"Hey, what are you doing here, do you have something to go out?"

Liu Zhi also looked at Cao Yu with an embarrassed face and said, "It's okay, it's okay, let's breathe, breathe!"

"Yes, yes, breathable!"

Of course, they can't say that they are afraid that Cao Yu will blow up the furnace again, although they don't know how Cao Yu extinguished the Dan furnace that was going to be fried last time.

But who knows if it will be fryer next time, and if it is necessary, it is still a big question whether the fryer can extinguish the Dan furnace again.

So at the moment, they are thinking about a way back for themselves.

Okay, it's up to you!

Of course, Cao Yu knew what these people thought, but he didn't break it, and cleaned the Dan furnace with his hands and feet, preparing for the next refining.

The last failure had already eliminated the ghost bamboo, so the other Hundred Refining Fruit must be the medicinal materials among them.

Combined with his previous reasoning, the two that could not be determined in the end were the Tears of Frost and the Ice Spirit Liquid.

But in fact, he already has a choice in his heart, that is, the tears of cold fire, he believes in his reasoning and feelings, it stands to reason that there should be no mistake nine times out of ten, and even if he is wrong, it is not a big problem.

With the origin space to fight fires, he no longer has to be afraid of the crisis of the explosive furnace.

After cleaning the Dan furnace and preheating it again, it was still in the style of a big pot stew, and when they saw this operation, everyone was still scrambling to move slowly up the steps.

But no one left right away, they were all watching the situation unfold.

Cao Yu is still indifferently melting those medicinal materials, this time it can be said that he is confident, and at the moment he is thinking about how to teach the refining method to the rest of the alchemists, after all, he is alone, the refining speed is still relatively slow, and those girls who are on the verge of death can't hold it for long.

Time is of the essence!

This is not wrong at all, Cao Yu also deeply felt the burden on his shoulders, although these people have nothing to do with him, and can even be said to have nothing to do with them, but at the moment, only he has the ability to save them, if he leaves, even he will be uneasy!

This is a unique good quality formed by the thousands of years of culture of the great Chinese country on the earth in the previous life, and the deep-rooted ideas will basically not change!

There is still no problem in the refining stage of the liquid medicine, and then there is the stage of fusion, the previous fusions have been familiarized, and when choosing the Hundred Refining Fruit, there is no hesitation, because it was selected before the input, but the order of fusion has changed.

The ending was as expected, the multi-faceted fusion ability of the Hundred Refining Fruit perfectly eased the pharmacology, and the last medicinal material, the Tears of Cold Flame, the last refining was actually chosen as this, but Cao Yu knew very well at the root that it was the problem of the ghost bamboo.

When all the medicinal liquids were fused together, the Dan furnace became fiery red again!

This situation is almost the same as the first time, the old drunkard and those people immediately pulled out their legs and ran out, ignoring Cao Yu at all, but they were not without a bottom line, at least they took all the girls who had been rescued out together.

Cao Yu looked at the Dan furnace in front of him calmly, in fact, the reaction inside was very violent, and he knew very well, but these were all expected situations, this was the last process of the finished liquid medicine, which was equivalent to removing the impurities after fusion again.

After half a full incense stick, the temperature in the Dan furnace finally slowly dropped, and a smile appeared on Cao Yu's face.

He knew that this time it had been successful!

He just didn't know what the effect was, and he also had to think about how to get the rest of the alchemists to refine it together.

Of course, this method he used was not suitable for the rest of the alchemists, although the refining speed of their medicinal materials would be much slower, but it was better than refining it alone!

took out a porcelain bottle in his hand, and now he only has a pill on his body, which is much worse than the porcelain bottle that specializes in storing medicinal liquids, but he is not for storage, but for temporary placement, and the things that are about to be used up have little impact.

"Hey, I made it, you guys came down to save people!"

Cao Yu shouted towards the entrance at the top of his voice.

The people who heard the sound poked their heads down, and saw that there was no hot feeling, and at the same time saw Cao Yu holding a green bottle in his hand, it was obvious that it was indeed a success!

It's just that the effect is yet to be tested!

"Master Yu, you are really amazing, without further ado, let's hurry up and save people!"

Previously, Cao Yu called himself Yu Wenwei, so they only knew Cao Yu's name.

Liu Zhi jumped down first, there was no embarrassment on his face, he actually wanted to transfer his daughter out first, there was really nothing wrong with it!

"Let's try it first! If you can, you will need to refine a few more copies, but there are still hundreds of people to be treated on the scene, this is a huge project, and the rest of the alchemists need to help too!"

Fixedly looking at the corrosive liquid in his hand, Cao Yu is looking forward to the effect of this thing, after all, it is not only necessary to save these girls, but also to use it in the future when he fights, if the effect is too mediocre, it is estimated that it will have no effect, and it will be a waste of energy!

"That's right, let's try it! Judging from the quality, I'm afraid this won't be worse than the effect given by Elder Liu!"

