"What?"

Romanov was a little stunned when he heard this, and asked with a surprised face: "Do you also have dragons in the human world?"

"That's right!" Shen Chai said nonsense without blinking, "It's just that it is the same as the era of the gods in the Magic Continent, and now it has become a legend." ”

"Oh, I can't imagine that the human world and the magic continent have similar histories!" Romanov sighed, "By the way, besides this drawing, do you have any other requirements for the weight, color, etc. of this knife?"

Shen Chai was taken aback when he heard this.

This Romanov's arrogant, stubborn and arrogant character has been taught by Shen Chai, but now when it comes to forging, he is still very rigorous!

In fact, from the moment Romanov entered this casting room, all his bad temper unconsciously subsided a lot.

"The weight of the knife?"

Shen Chai picked up the metal lump on the material rack and tossed it up and down in his hand to feel its weight, and when he tried the third piece, it felt quite suitable, so he threw it to Romanov.

"That's just the right weight!"

Shen Chai had tried it just now, and the weight of this piece of metal would not make him feel light and fluttering, nor would it be too heavy to affect the speed of swinging.

Romanov took the piece of metal thrown by Shen Chai, shook it up and down, and said with a little surprise: "Are you sure? This piece of metal is almost more than fifty catties!"

"Sure!" Shen Chai nodded, "It's refreshing to kill pigs with a heavier knife!"

The Romanovs were silent for a long time, how could a Terran magician wield such a heavy weapon?

However, the Romanov is just a foundry, and he only needs to forge according to Shen Chai's requirements, and he doesn't have to worry about the rest.

"As for the color," Shen Chai thought for a while and said, "Let's focus on black, the blade must be sharp enough, but it can't reflect in the sun, can you do this?"

The reason why Shen Chai asked for this is reasonable.

First of all, as a magician, melee combat can only be used as a secret means to give the opponent a fatal blow when he is taken by surprise, so the knife must not be too conspicuous, and even very secretive.

Secondly, this knife is used in conjunction with Shen Chai's Shadow Step, and the Shadow Step is a magic skill that shuttles through the shadows, which is characterized by being secretive, and naturally requires a dark-toned knife to cooperate, otherwise the knife will shine with cold light or something as soon as it lights up, wouldn't it expose its position!

"It can't reflect in the sun, but it has to be sharp?"

Romanov's brows furrowed when he heard this, this is really a problem!

He paced back and forth in front of the casting table, all the information about the properties of the metal scrolling through his mind at high speed, trying to find a metal that met Shen Chai's requirements.

And Shen Chai was not in a hurry, he understood that this matter was not in a hurry, and he also hoped that the Romanov could go all out to take this casting seriously, and work slowly and carefully!

Because the forged knife is what he chases!

"There it is!"

Romanoff suddenly let out a loud cry and began to rummage through boxes and cabinets to find something.

After a clanging of bells, Romanov pulled out a black lump from the innermost part of the material cabinet.

"What is this black and non-slippery thing?" Shen Chai asked suspiciously, "Are you sure it's not a Demon Beast poop fossil?"

"You kid don't know how to read goods!" Romanov glanced at Shen Chai, put the black thing into the water tank and soaked it, and then began to clean it repeatedly, "This is the tungsten iron core that my father picked up from the tungsten mine!"

"Tungsten core?" Shen Chai repeated, "Is it precious?"

"It's not precious, but it's very rare!" Romanov took out the cleaned tungsten core and held it in the palm of his hand, "The probability of the formation of this tungsten core is extremely low, and it is the probability that tungsten ore can be bred after thousands of years in a high temperature and humid environment!"

"Thousands of years!" Shen Chai's eyes suddenly lit up when he heard this, "It took thousands of years to conceive, and it is not precious?"

Romanov smiled bitterly and said: "Although the output is difficult, it is really not precious. Because it's too hard, it's laborious to forge, and it can't conduct magical elements on its own, it ...... It can be said to be a rare piece of scrap iron!"

Nima! Shen Chai's face turned black when he heard this, scrap iron? You Romanov used a piece of scrap iron to forge a knife for me?

Seeing that Shen Chai's face was not good, Romanov immediately explained: "According to the usual magic guide standards, this tungsten iron core is indeed a piece of scrap iron, but it meets your requirements!"

"Really?" Shen asked suspiciously, "What do you say?"

"It's because the tungsten iron core is too hard, so it is strong and sharp enough to be forged, and this thing really doesn't absorb or reflect light at all, even if the sunlight is strong, it's still black!"

Romanov said happily: "So, it is a match made in heaven with your request!"

"Wait!" Shen Chai stretched out his hand to interrupt Romanov's blowing, because he had found a very important problem!

"You just said that this tungsten iron heart does not conduct magic power, since it does not conduct magic power, how to make a magic guide?" Shen Chai said with a suspicious face, "I don't read much, don't fool me!"

"Don't worry, I have a hunch that this knife will be my pinnacle!"

Romanov rubbed his big nose triumphantly: "You just see, watch my Romanov use exquisite casting skills to complete a masterful work!"

With that, Romanov lifted the cold iron lid on the casting table with a round of arms.

With a "boom", a surging tongue of fire suddenly erupted, and the temperature in the casting room rose sharply.

The Romanov then clamped the tungsten core with a long-handled iron clamp and placed it on the magma flame.

After about ten minutes, the tungsten iron core had become completely translucent red in the blazing magma flames!

Romanov placed the tungsten iron core on the forging table, held the iron clamp with his left hand, picked up the heavy eight-sided plum blossom casting hammer with his right hand, and smashed it towards the tungsten iron core.

"Bell!"

There was a sound of fine iron handing over, and brilliant sparks scattered in all directions.

"Bell, bell!"

The casting hammer in Romanov's hand was constantly striking on the already burned red iron core, sometimes heavy and sometimes light, sometimes fast and sometimes slow, and the rhythmic percussion sound merged into a cheerful music.

Shen Chai observed carefully and found that every time Romanov struck, it smashed right in the center of the iron tungsten core.

After about a hundred strikes, the tungsten core was smashed in two, and there was almost no difference in weight between the two tungsten cores!
