After sorting out the information about the new skill in his mind, Chen Xing couldn't help feeling emotional from the bottom of his heart.
Indeed, just as he had guessed before, this new skill actually required the use of three types of plant-based precious materials.
The first was the "Heavenly Silkworm Soybeans" used to make dried tofu, the second was the "Heart Devouring Chili" used to make chili oil, and the last was the "Soul-Dissolving Ghost Garlic" also used as a seasoning.
After searching online, Chen Xing found that Heavenly Silkworm Soybeans and Soul-Dissolving Ghost Garlic were directly available for sale at the Universal Commerce Association, and some other shops sold them as well.
Heart Devouring Chili was for sale at the school logistics department's warehouse.
These were not particularly rare treasures; as categorized by the Exotic Region's native division, precious materials were divided into 1-10 levels of Secret Treasures.
