The third clinic of the Imperial Academy of Sciences and the Institute of Higher Life Sciences welcomed an uninvited guest today.

It is said that it is an uninvited guest, but in fact, with the identity, status and military rank of this visitor, it should be the kind of guest who Professor Sun Lin, the head of the third consultation room, often needs to sit upright and deal with it seriously with a set of professional terms. Sadly, however, the visitor's name was Carl. Orlando, the disciplined and rigid style of the military is simply not present in him.

"Professor, how much can you sell for this can of 'ultra-long antiseptic and antibacterial specimen treatment solution' that you prepared yourself on the market?" Carl stared with interest at one of the bottles in the cabinet in the exam.

"You can't sell it, Lieutenant." The professor's usual old-fashioned tone was mixed with anxious emotions, "Everything in it is counted, even if it can't be used, it must be destroyed, and if it flows to the market, it will be held accountable......

"I mean, like? For example, if I accidentally take a bottle and take it to the underground black market as a ......"

"Lieutenant Orlando! If you talk nonsense, I'm going to report it to the Discipline Committee! ”

"Okay, okay!" Karl whistled to the sky, "Professor, you are such an old man, why can't you still make the slightest joke...... Am I like that kind of person who does nonsense? ”

"......" Professor Sun Lin glanced at him helplessly, the subtext - you are simply so.

"Then you think it's ......" Karl raised his hand in surrender and asked again, "Phoebe's cultivation wing, when can you show me?" ”

"When is Second Lieutenant Ito coming?"

"Can't he watch it if he doesn't come?" Karl pointed to the two stars on the epaulette dissatisfiedly, "My military rank is higher than him!" ”

"Ahem-" Professor Sun Lin didn't even look at him, sat behind the desk without the slightest intention of getting up, cleared his throat and said, "In December last year, Lieutenant, you went to the fifth consultation room. It's not important, just ask some basic life science knowledge that even high school students know. But after you left, a few of the high-potency marijuana plants grown in the fifth clinic were stolen......"

"What's ...... that to me?"

"A week later, the guards found the name tag of one of the marijuana strains in the room of a former girl at the 'Wheel of Dreams' bar in the South End."

"......" Karl's face became a little embarrassed.

"In March of this year, you went to the second clinic of the Poison Research Institute again and asked the question, 'Who is more venomous, king cobra or krait'. But after you left, the high-purity amphibian toxins that had just been extracted from the second clinic were stolen......"

"Alright, okay, I know!" Karl interrupted the professor loudly, folded his hands in front of his chest, sat down on the sofa for visitors at the door, and said angrily, "Isn't it okay for me to wait here for Naoto to come...... Don't nag your old man. I'm still holding a grudge so much when I'm old, be careful of being hated by girls......"

This guy ...... Is there only a woman when you open and close your mouth?

Professor Sun Lin sighed with hatred - the Demon King of the Mixed World of Marshal Yuheng's Mansion came this time to clamoring to see the cultivation wing of a certain female soldier, I'm afraid he is not playing some kind of ghost idea again, right?

He glanced over to Karl. I saw the red-suited blonde lieutenant lying on his legs in boredom, spread out on the visitor's sofa, and jazz music could be heard even from his position in the video headphones.

The professor shook his head helplessly again, saying that it would be nice if this Carl had half the life of his brother.

However, Karl's squire, Naoto Ito, was a model of a good soldier.

From the time he received Karl's contact to the time he showed up in the third room, it took him less than a quarter of an hour. Presumably, he is very obedient to the orders of the commander, and his execution is also first-class.

Second Lieutenant Ito pushed open the door, saw Karl slumped on the sofa, and immediately saluted the chief.

Carl listened to the music and shook his head, nodded slightly in response, and beckoned to Professor Sun Lin behind the desk while catering to the tune, and asked locally, "Is it okay now?" Professor...... Can you take me to see Phoebe's cultivation wing? ”

The professor was angry, but when he saw Naoto Ito's exemplary face, his heart softened, and he stood up from behind his desk: "Come with me." ”

"Great!" Karl shook his fist in the air like a big boy who saw his favorite player score a goal.

Under the leadership of Professor Sun Lin, the two red-clad officers circled most of the hollow hanging corridor on the fourth floor, and after entering the training hall, they were turning around in the labyrinthine corridor of cubicles. Just as Carl was about to start complaining, the professor stopped.

In front of them was a huge metal barrier—more than ten meters wide and more than two stories high. The three of them stood in front of the door, as small as ants moving bricks.

