When Cao Cripple heard the price offered by the old man Mi to Lin Mu, he immediately fried the pot: "Old man Mi, you are not following the rules." ”

The old man smiled and said: "I don't talk about the rules, who just said that the rules I set don't need to be followed, and I won't abide by the rules you set." ”

Cao Cripple was choked by the old man's words, and he had nothing to say, so he could only continue to exert himself on Lin Mu's body: "What kind of conditions the old man Mi gave you, I will give you the same conditions, and they are all double, you can think about it yourself." ”

Although Lin Mu didn't know what the two old urchins were betting. However, no matter what bet they made, Lin Mu would not hand over the Shadowless Sword to the two of them to refine.

The Shadowless Knife is the treasure of his own life, even if the Shadowless Knife wants to advance, Lin Mu will not fake it.

Lin Mu arched his hand and said, "The kindness of the two seniors, the juniors have it, but this spiritual treasure, the juniors have to refine it themselves." ”

Cao Lame pulled Lin Mu behind him and said, "Boy, you don't have to be afraid of offending people, I know that you want to choose me, but I am worried that this old man will retaliate." It's okay, you follow the old man, no one dares to touch half of your hair. ”

Lin Mu listened to Cao Cripple's words, and also wiped his sweat, and said, "Seniors, juniors really don't need the help of the two seniors. ”

The old man looked at Cao Cripple with a smile and said, "The hot face is attached to the cold butt." I haven't heard of people, don't you need your help?"

was ridiculed by the old man, Cao Cripple also felt that the old face was a little unable to get off the stage, glared at the old man, and said: "He doesn't need your help, you don't have to be happy too early, we will make a draw in this game." ”

After speaking, Cao Cripple pulled Lin Mu over and said, "I said that you kid, I want to be the first person in my dignified instrument, and I want to give you a refining tool for free." You're still not happy, are you getting water in your head? ”

Old man Mi interrupted Cao Cripple and said, "Who admits that you are the first person in the capital of the instrument, this title is not self-appointed by you." ”

"I'm willing to call it that, you old horseman!" Cao Cripple replied without showing weakness.

After finishing speaking, Cao Cripple began to count the trees again: "Boy, you only have the cultivation of the eighth layer of silence, what level of spiritual weapons can you refine, I will help you for free, you are not happy to ......"

Lin Mu knew that if he didn't interrupt Cao Cripple, he would keep pestering him, so he hurriedly got rid of it and then arched his hand: "The two seniors are polite, the juniors are going to go in first, and the 100,000 top-grade spirit stones on this day are not a small amount for the juniors." ”

After speaking, Lin Mu no longer gave the two of them a chance to talk, and directly entered the independent space that belonged to him.

Cao Cripple saw that Lin Mu was hiding from himself like a plague god, and he also said angrily: "Today, the old man wants to see what level of spiritual treasure you can refine from this uninteresting boy." ”

Old man Mi said: "If other people's families don't use you, you will hold a grudge, and with a mind like you, you will never want to be the first person in the capital." ”

Cao Cripple looked at the old man Mi and said, "I can't become the first person, and I'm stronger than you, the third." ”

Entering the formation, Lin Mu also got rid of the entanglement between the two, and he couldn't help but breathe a sigh of relief.

After calming down for a while, Lin Mu had a chance to observe the treasure of this refining weapon.

The aura and treasure here are definitely much thicker than outside. The success rate of refining here will definitely be greatly improved, and at the same time, the quality of the spirit treasure will also be greatly increased.

In the center of the space, a shaft was dug out, and the raging geocentric fire gushed out from inside, making the temperature here at least dozens of degrees higher than outside.

However, the Earth's Core Fire is useless to Lin Mu, and upgrading the Shadowless Knife, Lin Mu will never use this kind of low-level flame.

Kneeling on the ground, the forest wood adjusted for a long time. It's also hands-on preparation, and it's time to start upgrading the Shadowless Knife.

Lin Mu took out the shadowless knife first, and his fingers tapped lightly on the back of the knife, and a crisp sound came out, which sounded very pleasant.

