So the ghost old man took Feng Yun out of their place of residence and into the jungle. After a while, the two came to a cave.

"Remember the road, this is a fire, and you may spend a long time here." The ghost old man walked in front and said slowly.

Feng Yun looked at the cave all the way, and secretly said in his heart: "Is it the earth fire, it is somewhat similar to the earth fire hall of the Lingtai Sect back then." It's really suitable for my cultivation. ”

The two of them walked for tea time one after the other, and finally arrived at the place. The environment here is naturally not as elaborate as the Earth Fire Hall of the Lingtai Sect, but this place only belongs to the ghost old man, no one will disturb him, and they have all the forging tools, which is more than a few points better than the Earth Fire Hall.

"This is it." The ghost old man walked towards the furnace built next to the earth fire mouth, and said to Feng Yun, "After this earth fire furnace is opened, it can introduce the earth fire, whether it is the Dixing Stone or the Xuanyin Crystal Ore, as long as you have the ability and materials, the medium-grade Xuanqi can also be built here." ”

"Oh oh oh!" Feng Yun couldn't help but get excited, with the previous study of the formation, he was now full of interest and expectation in refining weapons, and he couldn't wait to make a peerless good knife right away.

Seeing this, the ghost old man smiled: "Don't be too happy too early." As he spoke, he flicked his fingers, and the mechanism of the earth fire furnace was suddenly opened, and in a moment of practice, a hot breath gushed out from the mouth of the furnace.

Feng Yun suddenly remembered something at this time: "Master...... By the way, it doesn't matter your body, right? ”

The ghost old man replied, "Don't worry, nothing will happen for a while." As he spoke, he took out a piece of crystalline ore from his sleeve, "You know the basic forging process, right?" ”

Feng Yun nodded, he had already read a lot of knowledge about forging from the books given to him by the ghost old man.

"In that case, let's use this piece of crystal ore to get a knife out first."

"Oh......" Feng Yun couldn't help but be a little disappointed when he heard this request, he thought that he had come here to officially start refining weapons, but the result was a knife

"This starting point is a bit too low...... "He scolded in his heart, but he still did it honestly. Although it was the first time forging, the movements couldn't help but be a little jerky, but Feng Yun had read a lot of forging books, and he had deduced it more than a few times in his heart, and he was barely confident, but there were no major problems, plus his original strength was not small, and he had already laid a knife embryo in a short time.

After that, it was tempering, burning, and polishing, and the ghost old man watched in silence as Feng Yun completed all the processes until a shiny knife blade was placed in front of him.

Feng Yun looked at the work he had created for the first time, and the shiny blade made him feel good.

However, after a strange gaze from the ghost old man, he couldn't help but feel compassion: "Uh......"

"Are you satisfied?"

Feng Yun heard this, scratched his head, hesitated for a while, and said honestly: "I think...... It's okay. ”

The ghost old man nodded: "Well, this level is enough to be a little blacksmith in the mortal world." ”

After Feng Yun heard this, his old face immediately turned red, and he muttered, "It's not like it......"

"Of course not! Ordinary blacksmiths can use refined iron ore to make a knife that can only cut meat, and you can also use crystal iron ore to make a knife that can only cut meat! You're so much better than a blacksmith! ”

Feng Yun was scolded and a little aggrieved: "How can it be, this is a crystal iron mine, you can cut stones, how can you only cut meat." ”

"Hmph." The ghost old man snorted lightly and grabbed Feng Yun's knife: "Look for yourself, this pattern is messy, you can listen to this sound again", as he spoke, he flicked his fingers towards the blade.

The two flicks were in different positions on the blade, and two different slight sounds were made. After doing it, the ghost old man looked at Feng Yun again and said, "Did you see it, did you hear it, you can use your divine sense to take a look again." After speaking, he threw the knife to Feng Yun.

Feng Yun held it in his hand, learned from the ghost old man to look at it and flicked it, and finally carefully observed the entire knife with his divine sense, and finally couldn't help but say dejectedly with his neck: "...... The disciple knew that he was wrong. ”

"Since you know your mistake, let's go back to the furnace and try again."

"Yes." Feng Yun put away his relaxed attitude this time, and his expression became serious, and all the processes were completed very carefully. After a while, a knife that sold much better than just now appeared in front of the ghost old man.

The ghost old man looked at it, picked it up and played it again, this time the two sounds were already very consistent, Feng Yun couldn't help but show a smile, however......

"Yes, you can go to the ordinary world to open a blacksmith shop, and you won't starve to death with this craft."

Feng Yun's face suddenly collapsed: "It's not like it......"

The ghost old man glanced at Feng Yun and said, "Relax your body and don't resist." ”

"Oh." Feng Yun seemed to have guessed what the ghost old man was going to do. Sure enough, in the next moment, an invisible force covered Feng Yun's entire body, and his body began to take another piece of crystal iron ore handed by the ghost old man and walked towards the earth furnace without obeying the call.

