Everyone knew that Wang Yun had an excellent memory. But Ji Zi'ang was a little confused. "Normally, such structural drawings are an esoteric subject, so how did you come to learn all this? It has nothing to do with your previous job scope."
Wang Yun explained to everyone, "When I realized I had a photographic memory, I deliberately spent some time reading in the library. I've been to public and military libraries. This way, I don't have to flip through books when I need the information. I can just retrieve it from my mind."
Then Wang Yun drew a series of three-dimensional structural designs, such as foxholes, trenches, and other structures from his memory. These would then be used for Ji Zi'ang's reference.
Wang Yun said, "There will definitely be some differences between the drawings and what is actually built. But with Ji Zi'ang's power, they can be adjusted accordingly after they're built, so it's not a big problem."
