Start to live forever, live till the end of time

But he heard that there are also middle-grade spiritual stones, and the generally accepted ratio is one to one hundred. But if he really wants to exchange them, the medium-grade spiritual stones can be easily exchanged for 120 low-grade spiritual stones.

He and the big black bull hid in an uninhabited corner, their eyes constantly scanning all directions, and he held the mountain ax tightly in one hand.

"Lao Niu, we are rich." Chen Xun whispered happily.

"Moo~" the big black bull whispered, its head lying in Chen Xun's arms, its eyes full of joy.

The biggest function of low-grade spiritual stones is that they can be used for cultivation. The pure spiritual power is much better than the spiritual energy of heaven and earth. They have to constantly refine the impurities in the spiritual energy during their cultivation.

But that is what the big players in the world of cultivating immortals do. Ordinary cultivators can only use it to trade, because the effect of the elixir is better, but it will be drug-resistant.

And those who can take elixirs until their body develops drug resistance are also super wealthy. Drug resistance is not considered by ordinary cultivators at all.

The next day, they continued to sell brochures, and finally collected a hundred low-grade spiritual stones. Chen Xun's whole body was shaking with excitement, and the big black bull kept mooing and circling around Chen Xun.

"Old Niu, we must keep a low profile."

Chen Xun said furtively, feeling like everyone was coming to steal their spiritual stones.

"Moo! Moo!" cried the big black cow, it understood.

On the third day, they did not sell any more brochures, but visited various stalls. Suddenly, Chen Xun's eyes lit up and he saw a familiar "old man".

"Girl, it's you."

The girl's appearance has not changed much, she is still the same as before. There are several elixirs and bottles of elixirs placed in front of the stall.

Her expression was shocked. The familiar legs were still the same, and the familiar four black cow's feet were still there. An idea popped up in her mind - why did the bandit come with the cow again?

"Haha, it's you." The girl forced a smile. This look was so deeply rooted in people's hearts that it was hard to forget.

"We are here to buy something. We have spiritual stones."

"Okay, what do you want to buy?"

The girl's eyes lit up and she felt energetic instantly, as long as he wasn't teasing her.

"Can you introduce these three elixirs to me..."

Chen Xun squatted down and smiled awkwardly, but he had studied medical skills and could still see something.

In the girl's surprised eyes, Chen Xun took out a few spiritual stones from his crotch and proved to her that he really had them.

"good……"

The girl was embarrassed, her eyes moved down, and she pointed at an elixir, "This is water cloud grass, twenty years old, it is the material of the Qi Gathering Pill."

"This is frost maple grass, but it is only ten years old. It is the material of Chongyu Dan."

"This is Shenhui grass, thirty years old, and the material of Chongyu Dan."

The girl introduced them one by one. Although she was not old enough, it was not easy for a casual cultivator to pick so many elixirs.

If there were more years, many monsters and spiritual beasts would come to fight for it.

"Girl, how many spiritual stones are there, I want them all."

Chen Xun licked his lips and stared at the elixir. This year seemed to be particularly easy to judge, just as he expected.

"Twenty." The girl thought for a while and shouted directly.

"What?!"

Chen Xun stood up and exclaimed. The harsh voice made the girl frown. She said softly: "How much do you give me?"

"Eight dollars."

"What?!"

It was the girl's turn to stand up and exclaim, "Is there such a bargain? Why don't you go and grab it!"

Chen Xun looked embarrassed, reached for his crotch with one hand, took out a few spiritual stones with difficulty, and said, "Ten spiritual stones, I only have so many."

The girl's chest rose and fell slightly, observing Chen Xun's expression, but nothing could be seen, only the nose, eyes, and mouth were exposed.

"Okay, then it's a deal." The girl nodded heavily.

"You give me three more boxes, I can't put them in..."

Chen Xun looked at the medicine box behind her, and he had been coveting it for a long time. He was indeed a seller of elixirs. This was called professionalism.

The girl's eyes widened. This man was really a bandit. He was plucking his hair, but she still gave it away and gave Chen Xun a sweet smile in the end.

