"Look, there's no need to review now, and there are no guests, so I'm so idle, why don't you teach me some simple things first, such as the keys of the piano."

Faced with Duan Zilian's doubts, Xu Ying explained.

"Hmm...... Okay. Anyway, I have nothing to do now, so Duan Zilian agreed, and first taught Xu Ying to know the keys of the piano.

"Generally speaking, a piano has eighty-eight keys, of which fifty-two are white and thirty-six are ...... black."

Xu Ying listened from the sidelines, as long as she learned to play the piano, she would be able to have more common topics with Duan Zilian.

With such an idea, she listened very carefully, and asked Duan Zilian some questions from time to time.

After more than half an hour, Duan Zilian finished teaching and let Xu Ying leave.

After all, he just taught Xu Ying to learn to distinguish the keys of the piano, which was relatively simple and was quickly taught.

Next, he has to teach Xu Ying a lot of basic things, such as the timbre of each key, reading staves and a lot of specific operations, and only after Xu Ying has learned these things can it be regarded as an introduction.

However, Duan Zilian and Xu Ying are not in a hurry, on weekends, Xu Ying can learn a little a day.

It's just that she knows how to distinguish each key of the piano, and before leaving, Xu Ying glanced at Duan Zilian with worry in her eyes.

In the process of Duan Zilian's self-teaching, she could see that Duan Zilian's face was always full of thoughts, and she couldn't get rid of it.

She didn't know what Duan Zilian was worried about, but she was too embarrassed to ask, so she could only hold this doubt in her heart.

Looking at Li Nan, who was instructing Qian Meng to make coffee, she thought for a moment and walked over.

"Sakura, how's it going?"

On the way, Song Cheng looked at Xu Ying playfully with gossip on his face.

"I just learned how to distinguish the keys of the piano, what progress can I make in this little time?" Xu Ying glanced at Song Cheng a little helplessly, and continued to walk towards the bar.

"Brother Nan, can I ask you something?"

"Huh? What's up? Li Nan asked Qian Meng to continue making coffee, turned around, and looked at Xu Ying suspiciously.

"I feel like there is something on my mind, and it seems to be very important, I'm worried that he will be dead-headed, unable to think about it, etc., can you go and enlighten him?" As she spoke, Xu Ying looked back at Duan Zilian's back.

"Really?" Li Nan glanced at Duan Zilian, and then nodded.

"Okay, I'll talk about it later."

After speaking, Li Nan continued to teach Qian Meng to make coffee.

Among them, guests came in one after another, Xu Ying and Qian Meng went to entertain the guests, and Li Nan prepared coffee, drinks and desserts for them.

When the work was over, Li Nan wiped his hands and walked towards Duan Zilian.

At the same time, because he was thinking about Zheng Yulong's affairs, Duan Zilian couldn't concentrate, and when he was playing the piano, there was a mistake that shouldn't have happened, and he frowned slightly, so he stopped, intending to adjust his mentality first.

Suddenly, Duan Zilian felt a hand pat his shoulder, and at the same time, Li Nan's gentle voice came into his ears.

"What's wrong? It looks like you're not in a state, do you have something on your mind? ”

Duan Zilian shook his head: "No, Brother Nan, you think too much." ”

Li Nan patted the joke again

Shoulder: "Just stop pretending, you're acting so obviously." ”

"Really? Is it really that obvious? Duan Zilian smiled reluctantly.

Li Nan nodded: "Well, obviously, when you go out of society in the future, you have to learn to hide your inner emotions, of course, you don't have to think about these for the time being." ”

After a pause, he brought a chair over, sat next to Duan Zilian, and continued: "You have something to worry about, but you don't tell us, you don't want us to worry, right?" But you're only going to worry us more. ”

"You, everything is good, you just like to hold your worries in your heart, and when you encounter difficulties, you don't tell us, you always like to solve them yourself, you hold everything in your heart, it's easy to get sick."

"If you have troubles or difficulties, you can try to tell us as much as possible, don't be afraid to trouble us, maybe we can help you, right?"

After a long speech, Duan Zilian was silent, but he smiled bitterly in his heart.

Li Nan said it simply, he really wanted to find someone to tell him about the troubles in his heart, but he was afraid that others would not believe what he said.

Moreover, even if others believe it, it will not help much.

Can you still count on someone else to help deal with the xenomorphs?

Seeing that Duan Zilian was silent, Li Nan sighed: "I said so, can't you tell me about your troubles?" ”

"Let me guess what troubles you have at your age...... Do you have a girl you like, but you don't know how to confess it, so you're struggling here? ”

In the end, Li Nan said a joke.

