"It's... Iron Spirit!"

Although most of the body refiners around Jiang Xian had never seen iron essence, they had long heard of this famous treasure of refining weapons, and it was said that only adding a grain of iron essence to the weapon would greatly increase the level of the weapon. However, although the iron essence has a wonderful use, it is very difficult to refine, even if the true fire of the immortal cultivator in the foundation building period wants to refine such a small grain of iron essence, it will take a lot of effort.

Therefore, the iron essence was very precious to the body refiner, and everyone looked at the grain of iron essence in Jiang Xian's hand and could not hide the surprise and greed in their hearts.

"What is this, you must all know it, right?" Jiang Xian glanced at everyone and suddenly spoke.

Lin Tian and the others all nodded firmly.

"What is the key to the success or failure of the refiner, which of you will tell me?"

There was a brief silence in the refining room, not that these people didn't know the answer, but at this time, no one dared to show off their weak alchemy.

"It's the materials and the fire control. Seeing that the atmosphere was a little wrong, King Shao and Wang on the side couldn't help but glance at each other with a wry smile, and finally Senior Brother Shao broke the peace.

"That's right, it's fire control and the selection of materials. Jiang Xian said expressionlessly, "Fire control is the most basic prerequisite for a refiner, if it is only the refiner's fire control skills are ordinary, and the spiritual flame used is also very ordinary, at most he can only refine ordinary low-grade divine weapons, if the refiner's fire control skills are more sophisticated, he can refine medium-grade divine weapons." However, no matter how clever the refiner's fire control technique is, the quality of the spiritual flame used can't keep up, and he can't refine the top-grade divine weapon. ”

After hearing this, everyone around suddenly showed thoughtful looks, but most of the people's faces were normal, and only a small number of people's faces couldn't help but change.

For example, Lin Tian, he had never heard of such a secret before, and he didn't know how to do it, and the notebook that Mo Yan gave him did not record this kind of thing.

Thinking of this, Lin Tian couldn't help but touch the Chulu Sword on his body, when refining the Chulu Sword, Lin Tian used the fire of Tianyue Peak's lungs, if he used the strange flame in his hand, I don't know if the Chulu Sword would directly step into the ranks of the high-grade divine soldiers.

Although Lin Tian wasn't sure if that strange flame was the legendary immortal flame, the quality was definitely much higher than the earth fire on Tianyue Peak.

"Fire control and spiritual flame are only one of the basic conditions for refining weapons, and in order to refine a good divine weapon, the materials used are equally important. Jiang Xian paused for a moment, then continued, "If it's just an ordinary material, even the world's top-level refining master can't go beyond the scope of ordinary weapons. Just like the difference between refining spirit tools and refining high-grade divine weapons, that is, all spirit tools have at least one grain of iron essence!"

The people around fell into silence again, all thinking quietly.

Suddenly, Senior Brother Shao on the side raised his head and asked with a nervous expression, "Master, do you have to add iron essence to refining magic weapons?"

"Yes, a little. Jiang Xian nodded affirmatively, and there was a hint of regret in his gaze when he looked at him.

Senior Brother Wang on the other side was puzzled by Senior Brother Shao's actions at first, but after hearing Jiang Xian's answer, he suddenly thought of something, and his face turned pale in an instant.

The changes in the two of them couldn't help but make everyone around them wonder, staring at each other with big eyes, not knowing what they meant.

"You two don't have to be too sad, now that you have cultivated to the peak of the seventh level of body refining, as long as you go further, you can break through to the eighth level of body refining, and when the time comes, you can also be a senior brother of the flame wolf, and it will be no longer a problem to refine the magic weapon. Jiang Xian comforted softly.

At this time, Lin Tian finally understood, if you want to refine a magic weapon, you must add iron essence, but to quantify iron essence, the requirements for spiritual flame are extremely high, listening to Jiang Xian's meaning, it seems that it is only possible to reach the level of spiritual flame of the flame wolf natal primordial fire in front of him, but this level of spiritual flame is not something that ordinary body refiners can control.

"No wonder the two of them have such expressions, it's not that their alchemy skills are not superb enough, but their own strength is not enough. Unless the two of them can cultivate to the eighth level of body refining, but how can the eighth level of body refining be so easy to break through, it is said that there are only five or six people above the eighth level of the entire Haoran Pavilion's body refining body. Lin Tian looked at the two Shao Wang opposites and thought of it with some pity, but he couldn't help but shake his left hand.

