Yang Yifei happily sat on the chair, looked at the dazzling array of various potions on the shelves, smiled and said loudly to Lei Shande: "Mr. Lei Shande, I am here to buy potions, healing potions and magic potions, I want as much as you want." ”

Lei Shande said in surprise: "Isn't His Majesty the King himself an alchemist?" I heard that you also learned to refine potions from Akara, why did you ask me to buy them? ”

Yang Yifei explained: "I know how to refine medicines, but I don't have time!" ”

Lei Shande suddenly said: "No problem, my stock is very sufficient, even if it is all given to His Majesty for free, but I have one condition." ”

Yang Yifei said: "Sir, if you have any conditions, you can just mention it." ”

Lei Shande said: "I want to know how the weapon called the grenade is refined, and I am willing to use the free refining potion for His Majesty in exchange for the recipe of the grenade." ”

Yang Yifei couldn't help but laugh and said, "Mr. Lei Shande, the grenade is not a potion, but an alchemy product, which involves the fusion of alchemy and mechanism, which is very complicated. ”

"The refining method is in my head, but with the knowledge you have, you can't refine the grenade, but I will open a vocational school in the future, and I will pass on the relevant knowledge when the time comes."

"If Mr. Reisander is interested, he can go to the school to study at that time."

Lei Shande listened to Yang Yifei's explanation, and he had nothing to say, although he was a proud senior pharmacist, he also understood that there was a specialization in the art industry.

He dared to say that Lu Gain did not have a better pharmacist than him, but he was not proficient in alchemy, and his eyes were even more black.

The conditions were not negotiated, and the purchase of the potion was naturally purchased at the original price, and Yang Yifei did not really buy up Lei Shande's inventory, and bought 1,200 bottles of healing potions and magic potions each.

However, according to Lei Shande's request, Yang Yifei paid the bill with gems.

Between alchemists and apothecaries, gems and crystals are hard currency, and gold is of little use to them, as long as they are enough to survive.

"Master, why are you buying so many potions? None of the potions that Lord Akara gave us back then had ever used! In the car, Flavi couldn't help but ask curiously.

Yang Yifei smiled mysteriously and said, "You'll know in a while." ”

Back in the palace dormitory, Yang Yifei closed the door, and only Flavi and Kasha were present.

I saw Yang Yifei flip over his hand and take out the Hradic cube and put it on the table.

The Heradic cube is actually a boxy box with a side length of more than ten centimeters, engraved with simple and mysterious runes on the surface, and it is a space of its own, with a volume of two cubes, which can also be used as storage equipment in ordinary times.

Kasha and Flavi sat on Yang Yifei's wide desk on the left and right, watching Yang Yifei's movements, and the beautiful legs that were shaking in front of him couldn't distract him.

Yang Yifei took out a bunch of healing potions and magic potions, put three bottles of each into the block, then put in a complete gem, and finally stretched out his palm and pressed it on the surface of the block, outputting mana, and activating the synthesis function of the block.

The runes on the block were quickly lit up, spreading extremely quickly, and soon enveloping the entire block.

"Buzz"

The cube shook slightly, the light disappeared, and Yang Yifei happily took out the items in the cube.

Kasha and Flavi looked closely, and saw that it was a bottle of purple liquid, round and the size of a fist.

Seeing Yang Yifei playing with the big purple bottle with his hand, Flavi asked curiously, "Master, what is this?" ”

Yang Yifei said with some excitement: "This is called the comprehensive rejuvenation potion, it is a real miracle medicine, as long as the person is not completely dead, even if there is only one breath left, it can save the person back." ”

"After drinking this bottle of potion, no matter how seriously injured you are, you can heal in a very short time, and the mana is full, this bottle of potion is a life!"

Kashya was surprised: "So powerful? ”

Yang Yifei said: "It's so powerful, but the cost is too high, a bottle of comprehensive rejuvenation elixir, it takes three bottles of healing potions, three bottles of magic potions, and a complete gem to synthesize." ”

"The attributes of the gem don't matter, you can have any attributes, but it must be complete, the cracked ones can't be synthesized, and the broken synthetic potions only have this one-third effect, don't draw ...... Uh......"

Speaking of this, Yang Yifei was suddenly stunned, and after a few seconds of pause, he slapped himself violently.

It's just a groove, and he suddenly feels a little sorry for the math teacher.

"What are you doing? Why do you smoke yourself? Kasha rubbed Yang Yifei's cheeks, which were flushed by himself, in distress.

Yang Yifei smiled bitterly, and then in front of the two women, he used three shattered gems plus nine bottles of healing potions and magic potions to synthesize three vials of rejuvenation elixir, and then synthesized three bottles of rejuvenation elixir into a bottle of comprehensive rejuvenation elixir.

After doing all this, Yang Yifei used nine broken gems to synthesize three split gems, and then used three split gems to synthesize a complete gem.

In the same kind of items, to synthesize higher-level items of the same type, the ratio is 3 to 1, that is, three parts are combined into one copy.

Flavi, Kasya: "......"

After reading what Yang Yifei did, the two women were speechless, so three shattered gems and eighteen bottles of potions could be combined into a bottle of comprehensive rejuvenation elixir.

However, it takes nine Shattered Gems to synthesize a complete gem, and directly using the Broken Gem to synthesize a comprehensive rejuvenation potion is equivalent to saving 12 bottles of Elixir, but it costs 6 more Shattered Gems.

That's really ...... The recipe for the loser!

The potion is made from herbs that can be cultivated on a large area, plus a little gem essence, how much is it worth? How much do gemstones cost? This elementary school student can calculate the account!

In the afternoon, Yang Yifei didn't do anything, just synthesized the elixir there.

After exhausting all the potions, he added a few more bottles, and finally got 134 bottles of fully rejuvenating potions, which only cost 400 Shattered Gems.

If you use whole gems to synthesize, you can get 400 bottles of full rejuvenation potion, but you have to consume 400 whole gems, which is equal to 3600 shattered gems, which is too bad.

You must know that the extra 3,200 Shattered Gems are enough to refine nearly 20,000 bottles of Elixir, and more than 2,000 vials of comprehensive rejuvenation Elixir can be synthesized.

Lu Gain is not only a pharmacist in Reshande, but also a Dragognam!

He is also an alchemist and specializes in crafting sorcerers' staffs and necromancers' canes and, of course, scrolls.

But he is also a part-time pharmacist, although the inventory is not as much as Lei Shande, who specializes in medicine to eat, but there are also a lot, Yang Yifei bought 600 bottles of two kinds of medicine from him.

In the end, Yang Yifei's total stock of fully rejuvenating elixir was 200 bottles.

At dinnertime, Yang Yifei held a banquet in the palace, which was attended by all the officials at or above the battalion commander level in the army, and the ministers of the DPRK and China also brought their families to attend.

There were also some big businessmen who were very famous in Lu Gain, and they also received invitations, and there were nearly 200 people attending the banquet at the end.

The old rules, two sets of Manchu and Han full banquets were laid out, and even those rich merchants and tycoons who were used to eating all kinds of delicacies were conquered by this palace banquet, and they didn't know any of the foods, but they almost swallowed their tongues.

Through this palace banquet, people of insight learned about the background of their majesty, although this is only the tip of the iceberg.

The cooks in the palace were full of bewilderment, they had not received any news that His Majesty was going to hold a banquet, so where did those delicacies come from?
