After flying intermittently for five days, Mao Laoliu, who was wrapped in white gauze, finally arrived at Huangdao City!

"Ah! This is Huangdao City?"

Mao Laoliu stood outside the imposing Zodiac City Gate and looked at the largest Ghost World City within a radius of ten million miles in amazement..

Huang Dao City was about 300 feet tall, and the entire sky was shrouded in black clouds. It looked like an ancient beast lurking there!

Outside Zodiac City, the bustling ghost cultivators were lining up to enter the city. Mao Laoliu's entire body was wrapped in a ball of white light. He followed the crowd and handed over a hundred low-grade soul stones before entering Zodiac City!

Huang Dao City was very large. Even Mao Laoliu's spiritual awareness, which was more than ten miles long, could only see a corner of the city gate. He could not see the entire Huang Dao City clearly!

From the cultivation of the cultivators in the city, one could tell that Huang Dao City's cultivation level was not comparable to Ghost Head City's..

Mao Laoliu had only casually walked around and already saw more than ten Ghost General cultivators. Even Ghost King cultivators saw one or two..

"Huang Dao City is indeed awesome. I must be careful in this city!"

Mao Laoliu reminded himself. However, the ghost cultivators in the city were all strange. No one paid attention to why he wrapped himself in a ball of white light..

Mao Laoliu, who had been wandering around the stall for an entire day, walked towards a shop with a large facade..

He knew that the Vice Sect Leader of Ghost King Cave had betrayed his information. He also knew that his Ghost King Skull was a valuable treasure. Many powerful beings had their eyes on him. He had to sell those spirit stones as soon as possible and return to the human world the way he came!

To exchange for these spirit stones, he had to take a certain risk. Old Sixth Mao chose a shop that was slightly closer to the city gate..

" Welcome, Senior. May I know what Senior needs?"

There were quite a few ghost cultivators in the shop, all busy picking out their favorite treasures. A ghost soldier came up to greet Mao Laoliu politely..

"Okay, find a quiet private room and call your family's boss over!"

Mao Laoliu's words stunned the ghost soldier, but he immediately understood what he meant. He knew that this was a big customer!

"Yes, Senior, come with me!"

Ghost Soldier politely brought Mao Laoliu into a private room and opened the shielding array of this private room!

Senior, wait a moment. I'll go call my boss!"

Mao Laoliu didn't say anything. He released his divine sense to check the shop. This kind of shielding array could block the inside from seeing the outside, but the outside couldn't see inside..

Not long after, an early-stage Ghost King female cultivator walked in. She looked normal and was surrounded by black gas..

"Welcome, Fellow Daoist. I am the owner of this shop. My name is Witch Ji. May I know what you have to say?"

" Witch Ji? Not a bad name. Let me ask you, does your house accept anything?"

" Hehe, Fellow Daoist, you must be joking. How can there be a shop that doesn't accept things?"

"Alright, how many Soul Stones are these things worth?"

Mao Laoliu didn't hesitate at all. He took out the ghost cultivation supplies that he had stolen from the Ghost Head City Lord and the Jiu Family Head and handed them to the early-stage Ghost King female cultivator..

"Oh? They're all good things, they're all Ghost King's things. Fellow Daoist, wait a moment!"

The female cultivator stood at the door and casually called another ghost general cultivator in. She handed the storage bag to the ghost general and asked him to start counting..

Mao Laoliu didn't care either and waited patiently..

" Fellow Daoist looks unfamiliar. This should be your first time visiting my house!"

" Yes, I've been cultivating in the mountains for decades. This is the first time I've come to your house!" Mao Laoliu said indifferently..

：.

" Oh? I told you, you look unfamiliar!" The female cultivator shop owner said without saying anything..

Fellow Daoist, do you have any advanced soul attack techniques?"

" Sigh, Fellow Daoist, what a coincidence. A few days ago, we just received a soul attack secret technique that might be from the spirit world. We were planning to send it to the auction tomorrow, but…"

" Oh? Why is it possible? What's the difference?"

Mao Laoliu's heart immediately moved. If it was passed down from the Spiritual Realm, it must be an extremely powerful secret technique!

"Fellow Daoist, the reason why this secret technique might have been passed down from the Spiritual Realm is because the seal on it can't be opened at all. We even suspect that it was passed down from the Immortal Realm!"

The female cultivator smiled as she looked at Mao Laoliu in the white light!

" What? They could all be passed down from the Immortal Realm? Can you bring them over for me to take a look?"

"Yes, but the price is too high. I'm afraid Fellow Daoist won't be able to accept it!"

"Hahaha, as long as there's a price, it's fine. Take it over and have a look!"

" This?" The female cultivator hesitated.

" What?" Old Sixth Mao looked at the female cultivator in confusion..

"Fellow Daoist, this might be a secret technique of the Spiritual Realm. The starting bid for the auction is 10 million low-grade soul stones!"

" Oh? The price is indeed not low! Take it and have a look!"

Mao Laoliu said domineeringly, causing the Ghost General cultivator who was checking his storage bag to look up at Mao Laoliu..

" Alright!" The female cultivator hesitated for a moment. With a flip of her hand, a jade box appeared in her hand and she carefully handed it to Mao Laoliu..

Mao Laoliu did not hesitate and opened the jade box directly. An antique jade slip that looked like a white stone was placed inside!

"Jade slip?"

Mao Laoliu was ecstatic. In his mind, most of the cultivation techniques and secret arts in the human world were inherited through books or animal skins. Once one could use jade slips, they would at least be things from the spiritual world..

Fellow Daoist, can I have a look?"

" Fellow Daoist, feel free!" The female cultivator generously raised her hand and made a gesture of invitation..

Mao Laoliu was not polite and directly held this jade slip to his forehead. A cool feeling welled up in Mao Laoliu's heart. This jade alone was not ordinary. It was probably the kind that could refresh and improve his eyesight. Refreshing jade.

"Soul Seal?"

Just as the jade slip was stuck on Sixth Brother's forehead, three words appeared in Sixth Brother's Soul Consciousness. Behind those three words, there was a ball of white fog, as if it was a powerful seal!

" The white fog behind this is the seal?" Lao Liu Mao put down the jade slip in his hand, but he had no intention of returning it to the female cultivator..

" That's right. That's a seal. If Fellow Daoist buys it, whether or not you can open it depends on your luck. We can't open it anyway!" The female cultivator at the early Ghost King stage said frankly..

" What about the price? Can it be lower? After all, I'll buy it. Whether I can open it or not is still up to discussion!"

"Sorry Fellow Daoist, this is a gamble. If you lose, you will lose ten million at most. However, if you bet correctly, there is a possibility that the divine soul attack secret technique of the Immortal World will be used. You will earn a lot. That is not measured by soul stones..

”

" Let's gamble. If we lose, there's a lower limit. If we win, there might be no upper limit!"

Sixth Brother was tempted. He could earn more if he lost the Soul Stone, but if he missed it, he would have no chance. If it was a secret technique passed down from the Immortal World, he would make a huge profit!

" Fellow Daoist, how do you exchange spirit stones?" Lao Liu Mao suddenly asked.
