Dust Wind

There’s SIS in great Britain, CIA in the US. In Huaxia, there’s Dragon Division, known as the mysterious power of the East.
When a soldier that originally failed to be selected to join, appeared on the Dragon Division’s list again, no one noticed, that this inconspicuous and humble-looking guy was actually the Dragon King of the division, the one that’s most difficult to deal with.
Mercenary: “Report, our squad is under attack, suffering heavy casualties!”
Commander: “How many enemies are out there?”
Mercenary: “Just… just one! There’s a joker card in his hand.”
HQ: “What?! Hurry, retreat!”

Ace of The Dragon Division

<p>Disclaimer: This is fiction, try not to feel offended because the MC is now going to go to other countries and start some sh*t and it may feel like they are talking down on the foreign countries. Don't forget, the MC first started sh*t in Huaxia and took care of a lot of domestic garbage too. In addition, the common enemy in this novel isn't the foreign countries, but a group of elites (Capital Society) behind the curtains that hold the majority of the world's wealth and basically plays the whole world like its puppet.)</p>
