"Well, I remember. ”

Du Feng didn't explain much, but still listened to the old man's advice. By the way, he looked at the big sign on the tower, and saw the new list changes, and Xiaobei's name turned out to be ranked fourth. Okay, it's progressing fast enough. It seems that next time you break through the level, you have to set a new record, otherwise you will be caught up by other girls.

Since the master Hong Xiuzhen said that the disciples of the Yuxian Sect can use the demon clan exercises with their apprentices, it should not be a big problem. The old man who guarded the tower told him this, mainly because he was afraid that he would be too eye-catching. It's right to think about it, Du Feng has only been in the field for a few months, and he has broken two records for Uncle Weber, and many people must be staring at him. If it's not necessary, it's better not to show the demon clan exercises lightly. But when it comes to the safety of your own life, you can't care so much.

After Du Feng left the Sword Tower, he did not go back to his residence directly, but went to the Shuojin Pavilion. He had some contribution points left before, plus what he had earned just now, and he planned to exchange it for some thunder iron. has already said that when there is a chance, I will get Lei Tie for Xiao Hei to eat, and I will do what I say.

"Hehe, I know that Brother Du's words count. ”

Xiao Hei was very happy when he heard that there was thunder iron to eat. You know, that thing is a rarity that money can't buy on the outside. This kind of resource is generally in the hands of a sect with a relatively deep foundation. Even the thunder iron of Yuxian Gate is in limited supply, because those stocks were obtained by the old-timers, and it is difficult to get them now.

"You're going to exchange it for thunder iron, are you sure?"

As a result, when Du Feng proposed to exchange Lei Tie, he was immediately questioned. In fact, he is now a little famous, but the problem is that he doesn't practice thunder attribute exercises, what do you want this thing to do, won't you take it out and sell it. The people of the Shuojin Pavilion are very careful, even the inner disciples are not allowed to sell the sect's Lei Tie for money. If this thing is auctioned on the black market, it can be exchanged for a lot of fairy stones.

"I want to use this sword. ”

In desperation, Du Feng had no choice but to take out his dragon sword and put it directly on the counter. The best innate spirit weapon took the dragon sword, and directly persuaded the staff. They saw that this was not only a high-grade sword, but the key was to continue to grow. Such a good sword is indeed worth feeding with thunder iron.

In order to increase his persuasiveness, Du Feng deliberately showed a little bit of his thunder attribute technique. His hand rested on the dragon sword, and there was immediately a purple arc winding. It is like a small purple dragon swimming, which looks very eye-catching.

"Okay, I misunderstood, so I'll exchange it for you. ”

The staff of the Shuojin Pavilion understood, no wonder Du Feng was able to break Webber's record. It turns out that there is such a good weapon, and it can also invoke the power of thunder and lightning. The lethality of the thunder attribute technique is already very large, and if it is combined with the sword technique of the Feather Immortal Gate, the speed of breaking into the sword tower will naturally be faster. I believe that a person with such a high talent will not go out to sell it with thunder iron. If you have a good thing, of course, you have to use it yourself.

In fact, they were really mistaken, first of all, Du Feng did not rely on the power of thunder and lightning to break into the Sword Tower, and secondly, he was not so noble. If he is really short of money, he is afraid that he will really exchange Lei Tie and sell it on the black market, and it must be auctioned, so the price of selling is high.

However, he is not short of money at present, but he is relatively short of good materials, so he will not sell it after exchanging Lei Tie. This time, the people of the Shuojin Pavilion were quite generous, and the amount of exchange given to him was not small, and all the remaining contribution points were replaced.

"Thank you!"

Du Feng thanked him, loaded the thunder iron and went out. He took these thunder irons, mainly for Xiao Hei to eat. If there is any leftover, give it to the dragon sword. Because taking the dragon sword can also Gengyuan to improve the grade, it doesn't necessarily have to be thunder iron.

"Tut-tut...... Good stuff, I'll eat it first!"

Xiao Hei has been following Du Feng for a long time, and he has also learned his tone. While being polite, he swallowed most of the thunder iron in his stomach. Of course, it doesn't bite with teeth, and Lei Tie can't bite it if it's so hard. Xiao Hei opened his mouth, directly sucked a piece of Lei Tie into his mouth and swallowed it, without chewing the process.

Lei Tie is not so easy to digest. When it finished eating most of it, it couldn't eat, and lay there to digest it slowly. With Xiao Hei's divine beast physique, his stomach was also bulging. It didn't take long for it to fall asleep.

Well, seeing that Xiao Hei had fallen into a deep sleep, Du Feng knew that Lei Tie was not in vain this time. Although it will take a little longer, as long as Xiao Hei wakes up, he will be promoted to the fifteenth level. The remaining small half of Lei Tie was simply used up by the Dragon Sword.

Originally, the sword man didn't expect Du Feng to use such a precious thing as Lei Tie for himself, but it already contained Lei Yuan Power in addition to being metal, which could be of many uses. According to the cost performance, if it is used to upgrade the level of the dragon sword, it is better to use the relatively cheap Gengyuan.

But what Du Feng thought was that since he had already redeemed it, he would use it. Things only make sense when they are used, and they don't make sense to store them there and not use them, no matter how expensive they are.

"Thank you, master!"

The swordsman in the dragon sword was not lightly moved. It was sure that it had followed Du Feng to the Heavenly Realm, and it was the right one. In fact, when the sword man ascends to the heavenly realm, he will be subdued by the warrior and become a sword in someone's hand, and the key is to follow the master.

For example, the sword tower of Yuxian Gate is transformed by a swordsman from another world. It just follows the right master, that's why it can have such great achievements. The sword man is mixed in the heavenly realm, if he only relies on himself, it will definitely not work.

The way to absorb thunder iron by the dragon sword is different from Xiao Hei. It is not eaten, but slowly assimilated. As long as you put the Dragon Sword and Thunder Iron together, the Thunder Iron will gradually blend in, a bit like ice melting into the water.

Tut-tut...... It's really not a mistake to spend money!

Seeing the arc on the dragon sword winding around the Thunder Light Cave, Du Feng couldn't help but sigh that it was good to be rich. To be precise, it's just right to have a contribution point. Because after absorbing those thunder irons with the dragon sword, he was actually promoted from an innate spirit weapon to a magic weapon, and it was also a medium-grade magic weapon.

If it's just an ordinary promotion, it won't have such a strong effect. After all, magic weapons and spiritual weapons are two completely different concepts. It's really because of the thunder yuan power contained in the thunder iron that the dragon sword has undergone a qualitative change. Not only did the swordsman have thunder and lightning on him, but even the giant dragon he was riding on had become a thunder dragon.

Du Feng pondered, maybe next time he could try to create a new supernatural power, it was called Thunder Dragon Attack. The swordsman rode a thunder dragon, and the scene must have been spectacular. Of course, this is just an afterthought, and he is mainly practicing the Flying Shadow Streamer first.
