On Wednesday, Ling Shijian still didn't go out.

So far, she hasn't gone out for four days, she hasn't gone out for activities, she hasn't gone out to buy groceries, and she hasn't gone out to eat.

Fortunately, she is indeed an immortal cultivator, not to mention not eating or drinking for four days, even if she doesn't eat or drink from now on, it is not a big problem.

Obviously she didn't need to eat, so why did she eat before?

There are several reasons for this: one is greedy; One is mood problems, maintaining the living habits of ordinary people is conducive to peace of mind; One is to help with cultivation, because the power of qi and blood can be converted into mana, and the growth of mana is both cultivation.

Of course, more often than not, the Immortal Cultivation Sect does not recommend eating whole grains and human food.

This is to ensure that the practitioner's six roots are pure and the Dao body pure. After the foundation is successfully built and the Dao body is condensed, ordinary immortal cultivators will carry out the valley reclamation, just to eliminate the vulgarity of the grains accumulated in the body.

And once they enter the realm of self-cultivation, immortal cultivators will no longer consume grains, so as not to pollute their pure and unsullied Dao body with mortal things.

In fact, there is a similar statement in the human science community. That is, the ultimate life expectancy of the human body is about 180 years old, but basically no one can live to the age of 180, the reason is that in the process of ingesting food, people will inevitably ingest pollutants and poisons, which harm the human body and make people live the ultimate lifespan.

If someone can do it without eating, drinking, breathing, and still not dying, then he will live to be about 180 years old.

This is also the reason why the ultimate lifespan of the Self-cultivation Realm is one hundred and eighty years old. The self-cultivation realm is self-cultivation, and there is no higher than the human body, so its ultimate life span is the ultimate life span of the mortal body.

It seems that the benefits of not eating are greater than eating, so why does Ling Shijian, who is a famous and decent family, have no scruples?

！！

Jokes, everyone has seen their state of mind, where is they still shackled by the flesh?

In addition, with her talent, from the very beginning of cultivating immortals, her goal was not to cultivate the body or the qi realm.

Could it be that seeing the state of mind is her destination? Apparently not.

And if you want to ask Zhang Ziyu, why does this garbage have no scruples?

…… Because he doesn't know the importance of eating and not eating, it doesn't matter if he sees the Lingshi Sword, he doesn't care.

Get up, wash, go out, before going to work, Zhang Ziyu went to the door to take a look again, and saw Ling Shijian huddled in the sofa, holding his mobile phone and playing games, still there, not dead, and then there was no reaction to his behavior of entering the house.

He closed the door with peace of mind, went downstairs, had breakfast, and drove to work.

This batch of steel coils was rolled in the hot rolling workshop yesterday, and he worked overtime to finish rolling, so after arriving at the company today, he found someone to transport the steel coils to the cold rolling workshop with a forklift in the morning. Ready for cold rolling.

It's just a little unfortunate that the cold rolling workshop has other rolling tasks all day today, and it can't be rolled.

He pinched his fingers and calculated, today Wednesday, August 13, tomorrow 14, Friday is the Mid-Autumn Festival, if tomorrow can arrange his rolling shift, then he can finish the cold rolling before the holiday, and then wait for the holiday to come back, can go directly to the finishing workshop.

There is still time.

It's a pity that when he took the process sheet to the cold rolling workshop in the afternoon, he learned that not only today's shift was full, but also the rolling shift tonight, tomorrow, and tomorrow night were full.

When asked about the reason, it was because this year's Mid-Autumn Festival and National Day were next to each other, and there were three days in between.

And if you take an annual leave in the middle three days, you can get the Mid-Autumn Festival + annual leave + National Day super festival gift package, which can rest for half a month in a row, which is a longer holiday than the Spring Festival holiday.

Therefore, many technicians and engineers want to finish the work in hand quickly, and then take the opportunity to take a leave and rest for half a month.

In this half month, whether it is going home or traveling, it is okay.

Some time ago, he was busy dealing with Zheng Yi, and he was waiting for death in fear for the past few days, and Zhang Ziyu didn't react until this time.

Oh, can you take a break for half a month?

