Lex dismissed the last of his clones and sat with his back to his chair, letting out a deep sigh. One unexpected, but somehow predictable, result of using consciousness clones was severe mental exhaustion. Even if it was as if he had another brain functioning independently, the energy for all that processing still derived from his original body and soul.
Not to mention that he had been using multiple clones, sometimes even at the same time, to check whether that was possible or not. As a result, he had been completely exhausted.
It was not a big deal, for he had more than a whole day before the assembly began. What he had to decide now was whether or not he would attend, for if he missed this one, he would have to wait 100 years for the next one.
