Nine Swords Burning the Sky: Starting from the Cold Iron Guards

At the head of the cold iron city, blood flowed everywhere. The young man Ao Xuan held the stick as dark as scrap metal and faced the blood clouds in the sky and the city. There are two rare high-grade swords of "gold" and "earth" dormant in his body, but they are like a peerless treasure mountain that cannot be smelted - the tyrannical origins of the two elements collide with each other. Instead of giving him powerful power, they block all paths of cultivation and become the laughing stock of "double waste". On the verge of death, his consciousness sank into the gray mist of chaos, and he could only receive a vague pointer from a mysterious being: "The city is too small! The wings are broken! Find the furnace... Cast the spine!" Hantie City is too small and cannot trap his wings. Abandon the city? But Chenggen has already seeped into his blood. The fire in the Nanli Sword Alliance was strong enough, but it was not suitable for his "wonderful iron". The great pride encountered the cold reality - no matter the inner or outer door, no matter water, fire, wind and thunder, all kinds of methods in his body were like nothing, and they were all dead ends!
