Blue Blood Debt

Immeasurable merit? No, it's driving me to kill! When I woke up, cold metal pressed against the back of my neck. The system that claims to have "immeasurable merit" gave me the first task in my mind: kill the pregnant woman in the hospital bed next door, or else randomly wipe out ten of my relatives and friends! "The fetus counts as one life. Killing one and saving ten will bring immeasurable merit." - Its voice was as cold as a knife. The scarlet countdown is bleeding in front of your eyes, and the price of failure is the life of your loved one. To hell with merit! Fuck optimal solutions! When the system successfully activated the "gift package for newbies", the pen in my sleeve pierced the hypocritical light screen! Zila——! Blue blood splattered, and the system alarm screamed: "Error! Core... You have no idea what was released..." The broken light screen and blood-stained pen merged into my body strangely. A colder and more terrifying voice sounded in the depths of my mind: [Human, what have you done? I thought I had ended the devil, but I personally released... The creditor? And the cleaning lady, whose wrist was shining with the same faint blue light, was pushing a cart in the hospital corridor at three o'clock in the morning, watching me quietly... Merit? I want to pay with blood! But why is this blood cold blue?
