The Eternal Supreme - Chapter 114

However, objects that had gone through thunder tribulations were extremely powerful, and hence the fifth-tier was a watershed for alchemists. Many alchemists could refine fifth-tier objects, but most of them would turn into ashes in the face of the thunder tribulations, stopping the alchemists from becoming fifth-tier alchemists.

Yuan Hao was one of such alchemists.

The Primordial Thunder Talisman in Sun Zhengzong’s hand was a fifth-tier jade talisman. It contained a trace of thunder force that some mighty alchemist had forcibly taken when an object was transcending the thunder tribulation. Such a jade talisman was extremely valuable. It could be used directly when refining lower-tiered objects, trigging the force of thunder to improve the object’s grade. Moreover, since the thunder force in it had already been refined, it would not produce a strong damage, and was safe to use. Therefore, it was viewed as a precious treasure by all lower-tiered alchemists.

Sun Zhengzong turned and saw that Yunxiao’s refinement had entered the stage of six spins. A trace of resolution immediately replaced the reluctance in his eyes. Abruptly, he activated the jade talisman in his hand and slapped it on the cauldron.
