Perhaps due to the root of the evolution being from an Ancient Species, Delta's evolution took longer than usual, causing Bai Qi to grow expectant.
If Delta could directly evolve into an Ancient Species, that would be great, as compared to the body of an Ancestral Beast, an Ancient Species had an absolute advantage.
Under Bai Qi's expectant gaze, Delta's body finally began to change. Its form visibly enlarged at a noticeable speed, gradually exceeding the containment range of the lab.
Luckily this was the Moon Night Tower. As soon as it sensed the changes in the lab, the tower's protective mechanism was immediately activated, expanding the initially average office-sized lab into a broad square.
The Moon Night Tower was regularly called upon to treat injured pet beasts, among which there were some Giant Species, so this sort of enlargement was regarded as a basic feature.
