Yuki went to the border of the desert while thinking that she could just buy the flower from the shop but after she claimed the cliff, her conscience was not allowing her to do it.
One more thing was she didn't know where those items in the system were coming from, even in that sense she didn't want to use the shop very often.
'Life is not about the destination, it's about the process,' she thought to make up her mind to not buy the flower from the shop.
'Everyone's destination will be death, so of course, the process should be important,' the system explained to strengthen her resolve, 'but most civilizations became goal orientated and as the people are doing a wrong process they are miserable most of the time.'
The wrong process meant the people were not enjoying the process, which they were not accustomed to.
