The Undead City is not a city built by humans, but a city excavated by human miners from underground ore veins. In the beginning, the grimace of the Immortal King City had its mouth, nostrils, eyes, and ears occluded. At that time, people rushed to settle down and cultivate here because of the concentration of magic in the Immortal King City that was much higher than that of the outside world. With the increasing population of the Immortal King City, rows of crowded residences gradually appeared on top of the originally smooth ghost face, as if a well-established face had turned into a pockmarked face in a few years.

In this regard, people who want to improve their magic cultivation faster do not care. In fact, because of the abundance of magic in the Immortal King City, the land in the Immortal King City is constantly improving. It is precisely because of this that the bungalows in the Immortal King City have gradually become buildings, and the price of land is also increasing day by day.

It's just that in the process of the Immortal King City's continuous prosperity day by day, the first group of people to enter the Immortal King City found something that made them happy. That is, although the rocks at the foot of the Immortal King City are difficult to excavate, the further down you dig, the more abundant the magic beneath becomes. So, in order to strive for a better cultivation environment, people came to the vicinity of the eye socket of the ghost face at the lowest altitude in the Immortal King City, and began to dig the rock at the location of the "eyelid" of the ghost face in the Immortal King City, trying to dig a passage to the depths.

With the unremitting efforts of the people, after several years of excavation, the people finally dug a passage to the deeper underground at the eye socket of the Immortal King City, and dug the passage all the way to the secret space hundreds of meters underground in the Immortal King City!

Looking down at the "mouth" under his feet, which had already revealed hideous "sharp teeth", Zuo Zhe had already foreseen the end of this group of "little experts in death".

Sure enough, after the people had worked hard to dig through the underground passage, the seal in the Immortal King City was finally broken by the people! Although the seal only broke a gap, the Immortal King City, which was originally peaceful and could be called a holy place for cultivation, turned into a terrifying Shura ghost in one day!

Along with the cracks of the seal, the originally closed mouth, nostrils, eyes, and ear canals on the ghost terrain of the Immortal King City, the sky-rushing demonic qi broke through all the obstacles and quickly filled the entire Immortal King City, allowing the Immortal King City to quickly transform in the direction of the Paradise of the Dead in a strong earthquake!

Because of the rupture of the underground seal of the Immortal King City, except for a very few lucky people, almost all people and most of the animals in the Immortal King City have become undead creatures under the erosion of demonic energy!

However, the changes in the Immortal King City are far from stopping. Those creatures that were transformed into undead spirits because of the demonic qi, due to the influence of the underground demonic qi, converged in the direction of the mouth, nostrils, eyes, and ear canals of the immortal king's city, and continued to strengthen under the nourishment of the demonic qi. And in the battle between the undead creatures because of the competition for a better position, the combat power and combat experience of the undead creatures have also been strengthened step by step. According to the Lich Immortal, those undead creatures closest to the "Feng Shui Treasure Land" are also being attracted by the demonic energy and digging deeper into the underground of the Undead King City!

"Demonic Qi, aren't we also in danger?" Zuo Zhe asked worriedly. If it weren't for the DIY ability, Zuo Zhe would have wanted to make himself a gas mask.

In fact, after so many years, the remaining demonic qi in the air of the Immortal King City had almost been absorbed by the undead creatures in the Immortal King City, and only deadly germs were left in the air. And with the priest's healing and dispersal skills, Zuo Zhe didn't need to worry about suffering from illness as long as he wasn't preparing to live permanently in the Immortal King City.

According to the Lich Immortal, the closer you get to the Ghost Face's mouth, nostrils, eyes, and ear canals, the stronger the undead will become. However, the position of the mouth of the Immortal King City was different from the others. Because the mouth of the ghost face of the Immortal King City is relatively huge, the demonic energy released is also the thinnest. Therefore, compared to other places, although there were the most undead creatures in the mouth of the undead King City, the strength of these undead creatures was the lowest on average.

Zuo Zhe had no interest in going deep into the Immortal King City, and what Zuo Zhe wanted most to do was to quickly lead people out of this damn place. If too much time is wasted in the Immortal King City, Zuo Zhe's previous arrangements in the Golden Town and the Gold Mine will probably be in vain! At that time, relying only on a hero of the Paladin and ten Terran infantry, with eight thousand slaves, will not be able to stop the army of the slave owner Grand Duke from sweeping out!

So, the conversation finally got back to square one, and that was the method that the Lich Immortal had been researching in recent years to escape from the Immortal King's City. According to the Lich Immortal, there are two ways to leave the Immortal City. The first option is to dig a passage through the mine that collapsed during the previous earthquake. It's just that the Immortal King City is located thousands of meters below the surface, and it is not easy to dig through. To be honest, if it weren't for the fact that undead creatures such as skeletons and zombies didn't need to breathe oxygen, and there was still air circulation between the undead city and the surface, the undead city would have no way for people to breathe at this time.

Trying to dig a channel is a time-consuming and big project even for Terran farmers who are professional in mining. After all, it takes a long time to climb even a mountain with a height of several thousand meters, let alone dig a hole thousands of meters above the ground. The distance of the mine to be dug is definitely far more than tens of thousands of meters!

"If it's just a passage, then even if it's difficult, it's going to be dug through. The Lich Immortal shook his head and said, "The real difficulty is the monsters that have mutated under the attack of demonic energy, like the vine monsters you encountered before. Because the rocks of the mine are relatively loose, it is convenient for the demonic energy to leak outward, and the area near the original mine road has become a gathering place for vine monsters and underground alienated creatures. ”

Therefore, the idea of digging a hole to dig a road to heaven may be difficult to realize. Then, it's time to talk about the second way to escape. The second way to escape is to use the teleportation circle to escape!

If it was just an ordinary teleportation circle that could escape from the Immortal King City, the Lich Immortal who had studied the spatial teleportation spell for thousands of years would have teleported away long ago. It is not difficult to learn the teleportation spell, and it is not difficult to locate the teleportation target, but the real difficulty is how to eliminate spatial interference! Since the crack appeared in the underground seal of the Immortal King City, the space around the Immortal King City has been strongly distorted. I didn't feel anything in the confines of the Immortal King City. But if you want to get out of this area, you will encounter a desperate bondage! It seems that because of the crack in the underground seal of the Immortal King City, the second seal of the Immortal King City was inspired. And the characteristic of this second seal is that you are allowed to enter but not to leave!
