In the "Great Fission" era after the Third World War, retired special forces soldier Lu Zheng accidentally crashed into the restricted area of the South Pacific - "Helios Island" while performing his last airborne mission. On this isolated island that was erased from satellite maps, he encountered a one-eyed mutant wolf with almost human intelligence. What's even weirder is that the wolf's reaction pattern and tactical movements are exactly the same as those of his brother, Lu Ming, the former chief combat tester of the "Helios" biochemical agency who has been missing for eight years. As the struggle for survival progressed, Lu Zheng gradually discovered that his brother was not dead, but "living" in the body of the wolf in another form. And the secret of this island is far more terrifying than a biochemical experiment.
