The system gives me immortality, and I will eventually become invincible while I’m alive.

Chen Xun and Da Heiniu also headed towards the central city. The west was bustling and bustling, and Chen Xun saw many sect disciples.

The big black bull's eyes were full of hope, looking to the west. If possible... even if they could see a few familiar people.

He and the big black bull did not communicate. They looked around as they walked through the wide streets, and countless monks passed by them.

The more monks there are in such places, the less likely they are to let their spiritual consciousness wander around without a specific target. This is an extremely serious act of provocation, unless you are really the eldest brother and are not afraid of public anger.

"Old Niu, let it take its course. They should all have made a breakthrough. Who in this world of cultivating immortals is not better qualified than us, haha."

"Moo~"

"I haven't opened the ancient book yet. I just want to give him a big surprise next time I meet him, and then return it to him!"

"Moo!"

"Then let's say, yes, we are the legendary shocking old monsters. Juniors, tremble, hahaha..."

"Moo~~"

Dahei Niu also laughed, but suddenly looked at Chen Xun with a little doubt in his eyes. If Chen Xun really wanted to, he could quietly return to the Wuyun Sect.

Chen Xun's heart sank, he patted the bull's head and began to change the subject: "Oh, I'll go, old cow, look at that auction hall!"

"Moo?" The big black cow stopped thinking about it and his eyes were attracted away.

They stood at the corner of the street. The central city was still a little far away, but they could already see the open auction hall.

Its name is Taigu Hall, and it is a very ancient hall that is well-known in the world of immortality in various countries. It is said that it has been standing here since the beginning of the city's founding. The ten major immortal sects jointly manage and maintain it, and have never let outsiders get involved.

That kind of ancient heritage is really not comparable to ordinary weapon refining things. Even if you look at it from a distance, you will be awe-inspiring and immersed in it, feeling the changes of the world of immortality over the years.

Taigu Hall is overall black and gold in color, with a very grand and rigorous layout. It is even taller than the city wall, overlooking the visitors from the Western Sea and the Eight Wildernesses.

Normally, Taigu Hall is not open at all and is surrounded by a large formation. Now it is truly revealed to the public.

Chen Xun swallowed hard and his eyes widened, as did the big black bull.

They looked at each other silently, both thinking the same thing: Can monks build this kind of building? !

"Old Niu, let's get closer and take a look, otherwise it will be a big pity."

"Moo!"

With shock in their eyes, they looked up at the Taigu Palace in the distance as they walked. Chen Xun and Da Hei Niu really liked looking at the city walls and buildings.

They always feel that there are countless stories and wisdom hidden in it. Perhaps they are the only ones in the entire world of immortality who can calm down and do such a waste of life.

The central city is quite open, with almost no streets, pavilions and pavilions. It is full of various giant buildings standing in the west. Even the restaurants and posthouses have their own spirit gathering formations, which is extremely luxurious.

Most restaurants have viewing platforms. Many people with the aura of superiors sit there and look at the ground. They have sharp eyes and there are many servants around them.

To the north of the Taigu Palace are the major fighting arenas. The geniuses from all the major forces and sects are ready to show their faces. There are also some hidden geniuses who are ready to make a splash at the grand event and "shock" everyone.

The surrounding area was crowded and quite lively, but stalls were prohibited. There were disciples from the top ten immortal sects stationed everywhere, and there were even great golden elixir monks.

To the west of Taigu Palace is the place where flowers gather. To the west of the city, flowers are blooming all over the place, and a long river flows through it. It is a completely different world from the Tianduan Plain, which is extremely strange.

"Senior Kong Yongyuan is a little too arrogant."

"This person is only in the middle stage of the Golden Core. How dare he claim to be invincible? I don't quite understand."

"Have you forgotten Mr. Yudong of Mo Yuxuan? The Fusang Tianlin Technique is an incredible magic."

"Young Master Yudong is also a Heavenly Spiritual Root. I heard that he studied under a certain Nascent Soul Ancestor from abroad. It seems that this event will be another battle between dragons and tigers."

……

There was talk in the west of the central city, and the focus was always on those talented people. Chen Xun and Da Hei Niu sat in a corner of the city and silently watched the main hall.

They had itchy hands and wanted to touch it, but Taigu Hall was surrounded by sect disciples who were guarding it, so they had no choice but to give up.

"Old Niu, we still have two elixirs left. We will also attend the auction then."

"Moo~"

"However, this auction conference is also very mysterious, and there is no auction list in advance."

Chen Xun sighed deeply, his eyes still on Taigu Palace, "The entrance fee is one thousand low-grade spiritual stones..."

