Looking at the yellowed leaves outside the window, Bai Qi was still practicing the songs he had made up hard. Although she wanted to write lyrics about her birthday, she couldn't think of a bad tune, so she had to make up a song that she had in mind. Today is September 23rd and Dad's birthday. Bai Qi thought in his heart how to sing this song to his father. At this time, the bell rang for the end of class, and the students in the classroom walked out one after another. Bai Qijian cleaned up and glanced up at the hanging on the wall

Zhong, said to himself, "Dad should be off work, right?" ”

Qili Village is a temporary village. A few years ago, it was a barren Gobi land nestled in the mountains. At that time, there were not many people living here, but when experts discovered a salt mine hidden deep in the mountain soil in the saddle not far from here, the government organized several teams of workers to dig salt wells in the mountains. Because it was more than 100 kilometers away from the nearest county seat, and the land was barren and uninhabited, the workers who could not return home because of transportation problems set up simple dwellings on a flat land more than five kilometers away from the mine for them to live in. Most of the workers who came here were from other provinces, and they had no relatives or friends in the neighboring counties, so they settled in this place and built villages. As the years passed, the population here grew, and the current village of Kiri was formed. And Bai Qi's father was one of these workers who opened salt mines. Bai Qi's family are all from other provinces, because Bai Qi's mother passed away early, Bai Qi's family has no relatives, Bai Qi's father often works in the mine, and has no time to take care of the children, so after receiving the job of digging salt mines, Bai Qi's father decided to take Bai Qi out of the province to live. Bai Qi originally went to school in a public primary school in a neighboring county, but later after having his own primary school because of the expansion of Qili Village, Bai Qi was taken to Qili Village by his father.

Walking on the way home, Bai Qi sang while thinking about her father's performance after hearing her blessing. Before he knew it, Bai Qi had arrived at the door. Look at the hidden wooden door. Bai Qi hesitated, didn't his father get off work? With speculation, Bai Qiyi pushed open the door and walked into the house, shouting, "Dad, I'm home!" But there was no father's voice in the house that answered Zivii. When Bai Qi put down his schoolbag, he saw his father's message on the table: Bai Qi, Dad is going to work overtime today, and he won't go home for dinner at noon, I have already cooked the lunch meal in the morning, you can just heat it up yourself. Dad didn't come back until 10 o'clock in the evening, and you don't have to wait for me for dinner, I told my neighbor Uncle Li that you would go and have dinner with them. Bai Qi read the note for a long time, she was a little lost but helpless. After simply eating her father's meal in the morning, she thought about how to spend the afternoon. It's Friday, so I don't have to go to class in the afternoon, so I have to stay at home, but my dad is not there. Thinking of this, Bai Qi sighed. She was bored and flipped out the birthday card she had prepared for her father, and after reading it carefully, she nodded with satisfaction. After Bai Qi finished his homework, he looked at the wall clock on the wall. "It's only four o'clock." She shook her head helplessly. Bai Qi thought about it and picked up the note left by her father for herself, looked at it, and took out the greeting card from the schoolbag and touched it, and finally she was about to put the greeting card back in the schoolbag, and then the idea popped out of her brain: Why don't I go to Yanjing to find my father now? This is sure to surprise him! Thinking of this, Bai Qi put the greeting card back in his schoolbag, and at the same time, took out the other books in the bag, and then closed the zipper. Carrying her schoolbag, Bai Qi thought about it and took out the two loaves of bread that the teacher had given her from the small drawer. After putting the bread in the school bag, I was satisfied that I closed the door and was ready to go.

Bai Qi and her father had been to the salt well a few times, so she knew how to get there. Bai Qi's trip was very easy, not only because of the cool weather, but also because of the excitement and happiness of meeting his father. She believed that she would be able to surprise her father.

