At the palace doors, Lex took in a deep breath as he reviewed all the information he had gathered, as well as his plan. The most ideal situation would be if the guard and staff in this castle were mostly around his level, with a few notable exceptions who would be counted as bosses. If this were a video game, that is how things would proceed.
Unfortunately, real life did not operate like a video game. As lex had personally experienced, time and time again, there were countless strong cultivators everywhere, all living their own lives. Just because you were low leveled did not mean you would not run into them. In fact, if you went to specific areas, your chances of encountering strong cultivators would increase exponentially.