"Moo~" The big black cow also lamented, put its hooves on Chen Xun's shoulders, and comforted him.

"Old Niu, it's okay. You can earn more spiritual stones. Am I the one who is short of spiritual stones?"

Chen Xun didn't care in his eyes, but subconsciously pinched the storage bag, as if he was worried that it would run away.

"Moo!" The big black bull snorted and nodded heavily. There are hundreds of thousands of low-grade spiritual stones, so don't handle them harshly.

One person and one cow stopped showing off, and they looked at Taigu Palace with their arms around each other. The more they looked at it, the more interesting it became, but the image was really not that good, it was just a broken bowl in front of them.

As the days passed, the entire Yuxu City gradually became turbulent. The clouds in the west moved with great force, and the central city was full of tension.

There are so-called geniuses in the world of immortality everywhere. They walk like a wind, are arrogant and sharp, and are followed by a large number of people.

Now Chen Xun and Da Hei Niu have to walk slower and breathe more evenly, so as not to bump into some big brother, mock them a few times and then be pulled to the fighting stage.

I'm afraid what if I don't control this and accidentally beat these geniuses to death, wouldn't that be embarrassing...

A large formation was rampant outside Taigu Hall, and monks gathered together. They were entering the venue through the formation restrictions, and the auction meeting was divided into two parts.

The side hall is the meeting place for monks in the Qi Refining Stage and Foundation Establishment Stage. They have a table at this level and only need to pay 300 low-grade spiritual stones to enter.

The main hall is the venue for the ancestors of the Jindan period and Nascent Soul. The real power of each country is at the top. 1000 low-grade spiritual stones are required to enter.

Chen Xun also changed his identity and became a great monk at the Golden Core stage again, but Da Hei Niu was still at the Foundation Establishment stage.

They inquired that the spirit beasts followed the monks to enter without paying much fees, which was quite humane.

Outside the main hall, the foundation building stages of the ten immortal gates are constantly greeting the seniors, and those Nascent Soul Ancestors have already entered through another gate.

Looking around, there are hundreds of golden elixir monks, which is quite terrifying.

"Senior, are you here to participate in the big auction?" A woman in a purple shirt came over enthusiastically and saw that Chen Xun had been standing outside for a while.

"Yes, I don't know what the rules are." Chen Xun nodded and smiled, then glanced around again.

The big black cow didn't dare to look around at this time. The cow's tail was hanging down and it stared blankly at the woman in purple shirt.

"Senior is a great golden elixir monk. You only need to pay one thousand spirit stones to enter. There are no extra rules."

"Okay, this is the spirit stone."

Chen Xun waved his hand and took out the spirit stone from the storage bag. The woman in purple also took out a storage ring and took it, and gave Chen Xun a jade token:

"Senior, this is your room's forbidden jade sign, with the geo character sequence 357."

"Oh? It is indeed one of the top ten immortal sects."

Chen Xun's eyes lit up and he quickly took it, "Thank you."

The woman in purple shirt showed a sweet smile and stretched out a hand: "This is what I should do as a junior. Senior, please come into the palace."

Chen Xun patted the big black bull, and they stepped forward, injecting a trace of mana into the jade tablet, and instantly walked into the formation's light curtain.

Now they were shocked to see the Taigu Palace up close, but there were too many monks around and they didn't stay too much.

The Taigu Hall is quite empty, like the Colosseum in ancient Rome, but the viewing platform is full of various rooms, and the outside is full of restrictions that block spiritual consciousness.

Chen Xun took a cursory glance and found that even if there were various rooms, it could probably accommodate tens of thousands of people. It was really ridiculously big.

Golden elixir monks came in one after another around them, and they were all silent, but there was no Yuanying ancestor in sight.

"Old Niu, I guess those Nascent Soul Ancestors are in the top room."

Chen Xun raised his head and looked at the top of the viewing platform. Those rooms looked quite oppressive from the outside.

"Moo~" Da Hei Niu's eyes were a little nervous. This was a legendary figure, even more powerful than Master Qingtian of Panning City.

"Old Niu, let's go to the room first."

"Moo~"

There are steps everywhere in the main hall, and you can go up anywhere. Chen Xun followed the serial number of the jade plaque and finally found their location in the center of the viewing platform.

Chen Xun and Da Hei Niu stood on it and took a look again, with a hint of excitement in their eyes. They really gained a lot of knowledge, and a thousand spirit stones were not such a loss.

As soon as the restriction outside the room touched the jade sign, a hole was opened immediately, and Chen Xun and Da Hei Niu jumped in instantly...
