The branch is very dark, and the darkness is frightening.

The branch road is also very quiet, so quiet that people dare not gasp.

But fortunately, although the branch road is called a branch road, it is still very spacious. Even if Xiao Chu and their group are three people, it is no big problem to walk side by side.

Before entering, Bingxiu noticed one thing - there was a special pattern on the entrance of each branch road, although it was all worn out very badly, it could still be distinguished.

"Chubby." Bingxiu called Xiao Fat.

"Huh? What's wrong?"

"When the time comes, when we go out, you use your camera to take pictures of all six entrances, and you have to take pictures clearly and meticulously."

"That's fine, I'm confident in my camera skills!" Xiaopang's voice was a little higher, and the whole branch echoed endlessly.

"Oh my God! Chubby, speak quietly! I'm sick of this echo!"

"Ahh Sorry!" After Xiaopang finished speaking, there was another echo......

"Forget it, you just try to keep quiet...... Keep walking! ”

Moving on –

At the same time, the light is getting weaker and weaker, and the whole branch is getting darker and darker.

Bingxiu and Chubby stopped, each rummaging through their backpacks to find the flashlight they had prepared earlier.

At the same time, almost every group in the six branches began rummaging for flashlights.

"Really! After all, it was also a big investigation, and he didn't even give some lighting facilities, so why didn't he kill him? Chubby began to complain.

"You...... Don't talk...... What can we do, people have already withdrawn, haven't you heard Mi say? People are friendly and helpful!"

And on the other branch road, that is, Xiaochu's group, they didn't go fast, they were all the same dark and the same difficult.

Another person in the same group as Xiaochu (not Li), his name is Xia Qiu (hereinafter referred to as Xia), although the name is quite feminine, but he is a young man, and I have said before that there is a woman in Xiaochu in the team.

Xia is taller, thinner, with glasses, three-seven-point hair, and has a lot of personality. At the same time, the age is still older than the junior high.

"Our expedition is an investigation, how can it be like a tomb robbery......" Xia muttered.

"It's really special, but it's also a very precious experience! Ha ha. Xiao Chu was comforted.

Moving on –

At this moment, Xiao Chu's receiver suddenly rang.

Xiao Chu listened to what was said inside: "Xiao Chu, have you noticed the wall of your branch road?" "It's a member from another branch who called.

"On the wall? What's wrong?"

Xiao Chu was very curious, she really didn't pay attention.

"You'd better take a closer look, I don't know if there's anything in your branch, but here I am, there's a lot of strange geometry carved on the wall."

"Okay, I'll take a look."

Xiao Chu picked up the flashlight and shone it at the wall-

Really!

There are really a lot of strange geometric shapes on the walls, like a huge design drawing.

"First, I'll connect everyone at once!"

Xiao Chu quickly connected everyone, and as expected, there was such a geometry on every branch road.

"Didn't the professors notice that they didn't notice that on that expedition a few years ago?" Bingxiu said.

"This is not clear, so let's make a record first, and I will contact the professor."

So everyone began to record with flashlights.

"Chubby, can you take a picture of this?" Bingxiu asked.

"Hmm...... You help me light, no problem!"

"Good!"

With Chubby's photo, Bingxiu and the two of them are much more convenient.

On Xiao Chu's side, Xiao Chu was contacting Professor Shen......

The professor had been paying attention over there, so it was quickly passed.

"It's Xiao Chu! What's wrong?" Professor Shen asked.

"Professor, we are investigating the branch of the underground research institute, and we found that there are a lot of geometric shapes on the walls of the branch road, I don't know if you found this thing before."

"Ahh Of course, it was discovered, and research was carried out at the time, but there was no clue as to the usefulness of the geometric figure, so later some people said that it was used for decoration, and there was no better way to say it, so everyone acquiesced. ”

"Ah, that's right!"

"But it may not be that simple, although there have been no research results, but maybe you can find something." The professor added.

"Well, Professor, we're going to record and study every discovery."

"Okay, just tell me if there's a situation, and I'll keep an eye on it."

"Understood, Professor."

After contacting the professor, Xiao Chu once again told everyone to record carefully.

Keep moving......

"Sister Li, it's uncomfortable here, if you feel uncomfortable, you can wait for us outside like Mi, I still have Xia here, it's okay!" Xiao Chu said to Li.

"No, it's because of the discomfort here that I want to accompany you, this is not only the task given to me by the professor, but also the love!" Sister Li said it seemed to be very relaxed.

Xiao Chu also felt very moved, but now is not a place to sensationalize, Li is good, Xiao Chu will remember.

"Okay, Sister Li, I'm really grateful to you"

"You don't have to thank me at every turn in the future, it's what I should do!" Lee was smiling as he spoke, but it was too dark for anyone to see.

Xiao Chu didn't say anything more, took Li's hand in the dark, and walked together.

