Below Zero, She Set Herself Ablaze and Blasted Open the Way To

The Age of Extreme Cold arrived, and temperatures worldwide plummeted to minus one hundred degrees. Civilization collapsed beneath the ice. Han Zheng, the last expert in low-temperature bioengineering, used herself as a test subject, implanting her nerves into an ice-crystal core and becoming a living thermal core. Lu Zhaoye, a former military icefield hunter, wandered alone, burdened by the remnants of the gene bomb she had detonated herself. As humanity's last refuge stood on the verge of being swallowed by frozen earth, Han Zheng set herself alight, using her flesh and blood as a fuse to blast open a rift leading to the geothermal springs at the planet's core. Before she froze completely, Lu Zhaoye had to carry that beating thermal core and break through the endless night.
