Bai Ling was ready, and only then did he take out the materials and prepare to start refining the Netherworld Pill. There are really a lot of materials required to refine the Netherworld Pill, it is enough to see that the difficulty of refining the Netherworld Pill is not low, but fortunately, Bai Ling is very confident in his alchemy technique, and he will definitely be able to succeed.

Bai Ling first preheats the Dan furnace with a three-flavor real fire, and then puts in the same materials according to the order. The refining of the Netherworld Pill is very complicated, even if Bai Ling refines it himself, I am afraid it will take a lot of time, after all, the Netherworld Pill is not an ordinary pill.

With the input of medicinal materials, under the action of the three-flavor true fire, the medicinal materials in the Dan furnace are slowly refined into essence, impurities are removed, and the medicinal liquid is at the bottom of the Dan furnace, under the control of Bai Ling, one complex reaction after another occurs, and the medicinal fragrance is slowly passed out.

Fortunately, the undead world is full of undead, not other beings, otherwise, with this medicinal incense, I am afraid that it will attract many other creatures to come, after all, it is also beneficial to absorb the medicinal incense. Thinking about refining the Nether Pill in the Undead Realm, it can not only provide a steady stream of death qi, but also provide a relatively quiet environment.

As time passed, Bai Ling put in more and more medicinal materials, and the refining process was very smooth, and it was time to put in the most important medicinal material, the petals of the Nine Shadows Lotus. The Nine Shadows Lotus is very rare, so there is only this one medicinal material, if the refining fails, it will really fail.

Other medicinal materials can be obtained again, the Nine Shadows Lotus, and Bai Ling can't get them. Therefore, Bai Ling raised his spirit of 120,000 points, and he didn't want to be in such a situation. Falling short.

Fortunately, Bai Ling's alchemy technique did pass, and soon the Nine Shadows Lotus also turned into essence and was mixed with other medicinal materials. With a few more auxiliary medicines, there is no need to add anything now, just wait for the Netherworld Pill to take shape.

At this time, the conditions for refining the elixir in the undead realm were revealed, and the pills that had not yet been formed slowly began to absorb the surrounding death qi, and it was very fast that it was obviously the death qi. It represents death, but the post-death qi absorbed by the elixir formed by the mixing of these medicinal herbs has become full of vitality.

A steady stream of death qi was absorbed by the elixir. Bai Ling knew that the more this elixir absorbed the qi of death, the better the quality, and if the top-quality elixir was refined, then the strength improvement would not be a layer. Raising one level is just an ordinary Nether Pill.

Bai Ling uses his own methods. A formation was arranged to gather the qi of death, and the endless flow of death qi around it immediately surged over, the qi of death around the Dan furnace was much richer, and the Netherworld Pill also increased the speed of absorbing the qi of death, and the pill was formed at a speed visible to the naked eye.

The aura of death was originally gray, but now the entire Netherworld Pill has changed from green to black due to absorbing the Netherworld Qi, and the whole pill looks weird. But that's not the final step. Until the elixir no longer absorbed the qi of death, Bai Ling continued to refine the elixir.

The next refining is the time to truly test the level of an alchemist. Bai Ling slowly refined the Netherworld Pill, and the Netherworld Pill slowly faded from the original black, and in the end, it became a snow-white pill with a whole body, at this time the pill was already restrained, and the original rich medicinal fragrance was gone, but this is a successful pill, and those pills that can exude a medicinal fragrance when they smell it are just low-grade pills.

At this time, the pill has been almost refined, and the last step is about to open the furnace, I don't know how many pills can be harvested this time, Bai Ling is looking forward to it. It took 49 days to refine this furnace of pills, and it was really a painstaking thing to stay in this dark place for 49 days, and to always pay attention to the pills in your hands.

But at this time, it was the time of harvest, everything was worth it, taking out the prepared jade bottle, Bai Ling made a trick, opened the pill furnace, and immediately a few pills flew out, Bai Ling put these pills into the jade bottle, and this time the refining harvested a total of 25 pills, which made Bai Ling overjoyed.

What made Bai Ling even happier was that the quality of the pills refined this time was also very good, and there was no catastrophe when it was baked. It may be that the rules of the world are different, so Bai Ling refined such an anti-heaven elixir, and the Heavenly Dao here did not punish him. This made the pill lose again, and if the 25 pills went through the Heavenly Tribulation, it would be good to have a few left.

But there is no problem in thinking about it, after all, the pill refined by Bai Ling is only to improve the level of cultivation, and the people here are all cultivation magic, which is basically useless, and the Heavenly Dao naturally does not feel any threat, and it is impossible to descend the Thunder Tribulation.

This made Bai Ling very glad that he was refining the elixir in the undead realm, if he chose another world, maybe he would be being slashed by the Heavenly Tribulation right now. Moreover, when Bai Ling advanced to the Tribulation Period, he did not encounter the Heavenly Tribulation when he was in this world, it seems that it is really because the rules of the world are different, and there is no Heavenly Tribulation for cultivators in this world.

In this way, Bai Ling's luck in crossing this time is very good, and he has come to a world of magic rules. Otherwise, the world with other rules, even if it is a technology rule, will have a thunderstorm.

Put away the refined pills, Bai Ling didn't plan to take them now, after all, he could only take three, Bai Ling naturally wouldn't waste it, and when he was taking it in the early stage of advancing to the Heavenly Immortals, maybe three Netherworld Pills would allow Bai Ling to break through to the True Immortal Realm in one fell swoop.

You must know that the level after the earth immortal is very difficult to improve, and with that massive number of faith points, even if Bai Ling has the help of countless saints, he also feels a headache.

If you can use the elixir to improve, it is naturally the best to save faith points. Of course, if you exchange the pill in the system for promotion, it is not much cheaper than directly boosting, so it is best to find medicinal materials by yourself and refine the pill by yourself, so that it can be more cost-effective.

In this case, you need to carefully look for medicinal materials that can increase mana in the world you have traversed, otherwise the speed of strength improvement will be slow.

Fortunately, Bai Ling is now at the peak of the Tribulation, that is, the peak of the Earth Immortal, and his lifespan is almost immortal, and he has a lot of time to improve himself.

After refining the Netherworld Pill, the formation arranged by Bai Ling is useless, Bai Ling collected the arranged formation, and looked at the surrounding many undead creatures blocked by the formation, after all, there are many undead in the undead world, naturally it is impossible to stay in one place, and when they encounter obstacles, these undead who have no spiritual wisdom can only stop here and gather more and more.

These undead who have no spiritual intelligence can't think that this empty place is because of the formation, so they can't get through it at all, because the undead don't consume physical strength, and naturally Bai Ling sees such a scene now. (To be continued......)
