With the mechanical arm, it is not all good for Chu Jungui. All loadable components need to be recompiled to accommodate the new robotic arm version. This is just fine-tuning and requires much less computing power than a full compilation, but also takes a day or two.
The new robotic arm also has unique capabilities. In the case of auxiliary power, it does not require a lot of muscles like the bionic arm, so there is a lot of internal space to use, and the upgradeability and diversity are quite outstanding.
Even with the current simple conditions, Li Ruobai can create a combination of swords and shields, so that Chu Jungui has an extra set of melee weapons. Li Ruobai also built a simple shotgun inside, which specially fired shotguns soaked in interfering radiation to deal with girls in white skirts.
