Heng Wuji has lived for a thousand years.
In the past thousand years, he had seen enough of the humans in the wasteland killing each other for a few pieces of fungal bread, and he was tired of seeing those aberrants who claimed to be evolvers showing off their disgusting fleshy wings.
As the only perfect symbiote of the "Scarlet Mother", he is immortal, but cannot feel the coolness of the wind, the deliciousness of food, or even the pain of bleeding. He is a walking tombstone, trapped in the cage of immortality. During these thousand years, his only pastime was to watch humans repeat the cycle of war and destruction.
Until that day, a hunter from the Ice Coffin Council found him and presented him with a pure serum left before the war. After the injection, he actually smelled the rotten scent of wild flowers in the hunter's arms. At that moment, his thousand-year-old psychological defense completely collapsed.
It turns out that the so-called "gene ascension" is a complete scam, and the nanomachines have never failed. He himself is the highest stage of evolution, but his senses have been locked by the will of the upper level, and he has become a specimen of despair.
When he learned that restarting the "Scarlet Cube" required the sacrifice of the only "living key," Heng Wuji stood on the ruins for a long time.
He hadn't felt pain in a thousand years.
This time, he wanted to feel pain for his own demise.
