Da Qin: Beginning

In 221 BC, the Qin Dynasty unified the world. Zhou Qi, an engineer from the 21st century, was reborn in Xianyang Broken Blacksmith with a black box of advanced civilization. The black box hides cross-era technology, but it also leaks the earth's coordinates to the universe. He used the blacksmith shop as a starting point to recast the Great Qin war machine, build a galactic defense line, and face the interstellar visitors from 87 years later. He used a furnace of molten iron to illuminate the entire universe.
