Once the diplodocus died, Jake quickly removed the red crystal inserted in its forehead. According to Lu Yan and the others, another creature had always hurried to retrieve it before they could retrieve one. Therefore, he wanted to make sure that there wasn't a difference or an important detail that he may have missed from the one analyzed during his second trial.
Spending the Aether point required for the scan, Jake checked the crystal analysis report line by line, but he soon shook his head in disappointment. The information provided was identical. In other words, apart from serving as a vessel for the dinosaur's soul, he still didn't know much more.
Nevertheless, if the spirit of these creatures and the program governing their behavior was contained in these crystals, it was logical that the owner would seek to recover them in case of death. By inserting the crystal into another body, he could easily create new minions, although Jake was not sure if it was that simple.
