Lei Yu could clearly feel that even this wall was filled with extremely abundant spiritual energy. It was indeed a good place for cultivation!
Looking forward along the wall that is hundreds of meters long, it is a crystal castle!
Its construction material is the same as the walls. The crystal castle is surrounded by the surrounding walls. Although it is like a birdcage, Lei Yu will not mind even if he is trapped in such a luxurious birdcage.
"Lord Demon King, Lord Lightning."
Lei Yu, who had been carefully observing the building of the Demon King's castle, did not notice that there was a two-headed monster standing not far away from the two of them, but one of the heads could not be lifted up and was lifeless. Lei Yu suddenly panicked.
Surprised, he exclaimed, "You are Xilu!"
"Lord Lightning still remembers me? What an honor!"
Xilu's appearance has not changed at all, it is still the same as before, with thick dark gray skin and strong muscles layered with patterns, giving people a feeling of explosive power, like a snake's head, with something similar to a cow's
There is only one curved horn, and the other one grows on another head, but thanks to Lei Yu, it is impossible for that head to be raised again.
"Of course I remember! I had no choice but to do it, so you don't want a monster!" Although Lei Yu didn't say what he was referring to, the meaning of his words was already clear, and his eyes fell on the lifeless star.
on the head.
"It's been a thousand years, how can I still remember?" Xi Lu grinned with a big, scary smile.
Suddenly, a gloomy wind blew over, and Lei Yu couldn't help but thought, "It's quite gloomy here!"
Although the light is bright, the gusty wind makes people feel uncomfortable.
Niutou smiled and said, "Look carefully around this wall."
Lei Yu looked around. There was a dark red crystal at the top of every two walls. There was one at each corner of the four walls. The dark red crystal was as big as a human head. Lei Yu finally understood why this place was there.
The cold wind whizzes.
Each dark red crystal is surrounded by streaks of light blue gas that are constantly swirling and floating. Those sinister winds are released from this light blue gas. "What is that?" Lei Yu asked.
"Xiaoyu, you should know that there is an item that can be used as currency or money in the world of cultivation, right?"
Lei Yu nodded, "Spars are divided into several types, with different equivalent values."
"Yes, the walls here and the castle you see are all made of spar."
"What!" Lei Yu's scalp was numb and his eyes were wide open. He simply couldn't believe what this bull-headed man said.
"Yes, you heard it right. It is indeed a spar. Although it is an ordinary spar, such a huge quantity is rare." Niutou smiled, obviously he already knew these things very well.
Lei Yu rolled his throat hard, walked to the corner of a wall, and lightly knocked on the wall, making a crisp sound.
Lei Yu put his palms against the wall, closed his eyes slightly, and was suddenly shocked! The wall was filled with extremely pure spiritual energy, and Lei Yu could feel the vastness of it just by touching his hand on the wall!
"It's incredible!" Lei Yu's breathing was no longer even, and his eyes were filled with shock.
Niutou smiled and said, "This is nothing."
"Isn't this nothing?"
"Yes, it's nothing. You should know that crystals are divided into five qualities. The most common ones are white crystals, followed by yellow, blue and purple."
"Yes, I know these, but I haven't found any crystals of other colors!" Lei Yu looked around and found nothing, but the number of ordinary white crystals here alone is already crazy!
"You're ignoring the ground."
Lei Yu rolled his throat hard again and slowly lowered his head. Isn't the ore under his feet the quality of yellow spar?
"What about blue and purple?" Lei Yu asked tremblingly.
The bull-headed big hand pointed to the steps at the entrance of the castle. The steps there were blue on one level and purple on the other, neatly cut and paved there.
"Who the hell gave birth to the demon king here? He is so rich!" Lei Yu couldn't help but cursed.
Niutou and Xilu both laughed, and the former said, "After the demon king disappeared, everything here was buried under the desert. In fact, this was the place where the cultivation world was fighting for it. The so-called fight for the land here was purely an excuse.
We know that a master of demon cultivation in the Mahayana stage will definitely have rare treasures in his hands, but they only know that there are treasures but they don’t know that this is a perfect place for cultivation.”
"No wonder! No wonder!" Lei Yu's heart was beating wildly, no less excited than when he saw Dobel Simi, "I met two friends outside the turbulent star sea, and they were very excited when they saw this spar.
At that time, I thought that this thing was the best thing for practicing, but because of the scarcity, I was reluctant to use it. Then I met two toads in the water and land intersection area on the outskirts of this wilderness. They also said that they could use golden elixirs or crystal crystals.
Stone cultivation is a kind of luxury, I didn't expect it, I didn't expect it! Niutou, you actually have such a good place!"
Being praised is something that everyone enjoys, and the bullhead closed his eyes and grinned, looking intoxicated.
Lei Yu asked, "Why don't you let your subordinates or the demon cultivators in Chengchi and the two major areas come here to practice when there is such a good place? Doesn't their increasing strength mean that your strength has increased?
"Lei Yu was a little confused about this.
The Minotaur shook his head, "No, there are more than tens of thousands of demon cultivators in this southern wilderness area. If the statistics are accurate, it is at least 200,000. For such a huge number of them to come here to practice, it will probably take less than a month.
, the crystal stones here will be completely absorbed."
Lei Yu nodded, "That's it."
"Although this crystal has the ability to regenerate, if it is absorbed completely once, it will not appear again."
"You actually have the ability to regenerate?" Lei Yu was shocked again by Niutou's words.
"Yes, you just saw it. The four dark red crystals are actually blood crystals. The blood crystals must form a pair to have a regenerative effect. There are exactly two pairs in the four corners, which can provide three
It will decrease when five people practice at the same time without decreasing."
Lei Yu has nothing to say. Magical things are often cakes that people envy. There is such a holy place here. If it weren't for Niutou's command, it would have been robbed long ago.
Since two pairs can regenerate, Lei Yu suddenly came up with an idea, "Then if it is split into two by a blood crystal, will it also have the same regeneration effect?"
Lei Yu still remembers the piece of blood crystal he got outside the Riotous Star Sea. He is sure that the fields and karsts will never be willing to use it. If the crystal can be regenerated by dividing it into two, wouldn't it be a karst town?
