Night had fallen, and in the laboratory, an old man herded the teachers and students home like a shepherd driving sheep.
For most teachers and students, every minute and second they could spend on experiments was precious. In fact, many were aware that even if they were to enter a different lab in the future, where seniority mattered, the opportunities to participate in experiments would be scarce, and who knew how many years one might have to serve as an assistant.
And for more students, they would enter industries only slightly related to their majors, gradually returning all knowledge unrelated to work back to the university.
Therefore, each minute and second they could spend with these high-end instruments was to be cherished.
