Traveling Back to the Warring States Period, I Want to Unify in Place of the First Emperor

Warring States, great famine. People eat each other. I came through time and space with nothing but a table. This table can turn soil into corn, corn into refined iron, and refined iron into thousands of troops. I asked the refugees, "Would you like to come with me? I can give you food to eat." I asked the ranger: "Are you willing to kill for me? I can give you magic weapons." I asked the world: "Can I be the leader of Liuhe?" The First Emperor is still in the state of Zhao as a hostage, and the world has not yet been settled. And I have started from a handful of soil and weaved a web that covers the world. ——Everything is replaceable, but I alone am the king.
