Song of Adolescence - Chapter 5: Heavenly Maiden Rui

Yan Xi was the eldest young lady of Beiqiao City’s top four families, the Yan family. Despite her talents, she was sickly and destined to die young. She was an unattainable dream girl for many.

One day, she had a dream, and the setting was in a novel. In the novel, for the sake of alleviating his pain of losing his wife, and soon his daughter as well, her father adopted a girl named Chen Xiangxiang who looked just like her. The girl was docile as a deer and very therapeutic, which made her all the more lovable. This girl became her substitute, and after a series of heart-wrenching incidents, everyone, from her father, brother, fiance, to her friends, they all doted on this girl. Meanwhile, she, the real rich daughter, was schemed against. After being disfigured, she jumped from a building and fell to her death.

Now, she returned to the moment when she was just discharged and before the tragedies happened. She lowered her head and looked at the person before her. She smirked. This time, she would control every development, and those who intended to harm her could forget about escaping.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

500 years ago, Chen Xi was devoured by a crack in the void and was transported into a cultivation world.

500 years later, he returned back to Earth after enduring through several hardships and discovered that only 5 years had gone by.

…

In the courtyard, beauty at the side, a candle flame wavering.

A gush of clear wind, half a full moon, the peach tree remains unchanging.

…

Wait, whose kid is this?! Why is she calling me papa? Gazing at the little girl in front of him with skin as pale as jade, Chen Xi froze.

…

　
Returning home from cultivation, starting as a stay-at-home dad.

In this life, not fighting to be a king nor claiming to be a tyrant, only praying to peacefully be a wife-pampering mad devil and a child-protecting daddy!
