Damian is not tall and has a very thin build, not only because of his age, but also because of the rigorous exercise he insists on on a daily basis. The amount of exercise is even more than that of many adult killers, and he cannot gain weight even if he wants to.
He stood in front of Deathstroke, raising his head and looking at the other person's face, and the other person looked at him very kindly.
Suddenly, Su Ming hugged Damian in his arms, put his head on his belly, and gently touched the back of Damian's head.
Da Mi suddenly became alert and wanted to struggle, but Su Ming had already let go of him.
"???"
What's going on? Why would the other party do such an action?
He looked at the death knell from another world in front of him in bewilderment, but the other person's helmet had risen again, covering all his expressions, and his voice returned to a demonic whisper.
"Come on, I'll teach you how to solve the case." With that said, Su Ming turned and left.
Damian touched the back of his head to make sure that someone had not planted a bomb, but what was the purpose of the death knell? It was weird.
Even though he was thinking about it, he emphasized: "Batman taught me."
Deathstroke turned back and looked at him with his red single eye, which looked particularly dazzling in the darkness: "He is him, I am me, our reasoning methods are different."
"Really?" Damian agreed. He was still thinking about Deathstroke's abnormal behavior, and the warm feeling seemed to still be above his head.
"I wonder if Batman has taught you systematically, what types of reasoning are there?" Su Ming motioned to Damian's friends to come over. The clues were right in front of them.
Damian touched his nose, feeling very uncomfortable: "Batman generally doesn't need too much reasoning, because everything here is under surveillance."
"It's a pity that after the flood, all the monitoring equipment was scrapped. This time he will be in trouble again."
Su Ming smiled and reinstalled all the cameras in Gotham. This was not a waste of money. Usually only he and Ah Fu were busy with such secretive things. He would not trust it to others.
Damian nodded. Batman would not let him get involved in this matter. He would prevent other people in the family from knowing his surveillance position.
Su Ming did not say much on this topic, but talked about the business just now, and talked about logic knowledge:
"Logical reasoning is generally divided into five methods, namely the three-paragraph deduction method, the conjunction decomposition method, the chain deduction method, the comprehensive induction method, and the reductio ad absurdum refutation method."
"Well..." Damian nodded, but everyone else seemed a little absent-minded.
"The deductive method is a relatively well-known method. Sherlock Holmes, the most famous British detective, is a fan of the logical deduction method. It emphasizes the reasoning method of two property judgments connected by a common concept as the premise, and deducing another property judgment as the conclusion.
"
Su Ming didn't care whether others heard it or not. Anyway, this play was for Damian to watch, whether others liked it or not, so he just looked at Damian's face and waited for his reaction.
Damian nodded. The logical deduction method is a very stable and accurate method. The chain of clues forms a triangle by deducing one from the other and attributing many clues to one point to arrive at the truth.
This is a method of solving crimes that requires detailed observation. Detectives who use this method often have powers of observation beyond ordinary people.
Seeing him nodding and looking like he was listening attentively, Su Ming smiled secretly, but soon became serious again and continued.
"Many people use the rebuttal method of reductio ad absurdum, which is a method of thinking that demonstrates that the absurd conclusion of a proposition cannot be established, such as cases such as secret room murders and supernatural deaths. Often, more discoveries will be made by working backwards from the results. This
It requires not only a smart brain, but also a firm will and the belief that you have thought of everything, a method of reasoning that completely restores the criminal method."
"It sounds familiar, but this is not Batman's method." Damian pinched his chin and whispered.
Su Ming also pinched the chin of his mask and nodded towards Emiko who was staring at him. She seemed to be somewhat interested in this and started to listen.
"Batman is called the best detective in the world. In fact, this is just because he solves more cases. He is not good at reductio ad absurdum, but there are indeed people who are good at it... You probably don't know him, that person
It’s called Rorschach.”
"If all possibilities are eliminated, then even if the remaining possibility is impossible, it is still the truth...right?" Damian murmured.
"That's it." Su Ming nodded affirmatively, put his hand on Dami's shoulder and continued: "Batman most often uses the comprehensive induction method, which is a reasoning method that uses a large amount of individual knowledge as the premise to summarize a general conclusion.
That is, a comprehensive method that uses a large number of irrelevant clues to piece together relevant clues based on common sense.”
Da Mi seemed to be still immersed in thinking and didn't care about Su Ming's hand. He nodded: "Because he has a lot of information and a supercomputer in his hand, this is a very effective method."
Su Ming took the words and continued: "In fact, Brother Eye can also reason on its own. It uses the conjunction decomposition method. For example, the probability of a happening is 50%, and the probability of b happening is also 50%. Then when ab happens at the same time,
The possibility of causing a certain consequence is only 25%. Some people with strong brains can also do it manually, but it is similar to the exhaustive method of calculating and decrypting, and finally finding a higher percentage among a bunch of numbers."
