Mortal Cultivation: Who Can Be More Yin Than Me, the Extreme Yin!

Song Wen curled his lips and did not let the Dark Fox come out again.

Even the beast Dark Fox could tell that this was a poison pill, so the toxicity of this pill must be quite high.

Song Wen took out a jade bottle, put two pills in it, and flashed out of the cave.

It was dusk at this time, and the sunset on the horizon was as brilliant as molten gold, dyeing the sky orange and red.

Song Wen looked up and saw Zhou Siyi on the top of the mountain. He flew to Zhou Siyi's side and asked.

"Sister, why are you so elegant today and come to the top of the mountain to enjoy the scenery alone?"

Zhou Siyi's bright eyes turned slightly and gave Song Wen a big roll of the eyes.

"I don't have any elegant interest. Recently, the growth of the Shadow Gu's strength has obviously slowed down. I can't find a solution, and I feel a little depressed. I just come up to relax."

The Shadow Gu has been advanced to the third level for many years.

In these years, following Song Wen, the Shadow Gu has eaten a lot of corpses of cultivators and monsters, various spiritual herbs and pills. Although the strength has hardly increased, it has greatly increased the foundation of the Shadow Gu.

After Zhou Siyi took over, the Shadow Gu she cultivated grew rapidly in strength.

Originally, Zhou Siyi expected that it would take two or three years for it to advance to the third stage.

However, as time went on, the growth rate of the Shadow Gu's strength slowed down significantly.

This made Zhou Siyi a little distressed.

"Sister, take your time, don't rush."

As he said that, Song Wen took out the pill he had just refined.

"Sister, can you help me take a look at this pill."

Zhou Siyi took the pill, looked at it, and asked.

"Is this the Blood Demon Pill you made according to the new pill formula of Huitian Pill?"

After getting Song Wen's affirmative response, Zhou Siyi looked puzzled.

"How could this be? This pill has rich spiritual energy, but it is extremely toxic. It is obviously not in line with your original intention of developing this pill. What are you going to do?"

"I plan to try the medicinal properties of this pill first, and then make the next plan." Song Wen said.

"How about I order someone to capture two medicine slaves to test the efficacy of this pill?" Zhou Siyi asked tentatively.

"The toxicity and efficacy of this pill are not something that ordinary cultivators can resist. There is little point in finding medicine slaves." Song Wen shook his head and rejected Zhou Siyi's proposal.

"What should I do then?" Zhou Siyi couldn't think of any other way for a while.

"I plan to find a fourth-level monster beast to test the toxicity of this pill first. If the fourth-level monster beast can resist its toxicity, I plan to test the medicine myself." Song Wen said.

Zhou Siyi's expression became a little worried when he heard this.

"Junior brother, you have to think it through. Monster beasts and humans have different resistance to toxins. If the poison can't kill a fourth-level monster beast, it doesn't mean that it can't kill a Yuanying cultivator."

Song Wen said, "Thank you for your concern, senior sister. I know the severity. When I try the medicine myself, I will break the pill into pieces and reduce the dosage. However, fourth-level monster beasts are not easy to find."

Near the Lost World Ridge, there are large sects surrounding it, so there is no room for powerful monster beasts to survive.

In fact, not only in the Lost World Ridge, but also in the entire Tianyuan Continent, fourth-level monsters are rare.

The main place where monsters live is in the Tuocang Mountains.

However, the Tuocang Mountains are crowded with monsters and full of dangers. Song Wen is unwilling to easily get involved just to test the medicine.

"I do know where there are fourth-level monsters." Zhou Siyi said.

Song Wen's eyes lit up, "Where?"

Zhou Siyi said, "Junior brother, don't be too happy too early. All fourth-level monsters that can occupy our human territory for a long time have their own unique way of survival. Otherwise, they would have been killed to take spiritual materials and refine magic weapons."

"Senior sister, don't keep me in suspense. Just tell me where there are fourth-level monsters." Song Wen said.

