The four of them entered the teacher's office through the open balcony door. This office is supposed to be the largest room on the first floor, with an attached laboratory on one side. After all, life science is a science that attaches equal importance to theory and practice, and it is one of the most important scientific fields in this society.

Aaron, as the leader of the four, took the lead, followed by Lei Yan, Phoebe, and Shadow Lord.

The door to the hallway of the office was open, and there was no sign of any breaching—the thunderbolt had undoubtedly picked the lock to enter. The four of them came to the hallway, and under Aaron's leadership, they turned right and walked to the end.

The building was designed with terraces for only the two central offices. So they had to sneak in from the central office and go through half a corridor to the target office at the end.

"I saw it when I first came over, and there were three cameras along the way." Lei Yan pointed towards the end of the corridor, "It's not that there are no shooting corners, but I guess it's a bit difficult to avoid them completely...... Besides, we are four people. ”

"It doesn't matter." Aaron replied confidently, "I've hacked into the security system here on the sixth floor beforehand, and arranged for the three cameras to record the footage. Although it is not as clean as a professional hacker, if it only hacks a few cameras, no one should have the leisure time to check the clues left behind. So we're safe for now. Just on the way to the past, it's best to make a light move...... In my experience, students on this level should not be clean. ”

Sure enough, as Aaron expected, on the way to Mr. He's office, they passed by several lighted research rooms. It seems that some diligent graduate students would rather be locked in this office building by security guards than delay the progress of their research.

As they passed by the labs, all four of them deliberately slowed down.

They then passed through a number of small offices with locked doors and dark lights, a makeshift biomaterial cultivation room, a high-risk laboratory with a radioactive sign on the door, and a shared toilet on the east side of the floor, before arriving at the door of the target's office.

Aaron glanced up at the door number, "627." This is it. Then he raised his hand and twisted the doorknob.

When the doorknob turned, there was a "click" sound when the spring was stuck, and it seemed that it was locked.

"I'll give it a try." Lei Yan said.

Aaron then stepped aside.

Lei Yan took a step forward, first turned the doorknob, sounded to confirm the possible internal structure, and then took out a bent wire out of nowhere and stabbed it through the keyhole.

Phoebe also curiously came over to watch.

The two of them stared at the delinquent young cat who was wandering the underground arena and picking the locks there.

"Anyway...... Aren't you boxing? Why would you do such a thing? Phoebe asked curiously.

"I'm an orphan." Lei replied.

"Oh? What does it mean......"

"What do you think I didn't have the ability to work when I was young?" The head of the person who picks the lock does not lift it.

"By what?" Phoebe didn't understand.

"......" Lei Wei was obviously stuck. If it weren't for the delicate work of unlocking, he wouldn't have allowed people to look around, and he really wanted to look back to see if there was really a sunny and snowy expression on her face. After opening the first buckle in the keyhole, Lei Yan organized the language and replied, "When I was young, I was thin and didn't look good. At that time, even if they wanted to sell themselves as servants, no traffickers were willing to accept them - they didn't like children like me who didn't seem to live for a few years. So when I was younger, I had to pick up garbage for a living, and there were a few days every winter when I felt like I couldn't survive...... I didn't know how to survive. After growing up a little, I felt that I should at least learn a few crafts, and solve the problem of food and clothing first. So I went to the slums and worshipped two famous masters - one taught me how to pick locks, and the other taught me boxing. ”

is obviously a very painful experience, but Lei Yan seems to be telling someone else's story, straightforward and indifferent. After hearing him say this, Phoebe felt that she shouldn't have asked, so she muttered a sentence, "I'm sorry...... Mention your sad things. ”

"What's the ...... here" Lei Yan broke the wire, twisted the angle to make the final adjustment, and after a while, there was a "click", the door lock opened, and he straightened up and continued, "The original people who live in this country, it stands to reason that no matter who they are, they must have some such experiences...... Isn't it? ”

Aaron stood aside and let out an almost inaudible "huh". He is an original person who has had an identity since he was a child, and he suddenly sold miserably to those original people who have no identity - he has no good feelings.

Just when the three of them were about to open the door and enter, they heard a muffled sound of "bump-" behind them.

