Next to the main pipeline, there is another small water outlet, forming a very peculiar root waterfall, like an old tree growing on the edge of the cliff, countless roots stretch out from the cliff cracks, hanging in the air.

The headlamp shines past, and the white flowers are as thin as silver threads, not like water, but more like quicksand.

For thousands of years, the pouring torrent washed a large pit in front of the pipe, and then the water slowly gathered and flowed into the depths of darkness.

Staring at the surface of the river, the light could not shine into the river, only to see the satin-like water surface slightly undulating, transverse waves of thousands of hills, as if solidified into ink-colored glass.

The black river and the black rock are connected together, and it seems to be infinitely far-reaching.

Everything is like a strange dream, a miracle forged in the darkness of the underground world.

It is the handiwork of nature, like a tireless coal digger, who has transformed the underground world into a majestic and tortuous underground palace with a time limit of 100 million years, and then carefully covers it with darkness and carefully cares for it with the water of life so that no one can discover it.

When you stand at the source of this underground river and look up, you will think that there is a mountain overhead, and if you look into the distance, it is endless darkness, and how many secrets are hidden in the darkness, leaving only people to imagine and guess.

"It's cold"! The old servant beside the old man, Chu Jiu, couldn't help but shake his body.

The air here is cold, but it is refreshing, like the first snow of winter.

But the old servant is old after all, he is not like Sun Miao, who is entering the Tao as a doctor and knows some ways of conditioning, and he is just a half-hung doctor who serves the master.

"Hold my hand". Master Ulla is in a good mood, and he can be regarded as giving a big face.

Chu Jiu felt a trace of warmth coming from his hand for a while, and went straight into the dantian.

"Let's go"! Zorey gave the order.

"Brother, what did you say"? The sound of water pipes draining was roaring in my ears, and it was impossible to hear it clearly.

Zhuo Lei could only say it out loud once.

This time everyone nodded.

After walking about 500 steps, the sound of the water at the entrance gradually became quieter, replaced by some cold water dripping down the top wall into the river, making a crisp "ticking" sound, but the darkness was still there, and the road ahead seemed endless.

It was clear that it was a horn-shaped tunnel, and the deeper they went, the bigger the inside of the tunnel they saw.

For the wider and wider underground river, the road ahead seems to be brighter, the original black as ink underground river turned amethyst color under the strong light, the four walls are smooth rocks, like a miniature version of the stone forest layered on top of each other, thousands of ravines and folds.

Suddenly, everyone stopped, it turned out to be a small waterfall, the light moved down, in the place of the impact of the waterfall, the riverbed was sunken, forming a smooth porcelain basin, more like a blooming lotus flower, there were countless goose egg-sized stone balls in the pot, smooth and clean like pearls, rolling under the impact of the water.

In the distance, the riverbed was as flat as marble, and the amethyst refracted the light and outlined small golden snakes on the riverbed, writhing endlessly; The sparkling waves are projected onto the cliff wall overhead, where a few stalactites still hang down like vines, as if corresponding to the stone forest at the bottom of the water.

Roll under the waterfall and land safely, and continue to move forward, with a view of the strange lava forest.

On the way, they found more than a dozen small tributaries, and the black hole didn't know where it was going, but according to Zhuo Lei, this kind of small tributary that couldn't even be squeezed through by people was definitely not the route on the map, so they kept moving along the big dark river.

Gradually, in this quiet underground world, many aquatic creatures appeared one after another, and the agile newt quickly flashed into the small cave with slight fluctuations.

Blind shrimp and blind crabs, leisurely waving their claws at the bottom of the water, picking up sediment, the crowd passed, the slightest disturbance, they immediately turned into the underwater cavern, disappeared.

"If there is a boat, we will be in it sooner or later." Huzi's words were recognized by everyone.

The river in front of them gradually narrowed and steepened, and the rock walls on both sides seemed to be about to merge, and the water was as fast as the Yajiang River in the outer realm, and they became more and more unable to control themselves.

"Stick your feet in front of you and go with the waves". Zhuo Lei is more sensible, and if his head touches the reef in front of him, the person may be gone.

"I see there's a platform up ahead, and we can adjust it a little bit there." Forward Yinghuzi quickly reported the situation ahead.

Finally climbed a protruding rock in front of me, everyone was gasping, fortunately this underground cave is not as cold as imagined, on the contrary, there is a warm feeling, not to mention diving, even if it is lying in the water for a long time, it must freeze to death.

"If you continue to play like this, our master and servant will have to be played to death by you." Old man Sun was really angry, he didn't expect to suffer such a hardship when he was old.

If it weren't for the fact that he had cultivated some qi cultivation methods, I am afraid that he would have died many times.

"You think we want to"! Mu Ge glared at him and said coldly, "If you don't want to play, you two can go back."

