He woke up in the middle of the night and heard a strange noise outside the door. He went out to check and found an abyss in front of the door. Something seemed to be crawling up inside. When he looked closely, he saw that it was a bloody "corpse", which was simply too horrible to look at. Later, the "corpse" was cleaned up and taken care of by him, and it finally looked like a human being. The "corpse" said that he came specifically to see him. They had known each other a long time ago and had not seen each other for hundreds of millions of years, so they missed him very much. I always feel that some things will eventually come to light even if they are deliberately covered up. What exactly did they experience among the stars hundreds of millions of years ago? Why does he feel so sad?
