The Tauren Have Retreated and I Will Protect This Heroine!

Others come with their own system cheats when they travel through time, but I am better off just dressing up as the "tool man" male protagonist of a crappy Galgame! I started with a broken crystal, but I became the only descendant of the dragon clan? Wait, that "tauren" brother... It seems like your target is my harem? The dragon's bloodline awakens, and the road against heaven begins! Tearing green tea with my hands and stepping on the tauren with my feet, in this life, I will be a strong man who controls my own destiny, become a true dragon knight, and protect the one I love in my heart!
