Without aside, after a night's rest, the pace of the morning journey was noticeably quicker, and near noon we had reached the bottom of the waterfall, a little faster than expected.

Looking at the waterfall from a distance does not feel anything, only when we approach can we feel the majesty of the waterfall, in fact, when we are more than a mile away from the destination, we can already hear the rumbling sound of water, the drop is large, the water flow can be imagined, when you are under the waterfall, you have to shout loudly when you talk face to face, otherwise the other party will not be able to hear the content of the speech.

Due to the impact of the water, a pool of several hundred square meters was formed under the waterfall, and the water poured down into the pool, then calmed down and then flowed away along a river.

At the beginning, we also saw a waterfall in the small basin of the Xing'an Mountains, but the momentum of that waterfall was not the same as that of the tap water in front of us. If you really compare it carefully, the entrance to the tomb of General Wu Si is in the river, and the one in front of you is also in the waterfall, and the tomb of General Wu Si is very suspected of plagiarism.

A group of people stopped at the foot of the waterfall and we were ready to have our last lunch here before going down to the city. Lunch is contrary to the previous convention of boxed food, this time it is closer to nature, and it is thanks to Song Jin. Because the pool is relatively deep, everyone has to dive to catch fish in the water, and it is obviously more difficult to catch fish in deep water than diving, even if the fish here are isolated from the world and do not have an innate fear of humans. So Song Jin's recurve bow was temporarily transformed into a speargun, and a thin rope was tied to the arrow, which could not only recover the arrows from the society, but also reduce the resistance brought by the water body as much as possible. The position of the fish in the water is not accurate through the refraction of the water, but this is not difficult for Song Jin, and it will not take long for a few fresh fish to be in hand.

We made the original grilled fish, and although we didn't add too many condiments, we still ate it with relish.

After the meal, we took a short break to discuss how to get into the longan. I glanced up at the waterfall hanging overhead, and it was unlikely that I would fall down from the top, and if I didn't take the risk of falling straight into the pool. The dragon's eye is surrounded by waterfalls, the mountain is straight, and it is not easy to approach from both sides, thinking about it, I think the most reliable may be to climb directly from the bottom up, so that as long as you climb a certain distance, you will reach the dragon's eye.

I exchanged views with Lao Zhao and Kaoru Mochizuki, and they also agreed that it was more appropriate to enter from below up, but in this way we had to face another problem, although we carried a lot of equipment before coming, but because of the lack of estimation of the situation, only the diving suit was not prepared, and getting wet was inevitable, this is only one of them, and the other point is that we are not sure about the depth of the pool under the waterfall, and everyone's water nature is uneven, don't enter the dragon's eye, drown in this pool first.

Kaoru Mochizuki began to talk to Sasaki in Japanese, and we all listened attentively next to us, although we couldn't understand what was being said, so we had to pretend. At this time, the pit stood up and said disdainfully: "What's so difficult about this, I want to know the depth of the water, I'll know it when I dive once." When we were children, we bathed together in the big river, and the pit was a tyrant in the river, and the friends called it "buffalo".

Needless to say, the pit took off his coat, ran two steps, crossed one forward, and his body crossed an arc above the water, plunged into the water, splashed a splash, and stopped moving. At this time, Sasaki also walked to the waterhole, squatted at the water's edge for a while, and then returned.

Another exchange between Japanese, Kaoru Mochizuki said: "According to Sasaki's calculations, the depth of the water on the shore is three meters, and the center is estimated to be more than four meters. ”

At this time, the pit also floated up from the pool, and wiped a handful of water on his face: "Three meters on the shore, four and a half meters in the middle." ”

We were all surprised by this result, but how did Sasaki come to such an accurate conclusion after squatting at the water's edge for a while, and not seeing any measuring tools in his hand?

As a result, Kaoru Mochizuki relayed it to us, and it turned out that Sasaki didn't do anything when he squatted at the water's edge, but fiddled with the reeds in the water with his hands, but because he was facing away from us, we didn't notice it. To be exact, it was Sasaki who tilted the reeds in the water so that the reeds were more submerged in the water, so that he obtained several values, namely the angle between the reed and the water surface after tilting, the length of the reed in the water after tilting, the distance of the reed crossing the water surface when tilting, and then the depth of the water, that is, the length of the original reed submerged in the water, is unknown, and the result can be obtained by calculating the Pythagorean theorem.

Knowing the reason, we were dumbfounded, thinking that this Sasaki should not be a high school math teacher! Kaoru Mochizuki said that this is actually a skill of Japanese ninjas, and Sasaki himself is more fond of ninjutsu, so it is reasonable to know these things. However, in any case, this incident has once again deepened our impression of this Japanese man, who should not be underestimated.