The gaze shifted to Bingxiu and Chubby's side again-

"Chubby, get the camera."

"You still need to say that I can't throw it away if I throw it myself." Chubby now knows how to speak in his voice, which makes Bingxiu feel a lot better.

"Huh? Brother Xiu ......, "Chubby suddenly wanted to say something.

"What's wrong?"

"It's ...... It's not going to be so dark forever, is it? This front...... Why is there no light at all?"

Chubby's words caught Bingxiu's attention!

"There's really no light!" Bingxiu muttered.

Suddenly, Bingxiu turned his body around, and because he turned too hard, he actually bumped into Xiaopang face to face......

"I'll go! Brother Xiu, what are you doing? Startle me......" Chubby activated his loud voice again.

And this time, Bingxiu did not pursue ......

Bing Xiu didn't say a word, if it wasn't so dark here, you could clearly see Bing Xiu's pale face!

Then, Bingxiu spoke—

"Little... Chubby!"

"What's wrong, Brother Xiu? Why are you still stumbling? Chubby also made some fun of Bingxiu.

"It's not! Chubby, turn around and take a look!"

Chubby turned around curiously......

Then he said, "Isn't it still pitch black?" Brother Xiu, what the hell is wrong with you? ”

"Chubby, let me ask you, did we keep walking in a straight line when we came in?"

"Hmm...... That's right!"

"Let me ask you again, have we been gone for a long time?"

"It's not a long time! It's so dark in here, we're walking very slowly! However, it can't be helped. ”

"No, let me ask you again, isn't that rotunda outside the lab very bright?"

"yes, the holes in the roof of that hall are exposed......"

"Brother Xiu......" Chubby suddenly realized that something was wrong.

"You noticed it too? It stands to reason that there should be light in the distance, and even if there is none, there should be a bright spot. It's black, it's just ......" Before Bingxiu finished speaking, Xiaopang picked up.

“…… Brother Xiu, we're here to investigate, we're engaged in scientific research! How...... What the hell is this? Chubby was visibly scared.

"Go to the side! Knowing that he is engaged in scientific research, how can he still believe in ghosts? Although this is indeed abnormal, it definitely has nothing to do with the hell or anything. Bingxiu seemed much calmer now.

"Okay, Brother Xiu, you have to protect me, and my receiver is not easy to use."

"Don't worry...... Feel relieved. Bingxiu tried to give Chubby some security.

"That'...... Would you like to tell the other groups about this?" Chubby asked.

"Don't do it yet, wait until you go back, it's not suitable to say it now, in case the big guy has stage fright, the effect of the investigation will be greatly reduced!"

"I really envy the professor's previous investigation, the lighting facilities are so good, which is like now, pick ...... to death" Chubby began to complain again.

"Alright, let's go! Since a professor has been a pioneer, it means that this place is safe, don't we still have a flashlight! I guess it won't be too long! ”

"Hmm......" Chubby had to promise.

Everyone walked forward, and there was nothing unusual in the side roads except for the strange geometry on the walls.

About ten minutes passed......

"Brother Xiu, why hasn't it come to an end yet?" Chubby asked.

"I don't ...... either" Bing Xiu was just halfway through his words, when his eyes suddenly opened up, and another spacious and bright hall appeared in front of him.

Bingxiu was surprised and didn't dare to speak......

Obviously, it was still pitch black just now, and almost suddenly, a ...... appeared in front of me

Bingxiu looked back, the branch road was normal, and it was not so dark because of the light in the hall, but ...... It was pitch black just now......

At the same time, Chubby looked at the hall blankly, his eyes straightened......

Bingxiu eased up a little-

Several figures were found in front of the hall.

When I got closer, it was Xiao Chu and them.

"Xiao Chu ......," Bing Xiu called very softly.

"Brother Xiu! You're coming out too!"

"Xiao Chu, you found ......"

"I already feel it, and I can't tell why!" Xiao Chu hurriedly answered.

"How long have you been in this hall?"

"Hmm...... I'll take a look. Immediately, Xiao Chu went to look at her watch.

"Repair... Brother Xiu!"

"Huh? What's wrong?" Bingxiu asked suspiciously.

"What time did we come in?"

"Ah...... I think it was around 12:10! Bingxiu replied.

"Look at your watch." Xiao Chu seemed very anxious.

"How?"

"Look!"

Bingxiu was confused and glanced down at his watch......

At that moment, a lot of cold sweat appeared on Bingxiu's forehead.

Because......

Time – 12:12

Xiao Chu and Bingxiu looked at each other, and neither of them knew what to say.

"But, just now, I was on the phone with the professor!" Xiao Chu said.

"No, no, I'm talking to the professor right away and asking him what he just ......."

"Hmm......" Xiao Chu hurriedly talked to the professor, and now, the members of the various branches have arrived one after another, and they have all found these unusual, and no one dares to say anything.

