The Outer World doesn't have cloud towers like giant mushrooms, and in the Inner World, all mechanical limbs have special wireless charging technology.
Moreover, in the Inner World everyone's mechanical limbs were always charging, but once they returned to the Outer World, they only remembered about charging when the power was about to run out.
Initially, Jiang Xue's mechanical limbs, after just one high-intensity use, faced the trouble of running out of power. It was XiaoTongyun who thought up a solution by replacing them with a high-end military-grade mechanical arm to avoid such embarrassing situations in the future.
However, other Time Travelers were not as lucky as Jiang Xue...
Most Time Travelers possessed mechanical limbs of the same grade as Jiang Xue's original ones.
Quite a few Time Travelers became disabled within just seven days of returning.
Some had mechanical arms that ran out of power.
Some had mechanical legs that ran out of power.
