It took more than half an hour to break the ground under the corpses of several angels by the rich dead air, especially the corpses were completely covered with a layer of dead gray frost. However, when the dead ice gas invaded the corpses of those angels, it suddenly repelled like a magnet, and the King of Dead Bone tried every means and could not enter.

The dead bones that awaken the soul will naturally not forget the dead spell of the undead spell. Even a few monster bone beasts that died in unknown times under the ground broke out and appeared in front of them, but the angel did not react at all.

After spending more than half an hour, the King of Dead Bone had to give up on his performance. He looked at Li Junshan awkwardly.

"Okay, it seems that their souls have returned to the embrace of the God of Light." Li Junshan said helplessly, and waved his hand and took back the completely frozen corpse's space ring.

"Sir, I'm asking you for something." The King of Dead Bone changed the subject and said mysteriously: "I think we have found the reason for the existence of that magic crystal vein."

"Hmm?" Li Junshan was stunned and then said wonderingly: "What's the reason?"

"I found some strange things under the magic crystal stone ore vein, and I think you will be interested." The dry bones were rarely kept in a silence.

"How to say it?" Li Junshan was a little moved, but when he thought that the demon invasion was right in front of him, he felt a little inseparable.

The King of Dead Bone said a few words, and Li Junshan was a little surprised when he heard this. He thought for a while and asked, "How many undead lords are there in total?"

"In addition, there are twenty-seven I brought back." The King of Dead Bone answered quickly.

"Twenty-seven plus so many army, as well as the help of the sea clan and orcs, I think I can handle some demons." Li Junshan was a little unsure. After thinking about it, he simply released Da Hei Xiao Hei and ordered Da Hei to guard Xiali City and the Elf Garden.

Xiao Hei's dragon language magic has been completed. During the spiritual exchange, Li Junshan gave Da Hei a few more instructions, and hurriedly flew into the crack of the space with the King of Dead Bone.

The space crack was slowly closing, and the big black spread its wings had not left yet, a group of elves walked out of the forest, but Lu Yi finally couldn't help but come to find Li Junshan.

Because Li Junshan did not deliberately explain, Wallace did not hide the angel's affairs. Lu Yi waited for most of the day but did not see Li Junshan come back, and finally couldn't help but come to ask.

Da Hei Piao looked at them in the air, but he also humanized the romance of the dark swamp. The order it received was very simple, that is, when the demon army had abnormal movements, he went to Polo City to find Xiao Hei through the magic teleportation array, and the latter would send the message to Li Junshan in time in the shortest time.

"Where have you been?" Lu Yi looked at the still fluctuating space.

"Sir, he should have something important to do, otherwise he would never leave now at such an urgent moment." Wallace said softly.

"Yeah." Lu Yi responded lightly, her brows frowned slightly, and she thought to herself: "The demons have launched a large-scale invasion, and the angels have also appeared. The Yalan Continent is now lively..."

As Wallace said, if it wasn't a big deal, Li Junshan would definitely not have left at such a time.

Li Junshan has always had some questions about how those magic crystals were formed, and even discussed with the King of Dead Bones several times but did not draw a conclusion. There are many low-level magic crystal veins, and there are almost all places where the elements of heaven and earth are richer, but high-level ones are only accessible but not to ask for it. What's more, the magic crystal veins that are astonishingly deep and horizontal in the Undead Plane World are now. Although the number of level nine magic crystals is extremely rare, the level eight has mined more than ten thousand.

Putting aside the large number of low-level crystals, these more than 10,000 level eight crystals are equivalent to obtaining more than 10,000 monsters. Not to mention that the hunting process is not easy for people in this world. Even this number is terrifying enough. The preciousness of this magic crystal ore vein can be imagined.

As the King of Dead Bones said, when Li Junshan appeared in Boluo City from the crack in the space, Boluo City, which had already become a forbidden area for life, completely turned into a paradise for undead creatures. Outside the city, it was even more obvious that there were skeletons occupying the main army of undead, just like an ocean of skeletons.

Teams of undead creatures were still teleporting to this side through the undead plane passage. After Li Junshan and the others came from the plane passage to the undead plane, they also saw a large army of undead, standing in the air and looking around. However, there were still teams of undead creatures walking towards the plane passage.

"Ten undead lords are recruiting those little lords and more undead creatures everywhere..." The King of Dead Bone said: "I expect it will take a few more days. Adding Polo City to the extreme southern desert here, the undead creatures alone can definitely reach a terrifying number."

