However, all this is based on the premise that Xu Feng himself is also an emperor-level strongman. With Xu Feng's current peak emperor-level strength, he is still powerless against an emperor-level strongman. No matter whether it is the killing curse or the decomposition technique, it cannot pose a fatal threat to the strongman who controls a small world!

By the Wangchuan River, Xu Feng was like an ordinary human soul, standing quietly by the river, as if waiting for something. Some weaker souls beside him, even if impacted by the breath of the Wangchuan River, could not regain their self-awareness, and still walked forward regardless, and were soon swept down to the bottom of the river by the river, slowly merging with the river water. Xu Feng could even feel that there were trillions of souls wailing and crying in the Wangchuan River, like a cage holding countless souls. Once imprisoned in it, no matter how hard they struggled, it would be useless, and they could only let the Wangchuan River continue to surge, not knowing where they would be washed to. After an unknown amount of time, more and more souls stayed by the river bank. These souls, impacted by the breath of the river, had completely regained their self-awareness, and their eyes became smart, but they seemed to have known that they were dead, and were now waiting by the Wangchuan River to cross the river. They did not suffer from emotional breakdown, but some women were sobbing in a low voice, with fear on their faces.

"When will the ferryman come? There are already thousands of souls gathered on the river bank, and at least three times as many have entered the river as on the bank..." Xu Feng thought to himself, "Could it be that the Netherworld relies on this method to repeatedly select souls that can enter reincarnation?"

Xu Feng frowned, and had been waiting for a long time, becoming somewhat impatient, but the souls beside him were all standing quietly, without any impatience, and their faces were full of numbness;

The sky here is always filled with dark clouds and fog, and it is dark all around, as if it is the eve of night, and everything is hazy.

As time passed, the originally empty river bank was suddenly filled with countless faint gray air currents. These air currents kept surrounding those unconscious souls that were like zombies, circling around their bodies.

Seeing this strange phenomenon, everyone's heart trembled. Their originally numb souls were now filled with fear on their faces. They seemed to be very afraid of these gray air currents and stayed away from them.

These gray air currents seemed to have self-awareness. When they saw everyone fleeing, they did not chase after them, but only approached those souls that had not regained self-awareness and were still walking towards the Forgetful River. The gray air currents swirled around these souls, but the souls were unaware and only knew to move forward. Soon, the breath of the souls became weaker and weaker, but the air currents continued to grow stronger, as if devouring the souls bit by bit. Some weaker souls became nothingness and disappeared before they even got close to the Forgetful River. Although some strong souls were slowly devoured by the gray air currents, they were still able to hold on to the Forgetful River. For those souls that stepped into the Forgetful River, the gray air currents immediately left and turned to the next soul.

Xu Feng's heart moved. If these gray air currents were allowed to devour the transparent souls in this way, they would eventually grow stronger. When they became strong enough, they would definitely attack those souls that had regained self-awareness.

Thinking of this, Xu Feng pointed at a gray airflow, and a red beam of light shot out with a "whoosh".

The finger force swept across the airflow, breaking it in one stroke. The airflow actually made a sharp "squeaking" sound, and everyone's face changed when they heard it.

"What the hell is this thing!" Xu Feng thought to himself. A crisp sound of falling was heard , and a crystal the size of a fingernail appeared where the gray airflow dissipated. Although the crystal was small in size, it was as heavy as a thousand pounds. It fell to the ground with a sound of metal colliding. Xu Feng narrowed his eyes and held the crystal in his hand with a casual move. "It is a low-grade soul crystal. There is a certain chance that it will drop after the Nether Beast is annihilated. The cultivator can use it to enhance spiritual power and expand the purple mansion sea of ​​consciousness. However, after use, it will be eroded by the Netherworld's breath, causing the mind to be dusty. Undead creatures are immune to the dusty mind!"

Xu Feng frowned slightly. Treasures that can enhance spiritual power and expand the Purple Mansion's Sea of ​​Consciousness are all extremely precious spiritual treasures. They are rare even in the upper realm. Even though this soul crystal has some negative effects, many cultivators will use it without hesitation!

"This should be used specifically for undead creatures!" Xu Feng shook his head, put the low-grade soul crystal into the space package, and looked around;

At this time, the gray aura on the bank of the Wangchuan River was getting more and more, and the speed of devouring souls was also getting faster and faster. Many souls had already fled in all directions out of fear, and some even rushed directly into the gray fog that filled the surroundings in a panic. After a while, a sharp scream was heard...

Several gray air currents seemed to be targeting Xu Feng, the only "soul" standing still, and swam towards him quickly;

A mocking smile appeared on Xu Feng's face. With a thought, a dense mass of purple-black talismans suddenly appeared around him...

Boom, boom, boom~ One talisman after another turned into lightning and struck towards the approaching gray airflow like a thunder tribulation. These gray airflows could not withstand the damage of the Purple Sky Divine Thunder at all. They let out a shrill scream and dispersed. For a moment, all the gray airflows around seemed to think that Xu Feng was not easy to mess with, and they all moved away from Xu Feng. After a while, a large area around Xu Feng was vacant, as if he had been forgotten.

The gray airflow devoured the transparent soul faster and faster, and became more and more dense, the color changed from light to dark, and the volume also increased a lot. In the end, it turned into a gray giant python, wandering freely in the air.

Not long after, these gray air currents seemed to lose interest in the zombie-like souls and stopped devouring those souls. Instead, they began to entangle with each other.

Either two or three, they merged with each other, and the air currents that were originally of different colors gradually began to turn into one color.

At first Xu Feng thought they were merging with each other, but after careful observation, he found that these gray air currents entangled with each other were actually fighting and devouring each other. The loser lost everything and the winner gained everything. After swallowing an air current, the winning air current would become thicker and longer, and the color would become richer. Then it would pounce on the next air current for the next round of devouring.

The originally countless dense gray air currents, after devouring each other, formed several black air currents as thick as buckets.

These black air currents continued to fight each other, and eventually formed nine black air currents.

There is no wrong version in the 1619 book forum!

These black air currents seemed to be over a hundred meters long, emitting a strange light on the surface, as if nine giant pythons were swimming in the air.

The nine black tornadoes no longer continued to devour, but instead coiled up into a ball like giant pythons, emitting a black Netherworld light all over their bodies. They kept swallowing and exhaling like they were breathing, and it looked like they were gestating something.
