"Yes, you just need a little bit of this type of metal in order to corrode any part or organ of any creature’s body. It will produce a special type of secreted substance that, once filled inside the creature’s body, will give it a terrifying nature that allows it to counter the Totem Light. It would be similar to making water into a type of ice that could be compared to steel. With the emergence of this strange and powerful transformation ability, you could only imagine the excitement on the faces of the expert researchers. This is truly a discovery that will transcend time and eras!" said the silver-faced man, shaking his head. "As for how the crystal derivator came into being, we used the resonance technique that we had perfected much earlier, and coordinated it with this type of creature-corroding black copper, to forge the current crystal derivator known by everyone. However, during the last stage of the experiment, an accident occurred."
