The sunken eyes moved towards Elder Manbo, but he only saw his expression focused on his furnace, his body and mind were completely immersed in it, without any disturbance from Houshan beside him.

At this moment, he had sent Lingxiao's copper and light stone into the furnace, controlling the flames to form three rings, surrounding the two materials in the center, trying to melt them together.

The temperatures of the three flame rings vary. They cycle back and forth and continuously rotate around the two spiritual materials. The two materials are fused at different levels through alternating flames from time to time.

This method of fusion has been seen in the Tianji Book of Treasures. It is called biting and smelting. It is a very difficult method of smelting. It is more complicated than simple smelting and kneading, but it can better retain the advantages of both spiritual materials. The refined sulcus also has more high-quality characteristics.

For example, the Lingxiao copper has excellent ductility but insufficient toughness. If it is simply fused, the spiritual material formed can indeed enhance its toughness while ensuring ductility, but the synthesis effect is only equivalent to another more advanced spiritual material, the gold of the sea.

But if it is made by occlusion and smelting, the two spiritual materials will be interlocked, stacked and fused, and their ductility and toughness will be better than the gold in the open sea.

Hou Shan, who was beside him, saw that Elder Man Bo had mastered the method of biting and smelting, an jealous look appeared in his eyes, and the tips of his eyebrows drooped slightly.

In this regard, he is no longer as good as Elder Manbo...

At this time, he also put away his contempt for Elder Man Bo and began to focus on refining Yan Jia.

As time goes by, the main metal in the gold-scaling furnace has been refined and turned into a liquid state, which is controlled by it to be suspended in the furnace chamber with its magic power.

After a moment, wisps of smoke began to emerge from the melting liquid, which was a sign of separation of impurities contained in it, indicating that the purity of the spiritual material was constantly improving.

Chen Luo looked at his movements, and the voice of Huo Lingzi suddenly sounded in the sea of ​​consciousness: "In this case, the elder Barbarian might lose."

In his hand hidden in his sleeve, he was holding the Xiaoyao Mirror.

The water clouds lingered on the mirror, and the Nether Fire Refining Furnace was reflected inside, and the Fire Spirit Son was also living in it.

"This is only the smelting stage, and you can already see the result?" Chen Luo's expression did not change at all, and he asked with his mind and mind.

"Although the method of biting and smelting by Elder Man Bi is good, the furnace used is really ordinary, which causes the furnace fire to heat up quickly enough, and it is impossible to make the spiritual material biting and smelting to the flawless state. On the other hand, Hou Shan is different. The spiritual material he melts can basically reach the flawless level, which is better than that of Man Bi." Huo Lingzi said.

"It's just that the difference in the purity of spiritual materials is not enough to determine the outcome, right? Besides, the method of biting and smelting is obviously better." Chen Luo hesitated.

"No. Although Houshan's smelting method is ordinary, because it is a target, it does not require high ductility and has more flexibility, so there is no need to ensure more ductility. It is also because of this that I dare to conclude that the shape of the instrument he refined must be Yanjia, which has lower ductility requirements, such as short daggers and short cones, and does not believe it?" Huo Lingzi said confidently.

Chen Luo didn't say anything, but saw that the other side of Houshan had begun to add auxiliary materials to the furnace.

As several auxiliary materials flew into the furnace one by one and fused with the main materials one by one, the temperature in the furnace began to gradually drop.

At this time, Hou Shan's hands began to dance in the void. The melt of the spiritual material in the furnace began to gradually solidify as the temperature decreased, revealing its true form of armor little by little. As Huo Lingzi said, it was a triangular short cone.

"It is not easy to be able to refine such a erectile sculptural form in such a short time. As long as there is no problem with the erectile sculptural engravings behind it, he may be sure to win." Huo Lingzi said in a voice transmission.

Chen Luo couldn't help but frown when he heard this.

If Hou Shan really wins this game, then Che Qingtian and the others will win two games in a row and win directly.

He couldn't help but look at Elder Manbo with concern.

Compared with Hou Shan, his speed was much slower. He has not been able to refine all the spiritual materials yet, and he is still adding spiritual materials to the furnace.

Almost everyone could see that his firepower was insufficient, and he was slower one step, slower one step.

But at this moment, he suddenly selected a very inconspicuous fire flint from the many spiritual materials, which was unexpectedly selected from everyone and sent into the furnace with magic power.

"I'm afraid it's useless to add fire flint to it now. What does this guy Man Bo want to do?" Elder Fu was a little anxious.

This thing is usually used as a combustion-enhancing material, which can increase the fire temperature to a certain extent, but when added at this time, the effect will be a bit useless.

However, he saw that the fire flint was wrapped in his magic power. After entering the furnace, it did not burn immediately, but was controlled by it and suddenly accelerated and rushed into the molten spiritual material liquid.

The fire flint was immediately completely wrapped up as soon as it entered the spiritual material liquid ball.

Everyone was confused when they saw this, but Huo Lingzi's eyes suddenly lit up, as if they had thought of something.

Immediately afterwards, a dull sound of "boom" was heard!

The melt of the spiritual material suddenly expanded, swelling like a balloon, and a large amount of white mist suddenly surged out on the surface.

After a moment, the white mist completely dissipated, and the swelling molten spiritual material slowly opened, revealing a ball of black fire flint ash from it, which was slowly peeled off.

"Genius, genius, is really a genius' approach." Huo Lingzi couldn't help but exclaim.

"How do you say it?" Chen Luo couldn't understand it for a while, so he asked in a voice transmission.

"I underestimated Elder Man Bi. He could actually think of the method of using the internal detonation of the fire flint to instantly increase the melt temperature of the spiritual material, and then evaporate the impurities in the melt. It is simply a genius." Huo Lingzi was still quite excited.

Chen Luo also understood after hearing this, and at the same time, he also realized that the difficulty of this operation was extraordinary.

After all, the temperature of the fire flint deflagration must be controlled to be high enough, and the power of the fire flint deflagration must be ensured is not enough to break through the blockade surrounded by the melt. At the same time, the embers after the fire flint deflagration must be controlled with mana to prevent them from entering the melt for secondary pollution.

Such a meticulous operation, Chen Luo thought he was not able to achieve his ability yet.

After the melting of spiritual materials was completed, the temperature of Elder Manbo's furnace began to gradually drop, and a round shield shape was gradually forming.
