After finishing everything he begins to focus on his food. At the same time he was thinking about what is the condition of his homeworld. He could also feel that his clone did not use that much Mana so that means the situation of Earth wasn't that critical and because of this his clone also did not take action.
Sometime later, he finally finishes food and after that he left the restaurant. Right now he was thinking what to do at this moment. As you know, he decided to rest for the day so he was thinking about what to do.
After thinking for some time, he decided to go to the library because he also wanted to know about the history of this Kingdom. The best place is the library where he will get to know about all the history about this place.
