I'm not so sure this is simply just a simulation with Leonel as the mastermind / in complete control, and he is simply looking for an answer. Remember, Leonel was able to interact with those who are most likely outside of said simulation during the spear tribulation. Not only could he interact, but he even stole many spear paths from one of those individuals. If someone is running simulations in search of a specific thing, they must be isolated. One of the worst things you can do in such a project is let one simulation gain data from / influence another - it would be equivalent to contamination. If the people were from the real world, interference from unknown parties is just as big of a problem. Of course, this is all based on the fact that he truly interacted with people from outside his simulation... and not just a part of the simulation themselves pretending to be from outside.
So Leonel is living on his own simulation. And is not the first one. Now the mistery Is to know what makes this Simulation special and why he considered it a faliure. So many questions... I guess this should have been expected considering how his ability index and dream force where progressing since simulations and probability where always a core of how he decided to develope his ability from the begining.
