Dimensional Travel

As soon as he traveled through time, he was thrown into a desolate place by the system (Ultra System). He said it was special training. Bai Cha looked at the group of monsters in front of him and said, special training is to fight monsters? ! After finally completing the special training mission, you were bound to another system (dimensional system)? ! Even if you bind two systems together, the two systems are still a pair. It's really super (ultra) excessive! Even if it was too much, I was put in jail (learning knowledge) for three years! But after traveling through one Ultra universe after another, I suddenly discovered that Tiga and Triga are mine... I actually owe Noah, Zaki, and Regedo...? ! What's even more outrageous is that I am actually Saka himself? ! According to the setting of this novel, Saka is the most powerful in combat.
