Blood crystal is a naturally formed precious ore, and it is also one of the few carriers in the world that can carry spells. If you engrave the spell in the blood crystal, it can be stored for a long time and will not disappear due to the change of time. However, the generation of blood crystals is extremely difficult, in addition to the pressure that reaches ten thousand feet deep underground, it must also be irrigated by the essence blood of foreign beasts or humans, and it will last forever to stimulate the spirituality of the ore and become a blood crystal that is unique in ten thousand.

Due to the harsh conditions, the few remaining pieces of blood crystals on the market have been sold at sky-high prices, and the blood crystals can not only be used as a carrier of spells, but also can be used as precious ores, integrated into weapons, which can make weapons produce incredible power and even stimulate the spirituality of weapons. Legend has it that the eldest grandson, Changkong, once stole a dagger made of blood crystals, but he was never seen to use it. And the Black Emperor also collected a fist-sized blood crystal, which was hidden in the secret compartment of the room, and even Ji Yunkong was not allowed to see it.

As far as the two of them knew, the Black Emperor's fist-sized blood crystal was already a unique existence in the world, but compared to the current piece under Ji Yunkong's feet, it could be said to be unsightly. The piece under his feet alone was at least the size of a bathtub, and looking at its surroundings, it was still covered with deep soil, and it was only the tip of the iceberg that was obviously dug out by Ji Yunkong.

"Wow" Emperor Yan was even more excited than Ji Yunkonglai, jumped down with a dodge, and immediately used his magical powers to start digging. The attraction of blood crystals to her was much greater than that of Ji Yunkong.

Countless flames formed big hands, and the hard earth melted under their heat, and then was ruthlessly lifted, and with spells, it was more convenient than martial arts to do something in life. Ji Yunkong gradually couldn't stand the heat anymore, however, the surrounding scene attracted his attention.

Blood Crystals! Blood Crystals! It's still blood crystals! Countless blood crystals poured out from the ground, as if they were the true face of the earth, and the surface of the earth was nothing more than a carpet spread on them.

"This ...... What's going on? Emperor Yan also stopped the spell in her hand, she was already completely shocked by the scene in front of her. Every inch of blood crystal was engraved with hundreds of spell marks, connected to each other, and it was an incomparably large spell.

"Now you understand? This entire valley is made of blood crystals, and this land is where they supervise prisoners and control all spells, and every inch of land is an incomparably exquisite spell. Do you know why heavenly spells can't destroy everything on earth? It's because it's where their strength comes from. Now that I think about it, the reason why I was able to use the Demon Fear Formation to resist the sky spell was not because I had the ability to resist, but because the Demon Fear happened to cause the power of the underground. Ji Yunkong's voice trembled a little.

Although he had been prepared in his heart, when he heard Ji Yunkong's conclusion, Emperor Yan almost fainted. What kind of great trick did the ancient spell masters lay here? Replaced all the land in the valley with blood crystals! Is it just a prison? How many blood crystals are buried here, all the blood crystals of tens of thousands of years together throughout the ages are not as many as here.

Wrong! It is absolutely impossible to do so, precisely because ancient times were the most developed era of spells, and the demand for blood crystals by spell masters must be much stronger than now. How can such a scarce resource be wasted here? Emperor Yan shook his head and forced himself to calm down. This calmness, sure enough, found the difference, although these blood crystals look the same as the blood crystals, but the curse seals inside are pitiful, Emperor Yan remembers that the Black Emperor's blood crystal, there are enough to store tens of thousands of spell marks, and the blood crystals of the same size here can store a thousand is already good.

"Really?" Emperor Yan resounded a lost craft recorded in ancient wild history.

Ji Yunkong gave him the answer in an instant: "That's right, these blood crystals seem to be artificially made. ”

As he spoke, Ji Yunkong swiped his hand on the blood crystal, and the golden light flashed, and a spell disappeared. "Go back to the original", this is a spell used by officials in ancient times to solve crimes, which can find the final essence from a part of things, which is not powerful, but very practical.

"You want to find the source here?" Emperor Yan asked.

Ji Yunkong smiled: "You know that blood crystals can be artificial, but do you know how it is made?" ”

Emperor Yan shook her head, because the artificial blood crystal was far inferior to the real blood crystal, and the partial birth was very expensive, so she didn't care too much about it at that time.

Ji Yunkong said: "I once tried, I had to use a piece of ore as precious as blood crystals, such as purple gold, cold ice black iron, thousand-year-old black steel, etc., and then wrap them with the powder ground from real blood crystals, and then mix them with the blood of humans or foreign beasts, and bury them underground for several years before they can succeed." Of course, the higher the martial arts of the master of the essence blood, the better, and the stronger the bloodline of the alien beast, the better. ”

Emperor Yan was speechless, so it is so, no wonder this kind of craft will be lost, although the time for the formation of blood crystals has been greatly shortened, but the value of purple gold and other things is not weaker than blood crystals, and the ability of man-made blood crystals is far inferior to natural formation, it can be said that the gains outweigh the losses, if it goes on like this, how can anyone be so stupid as to be so wasteful.

Ji Yunkong continued: "I also tried to make one back then, using a small piece of purple gold, and secretly scraped a little powder from the black emperor's piece of blood crystal, as for the blood, I finally asked for it from the old man. I remember as if I had buried it by the river, but then I left and never had a chance to go back. ”

"You're called a defector!" Emperor Yan corrected mercilessly.

Ji Yunkong rolled his eyes, looking helpless.

At the same time, next to a certain stream in the Tang Empire, a huge explosion suddenly sounded, shaking the woods next to it.

"His grandmother's!" The voice of the White Emperor came from the river, "Which bastard who killed a thousand knives buried the blood crystal in the riverbed, and carved an explosive spell in it!" Oh my God, no, old yellow, old black! Help! ”

In the curse valley, Emperor Yan smiled slightly and said, "Let's go, after a while, 'go back to the original' and disappear again." ”

Ji Yunkong followed behind him with a depressed face.

Luoyang City.

Helian Jun looked at Ying Yuewen in front of him in a daze, and the words he just said sounded in his head like a roar: "Brother Li, Miss came to look for you, I already know, she is right, my parents died when I was a child, and the old city lord picked me up and raised me." As for marrying Miss, it is also a matter of urgency, and I can guarantee you that I have never done anything beyond the norm to Miss. Grant Miss's request and take her away. Luoyang is a dangerous place, even if the two sons do not have the intention of harming the young lady, the court may not be willing to be lonely. Brother Li, I hope Miss Chengquan is infatuated. ”

Helian Jun looked dizzy on the surface, but he was already sneering in his heart, hehe, his wife just came, did his husband come again? You're too anxious, aren't you? What is it that makes you so "warm-hearted" to me? Interesting, I don't know why, but it's always good to cause you a little bit of trouble
