As Lao Liu Zi spoke, the skinny old palm swiped on his storage ring, and a few bottles of green liquid appeared, handing them to Cao Yu.

"This is the liquid used to corrode those cold iron chains, and that's all the old man has in his hands!"

Now for Lao Liuzi, the things on his body are completely useless, after all, if he enters the loess, how much money and how many treasures will be floating clouds.

If you don't bring it in life, you won't bring it in death!

What is left is his kindest and most simple quality, Cao Yu thought in his heart, he must Lu Liang spread the spirit of Lao Liuzi.

It is not easy to have this kind heart in this world of the jungle!

"Old Liu, I thank you for them!"

Liu Zhi knew very well the difficulty of those cold iron chains, and he naturally knew that Lu Qing was rescued by them, and now he was willing to take out these corrosive liquids, which was really the prime minister's belly to support the boat.

After all, to be honest, Lao Liu Zi actually didn't have much to do with him as long as he saved Lu Qing.

If he can help, that's kind to him.

"That's all the old man can do!"

At this moment, Cao Yu had clearly felt that no matter how much he input his true yuan, it was useless, and it was no longer absorbed by Lao Liuzi's body, but emitted out of his body on his own after walking around.

After saying that, Lao Liu Zi closed his eyes with satisfaction.

He walked peacefully!

The people present did not speak, the old drunkard also stopped sobbing, and everyone consciously bowed to the old Liu Zi three times.

"Elder Liu is a role model for my generation, and deserves to be praised by the world, and the discovery here today is the credit of both him and the non-elders, who saved those hundreds of young girls, and I propose to bow three times again as a sign of respect."

After Cao Yu finished speaking, he bowed first, and of course the rest of the people had no objections, and they all bowed consciously.

Rumors circulating on this continent.

Man is inherently dead, or heavier than Mount Tai, or lighter than a feather!

Today!

This old man's self-denial!

It is really heavier than Mount Tai, and it is their discovery that has saved nearly a thousand girls from the sea of suffering.

Otherwise, even if Cao Yu destroyed the Pan family, those people might never see the light of day.

This day should be remembered!

"You guys bring Elder Liu and non-elders back first, leave the matter here to me, and please help pass the word to President Lu, Elder Liu must be buried thickly, just say that it was said by Cao Yu of the Heaven Killing Sect!"

He is a scholar in white at the moment, of course he can't say himself, but as long as he hears Cao Yu, then Lu Liang will definitely handle this matter properly.

"Yes, sir!"

Several Danta alchemists standing on the side responded with their fists in their fists, beckoned people, and took the body of Lao Liu Zi and Fei Chang, and Lu Qing left quickly.

"Let's go, let's see what's going on."

Cao Yu beckoned and led the rest of the people to the entrance of the underground space.

When Cao Yu saw the situation below, his surprise was no weaker than that of the others, and at this moment he felt that it was an extremely wise decision to destroy the Pan family.

Not only is it not a sin, but it is still a great merit.

How sad it is to think that these girls are in their best years, and they don't even have the hope of dying!

"My lord, those cold iron chains are extremely difficult to entangle, Elder Liu's corrosive liquid should be effective"

Liu Zhi looked at Cao Yu with some expectation, of course, hoping that he would save his daughter first.

"Where?"

The old drunkard Liu Zhi immediately specified the direction, and Cao Yu quickly took out those green liquids.

When I uncorked the bottle, an extremely pungent smell permeated, and it was obvious that it was somewhat toxic.

"This... Elder Liu can't be wrong!"

Liu Zhi was concerned about the chaos, seeing that this was obviously like a poison, how could it corrode the cold iron chain.

"That's right, this liquid is extremely corrosive, you get out of the way and leave it to me!"

Cao Yu didn't start immediately, but flipped over his hand, took out an extremely strong pill, and transported the true yuan in his hand to the extremely weak woman on the stone pillar.

With the effect of Zhenyuan, the pill was melted, and in a blink of an eye, I saw that the face of the loli-type girl in front of me had improved a little.

Liu Zhi was very happy when he saw this scene, he actually wanted to take the pill to treat his dream first, but he was not stunned, he knew that this kind of person who had been oppressed for a long time, if he suddenly had a big supplement or used an inappropriate pill, he might directly let people hang up.

Of course, he is very relieved about Cao Yu, but judging from Cao Yu's methods and consciousness, it is obvious that he understands a little bit of medical skills.

"My lord, such a great kindness, thank you for the little girl!"

As the old drunkard spoke, he knelt down with a thud, and his eyes were filled with unconscious tears.

He sheds more tears today than he did decades before.

Whether it is the joy of the reunion of father and daughter, or the sadness of seeing his daughter in such a tragic state, or Cao Yu's rescue without paying.

Everything touched his heartstrings greatly!

"With a gesture, you don't have to be like this, Elder Liu!"

Cao Yu waved his hand, signaling Liu Zhi not to kneel anymore, and then began to corrode the cold iron chain.

