"Brother Liu, what's wrong?" Hu Qianxue asked, after all, she looked at Liu Yixuan's movements, which was really a bit abnormal.

Liu Yixuan told them all the information he had just learned.

"And this kind of rule, then you're in luck." Xiao Qinghua was a little surprised.

"So are you getting better now?" Hu Qianxue asked with concern.

"Well, at least you won't be able to run like you just did, okay, let's not talk about it, it's important to get down to business."

After Liu Yixuan finished speaking, he began to search, and finally found the black box under Zhong Xingxian's body.

This box looks no different from a normal box, except that between the open gaps, there are numbers that can be toggled, and it is exactly four digits.

According to the current information, Zhang Chengzhi's birthday is September 16, so if you judge it with normal thinking, the password should be ......

0916

Whether he's right or not, give it a try.

But when Liu Yixuan toggled it and opened it, the sound of a copy prompt suddenly came from his head......

[The password is wrong, there are two chances left to enter, if the opportunity runs out, the box can never be opened]

Sure enough, the password won't be that simple.

But no matter how you think about it, you don't have any clue, because the information is clearly written, Zhang Chengzhi's birthday is September 16.

"No, I can't unlock this password." There was no way, Liu Yixuan had to ask for help from the other two: "There are only two input opportunities left, if you lose both times, then this box will never be opened."

"Isn't the password 0916?" Hu Qianxue asked, obviously her thoughts were the same as Liu Yixuan's.

"I just tried, no."

"That's kind of interesting." Hu Qianxue lowered her head and seemed to be in trouble.

"I don't have any ideas about this." Xiao Qinghua waved his hand helplessly.

Liu Yixuan also shook his head silently.

Suddenly, the whole scene fell silent, as if in a terrible morgue, and the faces of the three of them were full of contemplation in the faint light of kerosene lamps.

After all, for this password, the tendon in the head really can't turn around......

"I have an idea." In the end, it was Hu Qianxue who took the lead in speaking: "He only said that his birthday was the password, but he didn't say whether it was the solar calendar or the lunar calendar."

"You mean, this password is his lunar birthday?"

"That's right."

"Then it's not easy to get it, no matter which information says the year of this incident, it is impossible to speculate on his lunar birthday." Xiao Qinghua directly picked out the difficulties.

Hu Qianxue looked at Liu Yixuan expectantly: "It depends on Brother Liu."

Ah......h Look at me?

Liu Yixuan was a little confused, but he still thought about it carefully, although it was a long time, he could still remember the year.

"It was '02."

"But it's useless to know, we won't convert the lunar calendar." Xiao Qinghua said.

Hu Qianxue ignored him: "Brother Liu, if I'm not mistaken, the smartphone you picked up still has a calendar function, right?"

"I'm rubbing, I forgot about that!"

Liu Yixuan slapped his head and reacted.

Then I took out my smartphone, and it showed that there was 4% left on the battery level, and it looked like it was about to turn off.

Liu Yixuan didn't dare to delay, and quickly flipped through the calendar......

In the end, when there was still 1% of the battery left, Liu Yixuan found the answer he wanted.

On September 16 of 02, it is the tenth day of August when converted into the lunar calendar!

So, Liu Yixuan tossed the number watch on the black box, making the number 0810......

[The password is wrong, there is only one chance left to enter]

Ahh

"Still wrong." Liu Yixuan said this sad result with great regret.

"What's that?" Hu Qianxue was stunned: "If this is all wrong, what else will the password be?"

"One last chance, if the password is still wrong, I'm afraid we'll all be doomed." Liu Yixuan said word by word, and his face was also very heavy.

Actually, this is not to scare them, completing the hidden mission is the only way for everyone to survive, and it is simply impossible to hold on for more than two hours.

After all, these ghosts are intelligent, and although they are bound by taboos, players can never guess what they think......

It can be said that if these two ghosts want to kill someone, no one on the scene can stop him!

Liu Yixuan took out the note, and then the three of them leaned together to look at it, thinking about what the answer to the password would be.

……

"Do you guys have any ideas?" After a long time, Xiao Qinghua asked.

"No, I really can't figure this out, except for this year, month and day, I really can't think of any other numbers related to this." Hu Qianxue said with some grievances.

Xiao Qinghua: "I have an idea."

"Tell me about it."

"Could this password refer to Zhang Chengzhi's birthday year? It's exactly four numbers too. ”

"Impossible." Hu Qianxue immediately refuted Xiao Qinghua's proposal: "On the note, it is clearly written what Zhang Chengzhi said, 'It is the period of this year's birthday, and the day of the previous birthday is not'." I don't know what this means, but at least I can rule out the possibility that the year of birth is a password. ”

"Oh, okay." Xiao Qinghua shook his head in frustration: "I'm really not good at these mental work, so I'll leave it to you."

Liu Yixuan seemed to grasp the point, and immediately said: "Wait, there is a problem in what Zhang Chengzhi said!"

"What's the problem?"

Liu Yixuan smiled and said, "Hehe, just because of this sentence, I also have an idea, but I don't know if it's right or not."

"Don't hang people's appetites, can't you just say it?"

"I don't, who made you like this by the lake."

"Hmph, stingy, who wants to know the same." Hu Qianxue stuck out her tongue at Liu Yixuan.

Liu Yixuan shook his head and smiled helplessly, then dialed the numbers on the box and slowly entered the password.

9167

Click.

This time, the box opened easily, and the sound of a copy appeared in my head.

Liu Yixuan looked inside and found that there was just a car key lying quietly inside, and it was still a brand new one, and there was nothing else.

"You really know the password, what is the password?" Hu Qianxue asked in surprise, as if she thought Liu Yixuan was joking just now.

"My brother is amazing." Xiao Qinghua also shouted 666 next to him: "How do you know the password, tell us, it's impossible to guess, right?"

"Of course not." Liu Yixuan touched Hu Qianxue's little head, and the smile on his face suddenly disappeared: "Time is running out now, let's hurry to the parking lot first, and I'll tell you the idea again on the way."

"Okay, let's go."

"What is the password, you can tell me the answer first." Before she could take a few steps, Hu Qianxue pestered and asked.

“9167。” After Liu Yixuan said the answer, he asked rhetorically: "Do you know why?"
