In Chen Zhiyuan's refining room, the apprentices had the most difficult day, and they were exhausted when they left the refining room at night, both physically and mentally.

The most tired were the two first-grade refiners, because they were the only two people who could successfully engrave, so the pressure was all on them, and in the end, they lived up to expectations and successfully carved the inscription.

However, when everyone dragged their tired bodies out of the refining room, they all silently made a decision in their hearts, as long as it wasn't He Yuan to talk about it in the future, they wouldn't come again.

Ouyang Yushui finally agreed to Chen Zhiyuan's proposal, after all, after consideration, he found that this could indeed effectively reduce the pressure on the refiner, and also enrich the apprentice's knowledge, killing two birds with one stone.

In the past few days, Ouyang Yushui's arrangement has also come out, the East Refining Hall is a pilot refining hall for opening a lecture hall, opening two sessions a month, each session is open for three days, and you can sign up if you want to come, and the cost of listening to the lecture is one gold per apprentice, and the refiner is free.

Chen Zhiyuan, the initiator, was retaliated against by Ouyang Yushui, and in the first three months of the arrangement, Chen Zhiyuan alone accounted for half of it, and He Yuan, as a first-grade refiner, also made an exception to give a lecture, and the remaining two times were presided over by Ouyang Yushui and another refiner.

"It's not fair, Lao Ou, why have I been assigned a lecture every month for three months?"

"Well, isn't that what you asked? I thought you had made this proposal, and you were very well prepared, and I would have liked to arrange it for you for half a year first. ”

Ouyang Yushui sat on the chair, smoking a cigarette, while looking at Chen Zhiyuan with drooping eyelids, and added another sentence after speaking:

"Also, don't call me Lao Ou, call me master!"

"Okay old Ou, I know old Ou. ”

Chen Zhiyuan nodded, just stepped out of Ouyang Yushui's refining room, and immediately retreated.

"Why don't I see the reward?"

"Reward?

"The reward for giving opinions, and the reward for lecturing, the arrangements have come out, why haven't you seen the reward?"

Ouyang Yushui opened his eyes and glanced at Chen Zhiyuan, took a slow and leisurely puff of cigarette, and then spit out a long white mist before he spoke:

"Didn't you volunteer to give a lecture? Lao Zhang told me that you invited his apprentice to come that day. ”

"Oh, don't, master, how can this be voluntary, I obviously don't want to. ”

Chen Zhiyuan heard that the whole person was not good, how could this be voluntary, a fool can't do it for nothing, not to mention that he is much smarter than a fool, can a fool be a refiner? Obviously, that can't!

"Then you're late, now that the news has been announced, if you want to change, you can only wait for the next round, if you have time to play with me, it's better to go back and prepare early." ”

After speaking, Ouyang Yushui didn't care about Chen Zhiyuan, smoked a cigarette by himself, and walked back to his room slowly.

Seeking a reward failed, and he was made fun of, Chen Zhiyuan gritted his teeth, and his heart was also very angry, okay, if you don't give me a reward, then don't blame me for tossing them at that time.

Hmph, Chen Zhiyuan has already thought about it, isn't it just three times? See if I don't kill you little rabbits.

Chen Zhiyuan, who returned to the refining room, walked into his room like a wind, and did not forget to turn the sign at the door into a state of "retreat", He Yuan looked at Chen Zhiyuan's flashing figure beside him, and scratched his head in confusion.

"Retreat again? Isn't this just coming out? Could it be that Master Ouyang still has any cultivation skills that can make the master immediately break through to the condensation vein?"

If you can't understand something, you should understand it slowly, anyway, if it's true, the master will tell you about it at that time.

"Ding..."

Chen Zhiyuan sat on the stage and gently struck a small bell on the table, and a crisp sound attracted the attention of everyone who was still thinking and discussing.

Don't look at this small bronze bell is inconspicuous, this is a second-grade small bell, engraved with inscriptions such as concentrating and Qingyin, which is a rare auxiliary magic weapon, so it is not Chen Zhiyuan's, but temporarily borrowed from Ouyang Yushui.

Okay, now that we've talked about the double engraving of "sturdy", let's expand on that a bit. ”

According to Jiang Yuan's predecessors' "Multiple Inscriptions", we can know that by finding gaps in the material, the same inscription can be engraved multiple times at different levels in the same position, which can not only save a certain number of inscription bits, but also strengthen the inscriptions already engraved in this position. ”

"Next, we will engrave the hundred-forged steel made of dark iron in the same position many times, which is also the reason why the refining furnace is more difficult to refine than equipment of the same level. ”

After speaking, Chen Zhiyuan took out the hundred forging steel that had been prepared long ago, and each piece was three fingers thick.

The condensed divine consciousness covered the hundred forging steel, so that Chen Zhiyuan could clearly feel every trace of the hundred forging steel, whether it was internal or external.

A wisp of dark red flame appeared on the fingertips, and the flame condensed into a silk thread along Chen Zhiyuan's guidance, like a flexible loach, using 100 forged steel as muddy water, and flexibly shuttling on 100 forged steel.

The surroundings were already silent, and the onlookers held their breath, for fear of disturbing Chen Zhiyuan.

The sweat of the bean slid down Chen Zhiyuan's cheeks, but Chen Zhiyuan devoted himself to the compilation of the inscription, although it was the simplest "solid", but the engraving method was different, and the difficulty was no longer a grade at all.

The speed changed from fast to slow, and then to the back, and Chen Zhiyuan spent a long time almost every inch of his fingertips walking.

One pillar of incense has passed, two pillars of incense have passed, half an hour has passed, and an hour has passed.

Finally, when Chen Zhiyuan felt that his spiritual power was already difficult to support, and his divine sense was about to be exhausted, his fingertips drew the last stroke, and with a "clank", the hundred forging steel fell on the table.

