After walking along the river for a day, Xue Wenrui did not see the end of the river, nor did he find a way to cross the river. It's just that there is no need to worry about those warning demon beasts by this river, the spiritual power here is also like poison to them, and this poison can't resist even if there is a purple-throated pill, how dare they come.

In the early morning of the second day, he suddenly had a happy face and galloped forward.

After half a cup of tea, Xue Wenrui stood still and looked at the river with an excited expression.

The river here is still rich in spiritual power, as if it is made of spiritual power, and it is no different from other places. The only difference is that above the river, there is a row of black rocks protruding from the water.

The stones were square, about the same size, and no more than two feet apart from each other, and the stones stretched forward into the thick fog, like stepping stones in the stream of Mosang Town. Xue Wenrui could be sure that the direction that this row of stones led to must be the opposite bank of the river.

"Hahahaha, there is actually a road!" Xue Wenrui was overjoyed, it turned out that this river was not a Jedi, but a glimmer of life. It's just that in order to find this vitality, you must be able to resist the toxicity of the purple-throated miasma. Just like that Li Feiyan, they couldn't resist the poison of the purple-throated miasma for a long time, and they couldn't walk around the "River of Spiritual Power" at will like him, so naturally it was impossible to find this place.

Despite his excitement, Xue Wenrui calmed himself down and didn't rush forward immediately.

He summoned the Terran undead and sent them to the test.

The undead of the human race received Xue Wenrui's thoughts, and trotted all the way, jumping towards the first stone. This undead spirit has the cultivation of the early stage of foundation building, although the body cannot be compared with the body refining cultivator, but the distance of less than two zhang is not the same, and there is no problem in jumping over.

The Terran undead leaped lightly and landed on top of the first stone. The stone was solid, not shaking at all, and nothing strange happened.

Xue Wenrui showed joy, it seems that this is indeed a passage to the interior of the Dark Demon Valley. He gave the order for the Terran undead to move on, waiting for him on the other side.

The Terran undead continued to leap, but just as his feet were about to land on the second stone, the stone suddenly shook, and then the top of the stone fell, and the whole stone suddenly turned into a black hole. A strong suction force suddenly struck, and a vortex of gas several feet was formed above, and the undead of the human race could not resist at all, so they were sucked into the stone cave.

The undead of the human race disappeared in a blink of an eye, and Xue Wenrui's big open mouth did not close for a long time. And the surface of the second stone gradually returned to its original state, and the cave disappeared, and the whole stone was exactly the same as the stepping stone that was common in the stream.

"How can this be? Could it be that the second stone has a mechanism?" Xue Wenrui muttered to himself, looking at the row of stones in a daze.

He picked up a stone and threw it at the second stone as best he could, but as soon as the stone entered the river, it always fell down a mile away, and the second stone could not even reach the first.

Subsequently, Xue Wenrui changed to various stones of different sizes, wood, bamboo, etc., but the result was the same.

An hour passed, and Xue Wenrui's "Demon Spirit Summoning Technique" was finally able to be used again, and he once again summoned the undead of the human race. Since the other materials had no effect, Xue Wenrui calmed down instead, preparing to use the Terran undead to slowly test it.

This time, it wasn't until the Terran undead jumped to the third stone that the mutation happened. In the third stone, a crimson spirit snake suddenly burst out, wrapped around the feet of the human undead at a lightning speed, and threw it into the "river of spiritual power". The undead of the human race who built the foundation realm was like a straw, fluttering lightly and unable to resist at all, and was thrown into the river.

The undead of the human race fell into the river, and the bones of the power of divine thoughts actually began to grow a trace of flesh and blood, but with a cup of tea, the bones were restored to a monk, who was made into a magic pattern by Xue Wenrui when the Southern Regions met the alliance.

It's just that although this person is full of vitality, he has no consciousness at all, and can only float quietly on the surface of the river, motionless. Then, his body began to grow smaller, from a prime of life to a youth, a teenager, a child, and finally a baby, gradually sinking into the bottom of the river and disappearing.

At the moment when the baby disappeared, a piercing scream suddenly came out, which frightened Xue Wenrui into losing his mind, thinking that he was almost about to escape underground when he was discovered by the warning demon beast.

He settled down, wiped the cold sweat on his forehead, and had to say that this river was too weird, if it weren't for the fact that he was bound to win the Xuanjin Mountain, he really didn't want to provoke this inexplicable existence.

Next, Xue Wenrui tried various methods again, while waiting for the "Demon Spirit Summoning Technique" to be able to be used again.

When the third Terran undead stepped on the stone, a different scene appeared.

As soon as he stepped on the first stone, a hole the size of an arm suddenly appeared, and then a thick black smoke burst out of the hole, spraying at the Terran undead.

Under Xue Wenrui's thoughts, the undead of the human race did not dodge, and still stepped on the stone, allowing the black smoke to fall on his body.

To Xue Wenrui's delight, the smoke did not cause any harm to the undead of the human race, but only made him black, as if he had just come out of a coal mine.

The Terran undead continued to beat on the second stone, and the stone still emitted a cloud of black smoke, which did not cause him any harm, but made him darker.

In this way, the undead of the human race jumped to the other side after a stone, one stone after another, and after a meal. By exchanging visions with the undead of the Terran race, Xue Wenrui found that the situation on the other side was similar to that on this side, and there was no danger. And this river is indeed extremely wide, about 300 zhang.

The Terran undead circled around the other side for a while, and found nothing else, so they walked back under Xue Wenrui's instructions. But when he stepped on the second stone, there was another scene when the first undead crossed the river: the second stone shook for a while, and the stone surface fell, turning into a black hole, and a strong suction force was transmitted, forming a gas vortex, sucking the Terran undead into the stone cave.

In this way, Xue Wenrui used the undead of the human race to trial and error. After a day, the pattern of these stepping stones was clearly understood.

There are only three variations of these stones, and these three variations occur in turn. The first is that the stone face falls, forming an air vortex, sucking the river crossers above the stone into it, this suction is extremely powerful, and it is difficult to resist without a sixth-level cultivation.

The second is to come out of the rocks with a snake that catches the crosser and throws him into the river. Although this snake is flesh and blood, it does not feel like a real snake. The strength of the snake is also extraordinary, and Xue Wenrui thinks that it is difficult for him to resist at all.

The third is to spew out a black smoke, this black smoke is estimated to be poisonous, but it cannot damage the undead of the human race who have no life at all. In order to test the toxicity of the black smoke, Xue Wenrui also captured a demon beast, stunned it, and tied it to the human undead to cross the river together. As a result, the late-stage third-stage demon beast completely turned into a puddle of sewage when it stepped on the first stone, which showed the strong toxicity of the black smoke.

The stones that are activated in the three situations are also different. The first starts when you step on the second stone, the second starts when you step on the third stone, and the third starts when you step on the first stone.
