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

In response to her brother's question, Meng Xiaoyu replied telepathically, "Brother, this is a long story... Shall we go back and talk about it?"

Meng Chuan nodded.

"Let's go home."

As soon as they finished speaking, the two disappeared from everyone's sight as if they had teleported!

At this moment, the discussions on the playground erupted like a boiling pot.

"Two Grand Luo Immortals from one family! The Meng family is defying the heavens!"

"I just filmed a video! It'll definitely go viral online!"

……

A few minutes later, the trending topics list was unsurprisingly dominated!

All of the top ten are related to Meng Xiaoyu:

#Meng Xiaoyu, a late-stage Grand Luo Golden Immortal#

#Mengchuan's Sister Returns from the Primordial Era#

#The Strongest Family on Earth: The Meng Family#

#Yuncheng No.2 Middle School#

#Golden Teleportation Beam#

#The value of the prehistoric world continues to rise#

……

The comment section exploded:

"Holy crap! Holy crap! Holy crap! Late-stage Grand Luo Immortal?! Two years ago, when Meng Chuan first came back, she was just an ordinary first-year high school student, right?!"

"Two top-tier immortals in one family! What kind of extraordinary family is this?!"

"Meng Chuan is in the late stage of the Great Luo realm, and his sister is also in the late stage of the Great Luo realm... Is the Meng family going to rule the Blue Star?"

"Is it too late for me to acknowledge Meng Chuan as my godfather?"

"It's too late, the queue stretches all the way to the Milky Way."

Meng Xiaoyu: I went on a trip to the prehistoric world and came back as a late-stage Great Luo Immortal. What about you guys?

That's heartbreaking!

……

Meng Family Manor.

Meng Xiaoyu sat on the sofa in the living room, holding a glass of juice, and began to tell Meng Chuan about what had happened after she entered the prehistoric world.

"As soon as I entered the primordial world, I crushed the bone fragment you gave me, brother..."

"Then, I was targeted by a demon of the Great Luo level and almost died!"

"Luckily, Sister Houtu appeared in time and killed her!"

"If I had been even a little slower in crushing the bone fragments, it would probably have been too late..."

Meng Xiaoyu still felt lingering fear when she spoke of this.

Even Meng Chuan was worried for his sister. "When you went in, did Houtu tell you how much time had passed since I left?"

"Nearly six hundred years."

Meng Xiaoyu replied.

"Less than six hundred years?"

Meng Chuan raised an eyebrow. It seemed that, just as he had guessed, if there were no Blue Star people in the prehistoric world, the flow of time might return to "somewhat normal".

"Um."

Meng Xiaoyu nodded, and then continued talking about what happened next.

Upon learning that a hundred years before Meng Xiaoyu entered, Jieyin and Zhunti had already established the Western Sect and become saints, Meng Chuan was not surprised. In the original trajectory of the Primordial World, after the Three Pure Ones became saints, it was their turn.

"A hundred years after you went in, Yuanshi will surely have led them to the ancestral land of the Wu tribe, right?"

Upon hearing Meng Chuan's words, Meng Xiaoyu glared at him, annoyed. "Brother, you've been hiding this for too long! If Sister Houtu hadn't told me about you, I wouldn't have known you were already a Quasi-Saint, and that you once forced those three Saints to hide in the Demon Court for refuge!"

"Thank goodness they don't know I'm your sister, otherwise they'd probably tear me to pieces!"

Meng Chuan remained expressionless and said calmly, "Tell me about what happened back then."

Next, he learned from his sister that Yuanshi, Jieyin, and Zhunti had arrived with overwhelming killing intent. After discovering that they could not detect his presence, they slunk away.

His eyes narrowed to slits, and a murderous glint flashed in them!

When he learned that Tongtian would arrive almost immediately, his expression softened slightly. "Fellow Daoist Tongtian...you're very kind."

As for Lao Tzu, a cold smile involuntarily crept onto his lips.

There will eventually be a chance to settle accounts!

He will definitely find his way back!

Next, Meng Chuan continued listening to his sister recount what happened after the prehistoric era...

"Before I returned, the ten Golden Crow Princes of the Demon Court had already been born."

