“Listen carefully, Jeong Jian.” Jeong Jinman is the former team leader of the massive mercenary company Babylon and the operator and administrator of Murthehelp. Murthehelp is a secret weapon shop Jinman built in the basement of his home, disguised as an agricultural equipment store. It classifies users by code and provides various necessary equipment. They are categorized into Red Code (Killers), Purple Code (Spies), and Yellow Code (Cleaners), and all code users have an obligation to protect the Green Code (Administrator). Jeong Jinman is also the uncle who has raised his orphaned niece, Jeong Jian. However, to protect her from various threats, he fakes his own death. Meanwhile, he plans to seize Babylon's main server with reliable colleagues to use as a bargaining chip and infiltrates Babylon disguised as Bale. During this time, Jian leaves her uncle's side and lives under a new identity in a new place. However, to capture Jeong Jian and Jeong Jinman, Babylon and a suddenly appearing new faction threaten them. Will Jeong Jinman and Jeong Jian be able to escape Babylon's ruthless attacks and protect everything?
The uncle who secretly operates Murthehelp and raised his orphaned niece, Jeong Jian. He was once a highly skilled team leader for the massive mercenary company 'Babylon' but left everything behind to return home. Although he doesn't show it outwardly, he cares for his niece Jian deeply. As expected of a former elite Babylon leader, his combat skills, situational judgment, and tactical planning are top-tier. He is quiet and appears blunt, but he is a classic tsundere who takes good care of those around him. (He is also tall and quite handsome.)
The niece who was taken in by her uncle Jeong Jinman, her only remaining relative after losing her grandmother and parents. From a young age, she was taught by Jinman how to handle crisis situations and subdue enemies. Under Jinman's tutelage, she also learned how to handle firearms and practiced Muay Thai. After learning the truth about Murthehelp and her uncle's secrets, she moves to a quiet fishing village under the new identity 'Lee Arin' provided by Jinman, leaving with the promise to return once everything is settled.
A member of Babylon. He is an extremely cruel individual who shows no emotion. He shares a deep, ill-fated history with Jeong Jinman due to a past incident. Bale harbors a strong hatred for Jinman and targets his family, including Jeong Jian. (Jinman also hates Bale.) As a top-tier mercenary with overwhelming combat experience, he is a dangerous figure that even other killers cannot easily face.
The female head of Babylon's East Asia branch. She is one of the members of the new faction that appeared to capture Jeong Jinman and Jeong Jian. She lured Bale to a specific location to test him and is a cold-blooded individual who ordered a team from Japan, including Q, to either recruit or eliminate targets based on their cooperation.
The mercenary team leader of Babylon's East Asia branch and J's older sister. Q is also one of the members of the new faction dispatched to capture Jeong Jinman and Jeong Jian.
The co-leader of the Babylon East Asia branch mercenary team and Q's younger brother. He was dispatched to capture Jeong Jinman and Jeong Jian and is also a member of the new faction.
Amidst the attacks from Babylon and the newly emerged faction seeking to capture Jeong Jinman and Jeong Jian, will the uncle and niece be able to survive?
