Legend of the Dragon Soul

Born human yet possessing a dragon soul, Lin Fan is deemed a waste with no ability to retain spiritual power in his body. With only four months before he is expelled from his clan for failing the assessment, he takes a risky path of cultivation, breaking through realms against all odds. He discovers a shocking secret within his spiritual platform—his spiritual embryo is actually a young dragon. The young dragon gets hungry and grows, and each transformation grants him a new ability. What if he has no spiritual power? A waste body hides a true dragon; one thought can shake the heavens! — Description from novelcodex.org
