Although there are quite a few people in this "big family", it can still be easily accomplished for a True Yuan Realm monk. The rest of the time, Tong Lao carefully taught Luo Tian alchemy, and occasionally pointed out Qingzhu.

As early as a month ago, Yunye Zhenren came to Luo Tian. At that time, Luo Tian and the third uncle explained the situation. It was difficult to repay the teacher's kindness, and Yun Ye, who learned of the situation, also agreed with Luo Tian to stay.

Yun Ye Zhenren gave Luo Tian a piece of the family token, telling him that if he arrived at the family, he could use this token to find himself. Before leaving, he also gave him thousands of instructions to let Luo Tian cultivate well, and also gave him a lot of pills and cultivation resources, and then left the Dust Cloud Country with confidence!

After Yun Ye Zhenren left, Luo Tian no longer thought about other things, but wholeheartedly followed Tong Lao to learn the way of alchemy!

Time passed day by day, and Tong Lao and Luo Tian seemed to live in a paradise. In addition to going hunting every day to help everyone get food, Luo Tian concentrates on cultivation the rest of the time, and sometimes studies Danfang!

As the name suggests, Danfang is the ingredients and precautions recorded in refining Danyao. To put it simply, every pill will have a pill, and without a pill, the alchemist will not know how to refine the pill. Of course, if the pill has been refined many times, then the pill is in the heart.

Most of the pills indicate the efficacy, effect, refining details and so on. Of course, this is only an empirical theory. How to successfully refine a pill still depends on whether the alchemist will learn and use it. In addition to Danfang's explanation, Master's personal guidance is also very important.

Now Luo Tian can control the three flying needles to fly freely. It's only been a month since Yun Ye left. Since he knew that his old age was short, Luo Tian practiced harder.

Luo Tian is a monk of the True Yuan Realm, and he can basically keep it for two days and two nights without rest. But if this is the case, then on the third day you need to have a complete rest to recover. So it's better to take a short break every day, so it will be more efficient!

The first flying needle, Luo Tian spent a month. Today's three flying needles have been done in just one month. In other words, as long as the first flying needle can be successful, it will be mastered faster and faster, because the first one is a foundation!

At this rate, Luo Tian still needed three months to complete the cultivation of the ten flying needles. But he didn't want to waste his time on that. So just a month later, after unremitting efforts, Luo Tian finally controlled the seven flying needles! His speed doubled again. In a month, he mastered four more flying needles.

Luo Tian happily told Tong Lao the news. At this rate, Luo Tian would be able to complete all his cultivation in just four months. This shocked Tong Lao, it took him three months to master the control method of one flying needle, and his own apprentice actually took four months to master the most basic control method of ten flying needles. It's really better to be blue than blue!

Generally speaking, in addition to the basic control techniques, he also needs to read many pills to increase his experience. However, Luo Tian's homework has already been completed. Now Tong Lao has learned all the Dan prescriptions below the third grade. It can be said that as long as Tong Lao says the name of the elixir, Luo Tian can recite it all!

"Master, which Dan recipe should I start refining and learning first?" Today, Elder Tong called Luo Tian and said that he would teach him how to refine the pill. So Luo Tian was very excited, and he was finally able to officially alchemy.

"The next thing is to learn how to extract spirit herbs, of course, the failure rate will be high at first, so learn to extract from ordinary herbs first. Next, when you hunt, you have to pick more herbs and come back!" said Tong Lao slowly.

"Ah, Master, isn't it alchemy?Why do you still want to extract it?" Luo Tian was a little helpless, he wanted to show his skills, but he didn't expect that Master taught himself alchemy, and he actually had to start with ordinary herbs, and most importantly, he had to return to his old profession of collecting medicines.

"Well, don't you want to learn? Okay, don't come to Master to learn in the future, you can study how to make alchemy yourself!" Tong Lao said with his eyes closed. It seems that he is a little dissatisfied with the apprentices.

"Eh, don't, Master, can't I collect medicine? By the way, do you need to collect some elixir and come back? Today, the apprentice's sensing ability is about a thousand square feet. Therefore, it is more convenient to find spirit grass. Luo Tian could only promise Master.

