Li Goudan was a person who loved to join in the fun. Naturally, she would not miss out on the exploration of the map of Gondolin. There, she had seen some lords who were reluctant to undergo genetic surgery, causing soldiers to mutate.
This was related to the cost. It was difficult for soldiers to avoid fighting with the local mutated creatures when exploring the map. The more battles they fought, the more alchemy energy they absorbed. And that energy was very complicated, in addition to the pure energy produced by the creatures themselves, there were also the complex mutations of genes and elements. Therefore, the soldiers who stayed there for a long time would mutate.