"It seems to be the most scientific, but in fact it is the most inaccurate..." Damian took a breath, and Su Ming could feel his chest swelling under his palms.
Su Ming nodded, with some helplessness in his tone: "Yes, because this is a calculation, but it cannot calculate an important variable, which is the human heart. People's behavior can be summarized based on habits, but the thoughts in people's hearts,
It cannot be explained mathematically."
Billy wiped his mouth. He had just poured a large bottle of carbonated drink into his mouth and threw the empty bottle out the door: "For example, sometimes I eat hamburgers and sometimes hot dogs for breakfast. Then in mathematical logic, I choose two breakfasts.
The probabilities are all percentages, but I actually want to eat fried dough sticks and soy milk, so I may suddenly change my habits. This variable is unpredictable."
"That's it, and I'm sure you're lying. You don't have the habit of eating breakfast at all." Su Ming shook his head slightly at him.
The fat man smiled again and scratched his head stupidly.
Isn't it? He is a serious homebody. When he has no tasks, he plays computer games until midnight. When he wakes up, it is already the afternoon of the next day. What kind of breakfast is there?
"Then what is your reasoning method?" Damian brought back the topic, raised his head and looked at the people around him. It was the first time he was so close to the death knell, and he could even smell the blood on his armor.
Su Ming squatted down and drew a circle on the ground: "Because I am not a detective, so my need for the truth is not that strong. My method is the jumping puzzle method."
"Wait a minute, this doesn't seem to be among the five methods you mentioned before." Wally held his head and squatted down. Although his thinking speed was also very fast, he didn't like to study at all.
Didn't understand.
To be honest, Barry probably wouldn't be interested in these things, otherwise he would have been a policeman instead of an evidence examiner.
"That's right, otherwise how could I be the world's number one mercenary?"
Su Ming laughed from behind his mask, and took his hands off Damian's shoulders. After losing weight, Damian suddenly felt empty.
Crushing crossed his arms and turned his head to the side: "The wolf is the number one bounty hunter in the universe. What's the point of being number one on earth?"
"That's right, but does Baolang have something to do with you? Does he recognize you?" Su Ming sneered, and in a flash he was behind Crushing, holding her head in his hand: "I will bully you today.
Now, will he come to settle accounts with me for this?"
"You...uh!"
Although Crushing is pretty good, in terms of strength and martial arts, he is still only at the junior level, and he can't get away no matter how hard he struggles.
"He doesn't dare because he is not my opponent, haha..."
Su Ming rubbed the little girl's hair wildly. She was a pretty girl. She had tattoos, smoked and drank, and she also had a killer style. She must be educated well.
Although the violent wolf is strong, its biggest weakness is that it has no magic resistance. This is completely restrained by Su Ming in DC. Is the Supreme Mage joking?
"Don't touch her, come at me if you want to touch her head!" Damian growled in a low voice, his face expressionless, and he didn't know what he was thinking.
Emiko glanced at Da Mi after hearing this, and moved her feet to the side without leaving a trace. There was a little more disgust in her eyes when she looked at Da Mi, as if she had discovered something.
Su Mingcai didn't care so much. He flew back calmly, put his hand on Da Mi's head, and touched it twice with satisfaction.
"Let's get down to business and stop teasing them." Damian's tone sounded hopeless, but he didn't try to get rid of the big hand.
"Well, my reasoning method is more like playing a jigsaw puzzle. First, I clarify my purpose, and then go for it. It's more like starting from a central point and linking different clues."
Su Ming looked at the corner of the room, and there seemed to be some changes there.
Damian blinked: "Isn't this a common method used by dirty policemen to frame people? Piece together the chain of evidence."
"Of course it's different. If you only weave a chain of clues, it's naturally weak. It's right to say it's a frame-up..."
Su Ming gently dusted his armor with the back of his hand, as if brushing away non-existent dust, and continued speaking softly.
"But if you can compile hundreds of evidence chains and put forward thousands of hypotheses at the same time, then whether it is a conjecture or a hypothesis, as long as you exclude chains that go in different directions, exclude those that are inconsistent with common sense, and exclude those that are too similar,
Then eliminate the unachievable and flexibly use the above five reasoning methods to connect the remaining irrefutable dots and fill in the missing ironclad evidence, then you will find that the truth is right in front of you!"
"!!!"
Damian was surprised at first, and then looked bitter. This is not a task that normal humans can complete. Only Brainiac can use this to solve the case, right?
For the first time, Damian developed a little admiration for the alien Deathstroke, who seemed to be better at solving crimes than Batman...
