Disasters are coming, civilization collapses, ferocious beasts are rampant, and resources are reduced to survival chips. This is a dark era when everyone is in danger! I, {Lu Chen}, was once an elite in the business world, but was reduced to a lamb to be slaughtered in the disaster - until the [All Things Exchange System] was activated! You can exchange scrap metal for food, gravel for weapons, and you can even exchange the enemy's maliciousness for super-powerful technology! Faced with the covetousness of predators and the siege of ferocious beasts, are former business rivals making trouble? Sorry, elite mind + heaven-defying system, I not only want to live, but also live the most nourishing life! Establish a safe zone, gather survivors, and use the exchanged technology to crush everything! Who says you can only survive in dark times? Look at me, Lu Chen, using the system as my blade and the wisdom of elites as my strategy, I will build my eternal empire on the wasteland!
