"Oh, what material?!" Yu Changjun asked suspiciously, you must know that Wang Xin has a warrant given by Yu Changjun, since it can't be taken out of Wang Xin's hands, it must be beyond Wang Xin's access authority, Yu Changjun naturally cares!

"The other things are easy to say, but the formation materials of the four grades are a little insufficient, please help!" Li Shi said.

"Four-grade formation materials?!" Yu Changjun was stunned for a moment, and said in surprise, "This array device costs such a high-quality material?!"

At the beginning, Li Shi didn't feel anything at all when he was researching and making the array card series, after all, Li Shi at the beginning was directly scraped from the Master Qingze, and the most was the formation materials of the three and four grades, which were naturally used at will!

But with the passage of time, there are fewer and fewer of the four-grade materials that he has obtained, and he occasionally uses them to make up a set of samples, Li Shi can naturally pull it out, but if he wants the formation materials of those medical monks to come out by himself, Li Shi is not such a great sage who has scattered thousands of gold!

Therefore, this time a large number of array cards are needed, and Li Shi naturally needs the support of the sect.

It is worth mentioning that the array cards made by Li Shi have always used the materials of the four products as the basis for production, but the array cards made of the four materials can only run rampant in the hands of the monks in the foundation building period, which can be regarded as quite a waste of materials!

Now, Li Shi wanted to make a medical array card, and as soon as he opened his mouth, he reported the four-grade formation materials, even though Wang Xin obeyed Yu Changjun's request and met Li Shi's requirements as much as possible, but it was impossible to meet all the requirements.

You must know that for the monks of the Qinglian Domain, the materials of the four-grade formation may not be used even in the arrangement of the three-grade formation, and as a result, Li Shi wants to make a formation weapon, so he wants to use the four-grade formation materials as raw materials, how could Wang Xin agree.

"Four-Rank Formation Materials...... We don't have many of these materials on the front line, which ones do you want!" Yu Changjun looked at Li Shi, and almost couldn't help but want to press his temples, maybe agreeing to Li Shi's departure just now was the right choice!

But I just refused to let others leave, and now that others are doing their best for the field hospital, I can still stop it!

Let's be realistic, dig out the spirit stone!

"Mainly Shaoyang Wood, Ning Yuan Grass, Purple Ink Vine ......" Hearing Yu Changjun's words, Li Shi was not polite, only heard a lot of materials in Li Shi's mouth and reported it, which was really not polite at all!

"Okay, okay! I'll give Wang Xin another share of the four grade spirit stones worth 200,000 and four grades, and let him get it for you!" At this time, Yu Changjun looked at Li Shi fiercely and said, "At that time, I will see at least fifty sets of array cards!"

"Fifty sets?!This is too much!" Li Shi seemed to be like a cat that had only been stepped on by its tail, and the whole person bounced up, and said unwillingly, "Ten sets, ten sets, all of this kind of things have to be made from scratch, and the success rate is very low!"

"Fifty sets! This is the task!" Yu Changjun said without hesitation, "I don't care what method you use, in short, you make all the real cards of these fifty sets, and I will personally check them when the time comes!"

"Don't, I don't have ten sets, fifteen sets, how about fifteen sets!" Li Shi was still struggling at the moment.

"Take him down and let Wang Xin come to see me!" Yu Changjun did not hesitate to give Li Shi an eviction order at this moment!

Li Shi unwillingly came out of Yu Changjun's camp, but the original grief and anger on his face had already disappeared!

At this moment, Li Shiyan seemed to only have the appearance of a spirit stone in front of him, and the share of 100,000 four-grade spirit stones, fifty sets of medical array cards was naturally more than enough.

In the past half a month, Li Shi, the director of the front-line field medical department, has lived quite comfortably, with the establishment of rules and the operation of the institution in accordance with the rules and regulations, Li Shi has become a big idler in the field hospital, especially even if Li Shi wants to come forward to help these injured monks for treatment, Li Shi is a rather disgusting choice for those injured monks.

When Li Shi really wanted to treat these injuries, his hands accidentally shook a few times!

Of course, this is also understandable, after all, any normal person who chooses to be treated by a beautiful fairy with fluttering clothes, or choose to be treated by a mediocre-looking male monk, then any guy will make the same choice!

In particular, the smile of the beautiful fairy can be used as an anesthetic, but if Li Shi presides over the treatment, it will be completely in a double hell for the monk who is being treated, which makes the injury aggravated, but it is not possible.

Therefore, Li Shi, as the director of the field hospital, soon became a redundant person in the field hospital he created. If it sounds good, it is naturally Dinghaishen Needle, and if it is ugly, it is naturally boring.

And Li Shi really wanted to go back when he went to find Yu Changjun, but if Yu Changjun let him stay, Li Shi did not hesitate to come up with his own alternative plan and maximize the benefits of this matter.

Fifty sets of medical array cards were quickly produced, and after Yu Changjun's inspection, these things were sent to the hands of those medical monks.

If Li Shi is as honest as water, and these medical formation materials have just been spent, Yu Changjun will definitely not believe this kind of thing.

As a third-grade monk, he looked at the array cards in Li Shi's hand and was able to roughly estimate the materials that Li Shi needed to make these array cards, according to Yu Changjun, Li Shi could save about four or five thousand four-grade spirit stones at most about four or five thousand formation materials, in Yu Changjun's opinion, these materials should be regarded as a reward for Li Shi to establish a field hospital.

It's just that what he didn't expect was that in his estimation, the success rate of Li Shi's production of array cards should be about 60%, this estimate is reasonable, after all, Li Shi's medical array cards have just begun, and if the proficiency of these things in the design of these formations, material running-in, and formation construction is not enough, it will affect the finished effect of the formation made by the array, which can reach more than 60% This is already a genius who sees Li Shi almost once in a thousand years, and Yu Changjun has overestimated Li Shi as much as possible.

But he still underestimated Li Shi's level, because with the help of Yi Shu Array, the success rate at the beginning was indeed less than 50%, but the more Li Shi made it later, the smoother it became, and after more than ten points, the success rate of Li Shi's production of this set of medical array cards has exceeded 90%, and it is constantly approaching 95%.
