After briefly testing the hardness of the spirit iron, Lin Chenxing didn't toss anymore.

Because it's really useless!

His strength was not enough to completely crack the crack spirit iron block, even after heating. Originally, he also wanted to see the shape of this fracture surface, so as to further deduce the properties of this spirit iron.

"It seems that I can only count on the information that Senior Brother Lie brought me!"

Throwing down the spirit iron, Lin Chenxing entered the cultivation. After nearly twenty days of cultivation, he already felt that the tendons in his body were much stronger and more flexible, and the tension between his body stretches was also more intense.

Similarly, after half a month of adaptation and tempering of his body, at this time, he was able to last for more than half an hour for each fire refinement, that is, more than four quarters of an hour!

As for when he will be able to reach the point of "muscles like a dragon" mentioned in the exercises, Lin Chenxing still has no bottom in his heart, no one to guide him, he can only grope his cultivation all the way, waiting for the day when the water will come to fruition!

However, what made Lin Chenxing a little worried was that his Wind Refining Nine Styles had fallen for nearly twenty days and had not been cultivated.

There is no way, the Gangfeng of the Bone Removal Cliff can only meet the requirements of practicing the Nine Styles of Wind Refining at night, and he has to guard the Ding Furnace here every night during this time, taking the opportunity to cultivate the Nine Styles of Fire Refinement!

The time of one night was like a blink of an eye for the cultivation of the martial arts, and soon, Lin Chenxing heard the sound of footsteps coming from the Yongdao.

"Elder Wei is early!"

"Senior Brother Lie is early!"

"Here, these are all idle books, I haven't opened them in a long time! Take a look for yourself! Lieshan was carrying a wooden box in his hand, which looked quite old, and some dust could be seen on it.

"Thank you, brother!" Lin Chenxing hurriedly stepped forward to take the wooden box and held it in his hand, like a treasure.

"Little things, you're welcome, you go back and rest!"

"Okay, senior brother, then I'll go first!"

With a box of books, Lin Chenxing finished breakfast, returned to his residence, first slept beautifully, and then completed the cultivation of the three-character swordsmanship, and then opened the wooden box.

"That's enough for me to watch for a while!"

Looking at the wooden box full of books in front of him, Lin Chenxing felt very satisfied.

During this period of time, the miscellaneous books on the first floor of the Zangwu Pavilion had almost been turned over by him, and soon he would fall into the embarrassing situation of having no books to read, which was the most important way for him to understand this world.

After quickly flipping through a few books, Lin Chenxing found that these books were basically related to refining tools, with basic common sense introductions, common metal and mineral illustrated books, and some related to forging and smelting.

"That's right, let me have a good look at ......"

In the following month, Lin Chenxing practiced swords, read books, practiced the Nine Styles of Fire Refining every day, and occasionally asked the familiar Lieshan for advice on some refining matters, and the relevant information of Lingtie was naturally the object of his focus.

In this way, soon, the January period had arrived, and after Elder Wei opened the furnace, he once again harvested four pieces of spiritual iron that had been conceived and discarded, and even its strength and toughness were not as good as the previous furnace. When the thickness of the kankan is about an inch, cracks appear.

Elder Wei, who was extremely resolute, ordered Lie Shan to take four pieces of spiritual iron again, and when he was about to open the furnace again, Lin Chenxing spoke.

"Elder, can you listen to your disciple first, and then it's not too late to open the furnace!"

As soon as he said this, there was silence in the space in the belly of the mountain for a while, and then he heard Lieshan speak: "Senior brother, don't talk nonsense, delay the master's pregnancy and cultivation of spiritual iron!" ”

Saying that, Lie Shan also gave Lin Chenxing a vague look, signaling him not to talk too much, in case he angered Elder Wei, who was not in a good mood, it was not a joke. He didn't suffer much before!

Lin Chenxing first gave Lie Shan a reassuring expression, and then stared at Elder Wei with burning eyes, with an indescribable confidence on his face.

In the past month, he has carefully read all the books given to him by Lieshan, and he usually finds opportunities to ask Lieshan for advice, and at this time, he already has some understanding of the material of Lingiron.

Although the information he got about Spirit Iron was still pitiful compared to the knowledge of some Blue Star metals such as steel in his mind, it was enough for him to make some speculations.

He was seventy percent sure that he could change the technique in the process of conceiving the Spirit Iron so that Elder Wei would get the result he had been hoping for.

Seventy percent of the certainty is enough for him to gamble!

The big deal is to anger Elder Wei and suffer some suffering! As for kicking him out of here? This possibility should be quite small!

"Shut up!"

Elder Wei first scolded Lie Shan, and then said at Lin Chenxing: "Boy, tell me about it, I hope you're not talking nonsense!" ”

"Thank you, Elder! Don't dare to deceive the elders, this month, I have been thinking about a question, the elders want to conceive and raise the spirit iron, so as to further improve the quality and performance of the spirit iron, but since it is conceived and raised, if it is only calcined at a very high temperature, is it really suitable? ”

"Since it is pregnancy, shouldn't there be a gentle environment for Lingtie to transform itself, so as to achieve your purpose as Elder?"

Lieshan: "......"

"Well, although it doesn't make sense, it seems to make some sense!" After listening to Lin Chenxing's simple two words, Elder Wei thought for a moment before speaking.

Lin Chenxing couldn't help but complain in his heart when he heard this: "Of course it's bullshit, I'm just bullshit!" But the real mechanics can't tell you directly! ”

Of course, the confidence he had to stand up and speak was not the two sentences he had just gotten to talk about, what kind of pregnancy and nurturing needed a gentle environment to let Lingtie grow and change on its own.

In fact, when Lin Chenxing learned some of the characteristics of Spirit Iron from Lie Shan, he knew the reason for Elder Wei's failure.

The so-called spiritual iron, to put it bluntly, is an ultra-high-strength alloy.

The reason why Lingiron has such high strength and toughness is actually due to the interaction of some special substances in it, which is called the strengthening phase by the Blue Star people.

The principle of this is the same as that when the ancient people of Blue Star added straw to the mud, the walls of the house made by mud bonding would become stronger. It's just that what's involved here is more elaborate and complex!

Generally, in the spirit iron that has just been refined, these special substances are not evenly distributed, and there may be a lot of them gathered in a certain place, and the area around it will be naturally distributed relatively little, which is the so-called segregation in the field of materials, and the existence of this segregation phenomenon will inevitably cause the overall performance of spirit iron to decline.

Although repeated forging can improve the distribution of these special substances, it does not completely eliminate the problem of uneven distribution.

It's like stuffing a piece of hard candy into a piece of dough, even if you use a strong hammer to knead the dough, it will only break the candy into smaller pieces, but it does not guarantee that the candy will completely turn into powder and be evenly distributed in the dough.

But if you heat the dough a little so that the candy melts completely, and then knead and beat it thoroughly, the whole dough will be sweetened, and the sweetness will be about the same in all positions!

Elder Wei's essential principle of pregnancy and cultivation of spiritual iron is like this, his idea is right, and the general direction of the method is also right, but he used too much force!

To put it simply, Elder Wei didn't control the heat when he was heating the dough, and directly burned the dough!

What's worse is that he himself has always thought that the temperature is not high enough, and continues to raise the temperature!

If you are lucky, you don't need Lin Chenxing to remind you, Elder Wei may be able to think of lowering the temperature when the temperature can't rise.

But it's impossible to say how much time this process will take, and even, in this process, it is unknown whether Elder Wei will finally deny this idea of improving the performance of the spirit iron because of his continuous failures!
