Walking out of the spatial passage, Xiling Chen appeared in an independent space bound to the Immortal King Palace, this space was very small, but there were a lot of runes and metal devices.

On the metal platform in the central area of this space, there is a suspended cube of metal, the metal is purple, and there are complex runes and patterns carved on it, Xiling Chen said with a smile after seeing this thing: "It turns out to be this, no wonder it can make the Immortal King Hall have so much energy." ”

"Good things, you can put them in Demon King City." Xiao Ling also said.

This is a special synthetic metal, but the important thing is not the metal but the thing inside the metal, the thing in the metal is a kind of thing called the plane primordial stone, which can only appear in large dragon veins, or places where the aura of heaven and earth is particularly strong, and the specific function is to absorb nearby energy, and then refine and release.

The absorbed energy is not absorbed from the main plane, but from other planes, such as the shadow plane and the elemental plane.

There are no pitfalls, it's easy to get.

In fact, there is no need for any traps, because if you want to enter this space, you can only enter through the entrance set up by the Immortal King Palace, the former Immortal King Hall must be guarded by a strong person, and outsiders can't enter, and the reason why Xilingchen can come in is very simple, he is a demigod, and he has mastered the ability of space, and with the concept of Xiaoling being armed, there is naturally no problem to come in.

A few minutes later, Xilingchen appeared in the hall of the Immortal King Palace, Yunyue Yanran and Yang Xiao immediately walked over when they saw Xilingchen appear, Yang Xiao asked even more curiously: "Brother Chen, what treasure have you found?" ”

"There are a lot of first-level and second-level immortal weapons, but it's a pity that they don't suit you."

"It's okay, it's okay. The Ghost Valley is huge, and we will definitely find something better when we go to the four secret realms to explore. Yang Xiao said.

After hearing this, Yun Yue Yanran said, "Husband, there are too many things here, how can we take them away?" ”

"Leave it to Xue'er, wait for her to come over, she is bound to the Demon King City, and she can send the things here to the Demon King City."

"Does Demon King City still have such a function now?" Yang Xiao asked in surprise.

In fact, they have always been very curious, Xue'er said that it was the Demon King, but she did not cause her strength to decline because of leaving the Demon King City, and the Demon King actually left the Demon King City, which is a difficult thing to imagine, ordinary Demon Kings basically will not leave the range where the Demon King City is located, because once they leave, other Demon Kings or monsters can launch attacks on the Demon King City, and a Demon King City without the Demon King is very vulnerable.

After hearing this, Xiling Chen explained with a smile: "She is different from Xue'er, her Demon King City is in a different space, she can summon the Demon King City to any place at any time, or summon the Demon King City to her side from anywhere, and the Demon King City is where she is." ”

"Wow!" Yang Xiao called out in surprise after hearing this.

Yun Yue Yanran was also extremely surprised when she heard this, she didn't expect it to be like this: "Husband, how many people are there in the Demon King City now?" ”

"Not counting Xue'er and Shenxuan, there are three people, a big guy is sitting in the Demon King City, a supreme-level one is cultivating, and there is a legendary-level headless god of death, who has not yet given birth to wisdom, but it is estimated that it will be soon, I found the Demon King City in a very remote place, and then let Xue'er become the Demon King, this Demon King City is seriously damaged, and now it is no different from the ruins." Xilingchen said.

"Then I'll help my husband rebuild the Demon King City!"

"It's so interesting, Brother Chen, I'm with me!" Yang Xiao said.

Xiling Chen said with a smile: "Okay, together, together, but you have to step up your cultivation, it is not so easy to rebuild the Demon King City, we are going to build a force, there will be many enemies." ”

The Nine Ghosts, Xiao Xue, and Shen Xuan came to the hall after searching all the other areas, and seeing Xiao Blood appear, Xiling Chen pointed to the resources in the hall and said: "Put them all away, still the Demon King City Warehouse, these are all the resources we need for development!" ”

Xiao Xue smiled slightly after hearing this, and then began to throw things into the Demon King City in pieces, and when everything was packed into the Demon King City, this expedition to the Immortal King Palace was over.

Leaving the Hall of the Immortal King, the map also disappeared.

Everyone looked at the vast desert, and it was really hard to imagine that they had just left a splendid palace and had received so many good things.

"Husband, let's get out of here and go to the Four Secret Realms." Yun Yue Yanran said.

"Let's go."

The desert is only a very small area of the Ghost Valley, and the really big place is the four secret realms, and there are many opportunities in the four secret realms, it can be said that every time the ghost valley is opened, there will be a large number of low-level undead promoted to high-level undead, and the treasures, exercises, skills, and so on inside are things that are rarely seen outside.

In the secret realm, as long as you get the opportunity, you may let an ordinary undead break through the Supreme, and maybe even let a supreme enter the Great Emperor, everything is possible.

