I have read this manga for a while now (possibly more than 3 months). The main character was reincarnated into another world in which he (she in this case) lives in the forest and has almost no interaction with other human.
She has the power to create (more like synthesize) things from his past life which in turn, makes for her a movable house in the wood. Then she was met by villager begging for help for the disease so she create a medicine for them for free.
However, some people in the village then come and ask for her help again but this time coerce her to give them a free medicine (and with the mob of villagers in the end). She then moves her house out and the first pair of villagers who were asking about the medicine regretted their actions. This story also has a comedic part where Main Character accidentally gained ecchi skill when she looks at herself (and synthesize garments for herself).