Along the dirt and gravel road driven by the mine-carrying truck, Bai Qi soon arrived at the salt well. The Salt Well Mine is a circular mine with a diameter of more than 300 meters that has been excavated, and the mine is divided into above-ground and underground parts. The aboveground part has been basically completely mined because it was mined first. Experts speculate that there are still very rich salt mineral crystals underground, so the work of the workers at this time is basically carried out in the mine. Because of the topography, looking at the mine from up there is like seeing a huge pit. The deep pit is centered on the middle of the mine, which resembles a funnel-shaped well, so everyone vividly calls it a salt well.

Bai Qi walked along the winding dirt road towards the salt well in the middle. It was now afternoon work time, and Bai Qi saw some miners working on the mine in their work clothes. In order not to let them see herself, Bai Qi walked along the path behind a pile of mechanical tools, and until there was no one in her sight, she walked to the "wellhead" in the center with confidence. After arriving at the mouth of the well, Bai Qi found that the place was very large and seemed to be bottomless but there was a faint light below, she looked around again and found that there was a large undulating path leading to the well, and Bai Qi began to walk cautiously on this path.

As the depth increased, Bai Qi found that the light around him was getting worse and worse, and it was only when he walked forward that Bai Qi saw many dim yellow light sources. They're supposed to be the source of the light. Bai Qi thought about it in his heart and walked down for a while. At this time, a worker's voice came from behind Bai Qi: "Child, you are not allowed to come in casually, what are you doing here?" Bai Qi was startled, and she turned around to find a pale worker not far away. Seeing him walking towards him, Bai Qi hurriedly ran towards the deep mine road for fear of being caught. "No, don't run around!" The worker found that Bai Qi was disobedient and hurriedly chased after him. The two played a chase in the mine. The worker's speed was much faster than Bai Qi, and Bai Qi saw that he was about to be caught, and hurriedly rushed to a corner of the mine. The worker chasing Bai Qi saw that Bai Qi rushed through the corner and disappeared and hurried to the corner, he thought that Bai Qi was in the straight mine behind this corner, but he didn't see Bai Qi. At this time, a worker came from the other side of the mine, and he hurriedly asked, "Xiao Li, did you see a little girl in white just now?" So high. He said it and gestured with his hand to Bai Qi's height. Xiao Li shook his head: "This, I didn't see it, Brother Liu Xu, are you wrong?" Liu Xu was a little puzzled, but he couldn't figure out where the little girl was just now. He sighed and prepared to go back to work. At this time, Bai Qi, who was hiding in a rock crevice, breathed a sigh of relief, she realized that she couldn't go out now, so it was easy for adults to find out and be taken out of the salt well. Bai Qi turned around and found that there was a passage behind this rock crevice, but there didn't seem to be a yellow light source in front of him, but fortunately, there was a light blue light there, which made Bai Qi a little curious. She put her schoolbag on her back and walked cautiously towards the light source. Advancing in this passage, which was darker than the mine tunnel outside, Bai Qi was injured despite being very careful. Bai Qi came to an undulating place of unknown height. Looking at the dark below, in order to see if he could go down, Bai Qi had to come up with a way to measure how deep it was below. She grabbed a prismatic ore with her left hand, and also grasped the stone on the other side with her right hand, and then she stepped on a bulge of the soil wall below with her left foot, and then put down her right foot to try the height of the earth wall here, but at this moment, the place where her left foot stepped down, Bai Qi's body slid down, and Bai Qi's left hand was directly cut out of a wound. Fortunately, Bai Qi's foot stepped directly on the soil below, and she breathed a sigh of relief. Bai Qi felt a little pain in the palm of her left hand, but she dealt with it briefly and walked forward.

In the process of advancing, Bai Qi found that there were no traces of excavation here, and it seemed to be a natural formation. Bai Qimo walked for about ten minutes and then came to a relatively open flat land. It was illuminated by a pale blue light source, and the translucent salt ore overhead was lit up. There is a large stone slab on the flat ground, and the light blue light emits from the stone slab. "Slate?" Bai Qi muttered to herself, and she came to the large uneven stone slab in the center of the flat ground. She looked curiously at the slate, which was about four square meters in size. She found that the slate was divided into above-ground and lower parts. The upper part is uneven but there is a huge pit in the middle, and the lower part has a series of passages through the stone slab. The composition of the slate was strange, and Bai Qi found a lot of white substance, but she didn't know what it was.

