Dragon Contract: Dominion Over Heaven

While others tame dragons through bloodlines, Lin Ye makes all races submit! Considered a waste, he unexpectedly contracts an ancient shadow dragon and awakens a rebellious dragon contract. He commands spirit dragons, battles fierce beasts, uncovers conspiracies, and overthrows the old order. Those who disrespect dragons are slain; those who defy the heavens are suppressed. Watch as the youth rises with his dragon, ascends to the dragon domain, and achieves the supreme legend of dominating the heavens. — Description from novelcodex.org
