"Can you have pen and ink?" Liang Tian was already in his chest, put the spear back in the brocade box, and looked at the steward.

The thin man was quite surprised, but he didn't ask much, and led the group to the counter, where the four treasures of the study had already been prepared.

Liang Tian grabbed a brush casually, carried the pen like flying, and wrote a large piece of paper in one go.

"Alright, let's show it to the Iron Master."

The steward did not spy on his Chinese characters, and was a little worried when he heard this: "There is still plenty of time, adults may wish to consider one or two more?" ”

Liang Tian waved his hand and responded, "No need, sir, just help me transfer it with peace of mind." ”

The steward did not persuade again, but stepped forward to take the paper, rolled it into a cylinder, and walked into the inner courtyard.

Here, it is not as hot and open as outside, but it is a little quiet. In the middle of the courtyard was a huge furnace with flames growing inside, and around it, casting tables and molds of various weapons were readily scattered around.

There was a pool not far away, and the biting chill was felt from afar, and at this time, an old man with half-white hair and a still strong physique was standing next to the pool.

In front of him there was a red-hot blade, no handle, suspended in the void, with the old man's palm slightly moved, the blade submerged into the cold pool, sneered loudly, the water surface quickly rose a large thick fog, the old man was not moved at all, his eyes were staring at the cold pool, suddenly, the palm of his hand turned over, the blade rushed out of the water, into the furnace, the flame in the furnace suddenly weakened a little, gently licked the blade of the knife.

Only then did the steward greet him and present the paper: "Boss, this is the answer from the little boy just now." ”

"Oh? is so fast, is it because he wants to fool the old man and want to get by? The Iron Master didn't pick it up, and his tone was already quite impatient.

"Owner, you also know about this year's event in our Black Rock City, I think those three people are extraordinary, I am afraid that they are the disciples of the three sects, and those who can come here are some capable. If you don't like it, and after reading their answers, pick some mistakes and omissions and send them away, it's not good to provoke these big people for no reason. ”

As if moved by the steward's thoughtfulness and earnest words, Master Tie took the paper and glanced at it casually:

"The goodness of this gun is only in the material, and everything else, there are too many mistakes and omissions, and there are too many words to say."

After only looking at the first line, Master Tie's face changed, and he scolded: "The concubine is arrogant! ”

When I was angry, I immediately browsed faster, and made up my mind that if I couldn't tell one, two, three, I would definitely teach this crazy future life a good lesson.

"The head of the gun is the soul of the gun, and it is also the core of what makes the gun different from the stick. Therefore, there are thousands of marksmanship, after all, you can't escape a stabbing word, and the limit of a gun is often determined by the head of the gun. ”

For this reason, although the moire iron casting head was specially selected, so that its hardness is far greater than that of ordinary gold and iron, there are still four errors and omissions. First, the method of smelting is clumsy, the hammer forging force is insufficient, and the impurities in the moire iron ore have not been completely removed; Second, the polishing is rough, if you deal with the demon clan, even if you can break through the defense, it is also very easy to get out; Third, when quenching and annealing, the grasp of the state of the gun head cannot be perfect. ”

"The above three points, perhaps because the grade of the moire iron itself is too high, the caster's cultivation is limited, and it is understandable that he cannot achieve perfect control, but this last point is the caster's ability is insufficient, I know a way, which can increase the hardness of the gun head by at least three percent."

"When you run out of paper, let's write so much."

Master Tie's face gradually calmed down from his anger, these problems were pointed out, but he couldn't be wrong, in some places, he himself felt that he could be more perfect, but he couldn't do it. But this tone is really annoying, and when I took out a quite complacent work, I was taught that I didn't do it well enough, and it was hard for anyone to resist it. In addition, he was also interested in the methods described on paper to make the tip harder.

"Call them in." The Iron Master waved as he spoke, and the long knife in the furnace flew out and stuck aside, which was already completed.

The steward was stunned, he just saw the owner jumping like thunder, and he couldn't wait to rush out and cut that kid a few times, why did he change his attitude after a while, could that little boy really point out the owner's mistakes? With doubts, the housekeeper beckoned Liang Tian and the others in.

Liang Tian looked at the environment in the courtyard and nodded secretly, there is nothing missing, this is easy to do.

"It's you, asking for a mid-grade source gun?" Master Tie's expression was serious, and his tone was rather unkind.

"Yes, the master is still satisfied with the boy's evaluation?" Liang Tian was not afraid, and even pointed to the paper in the old man's hand, his tone was a little provocative, and he thought to himself, I have wronged you, Master Tie.

The Iron Master snorted coldly: "You are convincing, I wonder if you can verify what you said?" ”

"Want to make a bet?" Liang Tian smiled ill-intentionedly.

"Tell me about it." Master Tie replied, I want to see what kind of medicine is sold in this kid's gourd.

"If I can verify it, how about you give me some moire iron?"