Bai Qi looked at the slate in a daze for a long time, and then she found that there was an unusually beautiful checkered stone embedded in the lower part of the slate. Bai Qi was worried that there was nothing good to give his father as a gift, but now he had a good stone. It just so happens that it can make sights for his father. Bai Qi didn't still want to hold the stone directly with his right hand and pull it out hard. But Bai Qi couldn't pull it out with all her strength, she felt that this prismatic stone should be connected to the slate, so she couldn't pull it out.

Bai Qi wanted to give up, but she still didn't give up after taking another look. So she put her right hand against the slab and reached out her left hand to grasp the stone. This time the stone was pulled out directly, Bai Qi didn't expect it to be so simple, but she didn't think about it in a hurry. Bai Qi looked at the stone in his left hand seriously, this stone also emitted a pale blue light like the stone slab. She noticed that the back of the stone was stained with water. Bai Qi found that the wound just now was bleeding again, and she simply treated the wound and wiped the blood off the stone before she was relieved. After wiping it off, she looked at the stone in her hand and said to herself, "Why does it feel dark?" Bai Qi felt that it was his own illusion and didn't think much about it. It's time to go find Daddy," Bai Qi muttered to himself in his heart.

With the faint light emitted by the stone, Bai Qi began to walk back. At this time, there was a faint sound of running water in the cave behind Bai Qi, but she didn't care, just continued to walk back.

In the process of rushing back, Bai Qi hummed his song softly, but unexpectedly found that the stone in his hand emitted an even more dazzling light than just now. Bai Qi was a little surprised, but she quickly stopped thinking about it and continued to hurry. Because of the help of the light source of the stone, Bai Qi quickly returned to the starting point just now. This time, she carefully observed the surrounding of the mine, and after making sure that there were no miners working, she made sure that there was no work in the mine, and made her way to a brightly lit mine.

Bai Qi, who didn't know the way, heard his father's voice after wandering around the mine for a week. She happily ran into the downward mine.

At this time, Bai Qi's father, Bai Jianshu, was resting and chatting with the workers, and they were holding the coarse dry food they had brought from home. While sending it to his mouth, he told his own story. "Jianshu, do you let your daughter be home alone and not worry about her running around to play?" Lao Xu preached while chewing on the food. Bai Jianshu didn't think much about it and said directly: "What are you thinking about, Old Xu, my daughter is not like you think." Lao Xu heard this, and just wanted to speak, but was interrupted by a voice: "Dad, Bai Qi came to see you!" Everyone who was still eating looked at the entrance of the mine. Bai Jianshu watched his daughter walk towards him with a bewildered expression. Lao Xu laughed directly and said, "Look at Jianshu, I'm right, haha!" Bai Jianshu ignored Lao Xu, and at this time he was more concerned about why his daughter came here. Bai Jianshu put down the food in his mouth, stepped forward, picked up Bai Qi, and walked towards the workers. After Bai Qi sat down, Bai Jianshu asked his daughter seriously:

"Bai Qi, why did you come here, don't you know how dangerous it is under the salt well? Didn't Dad say that he was at home waiting for Dad to come home? ”

"Dad, I'm here to surprise you." Bai Qi replied to his father seriously.

Bai Jianshu originally wanted to teach his daughter a lesson, but when he thought about it, he couldn't blame the child. Bai Qi looked at these workers, whose faces were pale due to long-term underground work, and felt a little lost in her heart, but she still greeted the workers happily, and everyone praised Bai Qi for being polite.

