Forced to become a pure and innocent female pharmacist in order to cultivate immortality.

The main reason is that Ye Liuyun cannot tell Nalan Yan some things. Nalan Yan knows very little about her. If she knew about her abilities, she probably wouldn't be so worried.

Ye Liuyun was still gratified that she hadn't made a mistake in befriending Nalan Yan, a good friend, because at least she genuinely cared about her.

"Alright, I'll head back now. It's best if you don't leave Medicine Peak for a while; they'll definitely send people to ambush you," Nalan Yan said as a final word before turning and leaving.

After Nalan Yan left, Ye Liuyun was in a hurry. He blocked the entrance with an array and went into her newly opened alchemy room.

"No, Master, I have to try my hand at researching pills that can make people have children. Ao Xue has already said that she is willing to let me use the Heavenly Desire Pill. I'm a little excited," Ye Liuyun said excitedly.

When Lin Qingyou heard that Ye Liuyun wanted to try synthesizing this strange pill, she was very worried, feeling that something terrible was going to happen.

“The Pregnancy Fruit is a yellow-grade medicinal material, which you cannot use now. I suggest you use the Pregnancy Flower, which is a purple-grade medicinal material. You have been synthesizing for so long, you should have some experience in synthesizing pills. You can use the Pregnancy Flower as the main ingredient and then add appropriate auxiliary medicinal materials to refine the pill you want,” Lin Qingyou said.

This fertility flower is a medicinal herb that can increase the chances of male and female cultivators having children, but the chances are not high, and it is extremely expensive and rare.

Ye Liuyun only has three plants, but one is enough. Ye Liuyun has growth-promoting pills, so he can just find a medicinal field to plant an acre of them.

"Let's give it a try. It's my first time synthesizing a purple-grade pill. I'm so excited!" Ye Liuyun took out a peculiar medicinal herb. The herb was pure white, and its flower was shaped like an infant.

Ye Liuyun has two chances to synthesize the pill he wants.

"The main ingredient is the Pregnancy Flower, so we need to think carefully about the auxiliary ingredients." Ye Liuyun carefully examined all the medicinal materials he had stored, and then carefully analyzed their pharmacology. This synthesis pill is said to be random, but it is randomized within the range of the main ingredient. The general effects are similar, with only minor differences.

"I've got it! Let's try a combination of Pregnancy Flower, Heavenly Yang Root, and Profound Yin Flower first. After all, having a child requires the union of Yin and Yang." Ye Liuyun acted immediately.

She threw the three medicinal herbs into the Myriad Medicines Immortal Cauldron and then used the Myriad Medicines Immortal Fire to refine them. This time, using purple-grade medicinal herbs as the main ingredient to synthesize pills, Ye Liuyun felt a bit strained.

"This speed? It feels like it'll take some time," Ye Liuyun muttered to himself.

While Ye Liuyun was refining medicine, several people were stealthily sneaking towards him from near his residence.

They must have used some kind of stealth method; their sneaky behavior suggests they are up to no good.

They stopped at the foot of the mountain where Ye Liuyun's cave was located.

"Remember, our main task is to investigate Ye Liuyun's information and situation. Don't alert him," a woman solemnly reminded him.

As they walked, just as they were about to approach the bottom of Ye Liuyun's cave, someone seemed to have stepped on something.

With that step, a pair of scarlet eyes immediately lit up in the darkness.

"Huh? What is that?" The group of people froze, because something in front of them seemed to have been triggered by them.

One of them instinctively used his magic to ignite a flame. He glanced ahead and saw a black donkey standing on two legs, its body stronger than a stream of water, looking down at them.

No need to look anymore, they must have just stepped on the black bull and woken it up. This black bull seems to have some special ability; even though these people are invisible, it can still see them. Not to mention, some of them even actively released magical flames to illuminate the scene.

"What are you up to, sneaking around like this?" Black Bull, clutching the donkey's hoof, snorted heavily from his nostrils, glaring men in black with hostility.