"The Fiery Cave of the Beast Taming Sect, the Netherworld Ghost Domain of the Xuanyin Sect, the Frozen Ancient Realm of the Xuantian Sword Sect..." Zhou Siyi said several place names in a row.

After hearing this, Song Wen looked a little bitter. The place names Zhou Siyi mentioned are all famous Jedi in the world of immortal cultivation. Few people who enter without permission can come back alive.

Zhou Siyi smiled slightly, "Junior brother, you have fallen into a misunderstanding. In fact, it is not necessary to use a fourth-level monster to test poison. Some special third-level monsters are not necessarily less resistant to toxins than fourth-level monsters."

Song Wen nodded, "Senior sister, what you said makes sense. But where can we find a third-level monster with strong resistance to poison?"

Zhou Siyi said, "It is said that there is a third-level poisonous dragon in the Pure Sea. Junior brother may try your luck."

The Pure Sea is not a sea, but a freshwater lake.

However, its area is extremely vast, tens of thousands of miles, so it is called a "sea".

The Pure Sea is located in the territory of the Hehuan Sect, about two million miles away from the Lost World Ridge.

With Song Wen's current speed, he can get there in one day.

"Junior brother, are you planning to go to Jinghai?" Zhou Siyi asked when Song Wen seemed to be interested.

Seeing Song Wen nod in response, Zhou Siyi said again.

"Two days ago, Fang Pengyi sent someone to bring the news that the spiritual medicine seeds for trading with us have been prepared. However, he refused to come to Yishiling to trade, and asked me to go to Donghua Market to trade face to face. Junior brother, will you accompany me to Donghua Market?"

A few months ago, Fang Pengyi and Zhou Siyi had agreed on the terms of the transaction.

Fang Pengyi provided seeds of 25 third-level spiritual medicines and 13 fourth-level spiritual medicines. Zhou Siyi had to pay 100 high-quality spiritual stones for this.

Zhou Siyi was worried that it was not safe to go to Donghua Market alone. So, he asked Song Wen to accompany him.

"Okay." Song Wen replied.

The two of them packed up their luggage and set off with Song Wen driving the spaceship.

The spaceship driven by Song Wen was a medium-grade magic weapon. When he drove it, the speed was not much slower than his full-speed escape.

In three days, the two arrived at Donghua Market.

Zhou Siyi used the communication jade slip to agree on the time and place of the transaction with Fang Pengyi.

The next day.

Zhou Siyi went to a hill outside the market alone.

When she arrived, Fang Pengyi was waiting on the top of the hill.

"Fellow Daoist Zhou Shuang, did you bring the spirit stone?"

Zhou Siyi raised her hand and waved it, and a white mist appeared out of thin air, covering the entire hilltop to prevent others from snooping.

"Of course I brought it."

As soon as Zhou Siyi finished speaking, a hundred high-grade spirit stones appeared in front of him.

The spirit stones were only displayed for a breath or two, and then Zhou Siyi took them back.

"Where are the seeds I want?" Zhou Siyi asked.

Fang Pengyi flipped his hand and a three-foot-high jade box appeared in his hand.

The jade box was opened, and its interior was divided into six or seven forty-two small squares.

In these small squares, there were various kinds of seeds.

There were sesame-sized ones and peach-sized ones, a total of thirty-eight kinds of seeds.

The number of each kind of seeds was also different, some had more and some had less, some had fifty, and some had only twenty.

After confirming that the types and quantities of seeds were the same as agreed, the one hundred top-grade spirit stones appeared in front of Zhou Siyi again.

In front of Fang Pengyi, she put the spirit stones away in a storage bag, and said to Fang Pengyi with the storage bag.

"Fang Daoyou, how about you and I throw things out at the same time?"

Fang Pengyi shook his head, with a sneer on his lips.

"Zhou Siyi, Elder Zhou!"

"A mere one hundred top-grade spirit stones can't buy so many seeds of third- and fourth-level spirit medicines."
