Body Tempering Liquid, this substance, had already been prepared within the village three to four months earlier. Of course, the Body Tempering Liquid they had was made from the blood of wild wolves, and its effects were unknown how much weaker than that of Flood Dragon Blood.
After Wang Sheng first used the Body Tempering Liquid concocted with Evil Flood Dragon Blood and Spiritual Medicine, he continued to use it several times, advancing the progress of the Yijin Scripture almost to the brink of a second Breakthrough. After that, it wasn't of much use to him, so he gave it to the villagers to use.
However, progress in anything should be gradual, and the Body Tempering Liquid made from the blood of wild wolves was just right for the children of the village.
The Body Tempering Liquid made from Evil Flood Dragon Blood was indeed potent, but it was not suitable for the children of the village who were not martial artists.
