In the chat, Li Fei learned that one of the hard criteria for an advanced advanced alchemist, that is, a "master", was to use the only pseudo-"heaven" level tripod in the Danji Sect to successfully refine a furnace of pills. ○

The reason why a "pseudo" word is added is because the function of this tripod is far beyond the ordinary "earth" level tripod, but it is obviously different from the real heaven-level tripod. The biggest difference is that this pseudo-emperor tripod is very large in size and cannot be refined, so it can only be fixed in one place. Another headache is that a large amount of elixir must be put in at one time, and if there is too little, it will not be successfully refined, which seriously limits the conditions for use. Under normal circumstances, no one is willing to take such a big risk, using a lot of elixir to gamble to save that little bit of time, and refining it many times with ordinary prefecture-level dings, the risk is much smaller.

It is said that even the monks of the advanced "master" are also forced to use some lowest-level elixir to break through this level, and they will not lose much if they fail. This also led to the puppet emperor tripod being idle for a long time, and no one used it for many years.

When Li Fei heard the news, he was attracted by its positive effects. Although the Pseudo-Emperor Ding has obvious disadvantages, it also has obvious benefits. First of all, you can refine a large number of pills at once, saving a lot of time.

Li Fei was already a little impatient with the fact that he was spending a lot of time refining the spirit pill frequently, and at the current rate, the remaining spirit pill materials were still enough to refine for eight * nine years, if he could use the Pseudo-Emperor Ding to get it all at once, most of the time in the ten years would be saved, whether it was used for cultivation or refining other pills, it would be greatly beneficial.

Secondly, due to the higher level of the Pseudo-Emperor Ding, compared with the prefecture-level Ding, the success rate can be improved to a certain extent, and in terms of the quality of the pill, there is also a higher probability of high-quality pills, and there are lower possible top-grade pills.

In general, if you have a relatively large grasp of refining a certain elixir and can withstand the loss of failure, it is still a good choice. After comprehensive consideration, Li Fei decided to challenge on the basis of full preparation.

In the next three months, Li Fei just refined all the elixirs of the elixir, and no longer refined the elixir, and after all the refining was completed, he asked Mentor Wujing for two months to officially challenge the pseudo-emperor Ding.

Li Fei applied for a two-month deadline from the Danshi who managed the Pseudo-Emperor Ding for the reason of observation, but he didn't expect it to be approved very smoothly. This is because although there are very few people who use the pseudo-emperor ding, there are not many disciples who want to visit, and they generally go to see it to increase their knowledge.

Half an hour later, Li Fei came to a medium-sized extinct volcano in the central area of Yellowstone Academy. Due to the unique status of the Pseudo-Emperor Ding, there are no other Dan Rooms in this medium-sized extinct volcano, only a Super Great Dan Room where the Pseudo-Emperor Ding is placed. For the safety of Ding, all kinds of reinforcements and defensive prohibitions are extremely powerful, even if this extinct volcano has a large eruption, it will not cause the slightest damage to the Danfang.

Due to the countless powerful prohibitions, this Dan room was not guarded by personnel, but was only regularly inspected by the management department, so after Li Fei opened dozens of prohibitions with a special spirit card, he successfully entered this super Dan room.

As soon as he entered, Li Fei was strongly shocked by the huge puppet emperor tripod in front of him! The puppet emperor tripod, which was more than five zhang high and more than three zhang in diameter, was placed in the center of the hall! Below the puppet emperor tripod, there were nine Dan furnaces alone, arranged according to certain rules. Near the Puppet Emperor Ding are two large movable multi-functional elixir inspection cabinets, and ten zhang away from the Puppet Emperor Ding, surrounded by a circle of stone doors, it is estimated that there are dozens of rooms.

For the sake of prudence, Li Fei first carefully inspected the hall and every room, and found no abnormalities, but found that three of the rooms were small Dan rooms, which were probably used for some preliminary work, and finally began to check the pseudo-Emperor Ding.

Li Fei played five tricks in a row, and after a soft "buzz" sound, the lid of the tripod slowly opened, and finally hovered a few feet above the mouth of the tripod. Li Fei jumped lightly, jumped up, stood at the mouth of the dingkou and observed, and found that in addition to the dozens of big buckets where the elixir was placed, the trough where the final collection of Cheng Dan was densely packed, there were dozens of layers, and the formations of various sizes were countless.

Although the interior of the Pseudo-Emperor Ding was well maintained, it took Li Fei three full days to clean it up according to his own requirements, and finally carried out three automatic cleaning according to the method recorded on the Pseudo-Emperor Ding before the lid was restored. After Li Fei cleaned up the puppet emperor ding, he carefully inspected and cleaned up the elixir cabinet, and then opened the Dan furnace one by one to check the operation of the Dan furnace.

After completing all the inspection work, Li Fei took a high-grade elixir and began to cultivate. Three days later, Li Fei finished his cultivation, bathed and changed his clothes, adjusted his state to the best, and officially opened the furnace for alchemy.

