The content of the third diary entry is very concentrated, with the entire focus on research.
An entire month had passed between the second and third diary entries. Over such a long time, the mentality of the researcher who wrote this diary had noticeably changed. He no longer fixated on anything else, his sole desire now was to complete the research as quickly as possible, because only by doing so could everyone survive.
However, from the latter half of the diary, it seemed that although the research was progressing relatively smoothly, it had encountered an unexpected difficulty— a shortage of supplies.
