In Pang's magic tank space at this time, the huge calamity cloud was refined by Fang Zheng by one-tenth, and in this magic jar space, it can be said that lightning and thunder roared, and the calamity cloud suspended above his head could split the thunder tribulation at any time. It was also Fang Zheng who turned a blind eye, if he was replaced by other monks, he would not be able to stay for a moment in this magic jar space, for fear that he would be scorched by the thunderstorm.

Fang Zheng advanced to the Jindan Realm, and the space of the magic jar was expanded nearly ten times. The radius is dozens of miles huge, and in the sky above this, a huge cloud of calamity is constantly churning, as if the thunder and lightning can split down at any time. In the past, this magic pot space was filled with extremely rich billowing demonic energy. At this time, this magic jar space was filled with the power of violent thunder, and people seemed to be in a world of thunder. And the rolling demonic qi in the space of the magic pot was condensed in a corner.

"There is pure demonic energy in this magic jar space, and without magic crystals, I can make magic crystals!" Looking at the pure demonic qi that was condensed in a corner of the magic jar space, Fang Zheng was the whim.

This magic crystal, also known as the Demon Spirit Stone or the Demon Yuan Stone, is a spirit stone condensed from pure demonic energy, and it is a unique product of the Demon Realm. And this Tianyuan Continent is tyrannical with demonic energy. Occasionally, there are also magic crystal veins, but the yield is relatively low, which is an indispensable spirit stone for demon cultivation.

This illustrates a point, Demon Cultivator. There are two kinds, one is the monk on the Tianyuan Continent, but the cultivation method is domineering and cruel, hurts the heavens and harmony, and is penetrated into a magic word. And the common spirit stones they use for cultivation are still common, such as the Hehuan Sect, and the exercises they practice are disliked by others, and they are called the Demon Sect. And another kind of demon cultivation is to cultivate the exercises of the demon race. Moreover, it absorbs pure demonic qi, and this kind of demonic cultivation must rely on the demon crystals of the demon realm. They often haunt places with a strong demonic aura, and are cruel and easy to kill. It was disliked by the monks of the Tian Yuan Continent. Such demon cultivation is presented in the form of loose cultivation, and the strength is strong, and those who move will kill people, which is the target of many monks in the Tian Yuan Continent.

To create a magic crystal, Fang Zheng is not talking about playing, but really putting it into action. First of all, Fang Zheng took out a top-grade spirit stone, and used the domineering Dao Sect Technique in his body to devour and absorb the heaven and earth spiritual qi in the spirit stone, and then used the domineering Dao Sect Technique to devour and absorb the pure demonic qi in the space of the magic jar, and used the palm of his hand as a medium to infuse the pure demonic qi into the empty shell of the high-grade spirit stone in his hand.

"Bang!"

I only heard a bang explosion suddenly sounded from the space of the magic jar, and the high-grade spirit stone in Fang Zheng's hand exploded violently, seeing that the magic crystal that was about to take shape exploded violently, if it wasn't for Fang Zheng's fast flash, the exploding forged magic crystal would have been able to hurt him.

"Why did it fail, could it be that there is still a remnant of spiritual energy in this spirit stone, and the two contradict each other, causing an explosion when they are about to be saturated. Looking at the spirit stone debris splashed everywhere, Fang Zheng couldn't help frowning. According to his idea, just change the aura in it, it shouldn't cause an explosion!

Fang Zheng took out a few more top-grade spirit stones, but after experimenting several times, the top-grade spirit stones infused with pure demonic qi exploded violently when they were about to be saturated, which made Fang Zheng puzzled. It was Fang Zheng who was replaced with a low-grade and medium-grade spirit stone, and finally exploded. The difference is that the ability of the explosion of the middle grade spirit stone is not as great as the ability of the explosion of the top grade spirit stone.

"Lower-grade, medium-grade, and high-grade spirit stones are not good, do you need the best spirit stones, but I'm going to get the best spirit stones! "After many experiments, Fang Zheng was a little bored, and he had the intention to try it with the best spirit stone, but he didn't have it in his hand, so he secretly cursed and cursed, and then he flashed out of the magic jar space, he was usually depressed, and it was not suitable for cultivation at all.

When he went out, Fang Zheng removed the prohibition in the house, and then went out to relax and relieve the boredom in his heart.

Walking along the cobblestone path, admiring the beautiful scenery in the courtyard, Fang Zheng sometimes bowed his head and sometimes looked up, thinking about why he had failed. If he wants to experiment with the best spirit stone, he doesn't even think about it, just from the value of the best spirit stone, it is not worth infusing the magic qi to turn it into a magic crystal, assuming that it should be done, it is a bit of an explosive heavenly thing.

The sun is setting in the west, the red burning clouds will dye the sky red, Fang Zheng looks at the sky is a burst of distraction, and the red sunset will shine on Fang Zheng's white cheeks is a piece of red.

"Huh... By the way, spirit stones, spirit stones, why don't I experiment with stones!" Fang Zheng, who had fallen into contemplation, suddenly had a flash of inspiration, thinking of the composition of the spirit stones, they were made of ordinary stones that had been washed and condensed by the spiritual energy in the spiritual veins, and he couldn't help but sigh intimately.

