Everyone stood in front of the machine, watching the pressure continue to increase, from one to ten, an ordinary saber on the market must reach at least six levels of hardness to be qualified, after all, the Rockwell test is the easiest of the four challenges.

Three...... Four...... Five...... Six......

The pressure quickly increased to six, and Huangfu Jiang secretly breathed a sigh of relief, and he was not very optimistic about the dragon thorn, thinking that Su Yuan was just playing with tickets. But if you don't even reach the passing mark, that's a shame.

Seven...... Eight......

"Huh?" Tom's face gradually became serious as the pressure continued to rise, as the technical director of a top brand, he came into contact with countless steels every day, and he knew the approximate hardness by the weight as soon as he got started.

The dragon thorn is obviously much lighter, probably because the density is not enough, even if it is handmade, it has to go through a hundred refining into steel and quenching process, usually the manual saber is heavier than the industrial flow knife.

Eight...... Nine......

As the pressure mounted, Tom walked up to the monitoring table in a few steps, staring at the flickering data, frowning and not speaking.

The tester looked at the data and asked in a low voice: "Perfectly under pressure, without the slightest exceedance, is it possible to activate level ten?"

A hint of surprise flashed in Tom's eyes, and when he looked back and saw Su Yuan's calm expression, he nodded and said, "Start!"

The tester pressed the red button, and the indicator meter instantly filled up, reaching 10 levels of pressure, 280 kg.

It may not sound too high, but the extremely sharp diamond unit area is less than 0.1 square centimeters, as if an elephant is standing on the tip of a needle, and the pressure can be imagined.

"Perfect pressure!"

Fifteen seconds later, the tester finally reported the results, the machine stopped, the data acquisition was successful, Tom looked at the graphical analysis table, and said with some excitement: "It's incredible that it can withstand the pressure perfectly!"

Huangfu Jiang was also full of surprise, and then looked at Su Yuan, who was calm and calm, and suddenly had an unfathomable feeling, could this be the level of the first place in the heavenly list?

Tom took the lead in taking back the dragon thorn, studied it carefully again for a long time, still didn't see anything special, came to Su Yuan, and said sincerely: "Mr. Su, I apologize for the rudeness just now, this saber is indeed not ordinary, how about continuing to participate in the test?"

Su Yuan nodded, he came here to pretend to be forced, Tom excitedly came to the test bench next to him, handed over the dragon thorn to the tester with his own hands, and began the wear-resistant challenge.

In the midst of the immersion, Su Yuan also slowly felt the charm of the saber: the hardness of sharpening iron like clay, the indomitable toughness, the never-wearable retention and the perfect rust resistance, as strong as the Edman alloy in Wolverine's body in X-MEN is the ultimate goal.

The wear resistance test is very complex and depends on the manual operation of the tester, which is mainly divided into two parts, namely the static retention test and the dynamic edge impact test, which aims to reflect the comprehensive performance of the tool hardness, retention, toughness and other aspects.

THE STATIC RETENTION TEST IS MAINLY BASED ON CUTTING AND CUTTING, TAKING 4-5CM OF THE CUTTING EDGE CLOSE TO THE ROOT AS THE CUTTING AREA A, AND SELECTING THREE MATERIALS THAT HAVE A SIGNIFICANT IMPACT ON THE DECLINE OF BLADE RETENTION: HEMP ROPE, CARDBOARD AND DRY WOOD AS THE CUTTING OBJECT, CUTTING THE THREE MATERIALS OF THE SAME MAGNITUDE, AND NOT STOPPING UNTIL THE RETENTION DECLINE.

FOR THE DYNAMIC EDGE IMPACT RESISTANCE TEST, THE TEST EDGE AREA SELECTS THE 4-5CM AREA OF THE FIRST HALF OF THE CUTTING EDGE AS THE B AREA, WHICH IS SEPARATED FROM THE RETENTION TEST AREA TO ENSURE THE RELATIVE FAIRNESS OF THE TEST.

Through the impact of different hardness materials on the cutting edge, the impact resistance of each steel is investigated, whether it is easy to roll or easy to chip. The materials are mainly divided into four progressive hardness materials: hard and coarse dry wood, 6061 aluminum rod, H59 brass rod and 304 stainless steel.

ALL THE TEST PROCESS IS MONITORED AND RECORDED TO ENSURE FAIRNESS AND JUSTICE, THE TESTER STARTS THE RETENTION TEST IN AREA A, 20 METERS LONG AND 15MM DIAMETER HEMP ROPE, 20 SHEETS OF 100CMX60CM CARDBOARD, 2-4CM DIAMETER OUTDOOR DRY WOOD.

Zone B impact test, hard dry wood 7.5CM diameter, 6061 aluminum rod 10mmX1m, H59 brass rod 5mmX, 304 stainless steel rod 5mmX half meter.

Finally, the score ratio is calculated according to the retention decline, and the total score is calculated once there is a subjective white line or an objective A4 paper decline.

The tester took the dragon thorn and began the test meticulously, moving quickly without the slightest hesitation or pause. One minute...... Three-minute ...... Five minutes...... Ten minutes......

The more Tom looked, the more surprised he became, knowing that seemingly ordinary hemp rope and cardboard were a huge test for the saber, and quantitative changes caused qualitative changes, once the quantity exceeded the limit, it would immediately cause a decline in sharpness, seriously affecting the efficiency of use.

But this dragon thorn ......

To say that the coolest thing is the tester, I have never felt so relaxed and smooth, so cool that I don't want to stop at all!

I don't know how long it took, but I suddenly found that all the test materials had been swept away, and I raised my head blankly, licked my lips, and asked unsatisfied: "Do you still need to continue?"

Tom took a deep breath and knew what the result would be without calculating, 10 points, full marks!

The data was collected again, and it appeared on the big screen, with a Rockwell hardness of ten points, a wear resistance test of ten points, and the dragon thorn instantly surpassed countless competitors and jumped in front of everyone at once.

"Huh, look at the big screen!"

"Dragon of Bayonet?"

"MY GOD!

Su Yuan looked at the hall and many people began to talk about it, showing a smile, this is the effect of the system requirements, what platform is more suitable for becoming famous overseas than here?

Tom picked up the dragon thorn and rushed straight to the third test point, which was also one of the most difficult of the four challenges.

The so-called bending vibration is to use ultrasonic waves of different frequencies to comprehensively test the blade, and the strength is from one to ten, and more than seven is considered a high-quality product.

It is the biggest test of steel toughness, once the computer monitors the bending deformation of the blade greater than three degrees, even if it is unqualified, the challenge fails, and the data collection is confirmed.

Because of the short length of the saber, more than three degrees of deformation or tilt will seriously affect the efficiency of use, for several top brands, bending and corrosion is the battleground, the best representative of the embodiment of scientific and technological content.
