After Red Tide

In this plane, when tens of millions of troops were invested, the "Great Red Tide" that swept the world for the great ideal ended in a global nuclear war. In the shelter under the wasteland, the powerful matrix core was still calculating and executing the initial and final plan. As a time traveler, Jonghyun is a young man with a calm temperament who has been living in a shelter for three years. He learns the truth when he is about to die and is involved in a huge plan about human nature, ideals and conflicts of interest. Trapped between ideals and reality, between necessary evil and fairness and justice, when the Federation, regarded as the 'root of all evil', re-emerges in the wasteland and is about to take over the world again, Jonghyun must make a decision.
