Have a great hunt agent X,

P.S.
We, also, were able to retrieve this:

I’m sure that with your capabilities you can solve it.

暂时看不出来是什么,我试了下XOR,无果
然后就尝试附件

是base85
在这边,在那边,在那阴森的岩石上,
我看见长着角的魔鬼,手里拿着巨大的鞭子,
在后面残忍地鞭打着他们。
这段文字出自但丁的《神曲》中的《地狱篇》,具体是第十八篇的几行诗句。
后面扒拉了很久
然后终于发现了

是base64
解出

然后搜索dante's inferno cipher(从附件中得知的信息)
你能找到这篇文章
https://bitvijays.github.io/Series_Capture_The_Flag/LFC-Cryptography.html#esoteric-programming-language
所以我搜索了一下这种编程
找到这个
一运行
10:11:2023:14:00
得到一个时间
然后就往前推了,找那个图片的信息
勉强恢复了一下
直接google无果
看能不能通过时间反推吧
(尝试了很久,没有结果,暂时搁置)
