When we entered the grassland, the weather did not seem to be very good, Hulunbuir grassland belongs to the northern temperate semi-arid region, the climate is cold and dry, the winter is long and the summer is short, the spring is windy and sandy, but the summer is the same, at this time I can't help but be very hot, it is very uncomfortable, even Abu began to shout: "I'll go, this good grassland, why is it so hot, it is said that this place with grass should be very humid, how can it become like this!" ”

I listened and said: "This is nothing, in winter, the Hulun Lake we are going to will freeze, and the lake will be frozen from the beginning of November, until the beginning of May of the following year, the ice thickness can reach more than one meter, it is a lake with a long freezing period in China, so you should be glad that it is summer instead of winter!" ”

Abu listened and said, "That's still a hot spot!" ”

The second uncle also seems to have done his homework on Hulun Lake, and said: "Hulun Lake: also called Lun Pond, the locals are used to calling it Dalai Lake. Pen & Fun & Pavilion www.biquge.info

Hulun Lake is the fifth largest freshwater lake in China and the largest lake in the Inner Mongolia Autonomous Region, located between Zhalai Nuoer District and the New Balhu Left Banner and the New Balhu Right Banner, so ah, if we want to get there, it will take time! ”

In fact, Hulun Lake is a tectonic lake formed by crustal movement, and the source of water replenishment of Hulun Lake is: in addition to the direct bearing of atmospheric precipitation on the lake surface, it mainly relies on surface runoff and groundwater recharge; The main rivers that flow into Hulun Lake are the Wuersun River, the Krulun River, and the Dharan Oromu River; There are more than a dozen springs in the lake, and a small amount of groundwater is recharged.

The change of water quality of Hulun Lake mainly depends on the increase or decrease of the water volume of the lake: when the water volume of the lake increases, the water level rises, and it becomes a drainage lake, which is a pool of "living water", the salt content decreases, and it belongs to a freshwater lake; When the water volume of the lake continues to decrease, the water level continues to drop, it only swallows but does not spit out, and even cuts off the connection with the outflow river and becomes an inland lake, becoming a pool of "stagnant water", the salt content of the lake water will increase, and even become a brackish water lake.

Secondly, Hulun Lake is an irregular oblique rectangle, and the long axis is southwest to northeast. The west shore of Hulun Lake is undulating mountains and handsome cliffs; The east and south shores are flat and open. The bottom of the lake is muddy and relatively flat. In addition to atmospheric precipitation and groundwater, the water supply of Hulun Lake mainly comes from the Krulun River, which originates in eastern Mongolia, and the Wuersun River, which connects Lake Bell and Hulun Lake.

We don't know how long we walked on the grassland, chartered a car, and then found a yurt to live for a few days, probably because we wanted to play for a few days, we were all playing while looking for the so-called tomb of Emperor Yuan Kangding, until one day I and the second uncle Abu and the two of them arrived at the lake, we were here to play, and did not say that we would be able to find the so-called imperial tomb, but when we wandered in the grassland by the king lake, Abu fell under his feet, as if he stepped on something.

Abu immediately sensed that something was wrong and said, "Why is the soil here so sent?" I'm going, I'm still falling! ”

I hurriedly walked to Abu's side and grabbed Abu, it seems that there is indeed a situation here, and our location is far away from the place where the herdsmen are herding cattle and sheep, and there is no one to be found in the look, and we have already prepared some tools in our backpacks, although there are not many of them, but at least they can open a thief hole.

I pulled Abu and asked, "Abu, try to step on it, is the soil soft?" "I asked this mainly because there are many wetlands around Hulun Lake, and I ruled out that it was just a wetland, so I asked.

Abu tried to stomp his foot down, and said, "It seems that there is a situation, the soil is dry underneath, don't talk about it, pull me up!" ”

Abu held on to the edge, I stepped hard to pull him up, only to see that Abu's body had stepped out of a hole below, and the hole looked like it had been dug out, the master saw this situation and hurriedly ran over, my father followed, Li Yahong also walked over.

Anyway, Li Yahong is afraid that this time I am not only here for the Ming weapon, I am afraid there are other purposes, but we didn't care, the second uncle first took out the sapper shovel, and then shouted: "Let's go down and take a look, this should be a thief hole that has been opened!" ”

"What, there's already someone here?" I was surprised.

"It should be, otherwise how could the soil at the entrance of this cave be so loose, it must have been beaten out before!" The second uncle replied.

"Then what are you rubbing, let's go down and see!" My dad said.

The master didn't say anything after listening, and jumped directly into the hole, the grass next to the cave entrance was jumped down by the summer night and fanned it, we didn't have time to speak, we couldn't see the figure of the master, only heard the sound of the soil falling down, I tried to shout the master, shouted: "Master, can you hear it?" What's the situation below! ”

After a while, I heard the master reply: "It's not very deep, you guys come down!" ”

We all breathed a sigh of relief when we heard the master's voice, and the second uncle said to us: "Then in this case, I will go down first, and Abu and Ayuan will come down later!" "We answered.

The second uncle threw the sapper shovel down first, and slid down the hole, and we did the same, after throwing the backpack down, we all jumped down, and only after going down did we look for a flashlight, at this time I could only see the sunlight shining in at the entrance of the hole, but I couldn't see the situation inside, and I could only see the flashlight.

When we turned on the flashlight, we saw that it was like a tunnel inside, and it looked like a tunnel left by those who were mining, and it could only be said that this tunnel was very spacious, and when I shone the flashlight into it, I saw three pairs of bright eyes staring at me, and I was scared at first, but if I looked closely, it was the master and the second uncle and Li Yahong and the three of them.

I whispered, "Master, this tunnel shouldn't be a tomb!" ”

"No, it's the thief hole made by the person in front, it seems that you should be able to go to some tomb if you go in!" The master didn't worry about anything, and replied loudly.

"Come here, don't stay there!" The second uncle said to us at this time.

When we walked over, we found that the soil in the cave did not know what to do, I also deliberately touched the mud next to it, did not feel a trace of moist breath, it seems that the hole has not known how long has been knocked out, this was originally by the lake, I didn't expect the soil in it to be so dry.

Abu looked forward and said, "This hole is a bit long, I can't see the head, and I can't get in?" If this has been stolen, I'm afraid there won't be anything left, I think we should find a new place to go in, in case it's not the tomb of Emperor Kangding, isn't it in vain to go in? ”

The master said: "It should be his tomb, whether it is stolen or not, I have to go in and have a look!" "The master still insisted.

While we were still discussing, I shone my flashlight in front of me, and I saw a person sitting under the mud wall.
