Chapter 452: Pacifying

Only Shi Yan was left in the vault.

That big vault stored thousands of types of cultivating and refining materials. They were so colorful and brilliant that they could easily dazzle people. There was a piece of yellow paper stuck on each kind of material to tell the name and its primary functions.

When the blacksmiths and the alchemists came here, they just needed to read the notes to know what kind of pellets or secret treasures those materials could fabricate. As for the heat control and the precise amount, they depended on the method the blacksmiths and alchemists would use.

According to Yang Zhuo, when one wanted to become a blacksmith, he had to have the human flame, and it would be best if he could use the earth flame. If one had the heaven flame, even a lousy blacksmith could forge extraordinary weapons.
