"Oh? How do you develop it?" Cao Xing's interest was piqued.
The witch slowly said, "I have seen some related records in books before."
"Extracting essence from the blood of those legendary demon creatures and combining it with some precious herbs, such as Yala Flower and Life Tree Leaves."
"Perhaps it's possible to develop a Life Secret Medicine containing strong Life Force, which could even resurrect an ordinary person."
"Besides, you can also seek materials from powerful beings, like blood and bones, using them as core ingredients for the potions and supplementing with other materials."
"It's possible to develop a Secret Medicine containing extremely strong power, granting the user special abilities temporarily."
After listening, a thoughtful look appeared in Cao Xing's eyes.
"Blood from legendary demon creatures... So we're talking about Legendary Level beasts or monsters?"
