"Bet, bet?"

"Since you are so confident, then I will work with you to make the weapon on your drawing, and then try its patience, how about it? Since you are so confident in copper wire, then this bet, you will not dare to fight, right?"

"Hit it!"

Chen Yi thought about it for a while, and still made this bet with Geng Qiu.

Your own design should be no problem, those few keys, in addition to copper wire, there is no other better material, it stands to reason that your own drawings are absolutely feasible!

Geng Qiu didn't talk nonsense: "Follow me!"

When he came to Geng Qiu's computer room, Geng Qiu began to build cast iron after dividing five by two, and asked Meng Qianji and Meng Wuyang to polish the copper wire for him.

"No, I'll do it myself!"

Chen Yi is afraid that these two people will do their hands and feet on the copper wire, and it is more reassuring to hand over the polishing work of the copper wire to himself.

Seeing through Chen Yi's thoughts, Geng Qiu did not break him, but reminded him.

"Actually, it's a very simple question, and I don't understand why you can't figure it out. If the copper wire is really useful, why doesn't the maker of Fire Dance Wind mass-produce Fire Dance Wind and Tianxuan, why is there only one of Fire Dance Wind Sleeve Arrows?"

"This ......"

If copper wire is really useful, why don't the makers of Fire Dance Wind purchase a large amount of copper wire and mass-produce Fire Dance Flow?

Indeed, the explosive power of copper wire for the fire dance wind is indeed very reluctant, but in addition to copper wire, can there be anything else that can replace it? You know, among the metals, only copper wire is the toughest!

Just as Chen Yi was thinking, Geng Qiu had already finished casting.

"You can put it together according to the drawings yourself, so as not to wait for us to do it." ”

Chen Yi also polished the copper wire and began to splic, and it didn't take long for the splicing to be completed. Not to mention, it does have the taste of fire and dance.

"You try. ”

Chen Yi loaded the arrow, and then launched it, and the sleeve arrow hit the bull's-eye steadily.

"Isn't that great?"

"Go on, the Fire Dance Wind is nine Hidden Arrows!"

Chen Yi continued to install the Hidden Arrow to fire, and the second method also burst out, but the power, how could it feel much worse than the real Fire Dance Stream?

The third shot, it was even slower.

Chen Yi was a little panicked, he installed the fourth Sleeve Arrow and pulled the trigger, but the Sleeve Arrow was not fired.

"How so?!"

Chen Yi began to pull the trigger frantically, but to no avail.

"Don't try again, the copper wire must have broken. Geng Qiu said.

Chen Yi didn't believe in evil, and dismantled the shaft sleeve, and sure enough, the copper wire inside had been completely broken. Obviously, the copper wire can't withstand the explosive power of the fire dance wind.

"This ...... Why is this happening? Copper wire is already the toughest metal......"

Geng Qiu shook his head helplessly, it was really a pity for this child to stay in Tianxuan.

Tianxuan has always taken the two major departments of demon eradication and combat as the main training objects, so Tianxuan's academy also focuses on the education of these two departments. But they don't know that the caster system is just as important!

Excellent casters are cultivators, and the weapons they cast are often hard to find!

And Tianxuan doesn't seem to care about the casting department, Qingyun Academy, and the casting department don't have a stage. Therefore, Chen Yi, a child, is so lacking in the knowledge of the casting department!

"Who told you that copper wire is the toughest metal?

"Crystal Fall Iron, what's that?"

Sure enough, Tianxuan couldn't learn the top-level knowledge of the Casting Department at all, and a talented student like Chen Yi didn't even know what Crystal Cold Iron was.

"Crystal Meteorite Cold Iron is the mineral crystals produced by extraterrestrial meteorites hitting metal ores, and these mineral crystals absorb the essence of the sun and the moon under certain conditions, and this is the toughest metal, don't you even know this?" Meng Wuyang explained for Chen Yi.

"These mineral crystals are very difficult to form, so the crystal cold iron is even more rare, it is a treasure that is hard to find, and the explosive power of the Fire Dance Wind comes from this metal!" Geng Qiu also continued to solve Chen Yi's doubts, and then, he took out the real Fire Dance Wind and disassembled it for Chen Yi to see.

"See, this is the Crystal Meteor Cold Iron, the only one that can provide such a powerful explosive power as the Fire Dancing Wind. “

"Crystal Fall Iron...... You...... Why are you telling me this?"

"Don't you know?" Geng Qiu looked at Chen Yi kindly, "Don't you know how amazing your talent in casting is?"

"I ......"

"Although you haven't solved the puzzle I assigned to you, it's impossible for anyone to solve this puzzle! Because this is the blueprint of the Fire Dance Flowing Wind! However, you did it, you don't know the Crystal Meteor Cold Iron, and you want copper wire to replace it, these are all minor problems! Do you know how much wisdom it takes to understand the design of the Fire Dance Flowing Wind? I retracted my previous words and said that Tianxuan did not have an excellent caster cultivator. Obviously, you're that very good caster-type cultivator!"

"But I'm ...... It's not a caster's ......"

Geng Qiu patted him on the shoulder and said earnestly: "In Tianxuan, the treatment of cultivators in the casting department is not good, so it is difficult to learn the top-level knowledge of the casting department. That's why you don't know Crystal Fall Cold Iron!If you want to go to the next level, just change the department, leave the combat department, transfer to the caster department, and come to study at our Hub Royal Academy!"

As soon as this remark came out, the audience was in an uproar!

"What, teacher, you're not kidding, are you?"

"That's right, teacher, no matter how good Chen Yi is, he is also a person from Tianxuan, he is a person from Qingyun Academy!"

Geng Qiu waved his hand, signaling that Meng Qianji and Meng Wuyang didn't need to say much.

"Chen Yi, I'm just telling you your talent, whether you come or not, the decision is up to you. However, I can tell you very politely that if you want to learn the most top-notch knowledge of the casting system, you will never be able to do it in Tianxuan! Tianxuan will only focus on the combat system and the demon slaying system! Moreover, if you want to enter the Royal Academy of the Hub Empire, it is not so simple, you must obtain your principal's permission to study abroad, and you must also pass the Hub Empire's study abroad exam, I think, according to your current knowledge reserve, it is very difficult to pass that exam, after all, you don't even know the crystal meteoric cold iron, and you don't know such a famous crystal metal, let alone the more obscure crystal metal. In the study abroad examination, the test questions about crystalline metals account for a very heavy proportion. ”

Chen Yi was a little at a loss, Geng Qiu, is he recruiting himself?

"If you're interested, you can check out this book. ”

Chen Yi took Geng Qiu's book.

"This is ...... ...... of the Illustrated Book of Crystalline Metals"
