Eroos
introduce some conflict, like him catching the eye of a mob boss daughter or rich CEO daughter, etc maybe kidnapping, threats, blackmail, obstacles in general for the MC to overcome :D
its a fictional novel... MC has truth abilities, went into a different world, became a super-genius suddenly, adding some of my suggested elements shouldn't be too much of a stretch. Just like the car chases in fast and furious, its all for entertainment my guy.
Legendary_Gear5:Lol what... its supposed go be real world but in reverse ...when does the things you describe happen so often in the first world lol đ
