Heifengtianzong's mental power shrouded the two pieces of Yanyang ore, and their fineness was almost the same. Although the volume was more than ten times larger than the previous Yanyang ore, the proportion of impurities was much less.

"I'll just use this." Hei Fengtian casually pointed at a piece.

Master Feng nodded, exchanged glances with Master Jin, and the two began to smelt.

The Yanyang ore, which was half a person tall, was dropped on the operating table with a casual move by Master Feng.

Um? Late Huang Ling?

A bit of surprise appeared in Ye Yuxi's eyes, she hadn't noticed it before, but now that Master Feng made a move, Ye Yuxi immediately sensed the old man's strength.

On the other hand, Heifeng Tianzong, the ninth-level peak, although his cultivation base is not weak, but that is for people of the same age. Compared with these two old men, there is an instant difference. From the perspective of flame intensity and cultivation base, Master Feng is more dominant. Advantage.

Boom boom boom!

A ball of flames lit up, and a scorching metallic aura rushed over.

Ye Yuxi raised her eyes to look at the smelting furnace, a look of astonishment flashed in her eyes again, metal beast fire!

And depending on the strength, it is somewhat stronger than Tianzong's.

Glancing at Tian Zong, the latter's face was also full of dignity, this Master Feng is a master, stronger than Tian Zong in both cultivation and fire.

Hei Fengtian watched every movement of Master Feng calmly. The forging hammer he used was not one hundred catties, but one hundred and twenty catties!

Every time the heavy forging hammer is swung, there will be a whistling sound.

'Ten years... I can't afford to lose this competition...'

Hei Fengtian's breathing slowed down, and his fists gradually clenched, no matter what, he would win this sparring match.

After two hours, Master Feng's forehead was covered with sweat, and the smelting had reached the final stage.

With the roar of the last flame, the smelting furnace returned to silence.

hiss--

A burst of white water vapor rose, and the finished Sunstone that had just been smelted was rapidly cooled in the water.

"Little brother, it's your turn."

Master Feng held the freshly smelted Sunstone with one hand, and there was still a little bit of warmth on it. With a flash of inspiration at his fingertips, a simple square table appeared, and Master Feng casually placed the Sunstone on it.

Ye Yuxi looked sideways at the Yanyang Stone, feeling a little mental power, Ye Yuxi's heart sank, and she thought to herself: What a pure Yanyang Stone!

This stone is of higher quality than the few boxes I bought.

It seems that Master Feng has really worked hard to keep Tian Zong.

After seeing the finished Yanyang Stone, Master Jin let out a sigh of relief, looked at Heifeng Tianzong as well, and said, "Little brother, it's your turn."

Hei Fengtian looked away from the finished Yanyang Stone, and walked towards the smelting furnace in silence.

After more than two hours of observation, Tian Zong already had a preliminary understanding of this stove.

"Gu Feng, prepare ten catties of cold water." Hei Fengtian ordered in an orderly manner, and Heisha beside him manipulated it skillfully.

As the flames rose, the atmosphere in the stone room became tense.

Master Feng's smelting technique is perfect, almost without any mistakes, otherwise the quality of this Sunstone would not be so high.

After Hei Fengtian saw the finished Sunstone, he knew that unless he refined the top-quality Sunstone, he would not be able to win at all!

"Increase the wind."

Hei Feng Tian Zong controlled the metal flame, and wanted to give orders to Hei Sha in his mouth.

There was a flash of spiritual light in the dark palm, and two white stones appeared in the palm.

Click!

Tian Zong squeezed it hard, and the two white stones were crushed into powder.

In the eyes of everyone, Tian Zong threw the palm of his hand, and the handful of white powder was directly sprinkled into the furnace.
