Wu Laika inexplicably entered a book and became the hero's younger brother. As for why he knew it was a book, it was because the plot was all in his mind...
But these are not important. He was bored in his original world, but maybe it might be more interesting in another world now...
So the lonely prairie king has a younger brother beside him, who will accompany him when he falls into the trough and stand with him at the top...
Wu Laika is cold, ruthless and scumbag. He does everything for fun. He stays with his brother because his brother is the protagonist. Interesting things will happen when he stays by his side. He will not take action unless necessary...
Being pursued and attacked, being favored and attacked, being abused but not attacked
Not a biological brother
Purpose: Imaginative essay
