"That's right, it's a recipe, and it's something you can learn directly." In the cognition of NPCs, there is also a distinction between formulas, one is handwritten, and this formula is just a simple formula, just like the previous instructions and recipes.

The value of this recipe is not high, after all, there are only materials, and some of the better ones will have a production process, but they still need to be explored, which is a great waste of time.

But what Su Yu said about the formula that can be learned directly is different, after learning, it is equivalent to self-learning, just like directly entering the production method in the head of the person who is learning, and when the time comes, as long as there are materials, you can make it directly, and there is almost no possibility of failure.

"Shall we go in and talk?" Since he can buy the formula, Tang Lu naturally will not let go of this opportunity.

As the deputy captain of a large caravan, Tang Lu can be said to be very familiar with the value of space bags...... You know, this is something that even a high-level magician can't easily make!

The so-called space magic is actually an extremely mana-consuming magic skill, and it is rare for high-level magicians to use it without restraint, let alone apply this magic to an item, so that such an item has the effect of space magic.

Although it is not unheard of a long time ago that someone has made an item similar to a space bag, which can store things regardless of volume, but most of them are just rumors, and before that, no one knew if there was a real space bag.

"Okay." After entering the room, Su Yu took out the recipe directly.

Tang Lu endured her curiosity about the formula and asked Su Yu why she sold the formula.

Originally, it is good to pay the money with one hand and deliver the goods with the other hand, and generally do not ask the reason for the root cause, after all, this is a private matter of the other party.

But this time the formula was a bit special, and if she really wanted to buy it, she would definitely have to pay a great price, so Tang Lu had to be cautious.

"Don't hide it from Captain Tang, in fact, there are not many materials for making this space package, there are only less than five, but one of them is difficult to obtain......" Su Yu did not explain what this material was, but she did not lie, but briefly explained the most real situation of the space package.

"Materials are rare, and there are naturally not many finished products that can be made, as a lord of a small territory, instead of guarding a treasure that cannot be opened, it is better to exchange this treasure for something with practical significance...... Captain Tang, are you right? ”

When Su Yu was talking, Tang Lu had been carefully observing Su Yu's expression, but she didn't see anything wrong.

And the content of what she listened to Su Yu said was also reasonable, and it didn't look like she was lying.

"Lord Su has two recipes?" The reason why Tang Lu asked this was because Su Yu had already taken out the finished product of the space bag.

If there is a finished product, it means that someone has already made it, so Tang Lu asked Su Yu if he had two recipes.

Because she suspected that Su Yu kept a recipe for herself for others to learn, and the other for sale.

If someone else has a recipe for making a Space Pack, it's not as valuable as the one in the world.

"No, there's only one recipe for the Level 1 Space Pack." Su Yu didn't lie, the recipe for this level of space pack was indeed only this one.

She had other recipes, but they were other level space packs...... So it's not a lie, it's just a play on words.

Tang Lu frowned and took out the space bag in his hand.

"So where did the space pack sold by Lord Su come from?"

Faced with Tang Lu's suspicions, Su Yu said without changing his face: "Naturally, it is something that is put together with the formula, and when I saw it, I brought it back together." ”

Lying is bad, but sometimes it is necessary.

Suyu didn't want to expose the fact that someone in the territory would make a space pack, as it would not be safe for Dolly and would also depress the value of the recipe itself.

As for whether Tang Lu believes it or not, that's her business.

"Lord Su, make a price." Tang Lu actually couldn't say whether Su Yu was lying or not, but she felt that Su Yu had a few words that should be true.

For example, this is a recipe that can be learned directly, which means that they can find someone they trust to learn the recipe at that time, or even they can learn the recipe themselves.

That alone makes this recipe worthless.

Secondly, Su Yu said that the ingredients of this recipe are rare, which must also be true.

If it weren't for the rarity of the ingredients, she would definitely choose to keep it for herself, even if there were already people in the territory who could make this thing, she also needed to ensure the uniqueness of the formula, so that no one would come to steal the business.

"The transaction price of the space package just now is three hundred and seventy gold coins, so the price of this formula will be set at ten times, of course, I also know that I can't get so much money for a while, so Captain Tang can set it first."

Ten times three hundred and seventy, that's three thousand seven hundred gold coins, which is not a small amount!

You must know that all the liquidity of many small families may not be able to have more than 3,000 gold coins in total, even if Tang Lu is the vice captain of a large caravan, she will definitely not have the right to be able to take out so many gold coins at one time.

And she doesn't have so many gold coins on her.

You must know that before buying the space pack, the current liquidity of this caravan is only a little over a thousand, because after buying the space pack, the funds were instantly reduced by one-third, and only more than six hundred remained.

Tang Lu calculated the price, and after thinking about it, he said: "Three thousand seven hundred is not good, it is too expensive, my highest authority in the caravan is only two thousand five hundred gold coins." ”

The authority here refers to the amount that Tang Lu can withdraw directly from the caravan's account after returning to the caravan base camp without the approval of other deputy captains and captains.

Different people can withdraw different amounts, Tang Lu because of her ability, the amount she can withdraw is already the highest except for the captain himself, but even so, there is still a full half gap from Su Yu's offer!

"There's no urgency in this matter, Captain Tang can discuss it with others." Su Yu is really not in a hurry, anyway, he has just received three hundred and seventy gold coins, plus the dozens of gold coins that Bu Guo sold in the trading area, as well as the stall fees of those who set up stalls in the trading area and the income in today's territory, Su Yu now has close to five hundred gold coins in hand.

The money was enough for her to buy a lot of things in the caravan.

"If the transaction is pleasant, I can inform Captain Tang of the way to obtain the rarest ingredient in the formula."
