"Twenty-first-century common experimental equipment... early experimental animals..." Xiang Shan quickly scanned the nearest collectibles to his desk, recognizing their origins.
For some, he still had the corresponding "knowledge" and knew roughly what they were. Among these "antiques," the more outlandish items would likely be the laboratory refrigerators, sterilization cabinets, test tubes of various sizes, crucibles...
Honestly, Xiang Shan really didn't understand why those items could also become antiques—they were all products of industrialization, mass production! What's the difference between "used by the Martial Ancestor" and "bought from a lab supply store"?
Besides, it was unlikely they were actually used by him.
Primarily because, he was mostly dedicated to "project management" and seldom actually conducted experiments himself.
Moreover, he generally didn't need to hold test tubes, crucibles, beakers, and the like.
