Fan Xian's reaction was fast enough. Shooting out like a shadow, he pushed the Eldest Princess to the ground. Striking out like the wind, in an instant he had used zhenqi to seal the important meridians near the wound. However, he saw faint black lines were already slowly enveloping her bright face.
This black dagger had been in Li Yunrui's abdomen for a while. It had simply been hidden by the wide sleeves. What shocked him even more was that the Eldest Princess had pushed the dagger into herself but was able to talk to him freely, without revealing a glimmer of pain and successfully hiding it from him.
The poison had already flowed around her body with her blood. It had entered her heart and risen faintly into her face. Even if Fei Jie appeared in Jingdou right now, he still wouldn't be able to save her life.
