The map was big enough that even if two people were supported, they would not sink into the mud, so Master Mingzong folded a long thick branch and used it as a pole to row the map deep into the swamp.

The swamp was full of silt, there was not a single intact soil, the silt had been deposited for I don't know how many years, and every time it was supported, it would stir up a sticky black paste, and a disgusting rancid smell would come to my nose.

Master Ming Zong shook the pole while looking up at the peaks on both sides. One peak is in the southwest and the other is in the northeast, which should be the Cangqiu and the Vast Hill on the map.

Both peaks are low, less than half as tall as nearby, and really look like mounds. Looking at it, Master Mingzong found a strange place, the top of the hill is relatively flat, and the side of the hill also has a large straight mountain wall.

He tilted his head and raised his hand to compare the appearance of the two hills, hey, the outline of the wall of Cangqiu and the top of the mountain is very similar, could it be that this was a mountain before?

A flash of inspiration flashed through his mind, yes, it was definitely the same mountain. The waterfall altar is vast, not referring to the cangqiu and the vast hill, but referring to the vast mountain.

Immediately, a new question arose in his mind, and the words of the stele had written that a building had been built to store the roulette wheel. However, the cultivators who draw the map have to check and correct the terrain on the map every year, if there is a building on the mountain, why no one finds it?

Unknowingly, Master Ming Zong and Zheng Qiu entered the center of the Rotten Water Swamp. It was still overgrown with weeds, but it was no longer silt, but a black, thick layer of stinking water.

Master Ming Zong lifted the pole and stirred the stinky water, his brows gradually furrowed. It's so strange that although it is a swamp, there are no water birds, snakes and insects, and the pole can't touch anything, not even the shells of crabs and shrimps.

In my impression, this situation was mentioned in the book "Riding on the Clouds", which is called the place of death.

According to the book, the dead places are mostly cliffs, swamps, deep valleys, and caves, and there are no living creatures in these places, and there are no signs of living creatures passing by.

There are two possibilities for the appearance of the dead place, one is that there are a large number of harmful things in the dead place, such as poisonous gas, poisonous water, and soil that will get sick after being contaminated. Another possibility is that there is a powerful force that drove the living creatures away from the place.

Master Mingzong squatted down, carefully dipped his fingers in some black water, put it to his nose and sniffed it. Stinky, except for the bad smell, the black water does not make people feel uncomfortable. Then the formation of this dead land, more likely, is the latter, with great power.

Paddled and rowed, Master Mingzong felt that the pole seemed to hit something, he stopped, and used the pole to probe to the position just now. Tuk-tuk, tuk-tuk, the head of the pole hits a hard object as if it were a stone.

He adjusted the distance and groped for the appearance of the stone, tuk-tuk, the stone seemed to be square, elongated, such a regular shape, absolutely artificial. Master Ming Zong drew the map a little farther away, then lowered the pole and raised his hands to urge his energy.

Boom, a wave of air smashed into the swamp, black water splashed, weeds rolled, and the swamp was suddenly separated. Boom, another wave of air smashed into the position just now, and the black water mixed with silt flew wildly to both sides.

Sure enough, in the mud of the swamp lay a stone bar two zhang long and half a zhang wide, and the stone bar was a little pitted, but Ming Zong could see at a glance that these potholes were traces of being chiseled with a manuscript.

The wave of qi he unleashed was very strong, not only exposing the stone bar, but also opening up the swamp in front of it. There was an identical stone bar in front of the stone bar, and Master Ming Zong had a guess in his heart, so he paddled forward a few zhang and used his skills to open the swamp again.

There are also stone bars in front of it! These stone bars are connected together, isn't it a staircase? The vast mountain is divided into two, and the rotten swamp in the middle is buried with steps, it will not be wrong, the building that hides the roulette must be here, but it is not on the surface, it is buried somewhere.

Boom, boom, boom, boom, Master Ming Zong kept agitating the air waves, opening up the swamp one zhang after another, and exploring along the stone steps. The air wave fell again, but the stone steps did not appear, strange, why not?

He looked up and found himself near the wall of the hills.

Looking at the bare mountain wall, a thought flashed through Master Mingzong's mind, he flew to the mountain wall, raised the pole and knocked on it. Tuk-tuk, tuk-tuk, there is no hollow sound, isn't it in it.

He retreated into the air, stirred up the air wave and smashed it into the mountain wall, boom, the rubble rolled down like raindrops, and a large crater appeared on the mountain wall, and the edge of the pit was full of cracks. Boom, Master Mingzong smashed the position of the big pit for the second time, the pit was deeper, and the cracks were bigger, but other than that, nothing changed.

It seemed that it was not in the mountain wall, Master Ming Zong turned his head and fell to the map.

Just as he turned his head, there was a cracking sound at the bottom of the mountain wall, and the stone face was scattered, revealing a black hole two feet wide. As soon as the black hole appeared, black water poured into the swamp, and it appeared to be a downward hole.

"Master, master!" Zheng Qiu's shout suddenly came from below.

Master Ming Zong lowered his head and found that the apprentice was waving to him anxiously, and the map under his feet was floating down the black water towards the entrance of the cave.

"Apprentice, don't panic!Master is here!" Master Mingzong kicked in the air, and the qi wave exploded in the air, and his body rushed towards Zheng Qiu like an arrow off the string.

When he stepped on the map, half of the map had already floated into the hole, he hurriedly squatted, and at the same time stretched out his hand to press Zheng Qiu down: "Get down!"

The map floats completely into the hole, and the light quickly dims.

"Master, it's good, it's so dark...... Zheng Qiu was very scared, and hugged Master Mingzong's arm tightly.

"Don't be afraid, apprentice, look, isn't this just bright. Master Mingzong spread out his palm and urged his energy to the palm of his hand, and the palm suddenly lit up with a pale yellow halo, illuminating the environment in the cave.

The cave went all the way down, turning around, Master Ming Zong and Zheng Qiu squatted on the map, sliding down the black water. From time to time, there were upside-down stalactites flying overhead, and Master Ming Zong shook his body to drive the map under his feet to change direction, avoiding the sharp stone tips of stalactites.

After a long time, the cave suddenly became open, and the map slid forward for more than ten feet, hitting a rock and stopping.

Master Ming Zong brightened the halo on his hand and stood up to observe his surroundings. It's a big cave, no, it should be said to be a cave.

The cave is flat, the shape is very irregular, the high place has three zhang, the low place squats and can't pass, the wide place does not shine brightly, and the narrow place has to pass sideways.

However, the cave is very beautiful, with long stalactites, stone flowers blooming on the stone walls, and clusters of crystals in the corners, shining like stars under the halo.

"Apprentice, hold on to my robe, and don't let go. Let's go in and see. Master Ming Zong stopped Zheng Qiu behind him and walked towards the depths with a halo of light.
