Of course, this departure refers to the departure from Wuguan City, which does not mean that during the period of refining the elixir, Cao Jing will not get out of this cave, but will not take going to Wuguan City as his goal.

In the past, Cao Jing had already cultivated the Licang Fire Control Technique and the Liyu Yun Medicine Technique, but because he had never found the Dan Furnace and had never operated it, now Lu Qianchao had sent the Dan Fang, the Dan Furnace and the elixir together, so of course Cao Jing would not miss such an opportunity.

In these three days, Cao Jing first refined the Dan furnace, although it is not a haode Dan furnace, but it is also considered to be the top grade in the Dan furnace, Cao Jing is easy to refine, three days Cao Jing is okay when he sacrifices the Dan furnace to practice, and at the same time, he will also sacrifice the fire to perform, zuihou is to use the seven-needle Xuanshui live medicine technique to refine some elixir, in order to prepare for the use of alchemy pills.

Three days is enough time for Cao Jing to refine enough elixir, as well as to be familiar with the Dan furnace, and with the combination of Canghuo and Dan furnace, Cao Jing also has a comprehensive understanding of fire control techniques, and can skillfully play fire control techniques on the Dan furnace.

Now, Cao Jingpan is sitting in the cave, with the Dan furnace in front of him, the Dan furnace at this time is not the size of the fist at the beginning, after refining, the Dan furnace can change the size at will, in all the aura, there are very few that can change the size, basically some aura with special functions will have this characteristic, the most common is the flying sword and the Dan furnace, most of the even more than ninety out of five spiritual weapons can not change the size, and they can not be included in the body for warmth, can only be held at hand or placed in the storage space.

The Dan furnace in Cao Jing's hand can change in size, but it can't be included in the body, after all, the quality of the Dan furnace is too poor, there is no room for improvement, and it can only be used early, but it is enough for the current Cao Jing.

For the first time refining elixir, Cao Jing chose the detoxification pill with the least number of elixirs, only eight kinds of elixirs are needed, and the grade of the elixir is not very high, the highest is two kinds of first-grade intermediate level, and the others are all first-grade beginners, and there is even an elixir that has just reached the threshold of the elixir, which can almost be regarded as a top-level herb, and when the detoxification pill is refined, the eight elixirs do not need special treatment, only one by one can be put into the refinement.

The two kinds of mid-level elixirs in the detoxification pill are Yuanzhi root, kudzu vine, and the other six are common elixirs with different detoxification functions.

Cao Jing sacrificed the Dan furnace and the Canghuo Water Lotus, after playing a few fire control techniques, I saw the Canghuo Flame in the Canghuo Water Lotus, a moment later, Cao Jing put into the Yuanzhi root that had been purified with the living medicine technique into the Dan furnace, and after playing a few tricks again, he used his divine sense to detect and pay attention to the situation of the Yuanzhi root in the Dan furnace, and separated the divine consciousness to control the size of the flame of the Canghuo, and the alchemy of the pill is a tiring job, not only consuming spiritual power to support the continuation of the spiritual fire, this is still small, the most important thing is to pay attention to the changes in the Dan furnace with divine consciousness at all times, and at the same time control the flame。

And the continuous use of divine consciousness is the most tiring thing, and now it is only the first elixir, Cao Jing already feels as tired as if he has fought a big battle with the Wind Demon Leopard.

A quarter of an hour later, Yuanzhigen has been thoroughly refined, Cao Jing gently wrapped Yuanzhigen spiritual liquid with divine sense, and then put in the second elixir kudzu vine, once again controlling the canghuo refining kudzu vine, this time it only took two-thirds of the time to refine Yuanzhigen to completely refine kudzu vine, Cao Jing once again separated his divine sense to wrap kudzu vine spiritual liquid, and once again put in an elixir...

Half an hour later, Cao Jing has completely refined eight kinds of elixirs, at this time there are eight groups of spiritual liquid in the Dan furnace, not next to each other, one group of one position, at this time has reached the second important part of the alchemy elixir, that is, the fusion of various elixirs to refine the spiritual liquid, and this step is the basis of Cheng Dan, if the fusion is not haode, then it will be directly scrapped into a waste pill or directly into ashes.

Cao Jing controlled the eight groups of spiritual fluid to slowly lean together, cautiously, not daring to touch it easily, zuihou When the eight groups of spiritual fluid were surrounded in the middle, Cao Jing gently let go of his divine sense, and the eight groups of spiritual liquid cracked a gap, slowly gathering in the middle, just when all kinds of spiritual liquid touched, Cao Jing trembled lightly with excitement, and the result can be imagined, eight groups of spiritual liquid' Poof' sound directly into ashes, Cao Jing sighed unlucky, after cleaning up the Dan furnace, Cao Jing took the Canghuo Water Lotus back to the dantian to warm up, and then crossed his knees to restore the consumed divine consciousness, although only one step was completed, but Cao Jing's divine consciousness consumed greatly, after all, it was the first time to refine the elixir, when the divine consciousness was withdrawn, the moment the Dan furnace was put down, Cao Jing only felt that his brain was heavy, and he wanted to sleep hard!

