In the hallway, Bruce walked quickly to the office with a stack of papers, knowing that if he was two minutes late, today's papers would be difficult to pass.

Bruce stood in front of the door and knocked on the door, but the sound from the room was the sound of high heels, and it was Anna who taught mathematics who opened the door, and Bruce glanced into the room and said, "Isn't Professor Schiller here?"

"He has something to do this afternoon, are you here to look at his papers?" Anna glanced at her watch and said, "You may have to come back after seven o'clock in the evening, and by then, he should come back to pick up something."

Bruce froze, and he said, "After seven? But it's only two o'clock in the afternoon, where has Professor Schiller gone?"

Anna shook her head and said, "I don't know, after he finished eating at noon, he hurried back to get two books on basic psychology, and then left, or why don't you go to the library or something like that to look for him?"

"Library?" Bruce said in surprise, but looking at Anna's expression, he didn't ask more, but took the paper and turned away.

Standing downstairs in the office building, Bruce felt a little lost, and he suddenly realized that he really didn't know where to find Schiller.

As far as he knew, Schiller usually didn't go to the library, because the library at Gotham University was relatively old, there were few seats, and even if the librarians were strict, it was inevitably a little noisy, and Schiller usually wrote papers in his own estate.

After all, Gotham University does not have a president, no one will check attendance, and after the morning and afternoon classes, even if these professors want to leave, no one will stop them, so the professors at Gotham University are very free, and if there are no classes in the afternoon, they can go home.

Bruce thought about it, then came to the parking lot, got in the car, and drove to the Rodriguez manor, and when he came to the manor, it was Merkel who opened the door for him, and Merkel was a little surprised by Bruce's arrival, and he said, "Mr. Wayne? What is the wind that has brought you here?"

"I'm coming to Professor Schiller, is he there?" Bruce asked.

Merkel was stunned for a moment and said, "No, he has been living in the school recently, and he hasn't been back for a few days, you can go to the school and look for it."

Bruce just wanted to say that he was from school, but after thinking about it, he didn't say anything more, got in the car, and went back to school.

Then he went to the teacher's dormitory, but the dormitory manager told him that Schiller had gone out in the morning and had not returned to the dormitory for the rest of the day, and then went to the classroom and laboratory building where psychology classes were usually held, but Schiller was not found.

Eventually, Bruce chooses to call Gordon and ask him if he's seen Schiller, and when he gets the answer yes or no, Bruce starts to feel a headache.

If there is still any iron law in Gotham, it is that Schiller is quiet and must be a demon.

All of this was very unusual, and in the past few days, Bruce had to be vigilant every minute, for fear of missing Schiller's call, and if that really happened, he would not have to think about passing today's paper, and it was very likely that he would be called back and rewritten.

The process of discussing papers is often measured in hours, often starting before lunch time is completely over, and until dinner time, Schiller also expressed great dissatisfaction with Bruce's need to eat, and even suggested that he get a set of life-sustaining armor to reduce the time required to solve physiological needs.

After racing against the clock for so long, the time saved may not be as long as the time wasted in this afternoon, Bruce does not think that Schiller will disappear for no reason, and it is more likely that he has encountered more troublesome things, so he has to solve them.

But what could it be that could make Schiller feel in trouble?

Thinking of this, Bruce had to raise his vigilance, if there was really one thing that the professor had to spend hours to solve when he desperately needed time, then I am afraid, it could threaten the life and death of Gotham and even the entire East Coast.

Thinking of this, Bruce immediately drove to the Batcave and activated the surveillance system of his subordinates in Gotham.

Batman's surveillance is everywhere in Gotham

After several iterations of technology, the camera became very hard, difficult to destroy, and more stealthy, and the whole of Gotham City was under Batman's watch.

Before turning on the screens, Bruce wanted to be able to see Schiller's shadow in those screens, as things could get more troublesome if Schiller wasn't in Gotham City.

But when he turned on the screen, before he found Schiller, Bruce first spotted another uninvited guest, because his dress was too strange, so he immediately attracted Bruce's attention.

The man was dressed in a black tights with a green cloak, a flute in his hand, and a gun hanging from his lap.

At this time, the man was on a street not far from Gotham University, and Bruce saw that he seemed to have just come out of a video store with two records in his hands.

Bruce wanted to investigate, but now, the more important thing was to find Schiller's location.

He continued to look at the surveillance screen, and then realized that Schiller had actually been at Gotham University all along, but in an empty classroom on the top floor of the school building, sitting across from him was Jason Todd, the kid who stole the bruce tires.

Zooming in on the surveillance perspective, Bruce found that Schiller was holding a book on basic psychology and pointing to the text on it to read to Jason, who was engrossed in listening.

