I Build an Empire in the Last Days

When the apocalypse broke out, Lu Feng, who went from dying on the streets to being reincarnated, wanted to lie down and develop, but reality did not allow it, so he had to reluctantly pave the way. What to do if there is no material? There was a pile of ruins in front of him. He waved his hand over the ruins and turned them into pieces of materials, such as earth, cement, iron, copper, and wood! I'm going! It's not a superpower, it just makes me a god! Zombies? The end of the world? I, Lu Feng, am here!
