Testing it with the Cursed Plutonium Dragons was not a whim of the moment.
In theory, Slimes that had inherited some of the reproductive cell traits of dragons should have no trouble reproducing inside a real dragon.
But because the gap in rank was too great, Anvis was not certain whether they could obtain the Cursed Plutonium Dragons' life information.
Entering the high-risk testing area of the Laboratory, Anvis activated the Laboratory's composite defensive array after the heavy alloy gate lowered, then released the three Cursed Plutonium Dragons.

The moment the dragons appeared, a red light on one side of the Laboratory lit up, indicating a