Just as Bruce was about to listen to what Schiller was talking about, something unusual on another surveillance screen caught Bruce's attention.

The strange man in the green hood attacked a gang member in the street, or it can't be said to be an attack, and the strange man took out a flute and played it, and the gang members who were across the street from him suddenly danced.

But the next second, he was surrounded by heavily armed gangsters, and Bruce quickly stood up, changed into Batman's outfit, and rushed to the scene as fast as he could.

Fortunately, the strange man still had one breath left, and he only had seven or eight more holes in his body.

Batman is pretty sure that he's an outsider, because a local wouldn't stand on the street at the junction of three gangsters' turf in fancy clothes, as if he was holding a loudspeaker and shouting "here's a good target for gun practice".

Taking advantage of the gangster's lack of attention, Batman dragged the weirdo into the car, then took him to the Batcave, gave him a simple operation, and then bandaged it and waited for him to wake up.

Dozens of minutes later, the strange man in the green hood finally woke up, in the haze, he saw Batman's face, instinctively turned over and wanted to run, but the severe pain made him unable to get up, he heard Batman ask:

"Who are you? What are you doing in Gotham?"

As soon as the man in the green hood was about to speak, Batman picked up the scalpel from his side and wiped it with paper, and the strange man in the green hood swallowed a mouthful of saliva and said, "You can call me Piper......

"What are you doing in Gotham?" Batman asked again.

"I...... I'm here for a trip......" As soon as the piper finished speaking, he saw a batrang land next to his ear, and he moved his head to the side, and said, "Well, I'm here to save people."

"Save whom?"

"That's it...... Mirror Masters, them."

"Mirror Master?" Batman's eyes widened, a look of suspicion, and then he asked, "Who else?"

"And ...... And Captain Cold." The Pied Piper gasped, the pain made his mind a little dazed, and then he was frightened by Batman, and he began to talk freely:

"Savage, Great King, he wanted Gotham as a foothold on the East Coast, and he sent Master Mirror and Captain Cold to explore here, but both of them were trapped, trapped in Gotham University, where there was a professor and they couldn't deal with it......

"Savage got their distress signal and asked me to come and pick them up, and I wanted to go straight to Gotham University, but the video store next door happened to play the music I liked, so I went in and bought two records......

Batman looked at the flute next to him, and he said, "You can get through

Use this flute to control others?"

"Yes." The Piper said, "That's why I'm called the Piper......

"Tell me more about the Great King."

While Batman was pressing to blow the enemy's information, Schiller was explaining the basic concepts of psychology to Jason in the empty classroom, saying:

「…… Of course, this subject won't answer all your questions, but you can also take philosophy and social engineering, and some of the subject will cover economics, but these subjects will be different from the techniques you have learned before."

"They don't let you learn a particular craft, it's more like a collection of human thinking, which has disadvantages and advantages compared to some technical professions."

"If you're not sure if you like the courses, you can read them first." Schiller handed Jason several books, in addition to basic psychological knowledge, as well as introductory textbooks on philosophy and economics.

Jason was holding the book on basic psychology that Schiller had just handed him. He was looking at the economics book he had just borrowed from the library, and Schiller was reading it.

The atmosphere in the room fell silent, and after a while, Jason rubbed his eyes, let out a long breath and said, "It's really amazing, I never thought it would be able to explain some of people's thoughts like that......

Schiller took the book in his hand and said, "Where do you see? Have you read this part?"

Jason glanced at where Schiller was pointing, and he said, "I've finished reading it, and I've finished reading the next unit."

"The latter unit ......" Schiller flipped back, and he found that the latter section took up a full twelve pages, and, unlike the previous one, which simply expounded basic concepts, there was some content from brain science.

Schiller frowned, looked at Jason and asked, "Do you understand everything you have before?"

Jason hesitated for a moment and said, "I'm not sure, but at least. I memorized them all."

Schiller's eyes widened and asked, "What did you say?" You've memorized them all???

Jason nodded, and began to recite from the beginning.

As we all know, in fact, the tone and rhythm of memorizing texts can see whether the other party really understands these contents, if it is rote memorization or unproficient, there will be problems with the broken sentences of some sentences, and you need to pause in the middle to think.

But Jason didn't have this problem at all, he memorized it very fluently, and Schiller, who had already told it to many grade students several times, knew that he had not only memorized it, but understood most of it.

With Jason's endorsement, Schiller's eyes became brighter and brighter, but at this moment, the phone by the podium suddenly rang.

Jason was startled, the endorsement stopped, Schiller stood up, walked over to the phone, picked it up, and said:

"Hey? Who? …… Bruce?"

"Who's Bruce?"
