The development difficulty of the Animal Encouragement Talisman was far greater than that of the Muscle Relaxation Talisman by more than an order of magnitude.
After testing the encouragement strength of the Animal Encouragement Talisman, Jiang Cheng still needed to select an appropriate "reusable base" as the carrier for painting reusable talismans.
Fortunately, the talisman industry in the Cultivation World was quite developed, and these "base materials" had been tested by others long ago.
Jiang Cheng only needed to specify the parameters, purchase a few materials he needed, and then conduct more experiments.
Even so, it was not easy.
However, compared to the task reward of 20,000 Spirit Stones, this bit of hardship was nothing.
On the 8th of July, after just over a week of intensive development, Jiang Cheng finally completed the upgrade and transformation of the "Reusable Fluorescent Talisman"!
