The next day, Ding Yi went out early and bought a lot of metal materials that were not of high grade but extremely hard.

Then, he locked himself in the remodeled West Chamber's refining room, took out the third-order high-grade small refining furnace that had been in the storage bracelet for several days, and placed it in the middle of the room.

Then he turned on the defense and soundproofing prohibition of the room, took out the large pile of materials he had bought before, and made it seriously.

Taking a deep breath, Ding Yi sat down cross-legged directly opposite the refining furnace, eliminated all distractions, and began to think about what he wanted to restore in this world, as well as the parts of the refining knowledge that could be related to it.

It took a stick of incense to sort out all the information.

Next, ask the system for the price.

[To perfect your idea, you need to create 5263 points!] 】

So expensive!

Hearing the answer given by the system, Ding Yi was shocked.

What is the concept of 5263 points?

You must know that when Ding Yi was the richest before, he only had 177 creation points!

What he wants to refine this time is just a second-order lower-grade magic weapon or below, or it's a little bigger, but it doesn't need so much creation value, right?

Are you going to rob it?

Wait a minute!

Ding Yi suddenly realized something, so he asked again in his heart: What grade of magic weapon does it take to perfect and succeed with 5263 creation points?

[Judging from the host's conception, you need at least a third-order lower-grade magic weapon to barely meet your requirements. Below this level, it cannot be refined. 】

Sure enough, it was my own thinking that went wrong, and I thought things too simply!

Ding Yi recalled several things that had been developed before, either with a simple structure and relatively easy to restore, or improved on the basis of the original, or through a simple rune structure to activate the properties of a certain material itself.

The theoretical knowledge involved in it is not complicated to say.

But what he wants to study this time is different, and it is not an exaggeration to say that it is the cornerstone of the modern industrial system, which contains many of the best of the earth's industrial technology.

If you want to restore it, it is obviously not as simple as replacing the industrial theory with a simple refining theory.

It has to be a perfect combination of the two.

However, what he wants to restore this time is not as commonplace as a watering can, even before Ding Yi crossed, he had only seen it a few times in short videos, such as restoring Damascus Gang's refining method Shenma......

In the face of this kind of aerial pavilion that knows what it is and why it is so, even if there is a system, I don't know where to go.

Perhaps, it's a good idea to start with something smaller?

System! How much manufacturing value is needed to restore a hydraulic jack?

[To perfect your idea, you need to create 23 points!] 】

To restore a small jack, it actually takes a full 23 points of creation value!

You know, when he developed the "HRE Heavenly Expedition" before, he only consumed 15 points of Creation Value!

Is it because he only knows the basic principle of the hydraulic jack, but he does not know its internal structure?

That's not right!

What I'm going to make the system add is the missing part of it, hasn't it all been done before? I've never seen so much Creation Value!

Or is there something critical missing?

Something Critical......

That's right!

It's hydraulic fluid!

On the earth, this thing is indeed an industrial product, but in the world of cultivating immortals, more than ninety percent of the liquid spiritual materials, regardless of whether they can be eaten or not, are classified into the category of alchemy.

For example, Duobaoge made it some time ago, the potpourri with an effect similar to perfume.

Thinking of this, Ding Yi immediately took out a book that recorded the basic materials of alchemy from the storage bag that Feng Shiyu gave him when he was leaving, and read it seriously.

Don't say anything, thank you Feng Qishi for having a rich collection of books!

……

An hour later......

[To perfect your idea, you need to create 15 points!] 】

Half an hour later......

[To perfect your idea, you need to create 9 points!] 】

Another hour later......

[To perfect your idea, you need to create 5 points!] 】

It's done!

This time, the development cost was finally successfully controlled within 7 points!

Nothing to say, give me perfection!

Boom! ——

Boom! ——

Boom! ——

Picking up the hammer of creation and working hard for half an hour, Ding Yi finally used the existing materials in his hand to restore a hydraulic jack.

However, the system did not give him any reward.

Because, there is no hydraulic oil......

The production of hydraulic oil is still in the category of alchemy in the immortal cultivation world, and Ding Yi, a second-order low-grade refiner, does not have the conditions to refine it.

Sure enough, the industrialized gods are not something that one person can play with at all!

Ding Yi decisively went out again, found Miss Lian Rou who was often in contact with him in Duobao Pavilion, and directly slapped a recipe in front of the other party: "Miss Lian Rou, I want to ask the alchemist of your pavilion to help me refine a special oil, here is the refining formula." ”

Lian Rou took the formula, frowned and looked at it for a moment, then got up and said with a smile: "It's the first time I've encountered such a strange request, if it weren't for the invitation of the Ding Artifact Master, I would definitely refuse in person without hesitation." ”

Ding Yi knew that what the other party said was true, so he immediately got up and said to the other party: "In this way, thank you Miss Lianrou." ”

"Don't be too busy saying thank you, I'll help you ask."

……

After a while, Lian Rou took the formula with an apologetic face and turned back: "I'm sorry, Ding Artifact Master, all the refiners above the second order in the Despise Pavilion are unwilling to refine this strange formula of unknown origin and unknown purpose, they said that they are afraid of soiling their alchemy furnace, and I am not too reluctant." ”

Alchemists one by one, are they all so arrogant?

Ding Yi complained in his heart, and then continued to ask, "What about the first-order ones?" ”

Lian Rou shook her head again: "Duobao Pavilion only recruits third-order alchemists, as well as the best of the second-order alchemists, first-order alchemists, and they are not qualified to serve for Duobao Pavilion yet. ”

Well, you Duobao Pavilion is even more arrogant!

Leaving the Duobao Pavilion with the formula, Ding Yi turned back to the street in front of Qingyufang, which he was most familiar with. On the way, it was found that there was a seal on the gate of Qingyufang, and there were also two notices next to it, "Idle people, etc., must not approach" and two notices for Xin Chao to be wanted by the reward.

Ding Yi didn't pay attention to it, but found an alchemy workshop called "Danxiang Pavilion" not far from Qingyufang.

Ding Yi's predecessor, when he needed to work overtime, he came here to buy Qi Replenishing Pill a few times, and he was familiar with it.

However, it seems that this kind of shop that has only done a few small transactions, no matter how familiar it is, it is impossible to be more familiar than Duobaoge. His order, even a big acquaintance like Duobaoge is reluctant to accept it, like Danxiang Pavilion can barely be regarded as knowing each other, and naturally it is no exception.

While saying something, "Danxiang Pavilion is a serious alchemy workshop, and I have enough respect for the refiners, and I will never refine this kind of formula of unknown origin and unknown use, please go to another house to have a look."

politely pushed Ding Yi outside.

However, a small business is a small business, and their waist pole cannot be as hard as Duobaoge.

When Ding Yi directly took out 100 lower-grade spirit stones and said that he wanted to order 10,000 catties, the boss of Danxiang Pavilion immediately said: "Ding Ware Master, you see people really accurately!"

From today onwards, we at Danxiang Pavilion will not do anything, and will refine this special oil specifically for the Ding Ware Master.

Until 10,000 catties are refined! ”
