Lord of All: Start with a Moving Castle with Cannons!

Traveling to a world where demonic energy is revived, everyone will awaken a random initial territory when they turn 18. By killing demons, you can increase the level of your territory and obtain construction points. Lu Yang awakened a super castle that could move freely and had its own elemental cannon! … Demon soldier: "Holy shit, it's a moving castle, and it even has an elemental cannon. Isn't this bullying? Run!" The little demon lord: "Sun! The demons obey the order, you guys will hold on for a while, I will go and invite the demon king~" Demon King: "Don't look for me, don't look for me, I can't hear you..." … When everyone is still worrying about expanding their territory and dealing with the demon attack, Lu Yang has controlled the mobile castle to freely shuttle across the vast continent, killing demons and upgrading like crazy! He even complained in a boring way: "You are so weak! If you upgrade again, you will almost reach the top. What kind of cannon should you build next for fun?"
