Next to the northernmost stone slab (the one near the north wall) was the entrance to the fox's den, to be exact, the mouth of the fox's den, which was still exposed after digging a foot from the ground, but it had been reduced by half, and had become a narrow gap, and it was dark inside, and I didn't know where it leads.

Xu Da raised his leg and stepped heavily on the stone slab in the middle, making a strange sound of "tom", and said happily: "The bottom is really hollow, and this slate is moving, I can see that I can get up." ”

Li Rui smiled slightly, and also tried to step on it, and got the same experience, and said: "This is easy to understand, these stone slabs are used to cover up the entrance steps of the underground cave below, and lime has been poured between the gaps between each other to cover up, if a layer of foot-high earth and stone mats is paved on top, who knows that there is a big secret hidden below?"

Gao Zixuan couldn't wait any longer, and shouted: "Two handsome guys, don't talk nonsense, hurry up, open these stone slabs, and see if there is an entrance to the cave." If you don't hurry up, someone will come again after a while, but it will be bad. ”

Li Rui listened to it in his heart, this girl really got to the point, now she is not afraid of anything else, she is afraid of someone coming, she has found the entrance to the cave, and she may find a large number of treasures at any time, if an outsider comes at this time, it will not be easy to deal with it, and said: "Well, look at how these stone slabs can be opened." Xu Da said: "There is a gap between the stone slabs, first insert the shovel into it, expand the gap, and then put the pickaxe into it and pry it up." As he spoke, he picked up the shovel next to him, first stuffed the tip of the shovel into the gap between the two stone slabs, and then moved the shovel back and forth, using the principle of levers to expand the gap between the stone slabs, and soon the gap was expanded to two centimeters.

Seeing the difference, Li Rui jumped out of the pit, holding the handle of the pickaxe, and stuffed the tip of the pickaxe blade into the gap. Xu Da raised his leg and stepped on it, stepping on half of the pickaxe blade into the gap. Li Rui smiled, held the handle of the pickaxe with both hands, and pushed it in the opposite direction hard, just listening to the "click...... pulled, and the slate had been slowly pried up. Xu Da didn't hesitate, stood behind the stone slab, bent down, grabbed the side of the pry up stone slab with both hands, lifted it up hard, and exhaled in his mouth. The stone slab rose in response, revealing a dark hole below.

Li Rui threw the pickaxe to the ground next to him, leaned over to look, and saw that the cave was dark and lightless, and there was a puff of dust and smoke wafting from it, and there was a faint smell of fox urine coming from it. Gao Zixuan stood next to him and looked in for a while, frowned, and said, "Why can't you see anything?"

Xu Da smiled, leaned the stone slab in his hand against the pit wall, took out a pocket flashlight from his pocket, turned on the power and shone it into the cave, and one or two steps were faintly visible, spreading southward.

Gao Zixuan shouted: "Oh, Xu Da, did you deliberately bring a flashlight?" I didn't know before, seeing that you came here empty-handed, I thought you were not interested in this treasure hunt, and I didn't expect you to be prepared." Xu Da smiled: "I didn't bring this on purpose, it's an EDC tool." Gao Zixuan said: "EDC, what is it?" Xu Da said: "The literal translation is something that you bring every day, in fact, it is a must-carry utensil, because you don't know when you will use it." Gao Zixuan nodded as if she didn't understand, and said, "This cave is also open, can you go in?

Xu Da said: "Don't worry, I'll see if there is oxygen in it first." So saying, he gathered a pile of weeds from the side, took out a lighter, took the branch that he had used to explore the way, put it in the fire and lit it, and finally returned to the pit and stretched the lit branch into the hole. There seemed to be wind in the cave, causing the flames on the branches to sway, but the flames were never extinguished.

Xu Da let go and threw the branch into the hole. The flaming branches fell down the steps of the cave, burned for a while, and finally shone in vain before disappearing.

"Is there a problem with the air in the cave?"

Li Rui asked uncertainly.

Xu Da snorted, turned around and picked up a fist-sized stone, and threw it diagonally in the direction of the extension of the cave. All three of them pricked up their ears to listen, and there seemed to be the sound of stones falling to the ground, but there seemed to be none.

Xu Da asked Li Rui and Gao Zixuan if they heard the sound of the stone falling to the ground, Li Rui said yes, and Gao Zixuan said no. Xu Da smiled wryly and picked up a stone again and threw it in. This time it was not bad, I heard the sound of the stone falling to the ground very clearly, and the echo was very muffled, as if it had fallen into an extremely deep space.

Xu Da nodded with satisfaction and said, "The air in the cave is fine, it should be all on the ground, and you can enter." Li Rui said: "Okay, I'll take the lead." Xu Da hurriedly grabbed it and said, "Don't, I'll come first." Li Rui knew why he rushed to come, firstly, he was a master of art and bold, and secondly, he was also taking care of himself as an elder brother, and he was a little moved in his heart, and said: "It's better for me to come first, anyway, there is no danger inside." Xu Da glanced at his figure and said with a smile: "You are so tall, can you get in?" or I'll come, don't rob me." As he spoke, he had already occupied the entrance to the cave.