"Damn it, there's a demonic donkey at the Nascent Soul stage guarding this place. How could there be any demonic beasts on Demon Peak? Could it be Ye Liuyun's pet? Run!" Without saying another word, the group tried to flee.

Now that we've been discovered, we can't continue. Before we're recognized, the best course of action is to flee.

The black bull, seeing these people of unknown origin turn and run away, immediately became unhappy.

"Sneaking around like this at night, are they trying to harm my boss? Since they're here, they're not leaving." Black Bull darted off and chased after the group.

With Black Bull's combat prowess, dealing with these weaklings in front of him was definitely a piece of cake. Black Bull moved swiftly, like a blur, and caught up with the strongest Dao Palace Nascent Soul cultivator in an instant.

Before the woman could even dodge, the black bull that had caught up with her hooves struck her on the head, knocking her unconscious.

As for the others, some have already taken to the skies.

"All of you, get down here." Black Bull opened his mouth wide and sucked at the group of people who had flown into the air, a powerful suction force pulling them back down from the sky.

And just like that, the group of people who came to gather information were easily dealt with by Black Bull.

He didn't disturb anyone else, keeping the whole process very quiet. After capturing and imprisoning these people, he removed the masks from their faces, revealing that they were several young female cultivators.

"What are you trying to do? We...we were just passing by, why are you attacking me?" The group began to feign ignorance.

Seeing that they weren't behaving themselves, Black Ox revealed a strange smile on his donkey face.

"Really? A misunderstanding? Let me warn you, don't think you're easy to fool just because I'm a donkey. And I'm a celestial donkey, not a demonic donkey. I'll give you a chance. Tell me what you're here for and who you are. If you don't tell me, hehe, I just happen to want to take in a few concubines. I think you guys are alright." Black Bull warned with a wicked tone.

These women are definitely not from any other faction; they should be from Medicine Peak. However, their cultivation levels are not high, so they probably just medicine apprentices.

"Hmph! Kill me if you want, why waste your breath?" These women are spies from the Reverse Immortal Alliance, hidden on the outskirts of Medicine Peak. They certainly won't tell the truth.

Black Bull was stunned, then reminded him again.

"You really won't tell? Fine then, you lot can prepare to have little donkeys for this immortal donkey."

After saying that, the black bull approached the group with a wicked look on his face.

Upon hearing that the strange donkey was going to do *that* to them, the women were so terrified that they fainted on the spot.

"Huh? This? You're such cowards! You can't even handle a little scare? Pshaw, don't worry, I'm only interested in female donkeys and mares. You humans aren't within my aesthetic range. I'll hand you over to the boss for interrogation tomorrow." After saying that, the black bull laid the men down on it like a cushion to prevent them from waking up and escaping.

An hour later, Ye Liuyun was finally about to fuse the pills.

"Ah, all done. Let's start fusing the pills." Ye Liuyun took a deep breath and directly fused the three medicinal herbs together.

At the moment the pills were fused, no particularly significant celestial phenomena occurred, except that a large amount of golden light floated out of Ye Liuyun's cauldron.

These glowing lights, like fireflies, pierced through the walls of the cave and spread to all parts of the Medicine Peak.

Ye Liuyun glanced at the glowing lights and continued synthesizing the pills; she couldn't afford to be distracted at this moment.

These fireflies seemed to have a sense of self; as soon as they drifted out, they quickly scattered in all directions. Several clusters of fireflies flew towards the women being pinned down by the black bull, and the fireflies directly entered their bodies.

It wasn't just them; the female apprentices living in the medicinal field area were also affected. The fluorescent light seemed to target female cultivators specifically, and it spread very quickly. In no time, it had permeated the entire Medicine Peak, and even the Peak Master, Tai Rong, was not spared.

"Huh? What's this feeling?" Nalan Yan, who was practicing making pills in her alchemy room, suddenly shuddered because a ball of firefly light had just entered her body.

However, since it was only a temporary discomfort, she quickly stopped paying attention to it.

The synthesis of these purple-grade medicinal herbs seems to be less efficient than the synthesis of the blue-grade medicinal herbs back then.

