**Chapter 9: Slaying the Undead**

Zhang Xiaowen's apartment building, once a bustling urban hub, had become a death trap after the outbreak. The streets below, once lively with shoppers and diners, now teemed with shambling corpses. Four days into the apocalypse, convenience had turned into confinement.

"Cube… how do we get out…?"

"Current conditions are unfavorable. The horde density is too high. Without weapon systems, a direct escape risks severe injury. Recommend continued observation."

"The military will rescue us! They have to!"

"Lower your expectations. Social infrastructure has collapsed. Functional weapon systems are scarce. Additionally… humanity's darker instincts are surfacing."

Cube continued scanning the environment, disinterested in human optimism. Sensors suddenly pinged. **"Anomaly detected—1 o'clock, eighth floor."**

Xiaowen peered across the street. A young woman, naked and disheveled, sobbed against a window while a middle-aged man assaulted her, two others waiting their turn. Xiaowe's hope for solidarity shattered.

"Cube…"

"Offensive capabilities remain offline. However, I will initiate a hardware upgrade using local materials. Ion cannons are impractical, but Earth-level ballistics are feasible."

"You'll protect me, right?"

"Until upgrades complete, prioritize stealth. You must also learn to combat zombies to improve survival odds."

"But I'm scared!"

"Fear diminishes with repetition."

"How do I even…?"

"Begin with immobilized targets. Build nerve. Progress to mobile threats."

Without further discussion, Cube leapt off the windowsill. It yanked a cable from the wall and hopped down the stairs, floor by floor, until locating a female zombie on the fourth level.

"Greetings, Earthling. I require your biomass for training purposes." The zombie groaned, unresponsive. "No objections? Proceeding."

Cube bound the creature's arms with the cable and dragged it upstairs, securing it to a radiator in the neighboring apartment. Returning to the stairwell, it retrieved a knife from a slain zombie's skull.

**"Moron! Time to practice!"**

"No! Get that thing away!" Xiaowen shrieked.

**"Two options: Survive by adapting, or end up like that girl across the street. Choose."**

The bound zombie thrashed wildly at Xiaowen's voice. Cube monitored her trembling form pacing inside her room. Finally, the door creaked open.

Xiaowen inched down the hallway, gagging at the stench of decay. She burst into the neighboring unit, face-to-face with the snarling zombie.

"Don't scream. Noise attracts more," Cube warned. The creature's milky eyes locked onto Xiaowen, jaws snapping, dried blood caking its nightgown. "I… can't do this…"

"It's not human. Strike the skull or sever the spine. Leg dismemberment is optional."

Xiaowen gripped the knife, eyes squeezed shut, and swung blindly.

**"Open your eyes! Adjust left arm force by 20%, forward 20 cm!"**

On the second attempt, the blade pierced the rotting cranium. The zombie slumped, finally still. Xiaowen collapsed, sobbing into her knees.

**"Adequate for a first attempt. Return to your unit. I'll secure weapons and upgrade materials."** Cube leapt out the window before she could protest.

Mid-air, Cube grabbed a telephone line, swung onto a fruit stall's awning, then face-planted onto the asphalt. Nearby zombies turned toward the noise.

**"Stupid meatbags! Never seen a starship faceplant?!"** It transformed into a blue toy off-roader and zipped through the horde. **"Watch your feet, imbeciles!"**

Across the street, a survivor gaped from a window:

"Boss! Look—someone's playing with a remote-control car!"
