The wind at night was slightly cool, and the starry sky, which was already full of stars, was already pitch black, and even the already dim moon was no longer visible.

The leaves on the side of the road rustled and fell from the trees, and an older apartment was dimly lit, and the surrounding buildings had turned off their lights to rest, making the apartment the only light in the night.

A figure was busy in the lighted room, the floor was full of books, and beside him, the only empty space, stood a little man who was holding a book and looking at it with relish.

"Yin, it's already past twelve o'clock, you have to attend the school speech tomorrow, so don't accompany me." The young man put down the things in his hand, glanced at the clock hanging on the wall, looked at the girl distressedly, and said softly.

"I promised my brother not to help this time, brother, you can't be untrustworthy." The girl raised her head, her eyes were faint, but the stubbornness in her eyes was clearly expressed, and the young man, who knew the girl's temper, sighed helplessly, and had to give up.

Chen Yin then lowered his head, and was slightly stunned when his gaze accidentally swept over the book that Chen Ling was holding just now. She quickly raised her head and saw that Chen Ling seemed to be about to put the book back on the shelf, so she hurriedly stopped it, "Wait a minute!" Brother, there seem to be traces of folding on this book. ”

Before Chen Ling could react, Chen Yin stepped forward and quickly pulled out the book, and then spread it out.

The book has been yellowed, the pages are shaggy, and it is obvious that people often turn it over, but the book is very well preserved, and those broken places have long been glued with transparent glue, which shows that the original owner of the book liked the book very much. But in the lower corner of the book, there is a small corner, and there is more than that, which is why Chen Yin was able to find it in the first place.

"These are ......" Chen Yin flipped through the other pages and found that wherever there were folded corners, there would be words circled in red.

"This is my father's favorite book, and I used to see him reading it." Chen Ling seemed to remember some good memory, with a faint smile on his face.

However, Chen Yin frowned, with her naturally very keen intuition, the words that her father circled in the book were definitely not simple! Perhaps, it is some code code.

And the truth was just as she guessed, she found a pen and paper and wrote down those words in order, but soon Chen Yin found that there seemed to be something missing, so she couldn't form these words into sentences.

"By the way, brother, what about your parents' codebook?"

Chen Yin suddenly remembered the codebook that had been dusty for many years, she remembered that she had only seen that book once, at that time she was still very curious to ask her father what the book was, now she doesn't remember what her father's answer was, she only knew that the book was very important, so whether this book could be opened or not, they were very careful to keep it.

Although she didn't know what the connection was between the two, Chen Yin always felt that as long as she unraveled the words on it, as long as she could open the codebook, the reason for her parents' disappearance would be clear.

Out of trust in his sister, although Chen Ling was a little puzzled, he took out a box from the drawer of the table without asking anything, took out the codebook in the box and handed it to Chen Yin.

Looking at the codebook, Chen Yin's vision suddenly became a little blurred, and Chen Ling looked at Chen Yin worriedly, his eyes full of distress.

For those who have parents clearly in their minds, but can only rely on each other, their parents are their biggest misses, and now when they see their parents' things, the thoughts in their hearts have turned into hot tears with the grievances they have suffered over the years.

Chen Ling raised his sleeve and wiped his eyes fiercely.

"By the way, I remember that my mother seemed to have a book that we wouldn't touch. Since there are doubts in Dad's book, is there also a book in Mom's? ”

Unable to bear to see the dazzling loss in his sister's eyes, Chen Ling snorted and hurriedly found the book they had only seen the cover.

Originally, he just wanted to distract Chen Yin, but when he opened the book, he found that the book also had folded corners and circled characters, the only difference was that the book was circled with a black pen.

Chen Ling was slightly stunned, and then he couldn't cry or laugh, he just said it casually, but he didn't expect it to really exist.

Chen Yin looked at the words on it carefully, this time, there were very few words on the book, so few that she and Chen Ling got the answer in an instant.

"Goddess of Darkness?" Chen Yin frowned, constantly thinking about the meaning of these four words.

Looking at the four familiar words on the paper, Chen Ling inexplicably remembered the movie "Goddess of Darkness" that he had watched at a friend's house before.

“Dark Goddess 。” Chen Ling seemed to unconsciously spit out a string of English.

"Dark Goddess......" Chen Yin first glanced at Chen Ling suspiciously, and then cast her eyes on those four words, there was a thick puzzle in her eyes, she knew that Chen Lingnian's English meaning was the Dark Goddess, but the Dark Goddess, Dark Goddess...... What does that mean?

Chen Ling and Chen Yin thought hard.

When Chen Ling and Chen Yin's attention was on the words "Dark Goddess", they didn't see that in the codebook lying quietly on the table, a blue dark light suddenly flashed, and it was fleeting.

Whining......

The cold wind outside blew in, and in the wind, mixed with a few drops of cold water, hit in.

"It's raining." Chen Ling came back to his senses, looked at the window that was gently shaking and making a "creaking" sound, and walked over, he was about to close the window, but at this time, his body was frozen there, his eyes were fixed on a certain place across the road, his face was obviously afraid, and his body trembled faintly.

"Brother, what's wrong?" Chen Yin looked at Chen Ling suspiciously, walked over, but didn't see anything, so he asked in confusion.

Chen Ling came back to his senses, he closed the window, locked it, and then turned his head, his pale face trying to pull out a smile, "Oh, I was thinking about the meaning of the dark goddess just now, so I was a little distracted." ”

"Really?" Chen Yin looked at Chen Ling suspiciously, and the latter nodded busily.

"Okay, our priority now is to solve the puzzle, don't think about the rest!" Seeing that Chen Yin was still a little unconvinced, Chen Ling pushed Chen Yin back to the desk. Before walking away, Chen Ling looked in that direction again, but all he saw was the white street lamp.

Sure enough, I think too much.

Chen Ling retracted his gaze and smiled again.

Perhaps he would have turned his head a few seconds later to see a leaf falling from a tree, pausing for a moment on the way down, then falling to the ground as if crushed by something, and then, a dark shadow flashed, and then there was no movement.
