Expedition

Riku Hirota went to the Arzotoc library and gathered some information for the pipeline he was planning to build. With the help of Naina, he succeeded to locate the place where he needed to have an expedition.

Expedition: it was the journey by a group of people with a particular purpose, especially scientific research, etc.

Moreover, the word expedition where Riku came from signified to fight a new type of monsters and to get some loots after killing them.

He was sitting in front of the transparent window, watching the glistening night sky. Those lights beamed his eyes, at the same time, let him feel comfortable and washed away all the problems he had.

"Hmm... What is my best thing to do in this world? Even I went to the library I can't guarantee that I can find a book that could bring me back to my world." He paused for a second, doesn't like to end this soothing experience.
