Oh no! I, the weakling, have become the villain!

Upon hearing this, the group turned back.

Seeing the herbs these people were carrying, Xu Yao felt a surge of anger rising within him.

What is this thing?

It's not that none of them were the right ones, but rather that they were completely unrelated!

Looking at the herbs, Xu Yao took a deep breath, raised his hand and gently pinched the bridge of his nose, forcibly suppressing the anger in his heart.

"I'll put everything else aside for now, but what's the point of you bringing a whole bunch of these? Are you kidding me?"

After saying that, Xu Yao turned to look at Hei San. Before Xu Yao could speak, Hei San walked over and took out four kinds of herbs.

The four herbs Qingfengcao, Biluohua, Xuefengcao, and Zanghongcao are all quite good.

Xu Yao raised an eyebrow at Hei San, his face showing some surprise.

He's even starting to suspect that the Blood Demon might be selecting people based solely on their suitability for alchemy, as seen with Chengfeng and Hei San.

However, the soldiers under his command are really incompetent.

Xu Yao nodded as he looked at the four herbs, then turned to look at the other members of the Blood Demon Hall.

"All correct, did you see that?"

Upon hearing this, all the Blood Demon Hall members lowered their heads, their faces full of embarrassment.

Hei San glanced at these people with a hint of disappointment. There were only four types, not forty, and they couldn't even remember them.

Xu Yao turned to look at Hei San and said, "These people are in your hands. Call me back when they can identify these four herbs."

After saying that, he turned to look at Chen Feng. Chen Feng understood, stood up, and walked out with Xu Yao.

Surprisingly, Hei San did not stop them, but instead let them leave.

Xu Yao didn't go back until the afternoon.

However, he seemed to have underestimated the stupidity of these people. When he arrived, only a small number of them had picked up the correct herbs, while the rest had picked up herbs that were similar but had different effects.

Not to mention Xu Yao, even Hei San wants to make a move this time.

He's been teaching here for almost a day, and so many people are still making mistakes.

Isn't this a blatant slap in his face?

Xu Yao turned to look at Hei San and said helplessly, "Keep those who got it all right, and take the rest back first."

Hei San turned to look at the people with their heads down and said sternly, "Didn't you hear me? What are you still doing here? Get out of here right now!"

These people immediately left, not daring to stay there any longer.

Xu Yao then introduced them to some herbs, and while they were searching for them, Xu Yao turned to look at Hei San.

"To refine pills, you must first learn about herbs. They don't even have the basics, so I can't teach them. Go tell Blood Demon to bring back some complete herbal encyclopedias."

This time, Hei San didn't object and nodded in agreement.

Judging by the timing, it's about time to head to the ghost market tomorrow.

Xu Yao was worried that Blood Demon had forgotten, so he mentioned it to Hei San.

After preparing everything, Xu Yao had Hei San watch over things here, then turned around and left, returning directly to the secret room in the prison.

When he went in, Chengfeng was still refining pills, but the condition of these people was much better than before.

He should wake up in about a week.

Xu Yao now has to start thinking of ways to make sure they have more time to wake up.

They left only after confirming that there were no problems.

To Xu Yao's surprise, Hei San actually led a group of people up the mountain to collect medicinal herbs.

There's a Qi Yue Mountain straight ahead behind the Blood Demon Hall. It's not very close; it takes at least two hours to go there and back.

Is Black Three planning to stay on the mountain all night?

Anyway, it had nothing to do with him, so Xu Yao didn't think too much about it.

However, they stopped messing around with Hei San. At least compared to Hei Da, Hei San was still cute.

If Hei San leaves and Hei Da comes in, he'll probably be really depressed.

The next day, as soon as Xu Yao arrived, these people were already waiting there, and Chen Feng was sitting in front of him drinking tea and waiting for Xu Yao.

However, these people were very dirty, and their sleeves looked like they had been torn. Among them, only Hei San was in slightly better condition.

In front of them was a basket full of herbs, but the yield was very small, and some of them were just weeds.

However, for those who don't understand herbs, this is already quite good.

Xu Yao turned to look at Hei San and said, "Where are the items? The problem of the complete herbal compendium hasn't been resolved yet?"

"No, the black box will be delivered soon."

Hearing the name 'Hei Da' gives me a headache.

He went over to the medicine shelf next to him, took some herbs, and began to refine elixirs.

Before he could even begin, Hei Da walked in with a dark expression and ordered the herbal compendium to be distributed.

Seeing that Hei Da was still there, Xu Yao frowned and said impatiently, "Why aren't you leaving? What, do you want to teach them a lesson?"

Hearing this, Hei Da's face darkened even more. He snorted coldly and turned to leave.

Sensing a fierce aura, Xu Yao turned his head and saw Hei San staring at him with anger on his face, as if he wanted to devour him.

Xu Yao didn't mind, turned to the others and said, "You should first learn about the herbs in this book. I will check them this afternoon."

After saying that, he threw all the herbs on the table onto the alchemy plant and then began to refine pills by controlling the fire.

Seeing Xu Yao's actions, no one else had the mind to look at him anymore; all eyes were on Xu Yao.

His face was full of admiration and envy.

Half an hour later, with a 'hum', Xu Yao opened the alchemy furnace, and the entire room was enveloped in a layer of red mist, which was very dreamlike and a scene that none of them had ever seen before.

Xu Yao packed up all the pills, and only then did the mist disappear.

Before he could even turn his head, he saw these people staring straight at him, staring at the pills in his hand.

Hei San frowned and asked somewhat awkwardly, "What kind of pill is this? What was that mist just now?"

Xu Yao looked at the pill in his hand, feeling a little heartbroken, but still tossed it directly to Hei San.

"Spirit Enhancement Pills can strengthen the spiritual power within the body, especially when spiritual power is depleted during battle. There are eight pills in total. I'm entrusting them to you for safekeeping. You can reward whoever performs well."

Hearing these words, everyone became excited.

If one's spiritual energy is depleted during a battle, it could be fatal. However, if one has a Spirit Enhancement Pill, it's like having half a life.

The Spirit Enhancement Pill is worth at least five thousand taels on the market, which they simply cannot afford. Now Xu Yao is giving it away like this?

Upon hearing this, everyone stood up, cupped their hands in gratitude to Xu Yao, and looked at him with deep appreciation.

"Thank you, Master Xu!"

Xu Yao chuckled twice without saying a word, then turned and walked to the medicine shelf next to him, taking out some herbs to start refining pills.

Xu Yao spent the entire morning setting up the furnace, refining pills, and retrieving the pills.

It wasn't until the afternoon that Xu Yao began refining other pills.

However, since I promised to give Chongfeng two Foundation Establishment Pills and only asked for the money for one, this guy shouldn't be short of Foundation Establishment Pills now, right?

Moreover, he was going there this time to bring him big news.
