[Douluo] Xin knows

Hair crystals are crystals that contain different needle-like minerals inside.

So, what is golden hair crystal?

Golden hair crystal is the hair crystal in which the needle-like mineral inside is golden hair (rutile).

The one in Ning Rongrong's hand is like a golden hair crystal, with round, thin and many strands of hair; it is also like a titanium crystal, with a square shape, translucent and brown.

"This is plate crystal? It's a big piece!" Silong's eyes were full of shock: "Miss Ning, where did you find it? Such a big piece, at least one kilogram, I am willing to pay a thousand gold soul coins !"

Here, Jin Fajing was originally called Banjing, Tang San thought in his mind.

"President Silong, I'm afraid you will be disappointed. This plate crystal is of great use to Tang San."

Ning Rongrong really didn't know any plate crystals or titanium crystals, but she had heard Ning Xinli mention that Tang San had a hidden weapon called: Dragon Beard Needle, the material for making it was the thing in front of her eyes.

Therefore, Ning Rongrong certainly cannot resell this plate crystal to Silong.

After being rejected by Ning Rongrong, Silong turned and looked at Tang San: "Are you going to make him into a decoration?"

He couldn't figure out what effect plate crystals had on laymen.

"I didn't know you very well before, so I didn't mention it to you.

Our Tang Sect is a sect that specializes in making hidden weapons, and hidden weapons are sharp weapons like this. "

With that said, Tang San took out a golden bean the size of a grain of rice from the soul tool.

With a flick of his fingers, a golden line formed between him and the wall in front of him, and the golden line pierced deeply into the wall.

"In this slab crystal, there are at least a thousand of these golden beans.

Every golden bean, driven by the soul power, will extend such a golden thread, designed to break the soul master's defense. "

Do as the Romans do, since Silong said it was called Banjing, Tang San should change his words.

There is no need to struggle with the name.

Seeing this golden thread, Tai Tan's eyes lit up: "This, I guess it's the dragon's beard needle."

It turned out that they were also in the forging business, but what they forged was something called "hidden weapons".

No wonder, the teacher is so crazy.

For a blacksmith, what is more attractive than a good design drawing?

"That crystal plate is just an appetizer."

When everyone's eyes came over, Ning Xinli took her time and placed a piece of black ore with a chilly surface on the ground.

This piece of ore is only one meter away in length, and who would have thought that it would weigh hundreds of kilograms.

It's a good thing they have a storage soul tool, otherwise, let alone Oscar, it might not be easy for anyone to bring it back.

"I personally think that this piece of ore should be worth far more than that plate crystal."

This……

No matter Tang San, Tai Tan, or Si Long, they are all people who know the goods.

However, it is precisely because of knowing the goods that they feel more and more that something is not true.

If they are not mistaken, this ore...

But how is this possible?

After all, such a large piece...

If it is really as they imagined, it will be really incredible!

"Miss Ning, may I appraise this ore for you?"

No matter how unbelievable it was in his heart, Si Long suppressed the surprise in his heart for the time being, and asked Ning Xinli who was standing beside him for advice.

Ma Hongjun was quite puzzled by this: "Appraisal?"

Of course Ma Hongjun was not the only one who had doubts, the other people present also looked blank.

After getting Ning Xinli's permission, Si Long slowly raised his right hand, and a small pure golden chisel appeared in front of everyone.

One white, two yellow, three purple, one black.

Unlike Tang San and the others, Silong's seven spirit rings have four different colors.

Of course, this does not mean how good Silong is.

On the contrary, his soul ring configuration is very common in the entire soul master world, very common.

At this time, the Eight Shrek Monsters have already broken through to the level of the Soul Emperor.

Except for Tang San, the spirit ring configurations of the other seven people were all two yellows, two purples, and two blacks.

Compared to others, Tang San has an extra ten-thousand-year spirit ring as his fourth spirit ring.

Yellow, yellow, purple, black, black, black.

Although Tang San is only a soul emperor, he already has three ten thousand year soul rings.

Compared with Silong, it has two more ten thousand year soul rings.

"As you can see, like most blacksmiths, Silong's martial spirit is not suitable for fighting.

To become an excellent blacksmith, of course, there are reasons why Silong loves the industry of 'blacksmith' from the bottom of his heart.

However, at first, the reason why he chose to join the 'blacksmith' industry was not because Wuhun had no fighting power. "

Generally speaking, auxiliary martial souls also have little combat power.

However, those who have auxiliary martial souls can buff others or themselves, or remove debuffs.

"The martial spirit owned by Silong is a diamond chisel, good at identifying various ores and processing some delicate objects."

With a slight shake of Silong's right hand, the diamond chisel was replaced into his left hand.

After a burst of space fluctuations, a forging hammer appeared in his right hand.

