Li Zheng, the former Crown Prince, is framed by a Noble Consort and exiled to a frozen wasteland where temperatures plunge to minus forty degrees. With no clothes or food, the entire court waits for him to freeze to death. Faced with certain doom, he neither leaves his fate to heaven nor begs for mercy. Instead, he harnesses ancient geothermal techniques, cultivates cold-resistant wheat, forges mysterious weapons, and gathers scattered soldiers and displaced survivors of the frozen wilderness. Together, they build a colossal fortress city equipped with ingenious mechanisms. As barbarian cavalry and a decaying dynasty launch successive attacks, he sweeps across the land with his formidable Wolf Cavalry armed with long sabers, raising a blood-red banner over the frozen plains. Once a disgraced heir whom anyone could bully, he no longer relies on imperial protection. With his own hands, he builds an invincible divine army in this desolate frontier, crushing treacherous court officials and formidable enemies beyond the border. On the eternal frozen wasteland, he carves out a path to survival for the people, one that refuses to submit to the old dynasty.
