"Can you take a tour of your lab?" I asked Professor Shen.

"Of course, please follow me."

Haoyue and I followed Professor Shen down to the second floor of the elevator, we thought it was here, but it wasn't, the second basement floor here looked like a miniature version of the subway station, Professor Shen invited us to take a "subway" car - in fact, it was a locomotive, there was no carriage, an electric rail car, and there were radiating yellow and black warning signs in the car.

It took about five minutes for the car to arrive at the station, during which I turned several corners and passed through a few gates, and the speed was not very fast, and I felt that the corresponding above-ground location here should be about two kilometers away from the teaching building of the School of Science.

"Why is it that you walk sideways, can't you just go up and down?" When I got out of the carriage, I asked Professor Shen that this is also a mini station.

"If the shaft is not safe and diagonally oriented, multiple gates can be set up." Professor Shen explained.

"What's the depth of here?" I asked, and when I came, it felt like I was going downhill.

"120 meters underground, absolutely safe." Professor Shen smiled and led us to an iron door, and waved his hand at the camera above, and an iron plate on the door sank, and a small screen appeared, in which there was a beautiful woman wearing black-rimmed glasses, chestnut hair, and looking a little cold.

"Second uncle, who are they?" The beauty asked.

It seems that it is the niece that Professor Shen just said.

"The Great Commander of Wu Yifan, who I told you before, and the Immortals." Professor Shen pointed to us and introduced, I smiled and waved my hand to the video, but his niece was very indifferent and didn't react, just raised his hand and pressed a button, the small screen retracted, and the iron plate came up to block it, click, and the door opened.

Inside is a bright corridor with diamond-shaped strips up and down, left and right, a bit like a science fiction movie.

"Isn't there anyone guarding here?" I asked, along the way, there were many levels, but I didn't see anyone.

"We're a weapons lab, high-tech, we don't use much manpower." Professor Shen said with a smile.

“…… What do you mean? "I didn't understand, I was only a freshman in high school, and I knew a lot about high-tech.

Professor Shen smiled but didn't say anything, and after we walked out of a distance, he stopped, pressed the invisible switch on the wall, hum, after a burst of electric sound, I felt that my back became hot, and when I looked back, I was in the corridor, and there were a lot of red lines in the corridor I passed just now, which sealed the corridor space.

"I've seen this in the movies," I said excitedly, "is it the kind that cuts people to death as soon as they pass by?" ”

"Almost, this is shaped infrared, originally these lines are invisible, for vigilance, or to show the leaders who come to visit, they will deliberately make a red effect."

"I want to try." Haoyue stretched out her hand and was about to touch the red line.

"Oh, no! Dangerous! Professor Shen wanted to stop it, but it was too late, Haoyue's left hand was cut by a red line, except for the thumb, the other four fingers were cut off in an instant, and in the process of falling down, they touched other red lines, and they were cut twice and three times, and when they finally landed, they had become a pile of broken pieces similar to ham sausages!

Professor Shen hurriedly shouted into the invisible switch: "Quick! Stop it! Call the ambulance crew! ”

"It's okay, calm down." I patted Professor Shen on the shoulder and comforted him.

Although I know it's okay, but Haoyue's finger has been cut off partially, the incision is still very terrifying, neat, and there are burn marks, all of which are exposed, Haoyue frowned and rubbed the wound of her finger, and after a few seconds, countless small red insects drilled out of the wound, reweaving the shape of her fingers and nails - she has the ability to regenerate instantly, I have already understood it when I cut my own flesh before and treated my leg, and I have been taught it, under the influence of Haoyue's bloodline, I also have the ability to regenerate, but the recovery speed is much slower than hers.

Professor Shen watched in surprise as Haoyue's fingers grew, and then looked at the severed finger on the ground suspiciously, probably thinking that she was playing tricks: "This ......"

"It's really high-tech, okay, let's go." Haoyue smiled.

Professor Shen didn't dare to ask more, and continued to lead us forward, but there were not so many words, and the pace quickened a lot, probably because he was frightened.

At the end of the corridor, turn left, and enter an access control, which is the laboratory I saw in the small video of the iron door just now, many people in white coats are busy in front of the computer, I looked at their computers, most of the content, I can't understand, what formulas, curve charts and the like, there is a guy I understand, it is the anatomy of a pistol, 3D, back and forth.

The young man found me paying attention to the side, looked at me, saw Professor Shen, and immediately got up to greet him.

"Xiao Wang, introduce this weapon to the guest." Professor Shen said.

"Yes, Mr. Shen, this gun is a single-person micro-sound small-caliber self-defense weapon newly developed by our third group, with a gun weight of 230 grams, a reserve of 8 rounds, an effective range of 15 meters, a sleeve and a muffler integrated, and a noise of less than or equal to 40 decibels when shooting."

