"Humph!"

Seeing An quietly shrinking to the side, eager to find a piece of cloth to cover himself with Lieshan and Lin Chenxing, Elder Wei snorted coldly and glared at them, but he didn't make any more moves.

Lin Chenxing obviously heard Lie Shan quietly breathe a sigh of relief, and then he also understood that this turmoil was temporarily avoided.

"Go to the warehouse and get four more!" Elder Wei stood in front of the refining platform and thought for a while, then commanded directly.

"Yes, master!" Hearing the order, Lie Shan was like an amnesty, and quickly left in Lin Chenxing's jaw-dropping, and the reaction was so rapid that Lin Chenxing, a dark martial artist, could hardly see his figure clearly.

In the depths of his heart, he rolled his eyes fiercely at the Burning Mountain, Lin Chenxing thought about it and then spoke: "Elder Wei, can you let the disciple see the spirit iron?" ”

To be honest, it was a little risky for Lin Chenxing to open his mouth at this time, but he looked at Elder Wei's performance before and after, as if his mood was not as bad as expected, it seemed to be ..... Already used to failure?

At least, judging from the occasional revelations from the Burning Mountain Pass, it was not a matter of a day or two for Elder Wei to try to enhance the performance of the Spirit Iron.

Lin Chenxing couldn't help but guess a little, could it be that after the first few failures, Elder Wei lost his temper, causing too much psychological shadow to Lieshan? If not, why would a person who usually looks quite stable react so much when the furnace is opened today?

"Whatever, just a bunch of scrap metal!"

Elder Wei didn't react much when he heard this, frowned as if he was thinking about something, waved his hand, and responded casually.

"Thank you, Elder, for making it happen!"

After Lin Chenxing thanked him, he took a few steps forward, came to the waste basket, and used iron tongs to pick out a piece of fine iron that had faded red but had not yet completely cooled, and observed it carefully.

This was his first contact with Lingtie, and it was not that he had searched for relevant information in the pile of idle books in the Zangwu Pavilion before, but it was obviously impossible to find it.

The level of spiritual iron is far above that of fine iron, at least only martial artists of the Qi Eating Realm and above are eligible to use weapons refined by Spirit Iron, and the first floor of the Hidden Martial Pavilion does not have any relevant books on the Qi Eating Realm.

After a brief observation, Lin Chenxing found that the surface of this piece of spiritual iron, which had been conceived and raised for twenty days under high temperatures, did not produce much oxide layer, which made him very surprised.

It is important to know that even if the refined iron block is more than ten refined, just a short time of heating will produce a layer of oxide on the surface.

"Lingtie is really extraordinary!"

While secretly praising in his heart, Lin Chenxingzi carefully observed the spirit iron in his hand, he wanted to know more about the properties of this metal, in order to make some reasonable speculations.

A deep understanding of the properties of metal materials and their mechanisms is what he is best at, and his familiarity with these things far exceeds his understanding of forging techniques and martial arts.

After all, it was something he had been systematically studying for seven years, and that knowledge gathered the wisdom of an unknown number of elites in the field of materials. That's systematic!

Why is Lin Chenxing so concerned about this?

The interest brought by the profession is one thing, and the more important thing is that he wants to use it as a stepping stone for himself!

If he could successfully rely on his theoretical knowledge in the field of materials to help Elder Wei find a feasible method or direction, he believed that he would definitely be able to attract Elder Wei's attention! If it works well, it will definitely bring a lot of benefits to his own martial arts cultivation!

As for whether it will succeed or not? Lin Chenxing was not sure at the moment, he needed to carefully understand the information about Lingtie before he could try to use the knowledge he had to deduce.

Whether it's scheming or utilitarian, Lin Chenxing doesn't care. If it is done, it is also his own ability!

If you want to be recognized by others, you naturally have to show your own value!

"Senior Brother Lin, what are you doing? Come and help! Just as Lin Chenxing was carefully observing the spirit iron that had failed to conceive, Lieshan had already returned from the warehouse.

"It's coming!"

The three of them quickly put four palm-sized pieces of spirit iron into the furnace tripod again, and then Elder Wei personally adjusted the size of the fire vent and reset the temperature of each furnace tripod once before it was completed.

"Master, how long will it take this time?" Lieshan asked on the side, and Lin Chenxing pricked up his ears when he heard this.

"A month!" After saying that, Elder Wei raised his feet and walked towards the crossing, obviously preparing to leave.

"Senior Brother Lie, stay here!" Seeing that Lieshan was about to leave, Lin Chenxing hurriedly opened his mouth to stay.

"What's the matter with junior brother?"

"Senior Brother Lie, I'm very interested in Lingtie, but I haven't found a single related book after rummaging through the Hidden Martial Pavilion. I wonder if my brother has any relevant books in his hands? Can you lend me a look? Lin Chenxing put on a studious posture and asked expectantly.

"Hmm...... I should have it, I'll go back and help you find it later, and I'll bring it to you tomorrow. ”

"Thank you, brother!" Lin Chenxing said gratefully.

"Little thing, you take a good look at the stove!"

"Senior brother, go slowly!"

After the two of them left, Lin Chenxing came to the side of the smelting table again, picked up the piece of spiritual iron and looked left and right, but unfortunately, except for some things on the surface, it was difficult for him to see anything.

Metallurgical microscope? No!

Scanning electron microscopy? No!

Transmission electron microscopy? No!

X-ray diffraction? Nor did it!

There was not a single instrument in his hand, and Lin Chenxing could only stare dryly! It's hard for a good woman to cook without rice!

There was really no way, Lin Chenxing had to use the stupidest method to roughly estimate the hardness and other properties of this so-called spirit iron.

Putting this piece of spirit iron, which was still slightly warm, on the forging table, Lin Chenxing picked up a forging hammer and smashed it down.

"Dang!"

After the crisp sound, Lin Chenxing took a closer look, and there was no mark left!

"It's really hard! In that case......"

Lin Chenxing clamped the spirit iron block, raised the forging hammer high, exerted all his strength, and fell heavily.

"Dang!"

Listening to the louder voice than before, Lin Chenxing grinned, put down the forging hammer, shook off his right hand, which was a little numb by the force of the shock, and observed the spiritual iron on the anvil again, but found that there was only a little white mark left on it!

Lin Chenxing: "......"

His strength at this time had already exceeded 1,500 catties, but he tried his best to go down with a hammer, but he only got this result!

Even if the spirit iron was not heated at this time, this hardness was somewhat beyond Lin Chenxing's imagination!

"It's a material used to forge weapons for martial artists above the Eater Qi Realm! It's just a burnt rough embryo, and if it's been carefully forged and processed to make a real sword, then it's ......."

Lin Chenxing smacked his lips, he felt terrible when he thought about it!

The comparison of Gu Yanfeng's and Lin Dong's weapons is a living example!

Lin Dong, who had just broken through to the Transformation Yuan Realm, had not yet changed into a spirit iron-level weapon, so structurally speaking, the long stick that should have been stronger was indeed cut off by Gu Yanfeng's spirit iron-level long knife, and even almost lost his life.
