After his physical examination, Linri was free to go wherever he wanted. He already knew the basic layout of the school so it shouldn't be too hard to find his way around.
While strolling around and searching for his target, he also played around with his newly acquired toy. From the looks of it aside from seeing his stats, he could also analyse his surroundings and other objects and if they were located in the pre-installed database he could learn their properties. Also if they were not in the database he could make new entries and record them. Meaning, it was basically a glorified goodle and he wouldn't be able to get any benefits from it in the short run.
