Is the Dragon Master Weak? I Build a Dragon Army!

Invasion of alien beasts, war among all races, Qin Yang traveled to a world where everyone changed jobs. Human beings can undergo professional awakening at the age of eighteen. Someone awakens a combat profession and can upgrade through dungeons to increase their strength. If someone awakens a life profession, they can provide backup supplies. But Qin Yang has awakened the hidden profession of SSS - Dragon Controller! It's a pity that the dragon clan has long existed in ancient legends. Without dragons, Qin Yang is destined to be an ordinary person! Fortunately, at this time, the system woke up: [Ding, congratulations to the host for awakening the dragon master profession and getting a newbie gift package - Frost Dragon! As long as he keeps drawing draws, Qin Yang can get all kinds of dragons! [Ding, congratulations to the host, you won the ghost dragon! [Ding, congratulations to the host, you drew the dark dragon! [Ding, congratulations to the host, you have drawn the Holy Dragon of Light! [Ding, congratulations to the host...] So... While others are still working hard to defeat monsters and upgrade, Qin Yang has already created his own Dragon Clan Corps!
