From Under One Person: Sincere Journey Through the Heavens

Dayu was also confused.

Chen Long was even more confused.

“For example, suppose you are a self-loathing person who was beaten by your parents since childhood and is planning to go back in time to kill your grandmother so that your father could not be born. Then the question is, since your father was not born, would you be born?” Jiang Liu said, stating the grandmother paradox that does not exist in this world.

“How could there be such a despicable person in the world? But if such a person really existed, and he even went back in time to kill his grandmother, then he certainly wouldn’t exist; he would have disappeared.” Xiaoyu initially denied the possibility of “the grandson who killed his grandmother,” but she still expressed her thoughts.

Da Yu also thought so.

"So, since 'he' changed the past, killed his grandmother, causing the future 'him' to not exist, how could a 'him' who doesn't exist at all return to the past? And how could his grandmother have died?" Seeing that Dayu and Xiaoyu had fallen into the trap, Jiang Liu continued to ask.

"This... He went back in time and killed his grandmother. In the future, he was never born. But how could someone who was never born go back in time and kill his grandmother? Is he a ghost?"

Xiaoyu was confused. She shook her head and began to unravel the mystery by following the principle of "grasping the main points and then looking for patterns."

However, when it comes to the "paradox" of time travel, Xiaoyu, with her current level of knowledge, simply doesn't know how to classify it in a progressive manner.

"what is going on?"

Chen Long was also confused, and he personally experienced going back to the past, and a scar on his arm disappeared as a result.

In his view, changing the past can absolutely influence the present and the future.

However, Jiang Liu's "grandmother" hypothesis negates this possibility.

and so--

Which one is correct?

"I'm referring to the situation in normal spacetime."

Jiang Liu reminded him again, then raised his finger and drew a white stream of Qi in mid-air.

"Imagine this is a river of time, with a beginning, the moment the universe was born; and an end, the moment the universe perished."

"In a normal universe, time and space are inseparable. If someone could truly travel through time and go back to the past—"

As they spoke, a wisp of Qi detached from the white Qi stream, flowed upstream, and arrived at a certain point in the past.

hum!

At that point, another white stream of Qi split off, forming two rivers of time.

“In normal spacetime, as long as you go back to the past, even if you do nothing, your very existence is enough to cause a tremor in the entire universe at the microscopic level of spacetime, thus splitting the river of time and giving birth to another timeline, a spacetime with the same origin but a completely different future.”

"Therefore, changing the past cannot change the future of the time traveler's original timeline; it only creates a completely different future."

# Chapter 824 Grandmother Does Not Exist (Part 2)

"But the world we live in is... not quite the same as the time and space you came from."

Da Yu understood Jiang Liu's statement: "Here, changing the past can change the future, but it won't create a new timeline."

Uncle Long can be my witness.

"The last time I traveled through time, I almost caused Uncle Long to drown when he was a child."

"Um... could you please not use me as an example? I don't really like that memory." Chen Long felt offended once again.

"Sorry, Uncle Long, but there's an example right in front of us." Da Yu spread his hands and gave an embarrassed smile.

Fortunately, Chen Long didn't dwell on this point.

With a flick of his finger, Jiang Liu caused the two rivers of time to merge back into one, forming a continuous loop.

"The world you live in, namely the Earth-Moon system, is covered by the Zhouqi Bureau and is independent of the universe, so the attribute of time has been isolated."

"The past has no beginning, the future has no end, forming a cycle on its own."

"Therefore, within the system of planets and satellites, Earth and the Moon, the past, present, and future have become a true unity."

"Only in this way can the grandmother paradox cease to be a paradox and become a simple and brutal fact: change the past, and you can change the future."

After realizing the anomaly of her own timeline, Xiaoyu asked, "Isn't this a good thing? Our world is more perfect than other timelines, and we can change the past to salvage the future."

"Yes, it's quite perfect. So perfect that when people encounter trouble, they might not think of other ways to solve it, but instead keep thinking about changing the past."

Jiang Liu rolled his eyes. "If you want to become a true cultivator, the most important thing is to stay true to yourself amidst the trials of time and move forward with the flow of time..."

During this process, if one has the ability and reaches a certain level, one can use magical artifacts to experience the scenery of other parallel universes.

This is akin to early humans leaving their habitat to explore entirely new worlds! It's about remembering one's original aspirations after experiencing joy and sorrow, gathering one's strength, and embarking on a brand new adventure!

But going against the flow of time—

But that's just playing with 'time,' even if it's for a better future.

A wise man once said: "Those who play with time will ultimately be played by time."

At this point, Jiang Liu paused, his discerning eye having surveyed the vast world and seen through the true nature of the jade:

Although it is a body of flesh and blood, there is no light point bestowed upon it by others at the ancestral aperture between its eyebrows.

therefore!

This timeline, which has no beginning and no end, is not perfectly round, but rather has a definite "present tense"!

