I Asked You to Pilot a Mecha, Not Forge the Zerg Queen into a Weapon

In the year 2050 of the Star River Calendar, the interstellar insectoid race and the silicon-based mechanical race invaded, and humanity's mecha pilots saw their defensive lines collapse across the board. Su Ye, the human race's greatest mecha mechanic, was reborn on the day his home planet exploded, returning to the day in high school when he awakened his mecha talent. In his previous life, genetic damage left him fit only for a logistics job. In this life, he bonded with the [All Things Deconstruction and Synthesis System]. While others were still spending hundreds of millions of star coins on standard mechanical armor, Su Ye went straight to the black market and bought the corpse of an extraterrestrial void insectoid. He extracted its bones, smelted its neurons, and synthesized the only "biological symbiotic mecha" in the entire interstellar realm. Thus was born a ferocious battle armor with insectoid bone spurs, the ability to leap through the void, and the power to devour and evolve. Its design grew ever more Lovecraftian. Years later, when alien gods descended, Su Ye summoned a supreme battle armor a million zhang tall, stitched together from the remains of countless colossal beasts from across the stars, and cleaved the Star River in two with a single slash.
