Su Dong was completely speechless, he tried no less than a hundred methods, but he was still unable to smelt this piece of pig iron, whether it was a high-temperature furnace or a neutralizer test, there was no way to change the shape of this piece of pig iron.

In the past few days, Su Dong's face has become more and more ugly, and he is frantically looking for any possible solution to the problem in the Divine Pavilion.

Pig iron that can't be smelted, no matter how good the quality is, is just a piece of iron, it's like Su Dong holding a treasure in his hand, but he doesn't know how to use it, how can he not be impatient?

There was more Lei Tian in the short party every night, and he was very excited to join Su Dong's small group, after all, Su Dong and Zuo Fang's strength was there, both of them were no less than the existence of the first combat power Tallinn, and Su Dong and Zuo Fang were not proud at all, they were easy to get along with.

Lei Tian is a weirdo in the Lingwu Department, he usually raises insects for a living, and those ugly reptiles are very unpopular, so everyone avoids him, afraid that a few insects will accidentally crawl out of Lei Tian's body and run to himself.

But Su Dong's small group didn't mind Lei Tian at all, the piano sound was a little pepper, and her mouth was very vicious, whoever saw her had to walk around, Zuo Fang had no heart and lungs, a while ago there was a girl who liked him and quietly followed him, but Zuo Fang thought it was hostile and beat up the girl, which became a big joke in the academy.

There is also Huang Buren, who doesn't know martial arts at all and doesn't have any spiritual power, he was born as a businessman, and he is as timid as a mouse, but he is still accepted by Su Dong, and Lei Tian will not have any problems.

It seems that Su Dong has a kind of inclusiveness, all kinds of freaks can live comfortably around him, and he will not be looked at differently.

Unexpectedly, the flower reflects the moon. It's a pretty girl, and she actually likes to fiddle with Lei Tian's insects. You must know that those black reptiles Su Dong felt terrible, but Hua Yingyue teased them in her hands with great interest. This is probably due to the inheritance of the Hua Lao Hei gene.

......

At night, the spiritual lantern is on, and it is the time when the Divine Pavilion should close its doors.

Su Dong sighed, closed the book, and put it on the bookshelf according to the serial number, and after doing this, he sent back the books scattered elsewhere as usual.

It was Shui Mo who was in charge of taking care of the Divine Pavilion, and it seemed that he was related to Shui Daozi, but Su Dong didn't ask much. In his mode of thinking, ink is ink and water, and Shuidaozi is Shuidaozi, which are fundamentally two different things, and he will not be angry with the old man of ink because Shuidaozi has a bad relationship with himself.

With Su Dong's help, the work of ink painting was much easier, and he made a cup of tea in the yard and watched Su Dong finish sorting out the books.

"Master Shui, I'll go back if there's nothing to do. Come back the day after tomorrow. Su Dong said lightly.

Shui Mo pointed to the teapot and cup in front of him, and said with a smile: "Try this, the hundred bitter flowers just sent." ”

Su Dong was also a little interested in the tea ceremony, so he sat down and poured himself a drink. Putting down the cup, Su Dong recalled the taste of this tea.

"How's the tea?" asked Shui Mo.

Su Dong said: "First sweet and then bitter, bitter and then fragrant." This hundred bitter flower tea is really interesting. ”

Shui Mo nodded: "The tip of the tongue is responsible for sensing sweetness, and if you take a small sip and drink it slowly, you will feel an extremely sweet taste." This taste will cover the bitterness that follows, as if you take a sip of the cup. Then you will be tortured to death. ”

Su Dong said with a smile: "Drinking tea is actually an artistic conception, it is better to drink cold white water to quench your thirst, fortunately, I still know something, and I didn't waste your old good tea in vain." ”

Shui Mo smiled and said: "Recently, seeing your gloomy face, there must be a problem that cannot be solved, so please have a cup of tea, which can be regarded as a thank you for your hard work in helping me tidy up the academy these days." ”

Su Dong said: "I can't work hard, I think you always want to remind me of the truth that if you want to hurry, you can't reach it, you have to drink tea slowly, and you have to master the technique slowly, it's useless to be anxious." ”

Shui Mo said with satisfaction: "It does mean this, I see that you have been reading the books that have been specially picked up and smelted in the past two days, and within two days, you have read one hundred and thirteen books, so you must have encountered a problem with raw materials, right?"

Su Dong was stunned, Ink even remembered how many books he read every day? It seems that this bad old man has a pretty good memory.

Nodding, Su Dong said: "Your old memory is really amazing, I did encounter a problem this time, so that I can't eat and sleep unstable, Master Yisuo gave me a piece of pig iron with a strange texture, high hardness, light weight, is the best raw material for building spirit armor, but unfortunately, I can't smelt it with such a good raw material, I can only stare at it every day." ”

Ink said: "I know the piece of pig iron you said, Wudao has tried to smelt it over the years, but unfortunately none of them succeeded, that piece of pig iron has a suspicious origin, it is one of the ancient monsters brought by the creation god Pingtian, presumably Yisuo wants to test you." ”

Su Dong stuck out his tongue and said: "Test? I think he wants to trap me, I have a problem, if something can't be solved, I can't eat well, I can't sleep, my head has grown since I got this thing." ”

Shui Mo smiled: "I'm not a foundry, this kind of thing can't help you, but I remember that there are book catalogs that those guys who studied casting used to read, and I can tell you if you want it." ”

"The previous catalog!?" Su Dong was taken aback and said, "I'm afraid it was all hundreds of thousands of years ago, right?"

