Dragon Game: All My Dragons Are Ranked 'SSS' Novel

[You have just awakened your first dragon: SSS-Rank Fire Dragon.] Drahon was born with dragon-like horns, and because of that, his parents abandoned him at an orphanage. Mocked, bullied, and branded a freak, he never knew where he truly belonged. Until one day, while serving punishment, he stumbled upon a mysterious egg... A dragon egg that opened a portal and led him into The Dragon Game. [You have summoned an SSS-Rank Demon wrymling.] [You have evolved your SSS-Rank Primordial Frost Dragon into a Multi Fire-Frost Dragon.] [Upgrading Fire-Frost Dragon Roar ×10...] Bond with dragons and summon them in battle? Of course. All Ranked 'SSS' Draconic skills? Master them. Monster bosses? Shatter them. Half-dragon, half-monster abominations? Burn them. Mandatory roleplaying? Absolutely. Rule kingdoms, command medieval armies, and go to war. Enemies? They’re just EXP. And just after Level One, he uncovers the shocking truth behind the game’s existence... And discovers the reason for his horns: he’s half dragon, and that grants him the ability to transform into a half dragon, half human form. [You have just slain a cerberus-class half-dragon monster.] [Absorbing essence...] And now? He’ll be more than the horned freak they abandoned — He’ll become Dragon Lord. [A/N: It gets much better after level one]
