1st of all, download this app from my dropbox: 解码工具

2ndly, plug your device to a PC, copy the valkyrie crusade card folder into the PC.

(I guess you guys already know where to get the card files, for my case, I'm using Samsung device, the destination of the card folder should be under Android\data\com.nubee.valkyriecrusade\files\card, and here you'll see thumb, sd, md, and hd folder. thumb=icons, sd=standard resolution, md=high resolution, hd=high defination, note that files hd folder only appear the cards you had open the card in full screen inside the game itself.)

3rdly, extract and run WindowsFormsApplication2.exe>select the card folder you just copied into PC>click the 解码 button (it's in Chinese, but there's only one button)>wait for popup notification and you're done!