"Hopefully!"

Indeed, as Liu Zhi said, judging from the depth of the color and the poisonous gas wafting out, the effect should not be too bad, after all, Lao Liuzi's bottle has been stored for a long time, and the natural medicinal effect will lose a lot.

He had treated nearly a hundred young girls before, and he was already familiar with corrosive cold chains.

Pour out some and wrap it in golden true yuan, everyone is actually very curious about Cao Yu's true yuan, but they are used to Cao Yu's rebellion, it seems that all the abnormal situations in Cao Yu's body have become normal, if Cao Yu's performance is too mediocre, it will make them feel abnormal.

The psychological role of human beings is so strange!

"Snort!"

In less than a breath, the cold iron chain larger than an adult's thumb was instantly corroded, and when there was a bang, the iron chain fell to the ground, and someone immediately stepped forward to support the girl.

Seeing this result, Cao Yu's face looked slightly better, but he didn't live up to his hard work, not only spent a lot of money to restore the Chaos Source Bead again, then analyzed the formula, looked for medicinal materials, and almost fried the furnace.

These operations seem to be not difficult for Cao Yu to do, but they can be extremely difficult for others!

The formula is the most difficult, and at the same time, although the medicinal materials are not very common, the number of requirements is also quite a lot, and the preparation of the entire medicinal liquid requires nearly two hundred kinds of medicinal materials, fortunately, they are cultivators, and they are very fast to do these things, otherwise, it will be estimated that it will take ten days and half a month to prepare these things alone.

At the same time, the amount needed is not small, at this moment, Cao Yu is very glad that he went to loot the treasure house of the Pan family first, otherwise he can only stare dryly, if they wait for them to go back to raise medicinal materials, then several people will have to die.

"Lord Yu, it's really effective! It's several times more effective than the previous bottle!"

Everyone saw that this newly refined corrosive fluid worked very well!

"And it doesn't seem to corrode a chain, and it takes a lot less corrosive fluid, have you noticed?"

One of them was observant, prompted.

"Well, that's right! At this dose, this bottle of liquid medicine I refined can corrode the cold iron chains of two people!"

Cao Yu, as a person who personally operates the actual operation, is naturally the most aware of this effect.

"U-sama, you are so amazing! I adore you so much!"

The alchemists of those Danta had an incomparable fanaticism in their eyes, and for this kind of ability that they could analyze the pills and formulas by looking at the pills or medicinal liquids, it was indeed the ability that these low-level alchemists dreamed of.

But this thing is not enviable, personal talent!

"Calm down!

Cao Yu waved his hand, and then said to those alchemists: "Now that the opportunity has come, I will give you the recipe and medicinal materials, and you can also come and refine them together!

As soon as these words came out, all the alchemists were eager to try, and at the same time, the gaze that looked at Cao Yu became more respectful again.

Normally, if an ordinary alchemist develops a formula for a pill or liquid medicine by himself, they will never directly take it out for others to refine and watch.

Because there is a patent issue involved, after all, the first person to eat crabs must be the first to know the taste.

Generally speaking, in this case, they will choose to join forces with this kind of Danfang with a big force like Danta, or all the rest of the alliances and super sects, and after it is launched, everyone who wants to use this Danfang needs to pay a certain amount of spirit stones, which is regarded as a patent fee.

If it is not indicated by the big forces, then someone else can usurp the patent.

So they saw that Cao Yu actually disclosed the newly developed liquid medicine formula to them, and this kind of open-mindedness made them deeply admire.

Is this the difference between people?

Cao Yu naturally doesn't know so many doorways, and at the same time, he doesn't have so much energy to participate in these trivial things, as long as he wants to, he can come up with these pills and formulas, but it is really of little use to him, and the most important thing is to improve his strength.

If the strength is not good, even if you have more resources and treasures on your body, it will only make you more dangerous, and there will be jackals, tigers and leopards staring at you all the time.

Strength, the eternal truth!

This is a philosophy that Cao Yu has deeply realized again and again since he came to this world.

"Thank you, Lord Yu, you are really magnanimous, we are fortunate to be able to refine it, it is a blessing in exchange for immeasurable merits in the previous life!"

They are really first-class, and they say one thing at a time.

Cao Yu was even a little bored, although it sounded more comfortable, but he was tired of it.

"Don't talk nonsense, let's get ready to start, you take a look at the formula first, if there are questions to ask one by one, the number of medicinal materials is not much, you can't waste it!"

Because of the special corrosive liquid, Cao Yu can only save them one by one, otherwise it will not be good to hurt those girls.

Cao Yu burned the recipe into a jade slip and didn't let them read it one by one before returning it to him.

Those alchemists pondered after reading it, the first time they saw such a perfect fusion, they simply brought out all the medicinal properties.

The admiration for Cao Yu in my heart has once again been raised to a peak!
