Late at night, the regent Shen Yan, who was poisoned and hunted by political enemies, forced his way into Jishi Hall.
He put the blood-stained knife on the side of Xu Qingrou's neck and threatened her to rescue her. On the surface, Xu Qingrou was trembling with fear and tears came to her eyes, but in fact, when applying the needle and bandage, she secretly planted a "child-mother poison" in Shen Yan's body - this poison could suppress his old disease, but it also made him unable to do without her unique antidote in the future.
*"Your Majesty, this little girl is timid. If this needle sticks crookedly... You will be useless."*
