One of the Skills Yuuta got after the System Creator automatically redeemed all his rewards from the System was a Skill called Teleport, which allowed him to teleport in any place that he has been to before. This is a pretty overpowered skill but it has three days of cooldown so even though it can be used in tricky situations, it'd be best if someone could save it for the opportune moment before trying to escape.
But right now, with the World of Lucid and Earth in chaos, Yuuta could tell that every moment is an emergency and that he needed to act as quickly as possible in order to put a stop to it. As far as he knows, the System Creator had no chance of fending off Myrkidhr since he's the second most powerful Minth in the entire Minthian Race. Right now, the System Creator might very well be dead but Yuuta was hoping that such was not the case... or at least not yet.
