"Are the past we are returning to the same line as the original future? Or are they similar to parallel relationships? ”

Estelle was hurriedly flipping through the notes that she had taken out of nowhere at this time, when she heard Yahara suddenly ask, sighed, closed the notebook and explained.

"Your conjecture is correct, I collected a lot of literature when I studied the magic of going back in time, but everyone who completed the magic of going back to the past got the same [even if I go back to the past, nothing will change].

"Our past is a definite past, a past that cannot be changed.

For example, if we live in a world of A, then it was determined ten years ago because we had a future because we didn't interfere.

And the past that we can interfere with is the past of world B, and we will still return to the future of world A, to the original world. ”

After racking her brains to explain the current situation, Estelle only felt dizzy in her head, and felt like she was going to fall.

Sure enough, I'm not a brainstorm.

After listening to her explanation, Yahara thought for a moment, and then remembered the "grandfather paradox" that he had seen, You can't go back in time and kill your grandfather.

There is an irreversible relationship between Serena's death and Estelle, the future is controllable, and history is already predestined.

But... No matter what ABCD world you are in, this timeline from ten years ago shouldn't have itself, is it fate that no matter what you do, you will go back to where you are?

Thinking of this, Yahara couldn't help but look around, would the A world that had already been formed have the intervention of the B world ten years later?

If it's true, according to your character, you should leave something behind, and when you go back, you must search it carefully.

"Hey, it's time to go, in about twenty minutes there will be robbers attacking Serena's house, killing her parents and stealing their belongings, we don't have time." Estelle shook the note in her hand, urging Yahara to speed up.

But the magic of employing people is soft, and the tone should be polite.

"Got it." Thinking that World A might have something left by itself from other worlds, Yahara felt a sense of relief in his heart, Looking at it this way, Estelle's research on time magic is still good.

Suddenly, Estelle, who was walking in front, stopped, her golden pupils instantly dilated, and her mouth opened, looking very shocked.

A few question marks popped up on the door of her head, and Yahara looked along her line of sight, a little girl with glass-colored eyes and long straight black hair swaying her body and holding a large bag of things, absentmindedly walking on the road.

"Serena...!"

Estelle let out a hoarse voice that barely squeezed out of her throat, and her body involuntarily stepped forward to meet her best friend in her memory.

But failed.

A long, white hand grabbed her wrist.

"Don't be impulsive, I'll go and observe." Yahara's eyes darkened, and his pupils locked on Serena, but his voice was unmistakably oppressive.

The first time she saw the solemn Yahara, Estelle was stunned for a moment, and the left foot she had just stepped out was retracted, but her heart was full of doubts.

Serena was still staggering and walking with something in her arms, but with her petite size, she even had to tilt her head sideways to see the direction ahead, so she didn't notice the "giant" emerging from above.

"Ah, little friend, why did you bring such a heavy thing back by yourself?"

Yahara walked to Serena's side, squatted beside her, and greeted her tenderly.

Estelle, who was on the side, was even more puzzled, she thought that Yehara had found something unusual before she went, but that's it?

Smiling and showing his non-malicious side, a shadow quietly appeared in Yehara's heart, and his vigilance was also raised.

This lovely and gentle ...... in front of you Or a little girl with a gentle skin, the fluctuations of negative emotions are more violent than that of ordinary adults!

Dirt, dirt, hatred, and other negative malices that do not belong to children fill Serena's heart, and even overflow, and things are definitely not as simple as Estelle says.

"Who are you, big brother?" Serena blinked, vaguely afraid.

It was a terrible feeling to be helpless, and without evil as a medium, he could not perform inaction, and he would not be able to probe Serena's soul and find the truth about her growth.

"Well, I'm a passing Kamen Rider." Staring at Serena's glass-colored pupils, the surging innocence revealed made Yahara unable to believe the negative fluctuations he had just felt.

"What's that?" Serena was stunned for a moment, and then looked up at the sky: "Ah, I should go back, goodbye strange big brother." ”

After saying that, he was about to leave with his little short legs.

But Yahara stopped her again and gave Estelle a look, signaling her to go to Serena's house first to save her parents.

He wants to figure out why Serena has become like this inside!

Listening to the footsteps in the distance, the narrow alley was finally left with only Yahara and Serena.

"Kid, can I send you home?"

"Huh?" Serena's eyes widened, and she couldn't help but tighten the bag in her hand, and took two steps back vigilantly: "No, I can do it myself." ”

What exactly is this person going to do? It's getting too late, otherwise Mom and Dad ......

There's no way to kill it?!

A long and narrow black knife suddenly appeared in Yahara's hand, exuding a cold aura and a vague rhythm of breathing.

"I'm sorry, you can rest for a while." The soles of his feet slid lightly on the ground, and the strong wind blew, and Yahara came behind Serena in the blink of an eye, silently stunning her, letting her rest on his right arm.

At this time, the bag that she was holding tightly also fell to the ground, making a crisp golden sound.

Yahara's eyes were slightly condensed, and he opened it with one hand to see that inside was a black cloak and a sharp dagger that shone with cold light.

Hiss~

He couldn't help but gasp, and looked at Selena who was sleeping in disbelief, breathing steadily, and still having the innocence and cuteness of a child on his face.

What can make a little girl about ten years old disguise her identity and not hesitate to kill her parents?

"Transform without doing anything!"

A bizarre streamer flashed, and in the eyes of Yahara, a well-dressed and elegant couple appeared in a cozy wooden house, with all kinds of precious furniture and gold jewelry neatly arranged.

The scene flashes to a clip of Serena alone with her father.

However, the warm and beautiful coexistence of father and daughter has completely deteriorated, and the gentle words make Serena completely fall into the trap and trap of her father, and begin to fall into the abyss for the first step.

Small kiosk

Then, there is the picture of her mother's appearance, who ignores the fear and pleading in Serena's eyes, and the malicious ridicule and abuse constantly hit her heart, and even confines and drips wax oil to punish her when she is angry.

It's like treating a lover who seduces her husband.

Time flies, day and night alternate and renew, and Serena's bright glass-colored pupils lose their light.