"Up front of this is the cultivation wing storage room." The professor spoke, "70% of the Empire's cultivation wings are stored in the space behind the door. Be very careful when you go in. ”

Naoto Ito stood up straight and said, "Understood." ”

"Huh? Only 70%? Carl still looked like a hanger, and his voice slouched out, "Where are the remaining 30%?" ”

The professor glanced at him, "Confidential." ”

Next to the huge isolation door of the storage room is a front desk machine that looks like an ATM, two meters above the ground, embedded in the wall. The professor flew up and the screen was turned on after his fingerprint was verified.

“UX-3976。” The professor gave an unclear figure.

"The system is checking, please wait." A soft female electronic analogue voice came from a loudspeaker near the machine.

Karl flew silently behind Professor Sun as if he had seen a cat with a ball of yarn, his dark red eyes flashing with curiosity.

After more than ten seconds, the electronic voice continued: "Checked. Professor Sun Lin, please enter your guest ......"

Beep –

From behind the professor stretched out a large, slender and powerful hand, with its index finger pressed against the fingerprint reader.

The hand reached out, silent like a ghost. The professor was startled and quickly turned back, only to see Karl winking at him mischievously. Professor Sun suddenly felt that he had never been so hopeful in the past few decades to carry a life-saving medicine such as a 'fast-acting heart pill'.

"Carl. Lieutenant Orlando. The electronic tone accurately reported the identity of the owner of the fingerprint.

Karl stepped aside and said to the man behind him, "It's your turn." ”

Naoto Ito politely nodded to the professor, "I'll take my fingerprints now." ”

If only Carl could be as cultivated as his squire! ——Professor Sun Lin had a new sigh in his heart.

"Second Lieutenant Naoto Ito." The electronic voice said again.

"Done." Sun Lin's slightly old voice echoed in the empty space, "Please open the door." ”

"Understood." The electronic voice mechanically responded, "The isolation door is about to open, please retreat to the position behind the yellow line." ”

Two rows of indicators are buried in the walls on both sides of the door, from top to bottom. As the electronic sound starts, the indicator lights up one by one from top to bottom, forming a light curtain composed of overlapping yellow rays in front of the door, which is spectacular.

"Wow - high-tech!" Carl sighed and flew two steps backwards.

The dense metal circuits on the isolation door, like a circuit board, struggled to turn, making a loud grinding sound, and the door slowly opened.

Behind the door is a huge number of training cabins, which account for 70% of the total number of training wings in the country.

Despite their mental preparations, Karl and Naoto Ito were shocked by what they saw when the door opened completely.

Densely packed with honeycomb-like storage shelves, the pipelines for the transmission of liquid and electricity hang down from the air to the ground, and the air is filled with the strange smell of evaporation of the culture medium. All the cultivation chambers have their own power supply lines, and the small electric current sounds of countless mosquitoes and flies flying in their ears are intertwined, converging into a low-frequency noise like spiritual pollution.

The incubator is a vertically arranged glass jar filled with a pale yellow culture medium as viscous as plasma. Cells collected from the host are put into this jar and grow into winged human wings that can be transplanted into humans over the course of months or even half a year.

Professor Sun led two soldiers through the glass jungle, following the area guide markers to find their targets.

The wings in the training cabin are large and small - after all, the age of the wing-planting subjects who are issued indicators varies from a few years old to dozens of years old. As a result, some of these wings look as small as the young feathers; Some are already sparsely feathered, faintly visible green tendons looming under the skin; Some of them are sturdy and robust, and they look impeccable from any angle.

Sun Lin stopped in front of a pot of culture liquid that was so pale that it was almost transparent, and quickly found the metal label inscribed on the metal base at the bottom of the culture chamber, number: UX-3976.

"That's it?" Carl asked.

"Yes. That's it. ”

The storage room of the culture wing is filled with countless storage racks for culture cabins. Nearby, there is only a narrow gap between the two storage shelves that can be passed by one person. The shelves are neatly arranged and look like a whole piece of honeycomb compartment from a distance, and the visual effect is quite stunning. However, if you look closely, each storage rack is actually an individual that can be carried. A single storage shelf covers an area of only a few square meters, and the structure is divided into three layers, each layer accommodates six cultivation cabins, and shares a metal base. The individual chambers resemble a capsule placed vertically on one of the corners of a hexagonal metal base.

The pod in front of them was placed on the middle floor, and the three of them could only hover in the air to observe the unformed wings in the cabin. Professor Sun flew to the right side of the capsule, and a control panel was embedded in the bulkhead. After turning over the bezel on the panel, after fingerprint identification, a large amount of text information is displayed in the air through projection, forming a virtual screen.