"Yes, yes, but don't go too deep into the jungle. When encountering a demon beast above the third order, you can't fight with it. Every time I go out, I bring Yu'er and Bo Zai, so that I can take care of it" Tong Lao is still very concerned about Luo Tian's safety. However, with Yu'er, a guy who escapes at high speed, he can easily avoid any demon beast when he encounters it.

Bo Zai's current realm has also reached the state of the peak of the second order. I believe that it will not be long before we can break through. Of course, this still needs chance, if the demon beast doesn't have any chance, it is very difficult to break through the realm!

Extraction is to extract useful ingredients from medicinal materials and separate them with true qi control, which is why I used to practice control control zhì flying needles. In order to be able to better control the herbs with true qi.

However, the control strength of each herb and flying needle is also different. So these still need a long time of experience. There is a good saying that alchemists are fed with countless cultivation resources. It can be seen how much this alchemist consumes heavenly and earthly treasures. This is not something that Tong Lao can afford alone.

Therefore, Tong Lao also said that Luo Tian could leave when he reached the first grade alchemist. This is also to let Luo Tian go out and exercise. Only in this way can we improve our strength faster. Whether it is the cultivation realm or the level of alchemy, there will be a process of rapid growth!

For the next month, Luo Tian not only hunted every day, but also took care of collecting herbs for himself to learn to extract. Therefore, he usually hunts more prey, which is enough for them to use for a few days. Then he picked up the basket and took Bo Tsai to the mountains to collect medicine. Generally, it takes up to three to five days to return to the village. He would not go deeper than five hundred miles into the Demon Beast Mountain Range. Because further inward, it is the territory of the third-order demon beast.

The periphery of the Demon Beast Mountain Range is relatively clearly divided. Within two hundred miles is the infested range of first-order demon beasts. Five hundred miles is the survival range of second-order demon beasts. When it reaches more than five hundred miles, it is the range of third-order demon beasts. More than 1,000 miles is the staggered survival range of third-order demon beasts and fourth-order demon beasts. Demon cultivators live in the depths of tens of thousands of miles. Of course, this is only the situation of the Demon Beast Mountain Range bordering the White Eyebrows in the Dust Cloud Country. As for the delineation of other regional scopes, the situation may be different.

Luo Tian didn't enter the third-order demon beast territory because he was afraid of trouble. Although Yu'er was there, not many demon beasts below the fifth order could catch them. However, third-order demon beasts are often encountered in it, so it will affect the speed of collecting medicine. Besides, Luo Tian didn't need such a good spirit grass now. I just need some common herbs.

In this way, after a month, Luo Tian basically mastered the technique of extraction. I saw that he was sitting next to an alchemy furnace at the moment, holding an ordinary medicinal herb with his true qi in both hands.

The herb was wrapped in true qi, and then slowly flipped in the burning Dan furnace. The first thing is to let the fire dry it out and evaporate some of the useless liquid inside. Then Luo Tian controlled his true qi and squeezed the herb vigorously.

After a while, the ordinary herb was squeezed out a little sap. Of course, the juice is still attached to the herb residue. What Luo Tian has to do is to separate it! Now is the time to test the true qi control power!

Luo Tian slowly separated a small stream of true qi, and then slowly separated the drops of medicinal ingredients from the branches and leaves. Then he took control of the remnants of the herbs and moved outside the Dan furnace!

"Well, yes, you are seventy percent sure that the extraction will be successful in one month, which shows that you are making rapid progress. If you want to improve the chance of successful extraction, you need more time to practice, which is not something that can be done in a short time!" Tong Lao was very satisfied with Luo Tian's watch.

Luo Tian was also very happy to hear Tong Lao's praise, because the next step was purification. The separated useful parts must be purified before they can be further refined. In this way, Luo Tian entered the next stage of cultivation.

Tong Lao prepared a lot of ordinary medicinal liquids for Luo Tian. Luo Tian first started refining from a fist-sized volume. Then gradually reduce the amount until finally a drop of liquid medicine is purified, so that it can be regarded as meeting the requirements of the elderly. The less liquid the medicine, the more difficult it is to control. And it must be the true qi of wood or the true qi of fire to proceed better.