He thought of his parents, who had almost died without knowing anything, and felt that he could take this opportunity to go home and be with them.

As for the hand-torn steel project that has been dragged for months...... He felt that since it had been delayed for several months, what about another half a month?

Thinking of this, he directly accepted the process order, turned around and went to Zhang Sai's office.

Although he was very shocked by Zhang Ziyu's operation that he had just taken a week's leave and had to take annual leave, considering that he was behind Lingshi Sword, Zhang Sai still waved his pen and still asked him for leave.

To tell the truth, Zhang Ziyu calculated by himself, from last week to the end of the holiday, he went to work for four days for a whole month, and he was still a little embarrassed.

Then, he asked for leave and went straight back to the finishing office.

In his own place in the office, he closed his eyes, posed his body in a roughly five-hearted position, and entered a state of cultivation.

This guy is embarrassed while practicing with pay.

Others are paid fishing, but he is a paid practice.

He can only earn a little salary by fishing, and he can still get cultivation through cultivation, so he has to earn more than ordinary people.

This whole afternoon, he spent most of his time quietly cultivating, recovering his mana, and by the time he got off work, not only had his mana completely recovered, but he even vaguely improved.

For this, he has some understanding:

It seems that some of the truth is universal. If ordinary people want to have muscles, they need to exercise, destroy muscle fiber tissues through exercise, and then supplement protein and carbohydrates to let muscle cells grow and heal, and grow more and stronger muscle cells.

The same is true for cultivation, if you want more mana, you need to deplete the existing mana, and then accumulate mana through practice, and then you can get more and better mana.

He thought that maybe this would be his main way of doing in the future.

Although it was time to get off work today, Zhang Ziyu did not directly clock out of work, but ran to the cold rolling workshop with a set of tools, found his batch of materials, and cut a section from one of the coils.

The width of this roll was more than two meters, and the thickness was five centimeters, and he cut off a slip ten centimeters long.

It is then divided into twenty-one segments as precisely as possible.

That is, twenty pieces of steel ten centimeters long, ten centimeters wide, and five centimeters thick are cut from it.

He quietly took the twenty-one pieces of steel home.

The raw materials of this batch of steel coils are prepared by him, and the casting process and rolling process are designed by him.

I was eating out again, and after returning home at seven o'clock in the evening, Zhang Ziyu went straight into the study.

He took out the steel blocks of different sizes, and then numbered the twenty steel blocks of similar size, with the same structure, composition, and properties from 1 to 20, and arranged them neatly and sequentially on the desk.

No. 1 he did not move, as a control group;

No. 2 he had accumulated enough aura to squirt at it;

On the 3rd, he took it in his hand, accumulated aura, and soaked it for half an hour;

Soak on the 4th for an hour;

Soak for an hour and a half on No. 5.

There should be more grouping in the immersion experiment, but due to the time relationship, it was already past ten o'clock in the evening, so he no longer soaked the steel block with spiritual energy, but directly took out the alchemy furnace and prepared to use the alchemy furnace to make steel.

This is the focus of this "Linggang" project.

However, when he took out the alchemy furnace and was about to throw the No. 6 steel block into it, he was dumbfounded.

At the bottom of the alchemy furnace, there is a small lump of steel, which is born inside the alchemy furnace.

This is the piece of steel that was refined when he tested the temperature of the alchemy furnace last night. He was so tired that he forgot to pour out the molten steel. So after the molten steel cooled, it was born on the alchemy furnace and fused with the alchemy furnace.

He can of course reheat the furnace so that the steel inside the furnace is remelted, and then pour out the molten steel.

However, it was only then that he thought of a very serious question, that is, what he wanted to use to hold the molten steel in this molten state.

You know, the steel in this state has more than 1,000 degrees.

Do you have a container at home that can withstand such high temperatures?

He looked around, only to feel that the washbasin in the bathroom could fit. Because ceramics can withstand high temperatures, they will not be melted by the molten matter of steel.

But even if you pour the molten steel into the washbasin, how do you get it out of the washbasin when it cools?

And there is another question, if the molten steel is not clean and sticks to the inner wall of the alchemy furnace, what tools will be used to clean it?

