This trace of spatial power is okay to collect things, but it is difficult to use the spatial power in the space gourd to carry out spatial teleportation just like in the outside world.

Yun Lei entered this space, but saw that this space was indeed as the thoughtless ghost monk said, the yin aura was rich and sufficient. If the concentration of Yin Aura in ordinary places outside is one, then the concentration of Yin Aura in some cemeteries and morgues is three to five, and where the ghost city of Fengdu is located, the concentration of Yin Aura is often maintained at about twenty or thirty.

And the concentration of Yin Spiritual Qi in this space is three to five hundred times that of ordinary places in the outside world! It is even twenty or thirty times that of the ghost city of Fengdu!

In the breath of cloud and thunder, they can inhale the yin spiritual qi into their hearts. Sure enough, compared with the Fengdu ghost town in the outside world, this place is more like the legendary underworld of the world.

In this heaven and earth with a rich yin aura, almost all existence is contaminated by the yin aura, not only the clouds in the sky are gloomy and deep gray, but even the air is a faint gray. The earth was gray, dark and black. And the grass and trees that grow on the earth are either gray, white, or black.

It's like an image on a black-and-white TV.

The only colors are the flowers and fruits present in these plants, many of which shimmer with fluorescence. These fluorescents are very extreme in color, either pure deep purple or rich blue. And the faint green. Little by little, like a ghost fire.

Yun Lei distinguished the strange plants and trees that grew on this ground, contaminated by the Yin Aura, or because they adapted to the Yin Aura, they could survive in this world, and muttered: "Yin Spirit Grass, Soul Attracting Flower, Flower on the Other Side, Wutong Tree...... These legendary plants and trees do not grow in the outside world, but they are born here...... Could it be that this place is really a netherworld?"

The cloud and thunder broke into this space, and the place where they landed was an empty mountain field, among the grass and trees, and it was not a dead silence, silent. There was a large black bird with purple and green feathers on its wings. His eyes were red, and he was holding a head with two horns, all black, still struggling and writhing, and a strange snake spitting Yin Spiritual Qi flew past Yun Lei's side.

In the red eyes, the gaze that looked at Yun Lei was cold to the bone.

Yun Lei looked at this strange big bird, and suddenly his heart moved, and he whispered: "This is a ghost bird!"

Those who know more about this Chinese history book and harem battles know that in this ancient Chinese legend, there is a bird called the bird. The purple-green feathers of this bird are extremely beautiful, but they are very poisonous. Moreover, this poison can still be dissolved in wine. Therefore, in ancient China, there was the term "wine".

"The Classic of Mountains and Seas" says: There are birds in the mountain of Yaobi, like pheasants, and they are constantly eaten, and their names are birds. And Guo Pu commented on the cloud: "The duck is as big as an eagle, purple-green, with a long neck and a red beak, the head of a pit viper, the male name is lucky, and the female name is harmonious." ”

"The Ruling and Wild Birds" recorded: "Where the birds eat water, there are rhinoceros, and the rhinoceros does not wet its horns in its water, and the food will die." For the sake of the snake eater. "As for the way to make wine from the feathers of the bird, it is even simpler. "Jade Chapter" records: "Plover, poisonous bird eats snake, its feather painting wine, drink it and die." ”

That is to say, if the feather is used to whisk the best wine, the color and aroma of the wine will remain unchanged, and the poison will be exhausted.

"Dialectical Record: Poisoning Door": "People drink and swallow wine, their eyes are turned to the sky, their bodies are shivering, they don't know, they are like being drunk, they understand in their hearts but can't speak, and they die when their eyes are closed. Because its symptoms are like drunkenness, and the victim "understands in his heart but cannot speak", it has become a must-have product in palace fights and power struggles.

But Yun Lei understood that the poison in the feathers of this bird was not an ordinary poison. Its chemical composition does not extend beyond the periodic table. However, the poisonous snake that this bird preys on is a special snake that has always breathed in yin aura. Therefore, the toxins condensed between its feathers are also a special substance that combines Yin aura.

Yin aura is extremely poisonous to living beings, and the poison of this ghost is naturally a thing that seeks souls and lives for living beings. But for the Yin Spirit Ghost, the poison of this ghost is a rare elixir that can enhance cultivation. Because this bird also lives in places where the yin aura is relatively strong. It also has an inexplicable and inseparable relationship with ghosts. Therefore, it is called a ghost duck.

However, in the outside world, this bird has become extinct with the end of heaven and earth, and the aura has dissipated. Yun Lei is in the ghost city of Fengdu, and he has never seen this kind of bird. But I don't want to see one here. If the information given by the Nian Ghost Monk is correct, then the place where Yun Lei is located should have happened to fall into this world, and even Yin Spirit Ghost Creatures rarely set foot in the Yin Soul Mountain.

Otherwise, this kind of feather poison, a ghost bird that has a great tonic effect on the Yin Spirit Ghost Thing, has long been caught by the Yin Spirit Ghost Thing here.

Yun Lei was happy to see the hunt. He now has more than 20,000 Yin soldiers and ghosts under his command, and the poison of this ghost's feathers is just right for the Yin soldiers and ghosts under Yun Lei.

As soon as Yun Lei's mind moved, a trace of thunder and lightning spiritual power popped out.

According to the Thoughtless Ghost Monk, in this space, many of the laws of the outer world have been weakened. This heaven and earth is dominated by yin aura, not the masculinity of the outside world because of the sun. Therefore, in this piece of heaven and earth, even if ghosts wantonly devour the yin aura in heaven and earth, it is difficult to cause yin and yang conflicts and magnetic field changes like the outside world.

Therefore, it is rare to attract thunder.

Even if the ghosts in this space break through the bottleneck of cultivation and cross the tribulation, the heaven and earth thunder that they induce will be much weaker than the outside world. Therefore, the two of thoughtless and thoughtless can easily survive the Yuanying Thunder Tribulation without too much damage. This is a holy place for all yin spirits and ghosts.

And this cultivation holy place was also built by the ghosts and immortals who operated this space in ancient times, after thousands of years of painstaking management and continuous resource investment.

However, such a world has both advantages and disadvantages for yin spirits and ghosts. The advantage is that you can practice with peace of mind, but you don't need to worry about the sudden arrival of thunder. The disadvantage is that the yin spirits and ghosts in this world have not seen the world of the outside world, have not been rejected by the world of the outside world, and have not struggled to survive in the vast breath of the outside world.

Therefore, the perception of heaven and earth is much worse after all. Therefore, in this space, the number of ghosts in the foundation building period and the knot period is extremely large. However, the number of ghosts in the Yuan Infant Period is very small, and there is also an era in which the Yuan Infant Period has not existed for a long time, just like the outside world. And the Transformation Period has never been born in this world.