He was sure that Sun Miaozheng and the two would not leave, after all, they wanted to go back here, and with their strength, they would die without life.

"You ......" Chu Jiu's hateful gaze can't change his fate after all.

"Okay, now it's all grasshoppers in the same boat, if you can find Shambhala, the holy medicine inside is all yours." Zhuo Lei interrupted the two sides at the right time, and the quarrel could not solve anything.

If it weren't for the fact that the old man's medical skills were too high, with the burden on his two roads, I was afraid that they would be the first to die.

"Can you swim in the river for a few days, a day, two days, a month, two months"? These people are really a bunch of crazy people, the old man really wants to wake them up, although there are underground reefs and protruding rocks to rest for a short time, but they can be soaked in water all day, there is no end to the road, and everyone will have despair.

"Amitabha, donor, the Buddhists say that since the status quo cannot be changed, then you can only endure it silently." The old man helped the monk find the key, and he came forward to defend him for a while, if he didn't provoke Zhuo Lei and the others, he would really kill people.

"Don't make any noise, it's not that there are no boats in the dark river, but they haven't arrived at the location yet, as far as I know, Xidi's former troops have experienced a lot of boats that have flipped in it, as long as the tide recedes, it can still be used, otherwise I won't come in." I see, this Zhuo Lei is really calm.

Sure enough, he is a person with the style of a general.

Lao Suo also sighed when he heard this, otherwise he really didn't want to leave.

The crowd rested for a while, and their spirits were high, and if they found the boat, they would be much more relaxed.

Moving on, the searchlight went with the trend, and I saw two black holes on the left, one to the left, and the other to the left, parallel to the cliff; In the place where the light does not shine, there seems to be a hole, and the shadow of the cliff wall is reflected on the wall, and different junction lines appear.

"It's a fork in the road!" Huzi exclaimed.

"Left"!

As Zhuo Lei said, after advancing less than fifty meters, there was a sudden big turn of nearly 100 degrees, and after turning the corner, they began to walk in the direction of the exit of the cave, and this section of the river was also surprisingly smooth, there were no rapids, but the slope was slightly steep.

It's a little harder, but it's better to be safe.

I don't know how long it has been, anyway, it's hard to have day and night here, so I'm tired and find a platform to rest for a while and move on.

Suddenly, Yushan stepped forward and grabbed the corner of Zhuo Lei's clothes and pointed at him.

But in the dark light, he couldn't see it clearly.

Mug stood next to him and shone his searchlight into the air.

Unexpectedly, under the illumination of the lights, several people saw an extremely surprising scene - a boat!

A large ship about two meters wide but more than a dozen meters long hung upside down above them, and it hung silently and serenely in the air, as if waiting for the next passenger forever.

Under the light, they first saw the inside of the ship, like a disembowelmented snake.

The hull was made of unknown materials, but it was thick and tough.

The hull of the ship is round like a barrel, and the keel and ribs are in the shape of "Feng" to stretch the whole boat.

I don't know if it's the bow or the stern of the boat, like the two ends of the shuttle shrinking abruptly, slightly rolled up in a semi-arc.

The keel and the tip of the ship are intact together to form a bulging bulge, for which the purpose is unknown.

In addition, there is no decoration or modeling, and it is as simple as a canoe. As the light moved, everyone saw the whole ship, which was a shuttle-shaped canoe, but with an "S" twist in the middle.

The tips of the two ends are raised high, one high and the other low, and even the lower end is higher than the arc of the Venetian dinghy.

The top is a bulge connected to the keel, which looks a bit like a huge living snake.

Although the shape was strange, they had never seen such a boat, but from the first time this thing appeared in everyone's field of vision, they almost didn't think about it and decided that this was a boat, it must be a boat!

The serpentine ship was firmly stuck between several stout stalactite pillars, the slightly curved stone pillars were like the claws of a giant beast, holding the ship firmly and hanging in the air, in the incomparable darkness, no one could notice its existence without paying special attention.

Mu Ge frowned and asked suspiciously, "Could it be that the water level of the Dark River has ever risen to that height?" ”

Then they - it seems that the road ahead is still life and death.

After a moment, he stared at the strange ships and muttered, "Somewhat like ancient keel boats".

When Huzi heard this, his voice widened and he asked, "Brother Muge, what is a keel boat."

Before Muge answered, Zhuo Lei paused for a while and said: "That is the most commonly used water transportation for Tibetans in ancient times.

In this boat, the keel is set on the inside, and the cowhide is prepared on the outside, and the bottom of the boat is usually made of a complete piece of skin, and the hull is spliced with four to five pieces of skin.

After entering the water, the cowhide is blistered and soft, just like the cow tendon, it is extremely tough and elastic, and it can be avoided with a flick of the violent impact.
