The experimental story world was created by Dreadful Radio for the sake of experimenting the procedures of a team, making amendments to any loopholes. That was why the story world was inevitably a little blunt, everything was not done for the sake of the plot but for the sake of the data. Perhaps Dreadful Radio felt that it had collected enough data, the three people who were stronger than other audiences by leaps and bounds were either injured or dead and had no way of cleaning up the whole situation, it might as well sent Noah's Ark down to suppress it putting a full stop to this story world.
Su Bai had not recovered from the fact Lan Lin had fallen, after running up and down, he realized the story world had actually ended.
Three hours actually passed very quickly. After Su Bai strangled the kitten to death, he just sat by the riverbank, he did not seek out any audiences, nor did any audiences seek him out.