After everyone sat down, Bai Qi coughed and signaled everyone to be quiet, and everyone who was originally lively stopped. Together, they looked at the little girl and wondered what she was going to announce. Bai Jianshu looked at his daughter and didn't say anything. Bai Qi stood up slowly, and she said in a very formal voice: "Hello uncles and brothers, I want to tell you something here today, today is my father's birthday!" The workers present applauded when they heard Bai Qi's announcement. After Bai Qi finished speaking, he carefully took out the greeting card he had prepared for Wen Qin and the stone just now from his bag and handed it to Bai Jianshu, and said seriously: "Dad, this is my birthday gift to you, you have to put it away." Bai Jianshu was very pleased, he carefully took the gift from his daughter's hand, and his eyes were instantly moist when he fell asleep. Dad, what's wrong with you? Bai Qi noticed the change in his father and hurriedly asked. Bai Qi's father, Lu, hurriedly lowered his head and said, "It's okay, it's okay, Dad just has a little dust in his eyes, it's nothing." After everyone was quiet again, Bai Qi began to call again: "I also prepared a birthday song for my father today." Now let me sing it to you. After Bai Qi finished speaking, everyone instantly fell silent. Because they know that every child needs to be respected when they are serious. Immediately after that, Bai Qi began his own performance. "Autumn Moon Mountains and Seas ......" Bai Qi's singing voice is not as beautiful as that of professional singers, and her singing voice intoxicates everyone present, after all, she has not heard any songs after working in this dim mine for so long. After singing the song, people praised Bai Qi's filial piety and talent.

The break is coming to an end, and everyone is back to work. Bai Qi's father wanted to send his daughter home, after all, it was already half past seven in the evening, and it was not safe to let Bai Qi go home alone. Bai Jianshu, who was helpless, had no choice but to ask for leave and accompany Bai Qi home together. But at this time, Bai Qi's father noticed that something was wrong. There is the sound of running water in the mine, and it sounds like a lot of water. Bai Jianshu put down his daughter and walked to the intersection of the three mine roads alone, and found that a large amount of flowing water was coming down from the mine above, because the terrain of the other mine crossing was low, so most of the water flowed to that side. If this continues, the entire mine may be filled with water! Bai Jianshu realized the seriousness of the problem and hurriedly went back to his mine to find a worker. At this time, the workers in the mine also heard the sound of running water, and people were a little flustered, Lao Xu hurriedly said: "Don't think about it, Jianshu has gone to observe the situation, we should wait for his news." After a while, Bai Jianshu appeared in everyone's field of vision. He hurriedly summoned the workers to explain the problem of running water. "The salt well may be filled with water, everyone hurry up and go out first." After listening to Bai Jianshu's words, everyone also understood the seriousness of the matter, they put down their tools and climbed up, and Bai Qi also followed closely behind his father and walked back. As everyone walked up, they found that the amount of water pouring into the mine was getting bigger and bigger, and the construction site had been flooded. "No, Tujia hurry up!" One of the workers shouted anxiously. The crowd also quickened their pace. When everyone went up to the mouth of the pit, they found that the mouth had been blocked by the wooden frame and some debris washed down by the water, and they could not go up. The crowd was trapped under the strong mouth and the water was still increasing. "Why are salt wells filled with water? It stands to reason that there are no land and water channels in this area! ”

"Could it be heavy rain?"

"No way, the annual precipitation here can't be so much!" A few of the more experienced workers carefully climbed to the mouth of the pit and tried to push the wooden frame out of the hole by hand, but after trying a few times, they shook their heads in disappointment. Just when everyone was desperate, the wooden frame on the pit suddenly loosened and fell down directly, and the amount of flowing water increased instantly, and Bai Qiyi and his party were directly washed away by the flowing water. "Dad" Bai Qi was rushed into the water as soon as he shouted. In her gradually blurred vision, she saw her father trying to swim towards her, but the distance between the two was getting farther and farther away. At the moment when Bai Qi was about to close her eyes, she saw the stone she had given her father in front of her, sinking into the water with herself......
