Leng Xuan shook his head strangely, and then increased his strength. However, Shimen remained motionless. Frowning secretly, he used his True Qi and slammed into Shimen. However, apart from shaking the dust off the stone gate, his attack left no trace on it. The result surprised him greatly. At this time, only Feng Lie's voice sounded: "No wonder those who were chasing you didn't come in. It is estimated that this stone gate blocked the outside." Leng Xuan agreed with this, he said: "This stone gate is It's a bit weird, and I don't know what material it's made of, it's extremely hard. However, although people outside can't get in, why can't I get out?" Feng Lie said: "Since the owner of this cave mansion built it back then This stone gate must be intentional. Boy, look around, maybe there is something in this stone house." Leng Xuan responded, and then carefully observed the stone house.

  This self-cultivation cave is built in the middle of the mountain, so the stone house is surrounded by mountain walls, and there are traces of polishing on it, which is very smooth. In addition, there is only a stone bed for cultivation in the stone house, and nothing else. Leng Xuan banged on the four walls, trying to find the hidden mechanism. However, after spending half a day, he did not gain anything. So, he locked his gaze on the stone bed. As the only existence in this stone house, the stone bed is very suspicious. Leng Xuan walked to the stone bed and reached out to wipe off all the dust covered on it. I saw a flat stone surface with a concave mark in the middle. There is nothing strange about this dent. I think it should be that the owner of this cave often sits cross-legged and cultivates on it. After a long time, this kind of trace is formed.

   After confirming that there was nothing strange on the stone surface, Leng Xuan moved his gaze to other parts of the stone bed. Soon, he discovered that this stone bed was excavated from a single piece of stone, and there was no mechanism in it. He touched his nose in distress, not knowing what to do. At this time, Feng Lie said: "Boy, don't be discouraged, look for it again, I don't believe that the owner of the cave house is useless to build this stone house." Leng Xuan nodded secretly, he looked at the dent on the stone surface, Quickly turning around in my mind. That dent is enough to show that the owner of the cave often cultivates here. Thinking of the word 'cultivation', Leng Xuan's heart was startled, and then he said to Fenglie: "Senior, this stone house is probably used by the master of the cave for cultivation and retreat. If so, then he built that strange stone gate. , maybe to prevent being disturbed."

Feng Lie slowly replied: "You do have some truth in saying that. But, according to what you mean, if this stone house is just a simple training room, wouldn't it be impossible for you to go out?" Leng Xuan said with a helpless smile. "I also hope that my guess is wrong, but this is the only possibility I can think of at the moment." Feng Lie pondered for a moment, then suddenly asked, "Do you feel short of breath now?" Leng Xuan replied Said: "No." After speaking, without waiting for Feng Lie to continue to say anything, he had already woken up: "Yes, since this stone house is sealed, how can there be air circulation." Feng Lie smiled: "It seems that You are not stupid either. As long as you solve this question, you might have a chance to go out."
