The door was closed, so that Xue Jin couldn't know what Lin Xun was busy with, but he knew in his heart that refining the war knife this time was very important to Lin Xun.

As early as many days ago, he had heard Lin Xun talk about it, and for this reason, Lin Xun also asked him some information about the structure and characteristics of the war knife.

As a strong man with extremely rich combat experience, Xue Jin naturally saw countless spirit weapon battle knives in his life, but he didn't know that Lin Xun even had to ask himself about this trivial question, so what kind of battle knife did he want to refine?

At this time, looking at the many spiritual materials in the Nine Refining Furnace that were constantly steaming with various colors of brilliant light, and looking at the tweet that was concentrating on controlling the heat, Xue Jin's heart became more and more curious.

He could vaguely feel that the war knife that Lin Xun had refined this time was only afraid that it was completely different from the war knife he had ever seen!

In other words, in Lin Xun's hands, it is very likely that a new type of war knife that has never been seen in the empire will be born!

Thundered~~

As time passed, the Nine Refining Furnace continued to boil, producing a roar like a tidal wave, and the dazzling waves of fire erupted and were dazzling.

It can be clearly seen that all kinds of spiritual materials have begun to melt gradually at this time, turning into red, indigo, blue, white, water green, purple and other colorful and illusory liquids, which are so beautiful that people tremble.

It was the first time that Xue Jin had witnessed this process of smelting spiritual materials, and he couldn't help but be stunned when he saw such a strange and dreamy scene.

This is the method of the Spirit Tattoo Master!

Turning decay into magic, like a miraculous workmanship, the creation of heaven and earth, so that the various spiritual materials that originally seemed inconspicuous suddenly showed a strange taste.

Whew~Whew~~

Every once in a while, Jiu Jiu would spew a mouthful of Shattered Star Golden Fire into the Nine Refining Furnace, although the little guy said that it was the first time to do this, but now he was able to skillfully control the fire, and even under its control, the temperature of the spiritual fire in the Nine Refining Furnace was perfectly maintained in an optimal state.

This made Xue Jin, who was originally quite worried in his heart, completely relaxed, as he said before, Jiu Jiu, who has a broken star golden fire, is a natural smelting master!

Other smelting masters in this world also need to use complex spirit pattern arrays to control the temperature of the spiritual fire, and the higher the quality of the spiritual fire, the more difficult it is to control, which brings a great burden to the smelting master.

Like a heaven-level spiritual fire, it often requires the cooperation of several smelting masters to fully control it and bring out the best use of it.

But for Jiu Jiu, there is no need to be so troublesome at all, the Shattered Star Golden Fire, which can be called a rare heaven-level spiritual fire, is like a part of its body, and it can be completely controlled by it as it wants.

The comparison between the two suddenly brings out the cleverness of the tweet.

Xue Jin was even thinking that if those old guys from the Imperial Academy knew the power of tweeting, he was afraid that his eyes would be red with jealousy.

Thinking about it like this, time passed quickly, and before you knew it, night was coming.

The various spiritual materials in the Nine Refining Furnace had already been completely melted, and all impurities had been smelted and removed, leaving behind the purest essence.

At this time, Jiu Jiu didn't know how many mouthfuls of broken star golden fire he had spewed, and he was obviously a little weak, and his round body like a ball was constantly gasping, as if he would fall down at any time.

But the little guy showed a tenacious tenacity at this moment, and his dark round eyes were full of concentration.

This made Xue Jin feel distressed and surprised, but he didn't expect that this stupid and cute little guy would be so ruthless, just like Lin Xun's kid.

If it weren't for Jiu Jiu being a spirit beast, Xue Jin would have doubted whether it and Lin Xun were father and son.

Rumble~

Suddenly, there was a strange sound in the Nine Refining Furnace, and the various spiritual materials that had been completely smelted into juice were shrouded in a spirit pattern at this moment, producing an astonishing change.

Xue Jin's eyes widened suddenly, and he saw that in the furnace, a strangely shaped war knife embryo was gradually taking shape, the fire was thick, and the spirit patterns flowed, looking mysterious and dazzling.

At this moment, the door that had been closed for a day was opened, and Lin Xun strode out, and when he saw this scene, a flash of brightness flashed in his dark eyes.

"Chirp, it's okay. ”

Lin Xun said a word, tweeting as if relieved, he took a sharp breath, and swallowed all the shattered star golden fire in the Nine Refining Furnace back into his stomach.

At the same time, Lin Xun pinched a spiritual trick, and in the rain of light, the Nine Refining Furnace suddenly stopped running and fell silent.

Xue Jin couldn't help but come closer, and when he saw Lin Xun carrying it casually, he took out a war knife from the furnace that was two feet seven inches long, four fingers wide, and completely black.

It looks ordinary, but the blade is quite unique, the blade is as thin as a cicada's wings, the edge is shaped like a perfect arc, and in the center of the blade, there is a straight blood groove, reaching the tip of the knife, as if you want to drink blood!

Xue Jin's eyelids jumped, just looking at the shape, he knew that this knife was a murder weapon, the perfect arc of the blade, and a blood groove opened by the blade, all in order to kill the enemy more effectively and directly.

Overall, compared to other more exaggerated and hideous knives, this knife is not amazing, and even looks ordinary.

