The question of which one would open up the fifth world had a certain degree of controversy and different explanations in online novels. Generally speaking, the beginning of the novel," Sword Comes," was about a swordsman named Zhang Luoyang in the martial world. The tattoo was the name of a character in the novel and also a villain in the novel. It was impossible to determine which picture would open up the fifth world because there was no clear answer to this question. It might depend on the plot and setting in the novel. In different novels, the source and method of the fifth world may be different, so it is impossible to determine which picture is the most suitable.
