My Mysterious Dad Gave Me an Island, and I Turned It into a Metropolis

A mysterious father whom I have never met suddenly gives me an island as a gift. I originally wanted my son to live a life of an island owner with no worries about food and clothing. I never expected that with the arrival of Qin Chuan, earth-shaking changes would occur on the island. "What? Are you going to represent the country in the Olympics?" "What!! Are they selling arms on the island?" "Then an autonomous island on the high seas turned into an international metropolis???" "Why? That island city also wants to implement a Mars immigration plan???" "Check!! Check for me!! We must find out what is going on!!" Various countries and forces sent spies to the island to check. What is jaw-dropping is... I don't know what means the island used to instigate a large number of spies... This novel and its characters are purely fictitious.
