Progress
The next day.
Alex fought Letizia with only a sword, trying to see her progress in the sword. After that, he gave her a few pieces of advice and told her he would come every few days to check on her progress.
He then left her alone and began his training.
This might be the longest training he had ever faced because it took him a whole half-year to first create the three arrays. And it took him another half year to master it to make it combat-ready. Of course, Letizia became Alex's guinea pig for these arrays.
Luckily, Alex used his Simulation Room to create a battlespace that could replicate such a battle. With this, Letizia also got a precious experience.
She always tried to land a hit on his body while Alex used everything in his repertoire. Nonetheless, the fight lasted pretty long due to Alex could only use his array to attack. In the end, Letizia died many times in that Simulation Room.
