In the mountain behind Xiaojia, a desolate and uninhabited place, under a towering mountain cliff, the noon sun leaves a point of light on the ground through the dense leaves, and the insects and beasts in the forest are all singing, everything seems peaceful and quiet.

"Boom, boom, boom......"

Suddenly, several explosions sounded, breaking the silence around the sky, the dust in the sky, and the huge energy spread to the surroundings, cutting off the towering giant trees around them, and the surrounding area suddenly turned into a barren, and the terrifying energy seemed to destroy everything around!

The earth trembled violently, and the originally towering cliff instantly broke and shattered!

On a high slope a mile away, there were several figures, all stunned when they looked at this huge scene. The only exception is Xiao Yi.

He knew very well that the power of the Silent Xuanlei could cause such a momentum, and he was not surprised at all, at this time, he was standing beside his father Xiao Chengtian, Xiao Zhen and Niu Wu.

After getting the ninety-eight Silent Thunderbolts from the Craftsman's Workshop, Xiao Yi immediately came to this place and began to test the power of the Silent Thunder without further ado.

As soon as Xiao Yi came here, one of them wanted to personally test the power of the Silent Xuan Thunder, and at the same time, this was also a test for his father and Xiao Zhen.

Xiao Chengtian is the head of the Xiao family, many things must be done by him, although Xiao Chengtian trusts Xiao Yi very much, but it is not to the point of blind belief and absolute trust, Xiao Yi needs to prove something in front of him, so that he has enough confidence in himself.

The second is Xiao Zhen, Xiao Zhen is the main person in charge of mining the Situ family's spiritual mine, he must know how to mine the spiritual ore, and the key to mining the spiritual ore is to know how to use the Silent Xuanlei.

The reason why Xiao Yi called Xiao Zhen here is because of this consideration.

As for Niu Wu, it's simpler. Niu Wu is the person in charge of making the Silent Xuan Thunder, and he is responsible for telling Xiao Zhen how to use the Xuan Thunder, which will naturally save a lot of trouble.

Moreover, when Niu Wu learned that Xiao Yi was going to test the power of the Silent Xuan Thunder, Niu Wu took the initiative to follow. After all, Niu Wu also has a lot of credit for making Silent Xuanlei, and the things he worked hard to make are of course because he wants to see his power with his own eyes.

After Xiao Yi's demonstration, Xiao Zhen basically understood how to use the Silent Extinction Thunder, but at this moment, he was still suppressed by the power of the Silent Extinction Thunder, and the power of the Silent Extinction Thunder just now was comparable to the full force of a martial arts master, which was extremely terrifying.

Also suppressed were Xiao Chengtian and Niu Wu, before Xiao Yi said that he would kill all the dozens of people of the Situ family with those powders, Xiao Chengtian didn't believe it at first, but after seeing the situation in front of him, he was not surprised that Xiao Yi was able to kill the killer of the Situ family.

Because the power of this kind of Silent Thunder is really amazing.

The Silent Annihilation Xuan Thunder was made by Niu Wu, and he expected that the power of the Silent Xuan Thunder was already great enough, but seeing the situation in front of him, he still had to admit that he still underestimated the power of these Silent Xuan Thunder.

"What's the matter, father, fourth uncle, do you think the Silent Xuanlei I made can be used to mine the spirit ore outside the city?"

When the dust settled, Xiao Yicai smiled slightly and asked. This question is obviously a bit redundant, if this kind of power can't mine the spirit ore, then what kind of huge power can be used to mine the spirit ore.

The power generated by the explosion just now was comparable to the full force of a martial arts master's blow. The warriors of the Xiao family who are responsible for mining spirit ore are generally warriors at the warrior level, and if a martial artist level martial artist is used to mine spirit ore, although it will be very fast, it is too luxurious to do so.

Moreover, the Xiao family's martial arts masters are really limited, and they really don't have the luxury to the point of mining spirit ore. And if Xiao Yi's Silent Xuanlei is used to mine spirit ore, in other words, it is equivalent to using a martial artist-level powerhouse to mine spirit ore.

It can't help but be so, and the explosion range of the Silent Xuan Thunder is very wide, and the efficiency of mining spirit ore is undoubtedly hundreds of times stronger than that of a martial artist-level master.

"Yes, of course, if none of this is possible, what can be. In my opinion, it is really possible to hollow out the Situ family's large-scale minerals within three months!"

Xiao Chengtian hurriedly responded, with excitement in his eyes, at first Xiao Yi said that he would hollow out the Situ family's large-scale minerals within three months, he thought that Xiao Yi was just joking, but now it seems that Xiao Yi is not joking, he did it.

Of course, what excites Xiao Chengtian the most is not that the Situ family's large minerals can be hollowed out with the Silent Xuanlei, but that with the Silent Xuanlei, the dragon veins under the small valley outside the Xiao family's city can be dug out, which is the real big head.

Xiao Yi is a smart person, and the reason why he drummed up the Xuanlei of Silence was obviously not just for the Situ family's large-scale minerals, but actually for the dragon vein under the Xiao family's small valley outside Qingyun City.

Compared to the dragon veins under the small valley, the Situ family's large-scale minerals are really nothing. In the final analysis, mining the Situ family's large-scale minerals was just an excuse for Xiao Yi to the outside world. Besides, only himself, him, and Xiao Zhen knew about this matter.

We must think of an excuse to cover up this shocking secret, and using the Silent Xuanlei to mine the Situ family's large-scale minerals is undoubtedly the best cover-up, the best excuse.

