Immortal Zunsheng: I Hand over Heaven to the Country

The survivor of the great catastrophe, the greatest swordsman in heaven, was reborn in the new century of Blue Star. What can I do if I have magical powers? Of course, it must be handed over to the state! Can you go to heaven and earth? But can you have an iron rice bowl? Do you have ten thousand swords to return to your clan? But can you prepare it? Can you live forever? Then you will work for others for the rest of your life! Do you know how valuable the system is? So the task of rebuilding Heaven fell on an ordinary high school student.
