The ranking of these mutated animals were made by the scientist based on the real situation out there. Thus, if they wanted to say it, it would be easy to say that these scientists were constantly repairing their ranking.
The rank 3 mutated animals before didn't include this specification.
But now, it had changed.
"For example, among the mutated animals that we met not long ago, we found a very powerful eagle. He was very strong and able to evade our attacks. After killing it with difficulties yesterday, the scientist said today that the eagle's eyes have experienced advance mutation, allowing it to see further than ordinary distance."
Uncle Darien sighed.
The scientist actually said that they wanted to get more of these more advanced mutation in their hands if possible. But hunting these rank 3 mutated animals were not that easy. If all of them experienced some kind of mutation one way or another, it meant trouble for them.