"Dare you to come for the moire iron?" The Iron Master sneered, this moire iron was extremely precious, and he would only use it when he was at his best.

Liang Tian saw that the old man was a little reluctant, and continued: "The Zhongpin Source Gun is for my brother, and the moire iron is for myself, and I won't hide it from you." What is said on the paper is all true, you are really wasting this way with this moire iron, if you get my method, you will save much more moire iron in the future than you give me today. You don't lose money left and right, why don't you dare to bet with me? ”

The Iron Master pondered for a moment, feeling that although this kid was not pleasant, his words were also sincere, if he really got the new casting method, he would indeed earn it himself, but he couldn't agree to him so easily.

"If you succeed, I have nothing to say; But if you fail, aren't you delaying me for so much? ”

Liang Tian immediately understood what Master Tie meant, and he was not angry: "Then let's do it, you give me the materials, and I will use this method to cast a sword in your small courtyard, and I will take the sword away, and I will not ask for a penny, and teach this method to you; If you fail, I will not only compensate you for the consumption of all materials, but also give you an additional demon core of the Great Demon Realm, and I will not take the sword away, you can melt and reforge it again, and make a lot of money in vain. How is it? ”

The Iron Master thought for a moment, but didn't notice anything suspicious, and then nodded: "Yes." ”

"In this case, please also ask the Iron Master to take out all the ores for me to use." Liang Tian smiled slightly.

"You didn't say you wanted to take all my ore?" The Iron Master blew his beard and glared.

"Master, do you only use one material for casting? Don't worry, I just want to pick a match, I won't squander it, and if you can't stand it, you can stop me at any time. Liang Tian glanced at the old man, with a hint of contempt.

Master Tie was really excited, thinking that his cultivation in the Four Clouds Realm was still afraid that he would not be able to control a junior in the Qi Realm, wasn't he laughed at in vain?

So he swiped through the ring, and suddenly several piles of ore appeared in the courtyard.

"Moire iron."

"Flowing Sands."

"Dark Pulp."

"Xinghai Stone."

……

They are all of the highest grades, and there are countless ordinary copper, iron, gold and silver, etc., and the iron master bluntly said that he can take it and take it out, and if he has enough, he will not take it out.

Liang Tian nodded with satisfaction, and ran the Heavenly Machine Technique to check the quality of various ores.

In the end, he took two kinds of moire iron and Xinghai stone, and said to the iron master: "Master, I will use these two." ”

With a wave of his hand, the Iron Master put away the other ores, and then snorted coldly: "You can pick, this Xinghai Stone is taken from the Heavenly Fire, the color is magnificent but the hardness is extremely high, and it can barely be regarded as a seven-grade ore." ”

Liang Tian smiled slightly, did not answer, but began to move in his hand. His right hand swept across the void, and a series of supernatural runes emerged, streaked across a graceful trajectory, and condensed into a formation.

The formation "Quenching", Liuhe level, is a formation derived from the addition of a "frost" rune on the basis of the "Smelting Array", which controls fire and cold, and integrates into one.

"It's a formation master!" The Iron Master couldn't help but exclaim.

Liang Tian had no time to pay attention, his heart moved, orange-red flames bloomed in front of him, and with a wave of his hand, a cloud of moire iron and a small ball of Xinghai Stone flew into the formation at the same time, and the fire suddenly became fierce.

The flames driven by the "Smelting Array" can be easily refined even by the demon core of the Great Demon Realm, and the same seven-grade cloud pattern iron and Xinghai stone are of course no problem.

In the middle of the large array, a ball of blue liquid and a ball of "white clouds" floated in mid-air.

Liang Tian's mental power probed out, gradually approaching the two masses of liquid, the Heavenly Machine Technique continued to operate, the whole process was smooth and natural, the color of the water mass changed from blue and white mixed, and gradually changed to a regular arrangement of blue and white, exuding a dazzling brilliance, as if it had become a whole.

The Iron Master couldn't help but say on the side: "It's amazing!" How can a mixture of two ores have such a perfect form? ”

It's not that he hasn't heard of the mixing of two ores, and even he himself has mixed the two materials, but it is through a high-grade material, forcibly raising the overall quality, and often the final weapon is far inferior to the high-grade material itself in hardness and stability, and there has never been such a perfect color in the smelting step.

The Iron Master has begun to wonder what kind of hardness and stability this blue-white liquid can finally achieve, and will a miracle happen?

With a wave of his right hand, Liang Tian rolled up a sword-shaped mold on the ground, and his mind drew out a blue-white liquid, poured it into the mold, and sealed it.

Leaving the high-temperature environment, the blue-white liquid resolidified into an iron block at an extremely fast speed, and Liang Tian's mind had been probing every change in it.

When the perfect state of the Heavenly Machine Technique is reached, the source qi is pushed out, the mold is opened, and the sword embryo is sent to the casting table, and then the casting hammer is rolled up, wrapped up and down, and smashed down on the sword embryo.