Taking this "present" as the true "now", everything in the "future" is an illusion. That is, this Da Yu who traveled from the future is just one of the possibilities that Xiao Yu might grow into in the future. It is a dream, a bubble. However, because it has come to the "now", this possibility of the future has been solidified in the present.

True!

This large jade is no different from a real life, with a soul, innate Qi, and sincere emotions, but in essence it is the embodiment of a possible projection of Xiaoyu in the future timeline!

"You mean, I'm some kind of illusion or projection?"

Disbelief filled Da Yu's eyes.

Jiang Liu rotated his finger and touched the ring of white Qi, causing a bead-shaped Qi ball to appear on it: "If we take this Qi bead as our present state and designate it to revolve in one direction, its direction of progress is the future, and what follows is the past."

Normal spacetime:

Everything in the past is fixed and cannot be changed. Even if someone were to travel back in time, it would only create a completely new branch of time, which is essentially still in the 'present continuous tense', rather than actually changing the time traveler's original timeline.

The future is a dream, not a reality, and people from the future cannot return to the present that is currently unfolding.

But what about your time and space?

The present is in progress; the illusory future and the real past are intertwined, making the concept of 'past' concrete, and thus adding a dreamlike quality to this fixed and unchangeable fact.

Upon hearing this, Chen Long suddenly realized: "No wonder Xiao Yu was able to change me in the present when she accidentally traveled to the past with the rabbit talisman last time... It's because the illusory future was connected with the established past, making the past illusory as well!"

Similarly, the illusory future also gains a sense of reality because it is connected to the established past.

Therefore, the most likely future presents a realistic picture, essentially setting a 'script' for the present, thus eliminating other possibilities.

Jiang Liu's gaze was extremely serious. "This kind of circular timeline is actually very dangerous because a person's memory, soul, will, spirit, and mind all need to grow over the years. Once the past changes, the experiences will change, and the memories will naturally increase or decrease, thus causing a person's personality to change."

How can you be so sure that now is *now*?

Da Yu still held onto hope, "What you consider the future is, for me, the present! It's absolutely real!"

"There are two pieces of evidence."

Jiang Liu held up two fingers. "First, Lu Jin, Duanmu Ying, and I are visitors from another world. Although we don't have much experience in time travel, I can personally confirm one thing: the time we came from across time is definitely in the present moment of the river of time."

Using this as an anchor point, the flow of time between different times and spaces can be relatively still, thus making the connection between times and spaces possible.

The second one—

Close your eyes, enter your inner vision, and see if there is a point of light within your ancestral aperture at the center of your forehead. That is a unique gift I gave to Xiaoyu.

Da Yu followed her instructions and entered her inner world with a single thought, but her spiritual realm was hazy and devoid of any light. When she came to her senses again, her eyes were filled with disappointment, and she murmured, "I... I remember it has always existed. Could it be that I am really Xiao Yu's illusory future possibility? And is everything in the future just an illusion?"

"Big jade..."

Chen Long opened his mouth, but didn't know how to comfort him.

Xiaoyu moved closer to Dayu, took her hand, and asked, "Hey! This isn't like me! No matter what, you are me from the future!"

"Did you know? The past, present, and future are one and connected, making the past and future a mixture of illusion and reality."

Jiang Liu also comforted her, saying, "In this 'present tense' that I am in, you are no longer an illusion, but an interweaving of illusion and reality. If you stay in this 'present' for a long time, you will eventually become real and become another Xiaoyu, only more mature and sensible."

"That's wonderful! I can have a big sister now!"

Xiaoyu exclaimed, "Dayu, why don't you stay? We can create a brand new future together!"

First, we need to find the little devil dragon;

Then, collect the fire energy within his body;

Finally, we gave him a good kick in the butt!

What do you think?

Da Yu covered her head and said, "I think I might need some time to calm down."

# Chapter 825 Panku Treasure Box

"Wait, don't you want to stay?"

Seeing Dayu go up the stairs, Xiaoyu called out.

"Xiaoyu, I think... Dayu really needs some peace and quiet."

Chen Long pulled Xiao Yu back.

Honestly.

By immersing himself in the world of Da Yu, Chen Long learned the truth about the timeline of their Earth-Moon system and realized that his future was an illusion, only appearing real because the timeline was connected to the predetermined past... Chen Long was certain that even he himself would not have been able to accept this fact immediately.

After all, Xiaoyu, who comes from the "future," also has a lot of past memories in her mind.

Does she have to do it all at once?

Does this mean that all future memories after the present are false?

Does she acknowledge that she herself is merely a false possibility of Xiaoyu's future, and that it is only because the future is connected to the past that one of the most likely possibilities for Xiaoyu's future has gained a touch of reality, thus enabling her to travel to their present?

Does she acknowledge that, apart from herself who has already arrived in the "present," her future father, Chen Long, and everyone else are all dead illusions?
