The technological gap is truly frustrating. Even if you know exactly how something works, without the right equipment, proving it might take ten to a hundred times the effort—it's almost like using a 20-centimeter ruler to measure the length of a train, while someone else uses a laser rangefinder and gets the result simply by pointing it from the train's head to tail.
Fortunately, for Boss Yan, things like advanced equipment have never been much of a problem for him. Plus, many of the materials here are temporarily of little use to him.
By around 11:00 PM, Professor Carter and Professor Hans finally wrapped up their work for the day. Originally, Carter intended to arrange for them to stay in the laboratory dormitory, but Professor Hans insisted he needed to go back, as he had some tasks at school to handle in the morning before coming over again.
Likewise, Yan Fei wasn't too keen on staying there either. Sure, the lab was top-notch, but how good could the dormitories be?
