Steve felt that it was ridiculous to search for the mammoth cemetery by simply going around, staying on the earth's surface. The carcasses of the mammoths would be hidden underground. There would not be any sign of them on the face of the earth.
Had it been otherwise, the work of the mammoth ivory hunters would not be so difficult. They would not need several months to find ivory.
Li Du said, "Then you come up with another solution. How would we be able to find the ivory more effectively?"
The ivory hunters had a tough job. Based on their experience, they would decide whether an area might have mammoth remains. Then, they would start to excavate heavily all around, searching for the mammoth skeletons.
Hence, their job would severely damage the environment of the taiga.
