In Alex's previous life, he never really had time to think about the aim of these challenges. He was too busy fighting and training to vent the anger he felt because of his family's death. But now that he had the chance to repeat these challenges of the apocalypse, Alex began to question the purpose of the Doomsday Pillars in coming to the world.
The battle of the first challenge was against wild beasts such as wolves and bears in the middle of the forest. The fighters were given very little information against these beasts. This challenge's aim was to test the mental stability and strength, as well as the courage of each fighter.
Meanwhile, the second challenge was a group challenge. They had to go against an armed enemy that required solidarity and a battle strategy to deal with it. It was considerably more difficult compared to simply killing wild beasts.
