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

"Moo~" The big black cow also nuzzled Chen Xun, with joy in his eyes.

"Old Niu, have you remembered the road from Nancheng to Dongcheng?" Chen Xun joked, "Our energy has increased greatly after our breakthrough, so we don't need to rest every day."

"Moo!" The big black cow gave Chen Xun angrily. It knew the way and had never been afraid of anyone before.

"Old Niu, let's go. I've chosen a few elixir shops along the way to sell the elixirs we've cultivated over the past six months."

Chen Xun began to transmit the message, "Anyway, they are all hundred years old and not worth much spiritual stones, but you have to spend some time to sell them separately, don't be careless."

The big black cow raised the corners of his mouth slightly and gave him a look that said, "I understand."

One person and one cow gradually disappeared into this noisy place. An hour later, they entered a bustling elixir shop. Even the big black cow walked in standing.

However, the people here are not weird at all. Anyone who can open a shop in Yuxu City is a well-informed person.

Several guys in the Qi refining stage didn't dare to come forward to greet him when they saw it was a senior foundation builder. They were not qualified yet.

"If you want to buy anything, fellow Taoist, you can go to the second floor to discuss it in detail."

At this time, an old man in white who was in the early stage of foundation building came over with a smile on his face and said, "There are only some Qi Refining Stage elixirs on the first floor. I guess they won't be able to catch the eyes of fellow Taoists."

"Fellow Taoist, please." Chen Xun nodded solemnly, as if full of thoughts.

The big black cow was also stunned. It would be difficult to tell something from its expression.

On the second floor, there were far fewer people. There were some elixir samples placed everywhere, and some elixir prescriptions for sale, but they were all marked with a layer of restrictions.

They walked into a small private room and sat on the floor. The old man in white poured a pot of tea and worked in an orderly manner.

Business in the foundation-building period is very important to them, and it is also a good thing. There is no shortage of human kindness and sophistication.

"I wonder if your store can accept elixirs?"

"Oh? It turns out that Taoist friend is here to sell elixirs."

The old man in white smiled slowly and said, "I wonder what kind of elixir it is and what year it is?"

Chen Xun still looked worried, with a flash of pain in his eyes. He took out three medicine boxes from the storage bag and placed them on the table.

The old man in white clothes had been secretly observing Chen Xun's expression for a long time, and he felt happy, maybe he was in trouble and wanted to sell something good.

The three medicine boxes opened with a click, revealing three elixirs.

"Mijingcao, 150 years old, Yuyuanhua, 120 years old, black sandalwood 100 years old!"

Chen Xun introduced them one by one, gritted his teeth at the end, and two bloodshot eyes appeared, "Fellow Taoist, please make a price!"

"Moo!" The big black bull also shouted from the side, gaining momentum.

The old man in white's pupils shrank, his eyes widened, and he almost yelled: That's it? !

Although these three elixirs can be used in the foundation building period, the year is too ordinary, and the old man in white feels very unlucky. He is really running away...

However, he still greeted Chen Xun with a smile: "Fellow Taoist, how about five hundred low-grade spiritual stones?"

"No, these three elixirs are absolutely perfect in terms of medicinal properties and completeness."

Chen Xun shook his head with a deep look on his face, "They can continue to be cultivated. At least another 50 yuan will be added. Fellow Taoist, please don't treat me as an ignorant person."

"Moo!" The big black cow shouted again with blazing eyes. It also felt that what its elder brother said was right.

The old man in white squinted his eyes slightly and used his spiritual consciousness to explore. After a while, he nodded: "It's indeed good."

In the end, both parties were happy, and the deal was completed with 550 low-grade spiritual stones. The old man in white also asked Chen Xun to come to their store if he had any more spiritual medicine.

Chen Xun had a stern look on his face and kept saying that he would do it next time. Then he turned around and walked away with the big black cow. The old man in white glanced at them and went to greet others.

