Chapter 419 (1/2)

Zhao Fengnian finished all this, with a long wooden clip wrapped in the fur of a spirit animal, he picked up a piece of cut refined iron and poked it into the hole in the ring.

”Zila!...” As soon as the refined iron bar entered the space, the sound of a bright thunderstorm sounded in the air.

A flash of electric light, the refined iron instantly red, into molten iron, dripping in the bottom of the prepared mold.

”Well, although it costs a lot of spirit stones, it can quickly and easily refine refined iron.” Zhao Fengnian takes back the blackened wooden clip at the front end and looks at Wu CAI.

Wu Cai nodded, looking at Zhao Fengnian as if he were looking at a monster.

How does this kid's brain grow in the end? How can he really beat him up, and how can he make lightning not hurt himself?

”These ten spirit stones can emit about ten times of this level of lightning, and one higher level of lightning, that is, the energy that can turn a small piece of dark iron into molten iron. Of course, it's just a small piece.”

Finish saying, Zhao Fengnian also used to draw the size.

”Well, it's a bit wasteful to refine refined iron. One low-level spirit stone is enough to buy a hundred catties of refined iron. The cost of black iron refining by other means is also lower than that of Tianlei gold refining device. ” Wu Cai nodded and said the key problem.

Zhao Fengnian also agreed and nodded, ”yes, the cost is too high, but there is no way. This ring can be shrunk as small as this. If it is narrowed again, the energy will be unstable and the lightning will be dissipated. However, it is very valuable to refine high-grade materials like meteorite iron. ”

After that, Zhao Fengnian took down the spirit stone and added ten high-level spirit stones.

The cost of these ten high-level spirit stones is not low, equivalent to 100000 gold coins.

Zhao Fengnian exchanged it through Tianxiang chamber of Commerce, otherwise he didn't have so many high-level spirit stones.