"Old Niu, it's time to save money, and it's time to spend time, do you understand?"

"Moo!"

The big black bull arched Chen Xun dissatisfiedly. They had been in the mortal world for so long and had long understood this truth.

"Brother, how do you sell this fireball technique?" Chen Xun walked to a stall selling spells, his eyes unwavering.

A middle-aged man glanced at Chen Xun, his pupils widened slightly: "Four low-grade spiritual stones."

Chen Xun looked troubled, with hesitation in his eyes. The big black bull pulled Chen Xun, let's go! Walk!

"Fellow Taoist, wait a moment."

The middle-aged man looked at Chen Xun and then at the big black cow, "You really want it?"

"Well, I'm a little sincere." Chen Xun nodded.

"Take away the two spiritual stones!"

"Brother, please be happy."

Chen Xun praised, touched two spiritual stones from his crotch, took the spell and left directly, finishing in one go.

The middle-aged man shook his head slightly and took out another book "Fireball" from under the stall. He could print countless copies of this crappy little spell.

Chen Xun and Da Hei Niu bought a book of spells from various stalls and never bought more.

"The Art of Controlling Objects", "Basic Alchemy", "Elixir Encyclopedia", "Spiritual Art", etc. I also spent a lot of money to buy a bag of elixir seeds, and the hundred spiritual stones were quickly bottomed out.

Chen Xun and Da Hei Niu were walking in the valley, their hearts beating rapidly. They felt that their family was too rich and there were countless casual cultivators who wanted to rob them.

"Old cow."

"Moo~"

One person and one cow looked at each other deeply, their pace gradually quickened, and they rushed out of the valley, and then disappeared. This time, the top ten immortal sects ran away before they showed up.

…

On the outskirts of the Ningyun Mountains, a beast's nest was occupied by them. A huge stone sealed the entrance of the cave, making it impossible for ordinary people to move it.

The boulders are all covered with vines, and they are so densely packed that if you weren’t looking for it, you wouldn’t have noticed there was a cave here.

Crack!

The fire light came on, and the entire cave was illuminated brightly. Chen Xun's face was red, and the big black cow kept spinning and running like a chicken.

"Old Niu, don't show off your wealth and keep your mind stable."

Chen Xun said with a trembling voice, "Looking at you, when will you be like me?"

"Moo~~"

The big black bull kept rubbing against Chen Xun, extremely happy, "Moo!"

"We have 15 points of essence of all things, which adds up to 30 points, which can accelerate the growth of elixirs for more than two years in one day."

Chen Xun became more and more excited as he talked, spitting everywhere, "Old Niu, can you do arithmetic? How many years is one month?!"

"Moo?" The big black cow barked twice, wrote and drew on the ground with stones, and began to do arithmetic.

"75 years!"

Chen Xun said excitedly, looking at the big black cow, "One hundred-year-old elixir a month, my God."

"Moo? Moo!"

The big black bull was suddenly startled, and the pebbles fell to the ground. They had found out that a hundred-year-old elixir contained about one hundred to two hundred low-grade spiritual stones.

They also have spiritual medicine seeds, which they sell and buy again, in an infinite cycle. Who in this world of immortality has more spiritual stones than them.

"Don't think too much, we don't have the strength to guarantee large sales."

Chen Xun looked at the big black bull's expression and knew what he was thinking, "Just shoot for another, so that it won't attract attention. Besides, we have to make elixirs ourselves."

"Moo!"

The big black cow kept nodding, his eyes widened, and he was so stunned that he almost drifted off.

"Let's first cultivate the three elixirs in the medicine box to a hundred years. Those elixir seeds will come one by one."

Chen Xun said calmly and calmly, the strange medicinal fragrance of the hundred-year-old grass planted outside can attract the attention of many monsters and spiritual beasts.

This kind of medicine box can not only preserve the properties of the medicine, but also block the fragrance of the medicine. I will get more of them in the future, Chen Xun thought in his heart.
