The poison in Li Yun's poison sac is limited. Once it is squeezed out, it will take ten days and a half of rest to replenish it.

This old guy doesn't know how much snake venom he needs to use for research. If he is squeezed hard, it will be troublesome.

Li Yun thought to himself, "If this old guy dares to squeeze me hard, I will fight him to the death."

"Hey, Xiaohei, come on, come on."

At this time, the old man Mazi smiled maliciously at him and waved at him.

Li Yun rolled his eyes inwardly.

Bird, you are the weird one!

Immortal!

"You little thing, the old man called you over, but you still didn't give me face."

Seeing that Li Yun was motionless, old man Mazi rolled his eyes angrily, and then walked towards Li Yun.

Give you face?

How much is your face worth?

Li Yun thought to himself and prepared to run away.

Unexpectedly, as soon as this idea came up, the old man Mazi suddenly stretched out his hand to grab him.

The old man's hands were extremely fast, like a bolt of lightning, and he caught him in his hand instantly.

Li Yun was surprised.

This old immortal is very powerful, he is the sixth level of Extraordinary!

He couldn't escape just now.

After the old man Mazi caught Li Yun in his hand, he pointed at him and said with a smile: "You little thing, if you don't obey me, I have to let my old man take action."

With that said, he led Li Yun to a table where poisons were studied.

There were many bottles and jars on the table, which were rather messy, as well as the ancient book that recorded poisons that Li Yun had seen before.

The old man Mazi sat at the table, and then took a small empty jar from the side.

He put the empty jar under Li Yun's mouth and said with a smile: "Xiao Hei, be good and spit out the poison in your body."

Li Yun rolled his eyes, naturally he didn't offend him.

"If you don't behave, you will force my old man to take action."

Seeing that Li Yun ignored him, the old man Mazi said: "If my old man takes action, you will suffer the consequences. Don't blame me then."

Li Yun really couldn't listen to this.

Old Man Mazi is a strong man of extraordinary sixth level.

There are really many ways to force him to spit out the poison in his body.

Once Old Man Zi does this, Li Yun will definitely suffer some punishment.

After weighing the pros and cons in his mind, Li Yun still spit out some poison.

Rather than being forced to vomit poison by a pockmarked old man, it is better to spit out the poison yourself and avoid suffering the consequences.

Drops of dark venom were seen flowing out from Li Yun's two long teeth and dripping into the jar.

After about ten drops, Li Yun shut up and stopped vomiting.

"Xiao Hei, spit some more, spit some more."

The old man Mazi was dissatisfied and urged him to spit out more poison.

Li Yun had no choice but to spit out another ten drops of venom.

No matter what old man Mazi said this time, he would no longer vomit poison.

Fortunately, the old man Mazi didn't force him too much. He put him aside and told him not to move around, and then he lowered his head to study the snake venom.

When the old man Mazi was doing research, he was very focused and selfless.

I saw him tinkering around with various poisonous weeds and poisons, and flipping through the ancient book from time to time.

Li Yun was a little curious and wanted to see what kind of poison he was researching.

So, take a closer look.

After a quick look, he discovered that the poison that Old Man Mazi was researching now was actually the poison he had memorized last time.

To be honest, although I know how to refine this poison, it is quite difficult to refine it.

Li Yun was still worried about how to refine it for future use.

Now I see old man Mazi refining this poison.

He couldn't help but look at it intently.

If he had seen Old Man Zi successfully refining the poison, it would undoubtedly be much easier for him to refining the poison himself in the future.

Li Yun watched intently.

Old Man Mazi refined the snake venom from morning to afternoon. He used up the snake venom in the middle and asked Li Yun to spit out some venom.

Li Yun actually cooperated with him and spit out some venom.

At almost five o'clock in the afternoon, Old Man Mazi refined it dozens of times, and finally succeeded the last time.

"Haha, the emperor has paid off his hard work. Old man, I finally refined it."

I saw old man Mazi holding a small medicine bottle, standing up and laughing, his beard trembling, obviously very happy.

Next to him, Li Yun also let out a breath.

After reading it, he realized that the difficulty of refining this poison was beyond his imagination.

I thought that Old Man Zi could easily refine it, but I didn't expect that it took him so many times to refine it.

Fortunately, I came to see it today, otherwise I wouldn't know if I could make it if I had to make it myself.

Li Yun thought to himself.

The situation is different now. It would be many times easier for him to refine this poison.

Because how did Old Mazi fail to refine it just now, and how did he succeed in refining it.

Li Yun saw it clearly.

He has already kept these in mind.

If he really took matters into his own hands, he was sure that he could refine this poison.

At this moment, the old man Mazi put the refined poison on the shelf, then turned to look at Li Yun and said with a smile: "Little guy, you have worked hard today, old man, I will not take advantage of you in vain.

.”

Having said this, he took out a green plant and threw it to Li Yun.

"If you hold this thing, it should be of some benefit to you."

Li Yun opened his mouth and bit the plant in his mouth.

He had already seen that this was a spiritual grass.

Although I don’t know what level this spiritual grass is, it is definitely good stuff.

This old guy still has some conscience.

Li Yun narrowed his eyes and smiled, then swallowed the spiritual grass bit by bit into his belly.

"Ding! You took an intermediate spiritual grass, and your evolution points +1000."

Intermediate spiritual grass, not bad.

Li Yun smiled.

Although I gave old man Mazi a lot of venom today, with this intermediate spiritual grass, everything was worth it.

After all, there are 1000 evolution points.

"Okay, you've got the benefits, now it's time to send you back."

The pockmarked old man narrowed his eyes and looked at Li Yun, then grabbed him and walked out.

Came to Yang Yun'er's home.

Yang Yun'er had just finished lunch and was playing with the little fox and little turtle on the sofa.

Seeing old man Mazi coming in, Yang Yun'er stood up and said with a smile: "Grandpa Jiu, you are willing to give Xiao Hei back to me."

"What? Little girl, are you still afraid that the old man won't return Xiao Hei to you?"

The pockmarked old man said with a smile.

"No way, I know Grandpa Jiu that you wouldn't do this."

Yang Yuner said with a smile.

"Ha ha."

The old man Mazi laughed loudly, handed Li Yun back to Yang Yun'er, then turned and left.

After the old man Mazi left, Yang Yun'er looked at Li Yun and said, "Xiao Hei, are you okay? What did grandpa ask you to do?"

Li Yun just looked at her with his eyes and naturally said nothing.

"Hehe, I forgot that you can't speak."