As soon as Fang Zheng's words fell, Fang Zheng was also wandering around without scheming, and with a wave of his hand, a suction force was generated out of thin air, and all the pebbles on the sheep intestine path were absorbed by Fang Zheng and sent into the magic jar space.

Thinking of the method of untying, Fang Zheng could be said to be in a hurry and rushed to his residence and closed the door. The ban was placed, and then he entered the magic jar space. Fang Zheng's eager action was the lead, and the two beautiful maids serving Fang Zheng and the others in the courtyard were timid.

Just as Fang Zheng thought, this spirit stone was buried in a place with abundant spiritual energy all year round, and Fang Zheng used ordinary stones to infuse demonic energy. Experimented once and it worked. As the pure demonic qi was poured into the stone, all the impurities in the stone were discharged, distributing a dark light, which was very tempting, and the magic crystal was successfully made.

The more pure demonic qi is infused, the higher the quality of this spirit stone, and the spirit stones infused by the square are all of the highest grade. It's a pity that the demonic energy in this magic jar space is consumed too much by Fangzheng. After pouring a thousand pieces, he had to stop because the demonic energy was exhausted.

After a tiring night, Fang Zheng did not have the slightest look of exhaustion, but his flesh trembled, and what was lacking in the only beauty was that the impurities discharged from the pebbles when the demonic qi was infused made Fang Zheng disgraced. The body was covered with a thick layer of dust.

When Fang Zheng finished washing up and changed into clean clothes, he thought that it was early the next morning, the sun was high in the sky, and Gu Ming and the others were already waiting outside. A few people chatted casually, and a beautiful maid took it. And the group of six went to the place where the trade fair was held.

Although the usual trading meeting has not yet begun, it can still occupy a good position if you go early, and some low-level monks have even set up stalls in the trading venue, which makes the buyers and sellers very convenient.

The buying and selling venue is located in the hospitality hall of the East Courtyard of the Li Mansion. This hall is large enough to accommodate nearly 10,000 people at the same time. At this time, it was only half an hour before the beginning of the trading meeting.

"Wow! There are so many people! This Li Mansion's thousand-year-old birthday is really prosperous, and so many people have gathered. ”

"Uncle Jun. Uncle Sun, the trade fair has not yet begun. Let's go ahead and have a look! I saw a lot of monks setting up stalls here. As soon as he entered the courtyard of the venue, Na and Gu Ming chattered non-stop and shouted to go to the stall area to have a look.

Around the courtyard, many monks received a number plate from the Li family's patrol team and could set up stalls in this compound to buy and sell, without charging any spirit stone fees, but not to cause trouble, if someone caused an accident in the buying and selling area, they would be expelled from the Li Mansion immediately.

Most of the stalls here are unsatisfactory monks, selling things that they can't use, and they rarely find good things, but there are also some strange things.

"Huh... This stone is a bit like a magic crystal, but how is the distribution of demonic energy so thin?" Walking between the stalls, suddenly a strange black stone aroused Fang Zheng's attention, Fang Zheng couldn't help but sigh when he saw this, and then he asked Admiral Mo Han, who was dressed in a white robe, with thin muscles and a slightly pale face: "This fellow Daoist, how can this stone be sold?"

"This fellow Daoist, are you talking about this Demon Yuan Stone?" The white-clothed young scribe couldn't help but ask Fang Zheng when he heard this.

"Hmm... I'm talking about this magic yuan stone, how to sell this magic yuan stone?"

"One hundred high-grade spirit stones!" White-clothed Admiral Mo Han said with some hesitation when he heard this, this magic yuan stone has been asked by many people, but because the asking price is too high, it has not been negotiated, at this time, seeing Fang Zheng asked, he thought about whether it was time to reduce the price, and he always left it in his own hands, and he was not a demon cultivator, so it was useless.

"I bought a hundred high-grade spirit stones!" Fang Zheng, who was playing with the fist-sized black stone block that was suspected to be a magic yuan stone, didn't want to think about it. "Slow down, this old man of the Demon Yuan Stone has two hundred high-grade spirit stones!" Just as Fang Zheng was about to pay the spirit stone, suddenly a discordant voice suddenly sounded from behind Fang Zheng.

As soon as the somewhat sharp discordant words fell, an old man in brocade dressed in a black reckless robe appeared in front of Fang Zheng and the others, this old man in black had a mediocre face, and belonged to the character who would soon be forgotten if he was lost in the crowd, but his eyes were deep and bright, and he was stared at like this, just like the prey that was targeted by a wolf, and he was uncomfortable.

"This fellow Daoist, this item is the first thing I saw, and I also negotiated the price, just waiting for the payment of the spirit stone to complete the transaction, this fellow Daoist, why do you have to intervene. As soon as he saw that the old man in the black robe intervened sideways to stop Fang Zheng from trading with the young man in white, that Jun Tianyou suddenly couldn't help but make his debut when he saw this.

"Little one, what are you, it's not your right to speak, so stay cool. The black-robed old man glanced at Jun Tianyou, and scolded with a cold voice on his face. Then he said: "I will produce three hundred high-grade spirit stones for this magic crystal." ”
