"Huh...?" With a light sigh, Xiao Tianxing also followed the voice and looked over.

When he found the source of the voice, Xiao Tianxing's brows immediately furrowed.

"Is this voice...?" Out of curiosity, Xiao Tianxing also stood up.

Looking at the closed door in front of him with puzzled eyes, Xiao Tianxing subconsciously took a step forward.

But after taking this step, he also realized that this was not his home.

Turning his head to look at Lu Dan beside him, Xiao Tianxing also asked a little embarrassed.

"That...Uncle Lu, can I ask you, is there anything behind that door?"

"This ......!" Seeing Xiao Tianxing ask about what was hidden in his clean room, Lu Dan's face also showed a look of hesitation.

Because just now, Lu Dan saw the abnormality on Xiao Tianxing's face very clearly.

After hesitating slightly, he also asked Xiao Tianxing a question.

"It doesn't really matter if you tell the young marshal what's behind you, but can you tell me how you found what was behind that door? ”

"Oh! This one!" After hearing Lu Dan's question, Xiao Tianxing directly gave his own answer.

"Actually, it was just a moment ago that I felt and heard a slight tremor, and it was only after this tremor that I discovered what was behind the door. ”

"If I'm not mistaken, the thing behind that door must be a weapon, right?"

"Hiss......!" After listening to Xiao Tianxing's words, Lu Dan couldn't help but gasp.

"Just by the trembling in the air, I could feel something behind that door, and I knew very clearly that it was a weapon. ”

"Could it be that the legend in the fortress is true, the young marshal is a human-level swordsmith?"

"But even a human-level swordsmith can't make such an assertion just by this slight tremor, right?"

Looking at Lu Dan, who had never made a sound, Xiao Tianxing instinctively thought that he was embarrassment about whether he should go in and see the weapon by himself.

"That's... Uncle Lu Dan, I was reckless just now, you don't have to embarrass my question just now, let's take a look at other things here!"

After saying that, Xiao Tianxing also stood up and came to a huge wooden frame.

Carefully seeing the slightly lost expression on Xiao Tianxing's face, Lu Dan's wife also looked at Lu Dan who was stunned next to him.

"Boss, boss, you say something!"

"Ahh

"In charge, you can let the young marshal look at the 'clumsy' sword behind the door!

Listening to his wife's words, and looking at her eyes, Lu Dan immediately reacted.

"Oh!oh! Yes, yes!" After suddenly realizing something, Lu Dan also looked at Xiao Tianxing, who was observing the wooden frame.

"Hehe, don't get me wrong, young marshal, I was just a little stunned just now, and behind that door was indeed a forging sword. ”

"I heard that you are already a human-level swordsmith at a young age, so you can help me see this sword, what else needs to be improved!"

At the end of his words, Lu Dan also came to Xiao Tianxing's side and made a gesture of invitation to him.

"Young Marshal, please here!"

"Uh...!" After a slight hesitation, Xiao Tianxing also nodded slightly.

"Okay, I'll just see what the sword you forged, uncle, looks like!"

"Yan'er wants to take a look!" Seeing Xiao Tianxing go to see Lu Dan's long sword, Yan'er immediately ran to his side and wanted to go with him.

Holding Yan'er's little hand, Xiao Tianxing also looked at Lu Dan next to him and raised his own questions.

"That's... Uncle Lu, didn't you really want me to see the sword you forged just now?"

"Hehe!" Hearing Xiao Tianxing's question, Lu Dan also chuckled.

"It seems that my hesitation just now has caused you to misunderstand, young marshal! Actually, it's not like this, I'm just thinking about ......"

After explaining the reason to Xiao Tianxing, Lu Dan also raised a question to Xiao Tianxing.

"May I ask, young marshal, how did you discover that behind that door, there was a weapon being forged?"

Actually, I felt a slight tremor just now, and this tremor was very similar to the tremor of the blade of a weapon. ”

"And when I arrived at your house, I found that the water flowing out of your house's waterway seemed to be the wastewater produced after the sword was forged, so I made this guess. ”

"Oh! I see!" After a sudden realization, Lu Dan also took Xiao Tianxing to the door of his clean room.

"Crunch!" stretched out his hand to open the door in front of him, and Lu Dan also made a gesture of please to Xiao Tianxing.

"Young marshal, please come inside!"

"Then you're welcome!" After chuckling, Xiao Tianxing also took Yan'er's little hand and entered the room.

"This is ......" After seeing the situation in the room clearly, Xiao Tianxing's face was immediately full of surprise.

At this moment, in the middle of the clean room, there is a burning sword-casting furnace, and in this sword-casting furnace, there is also a longsword that has been burned red.

Xiao Tianxing was not surprised by this, after all, he had also seen a similar way of forging swords.

And the only thing that made Xiao Tianxing feel strange was that there was a rotating waterway around this sword-forging furnace.

Because it was next to the sword-forging furnace, the water in this waterway was also boiling at the moment.