That's normal, though; not all elixirs cause a huge commotion.

As Ye Liuyun's pills took shape, the glowing light in the cauldron disappeared, and ten golden pills flew out of the cauldron, which Ye Liuyun grabbed in his hand.

"All done, Master. It seems there wasn't anything particularly big happening," Ye Liuyun asked quickly.

However, Lin Qingyou gave Ye Liuyun a strange smile.

"Yes, there probably won't be much of a commotion. You'll find out in a while. You should check out the effects of this pill first," Lin Qingyou reminded her.

Ye Liuyun nodded, then popped a pill into his mouth.

"Heavenly Dao Pregnancy Pill: It only works on female humans. After taking it, the user can conceive the child of the pill's creator."

Upon seeing this effect, Ye Liuyun immediately jumped up excitedly.

"Yay, Master, it worked! It worked on the first try! This was so easy! With this pill, Aoxue and I will definitely have a bunch of daughters!" Ye Liuyun said happily.

But as happy as he was, Ye Liuyun had a bad feeling, because many strange phenomena in the heavens and earth were related to the effects of pills, or even enhanced versions of the effects of pills.

"Huh? Master, what exactly was that thing that floated away just now? It wasn't anything too outrageous, was it?" Ye Liuyun stammered, asking somewhat fearfully.

She only wanted Lin Aoxue to have a child; as for others, she had no interest in that.

"What just flew out were infant spirits, which have nothing to do with you. But these infant spirits all came from the cycle of reincarnation. Your pill opened the reincarnation channel, and they all went to find hosts. Once this thing enters a woman's body, there is a chance that she will get pregnant," Lin Qingyou explained.

"Huh? It shouldn't have anything to do with me, right?" Ye Liuyun asked eagerly.

"Don't worry, this has nothing to do with you. Besides, the chances are very small, maybe only one percent. It depends on whether your female disciples on Medicine Peak are unlucky. Of course, you can't say they're unlucky. After female cultivators reach the Dao Palace realm, it's almost impossible for them to have children. If they get pregnant, it's just luck. Moreover, it's only their own bloodline and has nothing to do with anyone else," Lin Qingyou explained.

Upon hearing this, Ye Liuyun breathed a sigh of relief.

"In that case, I have done a good deed." Ye Liuyun smiled.

"That's hard to say. After all, not everyone is mentally prepared to be a mother. Besides, this is considered an abnormal birth, which will definitely cause them a lot of trouble," Lin Qingyou replied.

Ye Liuyun stopped worrying about it and quickly informed Lin Aoxue.

"Aoxue, Aoxue, I've successfully refined the pill. I made the pill I wanted on the first try. Are you mentally prepared? When do you plan to take it?" Ye Liuyun asked.

Lin Aoxue, who was meditating and cultivating at her residence, was also greatly surprised. She did not expect that Ye Liuyun had actually refined such a heaven-defying pill.

If this pill could be mass-produced, wouldn't it perfectly solve the problem of cultivators' infertility? This pill would be absolutely priceless.

"Don't rush, let's talk about it after this year's sect disciple recruitment event is over. I've been quite busy these past few days," Lin Aoxue said, suppressing her excitement.

This kind of thing definitely needs to be done at a suitable time.

“That’s true. But, Aoxue, I need to tell you something. My synthesized pills produced a large number of infant spirits. These infant spirits have just gone to find their hosts, which might cause the female disciples of Medicine Peak to become pregnant out of thin air,” Ye Liuyun said weakly.

Upon hearing this, Lin Aoxue paused for a moment, but her reaction didn't seem particularly strong; perhaps she didn't think it was a bad thing.

"Is that so? To be honest, for some female cultivators, this should be considered a blessing from heaven, but it's hard to say. Anyway, from my perspective, I'm definitely happy," Lin Aoxue said.

Ye Liuyun breathed a sigh of relief upon hearing Lin Aoxue's words. He then closed the communication channel with Lin Aoxue. Soon, a night passed, and Ye Liuyun was too excited to sleep.

