"Boom!"

A violent explosion shattered the silence of the night sky, making the entire roof of the building feel as if it shook violently.

"It's so powerful, it's good!"

Ai Science pushed the thick black-rimmed glasses, looked at the scene in front of him and nodded: the center of the two-centimeter-thick pavement brick underneath had been blown out of a pit more than 1 centimeter deep, and the cracks stretched out like a spider's web, making the whole of this poor yellow brick a thing of the past, if anyone wanted to pick it up, it would probably only be torn under gravity, and the only remaining bottom that still connected the fragments, and the internal injuries that had been shattered and cracked all over the place.

Placed around the yellow bricks, the bricks used to test the power of the shock wave were not so miserable, but the surface of each piece appeared as if it had been cut by a knife qi, and one brick was even more unstable and was directly knocked to the ground with a "bang".

"Go downstairs, otherwise someone will come up and see someone call the police later." Ida said, his eyebrows were full of excitement that could not be hidden.

"This is only half a gram of nitrotetrazolium copper ammonium, if you add some more material, the power is even greater, if you double it, I'm afraid you can blow up the heads of those bastards in one fell swoop! The kind that can't be found! He said in the elevator to the final balance and Ai Science, who had come up to watch the test.

"It's more than enough. Even, it doesn't need to be so big, if you want to kill someone, another 50 to 60 percent reduction is enough. Ai Science's words reversed again, "Besides, I don't plan to use this thing to kill people directly." Power alone can't achieve the result we want, remember what we said at the meeting, you don't need anyone else to fight head-on, you can clean up that group of gangsters by yourself. We can't reveal our superpowers yet, and we need to disguise them as accidents like in the movie "The Mechanic". ”

"Then it's up to you." Ida said.

"The most important thing is Zhao Cheng's, that kid hasn't moved for so many days, I really doubt if he is slipping to play games." Zhong Heng followed, "Doctor, how are your results these days, whether it is a mule or a horse, take it out and give us a yo." ”

Ai Science: The theory and mathematical model speculation are almost done, and the mechanical parts and some complete equipment have also been built, but there are still some places that are still close, give me half a day to have results, and you still need to do some cooperation during this period. ”

"Say it." The two said in unison.

"Lao Jing, can you make the explosive device a little smaller, and it is better to control the amount of nitrotetrazolium copper ammonium, the amount of that blue powder to be less than 0.1 gram, and not even the detonation device should not exceed 5 grams, is it okay?"

"It's not a big problem technically, but I need you to cooperate with the manufacture of a miniature electronic detonator ignition device, a bioelectric connection device, a signal receiving device, and Xiaocheng needs to provide me with a chip for a miniature control initiator." Ida made a series of requests.

"That's fine. Ants, you also have work to do. The doctor looked at the final balance again, "You have devoured other template fragments like me, don't you have a toxicity enhancement ability, after you go back, first find a big worker ant of your yellow lynx ant, upgrade to the full level and show it to me, in addition, I have run out of evolution fragments, you give me another 2000 points." ”

"Huh?! I gave you fifteen thousand before, shouldn't you have more than 20,000 if you count you, so fast?! Zhong Heng was surprised, and sighed in his heart that he either squandered his hard-earned money or was not distressed.

"Don't talk nonsense, don't say two thousand with your ability, it won't take a week to earn back twenty thousand. Today I bought you a post-600 paver ant and a bunch of test tubes on the Internet, and after you go back, you will divide them and let the old well be sprinkled, and it will be back in a few hours. Al Science said.

"Okay, anyway, it's just a plan, I'll listen to you." Final Heng was helpless.

……

I didn't take a bath in the mountains for several days, didn't sleep well, and last night I cooperated with Ai Science to do research to get one or two points, leaving a sentence "Don't leave my 100-meter range, the sluggish state will not be invalid" After finally Heng washed away the stench on his body with the rain, and climbed into the bed in the air-conditioned room that he had not seen for a long time...... Well, well, it was a bunk, and in any case he slept comfortably and did not get up until noon the next day.

Overhead, on the double Simmons big bed that originally belonged to Zhao Cheng's parents, Jing Tian was still playing chess with Zhou Gong, snoring like thunder. Walking out of the door, Zhao Cheng's door was closed as always, and in the living room, Ai Science was holding a steamed bun in his left hand and nibbling on it, while the manipulator on his right was fiddling with an insect-shaped robot more than one meter long, more than half a meter wide, and nearly 30 centimeters high. Beside him, TX was typing on his laptop keyboard as usual, doing secretarial work.

"Morning, how's the research going?" Final Heng asked.

"It's early, it's noon." For the first time, Ai Science, who was in a state of scientific research, actually showed a smile.

What can make this kind of scientific research madman laugh, don't even think about it, it must be that the scientific research results are about to come out.

"It's finished." After fiddling with it for three or five minutes, Ai Science put away the metal tentacles for 3D printing in his right hand, and said excitedly, "Call Lao Jing and Xiao Cheng up, and look at the results of our struggle these days!" ”

Ida and Zhongheng sat side by side on the sofa, like obedient elementary school students, and Ai Ke was like a stern teacher, holding a whip in his hand, pointing to the LCD TV screen that had been connected to the computer.

