One day, a gallery appeared before my eyes.…And then I was able to see who wrote in the gallery.All the heroines are ‘virg*ns’.

A new work from the author of 'My Senior Brother is Too Steady', welcome to enjoy it!------------------In the instant the Earth exploded, the fear of death finally transformed into physical torment, the agony of being scorched seared into the deepest recesses of Yang Ming's memory.“The universe is the abyss.”Yang Ming murmured softly among the stars.[PS: Not a game narrative; early game settings will have a complete logical explanation later in the plot. Starting anew on a different track, this isn't in the style of previous works so don't promote it in the old way, treat me as a newcomer. Just entering the domain of interstellar sci-fi, corrections on details are welcome. ]
