He dived into the pond just now, the deepest part of the pond was about four or five meters, the depth was not as calm as the surface of the pond, the water was very turbulent, Tang Chen was caught off guard, and was almost washed away by the current. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

He successfully found the water outlet, which was not far from the stone bridge, close to the junction of the kitchen and the stone bridge. There is a hole with a diameter of less than one meter at the bottom of the pool, and the entrance of the hole is dark and deep, like the throat of a monster, and a large amount of pool water is sucked into it and disappears into the darkness in an instant.

Breathing a little evenly, Tang Chen dived into the bottom of the pool again, carefully exploring along the pool wall, and the location of the inlet was quickly determined. Tang Chen didn't stop, he continued to search around the pool wall, until he confirmed that there was only one outlet and inlet in the pool, then he climbed up and lay down on the stone bridge to rest.

This is supposed to be a dark river flowing through the belly of the mountain, and it is very likely that the dark river will eventually connect to the rivers or lakes outside, but it is impossible to estimate how many places it will eventually flow through to join the rivers and lakes, depending on the flow route of the dark river. The best result is a flat river, but, if you're unlucky, it's not surprising to make a bend in the belly of the mountain.

One thing is for sure: walking down the dark river, there is a lot of hope for the valley!

After experiencing the blows of the Heavenly Ladder Project and the Broken Teleportation Array one after another, finding a way out of the valley from the waterway became another hope for Tang Chen to get out of trouble. Once a thought comes to mind, it can no longer be erased.

Tang Chen is full of fighting spirit and is burning!

Tang Chen picked up a burnt torch and used charcoal from memory to draw the nearby terrain on the stone bridge.

In order to catch the grass family rabbit, he had studied the terrain of the Dadong Mountain Range, just to find a safe route to the grass family peak, so as not to be killed by the spirit beast halfway through, and the jade slip with the topographic map of the Dadong Mountain Range is still in his Qiankun bag. But the accuracy of that jade is not too high, although the large terrain is basically not wrong, and the details can only be added by Tang Chen himself. Fortunately, he had the experience of squatting on the peak, and for more than ten days, Tang Chen could only lie in a hidden place most of the time, looking at the scenery near and far under the peak to kill time.

He finally restored the nearby terrain roughly.

The cave is deep in the belly of the mountain, and the road is twists and turns, Tang Chen can't accurately locate the location of the cave, he can only use the Caoke Peak as a reference point. Since I don't know the general trend of the dark river, it seems to be westward now, and after a few turns in the belly of the mountain, it is likely to finally emerge from the east, and it is very unreliable to speculate in which direction the dark river will connect with the aboveground water system from the current flow direction, and Tang Chen does not do that useless work.

With Caoke Peak as the center, there are two rivers and five lakes within a radius of 10 kilometers.

The nearest river is only 3,000 meters from the Grass Peak, and the other is about 5,000 meters. The lakes are more widely distributed, the nearest one is under the Caoke Peak, the other four lakes are all five kilometers away, and the farthest one is ten kilometers away, almost beyond the target range set by Tang Chen.

There are many rivers and lakes nearby, and the possibility of getting out of trouble from the dark river has undoubtedly increased, and the most ideal result is that the dark river leads directly to the lake under the Caoke Peak, followed by the river three thousand meters away, Tang Chen is eager to try.

However, there are also great risks associated with walking in dark waterways, such as breathing problems, injuries from hitting rocks pushed by currents, whether you will encounter underground waterfalls, and whether there are any hostile creatures in the river...... Any of these risks can be fatal, some can be solved, and some can only be bet on luck.

Tang Chen quickly made a decision: take a gamble!

There was no hope of repairing the teleportation array, and the Ladder Path did not have enough resources to support it, so it was impossible to succeed, and the danger of the Dark River was nothing compared to the risk of making a hole in the cliff with a wooden stick. Of course, he could also do nothing and stay in the valley until the end of his life, but as soon as this choice appeared in his mind, he was ruthlessly ruled out by Tang Chen.

Brother is young, and An can live to the end of his life!

Brother has to eat all the world's food!

Brother hasn't dated yet......

Tang Chen began to refine his plan to minimize the risk as much as possible.

He took out a bundle of rattan rope and tied one end to the stone table, the other still tied around his waist. Turned out a few gourds for holding water, poured out the water inside, tightened the bottle mouth, and put them back into the Qiankun bag one by one. After doing all this, Tang Chen jumped into the pool and dived to the water outlet.

He didn't hesitate to dive in.

After entering the water outlet, Tang Chen felt as if he had been vigorously pushed from behind, and the speed of the water suddenly accelerated, pushing him forward quickly, until a strong force came from his waist. The vine rope had been put to an end, and there was still darkness in front of Tang Chen.

"Damn!

Tang Chen cursed in his heart, and immediately turned around and retreated the way he came, which was tantamount to fighting against the turbulent water. Tang Chen grabbed the rattan rope with both hands, pedaled the bottom of the dark river, and went up the current step by step, and it took a lot of effort to get rid of the suction of the water outlet and return to the cave.

After resting for a while, and after recovering his strength, Tang Chen took out all the remaining rattan ropes in the Qiankun bag, untied the rattan rope around his waist, and knotted it with another rope. He took a pearl of the night from the wall of the cave before returning to the pool, re-tying the rope back to his waist and jumping down again.

Underwater, Tang Chen took out the Night Pearl, the bright light emitted by the Night Pearl was as weak as a candle in the wind, which could only make Tang Chen barely see half a meter away, but it was better than having a black eye like before.

Entering the water outlet again, Tang Chen had become accustomed to the suction in the cave, his body curled up, his hands holding his head, his divine consciousness released, and let the water flow carry him into the depths of darkness. When the rattan rope was tightened again, Tang Chen repeated his old trick, almost lying on the bottom of the water, using his hands and feet at the same time, resisting the impact of the water and walking back. When he walked about three meters away, he suddenly stopped and stood up cautiously.

"Boom!"

His head hit the stone and made a soft sound, but Tang Chen laughed happily: "Huh, there is nothing wrong with the divine sense, there is indeed a piece here that has not been flooded by water, and it can be used as a ventilation point." ”

Qi refining cultivators are still unable to use internal breath, and they usually have nothing, but the underwater environment is greatly affected. With the ventilation point, Tang Chen's stay in the dark river could be extended.

Tang Chen already had a preliminary plan, he wanted to explore the dark river as much as possible, and if conditions permitted, he would tie a rattan rope to the ventilation point, and the length of the rattan rope would depend on the distance between the two ventilation points. Tang Chen hopes to divide the dark river into small sections with ventilation points like a relay, and fight steadily and steadily, step by step, until he leaves the mountainside, or the relay cannot continue!

It's not easy, but it can certainly reduce the risk.

Compared with the ladder plan, the dark river channel is much more operable.

Tang Chen quickly dived back to the bottom.

The first ventilation point is only two meters square, and it is a confined space isolated by water and rocks, and it is difficult to replenish the oxygen in it after it is consumed. Tang Chen didn't want to waste precious air in vain, although his body's demand for oxygen increased when he went against the current, he had another way.

Taking out a gourd and unscrewing the bottle, Tang Chen quickly stuffed the bottle mouth into his mouth.

"Coo", an extra string of bubbles in the dark river.
