Bang bang bang!

A few fist-sized rocks smashed down.

Xuan Zhen raised his arm, and then blocked it with his robe.

Fortunately, the force of the stones, which was not very large, was all blocked.

The cave is too narrow for any unexpected situation to be dangerous.

Hyun Zhen urged: "We have to get out quickly, the rocks on it are too scary." ”

Lu Fanzhou groaned and looked outside the cave.

At this point, the flute seemed to stop.

"Okay, let's go down."

As he spoke, he grabbed the entrance of the cave and leaped forward.

The entrance to the cave is two meters above the ground, and the ground is covered with green grass.

The grass was soft, and Lu Panzhou was still in the position where he landed, laying a thick layer of grass mat.

So the landing of several people went smoothly.

Even Duan Jingzhi, who has very little strength, landed steadily.

After Chongning jumped down, he looked around, both familiar and unfamiliar.

This is the lower reaches of the underground river, and he has not been there.

But overall, it's not much different from upstream.

The underground river stretches out all the way out, with a long and narrow space that doesn't know where it flows.

The crowd I saw at the entrance of the cave just now has disappeared.

It was empty, and there seemed to be nothing but the mighty river.

Sun Yi asked curiously, "What about those people?" Why is it gone? ”

A group of figures, suddenly disappearing, always looks very strange.

Duan Jingzhi said: "It was obviously there just now, but it disappeared all of a sudden?" Is that a human or a ghost? ”

Sun Yi shuddered, "I'm cowardly, don't scare me." ”

Lu Panzhou looked over there, his face was cautious, and said: "This underground river is too weird, let's be careful." ”

However, it is impossible to say that a group of people disappeared inexplicably.

Chongning asked, "Further down, have you ever been?" ”

You Lanfeng said: "In the past, we probed, and the space over there is getting smaller and smaller. ”

According to his description, the entire space of the underground river is narrow on both sides and wide in the middle.

It looks like a spindle.

Chongning asked, "Have you seen the last place where the underground river flowed?" ”

You Lanfeng frowned slightly, "The river flows out at the end, and it should be a hundred rivers entering the sea." The location over there was steep and we didn't go to see it. ”

Lu Fanzhou's eyes lit up and said, "What Chongning means is that behind the downstream exit, there will be another space?" ”

Because in the upper reaches of the underground river, the most source is connected to a valley of flowers.

The whole burial chamber seems to be very symmetrical.

There is even the construction of a mirrored burial chamber.

At the back of the upstream, there is a valley of flowers.

There should also be a space at the rear of the downstream to correspond.

You Lanfeng groaned and said, "Then let's go over and have a look?" ”

Chongning feels that at the downstream exit, there must be a space connected.

It was impossible for the figures to disappear out of thin air, they must have entered that space.

Lu Panzhou and the others took a short rest, and then walked down the underground river to the downstream.

The river was wide at first, but it became narrower as you went.

This is almost similar to the situation upstream.

Everyone walked very slowly and cautiously.

Lu Panzhou suddenly stopped and looked at the surrounding stone walls.

Chongning looked over and was surprised to find that there were many arrows nailed to the stone wall!

The arrows seemed to open from across the river, with great force.

Each arrow pierced several inches into the stone wall.

You Lanfeng's eyes narrowed slightly, "Look at the riverside." ”

Chongning shone a flashlight and found that there were many scattered bamboos by the river.

The bamboo is pitch black, horizontal and vertical, scattered all over the ground.

Sun Yi was puzzled and said, "Why are there so many bamboos?" ”

Lu Fanzhou said: "That's not bamboo, it's a bamboo flute." ”

Chongning took a closer look, and sure enough, there were regular holes in the bamboo.

Here are some broken bamboo flutes.

Duan Jingzhi's eyes flickered, and she said, "Could it be that the flute we heard just now was made from here." ”

Lu Fanzhou groaned and said, "Look around, there are still traces of fighting. It should have been the group that triggered a sonic kill mechanism. ”

As he spoke, he reached out to the wall and touched it.

There was no blood on the arrows or on the stone walls.

It seems that this group of people has escaped this mechanism.

It also shows that the ability of these people is not trivial.

Lu Panzhou looked at the dark front and said, "Let's be careful and keep walking." ”

After about ten minutes of walking, the river became extremely narrow and could only accommodate one person to walk forward.

Chongning seemed to have stepped on something under his feet, and when he picked it up, it was a cigarette butt.

"Cigarette butts?" When Duan Jingzhi saw it, she said, "We don't have any smokers here." ”

Lu Panzhou and his party did not smoke at all.

It was clear that the cigarette butt had been left by the group.

Chongning pinched it, and there was still temperature on the cigarette butt, indicating that those people had not gone far.

You Lanfeng suddenly fell to the ground, sniffing the dirt.

"There were at least ten people, and they just left."

Chongning was a little surprised, "More than a dozen, so many?" ”

What he encountered, Zeng Qianfan's group, was only six people.

Aren't they in the same group?

Now the situation is becoming confusing.

The crowd proceeded cautiously, and walked for another quarter of an hour, until they finally reached the end of the underground river.

The riverbank came to an abrupt end, and there was no road ahead, only a dark cave wall.

The end of this side is a little different from the upstream.

Upstream, there's a lake.

The underground river on this side flows directly into it.

It's like a sharp sword, stuck in a rock.

You Lanfeng lay down, sniffed again, and said, "They disappeared here." ”

It is surrounded by rocks and the top is low.

Chongning checked around, and there were no secret doors on the rocks everywhere.

Obviously, there is only one way, and that is this underground river.

However, the river downstream is turbulent and flows extremely fast.

Without good water, it definitely won't work.

Lu Panzhou groaned and said, "I, Lan Feng and Xuan Zhen, the three of us will go over and investigate." ”

"Just the three of you, just wait here."

Chongning's water nature is not very good, and he said: "It's okay, you guys be careful, go and go back quickly." ”

Duan Jingzhi said: "If there is any news, you will come back immediately." ”

Lu Fanzhou answered and said, "Xuanzhen, Xuanzhen!" ”

Hyun Zhen was a little absent-minded and didn't know what he was thinking.

Lu Panzhou called twice, but he didn't answer, "Xuan Zhen, are you in the water?" ”

Xuan Zhen was stunned for a moment and said, "Down, down." ”

Lu Panzhou frowned slightly, thought for a while, and said, "Xuan Zhen, don't go into the water first, take care of Chongning them." ”

At this time, Xuan Zhen's state had not yet recovered, and he was afraid of an accident.

Lu Fanzhou's mind is delicate and comprehensive.

Hyun Zhen answered, then sat down by the river and said no more.

Plop plop!

Lu Panzhou and You Lanfeng jumped into the underground river and went straight downstream!
