Dark Night begins to look for what Black Hawk said about the nerd, but there are too few helpless prompts, and there seem to be a lot of such people in the car.

"That hint is meaningless if you can't specify the object......" said the night, "Was I such a stingy person in my previous life?"

"Little Black ......"

The night was suddenly startled, looked around, and found that no one was calling him, and couldn't help but sigh: "It's all Xiaobai, there are auditory hallucinations at this time...... He then chanted: "Darkness, black eagle, night...... Darkness, Black Eagle, Dark Night......" After he was silent for a while, his muscles protruded, and he said in his heart: "Although I think this method is very brainless, but let's try it......"

"Blackie, are you there?" called out as he walked through the night, and he called ten times in a row.

"That's enough, you bastard, don't call me by my nickname anymore! don't you just want me to write on your box?" Suddenly, an old man in the carriage suddenly stood up and yelled at the night.

The night turned to look at the old man, and saw that he was wearing reading glasses and looked like a scholar. The night felt the sensation of electricity passing through his body again, then wiped his cold sweat and said secretly: "Although my age is unexpected, I am indeed a nerd." It worked......"

The old man cleared his throat and said, "That...... The old man's name is Blackwater, please take care of it!"

"Got it," said Night, "what do you want me to do to write on this box?"

"The young man is really straight to the point, then the old man will not sell lawsuits, the answer is this!" said Heishui, and took out an item. Contrary to the darkness of the night, it turned out to be a handheld game console.

"Dare you ask if you've been struggling with this thing since just now?" said the night.

Blackwater laughed, "yes, this thing is my old buddy now." ”

"Yes......" said Dark Night Wiping Sweat.

"Don't look at the old man who is a bad old man now, when he was young, he was a know-it-all university scholar!" said Heishui, "But after all, when you are old, your brain has long since degenerated and become old." But fortunately, there are old guys here, and there are hundreds of intellectual games in it, so the old man has not suffered from Alzheimer's disease until now. ”

"I see......"

"Here, this is Lao Yu's favorite game, you come and play it," Heishui said as he handed the "old man" to the night, "This is a number guessing game, that is, you guess a four-digit number without repeating numbers, and each guess will give back a result of 'A and B', where the number before A represents the number of numbers in the correct position, and the number before B represents the number of numbers that are correct but not in the right position, and you have to continue to guess the number according to this feedback result until the feedback result shows '4A0B', that is, it is completely correct." There's no need to be stressful because there's no limit to the number of times. ”

"Well, isn't this just a puzzle game for kids? Hei Ye said, and then entered the game, and after a while, he showed Heishui the "old guy" that showed "4A0B", "The answer is 1209, and it took 7 chances to guess." ”

"Oh, the young man is pretty good!" said Blackwater.

The dark night looked around and said, "Strange, why does it feel like all the passengers have changed?"

"Of course, because it's been six days. "Blackwaterway.

"What!" exclaimed the night, "what are you kidding, you old man!"

"Don't worry, you don't have to worry about your companions, they will have at least another week to join you," said Blackwater, "In short, time passes quickly when people are highly focused, and after playing this game on my old fellow, every time you guess wrong, 24 hours will pass in an instant to the next day, and time will not be affected if you answer correctly." ”

"Why didn't you say something so important earlier?" asked Darknight.

"If you knew in advance, would you stop thinking about it after time flies because you guessed wrong again and again?" Heishui asked rhetorically, "In life, don't believe in this world too much, but don't doubt this world too much, you have to learn to separate the false from the true, this is very important but it is also very difficult, so don't stop thinking at any time." ”

The night can't say anything about it.

Blackwater continued, "Alright, let's take the box out. He then took the box from Night's hand, and gave it back to Nightnight after making a few strokes with his finger on the other side. This time it's a "true" word. He said again: "Okay, it's time for a personal reminder, are there elves in this world?"

"What?" said the night, he didn't expect the prompt to be a question this time.

"If you want to know the answer, find out for yourself, knowing too much and giving up thinking is against the original intention of old age. I'm sorry, but I'm going to go around another car. Blackwater said, returning the box to Night, then stood up and walked away.

"Here we go again......" The moment the night touched the box, I felt a severe headache again, and a large number of memories flooded into my brain. He wanted to ask what was going on, but he saw that the water was nowhere to be seen, so he simply walked to the next carriage in the opposite direction.

The night was repeated, and while calling for "little black", he moved forward, and unconsciously came to the No. 5 car, only to see what the passengers were watching in this car. When he stepped forward in the dark, he found a young man watching, and heard him say:

"Did you know that there really are elves in this world......
