Sylvester gave the CPR for more than a dozen minutes and kept trying to heal her simultaneously, so her body would get out of the initial injury shock. The blood replenishing potions were also given to her, by force this time. At the same time, he used healing lotions for flesh wounds and put them on her chest while giving chest compressions.
"Ha!"
"Ha!"
He stopped giving compressions and trying to hear her heartbeat. "Yes!"
It was very faint, but it was there. She was alive, and all he needed to do was make sure she only got better. "Chonky, good job. Now sanitise your hands with the alcohol and give me the tools as I will ask. I need to perform minor surgery on her chest to sew a few wounds and heal the others."
