"That's right."
Xu Jing's lips curled slightly as she said, "This is called cooling oil."
She noticed that since Cheng Xianbai entered, he had been scratching a spot on the left side of his face with his fingers. As they approached, Xu Jing saw clearly that Cheng Xianbai's left cheek had been bitten by some insect, leaving a large swelling.
It's still summer now, the peak season for mosquitoes and other insects, so being bitten is quite normal.
Some people are particularly prone to insect bites, and by the end of the summer, there isn't a single patch of unblemished skin on their bodies.
Most people use sachets to repel insects, but sachets have limited effectiveness and can't completely keep all insects away. Occasionally, they still manage to get a few bites through gaps.
Xu Jing picked up a jar of cooling oil and handed it to Cheng Xianbai, smiling slightly, "Use your finger to apply a bit of the oil to the place where you were bitten by the insect on your face and see."
