After listening to Yuwen Zhouyuan's words, Yuwen said to Wan obediently: "So Wan'er will call your brother presumptuously, Wan'er will meet my brother" Yuwen said that Yuwen bowed to Wan and Yuwen Zhouyuan three times.

Yuwen Zhouyuan hurriedly returned the salute and said: "Wan'er, have you been better injured since you inhaled the aroma of the phantom fruit?" There are a lot of yin souls in that earthly yin city, with your current true qi stage cultivation, it is very likely that you will be caught as a ghost slave by them, for your safety, I think it is necessary to improve your cultivation!"

"Improve my cultivation, brother, do you know the cultivation method of our ghost cultivation?" Yuwen asked Wan.

"Yes, brother, there are ghost cultivation exercises here. Saying that, Yuwen Zhouyuan found a ghost cultivation method from the Heavenly Book Exercises, and raised his hand to enter Yuwen Xiangwan's divine consciousness.

"Brother, this exercise is many times more advanced than my cultivation! It's really good!"

Yuwen Zhouyuan took out a forbidden talisman and released it, protecting Yuwen Xiangwan.

Yuwen Zhouyuan thought for a while, and then entered the Tianshu space with a move of his mind, and then found a vacant place, found some Yin attribute spirit stones in the spirit stone pile, and built a Yin Absolute Great Array.

After everything was arranged, Yuwen Zhouyuan walked out of the Heavenly Book Space, woke up Yuwen Xiang Wan and said, "You come with your brother, and your brother will give you an excellent place to cultivate!"

"Brother, what a rich yin spiritual power!" Yuwen Xiangwan said to Yuwen Zhouyuan in surprise after entering the big array.

"If the spiritual power is enough, cultivate well, and I will refine another furnace of Yin Ghost Xuandan for you!" Yuwen Zhou Yuan said.

Then Yuwen Zhouyuan returned to reality, and then entered the defensive array, raised his hand and took out a dark green glowing corpse king pill from the storage bag, which was obtained in the fog demon mountain when he was in the monk city, this kind of thing has been in the fire for thousands of years, and it has been kept in the storage bag since he got it, but I didn't expect it to finally be used today!

Then he took out a mushroom like a grimace - the mushroom, this mushroom is black-brown, exudes a thick fishy smell, the appearance is close to the grimace is the top grade, the more hideous the expression is, the more precious it is, this thing was auctioned at the auction in Black Rock City.

In the end, he took out a jade bottle, and when the jade bottle was opened, he saw a drop of red blood inside, and as soon as the blood was poured out, it kept jumping around in the palm of Yuwen Zhouyuan, full of spirituality, this turned out to be a drop of blood of a Yin Soul Beast.

These three kinds of spiritual objects are the materials for refining the Yin Ghost Xuandan, this Yin Ghost Xuandan is the elixir used in ghost cultivation, and it is also a rare pill, ordinary alchemists can't refine it at all, although Yuwen Zhouyuan has refined many pills, but this Yin Ghost Xuandan is the first time to refine, he knows that as long as a kind of rare pill is refined, his alchemy is an improvement.

Then Yuwen Zhouyuan took out the Dan furnace, released the Yin Yang Dan fire, and then opened the furnace with the Yin Fire, put the Corpse King Dan into the furnace, and the Yang Cremation Dan, only to see that the dark green Corpse King Dan was under the Yang Fire, and quickly turned into a viscous liquid that kept changing shape, and at the same time released bursts of foul odor until it was completely vaporized, and the green misty gas drifted uncertainly, but it was condensed but not dispersed, and it seemed like a cloud and mist in the Dan furnace.

Yuwen Zhouyuan saw that the time was ripe, raised his hand and threw the ghost-faced mushroom into the furnace, as if sensing the danger coming, the ghost-faced mushroom let out a terrible wail before entering the furnace, and his expression kept changing, more hideous and terrifying than before, to be precise, it was intimidation.