For a moment, Tang San couldn't see its material.

Chisels, in general, are not used alone.

Even if it becomes a martial soul, it needs tools such as hammers and axes to cooperate with each other, and it cannot be beautiful alone.

I saw that Silong pressed the tip of the diamond chisel against the cold black ore, and held the special forging hammer in his right hand.

bang...

Following the action of Silong hitting the stone, the black ore burst out with a crisp sound.Immediately afterwards, traceable cracks appeared on its body, and the room temperature dropped a lot because of this.

"Cold Heart Iron Essence, really Cold Heart Iron Essence...

God, such a big piece? ! "

After the previous guess was confirmed, Silong was really a little dumbfounded, this is "cold heart iron spirit"!

"Why, President Silong doesn't plan to buy this piece of ore from my sister?"

Looking at Si Long who was in a sluggish state, Ning Rongrong blinked her eyes with a smile on his face.

Of course they won't sell this ore.

Although, they don't know the origin of this ore.However, as a direct disciple of the Seven Treasure Glazed Tile School, he was born with a very strong ability to appraise treasures. Ning Rongrong believed that its value must be very high.

"I want to buy it, but I have to afford it." Faced with Ning Rongrong's "ridiculousness", what kind of expression could Silong respond to Ning Rongrong's "ridicule": "One kilogram of pure gold is only 240 pieces Gold soul coins, and one kilogram of cold iron essence is sold for three hundred gold soul coins, which is a hundred times that of pure silver.

The cold heart iron essence in front of you, although it is only one meter in length, is at least a few hundred kilograms, that is to say, even if it is only one hundred kilograms, it is worth [-] gold soul coins. "

The subtext is that this chilling iron essence is far more than a hundred kilograms, and Silong's financial resources cannot afford it.

Rare metals are actually quite expensive.

So, since blacksmiths have the money to buy rare metals, why would Silong, as a new generation capable member of the Blacksmiths Association, worry about a mere [-] gold soul coins?

This, in fact, is not surprising at all.

The material is expensive, which means that the finished product forged based on this material will also be extremely valuable.

Great value, but someone needs to buy it.

Moreover, the blacksmith also needs to be able to forge and process this material.

It was obvious that Silong was not quite up to the mark.

"Miss Ning, the luck of the two of you sisters is too good! You won't have such rare metals in your harvest today, right?"

Those shops that sell rare metals, how can there be no people who identify metals.

However, Ning Xinli and Ning Rongrong still successfully "picked up the leak", which shows how strong their appraisal ability is.

Even Silong may not be able to accurately pick out this "chilling iron essence" from a large pile of rare metals.The reason why he can recognize it now is because Ning Xinli has placed it in front of him.

"This chilling iron essence is placed together with the tungsten steel.

One kilogram of tungsten steel is 32 silver soul coins.This cold heart iron essence weighs about 280 kilograms, totaling [-] gold soul coins. The boss erased the odds for us, and the final transaction price was [-] gold soul coins.

Not only that, the boss also kindly gave us a gift, that's it. "

As she said that, Ning Xinli spread out her palm, and a gray stone about [-] centimeters appeared in her palm.

[Miss Ning has such strong arms!

Although it looks quite small, who would have thought that she would hold such a large ore in one hand without changing her face. ]

Seeing Ning Xinli holding the boulder in her hand, Silong was secretly surprised.

"Although it's just a gift, I think its value seems to be higher than the previous plate crystal and cold iron essence."

"what?"

Silong heard the reputation and looked over, but his face was blank.

Based on his many years of forging experience, he couldn't tell at all what the ore in Ning Xinli's hands was.

"This is……"

At first, Tang San couldn't figure out the origin of this ore.

However, after Ning Xinli put it down, Tang San stroked it with his hands for a while, and finally saw some clues.

Ruoruo... If it is really that thing, then God bless the Tang Sect!

"You step back."

After everyone dispersed, Tang San looked intently at the gray ore.

Soul power surged, and a very ordinary-looking hammer appeared in Tang San's hand.

This is none other than his second martial spirit - the Clear Sky Hammer.

Seeing the Clear Sky Hammer in Tang San's hand, Silong finally understood why Tai Tan respected him so much.

Standing firmly with his right foot, with the toe of his left foot up, Tang San picked up the thirty centimeter ore in mid-air.Tang San turned his body, using his level 67 spirit power to exert power, he smashed the Clear Sky Hammer in his hand on the continuously falling gray ore.

boom--

Although, Tang San didn't add a spirit ring to his Clear Sky Hammer.

However, with the blessing of his soul power as high as level 67, the strength of this hammer can be said to be quite powerful.

Who would have thought that after a roar, the gray ore would not shatter.

Looking at the gray ore on the ground that had withstood Tang San's charged hammer but was still intact, everyone was stunned.
