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

This old thing doesn't know how much snake venom to use for research, and if he is crushed hard, it will be troublesome.

Li Yun thought to himself, "If this old thing dares to squeeze me hard, Lao Tzu will fight with him." ”

"Hey, little black, come, come here. ”

At this time, the old man smiled at him maliciously and beckoned to him.

Li Yun rolled his eyes in his heart.

Birds, you're weird!

Old and immortal!

"You little thing, the old man called you over, and you didn't even give me face. ”

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

Giving you face?

How much is your face worth?

Li Yun thought in his heart, and prepared to slip away.

As soon as this idea came to him, the old man suddenly stretched out his hand and grabbed him.

The old man's hand was extremely fast, like a bolt of lightning, and he caught him in his hand in an instant.

Li Yun was surprised.

This old immortal's strength is very strong, it is an extraordinary sixth order!

He couldn't dodge the past just now.

After the old man Mazi grabbed Li Yun in his hand, he pointed at him and smiled: "You little thing, you are disobedient, you have to let my old man make a move." ”

As he spoke, 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 Li Yun had seen before, which recorded poisons.

The old man sat down at the table, and then brought 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, spit out the poison in your body." ”

Li Yun rolled his eyes, naturally there was no bird for him.

"If you don't, you're forcing my old man to make a move. ”

Seeing that Li Yun ignored himself, the old man Mazi said: "If my old man makes a move, you will be guilty, and you won't blame me then." ”

Li Yun really can't listen to this.

The old man Mazi is a powerhouse of the extraordinary sixth order.

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

Once the old man does this, Li Yun will definitely suffer some living crimes.

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

Yu Qi was forced to vomit poison by the old man Mazi, it is better to spit out the poison himself, and he doesn't have to suffer that crime.

I saw drops of pitch-black venom flowing out of Li Yun's two long teeth and dripping into the jar.

After dropping more than ten drops, Li Yun shut up and stopped spitting.

"Xiao Hei, spit it out a little more, spit it out a little more. ”

The old man Mazi was not satisfied, and urged him to spit out some more poison on the side.

Li Yun had no choice but to spit out more than a dozen drops of venom.

No matter what the old man said this time, he stopped spitting poison.

Fortunately, the old man Mazi didn't force him too much, put him next to him, and asked him not to move there, so he took the snake venom and bowed his head to do research.

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

I saw him holding all kinds of poisonous weeds and venom to pound there, and he also flipped through the ancient book from time to time.

Li Yun was a little curious, wanting to see what poison he was working on.

So, take a closer look.

At a glance, he realized that the poison that the old man was studying now turned out to be the kind of poison he wrote down last time.

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

Li Yun was still worried about how to refine it so that it could be used later.

Now I see the old man Mazi refining this poison.

He couldn't help but look intently.

If he had seen the old man Mazi refine successfully, it would undoubtedly be much easier for him to refine this poison himself in the future.

Li Yun watched intently.

The old man Mazi refined from morning to afternoon, used up the snake venom halfway, and asked Li Yun to spit out some poison.

Li Yun cooperated with him very well and spit out some venom.

When it was almost five o'clock in the afternoon, the old man Mazi refined it dozens of times, and the last one finally succeeded.

"Haha, the emperor has lived up to his hard work, old man, I finally refined it. ”

I saw the 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 the old man Mazi could be easily refined, but he didn't expect that he would use it so many times to refine it.

Fortunately, I came to see it today, otherwise I don't know if I can refine it by myself.

Li Yun thought to himself.

Now the situation is different, if he starts refining this poison, it will be many times easier.

Because just now, how did the old man fail to refine it, but how he succeeded in refining it.

Li Yun saw it clearly.

He had already taken it to heart.

If he really did it himself, he was sure that he would be able to refine this poison.

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

Speaking of this, he took out a turquoise vegetation and threw it to Li Yun.

"You hold this thing, it should be a little good for you. ”

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

He had already seen that this was a spirit grass.

Although I don't know what level this spirit grass is, it's definitely a good thing.

This old thing has a bit of a conscience.

Li Yun squinted and smiled, and then swallowed the spirit grass into his stomach little by little.

"Ding! You have taken an intermediate spirit grass, and your evolution point is +1000. ”

Intermediate spirit grass, not bad.

Li Yun smiled.

Although he gave the old man a lot of venom today, with this intermediate spirit grass, everything was worth it.

After all, 1,000 evolution points.

"Alright, you've got the benefits, it's time to send you back. ”

The old man squinted at Li Yun, and then grabbed him and walked out.

came to Yang Yun'er's house.

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

Seeing the old man Mazi come in, Yang Yun'er stood up and said with a smile: "Ninth Grandpa, you are willing to return Xiao Hei to me." ”

"What's the matter, little girl, are you still afraid that the old man won't give you back Xiao Hei?"

The old man said with a smile.

"What's the matter, I know Grandpa Nine, you won't do this. ”

Yang Yun'er said with a smile.

"Haha. ”

The old man laughed, returned Li Yun to Yang Yun'er, and then turned around 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 tell you to do?"

Li Yun just looked at her with his eyes, and naturally did not speak.

"Hee-hee, forget you can't speak. ”

Yang Yun'er grinned and put Li Yun down.
