Ma Jiayi, the former master of the "Shadow Pavilion", once single-handedly stirred up the underground world, but chose to hide after the organization was disbanded. Accidentally bound to the "Hidden Dragon Hiding System", the system rules are clear: only by keeping a low profile and hiding your strength can you obtain points and redeem top abilities; once your true strength is revealed, not only will your points be cleared, but a punishment mechanism will also be triggered. In order to comply with the rules of the system, he took off his suit and put on a delivery uniform, becoming an ordinary delivery boy traveling in the neon city.
In front of the Genting Club, he held a half-filled box of lobster spaghetti. Faced with Lin Haoyu, a second-generation rich man, who was crushing him with his leather shoes and demanding a 100,000-yuan suit, his clenched fists finally loosened. The prompt on the system panel, "Be patient in responding to provocations and get 1,000 points," made him suppress the urge to knock the opponent to the ground in an instant. No one knew that this deliveryman, whose uniform was stained with oil and whose helmet was scratched, had the temperature of a man who once controlled tens of billions of underground assets hidden in his palms; no one expected that this deliberate forbearance was just the first low moan before Qianlong raised his head. When the system points are gradually redeemed for the thunderous means under disguise, and when former enemies and old troops appear one after another, Ma Jiayi will eventually embark on a counterattack path belonging to the hidden dragon under the shackles of "low-key".
