Movable type printing is undoubtedly the biggest gain of Li Xiaogong's trip to Shandong. After receiving Li Chengqian's promise of non-proliferation technology within two years, the old man no longer had the heart to hang out with Li Chengqian, so when Li Chengqian and his entourage returned to the manor, it was not even noon.

The original sunshine assassin Kuroko has become much more gloomy, and his gaze makes people feel cold, and Li Xiaogong almost didn't recognize him when he saw him.

"Got it?" Looking at the sunspot who was following behind Wu Chen, Li Chengqian said with a light smile.

"It's much worse, I'm just a rookie without actual combat." Wu Chen pursed his lips and glanced at the sunspot behind him and said.

"What did you let Wu Chen teach? Don't waste a good child. Li Xiaogong looked at the sunspot for a long time, and said to Li Chengqian in confusion.

"Nothing, just some tricks." Li Chengqian said lightly.

Unexpectedly, Li Chengqian's brief statement made Li Xiaogong even more curious, and he couldn't help but ask what the methods were, and finally asked Wu Chen anxiously, so he said: "It's how to poison, how to kill with one blow, how to make people lose the ability to resist, and all kinds of torture methods." ”

"Oh, I understand when you say that." Li Xiaogong nodded in understanding, but ignored the trace of fear in Kuroko's eyes.

Then a few people chatted a few more words, and Li Xiaogong hurriedly left the hall and ran to arrange for people to go back to Chang'an to prepare for the printing house. This time he came in a hurry, and he didn't bring any business manpower, so he had to go back to find someone.

When Li Xiaogong walked away without a shadow, Heizi hesitated and said, "Your Highness, why did you choose me?" Wu Chen is far more professional than me. ”

"Because he lacks something in him, he can only be a guard, not a killer." Li Chengqian didn't notice the ambiguity in his words, and said to himself.

As a result, as soon as Li Chengqian's words fell, Wu Chen hurriedly yelled at the sunspot who had been aiming at him with a white face: "Bastard, where are you looking?" Lao Tzu is a man, and he lacks nothing. ”

Although Heizi was older than Wu Chen, under the pressure of Wu Chen's gaze, he could only say aggrievedly: "It was His Highness who said it." ”

There is no way, try your best to pass the cellar torture, the sunspot has been completely psychologically shadowed by Wu Chen's technique, as long as he sees this goods, he will feel unnaturally empty.

Feeling Wu Chen's aggrieved gaze, Li Chengqian couldn't help but smile and explained to Heizi: "You want to be crooked, what he lacks is the ability to integrate into ordinary people at any time, not that he lacks a part of his body, and this palace can prove it for him." ”

As a result, Wu Chen felt even more aggrieved, and he couldn't wait to take out the guy on the spot for everyone to see, because Li Chengqian's explanation that wanted to cover up was of no other use than to make people more suspicious.

But after some laughter, it undoubtedly brought the relationship between everyone a lot closer, and Heizi himself felt a lot more relaxed, and after thinking about it, he asked Li Chengqian: "Your Highness, do you want me to follow the man in black?" ”

"No, I want you to understand the composition of this organization, who the members are, how they relate to each other, everything, but don't be surprised." At the mention of the man in black, Li Chengqian regained his seriousness and said.

"Your Highness, can I know why they are dealing with you?" Kuroko asked after a moment of silence.

The young sunspot still has the dream of fighting the sword and punishing the evil in his heart, although he has the identity of an assassin, but in his heart, he has always thought that he is a righteous assassin.

Therefore, Heizi is very worried about whether he will do something like a tiger if he follows Li Chengqian, so it will violate his own principles of being a man, and if it causes bad consequences, it will be a hundred deaths.

"This is something you need to look into." Li Chengqian saw a trace of persistence in the eyes of the sunspot, paused and added: "Don't worry, this palace is still the same sentence, if you want to kill people, you won't use assassins." ”

"Well, Kuroko knows, but if Kuroko finds out that it is His Highness's problem, I hope His Highness will not blame Kuroko for saying goodbye." As an aspiring Assassin, Kuroko thought it would be best to talk before going on a mission.

"This palace does not restrict your freedom, you can leave whenever you want." Li Chengqian said with a smile. Originally, there was no sunspot in his plan, so Li Chengqian didn't care if Kuroko betrayed or not.

"Your Highness, I always feel worried about this guy, why don't you kill him?" Watching Heizi leave, Wu Chen stood beside Li Chengqian and said.

"If you don't want to be a bodyguard for the rest of your life, then don't always think about fighting and killing. You know, everyone will have their own use, the difference is only whether you will use it or not. Li Chengqian looked at the direction in which the sunspot disappeared and muttered in his mouth.

"Alright, don't think about it, tell me how that guy is?" Gently kicking the thoughtful Wu Chen, Li Chengqian asked.

"Dead." Wu Chen replied without thinking about it.

"Dead? What's going on? Isn't it okay in the morning? Li Chengqian asked suspiciously.

"Kuroko and I tried the method you taught to cut blood vessels, and he really scared himself to death." Wu Chen followed Li Chengqian's example, shrugged his shoulders and said.

"Cutting blood vessels?" A trace of confusion flashed in Li Chengqian's eyes, and then he quickly thought of what Wu Chen said, and asked with a glare, "Did you really experiment?" ”

When he was still in Kaifeng Mansion, Li Chengqian had inadvertently mentioned a psychological projection to Wu Chen.

The idea is to blindfold a person, preserve hearing, find something to scratch at the location of their artery, and then get some water to put next to it, mimicking the sound of blood dripping.

Then there are some simple psychological cues, such as telling the victim that your blood is dripping, and it will be a long time before you will die.

Then in about an hour, this person will scare himself to death because of his imagination.

Wu Chen didn't believe it at the time, thinking that Li Chengqian was deceiving people.

This time, he caught the young guy and used one night to get useful information, and inadvertently Wu Chen remembered the 'psychological projection' mentioned in the chat with Li Chengqian.

So this thing teamed up with the two of them to make such an experiment with the young man, and then ...... The boy died.

"Well, but Kuroko seems to have been scared too, and he looked at me like a ghost at the time." Wu Chen nodded, a little gloating when he mentioned the sunspot, and there was no guilt at all in his words that he had just killed someone.

Moreover, in addition to looking at Wu Chen quite helplessly, Li Chengqian didn't know what to say. The people around him are becoming more and more perverted, and it seems that there are not many people who are normal, which makes Li Chengqian feel that he is a 'Tang tumor'.
