The ghost country in the south, the big and small Yin Mountain.

These are two parallel mountains running east-west, trillions of miles from west to east, roughly separated by millions of miles, like two towering walls, sandwiching a long strip of plain.

The Yin Wind Field is the name of the plain between the big and small Yin Mountains.

Here, there are countless ghost caves, hiding countless ghosts, and there are countless ghosts and ghosts.

There is also an old ghost who has already fallen for I don't know how many years, and can be called the founding ancestor of the ghost country, using his great magical powers, and moved countless extremely yin veins from the ground to connect the yin wind field.

The day is covered with dark clouds, there is no daylight, and the ground is full of yin like a tide, rushing with the mighty wind in all directions. There are also vicious prohibitions arranged by generations of ghosts, and in previous years, as long as a dry skeleton was thrown in the Yin Wind Wilderness for a few years, an extremely powerful ghost could be born.

This is the foundation of the ghost kingdom and the lair of the ghost venerables.

Including the Relic Ghost Venerable under Wu Tie's command, the Three Huangquan Venerables, and the Five Great Ghost Venerables who had just taken refuge, their lairs were all in the Yin Wind Field.

At this moment, in the Yin Wind Field, countless ghosts gathered.

The Nine Great Ghost Venerables erected the spirit flag, and in the huge ghost country, countless ghosts and ghosts heard the wind and moved, and they gathered towards the Yin Wind Field.

Wu Tie, Yin Yang Dao people, Canghai Dao people, and Five Elements Dao people are lined up in a line suspended in the void, regardless of the deity clone, and at the same time exert the Buddha's super Zen light, like four small suns illuminating most of the Yin Wind Field.

As soon as the countless summoned ghosts touched the golden light, they let out a long howl that they didn't know whether it was sadness or joy, and the ghost qi that had accumulated in their bodies for countless years was washed clean, and their bodies gradually became translucent, emitting a faint white light.

In this way, for half a month.

The spirit flags erected by the ghost venerables are of great use, but any ghost who senses the power of the spirit flag, no matter how low their strength is, the speed of their volley flight will soar out of thin air.

Ghost creatures are already flying extinct, and the speed of escape is their forte.

After receiving the blessing of the conjuring flag, the flight speed of these ghosts became faster and faster, and in just half a month, nearly seventy percent of the ghosts in the ghost country have been reincarnated by Wu Tie.

Behind Wu Tie's head, a round of merit golden light condensed into a substance was filled with golden light and purple qi, with a diameter of tens of thousands of zhang and a thickness of hundreds of zhang, like a heavy golden cake hanging behind Wu Tie's head, which looked particularly amazing.

After transforming so many ghosts, the power of merit obtained by Wu Tie is too huge, and in this round of merit golden light, there seems to be some strange changes brewing.

It's just that Wu Tie didn't care about these changes.

In the huge ghost country, only some scattered ghosts have not had time to come to accept the excess, and with the cooperation of several ghost venerables, this matter is about to be completed.

Leaving the Five Elements Dao people to continue to sit in the ghost country, using the Buddhist exercises to surpass the ghosts left in the ghost country, and leaving the five ghost venerables who had just taken refuge to assist, Wu Tie took the Canghai Dao people, the Yin Yang Dao people, the Red Lotus Demon Venerable, the Relic Demon Venerable, the Huangquan Three Venerables, the Six Desires Demon Venerable, etc., and went straight to the north at the fastest speed.

After the Black Flower Reincarnation Buddha and the Great Bronze Mirror were killed, the north side stopped for a while.

But as Wu Tie sucked all the Yin Yang Dao people away and went to the ghost country, the strange country in the north began to move again. When Wu Tie overtook those ghosts in the Yin Wind Field, emergency military information was constantly being sent from the north.

The climate is dry, the summer is very hot, and the winter is very cold in the northern Xinjiang of the Sui Dynasty, and the land is slightly barren compared to other places in the Sui Dynasty, but because of the unique advantages of the Sui Dynasty mainland, the land in the northern Xinjiang is still more than ten times better than the land of the Three Kingdoms Continent.

However, overnight, the land in northern Xinjiang began to become inexplicably desertified.

Great rivers and rivers disappeared out of thin air, mountains and peaks turned into sand dunes, patches of forests and grasslands were swallowed up by sand grains, and the soil that used to be able to pinch out oil and water became extremely barren in just a few days, and then quickly turned into a neighbor.

With desertification, many plants endemic to desert areas, such as giant cactus pillars, have grown.

These giant immortal pillars, which are hundreds of feet high, are pale blood-colored, and the lines of human facial features are faintly born on their thick bodies.

At night, these giant immortal pillars let out a subtle crying sound that made people shudder to hear.

The desert slowly advanced from north to south, and when Wu Tie was about to rush back to the north from the southern ghost country, there were already three military cities that could not resist the erosion of the desert, and all the soldiers and civilians were withdrawn, and all the buildings in the entire military city, and all the fields, fishing grounds, pastures, forest farms, etc., outside the military city, were swallowed clean by the yellow sand flying all over the sky.

The elders of the Wu clan sitting in the north, along with Li Xuangui and Yuan Qilin, two masters who were proficient in feng shui and earthly veins, tried to survey the desert and those strange giant immortal pillars.

As a result, the desert was restless, and it almost pitted a group of Wu clan elders into it.

Li Xuangui and Yuan Qilin were the worst, and they were not good at frontal combat, so they almost failed to escape from the desert.

Although they were rescued by the ancestors of the witch clan such as the witch prison, Li Xuangui and Yuan Qilin were still pierced like a sieve by the long thorns spewed out by the giant immortal pillar, and they were even hit by the strange poison that came with those long thorns, although they were treated in time, they were still lying in bed unconscious.

Therefore, after receiving the information, Wu Tie immediately returned to the north with a large group of men.

He didn't even bother to go up to Suidu to see the recent situation of Feng Cao, and he didn't even care about punishing the wanton army under the command of the Nine Kings who were in turmoil, and he came directly to the largest military city in the north, 'Dingbei City'.

To the north of Dingbei City, there are dozens of small military cities that exist as outposts.

The desert that suddenly appeared had not yet been able to engulf these small military cities, and there were still tens of thousands of miles away from Dingbei City.

But the scorching hot wind blew from the north, and the smog covered the sky, and as far as the eye could see, there was a foggy, yellow and dreary patch in all directions. Fine dust was constantly falling from the air, spreading evenly on everything.

The buildings, flowers, cars, and horses in Dingbei City, as well as the pedestrians on the road, are all covered with a layer of yellow dust, and the gray face is not sad.

What's even more surprising and inexplicable is that that kind of giant immortal pillar has occasionally appeared in Dingbei City.

In just a few days, there were more than 30 giant immortal pillars.

There were no casualties among the soldiers in Dingbei City for the time being, but more than a hundred ordinary people in Dingbei City had been killed and injured by the long thorns spewing out of the giant immortal pillar.

Xiahou Ba, one of the several great commanders of the Sui Dynasty sitting in the north, stood beside Wu Tie and seriously told Wu Tie everything that had happened these days.