He felt that what he thought was still too simple, and he wanted to make steel by immortal law, and he was still a lot worse.

Holding the alchemy furnace in the living room for a while, he finally turned around and went out and opened the door opposite...... There's a big guy next door, so why don't you ask her for help?

In the living room, Ling Shijian was wearing long-sleeved and long-trouser pajamas, with his hair scattered, squatting on the ground, and was teasing Xuexue with a cat teasing stick.

He stood at the door, looked at the girl squatting on the ground and teasing the cat, and asked, "Can you do me a favor?" ”

Ling Shijian turned his head, looked at him, and then at the stove in his hand, but did not speak.

Seeing this, he continued: "This furnace, the temperature can be increased to a very high level, and it can melt steel. I melted a piece of steel in it and couldn't get it out. If I melt the steel now, can you help me get the molten steel out? ”

Ling Shijian frowned and looked at him suspiciously.

He explained: "Idle is idle, I practice and play. ”

Ling Shijian sat cross-legged on the ground and looked at him.

He hurriedly brought the door, walked to Ling Shijian with the stove, squatted down, and said: "This furnace can refine steel, and the temperature inside is at least fifteen hundred degrees, can you?" ”

Ling Shijian glanced at him, and finally said the first sentence in the past few days: "Try it." ”

"Okay." Zhang Ziyu nodded.

After that, he put the stove in the palm of his right hand, and then ran the exercises, transferring the dantian mana out of the meridians, coming out of the palm, and injecting it into the runes at the bottom of the furnace.

In an instant, the runes were activated by mana, lit up, and began to absorb the aura of heaven and earth.

Mana and aura are transformed into heat through runes, heating the steel in the furnace.

Looking at Zhang Ziyu in front of him using mana to activate the alchemy furnace and refine steel, a trace of surprise appeared in Ling Shijian's eyes.

This guy only broke through the internal qi release two days ago, and in the blink of an eye, he will use the alchemy furnace to make steel......

Well, something seems wrong? She felt that she was probably violent, and saw a cultivator Meng Xin using the alchemy furnace to make steel.

Last night, Zhang Ziyu injected mana into the furnace for more than ten minutes, and when he opened the lid, the steel had already melted. But it is not known exactly when the steel was melted.

I can just guess that it doesn't take more than ten minutes for this furnace to melt steel.

So this time, he only injected about ten minutes of aura.

When the time was almost up, he stopped and opened the lid with his left hand.

Suddenly, heat radiated out of the furnace, and when I looked at it from a distance, the inside of the furnace was red, and it was completely liquid steel.

Zhang Ziyu was once again amazed in his heart that this alchemy furnace was worthy of cultivating immortals.

He looked at Ling Shijian and asked, "Is it okay?" ”

Ling Shijian didn't speak, just turned her mana into action, then raised her right hand, put a transparent sword qi glove on her hand, and she directly put her hand into the furnace.

Seeing that Ling Shijian was so reckless, Zhang Ziyu couldn't help but be surprised, but before he could speak, Lingshi Jian squeezed his hand and grabbed a handful of liquid steel from the stove.

"It's hot!" She exclaimed.

He also wore sword qi gloves on his left hand, and then poured the liquid steel in his right hand onto his left hand.

Like a child holding a potato that had just been pulled out of the fire, she kept upside down with her left hand and right hand, trying to cool down.

After pouring it a few times, the temperature of the steel cooled down and turned from liquid to viscous.

Is this the strength of seeing a strong state of mind?

Zhang Ziyu was amazed in his heart, holding more than 1,000 degrees of liquid steel in his hand, he only felt so hot.

Her sword aura is really terrifying!

"Is it okay?" he asked. I poured out everything in the stove. ”

Ling Shijian picked up her hand and asked Zhang Ziyu to pour all the liquid steel in the furnace into her palm.

"You scrape it with your sword qi and scrape everything out of the furnace. Clean the inside of the furnace. Zhang Ziyu said again.

When Ling Shijian heard this, he couldn't help but glance at him, the old lady's sword qi was used to do this kind of thing?

But in the end, she still condensed the fine sword qi and patiently and carefully scraped the inner wall of the furnace clean.