Although the Shadowless Knife was the last treasure that Lin Mu obtained in the fairy world, it was also the most precious treasure.

This kind of treasure that can be upgraded, not to mention the cultivation realm, is probably unique in the immortal realm.

Lin Mu placed the Shadowless Knife into the Sky Fire, allowing the Sky Fire to melt the Shadowless Knife.

In three days, the Shadowless Knife completely melted into the heavenly fire, but what surprised Lin Mu was that. There is no impurity in the Shadowless Knife, which shows that the Shadowless Knife is extraordinary.

After the Shadowless Knife melted, Lin Mu took out the divine iron given to him by the mermaid ancestor, cut a piece from it, and threw it into the heavenly fire.

Shentetsu is also very resistant to burning, and it also took three days to melt it. And what surprised Lin Mu again was that Shentie didn't even have half a point of impurities.

The fewer impurities in the material, the higher the grade of the material.

Completely free of impurities like the Shadowless Knife and the Divine Iron, this is definitely the only one in Lin Mu's life. As for what level of material it is, Lin Mu can't give an explanation. It can only be said that these two things are the top materials among the top.

Then Lin Mu put all kinds of materials he collected and auctioned into the sky fire.

Although these materials are also top-level materials, they have a lot of impurities, which shows that the gap between them and the Divine Iron and the Shadowless Knife is not a star and a half.

After all the impurities have been evaporated, the most important step of the forest tree is also started.

Although Lin Mu was not a refiner, with his knowledge as an immortal, refining a spirit treasure was not a problem at all.

What's more, when Lin Mu was in Xijizhou before, he also got the experience and fire control skills of an ancient refining master, and refining spiritual weapons was not a problem.

After melting, the Shadowless Knife, which is a mixture of divine iron and various top-quality materials, constantly changes various shapes in the air.

However, this is not Lin Mu, who is testing the best attack form of the Shadowless Knife, but Lin Mu suddenly finds that he can't make the Shadowless Knife form again.

This is not a good thing, the Shadowless Knife cannot be formed, that means that the Shadowless Knife, if it does not have any attack power, the Shadowless Knife will be useless.

Such a situation was completely unforeseen by Lin Mu before he started.

"Channel the treasure of this place into the Shadowless Knife. After the fusion of the Shadowless Sword and the Divine Iron, it was sublimated again. Although he still hasn't been able to generate a soul of weapons, he already has the potential to become a top-level magic weapon, and he must be shaped with a spiritual treasure!"

After listening to the analysis of the Guangdao people, Lin Mu no longer hesitated, and directly attracted the treasure qi of the Quartet and entered the melted shadowless knife.

Sure enough, the treasure qi entered the Shadowless Knife, and the shape of the Shadowless Knife immediately stabilized, and it had a tendency to gradually solidify.

However, Lin Mu soon discovered another problem, that is, the Shadowless Knife, the demand for treasure was too great.

The treasure qi in his area only lasted for less than half an hour, and it was completely drained by the Shadowless Knife, and the Shadowless Knife, which had emptied the treasure, began to extract the treasure qi from the outside world and continued to enter the space where the forest was located.

"Hmm!"

Cao Cripple and Mi Old Man, who had been guarding outside, had already noticed it the moment the treasure flowed.

The two of them looked at the area where Lin Mu entered, and their brows couldn't help frowning slightly.

"What kind of spiritual treasure is he refining, and he needs so many treasures. The old man looked at the area where the forest was located with deep eyes.

Cao Cripple also looked intently at the area where Lin Mu was located, and said, "No matter what kind of spirit treasure he refines, it must be extraordinary. It seems that the two of us have just looked away, and he is not a rookie in refining. ”

Old man Mi surprisingly did not refute Cao Cripple this time, and nodded along with him.

More and more treasures gathered, and soon the space where the forest trees were located was already filled with treasures.

A huge vortex of treasure qi appeared on top of the Shadowless Blade. The Shadowless Blade absorbed endless treasures while raising its own grade.

From the first-grade spirit treasure, it soared all the way, and soon reached the six-grade spirit treasure. However, at this time, the Shadowless Knife was only half condensed.