"As you can see, this is my current limit, thirteen layers, although it has not reached the realm of one inscription per layer described in the Multiple Inscriptions, but it is enough as a material for the refining furnace. ”

"Thirteen floors! Oh my God, thirteen floors!"

"How many inscriptions is thirteen floors?"

"Six Dao, one inscription bit, up to six inscription bits!"

"The first-grade refining furnace only needs six or thirteen layers, and it is estimated that it has reached the standard of the second-grade refining furnace!"

"Impossible, the second-grade refining furnace must be second-grade materials, otherwise even if the furnace is completed, the quality cannot be guaranteed. ”

After Chen Zhiyuan finished, he retreated to the side to rest first, and continued to concentrate for an hour, Chen Zhiyuan was also a little unbearable, the front was quite easy, starting from the fourth layer, the difficulty of each layer was doubled, and by the time he reached the thirteenth layer, Chen Zhiyuan was already unable to move an inch.

The apprentices below were still chattering and discussing, and the refiners who had come to listen had already started studying Chen Zhiyuan's freshly refined hundred-forged steel.

"The thirteenth floor is indeed rare, how many people in the East Refining Hall can reach the thirteenth floor at present?"

"Master Ouyang should be able to, others, can Lao Zhangtou do it?"

"No, no, I might have thought about trying it when I was younger, but not now. ”

As soon as Lao Zhang heard about himself, he immediately shook his head and denied it, it is true that his cultivation is higher than Chen Zhiyuan, and his refining experience is also richer than Chen Zhiyuan, but this kind of technical matter, you still have to use strength to speak, refining weapons will not deceive people, if it doesn't work, it won't work.

"Ah, doesn't this mean that Xiao Yuan is the only one in our East Refining Instrument Hall?"

"Then sure, in exchange for you, can you?"

"I'm sure I can't, I'll have to use the steel stacking method to replace me. ”

"Stacked steel, he has to stack more than twenty or thirty layers. ”

"It's the divine sense, and he's trained the divine sense. ”

While the many refiners were still discussing, Ouyang Yushui didn't know when he had already walked behind them, and he broke the key to it with one word.

"He still has time to exercise his senses?"

Lao Zhang just opened his mouth to ask, and suddenly remembered that Chen Zhiyuan had just exchanged some pills from him not long ago, which happened to be related to divine consciousness, so he closed his mouth.

How others cultivate, and what they cultivate, is their own business, and they don't have much right to interfere.

It seems that this kid usually hides a hand, and he is reluctant to show his strength if he doesn't force it.

Ouyang Yushui thought about it while touching the beard on his chin, feeling that he still had to find something to do for Chen Zhiyuan in the future, otherwise he would be wasted if he was idle.

"Okay, don't gather around here, you have this mood to feel how powerful others are, it's better to work hard yourself, I will cancel his lecture arrangement next month, replace it with you, I hope you don't let me down." ”

After speaking, Ouyang Yushui walked up to the stage, picked up the piece of forged steel engraved by Chen Zhiyuan in his hand, broke off a piece of it vigorously, kept playing with it in his hand, and slowly left.

"It's time for Yuan Zhicheng to learn the formation, and he has basically mastered the inscription. ”

The cyan flame on his hand lit up, but it was only restrained in the palm of Ouyang Yushui's hand, and the temperature did not leak out at all.

The broken piece of 100 forged steel melted in Ouyang Yushui's hands at a speed visible to the naked eye, and then in the wrap of the flames, as if a pair of dexterous hands had kneaded it again, and a piece of 100 forged steel that was exactly the same as Chen Zhiyuan's previous one appeared in Ouyang Yushui's hand, but it was a miniature version.

Lines slowly appeared on the miniature version of the 100-forged steel sheet, which was still recognizable at first, which was an inscription similar to "solid", but gradually the whole line was covered with small steel sheets, until it was completely unrecognizable.

At this time, the flame in Ouyang Yushui's hand was withdrawn, the steel sheet slowly cooled down, and Ouyang Yushui broke it with his hands again, this time it could only be bent, not broken as before.

"The way of refining weapons is still far away. ”

After saying a word to himself, Ouyang Yushui casually threw the piece of steel in his hand to the side of the road.

Not long after Ouyang Yushui left, Chen Zhiyuan adjusted, sat down on the stage again with a devilish smile, and scared everyone in the audience when he opened his mouth.

"Then the next two days, is everyone's practice time, my requirements are not high, each person will receive ten kilograms of black iron ingots for free, the apprentice can stack four layers in two days, I will give two hundred catties of black iron for nothing, and those who fail will spend money to buy these ten kilograms, is there anyone who accepts the challenge?"

"What about the alchemist?"

"The refiner adds three layers for every product of the refiner, and you are all a refiner, do you lack this bit of dark iron?"

"Hehe, it's not itchy. ”

"Well, that's you. ”

Chen Zhiyuan's move unknowingly opened a refining boom in the East Refining Hall, of course, there are also reasons behind Ouyang Yushui's promotion.

When Ouyang Yushui came back, he made an outline and assigned a task to each refiner, and everyone had to work hard in one direction, and then share their progress.

And these three months were the fastest period for the apprentices of the East Refining Hall, and it was also a period when all kinds of new equipment and new skills were emerging one after another, and this feast naturally attracted the attention of other refining halls.

"At the beginning of next month, a refining competition will be held in the square in front of the City Lord's Mansion?"

He Yuan looked at the news in his hand, his brows couldn't help frowning, and he turned back to ask Chen Zhiyuan:

"Master, do you want to participate?"

"Participate, why don't you participate? The first prize for the second-grade refiner is five medium-grade spirit stones. ”
