Besides this,
there was something even more precious, which was the chip currently inserted into the Train Assistance AI.
"Train Captain."
Inside the train compartment, Ai's cold and mechanical electronic voice sounded: "This chip contains a lot of data and information about mecha modification and manufacturing. There are many tools and materials here; after gathering them, I can modify and upgrade the mecha within the train in the future."
"Including those instruments, some are for testing plate armor data and rating, such as Level 4 defense or Level 3 defense."
"Some are mecha space compression instruments, able to compress a mecha to roughly the size of a suitcase."
"The circuits of these instruments can all be connected to a generator. There should be an Energy Stone here, and it isn't low-level, otherwise, it wouldn't be possible to support this laboratory on standby for so long."
This chip was something they just found, specifically in this laboratory.