Holding all the liquid steel in his hand, it slowly cooled and solidified, and Ling Shijian took both hands into a ball, and the ball became a small iron ball.

It's the size of a glass bead that's one size bigger.

She played with it in her hand and asked Zhang Ziyu, "Do you want to take the refining weapon?" ”

"I don't have any talent for swordsmanship, and I'm really not good at fighting." Zhang Ziyu replied, he saw that the stove was clean, and took the lid and closed it again, "And I am studying materials, and I happen to be the right professional, so I will give it a try." ”

"Refining ......," Ling Shijian groaned slightly, "It is indeed more suitable for you than sword training." ”

"But......," she added, "is very difficult in refining, it is very complicated, and the water is very deep. Moreover, you must first know the runes to learn the refining weapon, because the magic weapon will be engraved with runes to facilitate the circulation of mana in the magic weapon. There are also materials that are inherently suitable for mana circulation. But runes are also hard. ”

Refining is still an interdisciplinary discipline......

When Zhang Ziyu heard this, he asked with a smile: "What is not difficult?" ”

It is difficult to practice, it is difficult to practice swords, it is difficult to refine weapons, it is difficult to write runes, and it is difficult to form formations...... Life is hard, ah, the adult world, or rather, there are no simple things in this world.

"Yes." Although he is a genius in cultivation, Ling Shijian also recognizes Zhang Ziyu's words.

She nodded, then frowned again, "You want to learn alchemy, but you don't have rune books, you don't have refining books, and you don't even have fire for refining. The refining requires a lot of matching small spells, and it needs a kind of fire. You don't have anything. ”

"It's fine." Zhang Ziyu said, "I'll try." Equivalent...... Research, research? Have a play? ”

"Hmm......" Ling Shijian pondered for a while, and then said, "Although Shushan is mainly a sword cultivator, after all, the sect is big, and there are people who take any path, so they should also have knowledge related to refining." When the limelight is over this time, I'll ask Jinyu to find you some refining-related books. ”

Waiting for the limelight to pass?

Zhang Ziyu keenly caught the key words, he took the alchemy furnace in his hand, looked at the steel ball that had solidified in Ling Shijian's hand, and asked, "Regarding this incident, what is the situation on the other side of the Immortal Cultivation Realm?" ”

Ling Shijian glanced at him and didn't answer. She still didn't want to tell him, so that his suspicious nature would frighten herself.

However, seeing that she didn't answer, coupled with the limelight she said, Zhang Ziyu already vaguely understood that there was an inside story in this matter.

Coupled with her appearance, he knew that there was probably no problem with this time.

So he didn't ask any more, but talked back to the refining tool and asked, "Later, I want to do material research, can you help me?" ”

"It depends." Ling Shijian replied lightly.

"......" Zhang Ziyu nodded, "Okay." ”

But he already knew that as long as he asked, she would definitely not refuse.

The stove had been cleaned up, and the girl in front of her was still angry, so Zhang Ziyu didn't mean to talk much, took the stove and got up, ready to go back to his side to try refining spirit steel.

Then he had just walked to the door when the girl behind him stopped him: "Do you still want this?" ”

He looked back and saw that it was the steel ball, the steel ball that Ling Shijian had pinched out with his hand and had her fingerprints on it.

"Don't. You take it...... If you don't like it, throw it away. He replied.

Ling Shijian nodded, holding the steel ball in his hand. She thought it was quite interesting to the steel ball that she had pinched out by hand.

Zhang Ziyu walked out of the room and was about to close the door, when he suddenly remembered one more thing, probed into the house, and asked, "The day after tomorrow, during the Mid-Autumn Festival, do you want to go back to Qingping?" ”

"Of course!"

"Okay......," Zhang Ziyu said, "I will leave very early, so prepare in advance." ”

With that, he closed the door and went out.

Looking at the closed door, Ling Shijian looked at it for a while, his mouth suddenly pursed, he threw the steel ball in his hand to the door, and scolded in a low voice: "Stinky man!" ”

Xue Xue on the side saw the steel ball thrown away, her body moved, jumped to the door in three or two steps, and stopped the steel ball with her two paws...... The stopping technique made the national football team look embarrassed.

