解决方案

打开网页,有三个色块,暂时看不到其它内容。Ctrl+U查看源码,有发现:

<form action='#' method = "GET" target="resultFrame">
    Upload Your Profile Picture : <input type="file" name="profile_pic" >
    <input type="submit" value="Upload Image" name="submit">
</form>

竟然有个上传文件的表单。随便选了个文件上传,跳转到一个新页面,有个字符串:

The_scroll_says=the_night_kingVSvalyrian.txt

尝试请求the_night_kingVSvalyrian.txt:

pctf{You_L00K_Wi3Rd_IN_H3R3}
