Now that this piece of iron is so difficult to refine, the beating of external forces is no longer enough to get rid of all the impurities in it, so it can only strengthen the flames. The flame of the Tianding Sect is enough to refine the medicine, but the refining weapon is still a little worse.

Su Yang looked at the dark red piece of iron while thinking about countermeasures in his heart. The flames generated by the fire talisman were already his strongest fire for Su Yang now, and they were a little hotter than the flames condensed by his vitality.

Not even this fire, Su Yang couldn't think of what kind of flame could temper this piece of iron for a while.

"Boy, since there is no way to increase the power of the flame, why don't you want to increase the purity of the flame? Your fire talisman contains samadhi true fire, although there is only a trace of it, but if you can extract these samadhi true fire, the samadhi true fire among the hundreds of fire talismans, are you afraid that you can't refine such a piece of mortal iron?"

Just as Su Yang was racking his brains, the Spirit Elder in the Sea of Consciousness suddenly spoke. When Su Yang heard Elder Ling's words, his heart suddenly moved, and his eyes lit up.

But immediately, Su Yang groaned again, although purifying the flames in the fire talisman could indeed solve the problem of refining this piece of iron.

But refining the flame is easy to say, but it's a different thing to do. Su Yang himself was not a fire attribute cultivator, and he knew almost nothing about flames, how could he purify the fire talisman flames?

Sensing Su Yang's thoughts, Elder Ling continued, "Boy, do you still remember the method of condensing soul fire that the old man taught you back then?"

Hearing Elder Ling say this, Su Yang suddenly remembered that when he was still in the Ghost Cultivation Domain, in the body of the Falling Soul Mountain, he gathered those soul fires that were originally weak through continuous compression, and finally formed a powerful fireball.

Thinking of this, Su Yang's heart moved, and he blurted out: "What does my predecessor mean is that I can extract the Samadhi True Fire in these fire talismans by constantly suppressing them with my vitality?"

"Yes, this fire talisman is made by condensing all fires and adding a trace of samadhi true fire to them. After the energy is compressed, all the fire is fragile and will inevitably dissipate, and the true fire of samadhi will reveal its true body. Moreover, after compression, the purer energy in the mortal fire will also be absorbed by the samadhi true fire, in this way, although the obtained samadhi true fire is still not pure, it is enough to purify this piece of iron!" said the spirit elder lightly.

After Su Yang understood, a hint of joy suddenly flashed on his face, because he already understood that the method that Elder Ling said was definitely successful.

At this time, Su Yang became even more curious about Elder Ling, it seemed that Elder Ling was not just a demon in Qu Tian's mind as he said.

If it's just a demon, you won't be so knowledgeable. As for what he said that he had read the many classics of the Immortal Sect, it was obviously an excuse, Su Yang did not believe that a sect of cultivation in the Underworld could understand the secrets of the cultivation of the Three Realms!

Of course, now is not the time to think about that. Su Yang put his finger on the pulse, and found that the pulse speed was steady and slow, and it was obvious that it was already night. Five days have passed one day, and the remaining four days still need to purify, condense, temper, shape and a series of work such as iron blocks, and the time is already very urgent.

Su Yang asked the soul slave to take out two more fire talismans to ignite them, maintaining the temperature in the furnace, and then began to take out all the fire talismans in the soul slave's body, letting them suspend in midair.

Running his vitality, Su Yang slowly wrapped all the fire talismans suspended in front of him, and then suddenly ignited all of them.

In an instant, the temperature in the entire casting room soared, and the flames that were more than one person tall were burning in front of Su Yang. If it weren't for Su Yang's vitality to shroud all the fire talismans, I'm afraid Su Yang would have been burned a long time ago.

And even so, this raging flame was also quickly consuming Su Yang's vitality, and Su Yang was already sweating slightly on his forehead.

He constantly urged the Yuan Qi in his body, because the sword Qi had the effect of absorbing and devouring this flame, so Su Yang did not dare to use the sword qi, but relied on the pure Yuan Qi to envelop the flames.

The Yuan Qi that was originally shining with a faint golden light turned fiery red under the reflection of the flames, and Su Yang's hand seals changed rapidly, constantly making the Yuan Qi shrink and shrink again.

Gradually, the flame, which was more than one person tall, became only half a person high, but the temperature in the casting chamber did not decrease as the flame decreased, but seemed to be higher. Su Yang knew in his heart that after the flame was compressed at this time, the energy became pure.

He didn't dare to be careless, and urged the inner pill in his body to run rapidly, because after entering the Dancheng stage, the two inner pills were yin and yang, and Su Yang's vitality became more vigorous. Therefore, in the face of such a flame, he can finally control himself. If he was still cultivating in the Yudan period, I am afraid that he would only be able to hold on for two or three times, and Su Yang would be devoured by the flames.

The flames continued to grow smaller, and when the flames became the size of a pot, they suddenly developed a strong resistance force. This resistance was also there before, but after all, it was very small, who knew that it would increase dozens of times in an instant, if it weren't for Su Yang's repeated care, I am afraid that this time the vitality cover would be broken.

But Rao was like this, the vitality shield controlled by Su Yang still flickered a few times, and his vitality was suddenly consumed.

Seeing this situation, Su Yang became more cautious. Almost a little bit of his vitality power was slowly added, constantly suppressing the flames.

At this time, the flame was no longer red, the color had faded, and there was a faint hint of gold. Su Yang knew that the change in color naturally represented the change in the power of the flame.

Time passed little by little, and Su Yang controlled the vitality to continuously compress the flame, and at this time, the flame was still only the size of a skull. There is no trace of light red in the flames, and the color is extremely light.

Rumble!

Suddenly, a gentle roar suddenly erupted from the flame wrapped in Su Yang's vitality, and the flame that was originally the size of a skull shrank violently, and finally turned into a fist-sized flame. The tyrannical aura of it also disappeared, leaving only an endless scorching breath.

It's done!

Su Yang was happy in his heart, he couldn't feel any unstable aura at this time, although the whole flame didn't look as terrifying as before, but judging from the temperature it emitted, it was far from being comparable to the previous flame.

After completing this, Su Yang's eyes flashed, and he already realized that this condensing flame had actually taken him a day. In other words, so far, Su Yang only has three days.

I saw Su Yang suddenly grow up, and he didn't care about recovering his vitality, so he held the flame with the palm wrapped in his vitality and slowly sent it into the furnace.
