After resting for a while and recovering their strength, the friends were ready to climb the mountain. Looking up at the flagpole beam, it must be hundreds of meters high, and it can be seen from the bottom of the mountain, which faintly means that it is unattainable.

Yang Wenbin took the lead and walked in front, and the friends followed behind him in twos and threes, grabbing the thorns and climbing upwards. The steep slope at the bottom of the mountain is estimated to be seventy or eighty degrees, and the thorns are about one person high, and there are no big trees to obstruct them. The feet are slippery and muddy, and it takes some effort to climb. Such a hill is not difficult for children who have lived in the countryside since childhood, but after climbing seventy or eighty meters, they are also out of breath. Several children also pulled out the distance between the front and back, separating the high and low levels of physical strength.

Slowly, the slope became steeper and higher, and it was estimated that it was still four-fifths of the way to the top. Looking back, the roads below the mountain are like long dragons, the Aomulun River is like a winding jade belt, the crops are like a green carpet, the cars are like beetles, and people are just like busy ants.

Here, there is a one-shaped mountain range in the east, west, north and south, and the four one-shaped mountains enclose a boxy, 100-mile plain, and there is a small hill in the middle of the plain, called Lonely Mountain. Although the lonely mountain is small, it is said that this mountain was misheard by the Kangxi Emperor as a pig mountain, and he was so frightened that he set off to leave the Khalqin palace the next day. These four mountains are not connected to each other, forming a mountain pass in the northeast, northwest, southeast and southwest respectively, which is called the four gates and four passes in ancient times.

It was from here that Cao Wei's army came north to conquer Wuhuan, and commanded the Wei army and Wuhuan army to fight on this plain on Dayang Mountain in the west. The Aomulun River flows from the southeast pass and from the northwest pass. At present, the 306 National Highway and the Weita Line Railway also enter from the southeast mountain pass and exit from the northwest mountain pass. And the two fortresses sandwiched between the two mountains are less than a kilometer wide, and there are dangerous peaks on both sides. It is precisely because there are four gates and four passes here, easy to attack and easy to defend, and there are plains and Ao Mulun River in the middle, so it has become the first choice of the Khalqin Palace. The peaks on all sides are towering, and the plain in the middle is a hundred miles, so it is called Lotus Mountain in the place. There are nine clear springs in the Lotus Mountain that flow continuously all the year round, and form a circular puddle on the mountainside of Beizi Mountain (North Mountain), so it is called the Moon Depression, and the overflowing spring water flows into the Ao Mulun River along the mountain stream. Therefore, this mountainous area is also called Jiuquan Lotus Moon Mountain.

At that time, the Nine Springs Lotus Moon Mountain was full of forests and wild beasts, and there were mostly grasslands and herds within a radius of 100 miles. In ancient times, the south of the mountain and the north of the water were called the yang land, and the Khalqin royal palace was located in the pure yang land backed by the Jiuquan Lotus Moon Mountain and facing the Ao Mulun River. According to historical records: when the flag was established, the forest was dense and the water grass was abundant. After the Kangxi Dynasty of the Qing Dynasty, agricultural reclamation flourished, and the indiscriminate felling of trees increased day by day, and the forest was seriously damaged. By the end of the Qing Dynasty and the beginning of the Republic of China, the forest was completely destroyed, and by the time of liberation, there were only about 60,000 acres of scattered sparse forest land, and the forest coverage area was less than 2%.

Suddenly, there were several screams in the air, and two goshawks circled halfway up the mountain, making a sharp whistling. Attracting the attention of these children. The higher you climb, the steeper the mountain becomes, and the mountain changes from earth to stony and is made of white limestone. The road is getting harder and harder, and at the beginning it was like flying, but now it can only move forward one step at a time. After climbing fifty or sixty meters like this, it was basically sticking to the cliff. But with the movement of the zigzag, slowly, it climbed more than a hundred meters. Fingers are crossed, the corners of the stones are pulled, and the feet are stepped on in the cracks of the stones, and if you are not careful, you will fall, and you must be careful.

At this time, Battle, who was opening the road in front, shouted, "Work hard, there is a four-eye hole on it." "I have only heard adults say that the Four Eyes Cave is a big cave on the halfway waist of Jiuquan Lotus Mountain, which is composed of four eyes. There are mountain springs and stalactites in it, which is very desirable. Now that they heard that it was coming, everyone was very excited, and the speed of the climb accelerated before they knew it. Battle in front of him took the lead in climbing into the four-eye hole, and everyone got into it one by one. The Four Eyes Cave is a natural large stone cave, about three meters high and two meters wide, large on the outside and small on the inside. The temperature inside the cave is significantly lower than outside the cave, which is very refreshing. A stalactite hangs down from the entrance of the cave, I don't know how many years. The Ichihiro mountain spring flows out of the stone crevice at the top of the cave and drips on the ground, forming a puddle, which is the portrayal of the water drop stone wearing. There are four small holes on the top of the cave, and the inside is so dark that you can't see the edge. The outermost two are slightly larger, the inner one is smaller than the other, and the innermost is only about 30 centimeters wide, allowing only a small child's body to drill in and out. The group was sweating profusely, and when they saw a cool place, they sat down on the ground, ate bread, and drank soda. After eating a few mouthfuls of bread and drinking a few sips of mountain spring water, Battle regained his energy.

Everyone set off clamoringly. At this time, Battle did not leave, and looked at the four holes in the hole of the four eyes.

"Let's go", Yang Wenbin urged, "I don't want to delay here for too long, hurry up and go up the mountain!" ”

"You say, what's in the four eyes?" Battle's curiosity grew, and he asked us and talked to himself.

"Wouldn't you know if you went in and had a look, how stupid!" Temur muttered.

"Let's go, go in and have a look. Timur, you enter the first, the Serigu, the second, and I the third; Battle, you're the skinniest, fourth. Yang Wenbin also moved his mind and hurriedly made an allocation. Actually, he was about the same as Battle, both skinny, but in order to straighten up this outstanding whimsy, he still made an allocation in his favor.

Siqin was the only girl left, and let her stay outside and guard her things. Just do it. According to the division of labor, the four people took off the satchels on their bodies, carried only flashlights, and went into battle lightly. Seeing that Temur and Seri Guchun had entered, Battle and Yang Wenbin had also climbed into the cave.

The hole that Yang Wenbin entered was slightly smaller, and he could barely climb with a cat's waist. It was very slippery, and there were some droppings of unknown animals, which smoked so much that people unconsciously covered their noses. The hole gets narrower and harder to climb. The faint light of the flashlight was only a meter or two. I didn't feel a little scared in my heart.

Suddenly, he felt a gust of wind accompanied by a few "squeaks", and a black shadow rushed towards him. With an instinctive flash, his head tilted to the right and stuck to the cave wall, and there were a few "whoosh" sounds in his ears, accompanied by a hot pain in his face. "Oh no, what's that?" Yang Wenbin shouted.

With the afterglow of the flashlight, seeing a few thin cracks on the dim rock wall of the head, Yang Wenbin knew that it turned out that there were a few bats flying by, and this must be the home of bats, so he disturbed the rest of the bats and flew them out in shock.

The inside is getting wider and wider, and it can already accommodate the body to stand up, and it is estimated that it has climbed into ten meters, and there is nothing new in it, so let's go back. Yang Wenbin's heart hadn't recovered from the fright just now, and he had the intention of retreating. He turned around and crawled back through the gap he had just made.
