Tensei Kenja no Isekai Raifu ~Daini no Shokugyo wo Ete, Sekai Saikyou ni Narimashita~ - Chapter 144 - I Tried Searching for a Cockatrice

Humanity had finally ended the war with the Demon Race and sealed them away, forever.However, they now have to face the treat of the Shadow World, an equally dangerous threat to their civilisation under the rule of the Emperor!Facing only misfortune from a young age, Nikolaus Reinhardt never expected anything good to happen to him.But his world completely changed when he awakened as an Ascendant, and accidentally summoned a member of the Demon Race in his house.Just because he messed around with a god damn book!

When the land was occupied by demons, people had no choice but to flee to the sky. After transmigration, Ricky found that he had become the City Lord of a Sky City. He quickly became familiar with this new world and established a clear direction for survival, which was to resolutely engage in farming (kingdombuilding)! He would farm (kingdombuilding) diligently, develop vigorously, and then gallop through the skies. If anyone disagrees, then launch a great sky battle. Or a war!

It’s a long road to bury the dream deep in my heart and carry the wishes and dreams of my dear friend and teacher.

In the pirate world where the strong are respected, fight a bloody long road.

“Pirates… maybe they’re all damned people.”
