"Your sixth master is lying on the bed, motionless, and dying. His face was covered with gauze, and blood seeped into the gauze, staining it all red. There were also two splints on one leg, and it looked like the leg was broken.

"Yi Qichong followed me into this room, stood behind me and said, 'Don't be too sad, although he is seriously injured, there is hope for his life. Why don't you go with me to the back mountain to see the patriarch, and ask his old man to come and heal your companion's wounds. Although I know a little bit of medicine, I don't know the bottom of my heart now. ’

"I turned around and asked, 'Who is the patriarch?'

"Yi Qichong said: 'The ancestor is my master, and he is also the mountain master here. ’

"I asked, 'What kind of mountain is this?'

"Yi Qichong said: 'This mountain is called Shouyang Mountain. Let's go, we'll go now. ’

I followed Yiqi out of the door, walked along the corridor to the corner of this small courtyard, and came out of a vase-shaped corner door, and suddenly opened up in front of me.

"The place outside the corner gate is a high platform, standing on the high platform and looking down, you can see the roof of the three or four halls, one floor is lower than the other, all built on the central axis along the mountain. There are a number of small halls on both sides of the main hall, which are also distributed according to the mountain steps. The roof of the main hall closest to the high platform is just flush with the high platform, and there are two rows of steps on either side of the high platform that lead to the side eaves of the main hall. On the side of the high platform against the peak, there is also a large hall, which is also lined up on a central axis with the main hall below. On the left side of the main hall is the courtyard we just came out, but on the right side of the main hall is a courtyard surrounded by a red wall, and there is a three- or four-story building in the courtyard.

"Yi Qi Chong led me around the main hall on the high platform, behind which there was a mountain path that led up to the peak behind the palace. We climb the ladder.

"Halfway up the mountain, the mountain road winds around the mountainside and turns behind the peak. We turned around and saw a higher mountain in front of us.

"The mountain road follows the bay between the two peaks, winds around the opposite hill, and juts between two huge rocks.

"As we passed through the stone gate made of two boulders, I suddenly felt a cool breath seep into my body, and I felt an indescribable sense of comfort. The meridians of the whole body are as if they have been ironed, and every inch of flesh and blood is very proper.

"The scene around us has changed.

"It's a narrow, deep canyon, with two rocky cliffs rising vertically and unclimbable. It was as if the mountain peaks had been split in half by a sharp axe here. The sky overhead turned into a long azure streamer.

"Half of the canyon is roads, usually streams. There are many strange flowers and plants growing in clusters along the stream, all of which are extremely verdant and beautiful.

"I asked Yi Qichong: 'Where did these flowers and plants come from, and why haven't I seen them elsewhere?'

Yi Qichong laughed, he looked back at me and said, 'These flowers and plants have been growing here for 10,000 years. ’

"I was amazed: '10,000 years?'

"Yi Qichong said: 'At least 10,000 years ago, these flowers and plants grew here. ’

"I asked, 'Why haven't I seen it anywhere else?' ’

"Yi Qichong said: 'The rest of the world has long been extinct. ’

I let out an "ah" in confusion.

"Yi Qichong continued: 'The climate of this canyon has remained the same as it was 10,000 years ago. The four seasons here are like spring, and there is no difference between winter and summer. The soil and rocks that make up the rock wall continuously release oxygen, so the oxygen content is high here. In addition, for unknown reasons, the air pressure here is much lower than outside the canyon, resulting in a large amount of transpiration in the stream and a lot of humidity in the air. These conditions are very similar to the climate in the Shouyangshan area 10,000 years ago. These flowers and plants used to grow outside the canyon, but in the past 10,000 years, external climate change has led to the extinction of all of them. And the flowers and plants that have evolved in the outside world over the past 10,000 years are not found in this canyon. ’

After listening to this, I was secretly amazed.

"We had been walking in the canyon for two or three meals, and I faintly heard the sound of rushing water in front of me, like the sound of a waterfall.

"When I walked to the place where the sound came from, I didn't see a waterfall, but I saw a black hole on the cliff wall on the right hand, and the black hole was diagonally deep into the ground, and the streams that flowed from both ends of the canyon flowed to this black hole. Listen to the sound of the water, it should be very deep inside.

"There are several strange trees growing around the black hole, covering most of the hole. In addition to the sound of water, there were also strange sounds coming from inside the cave, like the sound of people pinch the silver dollar between their fingers and blow it and put it to their ears when they check the authenticity of the silver dollar, but it was much louder than that sound.

"I asked Yi Qichong curiously, 'What is this sound?'

"Yi Qichong said: 'When I passed by here before, I also thought this sound was very strange, and I once asked the patriarch, and the patriarch said that there are ancient artifacts stored here, so we must not enter the cave in normal times. I don't know exactly what's inside. ’

"We came to the end of the canyon, where there was no exit and the same high cliff face in front of us. But on the right hand side of the cliff wall is a very narrow ladder, the ladder is in the shape of a folding ruler, zigzag, until it leads to the circular hole at the top of the cliff wall.

"When we entered the circular hole and went through the middle to the other end of the hole, I found that the hole was in the middle of a pinnacle from which a piece of the pinnacle had been dug out. There is a peak-shaped mountain in the shape of a treasure on the opposite side of the pinnacle. Between the pinnacles and the peak, there is a gentle valley with lush greenery and trees.

"There is a pontoon bridge between the two peaks, which is about a mile long. At this end of the pontoon bridge, there is a circular hole, and at the other end of the pontoon bridge is a cave covered by green trees, and there are two waterfalls on both sides of the cave that go straight to the bottom of the valley.

"Yiqi Chong led me up to the pontoon, and halfway through it he stopped and said, 'Look back. ’

"When I turned around, I saw the circular hole we had just passed, and the pinnacle. It looks magnificent. Then he casually said, "Good view." ’

"Yi Qichong listened and said, 'It seems that you haven't seen the wonders yet. What shape do you see that day?'

I was stunned.

"He saw that I didn't understand and added, 'Look at the sky inside the hole. ’

I took a look. He said, 'The hole is round, and the heavens are round.' ’

He pursed his lips and smiled, but without speaking, he walked straight on.

"When he got to the top of the bridge, to the mouth of the cave between the two waterfalls, he stopped again and said, 'Look back.' ’

"I looked back and saw a steamed bun-shaped peak peeking out behind the circular hole, which occupied most of the space behind the hole, and through the hole, only a crescent-shaped sky could be seen.

"I exclaimed, 'It's amazing, how the shape of the sky has changed. ’

"Yi Qichong said: 'Just in the middle of the pontoon bridge, which is the lowest point of the bridge, you can't see the mountain peak behind the hole, so you can see a circular sky, and the further you go this way, the higher the bridge deck, and the larger the area of the mountain peak behind you. At the entrance of this cave, you can only see a crescent-shaped sky. Walking from this bridge is like going through the process of looking at the moon from full to empty. When you go back, you can see the change of the New Moon from missing to round. That's why the bridge is called the Shuowang Bridge. ’

After he finished speaking, he turned around and pointed to the three words on the top of the cave and said, 'At the entrance of this cave, you can only see the moon shortage, so this cave is called the Shuoyue Cave.' ’

"I looked up, and sure enough, there were three big characters written on it: Shuoyue Cave. ”
