It is an age where monsters walk the earth and animals mutated by an extraterrestrial microorganism from Mars. Humanity is decimated and retreats to its last few cities, clinging on to survival.

Yang Tian is a young man with dreams of becoming the greatest Warrior.

After suffering a setback in his dreams, he found a dragon egg that belonged to his grandfather. Amazingly, the egg hatches, and Yang Tian is suddenly granted the power of a pet dragon! However, the world is cruel and dangerous, and Yang Tian must overcome not only the threat of monsters, but also of other Warriors who want to see him fail. Can Yang Tian and his pet dragon overcome the numerous challenges in this brave new world?
