The End of the World: I Rely on Binding the Valkyrie to Survive

The end is coming. The monster named "Beast" and the virus released from it. Put humans who have not yet reacted in a desperate situation of extinction. The remaining humans established a federation and frantically developed technology. And created the humanoid killer weapon - Valkyrie. This slowed down the rate of human extinction and allowed us to take a breather. But Chen Moran suddenly traveled to this doomsday world game and obtained the Valkyrie binding system. Any Valkyrie bound by him can be strengthened qualitatively. [Bind A-level Valkyrie, gain 50 attribute points] [Bind S-level Valkyrie, gain 200 attribute points] … A steady stream of Valkyrie warriors. New and expanded bases are constantly being added. Chen Moran finally lived the happy life he dreamed of in the last days. If that's okay... I actually want to get a few more Valkyries.
