There is a very peculiar phenomenon in the cultivation world, that is, many cultivators will build their own caves in certain places, cultivate for a period of time, maybe a few years, maybe hundreds of years, and after leaving, they will often directly close the things they can't use inside, waiting for destined people, which gives many low-level cultivators the opportunity, once they find a remnant cave or place to live, they can gain a lot.

Of course, there are also some cultivator caves, which are destroyed by people, and they will also leave a lot of good things, so there are many people in the cultivation world who like to explore secrets and like to search for the remaining caves.

Generally, cultivators who have sects will also go to explore these, but the main force is not them, but the scattered cultivators who are active in the wilderness, and they are the main force in searching for the remaining caves, because they mainly rely on these to grow quickly.

Mi Xiaojing found a black strip two meters long and a palm wide, one finger thick, leaning against the corner of the wall, of course, with his eyes, he couldn't see through what it was, just curious, and reached out to pick it up.

It was a very heavy thing, and he was heavy in his hand, and he asked curiously, "What is this?"

The guy in the shop was an ordinary mortal, and he said, "This master, this is consigned by someone else, and he wants five low-grade spirit stones......

Mu Xiaoyin was surprised: "Five lower-grade spirit stones, why don't you grab them!"

The guy said helplessly: "This is consignment, you can't bargain, if you want it, just buy it, don't forget it." ”

Mi Xiaojing asked casually, and was just about to put it down, when Wang Weijun suddenly popped out in his mind: "Buy it!"

"The black bar on my hand?"

"Yes, buy it!"

Although Mi Xiaojing didn't understand what this was, Wang Weijun said that he would buy it, and he was tempted, he knew that Wang Weijun's knowledge was much better than his own.

"I want it!"

Mi Xiaojing just had five lower-grade spirit stones, put them directly on the counter, and put the black strips into the storage bag casually.

Although the guy was an ordinary person, he also knew that the person who owned the storage bag must be a rich person among the low-level cultivators, and most of these things were only owned by cultivators in the foundation building period.

Mu Xiaoyin was in a hurry, she said, "Hey, how did you buy it...... What is this?"

"I don't know what ...... is"

Mi Xiaojing said an honest word, but Mu Xiaoyin was stupid, she said: "Oh my God, you don't know what it is, so it took five lower grade spirit stones?

Zhang Ke didn't speak, he always knew that Mi Xiaojing was very smart and wouldn't buy useless things.

Mi Xiaojing smiled: "It's okay, just buy it, I'll study what this thing is when I go home." ”

Mu Xiaoyin opened her mouth, and finally shut up, after all, it was Mi Xiaojing's spirit stone, not hers, and she couldn't help muttering: "What a loser, five spirit stones...... It's a waste......" She was reluctant in her heart, and she couldn't stop Mi Xiaojing, so she had to read it in pieces.

Mi Xiaojing couldn't help laughing, seeing Mu Xiaoyin like this, it was a normal reaction of a girl.

Mu Xiaoyin knew that Mi Xiaojing had just these five low-grade spirit stones, that is to say, Mi Xiaojing had no money, and it was impossible to buy other things, she didn't know that Mi Xiaojing and Lu Yu had reached an agreement, and many things didn't need to be bought.

However, whether it was Mu Xiaoyin, Zhang Ke and Rob, they were all full of curiosity about the black strip that Mi Xiaojing bought, this thing was worth five low-grade spirit stones!

Sitting by the spiritual spring, Mi Xiaojing sat cross-legged, carrying the black strip he bought in the Fang Market on his leg.

"What is this, cost me five spirit stones...... That's all my net worth, and if it's useless, I'll lose a lot. ”

"Stupid...... Will the old man let the things he buy be bad? Five spirit stones...... If you add another thousand spirit stones, you won't be able to buy them!"

"Huh, so good?"

"Of course, will the old man be blind?

Wang Weijun raised his head arrogantly, but unfortunately in Mi Xiaojing's mind, he was an old man in a green robe, no matter how high his head was, it was like this, and he didn't feel it at all.

"But, but what is this?"

"This is a thunder gang wood! It has been refined into a sword blank, but it ...... For some reason, I didn't continue, and I put a simple seal on it. ”

"What is it?"

The sword blank, Mi Xiaojing knew what it was, but Lei Gangmu, he didn't understand it at all.

Wang Weijun has a lot of places to run, of course he knows what Lei Gangmu is.

"That's a specialty of Cloud Thunder Star, there are no other planets at all, that place ...... If you don't have a Dan period, you can't go in at all, and if you go in, you will be killed by thunder, even if it is a cloud thunder star, it is difficult to find Lei Gangmu, especially this Lei Gangmu, which is still a high-grade Lei Gangmu. ”

"This is the best material for refining magic weapons, and if it is placed in the body, it can become a spiritual weapon. ”

That is to say, Lei Gangmu can not only be refined into a magic sword, but also can be further refined into a spirit sword, and generally after cultivating to the Dan period, ordinary cultivators will find a way to get a spirit sword, a spirit weapon and a magic weapon, the power of the two is very different.

Originally, Mi Xiaojing just wanted to find a magic weapon, that is, a magic sword as his weapon, but he didn't expect to get a Lei Gangmu back, and the sword blank was still unfinished, so he was overjoyed.

"How do I unblock it?"

"Four tricks, one spell, you can unseal, you learn it, it's not difficult. ”

Since it's so simple, there's no need to pass it on.

Wang Weijun is a very serious professor, Mi Xiaojing is also very serious about studying, his learning speed is fast, and his understanding is so high, so that Wang Weijun is extremely envious, this person is a genius of cultivation.

Four tricks, one mantra, Mi Xiaojing easily learned, a little review, he completely grasped it, and then said, "I'll try." ”

The change of the mantra, Mi Xiaojing easily sent out, as for the mantra is even easier, you must know that he is a cultivator, and he pays the most attention to the mantra, and the mantra and the mantra are a bit similar, however, one is clear, the other is vague, and he controls this very well.

Mi Xiaojing gently wiped it with his hand, and when his fingers flicked, the last trick completely erased the seal on Lei Gangmu, and in an instant, he heard a crackling sound, and Mi Xiaojing's whole body trembled.

That's when he was electrified, but fortunately, the current is not strong, but he is a little numb all over his body.

Since Mi Xiaojing's hair was scattered and draped over his shoulders, in an instant, his hair stood up, like the head of a mop, and his hair stood on end.

Mi Xiaojing was not the only one sitting around the Lingquan, there were two people sitting around the Lingquan, one Zhang Ke and one radish, and the two of them were frightened when they saw Mi Xiaojing's hair suddenly stand up.

Zhang Ke pointed to Mi Xiaojing: "Ahh......h Head, Hair...... Ahh......h

Mi Xiaojing said inexplicably: "What?"

Rob said: "Hair ...... Stood up...... It's weird!"

At this moment, the seal on the black bar was completely undone, and then everyone saw Lei Gangmu's true face.
