End of the world + rebirth + stockpiling + cool story + infinite space + system + no saint + gene warrior + revenge + single female protagonist

The sixth ice age came suddenly, global temperatures dropped by 100 degrees, and large-scale human deaths occurred.

Ling Feng, who was brutally murdered by his relatives in the apocalypse, was reborn three months before the apocalypse. He awakened the space replication system, and all materials collected into the space could be replicated a hundredfold, or upgraded a hundredfold.

Ling Feng used the tens of billions of funds in his hands to frantically stock up on goods. Lack of supplies? That's impossible!

After the money was spent, he bought a storage center worth tens of billions for zero yuan. Through the replication system, he had trillions of supplies in his hands, surpassing the rest of the world!

In terms of security, he built a safe house that can withstand nuclear bombs!

In terms of military power, he has a genetic serum that can kill his opponents instantly!

Ling Feng: The end of the world? This is heaven, okay!
