Chapter 247

The quality of those two long spears is not low. Even if they have been melted into liquid, it still takes a lot of work to completely extract the essence inside.

Especially temperature control.

The key to the method of refining stars is refining. If the temperature is higher, the essence inside will be evaporated directly, and if the temperature is lower, the essence cannot be extracted.

Therefore, how to control the temperature within a certain time range has become the key to the success of star refining.

And each kind of treasure needs different temperature after smelting, there is no fixed value among them, we can only explore it slowly by experience.

This requirement seems to be excessive, but for Feng Qingyu who has many successful experiences, it is not too difficult.

As long as you find out where the ball of molten metal is receiving, it won't be difficult to extract its essence.

It's just that what Feng Qingyu didn't expect was that such a simple question became a natural barrier in front of her.

She couldn't extract the essence of this molten metal!
Feng Qingyu was really speechless as the molten metal that had been smelted so hard could not extract the essence.

She tried various levels of temperature, but she couldn't find the melting point of the liquid metal essence.

How can this be done?

The two long spears have been fused like this, and it is impossible for her to return to her original appearance.

She understands the method of refining stars, but not the way of refining tools. The longer the molten metal is left, the faster the essence will evaporate.

If it can't be extracted before the essence inside evaporates completely, then this ball of molten metal will really turn into lumps of iron!

Feng Qingyu was so anxious that she desperately searched for a solution, and then she found sadly that it wasn't that the molten metal couldn't extract the essence, but that the temperature of the golden flame was not enough!

"It's crazy enough, the temperature of this flame can burn up a mountain, and it hasn't reached the melting point yet! Jin Yan, you try it!" While speaking, Feng Qingyu had already conveyed her thoughts.

But Jin Yan, who was hiding in the gray stone, was reluctant to do so, but reluctantly left his new home and came to Feng Qingyu.

"Into the flames, I want to see if this thing can resist your burning!"

As soon as the words fell, Feng Qingyu pointed out that Jin Yan's original figure shook and completely merged into the flames.

The integration of Jin Yan's origin immediately increased the temperature of the flame, and the color of the molten metal became more lustrous, but that was all.

After that, no matter how hard Feng Qingyu tried, the molten metal did not change much.

"I can't refine it if I don't believe it!"

After paying such a high price, now that she is stuck at the juncture of insufficient temperature, Feng Qingyu really struggled.

The little knife is just looking at it eagerly at the entrance of the cave. If this stall tells it that she can't extract the essence and liquid, it will definitely explode!
No, it took a lot of effort to suppress its arrogance. If it knows that it can't do anything with this ball of metal liquid, maybe it will use some words to run her down!
"Is there any way to increase the temperature?" Feng Qingyu desperately mobilized her vitality while transmitting sound to Jin Yan.

Jin Yanyuan hesitated for a while, and then sent a thought to Feng Qingyu, asking her to take out the gray stone and hand it to him.

Huishi couldn't enter the Sea of ​​Consciousness, so Feng Qingyu carried it with him.

Jin Yan didn't go with her when she went out before, so she also left the Huishi behind.

Now the gray stone is lying in the corner of the cave, but Feng Qingyu doesn't know what Jin Yan asked her to do with the gray stone.

As soon as the vitality in the palm was retracted, the gray stone had been taken into Feng Qingyu's hand.

Picking up the gray stone and glanced at it, Feng Qingyu threw it to Jin Yan.

The moment the gray stone was caught, Jin Yan's original source immediately rose, and the flames surrounding the molten metal also boiled together. It seemed that the gray stone contained some kind of energy, which could stimulate the potential heat of the flame.

Seeing that this method was effective, Feng Qingyu hurriedly increased the output of vitality again, but at this time, Jin Yan's original source sent out an idea again, telling her to only pay attention to controlling the temperature, without using real energy to help it.

With this piece of gray stone, it will bring the temperature to the standard that Feng Qingyu wants.

Silently withdrawing her vitality, Feng Qingyu only used her soul power to monitor the reaction of the ball of liquid metal, and left all the rest to Jin Yanyuan.

The flame energy released by the source of the flame is far more powerful than that released by her cultivator.

As soon as the gray stone was submerged in the flames, its color turned crimson, and countless small holes were exposed on its originally smooth surface.

Those holes are densely covered like honeycombs, and Jin Yan goes in and out of the gray stone through these holes.

It's still strange, she used her spiritual sense to check carefully several times before, but she didn't find any holes in the stone.

Including every time Jin Yan came in and out of this stone, Feng Qingyu thought they were of the same attribute and automatically blended together, never thought that Jin Yan drilled into the stone through these holes.

Jin Yan was submerged into the stone at its core, and the temperature of the flame rose rapidly, but within the breath, the temperature reached an extremely terrifying level.

According to Feng Qingyu's estimate, even the flames in the middle of the heavenly rank may not be able to reach this temperature, and it is really surprising that Jin Yan can raise the temperature to such a level with just this small piece of rock.

You must know that after the heavenly rank, whether it is flames, beasts, or demons, every step of advancement is extremely difficult.

Without hundreds of years of energy accumulation, it is impossible to enter the next stage, but this stone that does not even have a grade can make Jin Yan suddenly break through the middle stage of the heavenly stage. Although this is only temporary, it is really abnormal enough.

As soon as the mind wandered away for a moment, the ball of metallic liquid had already started to become extremely hot, and wisps of black smoke rose from it from time to time.

Seeing this scene, Feng Qingyu didn't think too much, and concentrated her mind and began to practice.

As the temperature rises, it is not so difficult to extract the essence. As long as the temperature is controlled well and the temperature does not fluctuate too high or too low, the black smoke will continuously overflow from the molten metal.

When the black smoke no longer appears, the preliminary refining has been completed.

It's just that the essence at this time is not pure enough, and it needs to be tempered repeatedly with low fire.

And this tempering process is also the most tormenting.

Feng Qingyu needs to integrate her soul power and thoughts into the flames, and observe the reaction of the essence all the time, so that the temperature of the flame cannot be increased by one point, and she must ensure that the temperature inside and outside the essence liquid is exactly the same.

At this time, Feng Qingyu's spirit must be highly concentrated, not to miss the slightest change, and always pay attention to the overflow of impurities and the reaction of the essence liquid to the flame.

For the whole three days, Feng Qingyu spent in this extremely boring and exhausting state.

Because of staring at her for too long, her bright eyes were bloodshot.
