Looking in the direction Xiao Ya pointed, I saw that not far away, a white tower about ten zhang high stood quietly under the night.

"Where is it?" Yun Zhan carefully checked the memories in his mind, but no matter what, he couldn't find any memories about that tower, and he couldn't help but curse secretly, he was really a cultivator before, he only knew cultivation wholeheartedly, and he didn't even pay any attention to such a landmark building.

Xiao Ya also seemed to know that Yun Zhan definitely didn't know the origin of this tower, so she explained to him: "A year ago, a swordsmith came to our Black Rock City, and this tower was built by him!"

"Swordsmith?"

"Yes, the swordsmith is amazing! When he came that day, the city lord personally went out of the city to greet him!" Xiao Ya slowed down and said seriously: "The swordsmith is extremely respected, it is said that a sword they cast can increase the strength of sword cultivation by at least one percent!"

"What?" Yun Zhan was taken aback, his strength increased by more than one percent, Shushan is also a sword cultivation inheritance, and naturally there are also people who are responsible for building swords, but the swords they cast are just weapons, and they haven't heard of anything that can increase the strength of the person holding the sword.

"It is said that the swordsmith has mastered something called 'sword pattern', and inlaid them on the sword body can make the sword qi exert stronger!" Xiao Ya said as if she didn't understand.

"Sword pattern, what is that?" Yun Zhan was curious, he was able to make his sword qi stronger!

"I don't know about this!, but I know that a sword inlaid with sword patterns will sell for at least thousands of gold, and ordinary people can't afford it at all!" Although Xiao Ya also cultivates, she is a girl after all, and she has no competitive heart, so far she is only a small blood refining achievement, which is not as good as Yun Zhan, and this kind of thing is also hearsay!

"Thousands of gold!" Yun Zhan was speechless, and said suspiciously: "I am afraid that few people can afford to buy a sword in the poor and remote area of Black Rock City, and thousands of gold!

"I don't know about this!" Xiao Ya shook her head and said, how could they know about such a thing.

As the two spoke, they had already come to the foot of the tower, and when they got closer, the tower looked even more majestic.

"This tower is very strange!" Yun Zhan stood in front of the tower, carefully looked at the tower, and found that the tower was divided into seven floors, and from time to time there would be bursts of heat, which made people feel extremely uncomfortable, as if they were standing in front of a volcano that would erupt at any time.

"Brother!" Xiao Ya walked to a small mound next to the tower, beckoned to Yun Zhan, "Come here!"

"Is this!?" Yun Zhan walked to the small mound and was immediately startled.

I saw that under this small mound, a huge earth pit was artificially dug out, and this mound was probably made of dug up soil.

The length and width of the pit are about ten zhang, but as for how deep it is, it is impossible to see, because the pit is full at the moment, and the pit is full of swords.

"How can there be so many swords here, there must be tens of thousands, let alone tens of thousands!" Yun Zhan looked at the pit full of swords in surprise.

"These are all discarded by that swordsmith!" Xiao Ya pointed to the tower and said, "Every day, a lot of them will be thrown out of it, and it will cause a robbery at the beginning, but there are too many thrown out of it, and the speed of grabbing is not as fast as the speed of throwing it, and it is ......"

"It's all some defective products!" Yun Zhan casually pulled out a few of them from the dirt pit, and found that these swords were either distorted in shape, or they were of inferior quality, and they were obviously failed products, and they were like garbage when thrown here!

"Although they are all defective products, if you look carefully, you can still find a lot of usable ones!" Xiao Ya also came to the edge of the pit and helped Yun Zhan rummage through it.

No way, a really good sword, even if there is no seal carved sword pattern, it must be worth at least hundreds of gold, and now the Yun family can't even eat, and where can they have spare money to buy a sword for Yun Zhan, they can only come to this garbage heap and "Taobao" from it!

It's just that these waste swords that were discarded in the dirt pit have rusted one by one under the sun and rain, but for Yun Zhan, these defective products may not be really good treasures!

"Shhhh

Yun Zhan silently ran the "Ten Thousand Swords Technique", picked up a waste sword, and lightly rested his fingertips on the sword body, and in just an instant, the waste sword in his hand immediately turned into a pile of waste slag.

"Sure enough, it is a defective product, and there is only a trace of the golden sharpness contained in it!" Yun Zhan threw away the bare hilt of the sword in his hand and picked up a waste sword again.

Although the golden sharpness contained in these waste swords is pitiful, it adds up to a lot, and if nearly 10,000 waste swords are devoured, it is still quite impressive!

"Huh!" When Yun Zhan devoured the third waste sword, he suddenly found that in this waste sword, in addition to the sharp energy of gold, it also contained the sharp qi of fire, but the content was so low that if you didn't look carefully, you wouldn't be able to detect it at all!

This fire qi is much less than the golden sharp qi contained in it, but the fire qi is not as thick and low as the golden sharp qi, but it seems to be urgent.

As soon as Fang entered his body, Yun Zhan felt a burning sensation coming from his meridians.

"I didn't expect that among these waste swords, there would be such a precious fire qi!" After Yun Zhan absorbed five more waste swords, he actually absorbed a trace of fire qi in one of them.

But at this moment, a strong heat suddenly came out of the tower on the side, which made people feel extremely uncomfortable.

"It seems that this tower is indeed a little strange!" This heat came and went quickly, and after it completely dissipated, Yun Zhan frowned slightly: "Could it be that this Black Rock City is really built on top of a volcano!?"

But these are not the things that need to be considered in the current cloud war!

"Brother!" Just as Yun Zhan continued to silently devour these waste swords, Xiao Ya on the side called Yun Zhan to go over.

"This is!" Yun Zhan walked to Xiao Ya's side and saw that she was pointing at a sword hilt, which could be seen from the exposed sword body that it was an extremely wide heavy sword, Yun Zhan grabbed the hilt and pulled it out with all his strength.

Although Yun Zhan was born without a dantian, he was already a great achievement in blood refining, and the strength of this physical body was two or three hundred catties, so powerful, it was still so hard, which shows the weight of this sword!

"If you don't say anything, you have to have dozens of catties!" This is a wide and heavy sword that is nearly a meter long, and Yun Zhan must lift it with both hands.

Through the appearance, it can be seen that this is a semi-finished product, without blades and blades, and it can be said to be an iron rod!