The next morning, Ye Liuyun walked out of the cave early.

"Ah! Another beautiful day," Ye Liuyun exclaimed.

But just then, she heard the bellowing of a black bull.

"Big Sister, come here quickly."

Upon hearing the voice, Ye Liuyun quickly glanced down at a certain spot, then jumped down and landed steadily beside Black Bull.

But upon arriving, they discovered that several women in black, their bodies bound, were lying on Black Bull's side.

"What's going on? Did you arrest him?" Ye Liuyun asked, puzzled.

These women could only watch Ye Liuyun helplessly; they had no other options.

“Yes, those women sneaked up to your place last night, but they ran into me, so I took them in,” Black Bull replied.

Ye Liuyun thought for a moment, then had Hei Niu unmistakably open one of the women's mouths. Without saying a word, Ye Liuyun stuffed a Truth Pill into her mouth.

"Ugh! What did you feed me? A scholar can be killed but not humiliated. Now that you've captured us, we're just waiting to die." The woman glared angrily at Ye Liuyun.

Ye Liuyun rolled his eyes, and after a while, he asked...

"Who are you people, and what are you doing here?"

The woman originally wanted to say, "I'd rather die than tell you," but unfortunately, her mouth and brain betrayed her.

"We are peripheral disciples of the Reverse Immortal Alliance, and we are here on orders to investigate you," the woman said.

Alright, Ye Liuyun got the information he wanted.

"Oh, as expected of the Reverse Immortal Alliance, you guys are really fast." Ye Liuyun sighed.

"Damn it, what's wrong with me? Why am I telling the truth uncontrollably?" The woman's eyes showed a look of panic.

Ye Liuyun then asked a few more questions, but unfortunately, these people were just medicine apprentices from the Reverse Immortal Alliance who had infiltrated the Medicine Peak, and they were only peripheral disciples. They knew nothing about many things.

Ye Liuyun didn't intend to kill them. Instead, he gave each of them a Mind-Controlling Pill, which had a brainwashing effect and would make them under Ye Liuyun's control after they took it.

After they finished eating, their eyes immediately became blank.

"Go back. If your superiors ask, just answer truthfully," Ye Liuyun gestured.

Upon hearing this, the group immediately turned and left.

Ye Liuyun went to the herb field, where there are a hundred female herb apprentices. It's possible that some of them have been infected.

"Master, is there any way to tell if someone has been infected?" Ye Liuyun asked.

“Children conceived unnaturally do not lose their vital essence, so it cannot be seen from the outside. It will take at least a week to find out,” Lin Qingyou replied.

Ye Liuyun was somewhat uneasy, as if he had done something wrong.

Chapter 499 The Trouble-Making Neighbor (5000 words)

When Ye Liuyun arrived at the edge of the medicinal herb field, he found that the young apprentices had already started working. They were very punctual, just like ordinary people farming in the world.

Ordinary people simply work at sunrise and rest at sunset.

The same principle applies to planting medicinal herbs.

However, even if the spirit field wants the medicinal herbs to mature, it still takes time. Under normal circumstances, white-grade medicinal herbs can sprout in a day and reach the age of a hundred years in three months under the promotion of various fertilizers, while in the wild it generally takes at least three years.

This is the benefit of spirit fields: they draw spiritual energy from the earth's veins to nourish medicinal herbs. Green-grade herbs require at least three years of careful nurturing to reach the age of one hundred, while blue-grade herbs require thirty years. The higher the grade, the longer it takes.

Ye Liuyun couldn't wait that long, because the seeds he gave them were mostly green and blue grade.

Based on what she saw at the Taishang Ganying Sect market and Tianyi City last time, it seems that high-grade medicinal herbs are not grown in large quantities here.

“Strange, what kind of medicinal herb seeds did the young master give us? If they were white-grade medicinal herb seeds, they should have already sprouted, right? But after I watered them with spiritual liquid, there is no sign of sprouting at all.” Some of the apprentices had already noticed the situation in the spiritual field.
