The time traveler Qi Zhe started his journey to the Qin Dynasty with a magical excavator. He not only built the Great Wall that reached directly to the Roman Empire, but also erected a towering dragon city on the Xiongnu grasslands, and thousands of ancestral dragon statues erected across the Central Plains. Faced with the First Emperor's curiosity about the overseas fairy mountains and his desire to explore the unknown world, Qi Zhe relied on his extraordinary wisdom and modern scientific and technological knowledge to help the Qin Dynasty possess an aircraft carrier on the Feilu Sea, and even planted the black dragon flag all over the world, making the Qin Dynasty powerful throughout the world and achieving unprecedented territorial expansion and civilization integration. All these miraculous achievements originated from the moment he drove the excavator on the day he first entered Xianyang!