The ghost face mushroom dissolved little by little, and it didn't take much effort to turn into gas, but it still retained its hideous appearance, and it was not fused with the gas turned into the corpse king pill, Yuwen Zhouyuan sneered, and the yin and yang pill was cremated into an illusory Tai Chi pattern, and the yin and yang fish rotated at a rapid speed, and after burning for a while, the hideous grimace turned by the ghost face mushroom was shattered.

When the two gases are fused together, they turn into a liquid again.

Yuwen Zhouyuan warmed the medicinal liquid with the Yin Yang Pill Fire for three days and three nights, and then played the true human formula and threw the blood of the Yin Spirit Beast into it.

The liquid gas transformed by the Corpse King Pill and the Ghost Face Mushroom Because both of them are extremely yin attributes, when they encounter the Yin Spirit Beast, the drop containing positive blood immediately launched a siege, and now it is the key to the Hedan, Yuwen Zhouyuan carefully guided, and sweat drops the size of beans flowed from Junxiu's cheeks.

The drop of blood of the Yin Spirit Beast seemed to be twitching painfully, constantly changing shape, and the color changed from red to dark purple, until all the boiling liquid was absorbed, slowly turning into a green and faint color, decomposing into dozens of peanut sizes, but there was no fixed shape, as if it was a cluster of liquid droplets emitting mist, which was extremely weird.

At the same time, a fragrant fragrance of the elixir wafted throughout the entire defensive array, and because of the defensive array, there was no smell of the elixir in the room.

Yuwen Zhouyuan compared the record of the Yin Ghost Xuandan in the "Dan Dao Bible", it is not difficult for him to see that it is done, it turns out that the legendary Yin Ghost Xuandan is actually an invisible thing, and he was overjoyed to accept the Dan Jue, and then took out a jade bottle to put away all the Yin Ghost Xuandan.

Yuwen Zhouyuan wiped the sweat from his forehead and laughed at himself: "It turns out that my alchemy is really good, and such a rare pill can be refined." ”

Yuwen Zhouyuan felt that refining the Yin Ghost Xuandan this time consumed a lot of spiritual power, which was more tiring than the other sixth- and seventh-grade pills he had refined at the beginning, although this Yin Ghost Xuandan was also a sixth-order pill, but he had never been so tired from refining seventh-grade pills.

Yuwen Zhouyuan hurriedly sat cross-legged and began to exercise to recover his cultivation, and after three hours, Yuwen Zhouyuan regained his strength, and then he entered the Absolute Yin Great Array of the Heavenly Book Space.

At this time, Yuwen Xiangwan was still practicing with her eyes closed, and the aura on her body had reached the peak of the late True Yuan period, and it seemed that as long as the time was ripe, she would have the hope of advancing to the real stage of the real person.

It seemed that she sensed the arrival of Yuwen Zhouyuan, and after Yuwen Zhouyuan came in, she opened her eyes, then got up and said with a smile: "Brother, this is indeed a good place for cultivation, my little sister's injury is not only completely healed, but also her cultivation has reached the peak of the late stage of Zhenyuan, thank you brother so much!"

"Thank you for not having to, I just provided you with the conditions for cultivation, being able to have such a cultivation is inseparable from your talent and hard work, this is the Yin Ghost Xuandan that I refined for me, this pill is good for you to advance to the real life stage, as well as to recover from your injuries after injury, hurry up and accept it." Yuwen Juyuan said as he handed her a jade bottle,

After hearing the words "Yin Ghost Xuandan", Yuwen Xiangwan's eyes flashed, and he said: "Yin Ghost Xuandan, that is what our ghost cultivation needs the most, I didn't expect that brother, you can still refine this kind of pill, brother, aren't you an alchemy master?"

"Hehe, as for whether my brother is an alchemy master, I don't know, brother, I just have a hobby for alchemy, and it is better to ask for alchemy, so I cultivate this Dan Dao. "Yuwen Zhou Yuan Dao.

"I see, my brother and sister have now recovered their cultivation, saving people is like fighting fires, it can't be too late to find the Soul Flower, the little sister will go to the Yin City to find out the news first. "Yuwen Xiangwan said to Yuwen Zhouyuan.