Name: Phoebe

Individual Information: Adult female

Indicator Approver: Carl. Orlando

Employer: Carl. Orlando

Culture start date: May 14, 2039

Estimated completion date: October 2039

Project Leader: Lin Sun

Underneath these summaries are a large number of numerical values, charts, report copy, and so on that the layman will not understand......

Carl looked at the contents of the pod with interest, the unformed wings curled up in a ball like the wings of an unhatched chick. Most of the epidermis is exposed, except for the two largest wing bones with scattered hairs.

Karl glanced at Naoto Ito, who immediately asked in understanding, "Professor, how is this wing doing?" ”

"So far, it's been very smooth, and all the values are in a healthy range." Sun Lin's pupils quickly rotated left and right along the large pile of data and charts, and he said with the appearance of an expert, "The formation period of the cultivation wing generally ranges from 4-6 months, and the first month is the one that is more likely to have problems. You see, now that a month and a half have passed since the start of culture, it can be said that the organ has entered a stable period, and then it will develop and form step by step. ”

"In other words, it will be ready for transplantation by October?" Ito asked.

"If it's fast, you don't even have to wait until then." After reading the report in his hand, Professor Sun took off his monocle and wiped it on the hem of his white coat, "Numerically, the host of the wing is also a very energetic individual. In order to cooperate with the planting wings, she would come back every two weeks regularly for check-ups and injections of some transformation hormones or something - and this is also going well. In my experience, by mid-September, you should be fully prepared. ”

"September ...... That was two months later. Ito calculated the time.

While the two were talking, Carl was flying around, already looking at the other five training wings on the same storage shelf, and then stopped in front of the training pod diagonally opposite Phoebe's training wing and asked, "Whose wings are these?" Why is it such a big man? ”

Sun Lin was seriously explaining to Naoto Ito, and was suddenly interrupted by such a person, and he didn't want to pay attention to him. But Ito's side was no longer interested in Phoebe's wings, so he naturally flew to Carl's side, and Professor Sun had to sigh, turn off the control panel here, and fly to the lieutenant's side.

The professor glanced in the direction of Carl's gaze, and then seemed startled, "Why did it get bigger again!?" After saying that, he ran and pressed the button on the control panel of this training cabin to make the virtual screen pop up.

Naoto Ito also flew up to Karl and looked into the training pod - sure enough, it was a pair of young wings that were much larger than Phoebe's. The skeleton of these wings looks beautiful—rounded curves, strong muscles, stretched tails, snow-white feathers, and although the feathers on the wings are still very young, from the flutter of the wings, you can feel the aggressive aura of a bird of prey like an eagle or a falcon. Another point - these wings are nearly twice as large as Phoebe's wings.

Professor Sun looked at Tsubasa's explanatory document, but his expression became more and more serious.

Karl glanced at Naoto Ito again, and the latter asked understandingly, "Professor Sun, is there something wrong with this wing?" ”

If this kind of correct question had been asked by Karl, it would have been suspicious of the professor and would not have answered; But once the question comes from Naoto Ito, even the most ridiculous question, these old-fashioned professors will feel that there must be a reason for asking such a question. This mentality is actually very similar to the difference between the teacher's mind in the pre-exam class when facing the questions of the top students and the questions of the poor students.

In view of this, Carl will always let Ito ask important questions, and he has always played the role of a gag and mood-regulating type.

Sure enough, the professor who heard the question replied without raising his head: "The problem with these wings is very big...... From the first week of training, he was in frequent condition, and he almost died. I almost sent the best experimenters under my staff, plus I myself dealt with all kinds of emergencies 24 hours a day, so that this thing grew up unharmed to the size it is today. At this point, the professor sighed haggardly, "I didn't expect that...... In the past two days, there has been another problem with the proliferation of wings. Sometimes it multiplies rapidly, and sometimes it devours each other, so that the mass of the wings is sometimes large and sometimes small, and the values are up and down like an electrocardiogram, which almost drives the researchers in my office crazy. ”

It sounded like a terrible thing, but Karl's eyes were full of curiosity: "Professor...... Whose wing is this? ”

It's okay not to ask this question...... With this question, Sun Lin had to look at the attribute information on the control panel again, and then he was angry.

"Are you embarrassed to ask......" Professor Sun Lin, who has always been a serious person, gave Carl a rare white look, "This indicator is also approved by you!" ”

"Huh?" Carl squeezed his eyes, "Are you sure?" ”

Professor Sun pushed the control panel towards him: "I don't believe you can see for yourself. ”

Carl leaned over and saw a virtual display pop up in the air in front of the panel, and a large amount of text information was being projected line by line.

The message in the first few lines reads like this-

Name: Shadow Owl

Indicator Approver: Carl. Orlando
