As for the newly-joined itka ratfolk tribe, the reason they could receive such preferential treatment was actually because of their extraordinary magic talent!
Through his previous observations, Xu Nan had long determined that this ratfolk tribe had a rare talent in magic under the radiation of the green gem Mine for many years.The group evolution under Zura's guidance was only a small part of these talents, as they had greater potential.
The ratfolk loved to take risks, but they were also curious about exploring the truth. What Xu Nan wanted was to stimulate the ratfolk's heart to explore. His real goal was to cultivate a group of practical and capable alchemy confidants.
