As soon as Matur's voice fell, the ground silently parted, and metal platforms emerged from the ground, each with a different place.

"The thing to be tested is on the biggest platform, codenamed 'Grammer'."

"Are you sure this thing will blow up?" Li Su picked up the equipment on the platform and looked at it. It looks like an ordinary Japanese sword, with no blade, and I don't know what kind of metal it is. Li Su used the field to test it, and found that this simple steel bar actually used nanotechnology, and it was not at all like the traditional sword with countless "eyes". Is there a special decisive weapon for Natsumi? How did the armament department know her abilities in advance?

I tried to swing it, and it was unexpectedly good. The weight of the long knife is just right, and the center of gravity is also appropriate, and it looks like an extension of an arm when wielded. I didn't expect this group of bomb-addicted maniacs to have such a high attainment in cold weapons.

"Not now." Matur said. "Next, put the second part on your back and attach the cable on the side to the end of the handle."

Li Su carried the backpack-like thing on his back as Matur said, and sure enough, he found a cable on the side, pulled it out and connected it to the handle of the knife.

"And then? Do you press this button? ”

"Yes, don't hold the knife too tightly."

Pressing the button, Li Su felt a vibration go up along his arm, but the impact was not great, and what surprised him the most was that the blade gradually glowed with molten gold, like a mythical weapon in various legends.

"Let's try attacking Target One." Matur said.

"It's so concise and straightforward." Li Su held the knife with both hands, and the tip of the knife pointed forward, pointing to the No. 1 target. The humanoid target appears to be wooden, with a deep red, smooth surface with flowing clouds. The surface is engraved with a large Arabic numeral 1.

Li Su stepped forward and swung his knife diagonally, and the long knife easily cut off the target, as if cutting through the air. Li Su stretched out his hand to touch the cross-section of the target, which was as smooth as a mirror. "Has the Armament Department now degenerated into chopping wood to verify the effect? Are you responsible for providing logging equipment? ”

"Of course not." Researcher Matur's voice was full of contempt. "Usually the main objects on YouTube are plywood, particleboard and ordinary wood, and we use rosewood, one of the hardest woods. It's nice to cut a lot of toys that you can buy in cold steel and leave a mark. ”

"Rosewood...... I think this stuff isn't cheap, right? It's still such a big piece......"

"It's all for great science!"

"You make so much sense that I can't even refute it."

"Now try Target 2."

"Hmm." Li Su slashed at the No. 2 target, slashing in two.

"He's a good boy, isn't he? Don't worry too much. The vice principal said to the figure by the window as he shook the beer can in his hand.

I don't know when the principal and vice principal appeared in this small control room, the two of them occupy half of the control room, and the other half of the members who are directing the experiment are very distinct.

"Do you know his details?" Ange raised an eyebrow.

"No, you can't find it, how can I find it?" The Vice Chancellor drank the beer from the can.

"Then why are you so reassuring of him? It's the first time you've trusted a stranger so much. Ange asked.

"Actually, I trusted those women when I was with them in the past, but you don't know."

"Get down to business."

"Okay, okay." The Vice Chancellor stretched as he placed the empty beer can on the console to the side. "Because of the eyes."

"Eyes? I didn't expect you to have this ability in the attic every day. ”

"Otherwise, how would I have known what those women liked...... Ange, if you were a spy, what would you think of your infiltration target? ”

Ange was silent for a moment, "Danger, fear, can't stay long. ”

"But he doesn't have any of that in his eyes, does he?"

"It's also possible that he's good at disguise."

"Even so, there are some things that can't be disguised, such as trust." The vice-principal shook his finger. "I don't know why, Li Su has an inexplicable trust in the Kassel Academy, this kind of thing can't be disguised. You can fake your identity and you can disguise your expressions, but you can't disguise them with countless micro-movements, because many times you don't know these things yourself. And don't worry too much, since my alchemy equipment can weaken the 'precepts', it can also multiply and strengthen the 'precepts'. Even if he wanted to use a 'candle dragon' level spirit here, I could interrupt it. ”

"Hmm." Ange was noncommittal.

"I kind of know how this thing works." Li Su stroked the No. 5 target that had just been cut off by him, and it didn't last long. This thing is made of carbon-titanium alloy, and it shouldn't be so fragile. "High-frequency cutting?"

"That's right, that's smart, No. 1!" Matur praised. "Because of the uneven characteristics of traditional materials, as long as the high-frequency vibration of thousands of hertz is added to the material, the uneven vibration in these places can quickly accumulate to achieve fatigue, and the cutting effect of the weapon body is added to achieve cutting. The principle is not difficult, but in the process of practical application, we have encountered many problems, such as the impact on the holder, and we have not been able to completely block the vibration. and the test of the material of the blade. Conventional materials break before cutting, so we use nanotechnology to ensure the strength of the blade. ”

"It sounds like a hard job, can you call me a number? It feels weird. Li Su crossed the long knife and carefully observed the surface of its golden light.

"Alright, let's start the last test, test subject!" Researcher Matur's voice was full of encouragement.

"I always feel that if I continue to tear it with you, the name will become more and more weird......" Li Su flipped his wrist and slowly drew a semicircle with the long knife facing outward, the sword was backwards, and his hands were placed on his waist. After taking a deep breath, he jumped up and slashed with force while shouting "Excalibur!!" ”

The last target was unexpectedly hard, and there was a vague feeling that it couldn't be cut in, and Li Su probably guessed the reason.

"Damn, do you need to play such a thing as contradicting yourself?" Li Su yelled at the observation window.

"Don't panic! Open afterburner! The button is three-stage, press it one more section! Matur's voice came at the right time.

Li Su pressed the button again, but before he could use his strength to cut off the target, there was a terrifying heat behind the target. Knowing that something was wrong, he directly ripped off the cable and threw the energy group far away.

Before it hit the ground, the energy group exploded in mid-air, and the light and flames spread wantonly in all directions. The dustless land was activated, the flames and heat flowed along a transparent 'boundary' and could not invade the semicircle centered on Li Su, he held the knife and looked at the deadly and beautiful light flames around him, feeling like witnessing God cast the sword of fire that destroyed the world.

The explosion soon ended, the entrance to the test site opened, and a group of men in biochemical suits rushed in with various equipment and began to extinguish the fire.

A man in a biochemical suit grabbed Li Su's shoulder and motioned to follow him, and Li Su saw the face clearly through the huge mask, Matur.

Following him out of the test ground, Matur took off his helmet with a serious expression. "There's something I want to criticize you, classmate Li Su."

"What? Didn't you tell me to do afterburner? Li Su was a little confused.

"No, you should be shouting 'Gram' instead of 'Excalibur'."

"Am I here to focus on? Shouldn't you care about me first? ”

"What are you afraid of in the dustless land? I also said that there is a possibility of an explosion. Researcher Matur shrugged.

"But you still have to do it, don't you?"

"We hate this kind of superficial work, and we can only guarantee that if you give your life to science, we will always remember you."
