As soon as this idea appeared in my mind, I couldn't help but chuckle in my heart, the water monster has been said for a long time, and there are different opinions, whether it is the famous Loch Ness Monster, or the Taylor Lake Monster in the depths of the swamp, as well as the Kanas Lake Monster in Xinjiang, China, and the Changbai Mountain Tianchi Monster, where are these sacred, do they really exist, and if they exist, will they be aggressive, or how is the attack power? These questions are still unknown, but these places infested with water monsters have now been turned into tourist attractions, attracting thousands of curious visitors.

But this time we are facing a completely unknown realm, the depth and length of the cave are unknown, and for this kind of thing, I am afraid in my heart, first, my water nature is not good, and secondly, this water monster is too mysterious, and people always have an inexplicable fear of some unknown things.

In this way, with this apprehension, on the fifth day, the young man named Liu Yuan came to us again and told us that we could go.

Hearing the news, we immediately picked up the equipment and prepared to leave, the equipment was prepared before, all the emergency equipment is readily available, especially dry food, this time we prepared most of the compressed food, although the taste is not very good, but the size is small, easy to carry, enough for us to eat for two months.

Under the leadership of Liu Yuan, we left this quaint village, towards the southwest, after leaving the village, about seven or eight kilometers away, the road is quite flat, most of the surrounding are some gravel, except for some awkward, the rest is fine.

But further on, the terrain began to become steeper, forming a steep slope that sloped upward, and it was quite difficult for us to walk with heavy equipment on our backs.

Liu Yuan walked in front with a firewood knife in his hand, seeing that his steps were light and not chaotic at all, he must have often walked in this kind of deep mountains and old forests, and the surrounding environment was very familiar.

While walking, Liu Yuan turned back to talk to me from time to time, although this mountain road is rugged, we don't feel bored while walking and chatting.

After walking for a while, I began to hear the sound of running water, presumably about to reach the Tongtian River that Liu Yuan said, some forked streams gradually appeared in front of us, the stream water was clear and translucent, very beautiful.

Just after we crossed a forest, the scene in front of us suddenly opened up, only to see a winding and rugged river pouring down from the top of the mountain, the water is turbulent, looking at such a steep mountain, I can't believe my eyes, I can't believe my eyes, I can't believe the scene in front of me in disbelief, I can't close my mouth in surprise, such a slope, how can there be no waterfall? Instead, it has become a large river about a few tens of meters wide, and it is not possible to say that the water of this river is not affected by the laws of physics? No wonder Liu Yuan said that this river is too dangerous, and the fisherman with excellent water quality does not dare to approach it easily, this damn almost vertical river, who dares to hold a boat on it? Isn't that a shell lang entering the thatched house and looking for death?

At this time, Liu Yuan pointed to a crooked-necked tree in the distance, and said, "You wait for me here, don't walk around, the stones on this river beach are not stable, they are easy to loosen, and you will fall down if you step on the air, I will climb over first, help you tie the rope, and you climb up along the rope." ”

After speaking, Liu Yuan picked up a bundle of climbing ropes, and climbed up along the rocky beach on the riverbank, don't look at this Liu Yuan's body is thin, but his strength is not small, he is still in good shape with the mountaineering rope, and after a while, he climbed to the crooked neck tree, and after tying the rope, he signaled that we could go up.

I walked in front, grabbed the rope and began to climb up, at first it was not very obvious, until I climbed halfway, only to suddenly feel that the water in the Tongtian River is too turbulent, the splash can splash seven or eight meters high, plus there is no tall vegetation on the river beach, the mountain wind blows, layer by layer of water mist hits the body, at the beginning of the period can still feel a trace of coolness, after climbing to the middle position, that is cold, the water mist has almost soaked my clothes, in addition to the mountain wind blowing, the cold makes me shiver.

Liu Yuan sat on the crooked neck tree, waved his hands at us from afar, and shouted: "Hurry up, don't waste time here, there is still a long road ahead!" ”

I looked up, although I had climbed for a long time, but from Liu Yuan's location, there were still dozens of meters away, as the so-called Wangshan ran dead horses, standing under the Tongtian River and did not feel too far, this really to the time when I went to climb in person, only to find that I was really tired.

After we all arrived at the crooked neck tree, Liu Yuan collected the rope, explained some details to us, and continued to climb up, because there was no place to fix the climbing rope on it, so we could only follow Liu Yuan, slowly climb up, which stone he stepped on, we stepped on which stone, for fear that if one foot stepped on the wrong foot, the stone would loosen, and the whole person would fall.

This Tongtian River stretches for five or six kilometers, and it is all steep slopes that slope upward, it takes a lot of physical strength to climb up, and when we finally climb to the top of the Tongtian River, it is already evening, we have almost consumed all our physical strength along the way, and we just want to rest quickly, but as soon as I sit down, Liu Yuan hurriedly scolded, "Don't stop, this is not a place to rest, you have to go forward for a while." ”

Although I was extremely reluctant in my heart, since I asked Liu Yuan to be my guide, I could only choose to believe him, since he said that this was not a place to rest, then we continued to walk, and walked about two kilometers or so, Liu Yuan asked us to stop, set up a tent, and prepare to eat.