An hour later, Cao Jing slowly opened his eyes, feeling refreshed, and couldn't help muttering: It seems that the alchemy pill is very helpful for the growth of divine consciousness, no wonder the elixir said in his jade slip that the divine consciousness of the medicine master is much stronger than that of the same price, and the divine sense attack of the high-level medicine master is invincible! Now Cao Jing can clearly feel that his divine sense has increased, and since he has recovered, then Cao Jing will no longer hesitate and continue to refine the elixir!

The second time, Cao Jing tried his best to stabilize his mind, but the result was that he did not tremble, but at the moment when the eight balls of spiritual liquid touched, the furnace exploded again, and the spiritual liquid inside turned into ashes.

The third time, after summarizing the previous two times, Cao Jing decided to fuse between each of the two regiments, and then fuse again. As a result, when the second fusion came to fruit, it was ashes again.

......

Two days later, Cao Jing has changed a lot, his body is in a mess, his clothes are noisy and tattered, and there are even pieces of ashes on his face, but his spirit is very good, although his eyes are red, but he is full of energy, look at his cracked mouth, you can know that Cao Jing has gained a lot.

In the past two days, Cao Jing has continued to try, constantly summarized, and finally succeeded in fusing all the spiritual liquid into a ball without blowing up the furnace into ashes, and in one attempt at a time, Cao Jing has also gained a lot of experience, it is better that Cao Jing now needs less than one-third of the original time to refine the Yuanzhi root, and the last six elixirs can refine three elixirs at the same time, and it only takes about a quarter of an hour to complete all the refinement, and Cao Jing's divine consciousness has also increased a circle, extending at least one foot.

Cao Jing decided to take a break, eat a good meal, and then refine the detoxification pill in one go! Su Xue and Cang Yan have been very well-behaved for the past two days, eating the demon pill and sleeping and cultivating, and the breath they emitted made the surrounding demon beasts stay away, not daring to approach, seeing Cao Jing coming out, saying that they wanted to eat, Su Xue and Cang Yan were going to hunt, Zuihou or Cao Jing said that Su Xue went hunting, and Cang Yan went to find firewood to end the quarrel between the two little guys.

As a result, Su Xue brought back five gray pheasant demon beasts, a reindeer demon beast, and the gray pheasant needless to say, it is the descendant of the colorful golden pheasant, and the reindeer is actually a very docile animal, almost no aggression, but the speed of the reindeer demon beast is definitely the fastest, although the meat of the reindeer demon beast is one of the best demon beast meat, but there are very few that can be eaten, and now Cao Jing because Su Xue has eaten it, looking at the body of the reindeer demon beast that was caught, he knows that Su Xue used the cold ice qi to catch it.

An hour later, all the gray pheasants and reindeer were roasted, Cao Jing ate a gray pheasant, and then feasted on three catties of reindeer meat, after eating, Cao Jing was very satisfied, praised the reindeer meat delicious, it is a delicacy in the world! Before entering the alchemy pill, Cao Jing put two gray pheasants and ten catties of reindeer meat into the storage bag on his waist as a decoration, and prepared to use it during the alchemy of the elixir. When he was in the reindeer meat, it also aroused the strong dissatisfaction of Su Xue and Cang Yan, knowing that Cao Jing could only pass the test by threatening with pills!

Entering the cave again, Cao Jing breathed for half an hour, and then began to refine the elixir again, this time it was very smooth, and after a quarter of an hour, the spiritual liquid of the eight elixirs was perfectly fused together, and then Cao Jing looked solemn, and now it is the third step, that is, Cheng Dan, this step determines the rate and color of the pill.

After the spiritual liquid melted into a ball, Cao Jing's gesture suddenly became faster, and various tricks hit the Dan furnace one after another, and the spiritual liquid in the Dan furnace was also constantly changing, and there were impurities volatilizing from it, the spiritual liquid continued to shrink, constantly rolling, and all kinds of elixir and spiritual liquid were completely fused together, and after waiting for the tea kung fu again, the magic formula in Cao Jing's hand changed again, this is the magic of Cheng Dan, the number of Cheng Dan, the color of the pill is uncontrollable, and it is only known after the Dan, but the experienced medicine master can roughly judge the color according to the medicinal fragrance of Cheng Dan and the situation in the refining process, but the number of pills is difficult to judge.

After playing the trick, Cao Jing stopped his hands, and at this time, the Dan furnace spontaneously continued to rotate, and the Canghuo Water Lotus was also under the control of the divine sense, constantly changing, cooperating with the Dan furnace to give the most suitable temperature.

Time passed minute by minute, the Dan furnace rotated faster and faster, and the medicinal fragrance became stronger and stronger, although he was also very happy in his heart, but Cao Jing did not dare to relax, for fear that he would blow up the furnace after shaking again, and now it was about to succeed, Cao Jing became more and more careful, waited calmly, and carefully controlled.
