It was the summer vacation, and there were very few pedestrians on campus, and a man in his fifties walked slowly down the road with a large pile of materials, muttering from time to time.

"This kid, don't tell me when you go home!"

That's right, this person is Professor A, and the "this kid" he refers to naturally refers to Duan Pingsi, whenever he needs to move some heavy objects, he naturally thinks of Duan Pingsi.

"It shouldn't be, he left without saying hello to me, and the phone couldn't get through, this is not like his way of acting!"

Professor A said to himself that he hadn't seen Duan Pingsi for several days, and he couldn't help but feel a little worried, so he put the information on a stool on the side of the road and dialed the phone number of Zhang Yuhang's office.

"I'm Ah Tuan, is Zhang Yuhang here?"

A young woman's voice came from the other side of the phone, "Professor A, Zhang Yuhang no longer works here, he resigned a few days ago and went back to his hometown!" ”

"Then ......, is Duan Pingsi there with you?" Professor Ah asked again.

"Duan Pingsi? He's not our staff, is he? The woman was stunned for a moment, and then said, "Oh, he hasn't been to us lately!" Excuse me! ”

"It's okay, if there's any news from him, please let me know!"

"Okay! ……”

After hanging up the phone, Professor A dialed the mobile phones of Zhang Yuhang and Zhang Yu respectively, but found that the two of them also turned off their phones.

"Are you all missing?"

Professor A put away his phone in disappointment and walked towards the laboratory with the pile of materials in his arms.

Colleagues also went on vacation, and Professor A was the only one left in the laboratory, and after throwing a pile of materials on the ground, he sat on the sofa and gasped for breath.

"The old mistake is again! Alas! ”

Professor A sighed softly, his hands and feet trembling slightly, and he was really moved to think of the troubles he caused when he was young, which made him miserable now.

More than 30 years ago, when Professor A was still an undergraduate student, in order to be able to get ahead as soon as possible, he did not hesitate to risk his life to run in various harsh environments, and finally caused a disease.

At that time, Professor A thought that only by becoming a human being could he be happy in life, so he put all his energy into research, so that he still failed to find his other half.

In fact, there were many girls who pursued Professor A at the beginning, and some of them had very superior conditions, but Professor A was too persistent in scientific research and ignored them.

"Alas!"

Professor A sighed again, remembering all kinds of past events, he regretted it a little, he had been accompanied by Duan Pingsi for the past two years, he didn't feel anything, but after not seeing Duan Pingsi for many days, he suddenly felt that something was missing in his life.

Loneliness, he feels lonely now.

"Come out, stop hiding!"

Professor Ah suddenly shouted into the laboratory, and then a man in black came out of it, also holding a dagger in his hand, as if these men in black could only use daggers.

"How did you know I was in?"

The man in black looked at Professor A in astonishment, he was confident that he had been careful enough, but he didn't expect to be discovered by Professor A, this was the first time he had been discovered in advance.

"There is a sentence you must know, the magic is one foot high and one foot high!"

Professor A got up and walked to the window, looking out the window coldly, as if he didn't bother to look at the man in black at all.

"Haha!" The man in black laughed, "How do you know what Tao is and what is demon?" Are you the Tao, and I am the devil? It's ridiculous! ”

"That's nature!" Professor A snorted coldly, still looking out the window.

"If everyone is as hypocritical as you, wouldn't this universe be boring!"

The man in black swaggered over and sat down on the sofa where Professor A had sitting, with his short legs on his long legs and his legs on his feet, and a sharp dagger resting on his knees.

Professor A was not surprised by the behavior of the man in black, but said: "My Tao is to protect all mankind, but your Tao is to destroy all mankind, and it is clear who is good and who is evil!" ”

"And to protect all of humanity? Don't be funny, they are ruthless and unjust, they will trample you under your feet at any time, what is there to protect such a human being, and how can you protect it? The man in black chuckled.

"I can't do it alone, but there are thousands of people, and the power of human beings is endless, and countless historical facts are enough to prove this!" Not to be outdone, Professor A is not to be outdone.

"The facts? If you tell them the facts, you will end up like Professor Gao, who has proven that no one will believe the facts, how sad! ”

The man in black picked up and put down the dagger, repeating the same action over and over again, and his dark eyes stared at the tall figure in front of the window all the time.

"I don't accept your threats, if you want to kill or kill as you please, just ask you to use your true face to deal with me, don't hide it all day long!"

Professor Ah turned around and looked at the man in black, his hands and feet still trembling.

"If I wanted to kill you, I would have done it a long time ago, why wait until now, although you are a bit pedantic, but after all, you are still open in your heart, and besides, it will be of some use to us!"

The man in black said and put away his dagger.

"Don't try to threaten anyone with me!" Professor A snorted coldly.

"That person disappeared out of thin air, you probably know this, who else will have this ability except you?"

"I don't know, I don't have the ability to do this!"

"Don't push me!"

The man in black glared angrily at Professor A, he didn't expect the other party to be so stubborn, it seemed that it would not work if he didn't show some skills, and his right hand had unconsciously grasped the hilt of the knife.

The air in the laboratory suddenly froze, and Professor A felt the aggressive aura from the other party, but he just stood there quietly, he was indeed not afraid of threats.

"Hahaha! I don't believe he can hide for the rest of his life, I have time. The man in black laughed, and he didn't take out the dagger again.

"Please!" Professor A also put on a posture of sending off guests.

"I'll come again, I won't spare you easily next time!" The man in black swaggered out.

"Wait!" Professor Ah shouted at the back of the man in black.

"Huh! Are you going to tell me to stay and kill you? The man in black turned to look at Professor A, holding the dagger and looking around very vigilantly, before retracting the dagger after making sure that there was no one else.

"Next time you come, please show your true face, the evil devil will not dare to show his true face, if you are not......"

"Humph!"

The man in black had disappeared into the doorway, and Professor Ah breathed a long sigh of relief.
