Bab 158: Fingerprints

"Let's get on with this," Liu Hui Ying asked Yu Lingyun to place the sword that he has brought with him on the study table, now she was going to make an imprint of the fingerprints that were left on the blades and the handle of the sword since this world did not have the fine dusting powder and the fine dusting brushes that were used by the experts. Unlike her who had both regular and magnetic powder to detect the fingerprints sticking on the surface of the sword. 

Seeing that she was starting with the investigation, Yu Lingyun turned to look at Zhai Heng and tugged on his sleeve as he said, " Do something, she is starting her work. His majesty asked us to not start until he returns, he will be really unhappy if he was to come and find that we are already on the third step."
