Egypt, located in the Nile Valley, has a geographical advantage, and the Egyptian people have established a splendid civilization along the Great Nile. Extremely rich Egypt even affected Europe, which was still in its infancy at that time. This splendid civilization is based on slavery. As long as war is waged, there will be endless slaves to use. This made the luxurious Egyptian pharaohs extremely luxurious in their post-death architecture.
According to the existing data and documents, to build an ordinary pyramid, you must eat nearly a quarter of the wealth of the Egyptian empire. At the same time, countless slaves will die of fatigue, and many scientists are puzzled by the difficulty of construction, and even once thought that aliens helped them.
However, this does not mean that the pyramids are more difficult to build than the Qin tombs! In terms of comprehensive national strength, the Qin Empire, which ruled the Central Plains, was strong and even surpassed the extremely poor Roman Empire in terms of resources. In the construction industry, most of them are elites from the battlefield, plus workers who have already worked in the Great Wall. Such a lineup can create such a miracle. In fact, if you compare some traces excavated in Xi 'an today, you will find that the pyramids can't be compared with the Qin Tombs!