The pit walked wet ashore, dripping water as he walked, and shouted in his mouth: "What's the matter, General Niu's water nature is quite good, right?" There was a smug expression on his face.

"Not bad, pretty good." I followed the words of the pit. Seeing him like this, I piggyback on him and added, "The ancestor is in charge of the heavenly court sailors!" ”

The pit was stunned for a moment, but he didn't react, Lao Zhao, Song Jin and Mochizuki Kaoru had already laughed and couldn't straighten their waists.

Now that we know the depth of the pool, it is also very helpful for the next step. Such a depth will not make some of us people who are not good at water at a loss, as long as they know a little bit of swimming, plus the assistance of others, there is no problem with the water depth of three or four meters. As for the clothes, no matter how deep the water is, it is sure to get soaked under the waterfall, but fortunately, although there is no wetsuit, the diving goggles are included in the equipment and brought over, so as to protect our eyes, and we can not distinguish the direction of the water under the waterfall because of the large and fast water flow. The rest of the equipment was put in the bag, sealed and piled up, and the only essentials were with them.

Zhang Xiaojun organized people to set up a small raft, which could carry four or five people at a time, and we stood on the raft in batches, and Song Jinzi and I and two other people boarded the raft as the first batch.

The raft moved steadily on the water, and soon approached the waterfall, and the raft seemed to shake a little. We tried our best to control the direction of the raft, while Song Jin prepared the flying tiger claws.

As a commonly used prop for climbing, the Flying Tiger claw is not exclusive to tomb robbers, once this object hooks a strong enough object, the claw of the barb will be tightened more and more, so as to ensure that the person in the climbing will not fall suddenly.

Forcefully full, as soon as he let go, the flying tiger claw went straight to the dragon's eye, and with a bang, it was firmly hooked in the rocks. Pulling two ropes vigorously, seeing that there was no loosening, Song Jin took the lead and climbed up along the rope, and after a few minutes, disappeared behind the waterfall.

We looked up, and we could only see the waterfall pouring down from above, and it took a while for Song Jin to poke his head out and wave at us below, meaning that we could continue.

Seeing that Song Jin had arrived smoothly, I grabbed the rope at random, stepped on the rock wall and climbed up, just two steps, the waterfall had already soaked my clothes, and I almost shook the strong water rush, so I had to hold on to the rope in my hand and didn't dare to let go, and moved up little by little.

I don't know how long it lasted, but I felt like I was about to faint from the waterfall, and when I began to wonder if we were doing it right, I finally climbed to the dragon's eye. I climbed into the cave in three or two, and I breathed a sigh of relief.

Looking out from the cave now, the waterhole is covered with layers of mist, and the colors of the rainbow are reflected in the sunlight, which is truly beautiful. The three of them stood on the raft and looked up at us. I waved my hand down and motioned for them to continue, and the pit grabbed the rope and crawled towards the dragon's eye.

Looking back at this dragon's eye, it is completely a natural cave, without any traces of artificial excavation, the ancient tomb may really be in it?

The light in the cave is relatively dim, and if you look into it for about ten meters, you can only see a black patch. Song Jin stood beside me, twisting the water on my clothes one by one, and I realized that my own clothes were also soaked, so I also began to wring the water in my own clothes, and the water flowed from my clothes to the ground, and then out of the hole along the ground.

After a while, the pit also climbed up, and the scolding began to wring the water in the clothes, and it seemed that it was also wet.

Then two other people climbed up one after another, also soaking wet, of course.

Seeing that the first few of us climbed up, the people on the shore pulled the raft back to the shore, Lao Zhao and Sasaki took three people on the raft and paddled down the waterfall, and in less than half an hour, several people also went up to the cave.

In the end, Kaoru Mochizuki and Zhao Xiaoxu took a raft together, and the last group rowed to the middle of the pool, and they also went up to the cave after ten minutes. The two eldest ladies both have long hair, and when they are wet with water, they are all wet and stick to their faces, so the scene is very sultry. Finding that I was looking at them, both of them turned around embarrassedly, and embarrassedly began to sort out their soaked clothes and hair, I also felt a little embarrassed, so I simply stopped looking at them, leaving them two with a natural "cloakroom".

Ten minutes later, the two of them finished tidying up and walked over to stand with us. I looked at Kaoru and Zhao Xiaoxu, and then at the dark cave in front of me, and this operation finally began in earnest.
