In the Last Days, I Will Hand over the System of Cultivating Immortals to the State

[The end of the world + cultivating immortality + handing over system + no harem] In the zombie apocalypse, my system of cultivating immortals allowed me to enlighten my spiritual roots and lead everyone to ascend. Foreign countries are building individual heroes, but I am organizing and building a collective foundation. While the saviors of other countries are still fighting for a piece of bread, my flying sword has achieved mass production. Overseas spies sneaked in and saw the missiles engraved with runes on the assembly line, and the organized Golden Elixir monks completely collapsed. "They call this a developing country?!" But I just calmly connected to the high command: "Report to the leader, Dongfeng Express, the enchantment is completed, request for launch!"
