Dig a grave and dig out a nest of ants! How good or bad! Is the land still usable? Seek expert answers

It should be a treasure land, as long as there are ants in front of the grave, of course. Ants are equivalent to thousands of horses. It is not good to have a grave before there are ants. Just like a snake, dig out the snake first, and then have a grave. This is the treasure. There is a grave first, and then there is a snake. This is the real situation.
