Research For the Sacred Ground’s Rise

"As the Iron Essence was too expensive, Junior Brother Yundi could not buy it."

Shen Tian was very straightforward, not leaving any face for Qin Yundi. It counted as taking revenge on Qin Yundi for selling him out to the Sacred Leader.

The Sacred Leader nodded and seemed to be deep in thought.

…

It's true. The Iron Essence is one of the main materials for cultivators to create supreme-grade Dharma artifacts.

Iron Essence as small as one's thumb can be sold for a high price of 3,000 Spirit Stones. It can be said to be extremely expensive.

Looking at the size of the Yin-Yang Demon-Penetrating Gun in Qin Yundi's hands, if it were really to be completely made with Iron Essence, then, most likely, without a few hundred thousand or even a million Spirit Stones, it would be impossible to do so.