After that, Jiang Xian didn't say anything, but concentrated on refining the weapon, the blood-red spiritual flame was matching his own samadhi true fire, and the iron essence was melting rapidly at a speed visible to the naked eye, and it was well fused with other materials...

After a while, the shape of a golden knife gradually formed in the furnace, and slowly solidified under Jiang Xian's control.

"Ning..." Jiang Xian shouted, the magic trick in his hand changed, and the flames surrounding the golden knife disappeared in the blink of an eye, and the golden knife roared, and the strong light around his body was great, and the edge was revealed!

However, Jiang Xian's face was not the slightest relaxed, but there was an unprecedented solemnity, his hands were changing rapidly, and mysterious runes and strange patterns appeared strangely between his hands.

The index finger of his right hand flew forward a little quickly, and these runes and patterns suddenly swarmed towards the golden knife above, as if it was a teasing, and he circled around the golden knife twice, and then attached it to the golden knife with lightning speed.

The "Buzz" golden knife shook violently, and with a "boom", it broke free from the shackles of the furnace and turned into a golden streamer, which flashed in the fast refining room.

The dazzling golden light suddenly exploded, and the startled Lin Tian and the others hurriedly closed their eyes, and when the golden light dissipated and Lin Tian opened his eyes, the golden knife had already fallen into the hands of Jiang Xian, who was expressionless.

"Go and test the power of this golden knife. Jiang Xian handed over the golden knife to Senior Brother Shao's hand on the side.

Senior Brother Shao looked happy with the golden knife, gently walked to the test stone on the other side of the refining room, held the golden knife tightly, and suddenly swung forward, a golden blade more than a zhang long spit out from the top of the golden knife, a sharp voice sounded in mid-air, and the hard test stone turned into two halves in a surprised gaze...

"Sizzle" came out with the sound of gasping for air.

"I'm afraid the quality of this spirit tool is not ordinary!"

・・・・・・

After observing the refining weapon for a while, Lin Tian won Jiang Xian's trust by refining a few medium divine weapons of good quality, and completely gained a foothold in the Treasure Refining Hall.

But now Lin Tian has an extra pimple in his heart, the power of the golden knife last time really shocked him a lot, now his strength is low, in the cultivation realm where the flesh is weak and the strong eat, if there is a spirit tool in hand, it will definitely be much safer. Especially during this period of time, there were more and more high-level body refiners in Jianyuan City, and Lin Tian also faintly felt that something important was about to happen.

frowned slightly, took out a package from his side, opened it gently, and more than a dozen shiny metal particles lay quietly in it, if outsiders saw it, they would be surprised, these things turned out to be all iron essence. These iron essences were all secretly refined by Lin Tian when he was at Tianyue Peak.

Now Lin Tian's contradiction in his heart is whether to use the iron essence to refine the Chulu Sword again, don't be surprised, if for other body refiners below the eighth level, refining the iron essence is just a luxury, but for Lin Tian, it is not much of a difficulty, because he clearly feels that with the strange flame in his hand, he can do it at any time.

And he was confident that as long as he could integrate the iron essence into the Chulu Sword, he would have at least half the certainty of raising the Chulu Sword to the level of a spirit tool.

But what worries him is that if his Chu Lu Sword suddenly turns into a spirit tool is discovered by others, then he can't explain it clearly, and this possibility is very big.

Tightly frowning, Lin Tian thought about it for a long time, sighed slightly in his heart, and still put away the iron essence in front of him, canceled this thought, and was still careful and subtle.

However, Lin Tian was not idle, although he could not upgrade the Chulu Sword to the level of a spirit tool, but it was still possible to upgrade to the level of a high-grade divine weapon, after all, this kind of change was not big, it was not easy for others to notice, and even if he found it, it was very easy to get by.

After making up his mind, Lin Tian didn't hesitate much, and with a flip of his left hand, a lotus-shaped spiritual flame gently emerged, staining the Chulu Sword, and the Chulu Sword melted rapidly, while Lin Tian kept putting some of the other refining materials he had collected into that spiritual flame...

The night passed in a hurry, Lin Tian touched the Chulu sword in his hand in surprise, at first glance, it was not much different from before, but after a closer look, he found that the sword body seemed to be thinner than before, but the sharp aura on it was a little stronger...

A few days later, there was good news that Lin Tian had inquired about Lingyan in many ways, and finally there was news...
