With a sincere smile on Lin Mu's face, Pan Shan pursed his lips, and finally walked out of the guild step by step.

Turning around, under the strange eyes of the eight elders, Lin Mu took the materials very calmly and walked up to the second floor and came to the refining room.

As soon as he sat down and took out the pile of pig iron and demon core savings bags, several elders walked in one after another.

"Lin Mu, why don't you come to our secret room?"

Guo Zhen glanced at the pig iron in Lin Mu's hand with fear, and said solemnly.

Lin Mu pondered for a while, looked at the pig iron and demon core in his hand, and then looked at the empty refining room, and gladly accepted Guo Zhen's proposal.

Here, no matter how you say it, it is also a place where the refiners conduct assessments, and he has been occupying it like this, and sooner or later he will be beaten by the group.

Just now, he made fun of Pan Shan like that, just to buy enough time to better study this batch of materials.

The material provided by the mysterious man was enough to make him even more dignified.

Led by Guo Zhen, Lin Mu was surprised to find that there was a third layer in this guild.

Moreover, the entrance to the third floor was actually in the elder's room, if there was no Guo Zhen to lead the way, no matter how strong his spiritual power was, he would not be able to find out.

I saw Guo Zhen knocking left and right on a wall, and a small door appeared on the wall opposite him.

"Illusion!"

Lin Mu was secretly shocked.

With such means, it must be a master!

"Let's go. ”

Guo Zhen tilted his head at Lin Mu, and then took the lead and walked in.

"This third layer is a small world of its own, and from the outside, it is actually the top of the guild, when the guild was first established, our president used it as a place to store treasured materials and for us to refine weapons. ”

Du Lao walked on Lin Mu's left side, introducing him as he walked.

Lin Mu saw it clearly, and Du Lao's somewhat cloudy eyes were full of eager worship.

"Our lord, as early as more than ten years ago, at the age of forty, he was already the only five-star refiner who was famous in the entire Eastern Continent, and the war spear he refined could be described as the best among the king's weapons, at that time, it caused a sensation in the entire continent. ”

In order to find an opportunity to become a Heavenly Fire Refiner, the president resolutely chose to give up his glory and went to the Western Continent. ”

As he spoke, the seven elders, all of whom were over sixty years old, couldn't help but breathe rapidly, and their eyes were wet.

"Remember his name, Qiu Yuan. ”

Under Du Lao's watchful gaze, Lin Mu nodded and secretly wrote down the name.

At the age of forty, he became a five-star refiner, and this kind of talent should be outstanding. But he was able to give up his glory, fade his aura and go to the Western Continent to start again, this heart had to be admired by Lin Mu.

Their president is truly in love with the refiner industry.

Thinking of this, Lin Mu couldn't help but get enthusiastic.

When you come to the third floor, you will be greeted by a dry stream of heat, and when you look at the light, the space on this floor is more than twice as large as the space on the first two floors combined, and several bookshelves are tightly embedded in the wall, surrounding this small world.

Looking up, the top is like the port of a huge furnace, with the bookshelves tightly surrounding it, and the dry heat flow in the air, this third layer is undoubtedly a huge furnace.

And they are in the middle of the furnace.

Such a handiwork and such a construction made Lin Mu dumbfounded and shocked.

The admiration for the president has also reached a higher level.

At this time, Lin Mu felt that even if Qiu Yuan was a strange person with unique ingenuity, it would not be an exaggeration.

Finding a place to sit down, Lin Mu took the materials out of the savings bag again, and at the same time, the eight elders who were still beside him instantly retreated and distanced themselves from him.

“......”

Looking at this group of old guys who ran faster than rabbits, Lin Mu suddenly felt speechless.

Putting the pig iron in his hand and observing it carefully for a while, Lin Mu did not find any difference between it and the usual pig iron.

"Don't feel it?"

Elder Yan, who was standing not far away and was staring at him closely, asked with a suspicious expression.

"Hmm. Lin Mu nodded stunned.

"Could it be that we got it wrong last time? Not because of the material?"

Elder Yan muttered as he walked slowly towards Lin.

Behind him, the remaining elders also followed him with puzzled expressions.

The seven heads formed a circle and pressed tightly above Lin Mu's hand, and in less than half a second, they were frightened like frightened birds, and quickly fled from this place.

Guo Zhen even exaggerated his vitality and ran to the bookshelf, staring at the pig iron in Lin Mu's hand with a frightened expression.

“......”

Seeing Guo Zhen with a cowardly face, Lin Mu was a little puzzled, was this really the Guo Zhen he knew?

Recalling the scene when they first met, Lin Mu felt for a while that this old man was possessed by something.

"Ahem..."

As if sensing that his actions were a bit exaggerated, Guo Zhen smiled with a standard smile, put his left hand slightly on his lips, and coughed lightly in disguise.

However, it has never taken a step forward.

Seeing the reactions of the elders, Lin Mu no longer doubted whether this pig iron was normal.

Absolutely not normal!

Thinking that he was different from theirs, Lin Mu easily understood that this was a gift carefully prepared for the refiner.

Throwing the pig iron into the furnace, a wisp of dancing flame formed from the tip of the index finger of his right hand in full view of everyone.

Without making a move, the flame drifted towards the pig iron by itself, like iron encountering a magnet, uncontrollably attracted by it.

"Whew!"

Surprised, a wisp of black stuff sprang out of the pig iron, and shot into Lin Mu's body like an arrow off the string.

Lin Mu was suddenly shocked, he didn't care about thinking about the scene that surprised him just now, and hurriedly looked inside to check his body.

The black thing had turned into a black mist at this time, swimming all the way to the dantian along his meridians.

Lin Mu looked at it solemnly, his heart moved, and he thought of the ordinary refiner's dantian, where there was the origin of fire.

Looking at the fog that was wandering left and right near his dantian but did not move, Lin Mu suddenly felt extremely lucky, if he had the origin of fire, it might not be what it would be like at this time.

"Treacherous?"

In his heart, Lin Mu shouted.

"Is there a way to force this mass out?"

"Nope. ”

The answer to him was two very short words.

“......”

Is it just to let it settle in its own body?

You know, his flames are all over the meridians of his body.

If it weren't for the fact that Wei Ming wrapped all his flames with vitality in the first place, he wouldn't dare to think about the consequences.

"Give it a try with your vitality. The treacherous voice sounded again.