Now that we know that this corrosive liquid is toxic, the protective measures for the girl must naturally be in place, otherwise, the person may hang up before he is saved.

Every girl here is skinny, skinny, and extremely heart-wrenching to watch.

Cao Yu directly relied on the vigor and domineering of his true yuan, simply wrapped the corrosive liquid, and slowly penetrated into the cold iron chain, as soon as he touched the cold iron chain, as predicted, the cold iron chain that the rest of the people had to cut off was like foam, making a snorting sound, and it directly corroded the iron chain in less than three breaths.

This method can save a lot compared to Lao Liuzi's before, after all, he can use it again on the rest of the girls if he doesn't consume it.

"Dangchang!"

The chain fell to the ground, and the girl was about to fall, but the old drunkard immediately rushed over and helped the girl.

That is, his daughter, Liu Menghan!

Looking at the deep traces on Liu Menghan's body that have been strangled by iron chains for many years, he was directly deformed along with the bones.

The old drunkard's heart was like a knife cut, hugging his daughter as light as tissue paper, and his whole body was trembling!

No matter how hard-hearted the old father is, he can't stand it when he sees his daughter like this.

At this moment, he is in no mood to care about other people for the time being, which is understandable, his daughter must be taken care of like this.

Cao Yu solved the iron chain on Liu Menghan's body and continued to the next one, and every time before starting, he would stuff a pill in the mouths of those girls, but the grade was obviously not as high as Liu Menghan's.

This scene was seen by everyone.

I was very curious in my heart, Cao Yu knew very well how much he hated the Pan family, but now he was very merciful to these strange girls.

It's a bit unpredictable!

At first, they all thought that Cao Yu was a cold-blooded big devil.

But judging from the latter things, the actual situation seems to be somewhat different.

There are the original guards of the Pan family who helped at the scene, but these are all disdainful of the Pan family, and the wrong ones, those who lick the dogs have long been killed!

And then there's some offerings!

In fact, most of these people are forced to make a living.

Therefore, there are no longer a few people who are angry with the Pan family on weekdays.

Less than a hundred people were rescued, and a thorny problem arose.

Not enough corrosive fluid!

In fact, Cao Yu considered this problem after rescuing the previous few people, because the corrosive liquid could corrode several cold iron chains, so he began to think of a way at that time.

He also tried to try the weapon to cut a few times, but the effect was the same, there was nothing special, no accident, no matter how big he was, the weapon in his hand couldn't withstand it.

There's only one way to think about it!

Refine your own corrosive fluid!

This is the best way he has come up with at the moment, after all, he is an alchemist himself, and there are other alchemists present, so he can let them together, which is more efficient!

However, the formula of this corrosive liquid has become a big problem, and those alchemists who asked Danta are all like rattles, they don't know this formula at all, let alone the formula, they have never even seen this thing, how can they say the formula.

The other one is medicinal herbs!

For a time, there was an impasse.

It is impossible to give up the treatment of these people! This is the basic public morality of a monk.

"My lord, why don't we go back and ask the president if there is a recipe for this kind of corrosive liquid?"

A young alchemist stepped forward and proposed.

At the moment, he can only be a dead horse as a live horse doctor, there is no formula, Cao Yu is also a clever woman who is difficult to cook for drinking rice, nodding and agreeing, let them go and come back quickly, and let Lu Liang arrange more people to come in.

Before leaving, the people were given several formations and informed of the route.

Because now the entire Pan family is still in the big array he arranged, in the eyes of people outside, the Pan family is still calm.

The wave of people who walked in front naturally had arrangements, but it would not be impossible to get out.

"Yes, sir!"

Now that the corrosive fluid has run out, they can only stare dryly.

But Cao Yu commanded, let them do their best to deliver true yuan to those weak girls who have been rescued, at least they can do more.

He himself began to think about it in his head!

That's right! Chaos Library!

Cao Yu was so busy that he neglected that he still had the god-level plug-in of the Chaos Library, but he didn't know if he could analyze something useful based on these corrosive fluids.

I found a little sample from the previous corrosive fluid, and began to analyze it in my mind using the Soul Broken Library.

"Tick! to start analyzing, please wait a moment... ”

The Mixed Library made an icy mechanical sound, and after receiving Cao Yu's order, the analysis process began.

This time, I don't know if it is the reason for the rarity of this corrosive liquid, the analysis time is long, but the root cause is estimated to be insufficient knowledge absorption.

For this supercomputer-like existence, as long as there is enough data, he can analyze something extremely unheavenly, but this is only Cao Yu's own estimate.

"Analysis Results: The Wu Clan's Erosive Liquid, which is specially used by the Ancient Wu Clan in combat, has extremely strong corrosive properties, and the rest of the effects..."

Cao Yu finished reading all the information with his eyes, but there was no formula, which made him so anxious!

"Can you get the recipe for this elusive liquid?"

The Chaos Library once again raised its own questions in his mind.
