No matter what, Du Fan is a scientist and is a person with perseverance and will not give up easily.

After a little rest, I started to meditate again with my eyes closed.

In this way, Du Fan spent the next three days in meditation and sensing the spiritual energy of heaven and earth.

On this day, Du Fan, who was sitting cross-legged on the wooden bed, opened his eyes again, still full of disappointment, but the next moment, his eyes suddenly lit up, as if he was thinking of something important.

Du Fan touched his robe with one hand, and suddenly a small green bottle appeared in his hand. The items contained in it were the ten Qi Refining Pills I bought at the alchemy office that day.

"I have never heard of it. I started taking pills to improve my cultivation before I became a cultivator. I don't know if there will be any problems when taking it now. I don't care. If this continues, I'm afraid I will never reach the quasi-qi refining stage."

Du Fan felt a sense of decisiveness in his eyes. He opened the green bottle and suddenly a fragrance came out of the bottle and instantly filled the entire room.

After hearing this, Du Fan felt relieved. Even the fatigue caused by meditation had dissipated a lot. When he was excited, he poured out a Qi Refining Pill without hesitation.

This pill is half an inch in size, and is milky white all over. A white halo is emitted on the surface of the pill. When you put it in your hand, a cool feeling penetrates into the flesh along Du Fan's palm, which is very comfortable.

A flash of splendor in his eyes, he raised his palm and instantly sent the pill into his mouth. The pill turned into a cool air when it entered his mouth, which slid into the stomach and hiding along the intestines. Wherever he passed, it was extremely comfortable.

After a moment, the cool air spread instantly, and a huge force exploded from the center of the air mass. The violent turbulence filled Du Fan's internal organs in an instant, causing Du Fan, who was still extremely comfortable just now, to scream in an instant, with blue veins on his face, and cold sweat appeared in an instant.

Du Fan felt that his whole body was about to explode, and a feeling of pain that reached the extreme stimulated every nerve of Du Fan. It was really worse than death. At this moment, he felt that maybe he could feel better if he died.

He just persisted for a few breaths and then fell into a coma with a muffled groan.

When he woke up slowly, he felt weak all over, his clothes were covered with sweat, and his whole body was full of pain. He barely stood up, and this action alone made his eyes dark and he almost fainted again.

He walked out of the hut and found it dark outside. It must have been late at night. After observing a spiritual herb for a while, he was sure that he had just been in a coma for a long time and couldn't help but breathe a sigh of relief.

After walking around the medicine garden for a long time, he felt that his physical condition had improved a little, so he returned to the house again.

After sitting cross-legged, he silently used the Little Five Elements Art in his heart. After a while, a sigh came out of Du Fan's mouth.

"It's still impossible to sense the fluctuations of the spiritual energy of heaven and earth."

Du Fan showed bitterness on his face, and he was helpless about his qualifications. After a moment of confusion, his eyes burst out again, and he poured out a Qi Refining Pill and swallowed it in one mouthful.

After a moment, Du Fan fell into a coma after another shrill scream.

When he woke up again, it was the morning of the next day. In addition to the pain that was full of heart, Du Fan was even more tired. The feeling that his whole body was almost bursting with energy in his body made him feel scared. At this time, a strong sense of hunger came instantly, and he had to eat something first.

When Du Fan climbed onto the wooden bed again, the third Qi Refining Pill suddenly appeared in his hand...

A week later, Du Fan was extremely weak, his eyes were covered with red bloodshots, and his spirit was depressed, but his expression became even more crazy, his head was disheveled, like a demon in hell.

"Haha..." A burst of laughter suddenly came out of Du Fan's mouth, his voice hoarse, like a half-dead old man, and at the same time the tone was extremely sharp, and it was mixed with sounds similar to bone friction, which made people feel scared.

"I finally broke through! After taking the seventh Qi Refining Pill, I finally advanced to the quasi Qi Refining Period. I can finally sense the fluctuations of water spiritual energy between heaven and earth!"

Du Fan's whole body was trembling and twisting. This was a sign that his body was on the verge of collapse after suffering huge pain, but he ignored it and had already numbed the heart-wrenching pain. At this time, he was as crazy as if he was alive in a desperate situation.