The sound wasn't that loud, not much louder than the sound of the door closing, and it could only be heard within a few steps, but the sound was so close to them that Aaron, Phoebe, and Thunder all turned their heads almost nervously to look in the direction of the sound source.

I saw a primitive student fall face down on the ground, as if he had fainted. The Shadow Owl was bending down, just grabbing the back collar of his coat, and was about to pull it up.

Aaron looked surprised: "What's going on......?" ”

"Oh......" Shadow Stalker turned his head, still holding the man's collar in one hand, and pointed to the toilet behind him with the other, "Just when you tossed that lock, this man came out of the bathroom and looked here as if he was going to call the police, so I knocked him unconscious......"

"And what are you going to do now?" Aaron frowned slightly.

"Drag it in for a while?" Shadow Owl pointed to the men's restroom again.

"I'll go with you." Aaron used to walk ahead.

So I saw two boys dragging the body of the fainted boy, one after the other, into the men's bathroom......

"It feels...... Isn't that weird? The corners of Phoebe's mouth twitched.

"It's okay!" Lei Yan smiled, "Even if it is really killed, it is better to leave the body hidden to Aaron to deal with." ”

With that, he unscrewed the doorknob and walked in first.

Phoebe shook her head vigorously, then stood by the door and watched the wind, and saw that Aaron and Shadowlord had settled and the knocked out passers-by were walking back, and they also entered the office. Before entering the door, I heard them muttering in the back.

"How long do you think he'll be in a coma?"

"One night?"

"You said you just punched him in the back of the head and could get out all night!?"

"Oh...... If your physical fitness is not very good, or if you have a problem with your cervical spine, it is possible that you will be in a coma until tomorrow afternoon. ”

"How hard did you go!" Aaron rubbed his forehead with a headache, "I am still doing experiments at this time, but I am a pillar of the country in the future, don't be stupid by your knife......"

Shadow Owl grabbed his hair and hesitated, "Probably not......

As the shadow lord was the last to walk into He Yingjie's office, he closed the door with his hand, and the four of them met again in the office.

In order to reduce the attention of others to this office as much as possible, Aaron did not turn on the headlights when he entered the door, but only turned on a small lamp on his desk.

Under the dim light, Phoebe sniffled vigorously, her eyebrows furrowed, "What does this smell like!?" ”

"Hold the fluid." Aaron said lightly, looking around by the light, "In the laboratory of the Department of Life Sciences, there are often some spare biological tissue materials, medicines, reagents, and the like. It doesn't smell good, but it's not poisonous. ”

It's a sizable office, and because it's so spacious, there's even a wall that's completely turned into a full-top bookcase, filled with all sorts of literature that makes me dizzy at the sight of a name.

The bookcase faces the door, and on the left side against the wall is a desk with a personal computer.

To the right of the bookcase is a huge, buzzing freezer that doubles as both freezing and refrigeration for perishable materials and reagents.

Next to the experimental cabinet is a material shelf, on which are neatly stacked glass bottles of different sizes, filled with a light yellow solution, soaked in some unknown pieces of meat, plant roots, bones, animal specimens, etc...... Phoebe glanced at the shelf, and immediately looked like a vegetable. And the bad smell just now is obviously coming from the glass bottle.

Further inside the material shelves is a glass door that leads to the lab, with the same configuration as the other large offices. The laboratory inside is equipped with a laboratory bench and a variety of high-end instruments, and the sound insulation and shockproof effect of the laboratory are very good.

After looking around the environment, Aaron spoke: "This office may contain key materials that will allow all of us to pass the final examination of 'Winged Humanization', and it must be thoroughly searched, and no corner can be spared. ”

Everyone nodded in agreement.

"So, Shadowlord, you go inside the lab." Aaron began to assign tasks, "There should be some equipment in the lab...... Go and see if there's anything suspicious. ”

"Phoebe, please search the bookshelf."

As soon as she heard that she didn't have to toss the bottles and cans with strange things, Phoebe breathed a big sigh of relief: "Okay, good! ”

"I'll go and see if there's any important information left on the teacher's computer." Aaron continued, "I'll leave the bottles and cans over there, Thunder. ”

The hedgehog head made an OK gesture.

