In 20XX, human civilization reached its peak, and a holographic competitive game called "Power War" became popular all over the world - players obtained three types of abilities: weapons, professions, and mounts by drawing "power cards", and competed as a team in the virtual battlefield. The card levels were divided into C, B, A, S, SS, and SSS from low to high. The higher the level, the stronger and rarer the ability.
No one knows that the core data of "War of Superpowers" comes from the "Energy Civilization" in outer space. When the earth's magnetic field fluctuates abnormally, the "realization program" of the source energy civilization is accidentally activated, and the monsters and card rules in the game come to reality - the city collapses, game monsters named "Bone Eroder" and "Shadow Pattern Spider" are rampant, and humans are forcibly involved in the "real power battlefield". Each person can only draw 3 power cards at the beginning. Survival or death depends entirely on cards and wisdom.
After the end of the world, humans have formed scattered survival bases, and cards have become hard currency. High-level card holders have power, while those who have not drawn combat cards are reduced to the bottom, struggling under the threat of monsters and similar types.
