Mo Tang and Mo Sheng fixed their gazes with grave expressions.
Before long, Mo Yunchen's chest began to burn with heat. He knew it was time to extract his Heart Blood. Mo Tang passed the knife to Mo Yunchen, who took the slender knife, and a flash of cold light passed by. Mo Yunchen let out a stifled groan, closed his eyes, and fine sweat beaded on his forehead. His right hand turned slightly, and the blood drained from his face gradually, turning pale. Aside from that first muffled groan, Mo Yunchen did not make another sound.
Mo Sheng and Mo Tang could hardly bear to watch this scene. Their fists clenched tightly, wanting to persuade Master Mo to stop, yet knowing that Mo Yunchen would definitely not give up.
Mo Tang's brows were tightly knit as she handed the glass tube to Mo Yunchen. He inserted the glass tube into his heart, the sharp Silver Needle piercing through his heart, and droplet by droplet, the Heart Blood flowed into the glass tube.
