The intense itching over his body was, in fact, even more unbearable than severe pain.
But the most frustrating part was that Gao Yuan was a prime example of non-humanity: medicines that were effective for humans barely worked on him.
Those acting on the nerves, those that blocked the senses, any medicine had no effect on Gao Yuan, even in increased dosages.
If he didn't inject the monster's blood plasma, Gao Yuan's body wouldn't feel so uncomfortable, at least not too itchy, but then the healing process would slow down.
Adopting the philosophy that prolonged pain or itch was worse than short-term agony, Gao Yuan signaled for the blood transfusion to continue.
Anything, whether unbearable itching or severe pain, after becoming familiar with the sensation, would numb a person, which was an increase in tolerance.
Although Gao Yuan still occasionally thought it would be better to be dead, his days had ultimately become a bit more bearable.
