Having transmigrated from that technologically advanced world, Song Qingshu was no doctor, but through exposure he had picked up more or less some basic medical knowledge. Once a person's body temperature exceeded forty degrees, they could easily fall unconscious or suffer convulsions. And once unconsciousness and convulsions set in, even if they were cured afterward, irreversible brain damage and lasting complications could easily remain.

"Even if the doctor came, he probably wouldn't have any good solution," Song Qingshu said bluntly. In later generations, people endlessly debated whether traditional Chinese medicine was useful, but whether they criticized or supported it, they would likely agree on one thing: herbal medicine worked relatively slowly. By the time the doctor arrived, wrote a prescription, the medicine was brewed, drunk, and finally took effect, the flowers would have withered long ago.
After thinking for a moment, Song Qingshu said, "For now, we can only use physical cooling to bring down your temperature first."
"Physical cooling?" Lu Wushuang looked utterly lost. "What does physical cooling mean?"

Before he could finish, Lu Wushuang asked curiously, "If we're trying to cool me down, why use warm water instead of cold water? Wouldn't cold water cool me faster?"
Song Qingshu shook his head and explained, "Cold water differs too much from the skin's temperature. It would stimulate the skin and cause the pores and blood vessels to contract, trapping the heat inside the body. Not only would it fail to lower your temperature, it