But when you look closely, you will find that although this knife has not yet been engraved with a spirit pattern, it is not a real spirit weapon, but the blade has shown a kind of fierce aura!

Like a dormant beast, once awakened, it will drink blood!

What kind of war knife is this?

Xue Jin couldn't help but be curious, but when he wanted to ask, he saw that Lin Xun had hurriedly returned to the room with the embryo of the war knife forged by this disease.

Bang!

The door was closed, cutting off Xue Jin's gaze, making him stunned for a while, could the spirit pattern masters at work all have this virtue?

"Chirp~"

Chirp is like a paralyzed dough, lying on the ground gasping for breath, making a weak chirping sound, looking exhausted and exhausted.

Xue Jin was distressed for a while, and secretly scolded Lin Xun for having no conscience, and left without saying a word with the war knife, not knowing how to feel sorry for the great tweet, it was simply too unconscionable.

If it weren't for Jiu Jiu's help, how could he have smelted the battle knife embryo so quickly?

"Come on, come on, drink. ”

Xue Jin scratched his head, took out a vat of soul-burning wine and handed it over.

Chirp shook his head, looking at Xue Jin pitifully with pure black eyes.

Xue Jin was stunned, and hurriedly took out a piece of Qingyi Spirit Crystal and stuffed it into Jiu Jiu's mouth.

The little guy immediately let out a cheer, and with a click, he swallowed this high-quality precious spirit crystal worth a hundred gold coins into his little stomach.

Immediately, it jumped up, and the fire around it was steaming, and it kept chirping and screaming, happy like a child.

Xue Jin couldn't help laughing, but when he thought that all this was originally done by Lin Xun, but he, a spectator, paid a piece of Qingyi Spirit Crystal for this, his face suddenly became a little ugly.

He looked at the tweet, but muttered in his heart, "Should it be...... That kid has already calculated on Lao Tzu's head, otherwise how could he be so calm when he saw Jiu Jiu so weak just now......

......

This time Xue Jin really wronged Lin Xun, like other spirit pattern masters, once he started working, Lin Xun completely devoted his mind to refining the weapon like never before, and there was no trace of distraction in his mind, and it would not be an exaggeration to say that he was completely forgetful.

Just like at this moment, he sat upright at the desk, picked up the seal pen with a wave of his hand, dipped it in the spiritual ink that had been prepared earlier, and began to carve the spirit pattern on the embryo of the war knife with all his heart.

This time, Lin Xun tailor-made the war knife for himself is a kind of innovation that has never been done before, whether it is the material of the war knife, or the spirit ink required for seal carving, and the spirit pattern required for seal carving, all of them are conceived and finalized by himself.

Every subtle step has been repeatedly deduced by him countless times, in order to prevent any mistakes in the refining process.

After all, this time refining the battle knife, there is no experience to follow at all, everything has to be done independently by himself, once he makes a mistake, all the hard work and preparation he has put in before will be in vain.

Lin Xun is a spirit pattern master who is extremely strict with himself in the spirit pattern, and this quality is inherited from Mr. Lu, so that he will be fully prepared before every time he refines the weapon.

As the saying goes, the mentality of being picky and pursuing perfection is the supreme belief that every spirit tattoo master fulfills throughout his life.

Boom~~

The seal pen waved, and the pen blade was like flowing water, outlining a mysterious and light spiritual pattern trajectory, like a slowly blooming firework, imprinted on the surface of the sword.

Lin Xun's brushwork is calm and simple, faintly with the luck of towering mountains, but the movements are ethereal and wanton, with the style of the Hanhai rushing.

This is a kind of pen power and style formed after countless times of tempering when I was a child, countless times of self-harsh correction, and countless times of reprimands and guidance from Mr. Lu.

All this allows Lin Xun to maintain an unprecedented precision, conciseness and agility when carving the spirit pattern, and can maximize the compatibility between the spirit ink and the perceptual power, so as to make the spirit pattern carved by the seal produce the greatest use.

It's just that all these seal carving spirit patterns are different from the past, Lin Xun has prepared a full forty-nine spirit patterns, the so-called avenue fifty, Tianyan forty-nine, one of the people, forty-nine, the secret cycle of the technique.

In order to make these forty-nine spirit patterns echo and fit each other, it is undoubtedly extremely difficult for Lin Xun today, far more than before.

However, at present, everything is still under Lin Xun's control.

Time flies, the sun rises and the moon sets, and before you know it, three days have passed.

Lin Xun didn't eat, drink, sleep, and maintained the same posture, and now he has carved a full forty-eight spirit patterns.

He was refining the last Spirit Pattern.

It's just that his face is pale at the moment, sweat is faintly soaking from his forehead, and although his gaze maintains his usual concentration and calmness, it is obvious that he is about to lose his support.

And in his body, the incomparably strong spiritual power was already on the verge of exhaustion, and the soul perception power was also seriously consumed, and from the inside out, there was a taste of the end of the strong attack.

The situation is indeed serious!

Up to this time, Lin Xun has pushed the things he has performed, and when he really puts them into practice, the situation that appears is far more complicated and difficult than he imagined!

Even, if you can't hold on at this moment, all the previous efforts will be in vain!
