Both Lu Yan are real, so there is no need to distinguish between truth and falsehood, all that needs to be distinguished is which Lu Yan's body is hiding in the body of the pretender, only in this way can the trouble be avoided later.

The problem is that the two Lu Yan are the same, and they both think that they are real, and even they themselves can't tell the truth from the fake, and it is even more impossible for others.

"What is your way to tell the difference?" Liang Chen was completely dumbfounded, no matter how experienced he was in criminal investigation, he couldn't think of any way to face such a situation.

"There is a way, but I'm afraid it's useless, we must take into account the IQ of the pretender, the method we can think of, he may have thought of it, and take measures as soon as possible. Sun An also felt embarrassed, when fighting, no matter how strong the enemy is, he can find a way to defeat it, because people will make mistakes, and there will always be flaws, but this kind of enemy is different, passively defending, and slowly patching up the defense loopholes, just like a turtle retracting into its shell, even a tiger can't bite it.

"You have to try," Sun Xiuming said, "how can you know if it will work if you don't try." ”

Sun An nodded, took out a tea knife and said, "I think so too, so let's try it." ”

He crouched down and pressed the blade to the back of one of Lu Yan's wrists.

"What do you want to do?" Liang Chen asked curiously.

"Didn't I say just now, if the state will be imitated, then the physical condition of the original Lu Yan will be reflected on the pirated Lu Yan, scratch two cuts to try, if this Lu Yan is scratched, the other Lu Yan is not, then this is fake, if this Lu Yan is scratched, and the other Lu Yan is also injured, then this is true, and vice versa. Sun An said as he scratched a shallow wound on the back of Lu Yan's wrist.

Blood spilled out, and a very conspicuous red line appeared on the skin, such a wound was really nothing to a policeman, and even the scar would not be left.

The three of them immediately looked at the other Lu Yan and saw the same, very displayed red line on the back of her wrist.

Lu Yan didn't feel the pain, she couldn't turn her head, she didn't know what Sun An had done, she was just nervous, waiting for the result.

Liang Chen and Sun Xiuming were also nervous, if Sun An's guess was correct, then the Lu Yan on the left who he started was real, and the one on the right was imitated, but is it really that simple?

Considering the IQ of the pretender, it is impossible for the two Lu Yan to distinguish the real from the fake so easily.

Sun An moved the knife to the back of Lu Yan's wrist on the right, and with a slight stroke, another red line appeared, forming an "X" with the previous one.

"If the fork is bigger and black, you can raise your arms with Luffy. Sun An looked at his masterpiece with satisfaction.

Liang Chen and Sun Xiuming looked at Lu Yan on the left again, and saw an identical fork on the back of her wrist.

"Look, I'll just say it's useless, this imitation is...... Two-way. Sun An put away the tea knife and stood up, and began to think of new methods.

Two-way imitation, Liang Chen and Sun Xiuming both heard this word for the first time, but it is not difficult to understand that the imitator and the imitator have the same situation, and it is impossible to distinguish the true from the false through this method.

They couldn't think of any more ways to do it at all.

"Then what about killing one of them?" Sun An still has a way, and he naturally takes the extreme route.

"What if...... What if you make the wrong choice?What if you kill the real Lu Yan?" Liang Chen didn't want Sun An to try like this, although he knew that Sun An could bring Lu Yan back to life.

"Uh...... Actually, I thought that the 50% chance was good enough, at least much better than doing multiple-choice questions on the exam, but unfortunately I was not very lucky, I seemed to ...... I'm not sure, but it's always okay to do it again, so let's wait. Sun An took the tea knife and said helplessly.

This sounded weird, Liang Chen and Sun Xiuming both frowned, glanced at each other, and didn't understand what Sun An was talking about.

At this moment, the two unable Lu Yan sat up at the same time, raised their hands and pinched Sun An's neck.

Liang Chen and Sun Xiuming were both taken aback, stunned in place, Sun An jumped back violently, the corners of his mouth rose, and after landing on the ground, he said lightly: "Hey...... And so it was. ”

The two Lu Yan didn't wait for him to finish, and at the same time stood up and threw themselves at him, their movements were exactly the same, without the slightest delay.

Sun An retreated again, bumped into Liang Chen and Sun Xiuming, and dodged Lu Yan's pounce, but after they landed, they pounced on her again.

Liang Chen and Sun Xiuming were hit hard, but they finally came back to their senses, and the two of them rushed out at the same time, hugged Lu Yan and knocked her down, lying on the ground and strangling her.

"You're just waiting for me to do this kind of test, right? Kill one Lu Yan, and if you find out that the killing is wrong, I will use the ability, and then kill the other, what you want is the time period when my ability cools down, and when you are sure that I have used the ability, you will suddenly come and kill me." Sun An played with the tea knife, looked down at the two Lu Yan and said.

He didn't kill Lu Yan, nor did he commit suicide, but he just said it as if he had committed suicide, which led the pretender to be fooled, and the plan succeeded, but his goal was not achieved.

Sun An thinks that the pretender must have a very powerful killing, the pretender's ability needs to pay a lot of price, during the imitation, if the imitated object dies, he is afraid that he will also die, the stronger the ability, the greater the cost, to pay such a big price, his ability should be very strong, even if the imitated object dies, he will not die, he will inevitably be seriously injured.

It is not difficult to guess that the pretender wants to kill him while his skill is cooling, and it is quite easy to lure the pretender into being fooled, just misleading the language, but the pretender's reaction is unexpectedly weak, close to the battle, two Lu Yan want to kill him? I'm afraid ten more will not be enough.

There is no explosiveness, no lethality, with the IQ of the pretender, it is impossible to make such an attack, and after falling into Sun An's situation, he should not use such a bad attack, at least grab a gun or something.

Unless...... He was also testing whether Sun An was really dead.

If you want to disguise, you must always be careful, if you are not careful, you will be discovered, only people with very good brains and very cautious can disguise themselves as another person, accustomed to caution, the pretender is naturally step by step, and will not use a big move at the beginning.

Sun An saw that the corners of Lu Yan's mouth were also curled, as if he was laughing at him, instead of the person he had fallen for, and then, the two Lu Yan did not move again, and collapsed in the arms of Liang Chen and Sun Xiuming.

"Strange, how did their rope break?" Liang Chen felt that Lu Yan in his arms was no longer struggling, tried to let go of her, put her back on the ground, and looked at the rope next to him and said.

Both Lu Yan were tied up, but when the two Lu Yan got up to attack Sun An, the rope slipped from them, as if they were not tied at all.

"That's probably his biggest secret, his real means of attack. Sun An said in a deep voice.
