As a professional doctor, she could generally determine the specific location of the infection source.
Through analysis, most of the infections were among the ranch workers.
Therefore, the source of infection was definitely not inside the office building.
She quickly walked out of the office building and into the factory area.
It was still early; the workers hadn't come to work, and no one stopped her, so she proceeded straight ahead.
She took out her phone and started photographing the scenes she passed by.
Water sources, milk sources, equipment and machinery in various workshops, as well as the operational counters, warehouses, and production workshops, these were all places likely to be infected, and she took pictures of them one by one.
She wanted to collect some samples to take back for testing.
But conditions didn't allow it, so after she finished filming the factory, she also took some photos of the ranch.