On the street, Chen Xun and Da Hei Niu began to communicate.

"Old Niu, we can not only sell elixirs, but also elixirs."

"Moo? Moo!"

"My alchemy technique, I had a dream a few days ago. Putting aside the facts, the Alchemy Saint knelt down and begged me to preach."

"Moo?!" The big black bull's eyes widened, convinced, and even arched Chen Xun.

"That's the kind of strong person who is a thousand times stronger than me, but can't make alchemy as well as me."

Chen Xun started to brag, and the big black bull was stunned for a while.

Countless cultivators passed by them on the road.

A man was dancing and talking seriously, and a cow looked at the man seriously, with no doubt in his eyes. From time to time, laughter and moos could be heard.

In the next two months, they traveled all over Nancheng, selling three hundred-year-old elixir to major stores from time to time.

Because they were all going to big stores and they were quite far apart, no one really paid attention to poor foundation-building monks like them, and they never left the city.

Even if you are tired, you should still find a deserted corner to rest, look at the stars and the moon, plan the future, and restore your mana. The aura of Yuxu City cannot be wasted.

Now they already have three thousand low-grade spiritual stones in their possession, and they will keep them when they are good, and will no longer sell the spiritual medicine for the time being.

Moreover, Chen Xun had already discovered that the price of this elixir was much more expensive than ordinary low-year elixirs. The price-performance ratio was extremely high for him, and the risk was almost minimal.

Sometimes I also ask where the exercises are sold. The golden elixir exercises of the five spiritual roots should not be difficult, and their requirements are not high.

If possible, they wouldn't mind buying a spare copy of Nascent Soul Technique...

The sun is shining brightly today and everything is fine.

Two black figures walked out of the deserted corner. They seemed to always have smiles on their lips. Even if they were sleeping on the street, they were not as sad as those cultivators.

"Come on, Lao Niu, let's watch the exercises."

"Moo~"

They asked around and found out that there was a big store opened by Mo Yuxuan in Nancheng. It was in the north of Nancheng, close to Central City. It sold everything.

Two hours later, Chen Xun and Da Hei Niu stopped outside a rather impressive attic.

The attic has seven floors and occupies a considerable area. There is an endless stream of monks coming in and out, and they all know that the goods sold here are of high quality.

They stood on the edge of the street, watching from a distance.

"Old Niu, it would take tens of thousands of spirit stones to capture such a large piece of land."

Chen Xun looked up and exclaimed, it was really an eye-opener, "Let's go in and have a look too."

"Moo!" Da Hei Niu was shocked in his eyes and quickly followed Chen Xun.

This kind of city for immortal cultivators is completely different from the city in the mortal world, the gathering place for casual cultivators, and the inside of a sect.

For immortals like Chen Xun and Da Hei Niu, this is truly the most extreme experience and the purest enjoyment.

Walking into the pavilion, it was very lively. The big black cow also stood up. It is easier to walk when there are many people.

The first floor is specially opened for the Qi Refining Period. It sells a wide variety of things and is divided into several areas. There are even materials for monsters and spiritual beasts.

Chen Xun took the big black cow around the talisman area for a long time. There were quite a few seal pens, cinnabar, and yellow paper inside, all made of monster materials.

If combined with the blood of spiritual beasts, it is said that the effect of the talisman will be greatly increased.

"Old Niu, when we were in the Wuyun Sect, we didn't find that there were many monsters and spiritual beasts. There were only many in Nandou Mountain."

Chen Xun's spiritual consciousness sent a message to Da Hei Niu, "It is estimated that after so many years of development in Qian Country, some monsters have been exterminated."

"Moo~" Da Hei Niu agreed and glanced at the plaque outside.

"Old Niu, Mo Yuxuan is not from Qianguo. He probably has some ways abroad and should make a fortune."

Chen Xun smiled slightly and looked at the many talismans on the container with some envy in his eyes. He had actually dabbled in this a little bit, but there was too little material.
