Open the wooden box and look inside.

Placed in the center of the box was a palm-sized object that resembled a much thicker arrow.

"What is this?"

Zhang Yun took it out of the wooden box with a puzzled expression, and vaguely understood its function.

At this time, the shopkeeper's explanation came into his ears in a timely manner: "Changhong Shuttle, the air control appliance, was originally made for Jindan to use, but something went wrong on the way to refining, and the formation engraved in the inside of the seal plummeted for some reason, and it could only be dealt with as a defective product." ”

As he spoke, the shopkeeper looked at Zhang Yun with a speechless expression on his face, and said with a wry smile: "Don't you think I'm entertaining you, even if it's a defective product, its materials are also used enough, the outer layer is made of Dinosaurus scales, which is enough to resist the full force of the peak foundation building monk, and the inner layer is a magic circle carved out of the cold chalcedony seal, which can ensure the smooth flow of spiritual power to the greatest extent, not only that, but its speed is also incomparable, even faster than Ling Xianzhou, if it is not a refining failure, how can this kind of treasure be sold to a foundation building monk?" ”

So you sold me this thing that Jindan couldn't look down on and that the foundation building master couldn't afford?

That's too bad, isn't it?

But...... I'm really moved.

It is one percent faster than Ling Xianzhou, and it can also be used as a shield at a critical moment.

I have to say, this thing is really fragrant.

Zhang Yun licked his lips and asked, "What's the price?" ”

"Seven thousand... No. The shopkeeper was halfway through his words, and quickly changed his words: "Five thousand spirit stones!" All you need is five thousand spirit stones, and you can take them! ”

Five thousand, that's not too expensive.

You must know that the cost of an alchemy furnace has already exceeded this price, and it is still worth buying an over-spec sky-catching device.

However, Zhang Yun still has a concern in his heart.

He thought about it, took out five thousand spirit stones from the storage bag, and traded directly to the other party: "I want something, but you have to tell me clearly, where its flaws are." ”

The things that Jin Dan can use, even if the power has been reduced, are not something that the weak people in the foundation building period can control.

There must be a fatal flaw in this thing, otherwise the other party would not have sold it to itself at such a cheap price.

Zhang Yun thought very clearly, if he wanted this thing, he must find out where the hidden danger is, he doesn't want to be killed by what he bought with a lot of money.

The shopkeeper saw that he was straightforward, and he didn't go around the bend with him, and directly explained the key points: "Controlling Changhong Shuo is extremely consuming of divine sense, and the divine consciousness in the early stage of foundation building must be stopped after a quarter of an hour at most, otherwise there will be a risk of depletion of divine consciousness."

In addition, the shackles of spiritual power are also a big problem, with your current cultivation, even if you are desperately exhausted by your divine sense, you can't control it for more than two quarters of an hour in a row.

The depletion of the divine consciousness can still be regained, but if there is turmoil in the true element, it will be a matter of death.

If it is not a last resort, it is not recommended that Taoist friends control this thing for a long time. ”

Well, I knew it wasn't that simple.

Zhang Yun was both fortunate and a little regretful.

Divine consciousness is not a problem for him, with the breakthrough to the foundation building period, his divine consciousness is comparable to the late stage of foundation building, and there will be no depletion of divine consciousness as the shopkeeper said.

But the limitations of spiritual power cannot be bypassed.

You can only control two quarters of an hour at most, what's the use of this?

There is definitely no need to think about the long journey, and it can only be used to escape at a critical moment......

And when you think about it, you don't seem to feel lost.

Just because you can't use it now doesn't mean you won't be able to use it in the future.

When his cultivation goes up, in the middle and late stages of foundation building, won't he be able to travel for a long time?

At that time, there is no need to count the day of Ling Xianzhou's departure, and it is good to be able to choose the time more flexibly and fly to your destination.

Thinking of this, Zhang Yun felt that this transaction was not a loss, at least it could save its life at a critical moment, and this alone would make a profit.

Maybe someone else's life may only be worth about five thousand spirit stones, but his life is different, much more expensive than others.

Five thousand spirit stones in exchange for so many benefits, it's simply not too profitable.

Changhong Shuo carefully received the storage bag, Zhang Yun nodded with satisfaction, and then asked about other items.

"As for magic weapons, this one is enough, I don't know if you have some things out of the way, such as poisons or poison formulas or the like."

"Poison?" The shopkeeper was stunned for a moment and asked, "I don't know what kind of poison you need?" In general...... It's not easy to use this kind of thing, and it's easy to hurt yourself. ”

Easy to hurt yourself?

For others, this concern may be raised, but he does not need to care about the possibility of accidental injury.

Don't forget that he is an ice spirit root, and can control both water and ice at the same time.

Although his control over water is a little weaker, it is still easy to wrap poison in ice.

The poison is stored in the ice crystals, first, it will not volatilize, and secondly, there is no possibility that the ice ridge will accidentally hurt himself, and at the same time, the poison wrapped in the ice crystal is also very hidden, and it can catch the opponent off guard.

If it weren't for that, he wouldn't have to refine the poison, mainly because the poison was too similar to him, so strong that it was almost tailor-made for him.

"I want a poison that can be dissolved in water, preferably with a more direct effect." Zhang Yun first put forward two basic requirements, and then continued: "By the way, I heard that the two poisons of heart devouring and soul leaving are very strong, I wonder if you have any here?" ”

"Daoyou is talking about the special formula of Sanssouci Pavilion, I don't have that thing here, but ......" The shopkeeper pinched his chin and muttered for a long time, and said: "The poison of our Holy Sect is estimated to not be sold to you, but I have a copy of the "Poison Sect Secret Book" here, which is a secret book of alchemy left after the Poison Sect destroyed two hundred years ago, I don't know if you want it." ”

Two hundred years, a bit of time.

And the sect has been destroyed, I'm afraid that the medicinal properties are not very good.

But with my current cultivation, it seems that I don't need to think about this problem, right?

How can he destroy the door also be the power of Jindan, the poison of the Poison Sect can't work on Jindan, what does it have to do with him building a foundation?

Thinking about the connection clearly, Zhang Yun said without thinking about it: "Tell me how much it is, I will definitely want the right price." ”

"Two thousand spirit stones, no two prices."

Maybe he didn't have much confidence when he sold Changhong Shuttle, which made the shopkeeper feel breathless, but he was full of confidence when he opened his mouth this time.

Zhang Yun didn't ink with him, and said cleanly: "Okay!" Then two thousand spirit stones, I want this thing! ”
