Lin Yu, an ordinary office worker, unexpectedly transmigrates and falls onto the Mongolian grasslands in the world of The Legend of the Condor Heroes. At death’s door, he is saved by Li Ping, Guo Jing’s mother, and unexpectedly binds himself to the Heaven and Earth Reclamation System. In this world, he forms a brotherly bond with the infant Guo Jing and enters Qiu Chuji’s tutelage alongside him. Starting with horse stances and the practice of Everlasting Spring Technique, he uses the System to strengthen his internal energy foundation. With his foreknowledge of the martial world’s secrets, he also avoids the wrong path of practicing the Nine Yin Manual and forges a solid, upright path in martial arts.
On frigid nights in the grasslands, he follows the System’s guidance to avoid danger and find supplies, protecting Li Ping and his young brother Guo Jing as they safely endure the winter. Amid the misty rains of Jiangnan, he learns the Eighteen Dragon-Subduing Palms from Hong Qigong, blending in the soft, yin force of the Nine Yin Manual to refine the technique. The resulting cold energy cloaks its fierce power, catching martial heroes off guard. The Southern Song is then tottering, treacherous ministers hold power, Jin armies press at the borders, and refugees are scattered everywhere. Seeing the suffering of this land, Lin Yu can no longer stand by as a mere observer. The System gives him more than the means to survive: it gives him the chance to change the world.
He rallies righteous fighters from the martial world, including Lu Chengfeng and Yinggu, uniting forces against the Jin. He breaks through deadlocks with martial prowess and wins people’s hearts with compassion. From a young boy on the Mongolian grasslands, to the renowned “Cold Dragon Palm” master of the Jiangnan martial world, to the leader of a rebel army that rises up and drives out the Jin invaders, Lin Yu advances carefully at every step. In the end, he overthrows the decaying dynasty and founds a nation called Xia. He drives the cavalry west, expanding its territory to the borders of Europe, then leads a fleet east and turns the Pacific into an inland sea. This journey of transmigration, which began in a felt tent on the grasslands, ultimately uses the System as its guide, martial arts as its spearhead, and the people’s support as its foundation to open up an unprecedented and boundless world.
