In autumn of the fourth year of Daguan, when the Khitan harassed our borders, I deployed the Mech soldier "Evil Vanquisher" to fight beyond Yanmen Pass. Unexpectedly, the warrior's components malfunctioned, unable to distinguish friend from foe. My junior Xie Zhuo bravely broke through to escape, and in his desperate struggle, finally destroyed the mechanism. However, my brother's hands were permanently damaged, ending his lifelong pursuit of cultivation.
Years of effort created not a divine mechanism but a grave mistake. Reflecting quietly, I deeply regret my actions.
I know I was obsessed with success, greedy for mechanical advantage, and arrogant in my approach, which led to disaster. My sins are heavy, but suicide would solve nothing. Therefore, I have requested expulsion from our sect and abandoned all the esoteric martial arts I learned, living with daily remorse.
I initially wanted to melt down this armor, but my junior, still compassionate, renamed it "Heartless." A puppet without a heart brings unexpected calamity. I've arranged a mechanism formation in Cliff Cave to seal the core components of "Heartless" and vow never to touch mechanical arts again, nor set foot in this cave. I hope others learn from my mistakes.