Seeing Xue Xue playing with steel balls, Ling Shi said, "I got a good toy for you......"

Zhang Ziyu walked back to his study, picked up the steel block marked 6, and threw it into the furnace.

He looked at the stove and fell into thought again.

If you want to study immortal cultivation materials, it is far from enough to have an alchemy furnace. Compared with the various instruments used to study materials in the university, he is still far behind.

He doesn't even have some basic tools, such as tools to take out molten liquids, such as containers for liquids, you can't always hold them with your hands, right? For example, tools to put materials into an alchemy furnace; For example, the tools for cleaning the alchemy furnace, and so on.

Then, he was short of measuring tools.

Tools and instruments for measuring performance and observing microstructure.

At this stage, it is possible to prostitute the company for nothing, but that is not a long-term solution.

You still need to have it yourself.

But where do you find these things? He has no way in the world, let alone cultivating the immortal world.

"Alas!"

He sighed, but had to put it down first.

Focusing on the alchemy furnace in front of him again, Zhang Ziyu turned on his mana, heated the furnace with his right hand, melted the steel, estimated the time, and when he felt the steel melt, he stretched out his left hand again, ready to condense the aura and join the furnace.

But as soon as he put his left hand to the leading position of the alchemy furnace body, he was stunned again.

The right hand is injecting mana into the furnace, and the left hand is trying to absorb the aura?

The right side goes out, the left side goes in, and the left and right sides run completely different exercise routes?

He doesn't seem to have that ability.

After a pause, he had to stop the matter of his right hand, anyway, the steel block had already melted, so that the left side of the operation method absorbed the aura.

Waiting for the aura on the left to become foggy, he controlled it, turned on the faucet of the furnace body, sprayed the aura into it, and then turned off the faucet as quickly as possible.

The left side entered the aura, stopped, and the right side began to output mana, into the alchemy furnace bottom rune, heating the furnace, so that the aura and steel can be organically combined at high temperatures.

Zhang Ziyu didn't stop until the mana in his body was exhausted.

Then he tiredly hugged the stove and found the Lingshi Sword and poured out the steel in the furnace.

Although it is still far away, it is the first step to get six samples. Zhang Ziyu is still very happy.

He went back to his study, put the six samples away, and meditated on the spot to regain his mana.

Not to mention anything else, after this consumes all the mana, the effect of cultivation is very good.

Zhang Ziyu directly replaced sleep with meditation, recovering his mana in the first few hours, increasing his cultivation in the middle hours, polishing his mana in the next few hours, and when he woke up in the morning, he had completely recovered his spirit.

After washing, Zhang Ziyu took his six "Linggang" samples to work.

Approaching the long holiday, the atmosphere of the company feels particularly impetuous, Zhang Ziyu himself is impetuous, but he came to work today but has no intention of working, he just came to the quality inspection equipment of the white prostitution company.

As soon as he arrived at the company in the morning, he went into the company's quality inspection room to test various properties of these six materials, first testing physical properties, such as surface condition, hardness, stiffness, toughness, etc.

Because the amount of material is limited, no chemical properties are tested.

He also used instruments to observe the microstructure of the material, such as the metallographic and microscopic crystal state of the material.

Zhang Ziyu saw in the morning and afternoon, and he didn't eat lunch in the middle, and he forgot to sleep and eat, which made the testers in the quality inspection laboratory admire: Zhang Gong is worthy of being the company's man of the hour, and he can still work so hard when he is about to take a holiday, which is really not an ordinary person.

It's just that......

Such a fortunate measurement, but the result made Zhang Ziyu very uncomfortable.

The spirit steel he tossed, six parts, six samples, whether it was performance or microstructure, there was no difference at all.

So...... is "Linggang" wrong? Is he wrong?

Holding a pile of data and six samples, he walked out of the quality inspection laboratory and looked at the dim sky in the distance.

Wrong?

What's wrong with scientific research?

Probably what went wrong......

Even if it's wrong, find out why, what's wrong.

Linggang, is it the wrong aura and steel? Or is the research method wrong?

He plucked up the courage in his heart again, and still felt that the project of cultivating immortal materials could continue to be studied.