Li Rui had no choice but to ask: "Then how are you going to get in?" Xu Da thought for a while and said, "I'll go in with my feet first, then squat, squat and slowly go in, and stand up when I can stand up." Li Rui asked again: "Is your flashlight bright enough? Do you need to make a simple torch?" Xu Da said: "I'll try it first." If you're fine, just find a few thick branches and burn them on the fire, maybe you'll really need them. After saying that, he squatted down, and his right leg slowly poked into the hole.

Gao Zixuan squatted on the edge of the pit very unladylikely, stared at him and slowly entered the hole, and muttered, "Xu Da, you have to be careful." ”

Xu Da ignored her, and only waited until he stepped on the steps in the cave before he smiled at her and slowly squatted down. He can't go down without squatting, because the steps here are still relatively shallow, and after he steps on it, his waist is level with the rocky ground, and he can't go down to the hole without squatting.

Li Rui and Gao Zixuan looked at him nervously, for fear that he would encounter any danger.

Xu Da was obviously very experienced, and after his head shrank into the cave, he did not rush forward, but stopped in place, holding a flashlight, and first observed the situation in the depths of the cave.

Gao Zixuan looked at him curiously for a while, then opened her lips and asked, "What did you see?"

Xu Da said: "The steps here are very high, the first step is almost a foot high. There is no bottom in sight. There is a lot of water vapor in the cave...... Now that's all I can feel, and I'm going inside. After saying that, he tentatively went down the cave, and after a while, he disappeared at the entrance of the cave.

Gao Zixuan couldn't see that he was a little flustered, and shouted nervously into the cave: "Xu Da, where have you been? Are you okay?" Xu Da replied indifferently: "It's okay, I seem to have finished to the end, this is a stone room...... Uh, it's so dark......" Gao Zixuan shouted, "Then do you see the treasure?" Xu Da smiled: "Not yet, I'm going inside......"

Li Rui was itchy when he heard this, and said to himself: "I will go down too." Gao Zixuan grabbed him and shouted arrogantly: "You are not allowed to go down." What should I do if you go down?" Li Rui was stunned and said, "You, you can do whatever you want, you can go down with us, or you can stay on it yourself." Gao Zixuan said: "No, I don't dare to go down, it's timid to stay outside alone, you have to accompany me outside." Li Rui couldn't cry or laugh, and said, "How old are you, and you're still afraid of this, you just guard at the entrance of the cave, I'll go down and take a look, and I'll be back soon." Gao Zixuan said: "No." Li Rui scolded: "Damn, then you can go down with me." Gao Zixuan said: "No, I'm timid, besides, if someone comes, cover this stone slab back, won't the three of us suffocate in the hole?"

Li Rui looked at the sun and said, "It's almost five o'clock, who is still running up the mountain at this time." Gao Zixuan grabbed his arm and said, "Anyway, I don't allow you to leave me, you have to accompany me to protect me." Li Rui couldn't cry or laugh, and said, "Miss, can you let me satisfy the curiosity psychology a little?" You also go down with me, and I promise that it will be fine......

As soon as he finished speaking, Xu Da's excited voice was already heard in the cave: "Hey, you two come down, the treasure has been found, it's in the cave, and there are still some things from the evil sect......"

Gao Zixuan was like crazy when she heard this, her face showed ecstasy, and she immediately stepped into the pit and shouted into the cave: "Xu Da, wait for me, I'll go down." Li Rui glared at her and said, "Hey, beauty, you seem to have just said that you didn't dare to go in, how can you have the courage to do it again?" Gao Zixuan smiled at him proudly and said, "Just now, now is now, now there is enough temptation, what else do I have to fear? You quickly hold me up and let me go down." ”

Li Rui was amused, leaned over to her side, grabbed her arm, helped her go down to the cave, and when she walked down the steps, he followed her.

As soon as Li Rui went down to the cave, he felt a yin wind blowing, even through his pants, he could feel the coolness, and his heart said that it was narrow and aggrieved, and the temperature was still low, Gao Zixuan, the flower-like delicate lady who grew up in the greenhouse, actually didn't realize it at all, which showed the attraction of treasure to her, of course, what she valued was not the value of the treasure itself, but the excitement of finding the treasure.

He quickly caught up with Gao Zixuan, helped her down the last step, and fell to the ground of this cave. Xu Da had already returned in front and was using a flashlight to illuminate the two. Although his flashlight is pocket-sized, it has six LED heads, and the beam of light emitted is pure and condensed, and it can illuminate a radius of about one meter in this hole where you can't see your fingers, and the effect is commendable.