"40 dB...... What is the concept? "I asked, not quite understanding.

"That's probably what I'm talking about now." The young man's voice was a little softer, simulating 40 decibels.

I nodded, it's already very powerful, I was hit by Zhou Tianwen with a gun at close range, the vulture's gun didn't have a muffler, the sound was very loud, like a second kick exploding in my ears!

"Chief, are you interested?" Professor Shen asked, and the young man listened to his teacher call me the leader, and he was slightly stunned, and slowly sat back.

"It's okay, that's it...... The effective range is a bit too close, only 15 meters. "I don't know how to pretend to understand.

Professor Shen frowned: "15 meters is still ...... Okay, since the leader said it, let's rectify it immediately, how many meters do you think is appropriate? ”

"It's going to be 50 meters." I said casually.

Professor Shen gritted his teeth and turned to the young man: "Did you hear that?" Redesigned to an effective range of 50 meters! ”

The young man looked bitter and wiped the sweat on his forehead, it seemed difficult?

Continuing to walk forward, I secretly asked Haoyue, "Did I say the wrong thing just now?" ”

"I don't know, I don't understand either, it's good to bring Ah Kun." Haoyue whispered.

Indeed, Ni Kun knows a lot, it doesn't matter if I say the wrong thing or even make a fool of myself, the key is that I am afraid that what I say casually will be taken as an order by Professor Shen and affect the normal work of others.

However, I think that the effective range of a gun is only 15 meters, which is indeed a bit short, and I directly throw bricks, isn't the decibel level lower, but also environmentally friendly!

Passing through this room, there was a laboratory inside, but Professor Shen didn't take us in, and directly turned into a room on the right hand side that said "Weapons Display Area", after entering, it was a large exhibition hall, similar to a museum, and there were many individual display cabinets in the room, covered with cube glass, and there were all kinds of weapons inside.

"Are they all small weapons?" I looked around and asked, mainly about pistols and gadgets that looked like pistols.

"Yes, our main procurement targets are the staff of the security services, commonly known as 'special attack'." Professor Shen said.

"I see."

"These are all finished products, chief, you can take whatever you like." Professor Shen said with a smile.

I looked around, and I felt that there was nothing special, I wasn't a special attack, and besides, there was Haoyue by my side, a small pistol in my hand, and the increased combat power was less than one-ten-thousandth of Haoyue's "Rainstorm Pear Flower Needle", and I couldn't afford to risk the sin of "hiding weapons".

Hao Yue fell in love with a small object, Professor Shen took out the weapon called the "Air Slingshot", but shook his head helplessly: "The Ginseng Immortal is really merciful, and he chose a weapon with the lowest attack power." ”

"How's that?" Haoyue asked, saying that it was a slingshot, but there was no handle, only a pair of rubber bands, and a spherical device attached to the rubber band, about the size of a golf ball, and the appearance was very sci-fi, with colorful fluorescent flashes.

"This is a gadget invented by my niece who has nothing to do," Professor Shen retrieved the slingshot from Hao Yue's hand, used his right hand as a slingshot stand, pinched the ball with his left hand, pulled it full, and aimed at the cube glass cover containing the slingshot, only to see that the colorful fluorescence on the ball began to flicker violently, and at the same time made a buzzing sound, two seconds later, the ball suddenly turned pure white, "This is the charging process, there is an air compression device inside, forming an 'air bomb', and you can release it when you let go." ”

After speaking, Professor Shen let go of his left hand, snap, the air bomb was invisible, and I only heard a "dang" sound on the glass cover.

"That's it?" I frowned and asked, there was not even a white spot left on the glass, I didn't feel as powerful as a golf ball!

"So it's a gadget," Professor Shen said with a smile, "using air as a projectile, the power is so low that even a rabbit can't kill it." ”

"Then why are you still here?" I asked, isn't this an arsenal, it's a toy.

“…… My niece is in charge of this," Professor Shen smiled wryly and put the slingshot back into the container, "That kid is more willful, and I can't talk about her." ”

"I think that's pretty good." Haoyue lifted the cover, took out the air slingshot again, followed Professor Shen's example, pulled it full, charged the small ball, and aimed at the door in the far side of the showroom.

"The range is not that far," Professor Shen said, "is only five or six meters." ”

Haoyue curled the corners of her mouth and squinted at me: "Yifan, remember I told you, what kind of shaman am I?" ”

"What?" I was stunned for a moment, "Oh, wood, earth...... Fire? Three attributes. ”

He was a shaman, who taught me my grandmother.

"Fire is qi," Haoyue said, continuing to stretch the rubber band, until her two arms were almost flattened, and the rubber band was stretched to more than a meter long, looking like noodles, and seeing that it was about to break, collapse!

I actually saw a small fireball come out of the "golf ball" and shoot towards the door at a very fast speed, and with a loud bang, the door was actually shot through......
