Tang Xiu got up and came to Zhang Xinyue as he took out a jade bottle out and handed it to her. "There's a drop of the Body Tempering Liquid inside. Pour it into the hot water when you take a bath. It can improve your physique and you'll know the benefits after you use it. But keep in mind that the process can be a bit painful; try your best to endure it and soak yourself for half an hour or more."
Immediately after, Tang Xiu took out a pen and paper and quickly wrote a cultivation technique on it. It was not cultivation from the Immortal World but one of the many cultivation techniques he had obtained back when he was in Changxi City.
