A river naturally has an upstream and a downstream. "Words, feelings, first, http://www.Klxsw.com

The upstream must be on higher ground in order for the river to flow slowly downstream. If the distance between the upstream and downstream is short, and the drop is large, the flow rate of the river will be very fast, and if the distance between the upstream and downstream is long, the flow rate will be relatively slow.

At present, above this underground river is the Green Duck River, and the water flow of the underground river is so slow, it can be seen that the upstream is unlikely to be somewhere in the nearby river, otherwise, with this difference between the river surface and the underground river, the flow rate of the underground river cannot be so slow in a short distance

Therefore, going upstream is a bit impractical

There are fish living in the underground river, presumably there is a large environment suitable for fish to live nearby, such as a cave in the river.

Therefore, it is more reliable to go downstream

Thinking of this, Xia Fei quickly made up his mind and took Cai Yinxiong downstream.

The water quality of the underground river is quite good and relatively clear, but because of the extremely poor light, the visibility is about less than one meter. Therefore, Xia Fei and Cai Yinxiong moved forward very slowly, because they were afraid that if they traveled too fast and missed the nearest exit.

In this way, as the two slowly groped forward, time passed minute by minute.

After about ten minutes, Cai Yinxiong felt a little out of breath, firstly, because he was old, and his body and energy were not as good as Xia Fei, and secondly, he was originally a split personality, so it was difficult for Xia Fei to be so focused.

As a result, he couldn't help but get a little flustered, and he looked helpless in the water, and he didn't know whether it was better to walk back or try to float to the surface.

Xia Fei felt that the water flow around him suddenly became disordered, and turned to look over. I happened to see Cai Yinxiong's panicked face. Between the lightning and flint, Xia Fei took out a silver needle and pierced it into the Yunmen acupoint, which was located in his trachea and throat and crossed out of his armpit. Then he grabbed Cai Yinxiong's arm and followed the inside of his upper arm. Pierced into the two acupuncture points of Tianfu Xia Bai, then stabbed down to the Qi Ze acupoint in the elbow, and finally along the inside of the forearm, all the way to the meridian canal acupoint, Taiyuan acupoint, Yuji acupoint and Shaoshang acupoint at the end of the thumb and finger......

This series of nine needles, even though it is underwater, is still done in one go, without the slightest condensation

After the lungs were unobstructed, Cai Yinxiong's internal breath instantly stabilized. He glanced at Xia Fei gratefully, after all, if it wasn't for Xia Fei, he would definitely fall into the pain of drowning.

The two continued to move forward, and after about three or four minutes, a bright light appeared in front of them, more than ten meters away, hazy, but it was extremely surprising.

Xia Fei took the lead and rushed towards the bright light.

Sure enough, this is a hole with a diameter of about two or three meters, and outside the mouth of the cave is the rock formation under the bottom of the Green Duck River. It is about four or five meters deep from the surface of the river. Faintly can be the moonlight in the sky.

Xia Fei dragged Cai Yinxiong, whose face was a little purple, and swam to the river. With a "poof", the two of them came out of the water. The clear and cold river breeze instantly poured into the noses of the two of them, burrowing into their lungs, and a sweet smell made them feel relaxed and happy.

"If you haven't experienced holding your breath for a long time, who would have realized that being able to breathe freely in the wind is such a pleasant thing," Xia Fei couldn't help but sigh.

At this time, Cai Yinxiong's eyes were faintly full of fierceness, and his voice became low and sharp: "Who are you?" Why am I here with you? ”

What happens when it sits down?

Moment of truth. How do you feel like you've suddenly changed people?

Obviously, Cai Yinxiong's other personality has popped out again

Xia Fei was depressed. He glanced at him and said, "Are you stupid?" Still stupid? Still stupid? I don't know who I am, how did you follow me into the water? ”

Belch......

Cai Yinxiong's other personality has obviously never thought about this problem. I was instantly stopped by this question

Yes, if I don't know who this kid is, why would I appear in the river with this kid and soak in the river? And what's even more terrifying is that this kid is still holding my hand?

Dwarf, I'm going, this picture is so beautiful, Cai Yinxiong found that he couldn't look at it directly

So, he decisively shook off Xia Fei's hand, looking very disgusted

What kind of expression do you have?

Xia Fei pointedly at the river and said, "Why don't you look in the mirror?" Damn, you look like this, and you still have the face to dislike others? ”

When Cai Yinxiong heard this, he immediately exploded and was about to go crazy, but Xia Fei no longer had the patience to play with him.

I saw Xia Fei take a deep breath and said, "Okay, since you dislike me so much, let's play by myself, I'm going to go diving bye."

After saying that, he plunged into the bottom of the water, leaving only a splash.

Cai Yinxiong was messy in the water for a long time, looking at the place where Xia Fei disappeared, he was stunned, there were a few things he couldn't figure out how to write: Who was that kid just now? How did you know him? Why did you soak in water with him? Why did he hold his hand? And it seems that he didn't seem to refuse before......

"Ah......" Cai Yinxiong let out an unwilling roar, but he didn't know how to relieve the confusion in his heart, he also tried to lower his head and go to the water to find Xia Fei's traces, but unfortunately Xia Fei's diving speed was very fast, and he had returned to the underground river from the rock cave that he had just come up in just now. So much so that after Cai Yinxiong lowered his head, he found that Xia Fei's shadow could no longer be found underwater

Shorty, I'll go

In this way, Cai Yinxiong is even more skeptical about whether the scene that happened just now is true? Could it be ...... Is it a hallucination?

The more Cai Yinxiong thought about it, the more he felt that there was such a possibility, which can also explain why he appeared in the water, because he had hallucinations before

He pondered the question as he swam toward the shore. Of course, there can be no answer to this kind of question, and when he arrived on the shore, he lay down on the beach on the shore, looked up at the bright stars in the sky, and muttered, "I don't seem to have seen the stars for many years."

Suddenly, he was shocked in his heart: "No, it seems that I was in the underground base before, so I feel like I haven't seen the stars for many years, but why did I suddenly appear outside the base now?" What the hell is going on? What happened in the base? ”

Just as he was thinking wildly, in a small forest not far from the shore, there was a sudden burst of gunshots, which set off the silence of the night and made it extremely cold. To be continued
