The three-headed giant tortoise was not too strong, but on this black grassland, it was definitely at the Overlord level.
Not only was its back and abdomen covered in bone armor, but even its eyelids were covered in tiny scales.
Even if it was slashed by knives and shot by arrows, it would not be able to cause any serious damage. It could not even be considered a light injury.
If one wanted to kill it, they would need to be skillful. There was no use in using brute force.
The three-headed giant tortoise did not move at all as it looked at the monster that was charging over menacingly. Its eyes flashed with a trace of contempt.
Perhaps in the eyes of the three-headed turtle, these monsters that were charging at it were just food that was sent to their deaths.
However, the three-headed giant tortoise had just eaten its fill and was too lazy to eat. Hence, it retracted its head and feet back into its shell and went to sleep without restraint.