As time passed, the sky gradually darkened, Huzi and Wang Chuyi picked up a lot of dead branches from the surroundings, and prepared to raise a bonfire to heat and heat food, but as soon as the firewood was piled up, Liu Yuan hurriedly ran over, and hurriedly said, "No, you can't light a fire, and you can't have a light, we don't have a big tree to cover our current location, once the light is lit, the people in the village will know immediately, and they will definitely come up to stop you from going to find the ancient city." As he spoke, Liu Yuan kicked the freshly built firewood pile away.

Huzi was not happy when he saw it, his eyes widened, and he scolded, "Damn, if you don't order, don't order?" In this deep mountain and old forest, if you encounter some poisonous snakes and beasts, what should you do if there is no fire? ”

Liu Yuan was not in a hurry, and said, "Sleep with confidence, the place you were in just now was very dangerous, and now that you are here, there will be no poisonous snakes and beasts, at most they are small insects such as ants, and they will not be in the way." ”

Although Liu Yuan said this, neither I nor the Seventh Master believed it, after all, we had spent a lot of time in the jungle, and we were very familiar with the jungle environment, such as poisonous snakes, scorpions, and jackals and other fierce beasts, which could be infested at any time, how could Liu Yuan be sure that these would not appear in our location?

Although I didn't believe it in my heart, after all, Liu was far more experienced than us, so I asked him why he was so sure.

Then Liu Yuan turned around, pointed to the location where we came just now, and said, "Just now we were in the north of the river, and now we are in the south, this Tongtian River is also called the Yin and Yang River, which can separate Yin and Yang, the position we were in just now is the Yin Land, there are more poisonous snakes and beasts, and now in the Yang Land, those poisonous snakes and beasts will not come, most of the people here are birds, insects and the like, don't worry, no problem." ”

Saying that, Liu Yuan laid out the floor by himself, even took off his clothes, got into it shirtless, and then waved his hand at us, and said, "Hurry up and rest, Ming'er still has a long way to go, and the road behind is much more difficult than today." After saying that, he didn't pay attention to us anymore, and went to sleep first, and in less than half an hour, there was already an even snoring sound.

Although Liu Yuan had already fallen asleep, the four of us were still not at ease, and still followed the old method before, taking turns to stand guard.

Soon the night passed, and it was really like what Liu Yuan said, nothing happened in the night, except for a few bird calls occasionally, nothing else happened.

After waking up, eating, we followed Liu Yuan to continue walking, here has reached the end of the Tongtian River, far away to look around, the sun is rising, everything seems to be new, the place where the Tongtian River flows, formed a set of karst, landscape, caves and other natural scenery, now looking back, it is really steep and magnificent.

At this moment, I noticed that the colors on both sides of the river were different, and if I looked closely, the north side of the river was very dark, while the south side was full of sunshine and lush trees, and it was emerald green.

At this time, I understood why Liu Yuan said before that this Tongtian River is also called the Yin and Yang River, which can divide Yin and Yang.

I wondered, could it be that this river has something to do with the ancient tomb? How could there be such a miraculous sight? So I decided to take a closer look and hope that it would help us to go to the tomb in the future, and the Seventh Master and Huzi also agreed with my decision, so we began to observe the environment on the south bank of the Tongtian River.

After a few hours, as the sun continued to rise, the whole riverbank, as well as the slope of the riverbank, sprinkled with sunlight, I squatted down, from the angle of the slope, it was almost perpendicular to the sun's rays, and then looked at the north bank, the slope of the north bank turned away from the sun, although the sun rose high, but the sun was almost covered by the tall trees on the outer layer of the mountain, the whole north bank seemed very dark, I stood far away outside the slope, I could faintly hear the sound of poisonous snakes crawling, the dark environment of the north bank, it was simply a paradise for poisonous snakes.

At this time, Liu Yuan seemed to have been waiting a little impatiently, urging us to hurry up, shouting "Hurry up, there's nothing to see, this is a legend, the south bank is yang, the north bank is yin, yin and yang intersect, the sky is separated, you are looking at it for two years, and it will not change here, hurry up, let's rush to the outside of the fairy cave before Tianhe, otherwise there will be no place to stay overnight." ”

Under Liu Yuan's constant urging, we had to give up observation and follow Liu Yuan to continue walking, on the way the seventh master told me that in fact, many place names in our country are named according to the unique geographical environment, such as Huaiyin, Jiangyin, Hanyang, Shenyang, etc., and the climate on both sides of the river is indeed different, just like Wang Anshi's poem "Spring Breeze and the South Bank of the Green River" is about the climate difference between the north and south banks of the Yangtze River in early spring, and I don't want to do too much research, after all, we are here to fight, not to do natural investigations.
