Zhang Yuchen found the big dragon. The monsters with fire attributes all have their own natal beast fire. The dragon has been immersed in the ice and fire yin eyes since it was born. His own natal beast fire also absorbed the ultimate fire attributes of the ice and fire yin eyes. For him, the black iron ball can be easily refined.

"Dalong, you are my good helper." Seeing Dalong refining the black iron ball for Zhang Yuchen with his natal beast fire, Zhang Yuchen was so happy.

The black iron ball melted away bit by bit. At the beginning, the black iron on the surface melted away, and a faint golden color appeared. Zhang Yuchen looked closely and was immediately excited.

"Xuanjin! It turns out to be Xuanjin! No wonder this thing can be so heavy. It turns out that it is integrated with Xuanjin!" Zhang Yuchen was very excited. Xuanjin was a higher-grade refining material than Xuan iron. If the son of the Sun-Destroying God Wheel could integrate Xuanjin into Xuanjin, its sharpness and quality could be greatly improved.

"That's great. Black iron can increase the strength of the divine wheel, and Black gold can increase the sharpness of the triangular spikes. The two complement each other and can enhance the quality of the divine wheel!" Zhang Yuchen said happily.

Two hours later, under the refining of the dragon's natal beast fire, the Xuan Iron and Xuan Gold were melted. Zhang Yuchen hurriedly sacrificed the Sun Destroying God Wheel and brought the melted Xuan Iron and Xuan Financial into the Sun Destroying God Wheel.

But Zhang Yuchen discovered a problem: Xuan Iron and Xuan Jin could not integrate into the Sun Destroying God Wheel.

As an innate immortal weapon, the Sun Destroyer God Wheel has its own consciousness. The integration of other matters makes the Sun Destroyer God Wheel repulsive. Unless Zhang Yuchen has the ability to melt and re-shaped the Sun Destroyer God Wheel, it is impossible to put Xuan Iron and Xuan Financial into the Sun Destroyer God Wheel.

"What should I do?" Zhang Yuchen frowned. After a long time of work, his true energy was exhausted. He still had not integrated the two top-level refining materials into the Sun-Destroying God Wheel. Zhang Yuchen had no choice but to give up and put away the materials.

"It seems that only by finding a way to melt the Sun-Destroying God Wheel can these materials be integrated." As he said that, Zhang Yuchen took out a Yuan-Entering Pill and swallowed it, sat in place and meditated to restore his true energy. Then, Zhang Yuchen sacrificed his flying sword and left the Immortal Island directly.

The Pacific volcanic group is the largest active volcano in China. It is 300 miles in a radius and is all volcanoes. Zhang Yuchen came with his sword and flew directly into the largest volcano.

This volcano is located in the center of the entire volcano group. It is an active volcano. Two hundred meters down the abdomen, it is bubbled magma.

"The fire-attribute spiritual energy here is so rich, it is a good place for cultivation, but it is too far from the Immortal Island, so it is inconvenient to go back and forth." Standing above the crater, Zhang Yuchen smiled helplessly. If he practiced in such a place, his cultivation would definitely improve very quickly. However, this place is too far from the Immortal Island, and it takes five days to go back and forth. The Immortal Island cannot be without him.

"The temperature below this volcano is close to ten thousand degrees, which should be able to melt the Sun-Destroying God Wheel!" Zhang Yuchen entered the crater and found a place to settle down.

"It's so hot. The temperature at the magma mouth has reached more than 500 degrees. If I hadn't been a fire-attributed cultivator, I'd probably not be able to stay here for a long time!" Zhang Yuchen showed a hint of solemnity. He was so hot that he would have been out in the last few hours.

The Sun Destroying God Wheel was sacrificed to allow it to slowly enter the magma. The magma temperature on the skin was only more than one thousand degrees, and it was impossible to melt the Sun Destroying God Wheel.
