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

"Different paths lead to the same destination. We embark on our journeys in confusion, see the truth in the illusion, and finally open the door. This may be the end point that both the cultivation in the underworld and the world of the living will face."

Li Lan murmured, "If that's the case, can beings from the underworld directly continue cultivating their previous Dao after entering the mortal realm?"

"The world changes, the Great Dao shifts, and times change. The ancient Great Dao has lost its foundation in this world, like a castle in the air. If one does not cultivate a path that aligns with the Great Dao of this era, one's cultivation will gradually diminish, eventually turning into a pile of dust!"

However, this idea was soon answered, as relevant content was recorded in several old and worn books.

The beings in the underworld, those at the peak of the Great Luo Golden Immortal realm, were in no way weaker than the current One Thought Returning to Origin realm experts, but ultimately, the world had changed.

Therefore, it is still necessary to retrace the path of cultivation in the mortal realm.

However, if someone has already cultivated to an extremely high level in the underworld, after returning to the living world, they are often revered as a heaven-defying genius and sought after by all sides!

Because their understanding of the Great Dao, their insights into cultivation, as well as their Daoist heart, will, and talent are all different from ordinary people. In fact, people who have returned from the underworld can cultivate without any bottlenecks and can grow rapidly in a very short time.

In fact, Li Lan had already discovered this. The scriptures in the library were all cultivation methods from the mortal realm. Although they were different from the underworld system, in his eyes they were extremely simple and without any difficulty.

"Can people from the underworld really be brought back to life?"

Li Lan was more concerned about this point, but after searching through all the books on the first floor, he found no further discussion on resurrection, so he floated up to the second floor.

There were hardly any people on the second floor, but Li Lan searched quickly as usual, and soon he finally found some information about the theory of resurrection:

Throughout history, no more than ten people have successfully returned to life!

There exists a natural barrier between the underworld and the mortal world, which is suppressed by the Heavenly Dao of the entire mortal world. Creatures in the underworld will be dissolved and destroyed if they touch the yang energy.

How does one return to the mortal realm? No one in the world knows. Even the few people in history who are clearly recorded—how they returned to the mortal realm remains a mystery. Various forces and experts have conducted countless studies, but ultimately, they all attribute it to a series of coincidences.

Li Lan couldn't help but sigh, it seems that reviving someone is truly extremely difficult!

Therefore, he recalled that the master of the White Emperor and Black Emperor in the underworld actually came up with a method to use reincarnation to save all the spirits in the world... If successful, it would probably rewrite the entire history and shake the mortal world to its core!

According to the information he has now obtained, the creator of the underworld and the goddess who mended the sky should have already entered the mortal world. Could it be that she has also come to the mortal world a long time ago?

We don't know yet; we'll have to find out later.

"How did the underworld come about?" Li Lan asked, like a thirsty student, searching for all sorts of knowledge.

He found the information he wanted in a book called "A Detailed Explanation of the Underworld".

There are many underworlds in this world!

Every underworld has a source of origin!

source!

Li Lan felt extremely solemn. Could it be that the source of the chaos that had plagued the underworld for countless years was actually described in the ancient texts of the mortal world?

"Ancient Demon God!"

Li Lan carefully flipped through the pages, and four words caught his eye on the yellowed bamboo slips!

"In the ancient war, the demon god reversed the balance of Yin and Yang and sacrificed himself to create the underworld, which contains cause and effect and the passage of time."

"However, when Yin and Yang are in disarray, the nature of demons and gods is divided into two. The benevolent corpse gives birth to all things, while the malevolent corpse destroys all spirits. Therefore, the underworld is left to its own devices, and the mortal world often does not need to intervene."

This was a fragmented bronze slip, containing only two short lines of text, yet it still deeply shocked Li Lan!

Ancient demon gods sacrificed themselves to create the underworld. However, in the chaos of yin and yang, the demon gods' good and evil selves separated. The good selves gave birth to all things, so the underworld also has heaven and earth, and a world and creatures that look no different from the mortal world.
