The first group departed first, and two hours later, the second group departed. An hour later, the third group set off again. The intention of this arrangement is obvious, and I am afraid that the situation inside is unclear and the whole army will be wiped out.

Chen Jian wanted to be in a group with his father, but was reprimanded by Professor Chen, and the professor took the first group to go first. The rest of the people just waited in place, and the time passed very quickly, and the second group was about to set off again. Watching everyone walk into the deep black hole, I inexplicably felt a wave of nervousness and anxiety.

As the minutes passed, I couldn't sit still, even though I knew that there was no threat here, I was still nervous, and I went back and forth in circles.

Li Damin sat cross-legged on the ground, his hands on his knees, and he was closing his eyes to recuperate.

At this time, I admired him a little, Li Damin has strong self-control and self-discipline. He must have been anxious in his heart, he was facing more danger than me, but his self-control at this time was admirable.

What surprised me even more was the man named Wang Yuantong. Among these ten people, he is not good-looking, we didn't pay attention to him at first, but now that we are in a group, we think this person is a little interesting.

He was the only bald man in the group, leaning against a tree and looking at a pamphlet in his hand with relish.

Chen Jian sat on the ground, boredly hitting the leaves with stones, mixing time. In this way, it seems that I am the least calm person.

The last group of these three people did not have a leader to follow, so the captain was temporarily appointed, and Li Damin was the big one in the middle of the pack and became the temporary captain.

After waiting for a while, Wang Yuantong put down the book in his hand and said, "Captain, it's time, are you going?" ”

Li Damin opened his eyes from a state of false sleep, stretched his waist, and instructed everyone to check the equipment and pack their backpacks. Li Damin walked in front of him in a mountaineering windbreaker, which was quite a bit windy and cold, and the others followed behind.

When I arrived in front of the deep cave, a foul wind blew out, almost blowing away my disembodied consciousness, and obediently boomed, this place is too ghostly.

I have no words to describe this scene in front of me, it is too small to say "evil", it is not accurate to say that it is weird, the darkness and fear in front of me are too vast, like a sea of nightmares that can drown a person.

Li Damin was the first to walk into the cave, his body was swallowed by the darkness, and the dazzling flashlight was like a firefly in the darkness.

Chen Jian walked in the second, and Wang Yuantong hummed a little song and the third went in. I don't have a body, I can't hold a flashlight, and in the bardo realm, I am not afraid of heaven and earth, but I am afraid of the same, that is, I get lost in the dark.

There is nothing I can do about this difficulty. When I encounter danger, I can move my mind to go out, but when I come back in, I still can't find my way in the dark, and it's still useless. And I can't touch any of the lighting tools.

In the current situation, I can only follow the team, follow their flashlight, and dare not be distracted. Once they are lost, they will be able to find them.

Fortunately, the hole is not completely swallowed, and the light flickers in the dark, and it is still relatively clear under normal circumstances.

Li Damin walked very slowly, and every time he walked around a corner, he would make a mark on the wall. His marking is extremely professional, it is really the level of an old exploration team, it seems that this year has not been in vain, and he has learned a lot.

When he was making marks, the team members gathered around to watch, and there were other marks made by the team in front of him on the wall, it seemed that the team of ten people was indeed selected by thousands of people, and each operation was very in line with the process and was particularly standardized.

After walking a short distance, I found the pattern of this hole, that is, there are many bends. There is a bend almost every few dozen steps, and in my experience, it's not too bad, and you can definitely get out, because there are no forks in the hole, and the bends are all one-way.

After walking for more than an hour, Li Damin beckoned everyone to sit down and rest, drink some water and eat some compressed biscuits to replenish their strength.

"How?" I sat next to him and said.

Li Damin shook his head and whispered, "I don't have a score either, but one thing is certain, the real test has not been opened." ”

As soon as he finished speaking, Wang Yuantong suddenly said in the dark: "Captain, who are you talking to?" ”

"No, I'm talking to myself." Li Damin glanced at me, shook his head slightly, and signaled that he couldn't say anything more.

The cave was very quiet, except for a few people snorting and panting. Anything you say here can be heard.

Chen Jiandao: "Brother Damin doesn't know what's going on these days, he always likes to talk to himself. ”

Li Damin diverted the topic: "Okay, it's time to go, I don't know how the two teams in front of me were, what did they find." ”

He stood up and continued to walk forward, with Chen Jian and Wang Yuantong following behind.

This time I learned to be obedient, I won't easily talk to Li Damin if there is nothing special, Li Damin just knows that I am here, and a tacit understanding has been formed between us.

