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

Those who had taken refuge in the city heard about how the leader of the Deviant Corp shot down drones and their faces looked dignified.

Those special forces did end up coming here.

The remnants of Black Cat said to Deviant's team captains, "Their strength is not the main problem. The key is the latest soft bulletproof vest they are wearing that was developed by the M Nation's Ministry of Defense. Our bullets have difficulty penetrating, and they can easily shrug off the impact with the bullets' power. They are also wearing special military helmets and it's difficult to cause fatal injuries to their heads. We had to sacrifice our members to take out two of their soldiers using suicide bombing. You guys will have a hard time taking them out unless you have missiles, explosive packs, or a large caliber gun. Once they get close, you might be dead before you even shoot."

The others felt more scared having heard what they said.
