the divine realm.

As long as she is alive, they will meet again someday.

Moreover, her name is still on the Extraterrestrial Demon Ranking, which means she is still alive and well.

More than 170 years have passed in a flash.

When Meng Chuan stood in Cangqing Town at the foot of the Cangqing Mountains, there were less than three months left until the agreed time.

Cangqing Town is small, with only a few hundred households.

However, because it is backed by the Azure Mountain Range, cultivators who go into the mountains to hunt or gather herbs often stop here, and there are a few inns and blacksmith shops in the town.

Meng Chuan found a clean inn in town and stayed there, waiting for Gu Changyuan to arrive.

……

Three months later.

Outside Cangqing Town, a streak of azure light descended from the sky and landed at the town entrance.

The newcomer was dressed in a green robe and had a handsome face; it was none other than Gu Changyuan.

As soon as he arrived at the town entrance, he sensed Meng Chuan's presence, a smile appearing on his lips as he walked towards the inn.

"Fellow Daoist Meng, I've kept you waiting."

Gu Changyuan pushed open Meng Chuan's door and greeted him with a smile and a cupped-hand salute.

Meng Chuan got out of bed and returned the greeting: "Fellow Daoist Gu has arrived on time."

"How could I dare to be late for the agreed time?"

Gu Changyuan entered the room, sat down at the table, poured himself a cup of tea, and said, "Fellow Daoist Meng, how have things been these past hundred years?"

"It went fairly smoothly."

Meng Chuan didn't elaborate on the Time-Space Stone, but simply asked, "As for Fellow Daoist Gu, how are your preparations going?"

Everything is ready.

Gu Changyuan took out a jade slip from his pocket and placed it on the table. "This is the survey data left by my senior brother. I have checked it repeatedly over the years and confirmed that it is correct."

"The next period of weakening of the formation will be in seven days."

"At that time, we will only have seven days to enter the ruins. After seven days, the formation will be restored, and we will be trapped inside until the next three hundred years."

Meng Chuan nodded, picked up the jade slip, and probed it with his divine sense, examining it carefully.

The jade slip contained a detailed topographical map of the outer perimeter of the ruins deep within the Azure Mountains, as well as the operational rules of the formation.

The locations of traps and safe passages are clearly marked.

"no problem."

Meng Chuan put down the jade slip. "When do we depart?"

"First thing tomorrow morning."

Gu Changyuan stood up, walked to the window, and looked at the outline of the distant Azure Mountain Range. "Let's get into the mountains as soon as possible and familiarize ourselves with the terrain."

"it is good."

Meng Chuan also stood up, his gaze fixed on the rolling mountain range.

Deep within the Azure Mountains lies an ancient ruin that has slumbered for countless millennia—

The mystery of this place is finally about to be unveiled.

……

The next morning, as dawn broke.

Meng Chuan and Gu Changyuan met outside Cangqing Town. Without exchanging any words, the two figures simultaneously took to the air and flew towards the depths of the Cangqing Mountains.

The morning mist had not yet dissipated, lingering among the mountains and forests like a thin veil covering the rolling hills.

The two flew very low, almost skimming the treetops.

Gu Changyuan led the way, his agile figure clearly indicating that he was extremely familiar with the terrain of the area.

"The Azure Mountain Range stretches for millions of miles from east to west and is extremely deep. The deeper you go, the stronger the monsters become and the more poisonous miasma there is."

As Gu Changyuan flew, he explained to Meng Chuan, "Our destination is a hidden canyon deep in the mountains. It is protected by natural formations. If my senior brother hadn't accidentally wandered into that area back then, probably no one would have discovered its anomaly to this day."

Meng Chuan nodded without speaking, but his divine sense had already spread out, taking in the surrounding area of ​​dozens of miles.

In the mountains and forests, the aura of demonic beasts could be seen from time to time. Most of them were only at the level of saints or below. After sensing the aura of the two, they all avoided each other and dared not get close.

After flying for about half a day, the terrain began to become rugged.

The once gentle mountain slopes suddenly become steep, with towering peaks rising abruptly from the ground, shrouded in mist, and deep, bottomless canyons crisscrossing the landscape like jagged scars etched into the earth.

Gu Changyuan stopped in front of a steep mountain peak and landed on a protruding rock.

Meng Chuan followed closely behind and landed beside him.

"arrive?"

Meng Chuan looked around but did not see any obvious entrance to the ruins.

All that could be seen were jagged rocks, dense vines, and howling mountain winds; everything seemed utterly ordinary.

"It's just ahead."

Gu Changyuan pointed to a seemingly ordinary mountain wall in the distance. "That natural formation is extremely sophisticated, completely concealing the entrance to the canyon. Unless you know the exact location, even if you fly over it, you won't notice anything unusual."

He took out a palm-sized compass from his pocket. The compass was covered with densely packed runes, and a pointer in the center was slowly turning.

"This is a formation-breaking plate left behind by my senior brother, specially crafted for this natural formation. Once the formation weakens, it will guide us to the entrance."

Meng Chuan glanced at the compass but didn't ask any further questions.

The two sat cross-legged on the rock, waiting for their chance.

Time passed day by day.

On the evening of the seventh day, the afterglow of the setting sun dyed the entire mountain range golden.

Just as the sun was about to set, the compass in Gu Changyuan's hand suddenly emitted a soft hum.

The pointer suddenly spun half a circle, then steadily pointed to the mountain wall ahead.

"They're here!"

Gu Changyuan abruptly stood up, a glint of shrewdness flashing in his eyes. "The formation is already weakening!"

Meng Chuan also stood up, his gaze falling on the seemingly ordinary mountain wall.

In his perception, the originally unified fluctuations of laws on that mountain wall did indeed show a slight loosening at this moment.

It was like a tightly closed door slowly cracking open.

"Walk!"

Holding a compass, Gu Changyuan took the lead and flew towards the mountain wall.

Meng Chuan followed closely behind.

The two of them crashed into the hard stone wall, one after the other.

The anticipated collision did not occur.

The moment you touch the mountain wall, the scene before you suddenly changes.

The stone wall seemed to transform into a curtain of water, and the two figures passed through it without any hindrance.

The moment he passed through the water curtain, Meng Chuan felt a sudden change in the surrounding laws.

It felt like stepping from one world into another...

The scene before me was completely different from the outside!
