Grave robbers mainly rely on digging holes. This stolen hole looks simple, but there are many doorways in it. How to accurately dig into the tomb and how to ensure that the pyramid-shaped mound does not collapse are all exquisite.
At the earliest time, experts were also curious about this, because in a vast position, it is tantamount to finding a needle in a haystack to hit a stolen hole into an ancient tomb. Therefore, experts have studied a large number of stolen holes to find out the principle.
We also pay attention to stealing holes, not round ones. If the stolen hole is round and lacks the support of the surrounding soil layer, it will collapse. Therefore, the holes stolen by grave robbers are generally square, and it is more convenient to play with a ladder that goes straight up and down.
Ancient tomb raiding groups, their means of tomb raiding, are very clever. They often find ancient tombs before archaeologists. Why? This is because there are too many people in their group. Then, using their clever secret means, they accurately found the position of the wood and made a hole above the tomb, which was very accurate.