"The power of this iron ball of Silent Xuanlei is so amazing, with my experience, as long as about thirty, you can dig out all the large minerals of the Situ family, with this Silent Xuanlei, what our Xiao family's descendants need to do is to move the spirit stone out, to the Xiao family, and there is no need to dig it by yourself, which is indeed saving most of the effort!"

Xiao Zhen still didn't recover from the shock just now, his brows were furrowed at this time, there was a hint of joy in his eyes, and he said a little excitedly.

In his heart, he secretly admired Xiao Yi's ability, such a thing, I didn't know that my nephew was made up like this, it was really amazing.

"That's fine. In that case, the matter of mining the Situ family's minerals will be handed over to the fourth uncle! I will give the fourth uncle forty Silent Xuan Thunder here, it should be enough, right?"

When Xiao heard this, he also nodded, Xiao Zhen had also been involved in the Xiao family's minerals before, so he was naturally very familiar with some mineral things, just listen to what he just said.

Besides, Xiao Yi originally planned to hand over this matter to Xiao Zhen, and he had already told Xiao Zhen before that.

Xiao Zhen also nodded unexpectedly.

"Okay, forty is enough! It's just ......"

Xiao Zhen said without thinking, frowning, but he wanted to speak again.

"If the fourth uncle still has any concerns, he might as well say it now!"

Seeing Xiao Zhen's expression, Xiao Yi's brows were also furrowed, and he was a little puzzled.

"I still have some personal matters to discuss with you, I wonder if I can move a little?"

A hint of apology appeared on Xiao Zhen's face, and he was a little embarrassed, and he also realized that he was a little abrupt, but if he didn't raise the question in his heart at this time, he was afraid that he would not have a chance.

"Alright, let's move!"

Xiao Yi looked at Xiao Chengtian's face, and then looked at Niu Wu's face, and saw that it was not the same. Finally made up his mind and spoke.

"It's okay!"

Xiao Chengtian also saw Xiao Yi's embarrassment, smiled indifferently, and spoke. Xiao Zhen said this, it was indeed a little abrupt, but Xiao Chengtian also understood that if it wasn't for something urgent, Xiao Zhen would not have made such an abnormal move.

Xiao Yi didn't speak, but nodded and left Xiao Chengtian dozens of steps away. Xiao Zhen also followed, only to see Xiao Zhen leaning into Xiao Yi's ear and whispering for a while, Xiao Yi also nodded frequently, and after a while, Xiao Zhen left first, such a move really made Xiao Chengtian feel a little confused.

However, since he can tell Xiao Yi, it is estimated that it is not a sensitive matter, maybe it is really just Xiao Zhen's private matter.

After Xiao Zhen left, Xiao Yi returned to Xiao Chengtian's side again, and said: "Father, Uncle Niu still has nothing to do, if there is nothing else, let's do this today!

This is Xiao Yi's plan all along, in order to cope with the upcoming Nine Saints Mountain competition, he must retreat for a period of time and concentrate on improving his strength. After fighting with Qi Ze, Xiao Yi discovered that he had too many shortcomings, and it was just through retreat that he overcame these shortcomings, which was the most important thing.

Of course, what else to do in the retreat is to refine the Breaking Xuandan, which can help the Nine Rank Martial Artists break through to the realm of the Martial Sect, which is the key to improving the overall strength of the Xiao family.

It was the first time for him to refine the Breaking Pill, and he needed an extremely peaceful environment to refine the Breaking Pill, which was very important.

"Great Young Master, there is a request below! I don't know how many materials for making Silent Xuanlei are still in the hands of the eldest young master, I mean the core materials!"

It was Niu Wu who spoke, and Niu Wu Xiao bowed and saluted, and asked quite sincerely.

"Oh, what do you want these materials for?"

Xiao Yi asked with a look of surprise on his face.

"Don't get me wrong, young master, you know that Lao Niu is a craftsman, and he is quite interested in forging a piece. After helping the eldest young master to create the Silent Xuan Thunder, he felt that he could use the materials in the hands of the eldest young master to make even more amazing things. Not only can you mine ore, you can also kill people!"

Niu Wu said, a glimmer of light flashed in his eyes, and his eyes were full of heat. It seems that for forging, Niu Wu is in love with the bones, which can be seen from the expression he spoke.

"If Uncle Niu is just researching, I still have some here, about two catties, I don't know if it's enough?"

Seeing Niu Wu's eagerly looking forward to it, Xiao Yi suddenly had a trace of expectation in his heart, he wanted to know what amazing things Niu Wu could make with the things in his hands.

"Enough is enough, I don't know if the eldest young master can give me some, I'm willing to exchange everything on my body!"

Hearing Xiao Yi say this, Niu Wu was even more excited.

"I don't need to change it, just give it to Uncle Niu, and thank Uncle Niu for helping me create the Silent Xuan Thunder!"

Xiao Yi smiled dumbly and handed a storage bag in his hand to Niu Wu. It can be seen how obsessed Niu Wu is with forging a piece, and in order to get the materials in his hand, he is willing to exchange anything for it.

"That'...... Then I'm welcome, don't worry, young master, I won't let you down! There's nothing to do with me here, I'll go back to the craftsman's workshop now, and I'll study it well!"

Niu Wu held the storage bag in his hand, his eyes were full of joy, he was ecstatic, said goodbye to Xiao Yi and Xiao Chengtian, and couldn't wait to leave.