This time, the Xuan Nether Spirit Snake was not summoned, because the Xuan Nether Spirit Snake was too conspicuous, and although there were still many places to explore in the desert, the ancient city and the oasis had already been visited, so it was time to leave.

The way to leave is very simple, it is to find the abandoned town in the desert, there is a teleportation array in the middle of the town, this teleportation array can allow you to leave the ghost valley, and you can also go to the four secret realms.

Four secret realms, four different areas, which are the Graveyard of the Gods, the Thousand Mountains Mine, the Sea of the Dead, and the Land of Bones.

Each area has its own characteristics, and the ghost valley will open every once in a while, these four areas are the most explored places by adventurers, where there are good things, and where there are dangers, basically the undead who come to the ghost valley know.

Through the teleportation array, everyone appeared in an almost dark world, the dark area is very common in the undead plane, and it will not affect everyone, and there is no difference between darkness and daytime for the undead.

Darkness here is darkness, there are no special rules.

"What is this place?" Xi Lingchen asked.

Yun Yue Yanran looked around and said with some uncertainty: "I can't see it for the time being, but it shouldn't be the Sea of the Dead and the Land of White Bones." ”

"It's the Graveyard of the Gods, look here." Nine Ghosts said.

After hearing this, everyone immediately looked in the direction that the Nine Ghosts said, a few kilometers away was a tall mountain, and in the middle of the peak there was a group of ancient buildings surrounded by dead air, this mountain was the symbol of the Tomb of the Gods, because no matter where you were in the Tomb of the Gods, you could see this special mountain.

"This is the Supreme Mountain, you can't go up without the Supreme Level, if you want to enter this mountain, you can only act alone." Yun Yue Yanran explained.

"I don't know much about this place, which of you will lead the way?" Xilingchen said.

After hearing this, the Nine Ghosts said: "I'll lead the way, I've been to the Graveyard of the Gods several times, there are two places that must be visited here, the Soul Mountain and the Gods and Demons Trading Table, as for the other places, it depends on luck, this time I entered the Ghost Valley, just to find a suitable soul stone for the young lady in the Soul Mountain in the Graveyard of the Gods." ”

Xilingchen had no opinion, because he didn't know anything about this place.

No matter what secret realm you enter, it is a random teleportation, and there is no map in any secret realm, because the area here will change randomly, but no matter how it changes, some things will never change, such as the soul mountain and the gods and demons trading table that the nine ghosts said.

It may be difficult to meet other undead in the desert, but it is easy to encounter them in the Four Secret Realms, because there are too many undead who have entered the Four Secret Realms.

Nine ghosts led the way, everyone randomly moved in one direction, she and Xiaoxue both emitted their own breath, so as to avoid unnecessary trouble, the undead plane is a place where the weak eat the strong, if you don't have any power, and you are not strong, you will be devoured by other undead.

In the four secret realms, there are as many legendary powerhouses as dogs, and the supreme powerhouses are all over the place, even the nine ghosts dare not say that they can beat the other supremes who can come here to explore.

The Peak Supreme, the Title Supreme, and even the Great Emperor may exist in the Four Secret Realms.

Exuding their own aura is not a provocation, but a warning, and in addition to exuding their own breath, everyone wears the symbols representing their respective forces, Yun Yue Yanran, Yun'er, and Gu'er all wear the logo of Piaoxiang Pavilion, and Yang Xiao and the Nine Ghosts also wear the logo of the Ghost Villa.

As long as it has a symbol, ordinary forces and strong people will not dare to provoke, at least the other party will not take the initiative to provoke and attack.

If Yunyue Yanran hadn't touched Xilingchen, she might have acted with the team of her own forces, but she had encountered Xilingchen, so she would act with Xilingchen.

Not long after advancing, a huge rectangular building appeared in the field of vision, which looked like the Colosseum, but it was actually the Colosseum, but it was not the monsters that fought in it, but the adventurers themselves.

"This is the gladiatorial arena of the Grim Reaper, anyone can go in and challenge, you need to pay something of a certain value, if not, use your life, if you want to get a reward, you have to fight at least three games in it, there is no reward before the three, only the fourth game will give a reward to the challenger, my amethyst sword was obtained here, before I became the Title Supreme, I fought five times here." Nine Ghosts said proudly.

This is indeed a very proud thing, because the Gladiatorial Arena of Death is the place where an adventurer's combat prowess is measured.

Ordinary adventurers can hold on to two games at most, elite-level ones can hold on to three, and the fourth game is a watershed, and the successful challenge of the fourth game proves that it belongs to the top powerhouse at this level, and the challenge to the fifth game is the title of the strong, and the successful challenge of the sixth game is the peak powerhouse, which is a stronger existence than the title.

As for the seventh and eighth scenes, they rarely appear, at least there have been no such characters in the last two hundred years.

There is no money to challenge, if you don't win three games, there will only be death, but if you pay the money, at least you won't lose your life if you can't fight, but you may be disabled.