"Yes." Li Junshan nodded, and hurriedly entered the cracks in Xiao Hei's space.

Just a few days after I came to the Magic Crystal Minerals last time, magic crystals like hills piled up on the flat ground outside the mine. The dazzling and blurry light reflected half of the sky with a dreamy and bizarre color.

The magic crystal veins have now been dug to the most spacious place in the horizontal direction. In the words of the King of Dead Bone, it is almost unnecessary to separate from the gravel and gravel. If you dig it down, you will find a handful of crystals.

When Li Junshan had something in mind, he didn't care about looking at the magic crystals, and then walked down the mine under the leadership of Rofute and Death Knight Adrie.

"call!"

The corpse dragon Farrell flew over to say hello to the Holy Land, Xiao Hei glared at it as if he was repulsive and began to chant spells to teleport back to the undead plane passage. Farrell fell down a little disappointedly, stretched out his hand and dragon claws to boredom to fiddle with the magic crystal.

The excavation of the mine is very humane. Perhaps it is for the sake of transporting crystals outwards, the slope excavated is quite flat. In order to welcome the arrival of the Holy Land, a skeleton or zombie holds a high crystal illumination every ten or twenty meters, which doesn't seem very dim.

"No special thing happened, right?" Li Junshan walked along the mine and couldn't help but turn his head and ask Luo Fute, the lich in charge.

"We have always been a little curious about the formation of this magic crystal vein, so I have given orders to the undead who are digging and mining. Once any abnormality is found during the mining process, you must not move arbitrarily." Luo Fute humbly bowed behind Li Junshan and whispered: "After discovering that thing, we temporarily stopped mining and wait for the lord and the king to come back to decide."

"You're doing it very well." Li Junshan nodded in praise and said, "If the matter here is solved and you can go back with me if it's okay. Now you are going to fight with the demons. There are too many undead troops, and you need a few people who can do things to coordinate."

"Thank you, sir." Luo Futt showed a hint of joy in his senses, but he said appropriately: "Sir and the king need me there, and I will do my best to share the worries of the adults."

While speaking, Li Junshan and his group walked out along the gentle slopes that were turning around. There were countless undead creatures in the well-connected mine caves standing still like an eternal existence, but were waiting for the order to continue mining or go out.

After walking for about ten minutes, a blurred color suddenly appeared in front of the sharp mine cave, which was illuminated by the white crystal core. The mine cave was blocked by a semi-clear crystal stone full of various colors. Li Junshan could fully feel the chaotic and powerful elemental power in the mine cave.

"Here..." Luo Fute took two steps and pointed to a path mined beside the crystal mine, and said, "You can see it if you enter here for only a dozen meters."

Walked through a path surrounded by magic crystals, only about ten meters, and after turning a corner, I suddenly realized that Li Junshan had described it briefly from the King of Dead Bones before. When he saw the scene in front of him, Li Junshan was shocked.

A wide giant cave appeared in front of me. The surrounding cave walls and ceilings were filled with magic crystals of various shapes. There was no need for torches and sunlight. These crystals emitting dazzling light reflected the huge cave into a dazzling and blurred state.

There is a building in the middle of the cave, a building that looks familiar to Li Junshan, just like the "pyramid" he saw in various media in his previous life. From a distance, I don't know what kind of metal or mineral it is, the stair pyramid is four or five hundred meters high.

Each staircase or every exterior wall is carved with exquisite decorative patterns, and the tall and majestic golden step-shaped pyramid reflects dreamy colors under the reflection of various crystals. All of this made the shocked Li Junshan feel unreal.

Although it is somewhat different from the pyramids in my memory, Li Junshan is definitely sure that the huge architectural style in front of him is exactly the same as the pyramids he saw in his previous life.

"What's this?"

"So anyone has seen you?"

"Why is this in the magic crystal vein?"

Li Junshan murmured nervously, but the King of Dust Bones and Luo Fute shook their heads together. It was obvious that it was the first time they had seen a building of this style.

"There is a powerful force in it..." The King of Dead Bone did not understand why the adults were so shocked when they saw this building. He pointed to the circular arch below the pyramid with a serious expression and said, "I can't tell which elemental force it should belong to, but it is very powerful."

"Is this a coincidence or something?" Li Junshan's mind buzzed. He had not heard what the King of Dead Bone was saying clearly. Scenes of his past and present life came in his mind like montage scenes. The nerves that had always thought that he was tough enough almost collapsed in an instant.
