Because everyone who leaves must undergo memory elimination.
As for how it's eliminated, Jiang Si doesn't remember either; by the time he came to his senses, he was already home.
The parents' coffins were placed in the hall, and relatives crowded the house, murmuring on and on... Jiang Si wasn't in the mood to listen.
The funeral process was tedious and cumbersome, being pulled around from place to place, but as soon as it ended, Jiang Si would disappear immediately.
Naturally, there's no way to cry, nor is there any nostalgia for his parents. Whenever pulled into discussions for too long, his impatient expression was barely concealed.
Gradually, whispers began among the relatives, and their attitude affected his sister.
The day before the burial, his sister begged him to join in sending their parents off.
But Jiang Si ignored it.
Later, at the cemetery, before the burial, his sister lay on the coffin crying.
Jiang Si did not attend the funeral, nor did he even go see his parents one last time.
It was raining that day; he only looked on from afar.
The gentle patter of rain soaked the tombstone, and the somber cries of the crowd were drowned by the rain, leaving only the suffocating repression, as if all laughter and beauty of the world were buried with each shovelful of wet earth.
Gradually, only dead silence remained.
Involuntarily, he thought back to the past, the first time his mother got angry in his previous life, also on a rainy day, throwing a novel in his face.
"Wake up!"
His father tore his book apart, stuffing the scraps into the fireplace.
Demanding he study properly.
His parents went from anger to disappointment, and finally to indifference.
He couldn't blame them for not understanding, because he knew himself.
When he chose this path, it was destined to be misunderstood.
He only tried to meet their expectations, then continued forward.
He scoured all the ancient texts, consulted every mystical person, whether religious, martial arts, Qi Gong, or Magic.
Each disappointment piled up into ever greater crashing waves.
"Wake up."
Jiang Si rolled up his sleeves.
The blood on his arm was rinsed by the rain.
Even with his memory erased, the words gouged out with his nails were hazy but clear enough to read.
I want to become a Magical Girl.
This world's Extraordinary Power, Magical Girl.
With this power, he could embark on the true path of Cultivation Immortality.
However, only girls can become Magical Girls.
Despair?
"I've faced too much despair in my life."
He walked forward, the coffin behind him thoroughly buried in the earth, his sister's sharp, piercing cries tearing through the curtain of rain.
Jiang Si reached out his hand, looking up at the sky.
The icy rain soaked his soul.
"Isn't it said that heaven always leaves a path?"
The roots of the Disaster Beast embedded within him were pulled out, nourished by massive negative emotions, they swelled and grew.
Despair from the Disaster Beast permeated.
And, the intense wish to devour everything in this world!
"As long as I wish to go, the path lies before my feet!"
"I will become a Magical Girl!"
His tightly clenched fist seemed to grasp something, as if it had already caught hold of something.
Bits of starlight trickled from between his fingers, merging into a dazzling rainbow light!
A lace-and-ribbon adorned Lolita-style gown, purple and gold intertwined, and luxurious boots gently stepped on the muddy ground.
Her long purple hair danced in the rain.
Like a blooming flower.
Her cherubic face reflected in the rainwater.
In an instant, she seized the swollen, twisted roots; the purple Magic Power burned them away in the rain like flames!
"Henceforth, I shall prevail through eternity!"
