Zhang Lifeng took out some bottles and cans made of iron from the Qiankun bag, in fact, he preferred the glass test tubes used in the laboratory when he was studying in the past, which were transparent and lightweight, and he could also observe the chemical reactions inside, but unfortunately others could only use this kind of iron pot instead in ancient times.

Zhang Lifeng grabbed twenty Qi Nourishing Waste Pills, threw them into the iron pot, and then poured the mountain spring that had been prepared a long time ago into it.

After a while, these twenty Qi Nourishing Waste Pills slowly dissolved in the iron pot, Zhang Lifeng poured in another twenty Qi Nourishing Waste Pills, this time the twenty Qi Nourishing Waste Pills were not all dissolved, it seemed that the liquid in the iron pot was saturated.

Next, Zhang Lifeng put his right hand on the iron pot, and the palm of his hand began to call the yang fire, and the heat was transferred to the solution in the iron pot, and the solution began to boil.

In the chemistry class of junior high school, Zhang Lifeng had learned most of the compounds in the world, and their solubility increased with the increase of temperature, and I hope that the compounds in this Qi Waste Pill are also the same.

Zhang Lifeng stared at the iron pot tightly, and sure enough, the undissolved Qi Nourishing Waste Pill in it also dissolved with the increase in the temperature of the solution, Zhang Lifeng hurriedly put another twenty into it, and the solution reached a saturated state after dissolving ten more.

Seeing this, Zhang Lifeng filtered out the remaining waste pill that could no longer be dissolved with a homemade strainer and put it in a clean place next to it.

Next, Zhang Lifeng began to put his left hand on the side of the iron pot, and the palm of his hand was running "Ice and Water Mixed Yuan Gang", and the cold energy slowly spread from his left hand to the side of the iron pot, and the inside of the iron pot began to cool down slowly.

When the temperature cooled to a certain extent, small particles began to appear under the iron pot, and Zhang Lifeng hurriedly used a strainer to put these particles in the iron basin numbered A.

The temperature dropped again, and small particles began to appear under the iron pot, and Zhang Lifeng hurriedly used a strainer to put these particles in the iron basin numbered B.

In this way, it cooled down to room temperature little by little, and Zhang Lifeng collected particles from four iron basins A, B, C, and D.

Immediately afterwards, Zhang Lifeng put the particles in the nail basin under his nose and smelled the smell, fishy, put it in his mouth and tasted it, it was spicy, this should be fish scale grass. Immediately afterwards, Zhang Lifeng used this soil method to identify B as a five-flower root, C as a jade stem, and D as a rhubarb grass.

The fish scale grass, five-flower root, jade stem, and rhubarb grass are the four herbs for refining the Qi Nourishing Pill.

That is to say, Zhang Lifeng finally got the method of being able to extract the raw materials of the waste pill, as soon as he thought of this, Zhang Lifeng couldn't hide his excitement, slapped his thigh, just wanted to scream excitedly, and thought of something, gritted his teeth and endured it stiffly.

Now Zhang Lifeng lives in the gathering place of the outer disciples, this voice is called out, for fear that there will be curious people to come to peep, if he discovers this secret, I am afraid that Zhang Lifeng, who is extremely weak now, will become a fish on the chopping board, and let others slaughter and squeeze it.

In fact, this method is only the simplest purification method in Zhang Lifeng's life, using the method of different solubility of substances at different temperatures, and more talented scientists have invented more efficient extraction methods, which can extract purer compounds.

That's because Zhang Lifeng's world has no immortal cultivation, and in order to fight against nature, human beings can only focus all their skill points on science, discover a series of natural laws, and create a great civilization.

But in this world, because of the existence of cultivating immortals, human beings can fight against nature through cultivation, and even break new ground and get more of what they want, so they focus all their skill points on cultivating immortals, and they don't care about the laws of nature and science.

Now Zhang Lifeng has crossed into this world, he is a natural person with scientific education, in the process of trying to climb up in a world of cultivating immortals, the scientific method, management knowledge, various values and historical views he has received will have an impact on his behavior, thus changing his fate.

