Mrs. Lan burst into tears after speaking, she never expected that the Lan family would have such a day.

Looking at the spirit wings on the ground that were indiscriminately discarded by the people of the Netherworld Temple, Mrs. Lan's heart ached, these were the treasures of the Lan family, and a pair of spirit wings poured into the countless efforts of the Lan family.

"It turns out that this is the Lan family spirit wing that can be as famous as the Tang Sect Spirit Wing on the rivers and lakes!" The voice of the Burning Instrument Spirit suddenly sounded in Su Yu's heart, although he had always heard about how ingenious the Lan Family's Spirit Wing was in the rivers and lakes before, but because he was in the Tang Gate, the Burning Instrument Spirit did not feel that the Lan Family's Spirit Wing was unique, and the same name as the Tang Sect was just an exaggerated statement by the Jianghu people.

But after seeing the Lan family's spirit wings today, the Burning Instrument Spirit has a new understanding of the Lan Family's Spirit Wing, and today's misfortune of the Lan family makes the Burning Instrument Spirit sigh.

The Lan family's spiritual wings are famous in the rivers and lakes, but they never thought that if they suffered such a catastrophe today, if it were not for the favor of God, they were afraid that the Lan family's spiritual wings would disappear from the rivers and lakes.

"Ancestor of the Instrument Spirit, is this Spirit Wing the key to turning the defeat of the Race into victory when it fought with the Demon Clan thousands of years ago? Why have I never heard of the Ancestor mentioning it before?" Su Yu heard the exclamation of the Burning Instrument Spirit, and then he remembered the matter of the Spirit Wing.

"Yes, a thousand years ago, the key thing that turned the human race into victory was the spirit wing! At that time, the demon army not only had demon beasts on land, but also demon beasts flying in the air, and the strength of the human race at that time was far less powerful than it is now, and there were very few people who could fight in the air. ”

The thoughts of the Burning Vessel Spirit flew to the time of the war between the two races thousands of years ago, and the tragedy of the war at that time seemed to be still vivid, and the current Terran must not have imagined how precarious the situation of the Terran was at that time!

The human race is losing and retreating in the hands of the flying demon beasts, but there are not many masters who can fight with the flying demon beasts in the air, the situation at that time is not only the interference of the flying demon beasts, but also to hold the demon beast army on the land, the human army and the demon clan are fighting extremely hard!

"At that time, the human race had no way out, so they could only face the difficulties and try their best to solve the flying demon beasts, so the Tang Sect developed the spirit wing!"

"The spirit wings developed by the Tang Sect only need to consume spiritual power, and they can fly in the air at will, no matter what strength realm people are, as long as the spiritual power in their bodies is enough, they can activate the spirit wings to fly in the air, and the great war at that time was precisely because of the spirit wings, and the human race gradually reversed the disadvantage in the air. "The Burning Instrument Spirit told Su Yu about the important role that Spirit Wings played in the war between the two clans thousands of years ago!

"I see, the senior who developed the spirit wing is really amazing!" Su Yu looked at the spirit wing in his hand, and a sense of awe inexplicably arose in his heart.

Thousands of years ago, the human race was still weak, but it still relied on this wisdom and hard work to lay down this territory, I have to say, the spirit wing did occupy a lot of credit.

"That's true!" As soon as he thought of the scene of that day, a burst of pride unconsciously rose in the heart of the Sacrificial Instrument Spirit! Especially the Tang Sect Elder who developed the Spirit Wing, he was really heroic!

"Senior, there is one thing that Su Yu still doesn't understand, since the spirit wings are so outstanding and very useful, why don't you see many people with spirit wings now?" Su Yu was a little puzzled.

According to the Burning Instrument Spirit, the Spirit Wing should be very respected among the human race, after all, there are not many people who can rely on their own strength to achieve volleys, and even fewer people like Su Yu who can do whatever they want with the sword, because there are not many people's swords that can be like Su Yu, and they will not be destroyed because of the sword many times.

And the spirit wing is so against the sky, as long as the spirit power is abundant, he can fly all the time, Su Yu feels that the spirit wing, a thing that can fly at will, should be highly respected in the human race, but the current facts are far from what Su Yu thought, at least after he came out of the Tang Sect for so long, he has never seen a person with a spirit wing flying in the air.

"Hehe, you don't understand this, although the spirit wings have the ability to defy the sky, but that kind of loss is not something that ordinary people can squander, and a pair of spirit wings often costs a huge amount to get their hands, and they can even be auctioned at auction for a sky-high price!"

"And this, but it's only enough to get a pair of spirit wings, the higher the grade of the spirit wing, the higher the price, and its quality is not a problem, and the price of the spirit wing, the grade is naturally low, but the wear is very high, ordinary people absolutely can't afford it!"

"So it's because of this!" Su Yu suddenly realized, if it was because of the huge loss, he could explain why the spirit wings were so rare now.

"In fact, thousands of years ago, spirit wings were not scarce, and because of the war with the demon clan, almost everyone who reached the spirit pill realm had a pair of spirit wings, and the materials for making spirit wings were originally taken from flying demon beasts, so the spirit wings made by the Tang Sect were given to those masters who participated in the war for free, and all the spirit wings that were worn out in the war were quickly repaired with the hairy bones of the flying demon beasts, unless the spirit wings were seriously damaged, they would be discarded. "The Sacrificial Vessel Spirit told me about the Spirit Wing, it was a very long time ago.

"Then since it was not difficult to make spirit wings at that time, and it was not troublesome to repair the worn spirit wings, why are the spirit wings so precious now?" Su Yu still didn't understand very well, it was easy to understand that the spirit wings were made from flying demon beasts, after all, spirit wings were flying things, and it was expected to be made with things on flying demon beasts.

"You still don't know, the production materials of the spirit wing are very scarce, only one kind of divine bird on the Tianling feather is the best material for making the spirit wing, and that kind of divine bird was rare after all thousands of years ago, and now it is even rarer, and the repair of the wear and tear of the spirit wing also needs to use this Tianling feather, so down, the cost of a pair of spirit wings is even more expensive, the person who can buy the spirit wing may not have the financial resources to repair the worn spirit wings, and he is not able to get this heavenly feather if he has the financial resources!"

"The most important point is that not everyone can make spirit wings, first, it depends on strength, second, it depends on talent, and third, it depends on becoming a refiner! Making spirit wings is the same as refining weapons, only a refiner can perceive the subtlety of it, even if it is just a trace of error, the actual effect of a pair of spirit wings will be greatly reduced!"

After the spirit of the sacrificial instrument finished speaking very seriously, after such an analysis, Su Yu finally understood why he couldn't see anyone flying in the air with spirit wings now.

"Actually, there are a lot of people who have spirit wings now, but before you have not come into contact with that level, it is difficult to see, everyone who has spirit wings can make the rivers and lakes tremble, and most of them are the children of the hidden family and the gate faction, it is not an exaggeration to call it the dragon and phoenix among the people, when you return to the Tang Gate, you will understand if you can contact that level in the future. ”
