Dragon Master, but Battlegreymon

In a world where humans and dragons coexist, humans can contract their own dragons when they reach adulthood and become powerful dragon masters. Long Yi traveled through time and contracted with Fighting Greymon! Looking at the dragons all over the world, Long Yi smiled shyly: "Dragon? Dragon points are good! All dragons!" When Long Yi brought his fighting tyrannosaurus with one claw and one dragon, everyone went numb! "What? You ask who is the most incredible dragon master in this era?" "Of course it's Long Yi! Could it be me?"
