Xiaoyu and Shidan walked in the cave, this is their third exploration of the Black Mountain Cave, although it is a long way for the two children, but it is also a light car, a box of matches, is their only tool; Along the way, every time they turn a corner, they draw a match, look at the mark on the wall, the road ahead will be familiar with the heart, it will never be wrong, so as to save time, but also to waste as little match as possible, they are very clear about the importance of matches, once the match is used up, it means that the direction is lost, as long as there is a match in the hand, there are marks on the wall, you will be able to find the Black Mountain Cave!

When Grandpa and Dad were not in trouble, they often told them stories, telling them stories about what they experienced during the war years. Especially Nianzi, he likes to tell stories about intelligence officers, and Nianzi also loved to listen to stories when he was a child. He liked the job of an intelligence officer, at that time he was still young, working as a buddy in a small shop, usually bringing tea to sweeping the floor to greet customers. When I was resting, I pestered the old intelligence officer to tell stories, those thrilling stories, witty and brave intelligence officers, thrilling! He spoke to the two children with an expression on his face, as if he were there. The colorful performance planted an indelible seed in the hearts of the two children! When they played with Niu Er and Xiao Zhuge together, they often acted in a scene where the intelligence officer wittily sent intelligence.

They didn't know how long they had been walking, but when they struck a match, they looked at the marks on the wall, and then looked at the environment in the cave, and the images in their memories were reflected in their minds, and the two children smiled heartily! One more roundabout, and you'll be in front of you, the Black Mountain Cave!

Just as they were about to go around and continue walking, they suddenly felt a gust of wind flash! They quickly crouched down, held their breath, and listened intently. Xiao Yu and Shi Dan once heard Xiao Zhuge say that if you hear a strange sound in the cave, you should put your ears on the wall and listen carefully, if you hear footsteps, you can hear a few people, but don't move yourself first, so as not to be discovered by the other party, which is very important! As long as you don't move, the other party will not dare to act rashly! So Xiaoyu and Shidan put their ears on the wall and listened carefully, and after listening for a long time, Xiaoyu asked Shidan, did you hear anything? The stone egg blinked his eyes and didn't speak for a long time. Xiaoyu said eagerly, ask you, are you talking? Shi Dan said, he didn't hear footsteps, as if he heard the rustle of leaves falling to the ground, but he wasn't sure! Xiaoyu said, yes, I feel the same way, what's going on? How can there be the sound of leaves in the tunnel! An inexplicable fear strikes me!

Two children, you look at me, I look at you, the two of them squatted there motionless, no one was at a loss!

What to do? In this tunnel where you can't see your fingers, you don't dare to walk, you don't dare to draw matches, the movement just now makes them feel frightened, and they have a task on their bodies, and they need to move on, the Black Mountain Cave is in front of them, what can I do?

Last night, grandpa's anxious, dignified, and helpless look once again appeared in front of him, and even the dream words in the dream were tossing grandpa, you can imagine how important this matter is, we don't move here, how to complete the task! We once swore to our grandfather that when we grow up, we must be a big hero like our grandfather! Grandpa is in trouble now, no one helps Grandpa, only we can help Grandpa, and now I have encountered a little difficulty, is this afraid?

Xiaoyu said, no, we can't wait like this any longer, grandpa told us a story, time is life, time is victory, on the battlefield, we must fight for every minute and every second, every second of time, the certainty of victory will be one more point! Shi Dan said, yes, let's go! Xiaoyu said, no, let's lie down, the goal is small, the movement is small, and it is faster than walking, and it can also buy time, the Black Mountain Cave is not far away, it will be there in a while, grit your teeth, hold on for a while!

Xiao Zhuge and Niu Er were looking for the secret cave that Lao Balu hadn't found last time. Xiao Zhuge said, we can't always be idle like this, my injuries are almost good, and it's time to do something. If the commissioner and Li Changji were still here, they would definitely be in this cave, and you think, what a terrible thing it is for us to live in the same room with them every day! One day our heads move, and we don't know how Lu Dao died, this is a terrible thing! Niu Er said, didn't the eighth master say that it was very likely that they were gone? Xiao Zhuge said, who saw it? Are you sure they're 100% gone? Didn't they still appear at the public trial meeting a few days ago? You have seen this with your own eyes, and when you and the Eighth Master chased after them, they fled to the mountains, can you be sure that they will not return to the secret cave? This is their lair, where do you think they will hide if they are not here? Niu Eryi patted his head and said, yes! It's still thoughtful, don't be stunned, hurry up!

