Chapter 13 — The Hand That Carves Sin

The hand remained as pale as marble, devoid of any sign of life. The atmosphere in the operating theater plummeted to a freezing point.

"Has it failed?" a young surgeon whispered, unable to contain his anxiety.

"Silence!" the professor barked, his voice sharp and authoritative.

My heart sank into the abyss. How could this be? I had personally inspected every anastomosis; the flow should have been seamless. Where did the problem lie? Was it a vascular spasm, or had a thrombus already formed? I forced myself to steady my breathing and calm my racing thoughts.

"Give me a syringe of papaverine," I commanded.

The nurse immediately handed over a vial of the diluted medication. I manipulated the robotic arm, guiding the micro-needle with surgical precision to inject the area surrounding the arterial wall. This was our final resort. If the blood refused to circulate after this attempt to break the spasm, there would truly be no way to save the limb. Every gaze in the room was fixed on my hands—or rather, on that cold, steel instrument. Time seemed to stretch into an agonizing eternity. Just as the collective hope of the room began to shatter, a miracle unfolded. The pale, lifeless fingertips of Tran Da suddenly bloomed with a faint, rosy hue. It was like a crimson plum blossom opening amidst a winter snowdrift. That flush of warmth spread rapidly—from the tips to the finger pads, and finally, across the entire palm. The sickly pallor was washed away by a living, warm pink.

"It's open! Blood flow is restored!" the anesthesiologist shouted in triumph.

A wave of suppressed cheers erupted in the operating theater. Everyone let out a collective sigh of relief. Even the professor’s eyes turned glassy. He clapped a heavy, firm hand onto my shoulder.

"Well done, To Hoan."

My body swayed, the adrenaline that had sustained me through more than ten hours of tension finally draining away. An exhaustion as heavy as a collapsing mountain flooded over me, threatening to pull me under. But I knew it was not yet over. The next phase was the nerve repair. If the vascular graft allowed the hand to survive, the nerve repair would determine whether it could truly live again. It held the key to the hand’s future sensation and function.

"Continue," I muttered, gripping the edge of the operating table to hold myself upright.

Compared to the blood vessels, nerve repair demanded far greater finesse and, perhaps more cruelly, a stronger spirit. Nerves are the pathways of pain. As I peered through the microscope at the bundles of nerves, thinner than spider silk, the memory of that night four months ago clawed its way into my mind. The heel of a leather shoe, grinding down, twisting with malice. The sickening sound of shattering bone. The heart-wrenching scream of An An. A cold, piercing hatred surged from the depths of my soul. My hand trembled. The electrodes within the sensory glove faithfully captured that spike of emotional distress. At the tip of the robotic arm, the sharp micro-scissors veered off their intended path. A hair's breadth more, and I would have severed a vascular graft I had just finished saving.

"To Hoan!" The professor’s voice was like a thunderclap in my ears.

I snapped back to reality, seeing the terror and concern etched into his features. I looked down at my left hand. It was trembling uncontrollably inside the sensory glove. It was hatred. The malice I had forced into the shadows was now, in my moment of weakness, clawing its way to the surface, desperate to use my own hands to destroy everything before me. To destroy the very hand I was fighting to save. I squeezed my eyes shut, gasping for air. Sweat poured down my forehead, stinging my eyes, sharp and burning. Stay calm, To Hoan. You are a doctor. You cannot be governed by vengeance. If you ruin this hand now, how are you any different from him? You do not seek to destroy him; you seek to judge him. A fully restored hand, saved by your own craft but forever branded by the shame of his actions—that is the only true judgment. I repeated this mantra to myself over and over. I do not know how long passed, but finally, the tremors in my hand subsided. I opened my eyes, the cold focus of a professional returning to my gaze.

"I am fine," I said to the professor.

I returned to the task. Dissection, alignment, suturing. My movements were slower than before, but infinitely more stable. I cast every chaotic thought into the darkness behind me. In my world, there was nothing left but these nerves waiting to be mended. One bundle, two bundles... the median, the ulnar, the radial... I was like the most devout artisan, using the finest needle and the most resilient thread on earth, patiently repairing a masterpiece that had been shattered beyond recognition. Several more hours bled away. When the final nerve bundle was secured, I set down my instruments.

"Close the skin. Bandage it," I whispered, using the last of my strength. Then, the world turned black, and my body went limp as I collapsed.

I woke in a hospital room—not my own, but a temporary recovery suite arranged by the clinic. Sunlight streamed through the window, gentle and warm. The sensory glove had been removed from my left hand, replaced by a recovery splint. It lay there motionless, like a weary comrade-in-arms. The professor sat by the bedside, peeling an apple. Seeing me stir, he offered a weary smile.

"Awake, are you? How do you feel?"

"Professor..." I rasped, my throat raw. "The surgery... how did it go?"