I got through with the professor......

"Xiao Chu? How's it going?" The professor asked.

"Professor, did I just talk to you?" Xiao Chu seemed very anxious.

The professor seemed confused......

"I was taking a nap just now! I've always had this habit, Xiao Chu, what's wrong?"

"Professor, you really didn't talk to me just now?......" Xiao Chu asked again!

"No, is Xiao Chu too tired and confused? Haha!" The professor still seemed relaxed.

Xiao Chu was silent for a while, and everyone stared at the boss.

"Professor, did you try no light source last time you visited?" Xiao Chu spoke again.

"No, there's always a light source, don't you have one?"

"Nope."

"I'll tell them, don't worry."

"Okay, Professor, let's do this first"

Xiao Chu hung up quickly......

"Hmm?...... Xiao Chu? Why don't you ask more about it?" Bingxiu asked.

Everyone is curious.

"No need to ask, let's not let the professor worry about it first. The professor also said it, but it didn't pass the words."

"That ......"

"We, now, wear it back!"

"Now?" Li also asked.

"Yes, now"

Everyone is optimistic about the watch——

12：18

The group didn't even have time to take a few more glances at the hall, and hurriedly turned back......

This time, everyone's steps were firm and fast, turning on the flashlight, and moving forward.

No one spoke, and everyone was in a hurry.

Feel......

It took less than 20 minutes before I wore it back.

Mi looked surprised and said, "What's wrong?" Why did you just go in and come out again. ”

No one spoke...... But we all know that even if we can't believe it, that happens.

Look down at your watch –

12:18 p.m.!

Chubby didn't forget to shoot the entrance.

Lee Jae explained to Mi over and over again.

And a word popped up in Xiao Chu and Bingxiu's thoughts almost at the same time-

Black hole!

Perhaps, it may be the black hole of time...... But neither of them said anything.

It was still early, and everyone had spent those few minutes on the side road inexplicably.

"Chubby, have you filmed everything?" Bingxiu asked.

"yes, alright."

"Xiao Chu, what should I do next?" Bingxiu looked at Xiao Chu very seriously.

"Let's observe here first, and I'll go discuss something with Mi."

"Sister Li, you come with me and help translate." Li and Xiao Chu planned to go to Mi together.

"Xiao Chu, I explained to Mi for a long time just now, but Mi doesn't seem to understand." Lee said.

"I'm sure I won't understand, and I won't believe it either."

"Hmm...... So what are you going to say?" asked Lee again.

"I don't explain, I just need the lighting and my knowledge of astronomy."

Li nodded, and followed Xiao Chu to the side of the meter.

"Mr. Mi, I have a small request." Xiao Chu said.

Li grasped the translation ......

"What? If it's the same request as that person (Bingxiu) last time, it's not okay. Mi said.

On the side, Bingxiu glanced at Mi and gently "cut~". But the superfluous was not done.

"No, it's not. I just want to have the lights on it. Xiao Chu explained.

"Lights? That is, these small branches are relatively dark, and the rest does not matter, and don't you all have your own lighting equipment? ”

"Mr. Mi, for the sake of the smooth investigation, I still ask for your permission, and I have already contacted the professor, and the professor also thinks that there should be lighting facilities." Xiao Chu looked at Mi.

"At least the day after tomorrow!" Mi said again.

"The day after tomorrow, just right, I hope Mr. Mi can come to us tomorrow, we still need your professional guidance for some questions about this inspection." Xiao Chu was very polite when he said this.

"Hmm...... That's fine, I'm willing to offer my knowledge. ”

"Well, thank you, Mr. Mi."

"You're welcome!"

Xiao Chu walked back after speaking, and was pulled over by Bingxiu.

"Wouldn't it be more troublesome for you to involve him in our discussion and research?" Bingxiu was confused.

"Brother Xiu, this is not necessarily!" Xiao Chu replied jokingly.

"How?"

"Mi's knowledge about astronomy is still very rich, and tomorrow I will not only invite Mi to participate, but I will also connect the professor when I research and discuss."

"Professor?"

"Hmm."

"Are you going to tell the professor all this?"

"Brother Xiu, this is a must, I think it's time to talk to the professor. And, I told the professor in advance tonight, "

Bingxiu's face was full of doubts, and without Bingxiu speaking, Xiao Chu continued: "Only by letting the professor understand all this can he be more able to establish a connection with that branch flower." ”

"Hmm......" Bingxiu thought for a moment and didn't say anything more.

The sun's rays gently shone down from above, Bingxiu looked up, Xiao Chu was talking to Li over there, but he was not interested, he was trying his best to think, flowers-laboratory-these strange, unreasonable things, are there some connections? He thinks there should be, no! There must be!

Bingxiu had a bold guess......