So they began to search for the secret room again. Xiao Zhuge clearly remembered that he found the third bedroom last time, but he just came in at that time, and he didn't look for it carefully. I have time today, so be sure to take a good look! I remember that the eighth master found this place at that time, but there was no result, and he fell asleep here that night. Could it be that there is no problem here? If there is a problem here, the secret room is here, just imagine, can the commissioner and Li Changji let the eighth master go? To deal with an extremely poor person, they will easily kill the eighth master, and they will definitely not let the eighth master go! However, the eighth master has been looking for these six bedrooms all night, and he only paid attention to this place after the last time, with the eighth master's carefulness and insight, since he has returned to pay attention to this place again, there must be something suspicious here! Besides, I checked 2, 4, and 6 last time, and I didn't find any problems, so it seems that the focus is on 1, 3, and 5! Hey, if you want to say yes, why don't you usually remember to exchange your views on the search with the eighth master! I'm in a hurry now, isn't it?

On the surface, this bedroom is no different from the others, except that this bed is different. The bed seems to have been carved according to the terrain, which is higher than the others, with two heads, one on the side of the mountainside and the other on the rock, which is some distance from the rocks, and this distance is empty. This empty space was made of several sticks, one end of which was placed on the stone bed, and the other end was inserted into the rock wall, and a wooden board was placed on top of it, which became a simple place to put miscellaneous items, and there was nothing else special. Xiao Zhuge looked left and right. Wherever there is doubt, I touch it with my own hands, but I still can't see any mystery.

Xiao Zhuge came to the fifth bedroom, which was even more mediocre and similar to other bedrooms. Xiao Zhuge also checked carefully and found no problems. At this time, Xiao Zhuge sat on the stone bed, put several bedrooms in his mind at the same time for comparison, except for the third bedroom is different from other bedrooms, nothing else can be found. Xiao Zhuge calmed down and thought very seriously, at that time, the commissioner's group of people obviously disappeared into the cave, and there were so many militias guarding around them, it was impossible for them to escape from this hole, there was another mystery in the cave, there was no doubt about it! The mechanism that these guys have painstakingly set up will not be easily discovered, and the IQ of these people is not idle!

While Xiao Zhuge was meditating, Niu Er came in. What do you think? Niu Er asked. It's not that easy. Xiao Zhuge said. Well, if everyone can find it, it won't be called a secret room, it seems that you still need to use your brain! Niu Er said. Let's not be discouraged, it will rain and smash a hole on the ground

, I don't believe I can't find it, it's nothing more than a matter of time. Xiao Zhuge cheered up.

Just as he was speaking, Niu Er "shh Xiao Zhuge listened quietly, there seemed to be a sound, but he couldn't hear what the sound was. He pulled out his gun and slowly slipped out of the dormitory along the wall, Niu Er following closely behind. They came to the bend and listened calmly, and waited for a long time, but there was no movement. Xiao Zhuge looked at Niu Er, which means, did we hear it wrong? Niu Er rolled his eyes, meaning to say, no, wait a minute.

Is there a voice, do you listen? Xiao Zhuge said softly. Niu Er pricked up his ears and listened carefully, well, it seemed that there was a voice, just in front. Niu Er motioned for Xiao Zhuge to go further. The two of them tiptoed forward with their guns in hand, and when they were almost at the entrance to the hole that led to the tunnel, they heard the sound coming from there! Listen carefully, it seems to say "Yangtze River, Yangtze River, I am the Yellow River, Yellow River Yellow River I am the Yangtze River". Xiao Zhuge looked at Niu Er, Niu Er blinked his eyes a few times, and a hot current rushed to his heart! "Sweet potato sweet potato, I'm a potato, potato potato, I'm sweet potato"! Niu Er carefully picked up the code. "Yangtze River, Yangtze River, I am the Yellow River, Yellow River Yellow River, I am the Yangtze River"! The voices in the tunnels got louder! "Sweet potato, I'm a potato, potato potato, I'm a sweet potato"! At this time, Xiao Zhuge also understood, and his voice was raised a little!

Master, teacher!

Light rain, stone eggs!

The two children crawled out of the tunnel. Niu Er and Xiao Zhuge hurriedly ran over, and Xiaoyu and Shidan threw themselves into their arms at once, crying loudly!

Suddenly, the mountain shook!
