Ling Yi, a young man, joined the army with the dream of being a general. From a scout in northern Xinjiang to a prince regent, he went through hundreds of battles in his life and became famous all over the world with the name "Fire Kirin". Amidst the iron cavalry of the Canglang Clan, the poisonous mist of the southwest barbarians, and the conspiracy of the powerful officials in the court, he always adhered to his original intention of "protecting the Yan Kingdom". The "Front Arrow Formation" he founded rewrote the rules of war in the cold weapon era. The military garrison system he promoted allowed the people on the border to live and work in peace and contentment. His "heroic sympathy" with the enemy chief Tuoba Ye went beyond racial hatred. When the smoke cleared, he used his sword and blood to usher in a hundred years of peace for the Yan Kingdom. However, at the peak moment, he chose to return to ordinary life and spend the rest of his life writing the true art of war - not how to defeat the enemy, but how to protect the fireworks in the world.