There is no such thing as a person who uses this method to break through the quasi-qi refining stage, but there is absolutely no such person who takes Qi Refining Pills like him in a row. Not to mention whether Qi Refining Pills can bear the expenses for mortals who have not yet reached the quasi-qi refining stage. That is, the risks and the great pain they bring, which are not something that ordinary people can bear.

This is not only a huge pain that makes people almost collapse. The most important thing is that the huge impact caused by the explosion of this cultivation pill in the body of a mortal, if you are not careful, the user will explode and die. After taking a mortal, the probability of explode and die is about 50%. However, Du Fan took it seven times, which cannot be said that his luck is not ordinary.

Of course, most other people do not have the opportunity to take Qi Refining Pill seven times as a mortal body. Even if the qualifications are extremely bad, they can take Qi Refining Pill one or two at most. If they do not die, they can break through to the quasi-qi refining stage. It can be seen that Du Fan’s cultivation qualification is not ordinary.

A day later, Du Fan finally regained his peace. He entered a strong pond in the medicine garden and cleaned the sweat stains that had been soaked in his body for the past week. After changing into a clean set of clothes, he continued to sit cross-legged on the bed and began to breathe. At this moment, he could absorb the sensed water spiritual energy into his body, but his absorption was so slow that it made people desperate. The use of spiritual energy to open up the meridians was even more distant for him.

Half a day later, Du Fan opened his eyes and his face turned a little ugly again.

"Why are the meridians in my body so shriveled? It is difficult to open up through the spiritual energy of heaven and earth as mentioned in the martial arts."

He was very helpless about his own situation, and then he thought of Qi Refining Pill again.

"I have now advanced to the qi refining stage. I believe it will be fine if I take the Qi Refining Pill again. However, this Qi Refining Pill is definitely not cheap. With my qualifications, I don't know how many pills I need to take to open up the meridians of the whole body, and then communicate the innate essence in the body and generate magic power."

Du Fan got up and got out of bed. After understanding his own situation, he was not in a hurry to practice.

After walking to the medicine garden for a check-in, he returned to the hut again and began to fiddle with a bunch of miscellaneous items he bought from Sangcheng. He poured the package of miscellaneous items onto the wooden table, and suddenly rolled down many bottles and jars, including bowls and basins, and the materials and shapes were very mixed.

Looking at the pile of items on the wooden table, Du Fan pondered for a while and began to sort them out.

"This thin transistor can replace test tubes. It is easy to say that the container for holding liquids is not a problem with heating instruments. The instruments for filtering and separation are a bit troublesome, but this decoration can be barely replaced." Du Fan murmured to himself, while his hands kept moving, and finally used iron wire objects to fold into a strange-shaped rack. After some fixing, most of the bottles and cans purchased were hung on the wire rack. Most of the bottles and cans were connected to each other.

Du Fan walked out of the house and walked in with an iron pot after a moment. There was water in the iron, and the black Taotie hair was placed on the ground and then went out again. After he came in again, he held a large amount of bricks and stone objects in his hand.

Not long after, Du Fan used bricks and stones to build a simple stove in the house. After a while, he took a lot of firewood and put it into the stove to ignite the fire. He then put the iron pot containing Taotie's hair on the stove.

He turned around and pulled out a thicker leather tube, put one end in the iron pot water, and inserted the other end into a large bottle. The bottle was also fixed by an iron frame, and except for the thick leather tube, the bottle had only another outlet left, and all other places were closed.

Next, Du Fan worked on the iron rack for a while, and lit the oil lamp under a strange vessel to burn it. After a stick of incense, he breathed a sigh of relief.

"I can only do this with my current means, but it should be possible to use it."

If the people on Earth saw this iron rack and what was on it, they would definitely be surprised, because this is a basic set of chemical experimental instruments.

"The boiled Taotie hair water should be injected into the vessel, and then filtered, separated, distilled, crystallized and other processes. In the end, the Taotie water powder should be extracted, and its purity is naturally far above Taotie hair water."
