A terrible siren sounded over the academy, and everyone stopped what they were doing and raised their heads in unison. Pen ~ fun ~ pavilion www.biquge.info

"Please all non-combatants immediately take refuge in the bunker, security commissioners please immediately go to the main building to assemble, this is not a drill, repeat, all non-combatants are requested to take refuge in the bunker immediately, security commissioners please immediately go to the main building to assemble, this is not a drill, repeat, this is not a drill." A cold and hard female voice echoed in midair, "The safety zone has entered a state of first-level alert, please follow the red emergency plan to avoid danger." ”

Everyone's face changed, the first-level alert state is the highest alert state, entering this state means that the academy has been in the city, the academy has never entered the first-level alert since the establishment of the security zone for three years, the first-level alert response plan is printed in red on the last page of the "Safety Manual", although the academy will rehearse it every year, but no one thinks that the academy will really fall into such a dangerous situation.

The so-called Level 1 Alert, like the Nuclear War Evacuation Guide, is the worst-case scenario for the future, and once this response plan is activated, it means that the end of the world is not far off.

Because of the prerequisites for entering the first level of alert...... It's the academy that has been invaded.

The alarm came suddenly, and it came up to be a level of alert, which is like two countries at war, the other side will not slowly send infantry first, then send tanks, and finally get on the plane, and the missiles will gradually increase the difficulty from novice to difficult, that is to play a game, the real war should be like the German invasion of Poland back then, the steel torrent composed of tanks and armored vehicles drowned all the resistance of the other side with lightning speed, and it was a nightmare or even hell difficulty, and a stick was stunned.

This is the cruelty of war, you don't have time to warm up, you don't have time to hug and say goodbye, it takes everything away and destroys.

Doctors, electricians, cooks, nurses, and engineers left their work without saying a word, and rushed into bunkers with their heads in their hands, and shelters like air-raid shelters were built under the main buildings of the college, each of which could accommodate twenty people, and there was enough food and water for ten people to live for five days.

These shelters were not actually built by the upper echelons of the academy, and the security zone only inherited the legacy of the Shanghai Naval Military Academy...... These bunkers were built in the fifth year after the outbreak of the apocalyptic virus crisis, when everyone was at risk and shelter bunkers were the standard in all safe zones, and people dug these tunnels underground to resist the attacks of zombies and hunters, and the doors and windows of each bunker were specially reinforced, and food and water were stored in them, so that people could huddle in bunkers until help arrived if they were attacked and besieged by hunters.

Today's academy uses the same shelter as it used to be, so it also stores enough food and water for five days, but in reality this number is no longer meaningful...... In the days when bunkers were just being built, five days was enough to wait for rescue troops to arrive, but now that the world is ruined, there are no more rescue teams, and hiding in bunkers only extends life by five days.

The security services quickly assembled, and strong men in combat uniforms rushed through the playground into the main building, and the storekeeper appeared in the hallway with a small cart and lifted the tarpaulin covering the cart.

The men removed their rifles, slapped the magazines into the magazine, opened the safety to pull the bolt, hung the spare magazines and grenades on their chests and waists, and put on their headphones.

The veterans frowned and were relatively silent, many of them were comrades serving in the same team before entering the security zone, and they could read each other's thoughts with a single glance.

A faint sense of unease spread among the crowd.

These veterans are far stronger than ordinary people, but they are as powerless and fragile as newborn babies in front of hunters.

"Attention everyone......" a deep male voice came from the headphones, "I will now begin to assign combat missions. ”

"Colonel." All stand upright.

Belle glanced out the window, where a shrill siren sounded.

"Level 1 alert?" The girl was stunned and changed her face, "This afternoon is still a second-level martial law." ”

"Obviously, things are going much faster and more seriously than you think." Ariana stood in front of the window, her hands in the pockets of her white coat, looking at the people hurrying by in the clearing in the distance, her face was very flat, "Hunters are not creatures that follow the rules, they will not give you a war letter before attacking. ”

Belle frowned, "How is this possible...... What can get past the layers of defenses in the safe zone? ”

"You'll find out in a moment." Ariana whispered, "The higher-ups should be in a hurry, right?" ”

As soon as the words fell, a "buzzing" vibration sounded.

Belle and Ariana pulled their headphones out of their jacket pockets at the same time and put them on.

"Attention all the hummingbird hunting team, enter the first level of combat readiness." It was not the colonel who spoke in the headphones, but a young girl with a crisp and immature voice, "I will start assigning combat missions next......

The main building, the operational command center.

A young girl in a white dress stood in the center of the room, wearing headphones, holding the large stuffed teddy bear tightly in her hand, still stepping on a pair of blue plastic slippers at her feet, she looked up at the flickering screen on the wall, the surveillance equipment of the entire academy gathered all the information and intelligence on these more than ten monitors, more than a dozen different pictures jumped at the same time, dense numbers and words rolled from the screen, and the real-time refreshed images were reflected in the girl's sky blue eyes, she was motionless and did not blink an eye.

There was an extremely chaotic sound in the headphones, so noisy that it was like a cattle herding class after class, and the bustling voices of dozens of people were played at the same time, mixed into a fly-like "buzzing" sound, and ordinary people couldn't hear what was said in the headphones.

The girl's headset is one of the terminals of the college's communication network, through which she can collect calls from everyone on the whole channel and line, which is not normally usable because everyone's voices will be played at the same time, mixed into noise.

But the remixes were automatically disassembled in the girl's head, and in her ears it was no longer a jumble of noise, but dozens of people speaking clearly, and she was listening to dozens of people at the same time.

The girl paired the two people who were talking to each other in turn, and a vast network of communications and people took shape in her mind.

It's something that only a computer can do, but she did it in her own brain in just a few seconds.

Phoebe Christina, the pre-battle liaison and mission commander of the Hummingbird Hunting Team, codenamed "Tinbrain", is the only member of the Hummingbird team who has no combat power, but she is the heart and hub of the entire Hummingbird team, and she never needs to go to the front line to fight herself.

Lu Xun thought that Phoebe's mind reading skills were already incredible, but mind reading was actually just a pastime when Phoebe had nothing to do, and her real strength lies in the data collection and processing capabilities comparable to computers, the so-called "end brain", that is, the "terminal brain".

Phoebe Cristina, a humanoid computer.

The information of the entire academy is gathered in this girl's brain, and the serious Phoebe can complete the college exam papers of nine subjects at the same time, just like the multi-threaded processing method of the computer CPU, but this is far from the limit, and the full-fledged Phoebe is enough to crush the computer.

Her brain is rapidly processing all the information, sounds and images are fed through her eyes and ears, and then her brain begins to simulate the situation on the battlefield, evaluate the comparison of power between her own side and the opponent, she builds all the initial conditions into a model, then runs the model, and finally makes a prediction of the outcome.

Phoebe filtered the sounds that came into her head, leaving only the Hummingbird team, and the rest of the security personnel were not under her control, and the command of those people was in the hands of the colonel.

"Received at zero distance, in place." Luo Cheng said lightly, followed by the crisp sound of the clip snapping.

"Lemon received, it's in place." The girl said.

"Storm received! Mecha Launch! ”

"Iron wall received! Mecha Launch! ”

The roar of a gas turbine was heard in the headphones, followed by the grinding of machinery and metal, and a steel behemoth stepped out of the hangar, shaking with every step.

Like Phoebe, the entire hummingbird hunting team is firing on fire.
