Su Xuan went to greet Bao Ben first.

"I've seen Grandpa Guo, it's been a long time." Su Xuan bowed slightly.

"It's been a long time since I saw Lord Su."

Bao Ben leaned his head towards Su Xuan and whispered, "Boy, why didn't you bring wine here after not coming for so long?"

"Honestly, boy, I'm poor now. You see, there's ...... left in your pocket."

Su Xuan pulled it casually and pulled out a silver ticket with a face value of one hundred taels.

"Hey, hey, hey."

The two looked at each other and smiled, and everything was silent.

"Grandpa Guo, I'll go and see the progress of the underground factory, and we'll talk later."

"This kid!"

Su Xuan hurriedly ran behind Zhao Ling'er, only to see Zhao Ling'er's expression unusually focused.

Zhao Ling'er was holding the parts of a crossbow in his hand, and he seemed to be a little puzzled.

"Why don't you study the bed crossbow?" Su Xuan asked with a smile.

"Well, the bed crossbow is no longer difficult, I want to see if this crossbow can reach the power of a compound bow." Zhao Linger said.

Difficult. Su Xuan said.

"Is it difficult?" Zhao Ling'er asked again.

"The crossbow is only so big, no matter how complex the structure is, the charging power is limited. The compound bow is very easy to use, don't study the hand crossbow, I'll take you to make more advanced weapons and equipment another day." Su Xuan said.

"Okay!"

Zhao Ling'er suddenly reacted, this is not Su Xuan's voice.

So she turned her head sharply, and after seeing Su Xuan, she hung directly on Su Xuan's neck.

"Little Xuanzi! You're back, I haven't seen you for more than a month, you've lost weight!" Zhao Ling'er shouted.

"Okay, okay, come down, so many people are watching, what kind of system is it?" Su Xuan didn't have a good airway.

"Oh."

Zhao Ling'er hurried down

Come.

Su Xuan found that this little girl had grown up a lot.

"I'll ask you a question, do you know how to craft a sword?" Su Xuan asked.

"It's simple, it's not easy." Zhao Linger said.

"How?"

It's easy to create a normal sword, gun, sword and axe. But it is very difficult to build a top-notch sword, especially a sword. Zhao Linger said.

She is a craftsman, and she really has more than just a study of miracle skills.

Su Xuan estimated that she also started with the simplest sword.

If it is easy to build a top-notch weapon, all craftsmen in the world can do it.

There are far fewer top-level swordsmiths than swordsmen.

"So, you can build it?" Su Xuan asked.

"Yes, yes, what are you asking for?" Zhao Linger asked rhetorically.

"I haven't had a weapon to hand over, and I'm trying to find someone to make one." Su Xuan replied.

"You want me to forge a sword? I've never tried forging a sword, but if there's a good material, I can try the water." Zhao Linger rubbed her hands and said.

"Do you know how to craft a spirit sword?" Su Xuan asked again.

"You need a suitable sword embryo, the sword spirit is the creation of heaven and earth, the mystery of invading the sun and the moon, you can meet but not ask for it. If you want to build a sword, I can try it, as long as I have good materials. But if you need a spirit sword, you need a sword embryo in the true sense." Zhao Linger explained.

"It's so complicated, I thought it would be enough to have iron." Su Xuan said.

"That's all I know, you can go to Grandpa Guo and ask, he is the best craftsman in the world, and he knows more about sword forging than me." Zhao Linger said.

"Okay!"

Su Xuan hurriedly sent someone to buy good wine and food.

During this period, Su Xuan asked Zhao Linger to take him around the underground factory.

After the wine and meat arrived, Su Xuan pulled Old Man Bao and sat down together.

"Kid, yes, insightful!"

"Grandpa Guo, do you know how to forge swords?

Su Xuan asked.

Originally, Su Xuan thought that there was a specialization in the art industry. Mr. Bao is good at doing big projects, but he is not good at these small skills.

He must have thought it wrong.

"See those two axes of Xiaoxing?" Old Man Bao asked.

"Not only have I seen it, but I have even learned it."

The pair of flying axes in Bao Xiaoxing's hand had a hole in his thigh.

Now that I think about it, my thighs still hurt, but the scars are still there.

"It's made by old decay, isn't it?" Bao Ben laughed.

"Drink and drink."

Su Xuan came to his senses and hurriedly poured wine for the old man.

"Boy, it's really on the road, hehe, drink!"

"Old man, how should this spirit sword be made? Where should the right sword embryo come from?" Su Xuan asked.

"The sword embryo of the spirit sword is hard to find. Maybe it's a stone, or a leaf, or a flower...... If you find a sword embryo, find a good piece of dark iron, and combine the two into one, you can become a sword." Baoben explained.

In this way, Su Xuan probably understood.

It means that when the sword is cast, the soul is given to the sword, so that the spirit sword is completed.

Otherwise, even if the sword made of the best Xuaniron stone is, it is still a dead sword, and it cannot become a divine weapon.

"It's that simple?" Su Xuan asked.

"Simple? Hey, hey......"

Bao Ben smiled mysteriously and said, "This process of merging the two into one requires a great deal of effort from the swordsmith. Control of the heat, forging

The strength, the length of tempering, the control of temperature, etc., but if there is a link that goes wrong, the sword embryo is damaged, and the sword will not succeed."

He raised his head slightly and took a sip of his wine.

"Swordsmith is the rarest profession in the world. Even the Sword Sect, which has been inherited for more than five hundred years, has only one sword forger in this generation. The last swordsmith had to go back eighty years." Bao Ben said.

"Why are swordsmiths so scarce?" Su Xuan asked again.

"The swordsmith in the old man's mouth is not an ordinary swordsmith, but a swordsmith who can create a spirit sword. The world's famous sword 12 is the pinnacle of sword casting history. And the true spiritual swords, in the whole world, may not exceed five hundred." Bao Ben said.

"Didn't you say that the Natal Flying Sword needs to be conceived with a spirit sword?" Su Xuan asked.

"So, not every swordsman has the opportunity to get the Natal Flying Sword." Bao Ben laughed.

"Doesn't it mean that the three-grade sword cultivation basically has a natal flying sword?" Su Xuan asked again.

"Good fellow, who told you?"

Bao Ben first asked, then nodded and said, "There's nothing wrong with saying this, the sword cultivation that has realized the imperial sword technique, and can reach the third rank realm or above, is already a leader."
