Checking page 2

Page 1 looks good, so now I need to check out page 2. I want to make sure everything flows as expected, especially with how the sections and table are placed. Just need to verify how the content looks and whether any further adjustments are necessary for smooth transitions.

已完成计算并整理成文档。

第 1 轮输出为： {C43311D3, B826F4B4, 94B93A17, 4BB7366B}

逆向解密恢复的明文为： {01234567, 89ABCDEF, FEDCBA98, 76543210}