Meng Chuan learned from his sister that the great shaman Kuafu did not die chasing the sun, presumably because Houtu intervened.

Meng Chuan nodded, not too surprised.

Houtu already knew the course of history and couldn't bear to see Kuafu die, so she would definitely intervene.

But Da Yi still made his move and shot down nine golden crows!

The story of Yi shooting down the suns was the catalyst for the war between the Lich King and the Demon King...

Houtu, naturally, would not stop the plan, which was intended to be a secret passage.

"The Demon Emperor Jun and Donghuang Taiyi have both broken through to the peak of Quasi-Saint!"

Meng Xiaoyu continued, "Including Sister Houtu, all twelve Ancestral Witches have reached the peak of Quasi-Saint. A new round of the Witch-Demon War had already begun shortly before I returned."

"The Twelve Ancestral Witches formed the Great Array of Heavenly Gods and Demons, overwhelming the Demon Court's Zhou Tian Star Array and displaying boundless power!"

Meng Chuan picked up his teacup, took a sip, and remained calm.

The Great Array of Heavenly Gods and Demons, the true form of Pangu, is the ultimate trump card of the Ancestral Witches.

The Zhou Tian Star Array, the Demon Court's trump card, was said to be able to fight on par with a saint in the later stages of the Lich War.

When two great formations collide, it's normal for the former, which is powerful enough to overpower a saint, to be superior.

Meng Xiaoyu continued speaking...

But when she mentioned the human race, her voice suddenly lowered.

"Brother, the human race in the primordial world... is so pitiful."

She lowered her head, looking at her fingers. "All the races of the primordial world feed on them, hunting and killing them indiscriminately without any restraint. Before I came out, I even heard that the demon race was preparing to massacre the human race to forge the Witch-Slaying Sword!"

Meng Chuan paused, his hand holding the teacup still.

The Witch-Slaying Sword!

In order to deal with the physical body of the Ancestral Witch, the Demon Court slaughtered the human race and forged a vicious sword with the essence and blood of the human race!

The appearance of the Witch-Slaying Sword also signifies that the underground conspiracy is about to begin!

That was the "optimal timeframe" he set for Houtu.

He looked at his sister, his eyes filled with pity.

Good guy!

His sister is just too unlucky, isn't she?

The demon race is about to forge the Witch-Slaying Sword. If she could stay inside for another thousand or eight hundred years, she might be able to witness the rise of the underground passage and see Houtu become the Supreme Saint of the Underground Passage!

At that time, even if Houtu just spills a little something between her fingers and gives it to her, she'll take off!

However, he didn't tell his sister these things, afraid that she might do something rash.

He inquired about the interdimensional teleportation stone again and learned that neither Houtu nor the Ancestral Witches had been able to figure it out, which did not surprise him.

I wonder if Houtu will be able to fathom its mysteries after she achieves sainthood in the Dao!

Seeing that his sister had finished speaking, Meng Chuan raised his hand to stop her: "You just got back, go back to your room and rest for a bit... Mom and Dad went out to buy groceries, they should be back soon."

Meng Xiaoyu nodded, stood up, took a few steps, and then turned back.

"elder brother."

"Um?"

"Sister Houtu asked me to tell you—"

She looked at Meng Chuan and said, word by word, "The tunnel is about to be completed. She will wait for you and find her way."

Meng Chuan's hand, holding the teacup, froze in mid-air.

After a long while, he softly hummed in agreement.

"I see."

……

The Great Xia Dynasty, its capital.

In the underground conference room, technicians retrieved the information they had received from outer space:

"It was a message sent back by Senior Duan Lingtian... saying that he is aware of the recent situation on Blue Star that we reported, and he needs to confirm that Mr. Meng is indeed a late-stage Grand Luo Golden Immortal, rather than just a guess."

"He has now reached the early stage of the Great Luo realm, and has been hunted down by two mid-stage Great Luo cultivators for years, unable to shake them off... If he is not certain, he will not consider returning to Blue Star, fearing he might bring disaster to it!"

Upon hearing this, everyone looked at Lin Lei, who immediately contacted Meng Chuan to inform him of the matter.

Meng Chuan replied calmly, "Let him come back."

"As for those two mid-stage Great Luo... I'll let them keep my sister company for a while."
