Zhang Tie couldn't wait to open the Living Beings and Communities Management Panel of the Castle of Black Iron. He selected the Micro-organisms Management Projects under Carbon-Based Living Beings and Communities Management Item and further checked the latest mutation and evolution process of yeast fluid.
The familiar semi-translucent dialogue box appeared in front of him. Besides that bottle with yeast fluid inside, there were several photo samples of the control groups.
The photo samples of the first comparative group were about the yeast individuals under microscopes before and after evolution and mutation.
Before mutation, the microorganisms looked as common as water drops or beans of oval or irregular round shapes. They were semi-translucent and different-sized. However, after mutation, they looked greatly different in shape. In Zhang Tie's eyes, the microorganisms after the mutation were like miniature gourds which looked pale emerald and brought one a sense of vitality.
