When he felt someone coming, the old man opened his eyes slightly and closed his eyes again when he saw only the team in the great empire.

But Sun Yi didn't care about it. What he cared about was a treasure on the stall.

The yellow leaves, each of which is extremely narrow and long, are like the sharpest knife. There are countless lines on them, which are vaguely combined into a word "black". They are the famous black intestinal grass in hell, containing terrible toxins.

Judging from its year, it should be a black intestinal grass of 100000 years. If a strong man in the great empire eats it by mistake, I'm afraid the power of the avenue can't suppress the toxicity and will be directly poisoned.

Sun Yi's look flashed. He also heard about some treasures in hell during this period. This black intestinal grass happened to be one of them.

Although the poison is powerful, it is a great tonic for his holy emperor level flesh. With the help of the conflict between the poison of death and the life force in his body, he can harden his flesh and reach the holy emperor limit as soon as possible.

But he was deterred by the price at which the ginseng could be exchanged for 500000 years.

He didn't have the five hundred thousand year Hades ginseng. Although he had a lot of wealth, it was nine days. It was worthless in the hell world. He found that he was really poor now.

"It seems that we are going to make a fortune."

Shaking his head slightly, Hotan Nong left the Ming God business alliance and stopped outside.

"There is no way to accumulate wealth quickly in hell." Sun Yi asked Xiang Tiannong.

Tian Nong thought a little and replied, "there are no more than two ways to make money in hell, either plunder with strong strength, or be an alchemist or tool refiner."

"Wait, you said alchemy?" Sun Yi suddenly stopped.

"Yes, alchemy. We martial arts practitioners can't practice without pills, but there are very few alchemists in hell. Every hell pill they refine is looted by martial arts practitioners, so alchemists are also the representative of wealth in hell."

Due to its special environment in hell, many martial artists are difficult to understand the Dan fire that can be used for alchemy. Without Dan fire, alchemy cannot be done.

For example, only one person in the whole Shangshan city can refine the seven product pill, which is warmly entertained by the martial arts master of the whole city.

"Yes, I'll choose alchemy, but the pill in hell must be very different from the pill in nine days. I need to be familiar with it first." Sun Yi was overjoyed and asked Tian Nong to help him find some books about Dandao.

Here, danfang is not worth money and can't refine pills. No more cherished danfang has any effect, so Tiannong soon brought a lot of Dandao books.

In the next few days, Sun Yi locked herself in the room and digested those Dandao books.

"It turns out that alchemy in hell is such a thing. No wonder there are so few alchemists in hell."

Sun Yi smiled at the corners of her mouth. The alchemy here and Jiutian pill also have something in common, which is nothing more than compressing energy and removing impurities from the elixir.

But it happened that the dark people here have a cold constitution and are difficult to understand the flame that can be used for alchemy, resulting in the extreme scarcity of alchemists in the whole hell.

"Let me refine a batch of the simplest hell elixirs."

Sun Yi called mangling with a light and asked him to buy a Dan stove for himself. At the same time, the savings of mangling for so many years fell into Sun Yi's hands.

Mangling was surprised that his young master could refine pills. It was incredible.

After buying the Dan stove, Sun Yi waved to decorate a space and wanted to refine the pill.

The nether pill he refined is the most common and needed one in hell, which is to compress the nether Qi in the nether ginseng to the purest and remove the impurities. In this way, the refined nether pill martial artist does not need to refine at all, but can be directly transformed into rolling medicine into the body.

More than one million ten thousand year old ginseng and five hundred thousand year old ginseng are all the savings of mangling, and Sun Yi is preparing to refine them into a nether pill.

After selling the underworld pill, he can go to the underworld God business alliance to search for the unique treasures in hell and temper his powerful body.

Sun Yi immediately began to refine elixir. This kind of elixir that only removes impurities and purifies is not difficult for him. Daowei of life and death added to the elixir fire to burn the impurities, leaving only pure dark Qi without refining.

In just a few days, all the nether ginseng in his hand was refined into nether pill.

"Mangling, Tiannong, you two come in." Sun Yi rubbed his sore temples and called.

Soon, the two respectfully came to the room.

"Here is the nether pill I purified these days. You two go and sell it to me in the nether God business alliance." Waving, Sun Yi handed several jade bottles to mangling.

"What a pure hell pill. I saw such a pure hell pill for the first time."

You should know that the underworld pill can not only assist cultivation, but more importantly, if there are several pure underworld pills in the battle, it will replenish the underworld Qi in a moment. It is likely that several underworld pills will turn defeat into victory and kill the opponent.

"By the way, what's the price of these Mingdan?" Sun Yi asked.

"Generally speaking, the price of the pill made by the ten thousand year old ginseng is the price of two raw ginseng."

Tian Nong answered first, with a helpless look on his face. This is huge profits. But who makes there few alchemists in the hell world? Most of the purification results of other martial artists are directly scrapped.

"Well, you can exchange one nether pill for three nether ginseng of the same year." Sun Yi thought for a moment and said.

"Is that all right, my lord?" Tian Nong was not sure and swallowed his saliva.

"I said OK. You just sell it. Don't worry. Someone is definitely trying to get it." Sun Yi smiled strangely at the corners of his mouth. He was absolutely sure of his purified Mingdan.

The world's strong people never lack netherworld ginseng. Many things cannot be changed by netherworld ginseng. In particular, the several netherworld pills purified by netherworld ginseng for 100000 years will definitely make the martial artists in the realm of the great emperor crazy.

"Well, I'll try."

Tian Nong and mangling left. They didn't believe that one hell pill could exchange for three hell ginseng, and Sun Yi was waiting for them in the inn.

Three hours later.

"Sir, sir, you're right. They were all robbed! All sold out! "

An excited voice came out of the room. Tian Nong burst into Sun Yi's room excitedly. The excited expression on his face was hard to express.

Sure enough, just as Sun Yi expected, he and mangling had just entered the nether God business alliance and indefinitely shouted out a nether pill for three times the price of the same nether ginseng. In a short time, many martial artists came to watch. After they checked the nether pill, they immediately took out the nether ginseng and exchanged it without saying a word.

Just a few hours later, he was robbed. Many martial artists were still asking him if he had any Ming Dan, which made Tian Nong feel like a dream and didn't respond at all.

However, mangling was resourceful. After prevaricating a few words, he took Tian Nong back to the inn