"First of all, I'm going to show you two of the most rudimentary killer features of our operation, on which all the other secret weapons have been developed. Here, I would like to thank you for your help, this is a miracle in the history of the development of semi-biological robots, without your help I would never have been able to create this kind of semi-insect robot that I am afraid the world will never find more advanced than it! Ai Science said solemnly as usual in his academic presentation, "And Lao Jing, thank you for your support in explosives." ”

It's a pity that Zhao Cheng, an "Internet addicted teenager", didn't know what was going on today, his butt was like glue and he couldn't sit on the chair, and he blamed him for deadlifting, "I'm getting to the key place, can you afford to pay for the mistake", otherwise the living room will definitely echo the loud applause of this middle school disease.

"Long story short, this is our No. 1 killer feature, the self-destruct bee!"

The slides switch on the screen, and a row of golden-ringed wasps standing neatly in transparent tape boxes appears, and Ai Science holds the real object in his hand.

These golden-ringed wasps are parked parallel to each other, like fighter planes ready to take off, except that their eyes are dull due to the control of the final balance, and they are also different from their peers in that their black-brown chest and dorsal plate have a hint of modern technology.

There are two types of golden-ringed wasps in the box, one is a blue object with a small fingernail on its back, and what appears to be a bead-like object wrapped in plastic wrap. The other is carrying two bags the size of mung beans, orange on the front and blue on the back. The two were joined together, orange in front and blue in the back, and the outer one was wrapped in a translucent hollow cylindrical cannon-like membrane that was narrow in front and wide in the back.

A thin wire is attached to a half-centimeter-square plastic cube hanging below their abdomen, and a green lamp the size of a needle is lit on the left side of the cube.

"There's nothing special about this thing, the only thing it does is - an explosion, which is remotely activated by a computer through an electronic signal, and you can think of it as a miniature missile." "At that time, as long as you use your ability to control these bees to get close to those gangsters, you can control the wasps to bite down a special switch installed under the head with their big jaws, and the bomb will explode. As long as it is pasted by the self-detonation bee, the tempered glass can be blown through by the nitrotetrazolium copper ammonium powder it holds, and if a person's head is hit like this, he will definitely not be able to suffer the damage of a sniper headshot in an instant! ”

"Of course, if those gangsters want to take out the last insecticide to attack again, it doesn't matter, because we have two kinds of bees, one is carrying a blue single explosive pack, pursuing pure power, and the other is not so powerful, but it also has a long-range attack ability while self-detonating."

The doctor gestured to the golden-ringed wasp carrying a cannon-barrel-like object on its back.

"After the explosion of the blue nitrotetrazolium copper ammonium powder in the back, the miniature shells wrapped in special corrosion-resistant carbon fiber in front will be launched, and the range can reach tens of meters, and if it is at a close distance of five meters, it can be called a hundred shots." He excitedly continued, "The shells are filled with corrosive acid that can deal massive damage, thanks to another of our heroes......"

The slide switches, and Ai Science puts down the box containing the self-destruct bee and picks up another transparent box containing five large yellow worker ants.

"Acid Ants!"

These yellow ants were all raised to the limit by the final balance's use of "Toxicity Enhancement", and each one cost 1,500 evolution fragments to create. Their color has changed, their slender legs have turned pitch black, their beautiful bodies have changed from a shiny orange-yellow to a disgusting greenish-yellow when they look at them, and especially the tail filled with formic acid has become a dark green like a witch's poison.

The toxicity of the Stinger Squad has been increased from ordinary bee venom to a bloody poison, and the formic acid of the yellow ants that can be called "corrosive" has been raised from a slight acid that has to be slowly ground to a strong acid comparable to concentrated sulfuric acid.

A video shows a yellow ant cocking its butt and aiming its sour mist spout at a barley worm in front of it, a four- to five-centimeter-long beetle larva that resembles an enlarged maggot and is mostly used for live feed.

The barley worm was contaminated with acid mist, and the helpless exoskeleton of the ants, which was originally comparable to a soft hedgehog armor, dissolved directly, and struggled a few times before moving until its corpse completely neutralized the thick acid mist and turned into a black spongy, jelly-like object similar to the "concentrated sulfuric acid poured into sucrose experiment".

Although the acid released by the upgraded yellow ant is extremely corrosive, it is still rare to cause fatal damage to people - no way, the amount is too small, but it is different with the "cannon" carried by the self-detonating bee.

The explosion of nitrotetrazolium copper ammonium was extremely powerful, and even the barrel made of the blast shield material that Ai Science specially redeemed from the mall could not stop its explosion - there was no way, first, because the mass was too thin, and second, it was too close.

As soon as the barrel explodes, it will blow up, but it doesn't matter, it is meant to be a one-time shot, as long as it can blast out the miniature shell made of military explosion-proof fibers in front. Although the cannonball can withstand the close-range explosion of high explosives without shattering immediately, it will also disintegrate in the middle of the flight, but this is the effect that everyone wants - imagine what it would be like to be pierced deep into the subcutaneous tissue by this dummmy bullet and a terrible fragment of high-temperature acid?!

After Ai Science's calculations, a dozen or so cannons hitting a person's head may be able to achieve the disfiguring effect of being splashed with concentrated sulfuric acid, and 30 to 50 hits can kill a person, if 400 of these self-detonation bees explode at the same time at a dozen gangsters five meters away, the acid etching droplets that burst out like scattered bombs can instantly make them all immortal and disabled.

"These are just the two most basic weapons, and the really terrifying ones are still ......"

Before the word "back" could be spoken, an excited scream poured cold water on Ai Science, who was on the rise:

"Great, I made it, I made it!"

Zhao Cheng excitedly kicked open the door and rushed out, followed by a helpless face, as if to say "I don't know him" like a two-dimensional animation walked out, and was reflected in the air by the holographic projection of Banyu Mikoto.
