Chapter 419

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.

Even if Wu Cai saw Zhao Fengnian put ten high-level spirit stones on it, he could not help but stay in a daze. This is 100000 gold coins, enough to buy how many spirit grass and spirit materials!

"The cost is high, so I haven't tried it before. I'll try it until you break through."

Zhao Fengnian looked at the ten high-level spirit stones on the disc, and his expression was also a little trance. It was his first experience to throw ten thousand gold.

After the completion of Zhao Lingshi's new year, he began to prepare for the new year.

"Wait a minute. I heard that when refining Reiki materials and utensils, they must be controlled by psychic force. No other mold can withstand such high temperature. Moreover, the aura in the material will disappear after melting. "

however, Wu Cai stopped it in time and gave the reason.

It was the first time that Zhao Fengnian heard of this kind of thing. He had also tested refined iron, and the Reiki material had not been tested, so he did not know the taboos.

"First ask someone to carry a water tank and put it below. In addition, you can show me the drawings you need to make."

Then Ruixue went out to prepare, and Li Tiezhu took out a set of drawings.

Wu Cai took over the drawing and looked at it carefully. Then he frowned and looked at Zhao Fengnian.

"Are you? Do you want to be a catapult? "

Seeing Wu Cai's inquiring eyes, Zhao Fengnian nodded, "yes! Mr. Wu, I want to make a set of aerolite catapults. In this way, even if it's a powerful defensive armor like the alligator, it can be easily penetrated! "
