"You're not ashamed, the girl came to spank me!" Cheng Zhi squeezed in his mouth, but his head suddenly retracted, and he seemed to be really afraid of this nonsense.

"You ......" Sikong Nian also wanted to teach Cheng Zhi a lesson, but when he felt Lu Buqi's shining gaze, he seemed a little restrained: "I think he is his little brat, and he is joking......"

"I know, there's no need to explain. Lu Buqi replied indifferently: "It's good that you are here, I am planning to forge something again, if there is anything I don't understand, I'm afraid I will have to discuss it with you." ”

As soon as he heard that he was going to forge something, Sikong Nian's eyes suddenly lit up: "Okay, I'll pull the bellows for you!"

"No, it's my business to pull the bellows!" Cheng Zhi's little bald head popped up again: "You robbed me of my job that day, and I resolutely refused to let it today!"

Sikong Nian's brows drooped: "Stinky little bald head, like your master, he is a stingy ghost." ”

Lu Buqi patted Cheng Zhi's head with one hand: "The intensity of firepower needed today is relatively large, you can rest on the side, and it will save you from being a little family, and even your master and I will be scolded!"

In Sikong Nian's crisp laughter, Cheng Zhi muttered and grimaced at Sikong Nian, but also stood up: "Master, what materials do you need me to get for you?"

"I don't need those ordinary materials in the library today...... Lu Buqi shook his head and looked at Sikong Nian: "Use the lava core gold that Miss Sikong lost to me today!"

Sikong Nian didn't have the slightest expression of displeasure, obviously extremely free-spirited: "The lava core gold is hard enough, but if it is forged with lava core gold alone, the weapon can easily break." ”

Every metal has its own characteristics, Lu Buqi raised his brows slightly: "I'm about to test the effectiveness of this lava core gold, if you are willing to mention it, thank you very much!"

Sikong Nian shook his long hair lightly, and his expression was light: "Anyway, if you give you time, you can figure it out, I naturally won't be so petty." You can listen, if this lava core gold can be forged with red maple charcoal, it can strengthen the flexibility, of course, if there is no red maple charcoal, you can use the most ordinary charcoal powder, but the effect is definitely worse. ”

The activity of carbon powder is very large, and there is a similar process in ancient Huaxia, which is equivalent to a preliminary alloy forging, Lu Buqi nodded slightly: "In addition to this, do you have any suggestions in other links?"

"I've heard my grandfather say that lava core gold is a metal with strong compatibility, and its most precious thing is that it can help the fire and fuse a lot of special materials, such as the bones of the mysterious beasts, and some special jade. Just like Grandpa's Feather Blade, it is forged by fusing lava core gold and a jade called cicada wing jade. ”

Sikong Nian didn't hide his secrets: "It's just that those materials that need to be supplemented by lava core gold are very precious, and even they are not common in the Xuan Cultivation Sect, so don't be delusional!"

"Really?" Lu Buqi chuckled, but took out a square piece of jasper newt's back bone blunt thorn: "I wonder if this thing can be fused?"

After picking up Lu Kang and his wife from Yangze County, after talking to Long Buli about the Jasper Devil Newt, the three of them dissected the Big Mac in the backyard, Lu Buqi only left a small part of the Devil Newt Bone and some blood in the mustard ring, as for the backbone bone and some bone marrow of the Jasper Devil Newt, the skin and flesh are still stored on the body of Wu Regret.

"This is ......" Sikong Nian squatted down and tapped the blunt spur on her back bone, and then her face began to change: "This...... This is the outer Xuan bone ......"

Standing up suddenly, Sikong Nian looked at Lu Buqi, his eyes were full of surprise: "If I'm not mistaken, this should be the bones of some kind of mysterious beast born outside the body surface......"

Lu Buqi nodded: "It is worthy of being a person from the first family of sword casting, indeed, this is the back bone of the Mysterious Beast Jade Stone Devil Newt, which I obtained by chance." ”

"Oh my God...... It really is!" Sikong Nian sighed: "Such a big piece of bone is enough to build a heavy army!"

Lu Buqi pinched the tip of his nose lightly: "I have tested, this back bone is harder than steel jade, and it is very temperature-resistant, and the temperature that can turn steel into a liquid state is just to make it soften slightly." I wonder if this thing can be combined with lava core?"

Sikong Nian nodded: "I take back what I just said you were delusional...... Grandpa Tai once said that the bones of some mysterious beasts can be fused, and I think that the performance is so close to the bone of metal, it should be even better. ”

Lu Buqi nodded, and put the blunt spurt of the back bone, which weighed more than a hundred pounds and looked like a stone tablet, into the hearth of the big oven: "Then...... I'm tired of you!"

Thinking that she was about to participate in the creation of weapons with Xuan Beast materials, the blood of the swordsmith flowing in her bones was boiling, and Sikong Nian immediately lifted her skirt and tied it around her waist, revealing her ...... Wearing slender legs in close-fitting silk pants embroidered with sword marks, he sat in front of the bellows without restraint.

The flames rose up, and in the sound of Sikong Nian's even and orderly breathing, the highest temperature that a mortal fire could reach, and the dull spurt of the back bone shone with a black-gold luster in this raging flame.