Walking Li Damin stopped and looked down at his watch: "This speed is not good, I have only walked three kilometers." ”

"It's not that we can't," Wang Yuantong said, "this place is so dark that the consumption is three or four times that of usual." ”

"That makes sense, but we're an elite team, otherwise why would we be transferred as an advance force." Li Damin said: "From now on, I will step up, Chen Jian, do you have a relationship?" ”

"Brother Damin, I'm fine." Chen Jian said excitedly.

Wang Yuantong scolded: "Chen Jian, now he is working and on a mission, even if Li Damin is your brother, you can't call your brother, you have to call the captain." ”

"Yes, Captain!" Chen Jian said loudly in the dark.

Li Damin laughed, shining a flashlight in front of him, although the height of the top of the cave at this moment is not as grand as the cross-section of the hole, but visually it looks like a huge garage, and it is no problem to park five or six large trucks side by side.

The flashlight shone on an area, and Li Damin let out a strange "um": "Have you seen it?" ”

I saw something strange on the ground, not very big, like a carry-on object.

A few of us ran over, and when we came closer, Li Damin squatted on the ground and carefully shone it with a flashlight, so that he could see what it was.

It turned out to be a harmonica, very old, covered in rust, stuck in the middle of two pieces of rubble.

Li Damin and Wang Yuantong looked at it, and Wang Yuantong said: "Captain, it may be that the two groups in front of me were dropped by someone who didn't know." Li Damin thought about it, reached over and picked up the harmonica, and blew it with his mouth, stirring up a lot of smoke and dust.

"It looks like it has been abandoned for a long time," Li Damin said, "and it doesn't look like the first two groups dropped it." ”

Chen Jian suddenly said, "Can I take a look?" ”

Li Damin handed him the harmonica casually. Chen Jian took it and looked at it again and again, his expression was very strange. Wang Yuantong asked curiously, do you know?

Chen Jian's lips trembled, and he said softly: "This, this is my harmonica." ”

As soon as the words fell, I suddenly heard the sound of the "Gadagada" clock from the depths of the cave.

As if remembering something, Li Damin raised his head sharply and shone his flashlight on it. All of us saw that above the cave wall opposite, there was a huge clock hanging with strange hands, walking backwards counterclockwise.

I exclaimed, "It's time to get started!" ”

Li Damin was a little stunned, and muttered, "The harmonica turned out to be an organ." ”

Chen Jian was particularly scared: "Captain, Brother Yuantong, how can there be a clock here?" ”

Li Damin comforted: "Don't panic, this hole is weird and inexplicable, and it makes sense for anything to appear." ”

The reason for this strange situation at the scene may only be known to the two of us.

I said next to me, "Damin, it's not appropriate for you to talk to me now, I said you just nodded." Now we only have twenty-four hours. ”

Li Damin nodded.

"The only clue to solving the problem here is the harmonica." I continued.

Li Damin agreed, and he made a gesture to signal me not to speak for the time being. He asked Chen Jian, "Is this harmonica really yours?" ”

Chen Jian didn't know whether he was scared or nervous, his face turned pale, his lips trembled, and he couldn't speak: "The harmonica is really mine!" Word by word, he said, "It was a gift from my father on my fifteenth birthday." ”

Wang Yuantong suddenly said: "Chen Jian, aren't you only fourteen years old, and your fifteenth birthday hasn't passed yet, how can your father give you a gift?" ”

Chen Jian froze suddenly: "Yes, I'm only fourteen years old, why do you say fifteen?" That sentence just now seems to pop out on its own without going through the brain. ”

"It doesn't matter how old you are," Li Damin said, "Are you sure this was given to you by your father?" ”

Chen Jian's face was frightened, and the harmonica fell to the ground. Wang Yuantong hurriedly picked it up and blew it, "I said what's wrong with you, what the hell?" ”

"My dad didn't give me this harmonica now," Chen Jian said in horror, "why do I think it looks so familiar?" It seems to have been accompanied for a long time. ”

Without waiting for Li Damin to speak, Wang Yuantong laughed: "Maybe this is something from the future." You received this harmonica at the age of fifteen, and then it stayed with you for many years, and now it flies back in time to when you are now fourteen. ”

Li Damin's gaze fell on him.

I said softly: "Damin, something is wrong, this Wang Yuantong is wrong." ”

Li Damin nodded slightly, his eyes locked on Wang Yuantong's body.

In the words that Wang Yuantong just said, many words in them should not belong to this era, such as "future" and "crossing", these words are too modern.
