Super Bodyguard in the City

Luo Jun is a glorious little security guard, also the most awesome security guard, bar none! In the bustling city, Luo Jun, with his superb skills and extraordinary wisdom, is like a fish in water. When the enemy is fierce, he breaks them with his fists. When the enemy is cunning, he breaks them with his wisdom. But alas, when the beautiful maturity of the divorced female homeowner, the unparalleled intelligence of the ice-cold president's sister, and the heroic demeanor of the policewoman sister, weave a net of love and come at him, Luo Jun's fists and wisdom become useless? The ten thousand zhang of red dust, I cannot break!
