Time Travel: Did My Sister-in-Law Get Slapped in the Face Today?

He could naturally see what Yan Zhanyu was thinking.

Yan Zhanyu nodded immediately, "Yes, disciple understands."

……

Soon after.

"Yan Zhanyu greets Brother Xuanyuan!"

Inside the academy's main hall, a black-haired old man in a silver robe sat upright, with a man and a woman standing behind him. Yan Zhanyu bowed.

"No need to be polite."

The black-haired elder, Xuanyuan Tongxuan, spoke calmly, saying, "I won't beat around the bush with you. I've come here this time for matters concerning the underworld."

“A few days ago, I sensed the aura of the interdimensional communication method. If I’m not mistaken, it should be an old ancestor of my Dao Palace who went missing thousands of years ago. He was exploring the underworld of Nan Yao Star when he mysteriously disappeared. Now that he has suddenly sent a message, there must be a major change.”

"That's why the Dao Palace sent me here to investigate. Judging from the spiritual yin mineral crystals you presented, that underworld should be about to collapse. Our ancestor must be trapped inside!"

Upon hearing this, Yan Zhan was taken aback. The Dao Palace was actually concerned about this matter!

Behind him, Li Lan, still holding Xu Caiwei's sword in its sheath, couldn't help but shudder. An ancestor of the Dao Palace?

Could the ancestor Xuanyuan Tongxuan spoke of be the same Heavenly Mystery Elder from the underworld? ...

It's very possible!

At that moment, Li Lan suddenly understood!

When the Big Black Dog, the Ninth Emperor, and others attacked Yangyi Village, the Old Man of Heavenly Secrets had ulterior motives. It was probably he who used the method of interdimensional communication, which is why he summoned that path that could traverse between the two worlds.

However, he was blocked by the Yang realm, and Li Lan seized the opportunity, embarking on this path and entering the Yang realm.

Therefore, the Old Man of Heavenly Secrets did all the work for Li Lan, but he himself was still trapped in the underworld!

"I heard that there's a girl in your academy who summoned a spirit from the underworld. Is that true?"

At this moment, Xuanyuan Tongxuan suddenly asked a question.

Yan Zhan hesitated for a moment, then said, "That's right."

As he spoke, he said to Xu Caiwei, "It is her. The yang soul that was guided has become her battle spirit and is now attached to her sword sheath."

Xuanyuan Tongxuan suddenly stood up and made a move. The sword in Xu Caiwei's hand flew out involuntarily and landed directly in his hand!

"My sword!"

Xu Caiwei's expression changed, and she wanted to make a move, but Yan Zhanyu stopped her and gently shook his head.

Xuanyuan Tongxuan picked up the longsword, then drew it out. With a burst of magical power, a beam of soul light flew out, waking up Li Lan who was in hibernation.

"Who are you? When did you enter the underworld, and how did you come out?"

Xuanyuan Tongxuan asked in a deep voice.

Li Lan shook her head and said, "I can't remember anything..."

Xuanyuan Tongxuan frowned and asked, "What is the underworld like where you are? Are there any figures like the Ancestor of Creation or the Goddess of Mending the Sky? Have you seen a dog or a cat?"

Li Lan's heart skipped a beat. This guy, Xuan Yuan Tong Xuan, actually knew so much?

It seems that this Taoist temple has quite a bit of knowledge about that underworld!

"I've forgotten everything..."

Li Lan gave a bitter smile and said, "I only remember that on my way here, there seemed to be a sea of ​​suffering, many dark palaces, and I also endured some cruel tortures such as boiling oil and climbing mountains of knives..."

He deliberately tested the waters.

As expected, Xuanyuan Tongxuan's expression changed drastically in an instant, and he said, "What? Reincarnation!?"

"This is impossible!"

He paced back and forth, muttering, "That person had already left the underworld back then, and the law of reincarnation should have been greatly broken, so why can he still appear in the underworld?"

Suddenly, he abruptly turned his head and stared at Li Lan, a yellow light flashing in his eyes as he carefully examined her.

After a long examination, he suddenly focused on Xu Caiwei and then nodded!

He had just become suspicious of Li Lan, but after careful examination, he realized that Li Lan had indeed become Xu Caiwei's battle spirit. The traces left by the master-servant ritual could not be faked.

It seems this yang spirit wasn't lying after all?

"If this cycle of reincarnation truly still exists, it could cause a huge uproar!"

Xuanyuan Tongxuan frowned deeply.