The basic process of alchemy is not much different from Li Fei's previous use of earth-level tripods, mainly because the preheating time in the early stage is longer, and the most important step is the second important step of alchemy, because there are too many elixirs loaded at one time, the alchemy process needs to continue to quickly change the recipe is extremely frequent, and it requires extremely skillful techniques and adaptability, and a little carelessness may lead to failure. Of course, upfront preparation is still a basic prerequisite for success.

After Li Fei rehearsed all the steps and every detail in his heart, he played a trick, opened the first Dan furnace, preheated the Danding, and then opened all the Dan furnaces one by one according to the corresponding timing.

An hour later, Li Fei played the last trick on the Dan Furnace, adjusting the flames of the nine Dan Furnaces to just right, and evenly preheating the Pseudo-Emperor Ding. As the preheating of the Pseudo-Emperor Ding was almost completed, there was a faint sound of wind and thunder in the Pseudo-Emperor Ding.

Three hours later, Li Fei had already turned the flame of the Dan furnace into a light purple, and after two hours of warm-up, the pseudo-emperor Dingzhong had regained his calm, and quickly played a string of magic tricks, and with a muffled sound, the Ding Gai flew up, hovering in the air about a zhang away from the mouth of the Dingkou to remain still.

Li Feiyue went up the steel ladder prepared in advance and checked the situation inside the Puppet Emperor Ding. At this time, the dense earthy yellow fog inside the Pseudo-Emperor Ding kept rolling, and small electric sparks appeared and disappeared from time to time. After Li Fei tried with his divine thoughts to no avail, he had no choice but to continue to observe the changes with his naked eyes.

When the Pseudo-Emperor Ding was relatively calm and the yellow mist showed a faint red color, Li Fei began to get busy in a nervous and orderly manner, quickly putting a large amount of refined elixir into the big bucket in the Danding, and at the same time strictly controlling the stability of the flow rate of the elixir in the big bucket, and fine-tuning the firepower of different furnaces in a timely manner......

The process of alchemy lasted for nine days, and after the lid was closed, it finally entered the relatively easy stage of Yundan. Although Li Fei felt very tired, the accumulation of alchemy experience over the years, coupled with the progress of his cultivation, finally did not exceed his previous expectations and successfully completed this crucial step.

Taking advantage of the relatively stable gap that had just entered the Yun Dan stage, Li Fei relaxed a little, and then continued to cheer up and watch the progress of Yun Dan. After all these years of continuous alchemy, Li Fei summed up his own set of methods for the Yundan stage, no longer maintaining a high degree of tension all the time, but relaxing to a certain extent, relaxing as much as possible in a relatively safe time period, recovering physical strength and energy, so as to better adapt to the high-intensity alchemy process, reduce human errors, and improve the success rate of alchemy.

This time, the Yundan phase lasted eighteen days. During this period, there was an accident, in the final stage of Yun Dan, the pseudo-emperor Ding suddenly had a small vibration, as if a beast was locked inside, shaking endlessly. Fortunately, it didn't last too long, and after Li Fei blessed more than ten stable prohibitions, he slowly regained his calm.

Li Fei didn't know why this happened, he could only hope that there was no big adverse effect on the pill, otherwise he would really want to cry without tears. Although Li Fei was mentally prepared in case of failure when he decided to use the Pseudo-Emperor Ding Alchemy, he still felt a great loss when he really had the possibility of failure, and felt that this kind of price was too great for ordinary monks to bear.

After a long ordeal in the last few days, Li Fei finally survived. When he smelled the faint fragrance of medicine, Li Fei was so excited that he danced, and he really hoped that someone could share the happiness at this time! The suppressed nerves were instantly liberated, and the joy similar to the rest of his life after the catastrophe is difficult to describe in words......

As the entire hall was overflowing with medicinal incense, a muffled sound came from the puppet emperor's ding, and the lid of the ding opened automatically. Li Fei laughed and jumped onto the steel ladder, looking at the dense and uncountable spirit pills, he felt too happy...... After all the furnaces have been completely turned off, prepare for harvest.

In order to prolong this rare joy, Li Fei did not use the built-in function of the Pseudo-Emperor Ding, and collected all the pills in a super-large container at a time. However, for a while, Li Fei really didn't have a suitable container to collect so many pills, and he would never use plastic buckets to pack them, which would not be conducive to the preservation of pills.

Since Li Fei had harvested a large number of various jade stones in previous battles, he decided to temporarily make dozens of large jade bottles that could hold thousand-grain elixirs.

After more than an hour, Li Fei made forty or fifty super-large jade bottles in one go, and almost used up all the large pieces of jade that could be used.

In order to facilitate the screening of different qualities of the elixir, Li Fei decided to only take a hundred pills at a time, and then put them into three different large jade bottles. In the process of collecting, Li Fei was pleasantly surprised to find that the number of high-grade and medium-grade elixirs was much more than he imagined. It didn't take long for a bottle of thousand-grain jade to be filled with ordinary elixirs, and Li Fei had obtained twenty-six pills of high-grade elixirs alone! More than 300 medium-grade elixirs.

When Li Fei collected ten bottles of the elixir, he found the most special "guy", the whole body was blood-red, and the volume was slightly larger than the high-grade elixir, almost catching up with the size of the newborn egg. Li Fei sniffed it and found that in addition to the aroma of the normalized elixir, there was also a faint smell of blood!
