The design of this virus isn't particularly innovative; in fact, on modern-day Earth, applications more extensive than those of the medieval period were already in use, with the most famous being Tutankhamun's Tomb.
Tutankhamun's Tomb, predating the anno Domini era, belonged to Pharaoh Tutankhamun of the Ancient Egypt 18th Dynasty and is hailed as one of the world's top ten ancient tombs and rare treasures. Its discovery once shocked the entire world.
During the excavation of Tutankhamun's Tomb, many precious relics were removed, such as the golden mask, burial artifacts, and the mummy itself, which caused great excitement among the world of cultural relics. However, it was fearsome that those involved in the excavation began to die one after another following the removal of these items; some visiting archaeologists also succumbed to illnesses in succession, even collectors who had brief contact with the artifacts could not escape a ghastly fate.
