As Minos positioned himself over the alien robot corpse, everyone involved in the experiment took their positions, raising their guard in case anything strange happened.
At the same time, no one unrelated to the experiment stayed near them, aware that what Minos was about to do could somehow trigger a Lightning Tribulation.
The vast majority of the robot corpses left over from Minos' final battle against the aliens in the North Sea had not been opened to extract their essences. Since Emperor Stuart's group had experience with this before, they didn't dare to obtain such essences casually.
Other powers in the Spiritual World had experimented with it; while some had succeeded, many had failed. However, the Black Plain Empire did not try because Minos wanted to test something first.
He had only reached the necessary level after his breakthrough to level 90 about eight years ago. But only now did he have the time and inclination to do it.