After the crystalline iron ore was melted into an iron embryo, Feng Yun's body took it out and fixed it, grabbed the iron hammer and began forging it again. Feng Yun carefully felt the movements of his body, and observed the changes in the hammer and the knife embryo, the whole process was no different from what he had done before, tempering, quenching, burning the blade, and polishing.

Under the control of the ghost old man, Feng Yun's movements became more sophisticated, and the speed of completion was naturally much faster than Feng Yun's, and it didn't take long for a new knife to appear in Feng Yun's hand.

Feng Yun was holding this knife, and he didn't need to look at it much, the sharp aura emitted by the knife was already telling the difference between it and the garbage that Feng Yun had created before. Feng Yun closed his mouth, looked at it for a while, and then flicked it twice, and sure enough, a pleasant trembling sound came, and he couldn't help but sigh, "It's all crystal iron ore, what I just hit is indeed just rags." ”

Seeing this, the ghost old man took the new knife from Feng Yun's hand, and smashed the two knives together in front of Feng Yun, only to see that the knife created by the ghost old man's control of Feng Yun's body actually cut into the knife forged by Feng Yun without hindrance.

"Qiang ......" The knife that Feng Yun had created earlier was suddenly cut in half, and half of the blade fell to the ground, making an unpleasant trembling sound.

"Do you know what you're doing wrong now?"

Hearing this, Feng Yun looked at the half of the sword body on the ground and fell silent, "There is almost no difference in the process behind, it's just that the master is more skilled, so there won't be such a big difference, and sure enough, it's still time to build...... That kind of hammering. ”

As if he saw what Feng Yun was thinking, the ghost old man spoke: "Do you think that the hammer method I forged is special? ”

Feng Yun hesitated for a moment and nodded: "Master's hammer technique is like a drizzle of continuous rain, and the force of each hammer is not bad at all. ”

The ghost old man nodded: "This time you use your divine sense to observe for yourself again." ”

So the ghost old man controlled Feng Yun's body and returned the broken knife to the furnace again, this time Feng Yun followed the ghost old man's instructions, leaned out his divine sense, endured the scorching fire of the earth and observed the ghost old man's tempering.

After a while, he was shocked, under the observation of his divine sense, he finally discovered the terrible thing about the ghost old man, unless the ghost old man took the initiative to change the position, each of his hammers fell in the same place, it was not bad at all! Feng Yun asked himself ten hammers, no, among the thirty hammers, he might be able to have two hammers that can do it like this.

Another knife that actively exuded a sharp aura appeared in Feng Yun's hand.

Seeing his appearance, the ghost old man smiled and asked, "Understood?" ”

Feng Yun nodded: "...... I see. ”

"Can you do it?"

Feng Yun sighed and shook his head: "It's difficult. ”

"Ha, it's really hard, but it's not about striking iron, it's about controlling yourself." The ghost old man said with a chuckle.

"Take control of my own ......"

The old ghost man turned off the mechanism of the earth stove and walked out, saying as he went, "Actually, this is what all monks should do, but most people don't do it. It's about being in control of ourselves. ”

Feng Yun followed behind him, silently listening to the ghost old man's teachings.

"What do we usually spend the most energy trying to control? It is our true element, so after deliberately honing it, some monks are able to use spells as armours. But what about our bodies? It is precisely because we are born to be able to control it that we relax our control over it, but if we can't even control ourselves, how can we better control others and control the Dao? ”

Feng Yun pondered the ghost old man's words. He remembered the scene when he was in Lingtai Sect, when he was competing with Li Huai, he was only a little short of being able to cut the stick shadow, but unfortunately he was still a step slower, and he couldn't escape and was seriously injured, if he could be like a ghost old man falling a hammer at that time, every knife was cut in the same position without a single difference, maybe he could escape from the stick prison one step earlier, and defeat Li Huai who was casting spells, so as not to be so embarrassed later.

"Especially as a body refining cultivator, your body is your biggest weapon, if you can't even use your own weapon, then it's no wonder that you die at the hands of others."

"Disciple understood." Feng Yun was humbly taught.

"Hmm. So from tomorrow onwards, you have to learn to control your body. ”

"Yes."

Hearing Feng Yun's serious answer, the ghost old man couldn't help but smile mysteriously: "Hehe, you have to be ready." ”

"Huh?" Feng Yun was stunned for a moment, and then couldn't help but feel a little apprehensive, he could see that the ghost old man usually didn't look tight, and he didn't even care much about the absurdity of Feng Yun and Du Huaiyi's change of generation, but when it came to the business of cultivation, he couldn't tolerate a little sand in his eyes, and he didn't know what kind of homework would wait for him in the future.
