Although Capri couldn't understand most of it, his intuition told him that what Fang Ruitao said was absolutely true, and he immediately asked: "What you said does have some truth, but you say that some impurities are good for iron, what does this mean?"

Fang Ruitao knew that if he didn't explain it clearly today, this Capri teacher would definitely not let him go, so he had to patiently explain: "Some impurities are fused with iron, which can enhance the properties of iron in some aspects, such as steel with manganese, which can enhance toughness, effectively remove harmful sulfur in steel, make steel have higher strength and hardness, and strengthen its thermal processing ability." Adding nickel to the pen "Fun" Pavilion www.biquge.info can improve the strength of steel, while maintaining good plasticity and toughness, and can also resist corrosion and avoid rusting of steel. Fang Ruitao gave two examples of alloy steel to illustrate, because there are too many professional terms, Capri's eyes are straight, but what he doesn't know is that Fang Ruitao is also theoretical knowledge, if he is asked to identify, he doesn't know how to distinguish these ores.

"I haven't heard of any of these miscellaneous terms you mentioned, but you have something real for me to see. Capri has always been a little unresponsive to this subversive theory.

"Absolutely. Fang Ruitao said and took out the paratrooper knife and said: "This is the alloy steel knife, which is made with manganese, molybdenum, titanium, niobium, tantalum and other elements when refining, and this element is the useful impurities I said." It is precisely because of the addition of these elements that the hardness and toughness of this weapon far exceed that of ordinary steel, and even against the Demon Refining Weapon, it will not fall behind at all. ”

Fang Ruitao's words made everyone in the classroom gasp, they naturally knew the power of the magic refining weapon. Since almost every magic refining weapon is made of a solid array or a sharp array as the most basic formation, every magic refining weapon has a great advantage over ordinary weapons, and now there is an ordinary weapon, which can fight against a magic refining weapon with a solid array or a sharp array with a solid array or a sharp array based on the material alone, how is this not shocking.

This kind of weapon is not just a matter of solidity, if you can make this kind of weapon, when carving the formation on the weapon, you can omit the solid array and the sharp array.

This advantage doesn't sound like much at first glance, but the number of formations that can be engraved with magic refining weapons is limited, and once such a position is saved, one more formation can be engraved. If the Demon Wind Array was carved on it that was specifically designed to increase the combat power of other magic arrays, its combat power would be greatly enhanced, so when Fang Ruitao said how strong it was, people who knew a little about magic alchemy immediately realized its advantages.

"Can I try it with it?" Mr. Capri looked at the strangely shaped weapon over and over again, still in disbelief, and he could only ask if he could test it.

"Of course, you can try it with a magic weapon. "Once used it to fight against Gaudi's magic dagger without falling behind, Fang Ruitao has absolute confidence in it.

Teacher Kabri shook his head and said, "It's not necessary, if such a cherished weapon is against the Demon Refining Weapon, any damage will make people feel distressed, and it is enough to use it to slash ordinary weapons." With that, he borrowed a short sword from one of his students.

The people who study magic alchemy majors are all rich people, and their weapons are naturally not too bad, and this short sword is also a well-made homogeneous steel short sword, and its quality is still guaranteed. Capri shook the short sword horizontally and nodded at Fang Ruitao.

Fang Ruitao held the paratrooper knife, took a deep breath, and conveyed the true qi to the arm holding the knife. With a loud shout, the paratrooper knife in Fang Ruitao's hand slashed towards the steel short sword from top to bottom. Capri's hand shook, and in everyone's stunned gaze, the paratrooper knife actually easily cut the short sword in two, although the fracture was not completely smooth, but it could be seen that it was cut rather than torn, but the blade of the paratrooper knife did not have any gaps.

"It's such a fast sword, this is not a magic weapon. The classroom was already full of exclamations.

Capri looked at the broken sword in his hand stupidly, and after a long time, he said in an almost trembling voice: "Good sword, really a good sword, I don't know if you can sell this alloy steel formula to the school, we will pay a high price." As he spoke, he raised his head and looked at the paratrooper knife in Fang Ruitao's hand with bright eyes, as if a person who had been hungry for three days had seen the food.

Fang Ruitao scratched his head and said: "I don't know about this, this knife was not created by me, and its formula is also a secret in the family, I can't come up with the formula, and I can't create it." To avoid trouble, he could only say it mysteriously.

Capri looked up and said, "Knife, is this a new sword?"

Fang Ruitao raised the paratrooper knife and said: "Teacher, you see that it only has one side of the blade, and the other side has a thick back, which is designed to increase the force of the split, so it is not a sword, but a brand new weapon." ”

As a non-combat professional alchemist, Capri had no idea about the weapon innovation that this weapon might produce, and he just asked casually, but now he was most concerned about the formula of the alloy steel. "This weapon called the knife, is its material formula highly confidential? Capri still didn't give up.

"I'm out of the family experience, and I'm not allowed to go back until I reach the level of the war king. Besides, with my status in the family, I can't get in touch with this advanced forging technique at all, unless I reach the Battle Emperor. Fang Ruitao doesn't blush at all now to brag, he knows that his knife will be coveted by many people when he takes it out, but this knife has been used many times, and it is inevitable that it will not be remembered by those who have a heart. He took advantage of this time to desperately brag about the strength of his family, if anyone still coveted it, he had to weigh whether he could withstand the anger of the other party, and the other party was still a hidden family with unfathomable strength.

Reaching the formula that only the War Emperor can touch, it is self-evident how strong this family's strength is, and when they heard Fang Ruitao's explanation, they all gasped. Fang Ruitao didn't seem to be shocked enough, and continued: "I don't have a high status in the family, so I can't get the magic refining weapon, I can only get this half-finished knife embryo, if I can return to the family, I can learn a more advanced magic alchemy." Fang Ruitao's implication was naturally that learning magic alchemy here was just to lay a good foundation, and the real magic alchemy had to be learned back in the family.

Capri looked Fang Ruitao up and down in astonishment, in his impression, there seemed to be no hidden family that was very powerful in magic alchemy, but he also knew that the real hidden family, he couldn't know, so he didn't doubt Fang Ruitao's identity. On February 6th, the 17th district of Xianxia Road will be launched, and the game level will reach level 50 and 11200 grains will be automatically credited to the account