It's just that Zhang Lifeng doesn't know it now, he is busy, taking out more Qi Nourishing Waste Pills from the Qiankun bag, throwing them into the iron pot, and constantly extracting more herbs.

It wasn't until the rooster's crowing sounded that Zhang Lifeng stopped his slightly trembling hands, and he sat down on the bed, looking at the results of his busy night.

A total of 140 Qi Nourishing Waste Pills were extracted, and the particles of the four herbs of fish scale grass, five-flower root, jade stem, and rhubarb grass were piled up in the four iron basins of A, B, C, and D.

Zhang Lifeng breathed a sigh of relief, even if he couldn't reach the terrifying sixty percent alchemy success rate of Lu Daoren, and only had a success rate of less than four layers of alchemy, then these one hundred and forty Qi Nourishing Pill raw materials could also refine fifty-six Qi Nourishing Pills.

If you only receive Danfeng's meager moon sound, this is the total number of Qi Nourishing Pills that Zhang Lifeng can only receive after a year of hard work!

Thinking of this, Zhang Lifeng couldn't help but feel refreshed, but then he thought about it, and it would take the last refining process to refine these raw materials into Qi Nourishing Pills again.

The origin of these raw materials is unknown, and they can't be rashly taken to the Danfeng Public Dan Room to refine, otherwise there are many people there, and once the news leaks, I don't know how this little minion who refines the first layer of qi will die.

Anyway, it's going to be work time again, so it's better to find an opportunity to ask Lu Daoren. After making up his mind, Zhang Lifeng got up and put away all these materials, rushed to take a large feather fan, and went to the peak of Lu Daoren to start a day's alchemy work.

Time flies quickly, in the evening, Lu Daoren pointed with his right hand, a spiritual energy shot out, the lid of the Dan furnace opened, the aura inside flashed, Zhang Lifeng saw that the success rate of this furnace Qi Dan was more than sixty percent, and it could be seen that Lu Daoren was also very happy.

Many brothers and sisters surrounded one after another, put away the pills inside, and began to clean the Dan furnace and do the finishing work.

While cleaning the furnace wall, Zhang Lifeng took the opportunity to ask Lu Daoren, who was in a good mood, "Lu Daoren is really powerful, the timing of opening the furnace is just right, this is already the fifth Dan furnace I have seen with a Dan rate of more than sixty percent, when can I be as powerful as a Daoist?"

When Lu Daoren was happy, he was very useful to Zhang Lifeng's obedient words, and said, "There is no trick to alchemy, as long as you learn more, watch and practice more, one day, you will be as powerful as me!"

When Zhang Lifeng heard this, the topic came to his own problem, and he hurriedly asked, "Lu Daoren, I want to practice alchemy after I go back, I don't know if there is a Dan furnace that can be borrowed." ”

A Dan furnace requires thousands of spirit stones, and Zhang Lifeng knows that he can't afford it, but he doesn't know where to rent it, so he asks.

Lu Daoren said casually, "This is simple, we in Danfeng have a special Dan furnace for renting for people to refine Dan by themselves, you only need to go to the Danhuo Workshop and bet on a hundred low-level spirit stones, you can get a small Dan furnace, although it is not as fine as the peak Dan furnace, it is more than enough for you to practice your hands!"

"Oh," Zhang Lifeng thought in his heart, if he saved this hundred low-level spirit stones by himself, he would have to save for seven years, and couldn't help but smile bitterly, "Don't hide it from Lu Daoren, this hundred low-level spirit stones is a huge amount of money for me, and the disciple is powerless!"

"Oh?" Lu Daoren's eyes rolled around when he heard this, and he said casually, "This hundred low-level spirit stones are only used for deposits, if you really need ......"

He didn't say the latter words, but Zhang Lifeng knew in his heart that he could borrow this hundred low-level spirit stones or not, but this Lu Dao person would not borrow useless people. Just like in the old workplace, favors are only sold to useful people.

And he Zhang Lifeng wants to express his stance as a useful person.
