v2 Chapter 73： Song Ming stunned by listening (one/four)

Immediately afterwards, the honest middle-aged man solemnly explained: "Mr. Song Ming, let me introduce to you the short knife I just built."

"For the blade material, I first use an extreme temperature heater to preheat it at 800-850°C to avoid thermal stress."

"Then, I quickly heated the material to a quenching temperature of 1190 to 1290°C, and then cooled it with an inflatable body."

"At last……"

"After heavy processing, the blade material is absolutely secondary quality, containing carbide-forming elements such as tungsten, molybdenum, chromium, vanadium, and cobalt, and the total amount of alloying elements is about 10-25%."

"Even in the case of high heat generated by high-speed cutting, it can still maintain extremely high hardness."

"I have a built-in electric shock device in the knife handle. As long as the knife is in contact with the skin, body or blood, the electric shock device will be turned on immediately, releasing a high voltage current exceeding 2000V in a short time, directly impacting the opponent's body..."

…………

After speaking, the honest middle-aged man looked at the chief examiner Song Ming earnestly, waiting for Song Ming's evaluation.

"Wait a moment."

Holding the short knife, Baibeard Song Ming said lightly.

Then, under the scorching gaze of everyone, Song Ming walked slowly into the appraisal room with this short knife in his hand.

There is no doubt that the next Song Ming will use various instruments to test the hardness of the blade, the effect of electric shock, etc., to determine whether this short knife is eligible to be classified as a secondary quality.

"I heard that Mr. Song Ming's appraisal has always been extremely harsh!"

"Yeah! Mr. Song Ming is a third-level martial arts equipment engineer, and his general second-level quality is not in his eyes."

"Ah? If that's the case, wouldn't I be out of the picture again? In the previous assessments, I couldn't even handle ordinary appraisers. This time it is Mr. Song Ming..."

…………

With Song Ming's departure, the many examiners in the room whispered to each other, and all of them were a little nervous.

Especially the honest middle-aged man who was the first to accept the appraisal, he was fidgeting, his brows furrowed, and his palms were sweating.

Only Chen Xuan, with a self-confident expression, always showed exceptional confidence and calmness.

Even more, he took advantage of this gap to enter the virtual universe and engage in a matchmaking battle of the same level.

Of course, with Chen Xuan's current strength, in a matching match of the same level, it is definitely difficult to lose!

Six extreme powers, shadowless daggers, void steps... these superimposed, give him an unparalleled huge advantage in the martial artist-level physical quality and life level!

Even among the highest civilizations, there are not many people who can compare with him!

In Chen Xuan's view, unless he encounters a life with a special talent like the pterosaur last time, he will not be defeated at all if he is matched at the same level!

…………

In this way, 8 minutes passed in a flash, and Song Ming returned to the sight of everyone.

"Your knife is very good in terms of materials, and it has indeed reached the second-level quality."

After some plain praise, Song Ming handed the short knife back to the simple middle-aged man, then shook his head, and said, "However, your electric shock equipment is too simple in design, and it is easy to hurt the user. It really doesn't meet the second-level quality standards."

"So, on the whole, this short knife of yours, for the time being, cannot reach the second-level quality!"

"You can leave now!"

…………

After listening to Song Ming’s evaluation, the honest middle-aged man suddenly felt cold, and then without arguing, he left the laboratory with a lonely expression and disappeared into everyone’s sight...

There is no doubt that the honest middle-aged man himself knows that the use of his electric shock equipment is very "simplistic", and there is not much technology to speak of.

With such a judgment result, he was convinced!

"Next, Liu Ming."

"Hello, Mr. Song Ming, this is the Taiyun heavy axe that I built..."

…………

In this way, one by one, the chief examiner, Mr. Song Ming, continuously identified the weapons built by everyone, and gave a very fair judgment on all of them.

However, since Mr. Song Ming is a third-level martial arts equipment division, his judgment standards will undoubtedly be slightly higher than those of past appraisers.

Because of this, more than 20 people passed in a row, and the "work" of only one person barely entered the eyes of Song Ming, giving a judgment of second-level quality.

Everyone else, without exception, was eliminated!

At this moment, in the entire experiment, only Chen Xuan was left as the last examiner.

"Okay, you are the only one left."

Looking at Chen Xuan, Song Ming said casually: "Young man, come with your work."

"Ok."

Chen Xuan nodded immediately, and immediately handed the pair of gloves he had made to Song Ming's hands, and carefully explained: "Mr. Song, my pair of gloves is divided into two completely different materials, inside and outside."

"Inside, the polymerized mulberry silk material is used, which is soft and smooth, waterproof and protected from light..."

"Externally, I use a special material combined with high molecular weight polyethylene and carbon fiber This material has low density, high specific performance, no creep, and can withstand ultra-high temperatures in a non-oxidizing environment. Corrosion resistance, X-ray permeability, and electromagnetic shielding are all excellent..."

"At the same time, I have built-in external materials that can temporarily paralyze the nerves..."

…………

After listening to Chen Xuan's words, Song Ming frowned suddenly, behaving very surprised, and then repeatedly asked: "How did you get this carbon fiber material?"

Undoubtedly, Song Ming, the third-level martial arts equipment master of the human world, did not understand the material Chen Xuan said...

In other words, what Chen Xuan said just now made Song Ming bewildered!

Of course, this is also a very normal phenomenon!

After all, Chen Xuan was trained by Ruth!

Who is Ruth? That was the seventh-level martial arts equipment division in the supreme civilization!

In the process of training Chen Xuan, what she tells is bound to be the research results of the Supreme Civilization!

Under such circumstances, it is entirely reasonable for Chen Xuan to come up with "new things" that Song Ming has never heard of...

"Uh……"

Seeing Song Ming reacting in this way, Chen Xuan had no choice but to explain to him: "It's like this, this carbon fiber material, I just used a fiber processor to stack organic fibers such as flake graphite crystallites along the fiber axis. It is a microcrystalline graphite material obtained by carbonization and graphitization."

"The quality of this material is extremely low, but its strength is higher than that of steel, and it has corrosion resistance and high modulus characteristics."

"It can be said that it not only has the inherent characteristics of carbon materials, but also has the soft and processability of textile fibers... It is absolutely great to use such materials to make second-class gloves!"
