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

Hearing Li Lan's words, the girl's anger subsided slightly, and she said with annoyance, "Such a big mistake on my first try, it's so annoying! If my senior sister and master find out, they will definitely laugh at me!"

"You said you had to cooperate with me and cancel the contract, otherwise, hmph!"

She brandished the imperial seal in her hand threateningly.

Li Lan couldn't help but chuckle to himself. Having experienced countless life-and-death battles and witnessed countless powerful figures in the underworld, Xu Caiwei was practically invisible to him.

Although she was angry just now, she didn't really intend to kill anyone; she's actually a kind person.

"Remember this: from this moment on, you are my battle spirit. If anyone asks, you must say, 'I am the master,' understand?"

Her earnest advice!

We must bring this guy back to the academy now, but we must keep it a secret and not let anyone else know.

"Okay." Li Lan smiled.

Xu Caiwei nodded. "Since you came out of here, it means there must be a hellish place here. Hmm, we need to leave quickly..."

"Once you're caught up in the underworld, there's basically no way to come back without someone to guide you, especially for living beings in the mortal realm, who might even be eaten by the spirits of the underworld!"

"Let's go!"

She spoke, and Li Lan followed her.

"What is this place? Are there many underworlds here?"

On the way, Li Lan asked questions indirectly.

Xu Caiwei glanced at Li Lan with a hint of doubt, then explained one by one:

"This is Nanyao Star in the Ziwei Star Region. The Ziwei Star Region is one of the three great cosmic immortal regions. In addition to the Ziwei main star, there are three thousand planets, and Nanyao Star is one of them."

Upon hearing this, Li Lan couldn't help but ask in confusion, "The three great cosmic immortal realms?"

Xu Caiwei said, "You can't even remember this? Your amnesia is too complete... The three great cosmic immortal domains, the Ziwei Star Domain, the Beidou Star Domain, and the Siling Star Domain!"

"If you weren't actually a spirit from the mortal realm, I would have suspected that I had summoned a ghost from the underworld."

Li Lan couldn't help but feel a little dazed. Ziwei, Beidou, Siling...aren't these all ancient Chinese celestial names?

Furthermore, given Xu Caiwei's repeated mentions that he is a soul from the mortal realm, could this so-called mortal universe be the same universe where Earth was before he transmigrated?!

"By the way, in the underworld you traveled to, were there any Nuwa, Pangu, or other such beings?"

At this moment, Xu Caiwei suddenly asked curiously, "Many years ago, Pangu, Nuwa, and other ancestral gods who had long since vanished from the mortal realm emerged from a realm of the dead. Accompanying them was an unimaginable being... Some say that the realm of the dead was deliberately created by someone to bring back some peerless powerhouses..."

"There are still many forces searching for that underworld."

Upon hearing this, Li Lan was immediately shocked!

If he was only guessing before, now that Xu Caiwei mentioned the names of the two ancestral gods, Pangu and Nuwa, he was almost certain...

Is the so-called "Yang Realm" simply the universe where Earth is located?

When he traveled through time, did he enter a realm of the dead?

Now that he's returned to the mortal realm... has he simply returned to the world he originally inhabited?

Perhaps only in this way can we explain why he is not afraid of yang energy, because he is from this world!

……

"Nuwa, Pangu? Who are these people? They sound somewhat familiar..."

Although his heart was filled with turmoil, Li Lan calmly asked the question.

"Nuwa and Pangu were the first powerful beings to emerge from the Primordial Emperor Star in ancient times. They once illuminated the heavens and were awe-inspiring throughout the ages. However, they both perished later. It wasn't until several thousand years ago that two figures, who were suspected to be their reincarnations, emerged from a certain underworld."

Xu Caiwei, with her cheerful and lively personality, patiently and tirelessly talked to Li Lan.

What is the Primordial Emperor Star?

"The Primordial Emperor Star... is a very powerful ancestral star for cultivation. Pangu, Nuwa, the Three Sovereigns and Five Emperors, Laozi, who is known as the Ancestor of Taoism, and the Buddha who founded the Buddhist sect... all these extremely powerful ancestral gods and immortals came from that ancestral star."
