Kong Dao was born in the Sea of Beasts. Being able to grow up in an environment where dangers were unpredictable and where there weren't many people around meant that he had unique talents allowing him to survive. If not, he would never have been taken in as Duan Muque's disciple.
Needless to say, his experience living alone on Mars also showed how extraordinary he was.
Even though the Federation seedlings had spent several days together, his sense of belonging towards them wasn't strong. Furthermore, on the first and second day in the fight for the Body Strengthening Freedom Pill, he was defeated due to Wang Baole's Numinous Treasures. However, he had chosen to give up the fight then due to the regulations and certain inhibitions. If he were really to battle Wang Baole head-on, he was confident that he would win.