"Brother Dao, the concept of reincarnation only existed in ancient times. How could it arise in the underworld, and how could it cause chaos in the mortal realm?"

Yan Zhan wanted to ask a question.

"You don't know this,"

Xuanyuan Tongxuan said, "Yin and Yang are distinct; the dead must not set foot in the mortal realm. This is an absolute law!"

"In the ancient war, the Primordial Emperor Star Ancestral God perished, and all the immortals perished. In order to undo everything, many demon gods of the Emperor Star sacrificed themselves, creating their own karma, so that those vanished Primordial Emperor Star Ancestral Gods and immortals could reappear in the underworld. But even so, no one has ever been able to truly return from the underworld."

"Occasionally, a ghost may venture out of the underworld, but it will inevitably be struck by the power of the mortal realm, and its soul will be scattered!"

"But reincarnation can transcend the boundary between Yin and Yang, and the separation between life and death!"

These things weren't exactly top secrets among the upper echelons of the mortal realm, so he explained them to Yan Zhanyu and the others one by one:

"Once reincarnation truly occurs and breaks the laws, those beings who perished on the Primordial Emperor Star will surely reappear one by one... War will reignite, and the entire mortal realm will likely be slaughtered and shattered!"

His words were incredibly heavy!

Yan Zhanyu was shocked. Although he was the dean of Nantian Academy, his cultivation level was not high enough and his status was not high enough. Therefore, this was the first time he had heard these top secrets!

Li Lan felt extremely solemn!

According to Xuanyuan Tongxuan, the existence of the underworld was due to the ancient demon gods, who sought to bring back the vanished ancestral gods and immortals.

If that's the case, then everything makes sense...

Could the so-called creators and goddesses who mended the heavens in the underworld be none other than Pangu and Nuwa, the famous beings from the Primordial Emperor Star?

They are resurrected in the underworld, reappear, and finally cross the gap between the living and the dead to enter the living world.

Who exactly is the owner of the big black dog and the cat? Is he the one who orchestrated the cycle of reincarnation, and the mastermind behind this grand plan to resurrect the powerful beings of the Primordial Emperor Star?

Moreover, in the underworld, people generally believe that the sudden disappearance of the creator god and the goddess who mended the sky was due to some problem at the source. But now it seems that they simply left the underworld and came to the mortal world.

What happened in the mortal realm? Three unimaginable beings were forced to be born prematurely, abandoning the grand plan of reincarnation.

After all, since that being created the cycle of reincarnation, should have wanted to use it to reverse yin and yang and guide the beings of the underworld.

His sudden departure caused the underworld's reincarnation system to break down. There must have been some major upheaval in the mortal world that forced him to leave!

Otherwise, Li Lan wouldn't have needed to start dealing with the cycle of reincarnation so late today!

Moreover, judging from Xuanyuan Tongxuan's words, it seems that the upper echelons of the mortal realm are extremely wary of the return of the underworld, and even have a sense of vigilance. Why is that?

All of this is crucial, originating and ending in the so-called ancient war.

However, Li Lan searched through the entire library of Nantian Academy but couldn't find a single record of it. Why was that?

...shrouded in mystery!

"In the ancient war, the ancestral gods perished, the immortals were destroyed, and the demon god sacrificed himself in the underworld, bringing everything back to life..."

Numerous clues intertwine, seemingly veiled by layers of mystery, making the truth difficult to discern!

"No, I have to find a way to go to the underworld."

Xuanyuan Tongxuan suddenly spoke up, saying, "I would like to trouble the Southern Heaven Academy to prepare some items for us to communicate with Yin. In addition to the spiritual Yin mineral crystals, we also need incense for communicating with Yin and incense money. Is it possible to find these items?"

Yan Zhan bowed slightly and said, "I do have incense for incense burning, but the money for incense offerings is already very scarce. Please grant me a few more days, fellow Daoist!"

Xuanyuan Tongxuan nodded and said, "Alright, also, select three more men and three more women. I want to personally go to the embankment in the underworld to pay homage to that source god of the underworld!"

Upon hearing this, Li Lan's eyes lit up!

Heading to the dike to pay homage to the source?!

Do people in the mortal world really have a way to go directly to the underworld, and even a way to get onto the dam?

However, it is not surprising, after all, the old man of the Heavenly Secrets was captured on the dam and used to refine stone corpses!

Li Lan immediately realized that this was a golden opportunity!

Not only can you return to the underworld, but you can also explore the depths of the source!
