…

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.

…

The emaciated old man with an alien-like appearance grinned maliciously, while the young girl cried and howled.“Worm, worm, worm, worm, worm, worm...”Countless worms surged towards the girl like a tide, seemingly intent on devouring her completely.The girl instinctively closed her eyes and let out a desperate wail.“Someone... save me!”A breathtaking beam of light cut through the dimness, dispelling the girl's fear and the swarm of worms that filled her vision. Accompanied by a voice that was young but carried a hint of sunshine.“It's okay, I'm here. Big brother is here to protect you.”The boy with purple hair and purple eyes held a scythe in his hand, blocking in front of the girl, and issued a declaration of death to the old man.“You deserve to die, Zouken Matou. No, Makiri Zolgen!”
