"They went in, and they went up to the second floor. Just as Duan Ling and Xiao Pan were selecting items in the secret house, on the small building next to the secret house, a middle-aged man with a pockmarked face said to a handsome young man who was tasting wine at this time.

"On the second floor, it looks like two fat sheep. Mazi, if it is a bumper harvest this time, I will definitely remember your first merit. The delicate young man's eyes flashed brightly, and he said happily.

"Thank you, Childe, thank you. Mazi kept nodding on the side.

"But are you sure they're from outside the stars, and though there aren't many people in this glass star that can scare me, I don't want to cause any trouble. The handsome man asked very cautiously.

"Don't worry, Childe, I have confirmed to the guests who have stayed with them in the restaurant that those two people are indeed from outside the Glass Star, and they have no background in the Glass Star. Mazi assured in a firm tone.

"That's good, this is a good opportunity to make a fortune, and then went to the teleportation array, and went to the rich building of the secret house, and the spirit stones on these two people are also above tens of millions. You keep an eye on them, and keep you informed of any moves. After finishing speaking, the young man threw a storage bag on the table and slowly walked downstairs.

Mazi sent him away respectfully, grabbed the storage bag and opened it quickly, his eyes suddenly flashed, and there were hundreds of spirit stones stacked in the storage bag.

In the Vault......

"What is the origin of this rusty black iron, why is it sold at such a high price?" Duan Ling asked the beautiful maid who was still embarrassed on the side.

Such a thing, placed among the rare treasures on the second floor, must have been seen by many people. And the price is outrageously high, if it is not really different, it is a means played by merchants.

After all, the price is so high, which in itself gives it a great sense of mystery. Although most people can't see anything at all, what if you meet some wealthy people who want to buy it back and study it?

"This piece of black iron, from a dangerous realm, was obtained from the corpse of a fairy realm powerhouse, I don't know what it is for. But what is certain is that at that time, even if the fairy realm powerhouse was dying, he still held it tightly in his hand. The beautiful maid did not hide the origin of this piece of black iron.

"What does this mean? Maybe he was holding this piece of black iron just before he died?" Xiao Pan glanced at his mouth, obviously such a reason could not prove that this piece of black iron was extraordinary.

Duan Ling's cultivation was running, and his spiritual sense carefully probed this piece of black iron, but he didn't see any clues from it.

"There is another reason, because at that time it was said that there was a Tongxian vine by his side, which was next to him, but until he died, he didn't touch the Tongxian vine, but just firmly held this piece of black iron!"

After the beautiful maid finished speaking, Duan Ling's expression suddenly froze, if it was really placed together with a Tongxian vine, then the origin of this piece of black iron was really debatable. After all, the immortal vine is too precious, and it is the last ray of hope for all monks who cannot enter the immortal realm from the Tianhe realm. Tongxian vine is extremely rare and is a valuable treasure.

"Doesn't he have two hands, what is his other hand doing, why doesn't he use his other hand to grab the immortal vine?" Xiao Pan asked with a smile.

He was in the middle of a petrified swamp, and with his other hand he was clutching a vine, and many of his predecessors had told him that he could have left if he hadn't grabbed the piece of black iron. It was precisely in order to grasp this piece of black iron that he finally had no time to leave, and finally died of petrification. ”

Duan Ling originally thought that what Xiao Pan said was quite reasonable, but after listening to the explanation of this beautiful maid at this time, his heart suddenly began to sway again. If what this beautiful maid said was true, then in the situation faced by the fairy realm powerhouse at that time, he should indeed grab the most valuable items. And he didn't grasp the priceless Tong Immortal Vine, but grabbed this piece of black iron, could it be because he had already stepped into the Immortal Realm, and the reason why the Tong Immortal Vine was not attractive to him? Duan Ling felt that it was not!

Although the Tongxian Vine was useless to the immortal who had been petrified and died, if he brought it out, even if he exchanged it for a treasure of extremely high value, it would not be an exaggeration, but why did he not want the Tongxian Vine, but instead wanted this ordinary black iron? The answer is obvious, the probability that the value of this piece of black iron is higher than that of the Tongxian Vine is about eighty percent.

Duan Ling also believed that he was definitely not the only one who had thought of these key issues. But even if you know that the value of this piece of black iron is higher than that of Tongxian Vine, but you can't find out its value, what's the use of buying it?

"Can you take it out and take a look?" Duan Ling asked the beautiful maid on the side.

The beautiful maid nodded, and used a very special technique to fiddle with it for a long time, and then took out the piece of black iron and handed it to Duan Ling.

The black iron fell into Duan Ling's hand, it was about four inches long, and it was covered with rust, he tried to erase those rust marks, but found that the rust was surprisingly hard, he used all his strength, but he couldn't wipe off any rust on it.

"These rusts can't be wiped off, our sect master has invited many fairy realm powerhouses to study this piece of black iron, but they haven't found anything. The beautiful maid couldn't help but smile secretly when she saw that Duan Ling was trying her best to wipe the rust off the black iron.

Duan Ling's face immediately showed embarrassment, his spiritual sense was covered under the black iron in his hand, this time it suddenly made him look stunned for an instant, but he quickly returned to normal, but his heart was beating extremely violently.

"Big brother, show me. Xiao Pan reached out and grabbed the black iron from Duan Ling's hand, muttering to himself that he couldn't see any difference, turning it over and over.

Duan Ling's spiritual sense once again covered the black iron block in Xiao Pan's hand, and as before, it seemed that the black iron block immediately became ordinary again, which made Duan Ling immediately have some guesses in his heart!

"Even if you're a treasure tossing and turning like this, you can't see it. Duan Ling said to him without blushing and without a heartbeat.

"I've checked it with my psychic sense, and it's just an ordinary piece of black iron. Facing Duan Ling's laughter, Xiao Pan said extremely innocently.

"Sure enough, is that really the case?" Duan Ling thought in his heart, and once again took the black iron from Xiao Pan's hand, and his spiritual sense once again covered the black iron.

Three small characters hidden under the rust clearly came into his mind, and at this moment, Ling could be sure that this black iron was absolutely extraordinary, and there was a magical skill engraved on it. Just hearing its name made him feel an aura of domineering. Zhen Xian, Zhen Xian, even if it is a fairyland, it will be ruthlessly suppressed.

Zhenxian Seal!
