Crossing the Dragon of the Nest Builders

He traveled through time and became Brad, the protagonist of "Dragon Building the Nest". In order to live a leisurely life of ravaging male heroes, having sex with female heroes, and catching a princess to scare the king, Brad decided to expand the dragon's nest and recruit powerful subordinates to compete with the braves. However, in fact, the specifications and subordinates of Dragon Lair have already reached full level, while the enemy is still working hard to graduate from Novice Village. In short, this is a piece of imagination after playing Dragon in the Nest and watching OVERLORD. There will probably be some ACG visuals like Europa Universalis, Total War, Lance, Demon King's Expedition Fortress, etc.? Also: Regarding the first-person issue, except for Chapter 1.2 And the intermission, it is all third-person. Please feel free to eat it.
