At the same time as Xiao Liping reminded him, Gu Tie also discovered the arrival of an uninvited guest. The defense measures of the second layer base of Panshen Wine Cellar are very tight, and Gu Tie, who is connected to the quantum network through a military-grade central route, cannot obtain control permissions, so he cannot monitor the images of hundreds of sensors in real time. But this is not a problem for the Chinese, just now when he entered the monitoring room he secretly threw a miniature camera glued to the wall, through this networked pinhole camera device, he can see the whole room on all the screens of the scene. In the upper right corner of the field of view, he has been maintaining a small window of the quantum network, Gu Tie magnified the camera screen, and fixed the focus on the B3 screen, which is a composite monitoring device of ground penetrating sonar - infrared sensing - vibration sensing, and a few lines of text are scrolling quickly on the screen. The overhead light suddenly dimmed, "The combat readiness level of the base has been automatically upgraded to level four, what the hell ......" Xiao Liping dropped his wine glass and strode out of the room, Gu Tie flicked the cigarette butt to the ground and crushed it, stood up and followed behind Lao Xiao.

Xiao Liping walked into Room 1 and sat in front of the center console, using fingerprints and DNA identification to turn on the weapon control system. He clicked a few times on the touchscreen, and the B3 surveillance screen fell out, and a three-dimensional model of the base appeared on the projection screen, a ring structure around a cube and a huge foggy area, like the 400,000-kilometer rings of Saturn, which guarded the sixth planet in the solar system. At this moment, there is an area above the cube room that is rendered bright yellow, which is a sign of a mild intruder threat, Xiao Liping's palm slid across the screen, a control handle slowly rose, he held the handle, and his index finger lightly rested on the red trigger with a transparent protective cover.

"What kind of weapon is this?" Gu Tie couldn't help but ask.

"Heavy particle launchers, one of the most mature energy weapons at the moment. Heavy particle emitters are ideal for traditional weapons that don't penetrate enough in the dirt, laser decay is too fast, and shockwave weapons can't be precisely targeted. Lao Xiao said in a deep voice, "This machine is jointly developed by the 203rd Institute of China Nuclear Power Corporation and the North Ordnance Industry Group, and the four launch compartments are installed above the buildings in the second, ninth, sixteenth, and twenty-first districts respectively, to ensure that at least three launch compartments provide energy for each launch to ensure the damage effect." ”

Gu Tie said in a low voice: "I remember that this thing was researched and installed on missile destroyers to fight aircraft carrier battle groups?...... The effect of jerking off is first-class, is it so suitable for whack-a-mole?"

Lao Xiao flicked open the protective cover with his index finger "horn", and said: "I have done some tests, and it will indeed have a negative impact on the formation structure, but the power can still be guaranteed." After these intruders are killed, I can shoot an 'eye' to confirm the results of the battle, after all, there are not too many such submersible robots, and I can't just spend it. ”

"Oh, that's good. Gu Tie nodded, and suddenly reached out and squeezed Lao Xiao's hand tightly, "But wait a minute." ”

Xiao Liping slowly raised his head: "You are interfering with me to protect our safety." Moreover, I should have made it clear that I have no interest in homosexuality, and I am a more traditional Chinese man. ”

Gu Tie smiled evilly: "Don't be, interest needs to be explored, I will start to get to know you again today, maybe sexual orientation is also a new topic." His right index finger and middle finger gently flicked on the back of Lao Xiao's hand, Xiao Liping felt a tingling sensation in his wrist, and involuntarily withdrew his hand, Gu Tie closed the handle protective cover with a "click", and leaned his body on the console: "I mean, don't be in a hurry to kill, what if it's a friend who comes down from the hole in the ground, and it will be blown up into a pile of protoplasm in such a muddle, isn't this the most miserable trip to friends in history?"

"This is not the time for jokes. Xiao Liping said coldly, stretched out his hand and poked the screen: "It took us so long to use the vertical shield machine to drive down, even if the silt in the tunnel is relatively easy to excavate now, but who can get professional submersible equipment so easily? The one who can catch up here in such a short time must be the son of God with abnormal abilities,...... I'm sure it's the Son of God we got rid of halfway, the Brotherhood killer who uses sound waves as a weapon!"

Gu Tie smiled: "Okay, gamble?"

As soon as these words came out, Lao Xiao seemed a little overwhelmed. This is a common joke between the two of them, in Beijing all day long, Gu Tie likes to bet with Lao Xiao no matter what happens, usually a bet on a meal, when Gu Tie is swaying around in the university and Lao Xiao is working hard in the officialdom, this meal refers to two bowls of fried liver worth 40 yuan, a cage of pork and green onion stuffed buns and two steaming tea eggs in a small fried liver shop in Dong Shishitiao. Money is not a problem, the problem is the attitude of spending money, compared to a big hotel where everyone is sitting like a dog, a small restaurant full of the smell of cigarettes, alcohol and Beijing scolding is more of an appetite for the two of them, Gu Tie thinks he is a vulgar person, and Xiao Liping feels that it is a meaningful practice to watch the world with a cold eye.