"Okay, then let's go together!" After Yuwen Zhouyuan finished speaking, he took Yuwen Xiang Wan out of the Absolute Yin Array, and then released his divine sense, and after identifying the direction, he flew towards the northwest sky of the Twilight Sun Realm.

A few hours later, he came to a desert in the northwest shrouded in thick black fog, Yuwen Zhouyuan sensed it, the yin spirit power here is extremely strong, it seems that this is the entrance to the yin city of that place!

Then Yuwen Zhouyuan took out the cloud and mist tent, got inside, and at the same time transported the hidden magic skill himself, and then followed Yuwen Xiangwan, who released the ghostly spirit, into the thick black mist.

Entering the black mist, Yuwen Zhouyuan passed through the cloud and mist heavenly tent, he sensed that the rules of heaven and earth here were completely different from the outside, the yin qi was extremely heavy, and at any time he would see wisps of remnant souls flying by, some of the remnant souls turned into energy and merged into the dense fog in flight, and some devoured other remnant souls and became stronger.

Yuwen Xiangwan flew in this yin fog, it seemed to be very comfortable, because she showed the peak cultivation of the True Yuan Period, although she encountered a lot of ghosts and ghosts along the way, but after they saw Yuwen Xiangwan's cultivation, they all avoided it from afar.

The cloud and mist tent turned into a faint black cloud, which blended well with the dense fog, if it wasn't for a person with a strong sense of consciousness, he wouldn't have noticed that Yuwen Xiangwan was still hiding by his side.

Half an hour later, a massive city came into view.

At a glance, covering an area of hundreds of square miles, the city wall is made of huge black stones, more than ten zhang high, far away, you can feel the amazing momentum rushing to the face.

On the main gate of the city wall are engraved three blood-colored characters: Earth Yin City!

Here in the Twilight Realm, this city is famous, because this city does not strictly belong to the Twilight Realm, but belongs to the Yin Si Ghost Domain, because this city is built on the Twilight Sun Realm and the passage to the Yin Si Ghost Domain.

In the past tens of thousands of years, due to the continuous penetration of the Yin Si Ghost Domain into the Dusk Sun Realm, the area of the ghost mist has continued to grow, and it has eaten away at a large area of land in the Dusk Sun Realm, and this Yin City has played a great role.

Although the Yin Si Ghost Domain has encroached on a lot of places in the Twilight Realm, those ghosts do not dare to go out to do evil at will, thanks to the fact that there was a True Self Stage senior in the Twilight Realm back then, who discovered the passage of the Yin and Yang Realms, and led the two monks of the Twilight Sun Realm to join forces to kill.

Those haunting ghosts and ghosts must not return to the ghost realm, and the two sides temporarily stop fighting, but people and ghosts have different paths, and they must be distrustful of each other.

The monks wanted to do it once and for all, and rushed into the mist under the leadership of the true self senior, but they found that whether it was a ghost, a ghost pawn, or a ghost general, their strength had greatly increased.

The monks attacked several times, but they were all defeated, and those ghosts and ghosts also attacked the monks many times in retaliation, but they did not take much advantage, because there was no fixed rear, and finally they all returned defeated.

In desperation, these ghosts had no choice but to retreat to the second, near the passage between the Dusk Yang Realm and the Yin Si Ghost Domain and not far from the encroaching boundary, they used their great magical powers to build this Yin City.

After the establishment of the Diyin City, when the monks attacked the Yin Ghost Creatures again, the Yin Ghost Creatures took advantage of the geographical advantage to block the attack of the human beings and consolidate their gains from encroaching on the territory, and since then the ghosts have started a confrontation with the human monks based on the Diyin City, and this confrontation is tens of thousands of years.

Ten thousand years ago, there was a huge war between humans and ghosts, and after this battle, both sides suffered casualties, but in the great war, among the human monks, a true self was born in the early stage.

This person turned the tide in the great war, brought the precarious human monks out of defeat, and defeated the Yin Si Ghost Domain, which was in full swing at that time, and forced the ghost marshal who led the ghost army at that time to sign a pact of non-invasion for 10,000 years, and then a hundred miles away from the Earth Yin City, the human monks also built a Tianyang City.