Along the long sword stuck in the center of the swordsmithing furnace, several pipes branched out like whiskers, and another section of these pipes extended into the sink.

Walking quickly to the side of the sword-casting furnace, Xiao Tianxing also carefully observed these whiskers connected to the long sword.

After reading these mustaches, Xiao Tianxing's gaze fell on the sink next to the sword-casting furnace again.

After careful observation, Xiao Tianxing also saw clearly what was hidden in the sink, which was a trace of mercury.

"Is this ......!?" staring at the things in the sink and frowning, Xiao Tianxing also fell into deep thought.

Looking at Xiao Tianxing's appearance quietly, Lu Dan didn't say anything, just waiting for Xiao Tianxing to make his own judgment.

"This is the !! of quicksilver steel" In exclamation, Xiao Tianxing also suddenly looked back at Lu Dan, who was smiling and silent.

"Hehe! The young marshal really has good eyesight, and the thing in this sink is quicksilver steel!"

After being affirmed by Lu Dan here, Xiao Tianxing's eyes also fell on the long sword in the center of the sword-casting furnace.

"This long sword!?" After observing for a while, Xiao Tianxing also discovered the secret.

"This longsword is actually a longsword that has been formed, and it is now sucking the quicksilver steel in the sink through this special method. ”

"Such a keen insight, it really lives up to its reputation!" After secretly admiring himself, Lu Dan still didn't make any sound, just quietly waited for Xiao Tianxing's next observation.

Staring patiently at the beard tube extending from the long sword's fitness for a while, Xiao Tianxing found that these quicksilver steels seemed to be guided by this long sword, and they would flow along the beard tube to the sword body little by little.

"It's actually the long sword itself, guiding these quicksilver steels to slowly come to his body, so the material for casting this long sword must be very special. ”

After guessing in his heart, Xiao Tianxing also began to seriously observe the long sword in the sword-casting furnace.

After observing carefully for a while, the expression on Xiao Tianxing's face began to change from surprise to horror.

"This sword body is actually increasing its volume and length little by little through the quicksilver steel that is channeled up. ”

"And the quicksilver steel attached to it fits perfectly with the sword body itself, this is really the first time I've seen this sword-casting method!"

Listening to every word that Xiao Tianxing said, Lu Dan also completely believed that Xiao Tianxing in front of him was a human-level swordsmith, and he was also a very clever human-level swordsmith.

After staring at the long sword in front of him for a long time, Xiao Tianxing finally couldn't figure out what material the long sword in the sword casting furnace was.

"That Uncle Lu, what kind of material is your long sword? I really can't see it, can you tell me if it's convenient?"

"Hehe! Of course you can!" After agreeing with a smile, Lu Dan also gave the answer that Xiao Tianxing wanted.

"The material of my long sword is actually made of magnetic anode steel, so there will be a certain adsorption force on the top of the sword. ”

"Magnetic pole anode steel?" Hearing this unfamiliar word, Xiao Tianxing's brows also frowned, and then he also hugged his fist at Lu Dan.

"This is the first time I've heard of this magnetic pole anode steel, I hope my uncle can explain it to me in detail!"

"No problem!" said cheerfully, and Lu Dan also gave a detailed explanation to Xiao Tianxing.

"In fact, there are two kinds of magnetic steel, one is yang steel, the other is yin steel, and they are actually a kind of natural steel. ”

"But the only difference is that this kind of magnetic pole steel can adsorb certain metals, while the metals adsorbed by yang steel and yin steel are also fundamentally different. ”

"As the so-called opposites attract, the attribute of quicksilver steel is biased towards cold, so it will be absorbed by my long sword. ”

In this adsorption process, the quicksilver steel will also fully fuse with the sword body, thereby increasing the strength and power of the sword body. ”

"Of course! This kind of attachment will only make the sword body bigger, so the sword technique that focuses on dexterity is not suitable for this method. ”

"Oh, I see!" After suddenly realizing it, Xiao Tianxing stared at the long sword in front of him and sighed.

"It's like this long sword, which is constantly devouring things, and then growing!"

"Hehe! The young marshal is also right when he says this, but I have heard that some weapons can indeed improve their quality by devouring some materials of the same kind. ”

"However, a weapon of that level must be a weapon that has entered the quasi-ground level, and the consciousness above it must also be clear. ”

"Of course, I've only heard of such a possibility, but I don't know if it will work out!"

Although Lu Dan said it unintentionally, after Xiao Tianxing heard these words, a strange look immediately flashed in his eyes.

"Young marshal, I wonder if you have any pointers for this sword I forged?"

"Ahh ”

"In this case, we may be able to improve the quality of your long sword. ”

"Fusion Soul Crystal!?hehe!But I don't understand that method!" Lu Dan also smiled bitterly at Xiao Tianxing's suggestion.

"Hey, you don't understand, I understand, I'll help you!"
