Su Yunjin, having lost hope, traded her mother's hairpin three days ago for a pack of arsenic.]...Arsenic!Staring at the hot porridge brought to his lips, Chen Jie looks up at his wife, seeing the faint bruise on her face and her eyes shifting away, avoiding his gaze.“Honey!”“Yes?”“You're not going to kill me, are you?!”

Thanks to the Goddess, he was reincarnated into nobility!　That should have been great―― but the skill he got, 【Toxin Decomposition EX】 was simply too plain, and he was made fun of everyday at home……
