I just posted this in the HSDS thread, but I want to bring it to other people's attention and get their opinions. I'm talking about YG discovering DG's wooden sword rotten in the sword tomb:
"Most of the top arts of DGSD must have been developed in the Tang Dynasty right? Then they must have had mad powerful greats.
Personally I think Tang is when Dugu lived. I was talking to my dad about this, and he confirmed; wood protected from the element rots, but we're talking hundreds of years, not 70-80."
