After the Li family surrendered, Li Hanzo was captured and the attached machines were all removed from his body. His mechanical augmentations were also shut down with a special method of the Truth Guild. In the power system of this sci-fi world, an individual gained strength by training their body to be able to withstand special augmentation done with a special material called Xenopherus. Anyone who could withstand more augmentation of this kind could grow super strong very quickly.
Other than that, replacing various body parts with various machines was also a way to grow stronger in this world. Li Hanzo had used both of these methods but the Truth Guild had ways to disable both.
