On the way back, Lin Dong thought he had to search for every clue in his memory to find Qin Yao's strangeness.

But it doesn't need to be.

Almost at the moment when he thought this man was strange, everything suddenly became clear:

Three days ago.

Lin Dong was like the same as before, and after class, he came to Qin Yao's office, brought the homework at the desk and found a corner to review it.

At this time, Qin Yao was lying barefoot on the sofa in a daze.

Lin Dong’s impression of him is probably a bastard who won the title of "Nature".

The most confused thing is that Qin Yao published that the thesis when he was studying for a doctorate at the age of 26.

It is said that he worked with a foreign team behind his back and became a tie for the first author.

From then on, the master and apprentice changed his position, and he called his mentor Lao Huang and the teacher called him Teacher Qin.

Afterwards, Qin Yao rushed up at the speed of a rocket, and at the age of 31, he became an associate professor, and at the same time he mastered considerable resources and power.

But it just doesn't live.

When teaching, you can also choose the easiest undergraduate marginal subjects.

Don't judge your own homework.

I don't even give the test papers by myself.

But he still has meaning.

After all, people are more energetic and very good at fooling him, so the school doesn't mind giving him any support.

However, Qin Yao became more and more depressed this semester and refused all academic activities, so he was too lazy to even fool him.

At this moment, he was lying on the sofa, swaying the wine bottle and muttering: "If the people in the world are divided into wolves and sheep, you should be a sheep, Lin Dong."

"Yes." Lin Dong muttered, "Why did I also judge the homework of Class 4? Sheep can't be so fucked like this, Teacher Qin."

"Oh, then don't judge it, throw it away." Qin Yao laughed and tilted his head to look at Lin Dongdao, "You're here, please think of a question for me."

"You can't even figure it out, I'll just forget it."

"Let's think about it together, it's very interesting." Qin Yao sat up with his couch and raised his eyebrows, "I still have an academic consultation fee, just use it on you. Is 1,000 yuan in half an hour enough?"

Lin Dong'er glared at the eye and immediately threw away his homework: "What's the money? It's my honor to discuss it with Teacher Qin."

"Okay, then I'll ask a question." Qin Yao leaned over and smiled and gestured:

"Suppose there is a society, composed of 1,000 sheep."

"Suddenly one day, a sheep turned into a wolf."

"But his appearance is still like a sheep."

"What should I do next?"

"Discussed from the perspective of sheep and the perspective of wolf."

Lin Dong immediately replied:

"The sheep should unite to find the wolf and get rid of it."

"Wolfs should hide themselves and try not to eat sheep as much as possible. Even if they eat, don't leave any clues."

Qin Yao nodded and said, "Okay, then next, more sheep will turn into wolves, maybe 5, then what?"

Lin Dong thought for a while and replied, "It's the same as before."

"Where are 10?" Qin Yao asked again.

"Then... the sheep can almost wait to die." Lin Dong shook his head with his lips pursed, "10 wolves, no matter how hard the sheep fights, they can't win."

"That's it?" Qin Yao leaned on the sofa with some disappointment.

"What about that?"

Qin Yao raised his head and sighed:

"Otherwise, don't be so stiff."

“Be more humanistic.”

"Try to take 'humanity' into consideration."

"Think about it, those wolves were sheep before, right?"

"Their parents, wives and children are still sheep, right?"

"Will there be some kind-hearted wolf joining the sheep's side and trying to establish a harmonious society where sheep and wolf coexist?"

After thinking for a while, Lin Dong shook his head and said, "Wolfs always want to eat sheep."

"Yes..." Qin Yao looked at the ceiling emptyly:

"There must be more malicious wolves than the well-intentioned wolves."

"As long as a wolf eats the sheep, the flock will panic and be hostile to the wolf."

"A good-willed wolf will also begin to hate the ignorant sheep if it is let down."

"Then, there is a cycle of hatred."

"I'm just thinking, if... a miracle happens."

"A good-willed wolf and sheep will destroy all the malicious wolf?"

Lin Dong swallowed and said, "Teacher Qin, isn't it a bit unscientific to use the word miracle here?"

"Suppose, just assumption." Qin Yao looked at Lin Dongdao unwillingly, beggingly, "If good will defeat malice, will there be a harmonious society?"

"Maybe it can be maintained for a while." Lin Dong said regretfully, "But it won't take long before a wolf will start eating sheep again, just like no matter how severe the punishment is, it cannot stop the crime. Then, there is a cycle of hatred again until it collapses. How to see, the society where sheep and wolf coexist is simply unstable, and one side must destroy the other."

"You're saying this very absolutely." Qin Yao smiled dryly, smiling a little sadly, "Sometimes, there is at least one stable structure in the society where sheep and wolf coexist."

"Um?"

Lin Dong thought for a moment and the answer came to his mind.

Indeed, there is a stable structure.

Extremely simple and clear.

That is, the wolf controls this society.

Then go to raise sheep.

In this way, you will never have to eat.

But, in this society.

Are sheep still considered citizens?

Thinking of this, Lin Dong felt inexplicably cold, so he had to turn on his homework again to seek warmth, and waved his hand and said, "This question is so weird, please consult something else."

Qin Yao smiled, took a sip of the wine bottle, and said in a deeper tone:

"There is nothing else, but this one is interesting."

"Come on, start over."

"It's still this model, back to the beginning."

"The first sheep that turned into a wolf was not produced for no reason, but drank a potion."

"There are 10 bottles of this medicine in total and will be distributed randomly."

"The first 5 bottles have been drunk."

"Now there is a sheep named Lin Dong, and I got the 6th bottle."

"What should he do?"

Lin Dong swallowed and spitted: "Why are you so bored..."

Qin Yao smiled strangely and said, "I'm the last question, I'll pay you a consultation fee after answering it."

"This is not a problem. You have to drink it no matter how you think about it." Lin Dong nodded while judging homework, "No matter whether this sheep named Lin Dong is kind or malicious, whether you strive to protect yourself or realize your ambitions, you should drink it. Only when you drink it will have a choice, only when you drink it will have strength, and only when you drink it will have a future."

"That's what you think... well... it's quite consistent with him..." Qin Yao looked up at the ceiling silently and sighed:
Chapter completed!
