Ancient Egypt in 2480 BC was the early period of King Khufu's rule. Like every Pharaoh, he was ready to build a tomb when he ascended the throne a hundred years later. So, every summer, members of the royal family traveled all over the Nile Valley, selected strong men from each village as laborers, and built the Great Pyramid to serve the king.

They work in large groups of 654.38+10,000 people, and each large group has to work for three months. There are slaves among these workers, but there are also many ordinary farmers and craftsmen. Slaves in ancient Egypt transported huge stones to construction sites with the help of animal power and rolling logs. They also piled the sand from Zhou Tianran on the slope and pulled the boulder to the front of the pyramid along the slope.

In this way, a layer of slopes and stones are piled up, and the pyramid is gradually increased. It took about 30 years to build pyramid of khufu. The Nile regularly floods every year, flooding the land, nourishing the soil, making the cultivated land fertile and agriculture developed. Therefore, Egypt became one of the earliest countries in history that did not need to put all the labor force into agricultural production. The surplus labor can be used for other purposes, such as building pyramids.

This big ship full of labor will wind up along the Nile, passing through cliffs and fields on both sides along the way, and its destination is Giza, south of Cairo 10 km. According to Egyptian mythology, everything is a chaotic liquid at the beginning, and the first dry soil in chaos is in the shape of a pyramid, symbolizing life.

But the ancient Egyptians, driven by some impulse, chose this shape symbolizing life to build the resting place of the dead. The newly appointed Pharaoh Khufu also came to the desert with the same impulse to witness the first and most important ceremony of his reign. Stability is the key for such a huge building.

The architect plans to use giant marble blocks, which are arranged layer by layer in a decreasing way, which is the most stable structure. After the site is selected, it shall be cleaned and leveled first, and then the foundation shall be laid by skilled masons. A large square marble floor will be the core of the pyramid.

Pyramid uses:

In addition to possible tombs and observatories, one of the uses of the Egyptian pyramids may be grain depots. The results of the first step of the "scanning pyramid" plan announced in 2065438+0516543810 show that,

Most of the stones in pyramid of khufu thermal image are blue or green (indicating relatively low temperature), and only a few stones at the bottom are red (indicating relatively high temperature). This means that the temperature of the "red" stone is 6 degrees Celsius higher than that of the adjacent stone.
