What does the ending of "Prison" mean? Are Blade and Spike dead? What are you laughing at? He lives alone?

Prison of the Demon Ship is a novel. Due to the different versions and translations, the ending may be different. However, according to the version I know, the ending means:

Blade and spike are dead. At the end of the novel, Blade is executed, while Spike is in a coma because of serious injuries. In the end, Blade completed his life journey with the company of "brothers".

Xiao Bai did not die in the novel, but his future was not clearly described. According to some hints in the novel, Xiao Bai may continue to live alone and pursue his dreams.

In a word, this ending is tragic, and the main characters have experienced different pains and hardships.
