The surgery on the male super species was successful.
It had many things to do with the creature’s natural tenacity. Even after such serious blood loss, when he was administered the nutrient potion, his circulatory system came alive, producing new blood. Even though the blood produced could still rival the blood loss, at least the beast was slightly more conscious. This way, the medical crew could work without fear of being hurt accidentally.
The surgery was simply the removal of the rotten muscles and suturing the wounds. The main issue was that the muscle of the super species was too tough, so normal surgical knife couldn’t cut through it. Eventually, they had to use a laser equipment to sever the atrophied muscles.
