Hong Fan nodded seriously.

In his previous life, he was an engineer and knew a lot about materials science.

The so-called "thousands of irrigations", which is folding, is carburizing.

Livestock urine is quenched and cooled quickly, which is convenient for the blade steel to form martensite, increasing strength and hardness; Livestock fat is cooled slowly when quenched, which can ensure the steel toughness of the knife body.

"My Cui family has passed down the mountain recipe, paying attention to the evenness and stability of the strength explosion, which is the knife of a hundred times for us, which is equivalent to a thousand times for ordinary craftsmen."

Chu Deshui said and took out a horizontal knife wrapped in plain cloth and put it on the table with both hands.

"But it will only be able to make thousands of irrigations, and the highest can only go to the first-class master to make some weapons that do not enter the stream."

"If you want to be included in the four products, it is far from enough."

He unraveled the white cloth, revealing the horizontal knife within.

The blade is 80 centimeters long, with a ring head at the end of the handle, and a half-foot-long red brocade tied to it.

The surface of the knife is shiny, but the blade is dull.

"This knife is made of thousands of tough steel as the body, dark iron as the blade, and then burned the blade through a special technique, which is a masterpiece of Chu's life."

"It should be considered medium in the fourth grade."

There was pride in Chu Deshui's tone.

Hong Fan took the horizontal knife, and sure enough, it was comfortable to hold, and the center of gravity was just right.

Cui Yutang took a pig iron bar for testing the knife, and he cut it in two with a casual chop.

"Please also ask Gongzi Hong to give an inscription for this knife!"

Seeing that Hong Fan couldn't put it down, Chu Deshui surrendered his hand and asked.

"Shouldn't these be decided by Master Chu?"

Hong Fan asked rhetorically.

"Don't shirk the virtuous nephew."

Second Master Cui said with a smile.

"Lao Chu has played a lot of fourth-grade blades in his life, but in the end he is not very famous."

"After all, since ancient times, the world's famous swords have been named after the sword bearer, not the sword caster."

"Like the top of the Tianjiao list, Gu Yixin uses nothing more than a rusty gun picked up on the ancient battlefield, but now who dares to say that gun is not a famous gun?"

Chu Deshui nodded again and again when he heard this.

"That's exactly what happened."

He agreed.

"In the future, Hong Gongzi will be famous all over the world, or because of this knife, Chu Deshui will also be able to leave a place in history."

When it comes to this, Hong Fan can't shirk it.

He casually flattened the blade of his blade, and the mirror-like surface of the blade was recognizable, as if the snow outside the window had been plated on the steel.

Hong Fan inexplicably thought of Taishan when he was hunting.

The wind and snow rolled down the heavens, vast and reckless, covering the lofty mountains, but for a moment.

"Let's call this knife 'White Calamity.'"

Hong Fan said softly.

"As for the inscription, it will be determined that the four characters 'Xiongqi is killed'."

Chu Deshui was stunned when he heard this.

"What, isn't it good?"

Hong Fan wondered.

"It's not bad, it's too good......"

Chu Deshui smiled bitterly.

"The name of the knife is white, and the inscription is heroic; This feels like it has to be placed on the first and second grade of the real divine soldiers. ”

"My knife is also a fourth grade, and some of them can't hold up the name."

He blushed as he spoke.

But Hong Fan just laughed when he heard this.

"The second master just said something, and he agrees with it - since ancient times, the world's famous swords are all named after the sword wielder."

"If someone criticizes this knife for not being worthy of its name, it will be my fault, what is the blame for Master Chu?"

As soon as these words came out, Chu Deshui didn't say a word, took back the horizontal knife, and carved the knife inscription directly.

······

Three days later, December 22.

Asahi-in.

Hong Fan slashed the straw mat flying up with a white disaster volley.

The horizontal knife was returned to the sheath, swept and fell on the snow, and broke into four pieces.

He redoubled his hard training during this time, and intermittently broke through the nine major acupoints.

The forty-five acupuncture points of the Zuyang Ming Stomach Meridian have been penetrated in total, and a total of 13 have been penetrated.

In the battle of Hongduo Mountain, Hong Fan's credit was only after Hong Jian.

However, since the latter has been famous for a long time and is the number one master in Jinhai, it is the former who has gained the most in fame and fortune.

When he first returned to Jinhai City, even if Hong Fan was a man and a mature person, he would inevitably be fluttering in flattery.

After the conversation with Wen Zhongguan, the possible identity of the Xiao family behind the scenes has brought him enough pressure.

knows the appearance of the two, knows their malice against themselves, and knows that they are hiding in the Li family......

In order not to startle the snake, and in order to avoid exposing the existence of the Dragon Soul Tree, Hong Fan could not tell anyone about these news.

Even if Hong Jian and Hong Li.

So he went to Cui's house to buy a piao knife.

So he redoubled his efforts.

[A dragon soul fruit can almost boost the cultivation of close to two serious paths, and if it is used at a critical moment, it also has a special effect of repairing internal and external injuries. 】

Hong Fannei looked at the swaying glorious golden tree and calculated.

[From the qualitative change of combat power, I am still three serious and one strange scripture. 】

[Counting the Dragon Soul Fruit, it will take about four to five months. 】

He made up his mind, and went to the locked cabinet in the house to take out some of the papers, used Bai Disaster as a paperweight, and spread them out on the table in a row of three.

On the top of the white paper, three lines of simplified Chinese characters are written in a charcoal pen.

"Feasibility Study on Enhancing the Killing Performance of Sand Fog";

"Feasibility Study on Additional Power of Sand Gliding Wing";

"Further Exploration of the Combination of Yanliujin and the Sand World".

Under the article "Sand and Mist Killing Performance", there are many things written about the rules.

It includes the true element cost of the unit sand flow at different distances, the accuracy and strength limits, and a predetermined name for the killing method - Sand Mayfly.

In the blank space, Hong Fan crossed the carbon pen to open up a new experiment record column.

The true yuan floated, and the unmanned courtyard was soon shrouded in sand fog with a radius of more than ten meters.

The lethal criteria are simple, but they are intricate in practice – condense loose sand fog into a stream of sand in a snap of a finger and dig an inch through the frozen ground in a breath.

This is the most basic requirement, after all, the martial artist is not the two wolf greens that Jiang Youcai once raised.

They don't have chains around their necks, not only hands, but also martial arts.

A few minutes later, a round of testing ended.

Even after digesting all the progress made in the Battle of Red Stack Mountain, the sand mayfly's lethality limit was still only three meters radius.

It's three times stronger than the one meter when he first suffocated Wolf Qing, but it's still within the range of hand-to-hand combat.

"For this hand to have a real tactical position, the attack range must be at least five meters."

Hong Fan frowned and muttered to himself.

"According to the degree of progress in the Penetrating Realm, I have to go to the Chaos Realm to do it."

He drew conclusions and recorded them truthfully, but he was not discouraged.

The second round of tests was about the powered glider.

This is a hole card that is in no way weaker than that of the sand mayfly.

Flying is the yearning of human beings, and it represents absolute initiative in battle.

According to Hong Fan's understanding, no matter what martial arts the Great Chinese people practice, they must reach the Yuan Magnetic Realm before they can counteract gravity and fly freely.

The only exception is the Feng family's "Tiangang Divine Wind Sutra", which can glide against the wind for a long time in the innate realm.

Of course, there are thousands of life stars, and there are various abilities.

Among them, there must be more who can fly in front of the metamagnet.

PS: These chapters are transitions, and the pace will be a little slower.