At first, it was very smooth, and Luo Tian only improved when he practiced to a volume the size of a thumb. The size of a thumb is about a dozen drops. At this time, Luo Tian seemed to feel that he couldn't make any further progress!

If it is calculated according to the purity of purification. Luo Tiancai can reach a purity of fifty percent, which is far from enough. According to the meaning of Tong Lao, at least more than seventy percent of the purity can be achieved!

Luo Tian was very helpless, Tong Lao was really strict in terms of alchemy. It's no wonder that Tong Lao, the so-called strict teacher produces a high apprentice. Setting the bar higher will have a big impact on future progress.

Generally speaking, for others, whether it is the success rate of extraction or the purity of purification, it is already very good to reach 50%. And Tong Lao all demanded that Luo Tian reach at least seventy percent! It can be seen how strict it is.

Only when a drop of liquid medicine is successfully purified can it be regarded as reaching the standard of 70% purity. So Luo Tian still needs to work hard. He didn't complain about anything, Luo Tian knew it was for his own good. Therefore, he began to immerse himself in the study of purification methods.

Purification, to put it bluntly, means that the separated liquid contains impurities, so it is necessary to further remove impurities. Therefore, Luo Tian felt that this seemed to be similar to the principle of extraction. That is to find out which are impurities and which are useful parts first. This is where inward vision comes in.

He felt that self-introspection could not only observe the situation inside himself, but also be used for alchemy. Luo Tian had a whim and felt that it could be used in this stage of purification. Most of the impurities in the liquid medicine are relatively small. Sometimes it's not always visible to the naked eye. It is also possible that the impurities are liquids like the liquid medicine, so it is more difficult to purify.

What Luo Tian has to do now is to control the liquid medicine while controlling it, and then he must also relax himself. Let yourself reach a state of self-inward view, so that you can observe the existence of impurities. This is more difficult than simply looking inward, after all, you have to separate your mind to control the liquid medicine. If you are not careful, the liquid will fall into the fire and be incinerated against.

But he is not afraid of failure, and if he doesn't work once, he will come again. After cultivating for a long time, Luo Tian was finally able to control the medicinal liquid while entering a state of self-inward-looking. However, at this moment, his "inner vision" is the inside of the liquid medicine. This ability can be called outward vision.

He saw that the liquid that was originally transparent was actually full of colors inside. As a result, he could not distinguish between useful ingredients and useless impurities. But one thing is certain, and that is to separate the impurities of different colors, and the liquid will be divided into parts, and then you will know which parts are useful.

Just do what he says, and at this moment he must be more careful to separate. After the separation was completed, Luo Tian found that in each color, there would be more or less substances of other colors. It doesn't seem to be 100% purified. Luo Tian also knows that it is very difficult to completely separate, so he does not force it.

After the separation was completed, Luo Tian withdrew from the state of external vision. At this time, surrounded by his true qi, a few very small drops of liquid appeared, and they actually took on color. Luo Tian controlled a few drops of liquid one by one and moved them into his mouth, and finally he personally tested the medicine and determined that the red droplets were useful ingredients, and the others were impurities!

Just when Luo Tian was doing this, he was discovered by Tong Lao, who came in to check. Tong Lao couldn't help but be stunned!"More than eighty percent purity!How is this possible!" Tong Lao was deeply shocked.

Oh my God, an apprentice who had just begun to learn alchemy was able to purify the medicinal liquid to more than eighty percent. It's nothing short of a sensational miracle. You must know that some high-level alchemists can only reach this level! Although there is only a 10% difference between 70% and 80%, it is an insurmountable height!

"How did you do that?" Tong Lao stepped forward in surprise and asked, Luo Tian wondered, is it so difficult to purify? Their method of purification is to slowly calcinate it in a Dan furnace with fire. Seeing that Tong Lao was so curious, Luo Tian told Tong Lao his method!

Generally speaking, the useful parts of the herb are not afraid of fire, but impurities can be slowly destroyed by fire. This is the basic theory of the separation of other alchemists. Although there are many alchemists who can achieve inner vision, no one has yet connected inner vision with the purification of alchemy. It can be said that Luotian has created a new way of purification. Even Tong Lao didn't think of it!