Those pieces of meat and organs can kill Phoebe, but for Lei Wei, an underground boxing champion who is used to fighting in the arena every day, it is simply a piece of cake. So he agreed easily.

Now that the division of labor is complete, everyone is ready to act.

Shadowlord pushed the door open and entered the lab. As Aaron did when he entered the door, he didn't turn on the lights. Just operated the video headset, and a flashlight-like pillar of light illuminated the space more than ten meters in front of him.

Looking through the pillar of light, the entire space was scattered with floating dust. It seems that because of the disappearance of the owner of the office, this place has not been cleaned for a few days.

Shadowowl walked over to the wall, which was a three-meter-wide test bench. The table mask is in a glass cover about 1 meter high, and only the side of the person, close to the table surface, exposes a gap of twenty or thirty centimeters high, so that the experimenter can put his arm into it to perform aseptic experiments.

On the desk next to the bench are reference books of various sizes, and at the top is a very thin booklet with the words "Pterygoma Case Study" on the cover.

"Only those who have wings will grow this kind of tumor, right? That is, the ...... of diseases that winged people will get? Shadowlord muttered, "It seems that growing wings isn't all good. ”

Continuing to look down the tabletop, there is a cheap paper photo frame in the innermost part against the wall. The Shadow Owl picked up the frame and dusted it off, looked at it by the light, and found that it was not a photo, but a handwritten note: Come on! My hero.

Signed by: Evelyn. White

"These two guys really have a leg." "So this woman must have a disease called 'pterygooma', and the man went to study a cure for this disease." ”

Putting down the frame, the Shadow Owl walked around the house a few more times and searched around. It turned out that there was nothing left in the lab, except for expired potions, moldy petri dishes, dusty test benches, and some research reports that couldn't understand what was being said.

Shadow Owl grabbed a few pages of the report he couldn't read, pushed the door open and returned to his office.

Aaron was still sitting in front of the computer, his hands rapidly typing on the keyboard.

Lei Yan carefully searched the material rack, and picked up every bottle and jar that could be moved and looked at it. Like a child who has discovered a new toy, he shows a strong interest in each piece of the display.

Phoebe's task seemed to be the most onerous - although she was probably the most educated person on the scene except for Aaron, it was understandably difficult to look through hundreds of specialized books in the dim light. Visually she's now screened two-thirds of them, which is already an astonishing speed.

Shadow Owl walked behind Aaron, deliberately made a noise to attract his attention first, and then put the research report in his hand next to the computer, and said, "There are a lot of books related to this disease in the laboratory, what is it called-pterygooma." The woman must have this disease, and it looks like it is difficult to treat, while the man seems to be looking for a cure. ”

Aaron glanced at the information Shadowlord had brought in, typing his fingers on the keyboard for the last line of commands, and pressing enter. A large amount of text instantly poured out of the white screen, overwhelmingly stacked into many overlapping windows. He picked up the mouse again, dragged and dragged on those windows as if he were looking for the materials he needed from a large pile of documents, and finally picked out a neatly formatted document and put it on top, and said: "Pterygoid osteoma is a terminal disease that only winged people can suffer, and you can understand it as a kind of bone cancer. However, because only the bones on the wings will grow this malignant tumor, it will not appear on the original body. I guess both Ho and Evelyn thought at first that Evelyn was suffering from this 'pterygoma', because I found the diagnosis of the disease in this computer. Aaron gave way to the left so that the shadow owl standing on his right could clearly see the screen - the top document was indeed written as Aaron said, a doctor named Li Hao issued a "pterygoma diagnosis report" to Evelyn, and the date of diagnosis was November 21, 2038, that is, almost half a year ago.

"However, I just found another diagnostic report from this computer's encryption program." Aaron said, picking out another document from the pile with his mouse, "The date of diagnosis is April 11 of this year, and it turned out to be stomach cancer. ”

"So Evelyn's illness isn't pterygoma, it's stomach cancer?" Shadowlord asked.

"Seems so." Aaron nodded, "He Yingjie's previous research seems to have been in vain. ”

As the two were talking, Phoebe, who was searching the bookshelf on the side, had also completed her task, and seemed to be walking towards this side with something.

"What did you find?" Aaron asked.

Phoebe looked at the things in her hand and replied confidently, "Decisive evidence." ”