Duan Zilian was amused by Li Nan's joke, and couldn't help but smile: "No, Brother Nan, where do you want to go, if only I had a girl I like." ”

Li Nan smiled: "Do you have a favorite girl at this age?" I don't believe it. ”

"Not really." Duan Zi spread his hands helplessly.

"Okay then."

Saying these three words, Li Nan gradually retracted his smile: "Since your worries are not this, then what are you worried about?" Can't you really tell me about it? ”

“……”

Putting away his smile, Duan Zilian was silent for a while, looked at Li Nan, sighed, nodded gently, and decided to tell Li Nan about the troubles in his heart.

Of course, he won't tell the truth, but in a different way.

"Hmm...... Actually, it's not a problem for me, it's just a problem that I can't figure out. ”

Seeing that Duan Zilian finally relented, Li Nan smiled slightly: "What's the problem?" ”

After thinking for a while, Duan Zilian slowly said: "I read a book late yesterday, in which the protagonist met an enemy, and that enemy did a lot of bad things and killed many people. ”

"However, that enemy is actually just a poor man who is controlled by the mastermind, and even his life is in the hands of the mastermind."

"Even his life has been manipulated by the mastermind behind the scenes, so the enemy can't resist at all, and the protagonist has no way to save him."

"In this case, for the sake of the overall situation, the protagonist can only fight that enemy, and even make him sacrifice."

"However, that person just wants to live, wants to live with his beloved, and if the protagonist defeats him completely, he will die,

Moreover, there will be people who will be sad about it, and the protagonist may feel guilty about it. ”

"So, I can't figure out whether it's right or wrong to break other people's wishes, sacrifice other people's lives, and make other people sad for the sake of the overall situation?"

"Is it really worth it?"

After saying so much, Duan Zilian finally said the troubles in his heart in disguise, and suddenly felt a sense of relief.

"So you're bothered by this kind of thing, huh?" Listening to Duan Zilian's words, Li Nan couldn't help laughing.

"Well, I feel like you're a bit of a bull. In my opinion, there is no right or wrong in your question, it is just a matter of values. ”

"Your question, if I had to choose, I would probably choose to destroy that enemy, although he has his own troubles, but he has done a lot of bad things and killed many people, this is an indisputable fact, so it is beyond reproach and a matter of course to eliminate him."

"Well, I know, I think so too, but the problem is that after the enemy is destroyed, there will be people who will be sad ......," Duan Zi said in a tangled manner.

Now, although he sympathized with Zheng Yulong's experience, thinking of the bad things Zheng Yulong had done before, he was already determined to defeat Zheng Yulong.

However, thinking that Ling Lanjing would be sad because of Zheng Yulong's death, he couldn't help but want to take into account Ling Lanjing's feelings, so that his determination would be shaken.

And this is the problem he has been struggling with.

Li Nan continued to say earnestly: "Even if this is the case, there is no way to do it, after all, it is based on the overall situation, and it is a last resort, and in a desperate situation, I have to do this." ”

"You know, sometimes, you have to face the situation of having to sacrifice a small number of people in order to save the majority, even if that choice is painful and cruel."

"At the expense of a small number of people in order to save the majority...... ......" Duan Zi muttered to himself, thoughtful.

patted Duan Zilian's shoulder, Li Nan said seriously: "Yes, the so-called fish and bear paws can't have both." For the sake of most people, we can only sacrifice that small number of people. It's impossible to keep everyone from harm, like anime, because in reality there is usually no such thing as the best of both worlds, and that's too idealistic. ”

"So, when you are faced with this choice, unless there is really a third way out, you can only be ruthless, sacrifice that small number of people, and bear this sin to wake yourself up."

"What's more, there is no such idealized hero in reality, and heroes under normal circumstances, no matter how glamorous they are on the surface, will always be more or less burdened with sins."

"If you want to hurt nothing, then I can only say that this idea is too naïve, you don't want to hurt anything, you don't make a decision at all, and the result is often to hurt everyone."

"That's right...... Is there only a choice to make? Even if this choice is cruel and painful......" Listening to Li Nan's words, Duan Zilian fell into deep thought.

Exhaling, Li Nan concluded: "Okay, that's all I have to say. There is no right or wrong question for you, the most important thing is to make a good choice according to your own position. ”

"If there is really no way but to sacrifice a small number of people, then you must carry this sin on your back, always warn yourself, and try not to let something like this happen again."
