One Piece: Supreme Check-In System - Chapter 40: Walking Around in Fish-Man Island

For the crimes he commited, Theo was executed by the exile to the outlands, beyond the limits of human civilization, where the S-rank monsters reigned supreme.Yet, rather than feeling despair, guilt or anything else... Theo was excited.He had no memory of comitting any of the crimes he was sentenced for. Or, to be more precise, he had no memory of doing anything in this world other than sitting in the prison-coach as it drove to the edge of the civilization.And how could he not, with the system prompt hanging out in the corner of his vision, promising to activate only once he set foot in the outlands?Turn the world into blocks... and mine them out. Craft whatever your heart desire. Construct, automate, explore and exploit!But when you hear the boss music kick in...Do you run, or do you stand your ground and fight?!And what if, while you play minecraft... Others play game of thrones?

He crossed over to a new world where humans have magical power. They are called warriors. They use their power to kill the monsters that appear out of nowhere. Dragons, Dungeons, and Magic users are pretty common in this world. If you want to live in peace, you need to have that power. You can also become a powerful clearing dungeon.

In this dangerous world, he has a system that can help him grow stronger. But he didn't want to be a high-profile warrior who attracts much powerhouse attention or become a lab rat. He wants to be Low-profile and grow strong using his system.

After an unexpected accident, An Luo was reborn as the young master of a business family. Even as his grandfather’s favored grandson, he seems to only be a cannon fodder in the brothers’ struggle to seize power. However, the most frightening thing is… the strange emotions that flicker in his little brother’s eyes as he looks at him. At that moment, overwhelmed by his brother, An Luo angrily thought: Could it be that he is doomed to never escape this vicious cycle of “brotherly love”?

An Luo(frowning): After rebirth, I don’t want to be together with some strange person.

Someone(suddenly appearing in the back, smiling): What did older brother just say?

An Luo: …Nothing.