Shui Mo said disapprerovingly: "I work in the Divine Pavilion, just because I have the ability to never forget, everything that I look at, I will still remember it clearly after many years." ”

"Master Shui, you are god!" Su Dong said with a thumbs up at the ink, Su Dong will never be stingy with such a flattering thing as sycophancy.

"It's just that my memory is better, it's not magical, or I'll write you a table of contents now?" "Ink Road.

Su Dong nodded heavily and said, "Okay, of course." ”

Soon, Shui Mo took a pen and paper and wrote a long list of numbers on the paper, and said as he wrote: "When they tried to smelt this piece of pig iron, they all consulted these books, and the number behind them is the number of times they have consulted, and the most one is the advanced theory of metal qualitative, which has been consulted thousands of times." ”

Su Dong was naturally surprised, and Ink still remembered which books had been consulted. And the number of times you check it, this kind of memory can be called a god!

Take the book list. Su Dong carefully held it in his arms and said, "Okay." I'll be here the morning after tomorrow, but I'm not going to look at the books, I'm going to see what none of them have read. ”

Shui Mo frowned, and said inexplicably: "They have all found clues in these books, why don't you read them? Could it be that I am blinding you?"

Su Dong hurriedly waved his hand and said: "Master Shui, don't get me wrong, I definitely didn't mean that, it's just that so many masters haven't found a solution to the problem from these books, probably because the solution is not here at all." What I want to read is a book that no one else has read, and what I want to try is what others have not tried. ”

Shui Mo was stunned suddenly, and his gaze at Su Dong was a little surprised.

Soon, Shui Mo came back and said, "Reject the influence of others and reopen a research route by yourself?" This is a very good idea, so let's stay here tonight and read, I want to know. This piece of pig iron, which has plagued the casting system for many years, can it be solved in your hands? ”

......

The old man in ink opened the back door for Su Dong, so that he could read books in the Divine Theory Pavilion at night, of course Su Dong would not refuse this kind of good thing.

Su Dong even personally made a few snacks for the ink. Coaxed him around.

Approaching early in the morning, Ink invited Su Dong out without mercy, and opened his mind for two days. Open the Heavenly Pavilion on a single day, and today is the time for the Heavenly Pavilion to open. When Su Dong left, he met two strangers who entered the academy, and these two people did not seem to belong to Wudao. Su Dong had never seen them either.

Su Dong didn't expect it, but it didn't matter, Ink gave himself one more night of study time, which already made Su Dong very content.

Time flies quickly, Su Dong is now practicing and studying day by day, the pace of life is faster than in the past, it is good to be able to sleep for two hours a day, and even the routine party every night, Su Dong began to be absent often.

Hua Yingyue knew that Su Dong was busy and didn't care, but Qin Yin didn't say anything bad about Su Dong, and felt that Su Dong didn't care enough about Hua Yingyue.

The strange black wood fern in the spiritual field is also going to be seen, but unfortunately this thing is completely incomprehensible, and I know that it grows vigorously, does not bloom, and does not bear fruit, so maybe it will grow to the sky one day.

Su Dong's black wood fern has become a big landscape in the academy, this thing is arrogant, it was originally just killing the spirit valley and elixir that Su Dong planted next to him, as this product became taller and taller, the two spiritual fields around him also died, Su Dong muttered in his heart, but no one told him.

Su Dong now specially selects books that other foundries don't read to study, and as his research deepens, his understanding of materials has embarked on a very different path from other foundries.

Su Dong found out from the information that smelting metals not only have fire casting, neutralization, and forging, but also some very rare ways, such as spirit quenching.

The art of spiritual quenching is quite unpopular, and so far I have not heard of anyone who has ever succeeded, and the process is extremely complicated.

As we all know, metals are composed of many fine particles, and the art of spiritual quenching uses spiritual power to decompose a piece of metal into fine particles, and then remove the impurities in it and recombine them.

This is really a whimsical technology, and probably only a freak like Su Dong with a strange mind would study such a cold and complicated thing.

"According to your explanation, isn't it a combination of smelting, shaping, and casting? It needs to be completed in one go! Can such a complex process be successful?" Su Dong said his thoughts to Phantom Rain, and immediately made Phantom Rain shake his head.

Su Dong said: "It's hard to say, you need to test it first, and figure out how to use spiritual power to break down a piece of metal." ”

"What are you going to do?" asked Phantom Rain.

Su Dong said: "Using the metal gathering effect of the ice casting rooftop, I forcibly injected spiritual power into it, and then I manipulated the spiritual power to operate, generating heat and centrifugal force to disperse the metal. ”

Phantom Rain was stunned for a moment, and said in a loud voice: "Use centrifugal force to decompose metal!? You are simply nonsense! You can do this if you want to, but you are not allowed to use ice to cast the roof! This is a treasure left by Lord Ice God, what if it is broken?"

Su Dong thought about it for a while and felt that it was not cost-effective to break his baby, anyway, the casting department has a free casting table, so don't use it in vain, just go there and do experiments. (To be continued.) )
