The safe didn't contain any valuables, just a paper document inside a kraft paper bag, which Ye Wudao took out to look at. His face first lit up with joy, then was overtaken by anger.
As expected, Zhao Xiaodie's disappearance was related to the Matsuno Group, because this document mentioned something about "Angel No. 1" several times. Even though the document didn't mention Zhao Xiaodie's name, there was an address inside that was sufficient for Ye Wudao.
Ye Wudao put away the document. He didn't bother searching any further and slipped out the way he had come, returning to the hotel on Gong Island, where he showed the document to Zhao Xiaoman.
Since many parts of the document involved R&D jargon, Ye Wudao wasn't very familiar with them, but Zhao Xiaoman, after reading the document, immediately confirmed Ye Wudao's suspicions; all the techniques used in the document were from her sister Zhao Xiaodie's own hands.
