Although Bai Ling is now in the late stage of the Tribulation and has the ability to use space, but without coordinates, if he messes around, he is also likely to get lost in the turbulence of time and space, after all, it is not possible to break through the space-time barriers in any place to be lucky enough to find a world, and it is more likely to be an endless void.

Therefore, a formed spatial passage is still very important, of course, in fact, Bai Ling can also rely on the induction of believers to return to the magic world, but it is not convenient to come back directly.

When he came to the world of the undead, Bai Ling saw the dim sky, as well as the endless death qi around him, as well as the existence of countless low-level undead.

The number of undead in the undead world is countless, and Bai Ling can't see the end at all when he looks at it, but these are some low-level undead who have no spiritual intelligence, if it weren't for the existence of soul fire in the heads of these undead, Bai Ling would think that these are just some bone frames, not some undead.

These low-level undead grew up by devouring each other's soul fire, and slowly formed masters of the undead realm. For example, Golden Skeletron, Lich, Bone Dragon, etc. However, Bai Ling hasn't even seen a high-level undead here, let alone a top-level existence in the undead world.

The area of the undead world is not small, but the environment is too harsh, except for the undead, there are basically some unique plants here, and in addition, there are very few other life. It was a very surprising thing that Bai Ling, a human being, appeared here.

Of course, the undead world is not without humanoid creatures, such as lichs, such as vampires, so Bai Ling has restrained the aura on his body and is not afraid of trouble in this world.

Looking at this endless skeleton of bones, Bai Ling did not have the interest of walking on the ground, but flew in the sky, looking towards the situation below, many undead were calmly absorbing the breath of death there, this is the instinct of the undead, although this is much slower than absorbing the fire of the undead, but these bones without wisdom just rely on instinct.

These low-level undead who have no spiritual intelligence will not attack their kind for no reason, nor can they think of killing the same kind to absorb the fire of the king spirit to evolve, unless they encounter a natural disaster**, a large number of undead will die, and the fire of the undead will appear in front of them, otherwise these unthinking undead will not know how to absorb the fire of the undead.

This leads to the fact that the promotion speed of the undead is very long, maybe for hundreds of years, a low-level undead is lucky not to die, it is possible to become an intermediate undead, at this time the undead have preliminary wisdom, understand the evolution of the same kind, the evolution speed is naturally a lot faster, but it is also a lot more dangerous, after all, you want to devour others, others also want to devour you.

Of course, it is precisely because of this that there are the most low-level undead in the undead realm, and there are a lot fewer upwards. But even so, the undead world is one of the small worlds that humans are very afraid of. After all, the undead are tireless, do not know pain, and are not afraid of death when fighting.

Moreover, there are many undead, and even the bones of the undead after death can form new undead spirits under the nourishment of the qi of death. In the face of such an opponent, human beings will naturally be very guarded, and several invasions of the undead world in human history have had a great impact on the wizarding world, and many human elites have been sacrificed in order to eliminate the undead.

Of course, there are still influences, such as the Valley of the Dead, which is still famous in the wizarding world, isn't it a legacy of the previous war?

Bai Ling is actually very interested in this world, after all, it is a bone shelf, it can move and fight, it is really amazing.

This time Bai Ling's coming to the world of the dead was a complete accident, not planned by Bai Ling himself, but it doesn't matter, after all, after coming here, Bai Ling found that the elixir that had not been refined before could be refined, and Bai Ling had obtained the immortal medicine Nine Phantom Lotus, and originally planned to refine it into an elixir, but the refining conditions were not enough, so it was delayed, but now in the undead world, the power that Bai Ling found was very suitable for refining the Nether Pill.

Now Bai Ling's alchemy technique has long been able to refine the Netherworld Pill, except for the Nine Nether Lotus, the rest of the auxiliary medicines are also very easy to obtain, what is missing is just a refining environment.

The Nether Pill is very demanding on the environment for refining, and it needs to be refined in a place full of death qi. And in such a place, all Bai Ling could think of was the Demon Realm, the Netherworld and other places, but he didn't expect to come to the Undead Realm by accident today to solve this problem.

Although Bai Ling can travel once a week, the crossing address is random, Bai Ling doesn't know if he misses this opportunity, and wants to wait for the next time to reach a place that meets the standard, so he is naturally very interested in this place.

Now that there is a suitable place, it is natural to seize the opportunity to refine the elixir. Bai Ling found a place where the death qi was relatively sufficient, listened to it, and emptied the surrounding undead to make a clearing. Bai Ling plans to refine the Nether Pill here.

The main material of the Netherworld Pill is the petals of the Nine Shadows Lotus, and of course, the other parts of the Nine Shadows Lotus can be refined into different pills.

In particular, the Nine Shades Lotus Seed, refining the Ascending Immortal Pill, can make mortals become immortals. Of course, the Ascension Immortal Pill is not so easy to refine, at least the current Bai Ling does not have the conditions for refining, and can only refine the Netherworld Pill.

However, the effect of the Netherworld Pill is also very rebellious, taking the Netherworld Pill can improve the strength, this kind of pill refined by the Nine Netherworld Lotus is effective for people below the Heavenly Immortal, no one can take up to three, each one improves the strength of one layer, which is a rare treasure for cultivators.

What's even better is that the Netherworld Pill has no side effects, and it is not to stimulate potential to improve strength, which is naturally more popular. Thinking that he was about to refine such an elixir, Bai Ling was also very excited.

Not only can you use the Netherworld Pill, but you can also use it by your own family, but I just don't know how many pills can be formed by refining the Netherworld Pill this time. You must know that even if it is the same material, because of the refining technique, heat, and environment, different numbers of pills will be formed, so Bai Ling still attaches great importance to this refining, after all, Bai Ling also hopes that the more pills he refines, the better.

No one dislikes this kind of treasure. Bai Ling cleaned up the venue and took out his own Dan furnace, there is no earth fire here, but Bai Ling's strength to cross the peak now, he doesn't need earth fire, he can just use his own flame.

Before refining the Netherworld Pill, Bai Ling arranged a formation around it, although there may not be undead to make trouble, but there is nothing wrong with being careful, if you are unlucky enough to meet a powerful undead and come to make trouble when Bai Ling is refining the pill, it will be a failure.
