Three days before he was reborn into the reality of "Dawn of Doom", Chen Han spent one billion of his wealth on krypton gold like crazy. He activated the hidden profession of SSS-level swordsman and emptied the trading place of all resources. The gold digger who betrayed him in his previous life and the rich man who plotted against him are now proud of his "stupidity".
When the end of the world truly comes, zombies and mutant beasts run rampant, and resources become the key to survival. People who once ridiculed him struggled to survive in despair, but Chen Han relied on advanced layout to establish a huge survivor base, monopolize material transactions, and control the lifeblood of the city.
With the emergence of mysterious ruins and the rise of new forces, Chen Han continues to encounter new challenges and crises in the process of exploring the truth of the doomsday. From a ridiculed "wrong" to the ruler of the doomsday world, how will he use the power of krypton gold to write his own legend?