“...... Who do you think it might be?"

"Ghost people. Gu Tie then said, and the two tacitly put aside the embarrassing topic. "During the battle on the first floor of Panshen's Cellar, we escaped the ghost's surveillance, but at the last moment, the operation to break through the power distribution room and enter the second floor was so loud that there was no reason not to be detected by the ghost. To protect me—for whatever reason—they probably managed to chase me down. ”

Xiao Liping said: "First, how do you determine the identity of the intruder? Second, how do you determine whether the ghost is friend or foe? For the betrayer, the ghost and the brotherhood are just weights at both ends of the scale, and I don't believe that they are trying to protect your life in order to 'be friends with you'." ”

Gu Tie raised his eyebrows: "It's very simple." First, wait. Second, wait. ”

Lao Xiao frowned and said: "It's not an old monk, what kind of dumb riddle to play with me, you get out of the way, I'm going to start the heavy particle emitter, it will take forty seconds to precharge." ”

Gu Tie didn't say anything this time, took off the Omega Seamaster automatic chronograph watch on his wrist, set the timer on the outer ring to the forty-second position, and placed the watch on the console.

Lao Xiao said: "You mean to wait forty seconds? Okay, I beat this bet, I will charge the heavy particle cannon first, forty seconds will come, if you can confirm the identity of the other party is friend or foe, you win, I will lose you a meal of fried liver and steamed buns; if you can't confirm it, I win, you lose a meal for me, and then I will pull the trigger." ”

"Deal. ”

The two stretched out their fists and touched, Xiao Liping opened the protective cover of the handle again, and pressed the red trigger with his index finger. The first segment of the two-stage trigger represents the pre-charging, and the lights in the room are immediately dimmed, and the electricity output from the high-energy fuel cell begins to activate the electromagnetic channels and cooling devices of the heavy particle transmission tower, and the defense system automatically locks the crosshair in the yellow suspicious area, at which point the cross-sectional view of the area is becoming clearer and clearer as the frequency of the ground penetrating sonar changes, and three people can be seen slowly descending the mud-filled tunnel towards the top of the cube room.

"Three people. Gu Tie and Xiao Liping muttered to themselves at the same time.

Fifteen seconds passed, and the figure did not change. A low humming sound sounded in the distance, and Gu Tie knew that it was the sound of the heavy particle cannon starting to warm up the firing rail. He took out a Marlboro cigarette from his pocket and lit one and smoked it, Xiao Liping turned his head to look at him and didn't say anything.

Twenty-five seconds passed, and the figure did not change. The person at the bottom was already very close to the exit at the end of the passage, where the vertical shield machine was still stuck in the ceiling of the cube room, half inside the room and half in the dirt. "The best sniper opportunity has been missed. Lao Xiao said, "If you fire now, you will blow up the ceiling." ”

"Anyway, you don't know what that big house is for, and if it collapses, it will collapse. Gu Tie looked like he didn't care about himself, "By the way, when exploring the passage behind the twenty-four doors, how many people died in total?"

"Forty ...... What are you talking about?" Old Xiao spat out a few words and immediately turned his head to look at him vigilantly, "How do you know?"

Gu Tie shrugged: "Nonsense, if it were me, I wouldn't be staring at such a mysterious underground building." I guess these graphene-enclosed channels will block electromagnetic conduction, and the shape of the channels denies the usefulness of wired robots, and if you want to explore the channels, you can only use artificial intelligence robots (not yet networked models, only outdated built-in CPU chips), or live humans. For the Chinese, the first thing that comes to mind must be to send soldiers in, there is no mechanical thing more reliable than our PLA comrades. According to the law, a declaration of disappearance for two years after a major accident can be considered dead, so these 40 or so people are victims of this strange building. ”

Before Xiao Liping could speak, Gu Tie added: "Ah, the exact number is forty-four, right?"

This time, Lao Xiao only had two words written on his face: shock. "How do you know ......"

"Guess. I'm going to scare you to death. Gu Tie spread his hands triumphantly.

At this time, the watch jingled, the timer was over, and Xiao Liping lowered his eyes, "I'm sorry, you lost, brother." These three lives are to be taken over by me, and in order to fulfill the ultimate wish of the betrayer, all unstable factors must be eliminated. His fingers began to tighten, and the second trigger was about to be touched.

"Look. Gu Tie suddenly screamed and pointed to the screen. Suddenly, several white lines appeared on the screen, which were traces embedded in the soil around the passage and at a temperature of more than 500 degrees, which were identified by the infrared probe.

"Three lines, what does this mean?" asked Lao Xiao.

"Represents me winning, man. Gu Tie said.
