Sweet uncle

But Fu Sheng doesn't let go of her throat. Instead, his fingers become tighter. Li Dai Yu struggles, slapping his hand, and grunting in pain until she loses her consciousness. Fu Sheng holds her in his arms, watching her with pain. He hugs her to his chest and closes his eyes. A tear drops on her hair. Fu Sheng exhales as his heart constricts in pain. 

"I am sorry." Apologies cannot bring back his Huang Qiuyan. Whether she will ever come back or not, he doesn't know it. She's been waiting for him and he failed to come back in time. Li Dai Yu was right. He didn't take her as his priority. 

He covers her with his coat. He can't bear to look at her wounds. He realizes the problem. While her magic is growing at an alarming speed, her body can't cope with it. It's dying. Her healing ability is slowing down.
