Midnight chat

I opened the video call window that I had started, and it confirmed to me that the call had indeed been disconnected, and the small green circle light next to his name and picture on the screen went out, indicating that his device was no longer connected to the internet. But I found a text message from him in the written messages section, which showed me that he had sent it minutes before the disconnection. I began to read what was written: "Now that I have known what I am aiming at, O Saif, here is a conclusive proof of the development of algebraic sciences among the ancient Egyptians. I am confident that dozens of questions will haunt you now."
