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

Leishande said in surprise: "Isn't Your Majesty the King also an alchemist? I heard that you have learned to refine potions from Akara, so why did you buy them from me?"

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

Lei Shande suddenly realized and said, "No problem, I have very sufficient stock. Even if I give it to His Majesty for free, I have one condition."

Yang Yifei said: "Sir, you can just raise any conditions."

Lei Shande said: "I want to know how the weapon called grenade was refined. I am willing to use free refining potions for Your Majesty to exchange the formula for grenades."

Yang Yifei said with a lot of laughter and cry: "Mr. Leishande, grenade is not a potion, but an alchemy product. It involves the fusion of alchemy and mechanism techniques, which is very complicated."

"The refining method is in my mind, but with the knowledge you have, you cannot refine grenades. However, I will open a vocational school in the future and will impart relevant knowledge at that time."

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

After hearing Yang Yifei's explanation, Lei Shande had nothing to say. Although he was a proud senior pharmacist, he also knew that he had specialized in his profession.

He dared to say that Lu Gaoyin had no better pharmacist than him, but he was not proficient in alchemy, and his mechanical skills were even more ill-watched.

The conditions were not agreed upon, so the purchase of the potion was naturally the original price. Yang Yifei did not really buy all Leishande's inventory, and healing potion and magic potion each bought 1,200 bottles.

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

Between alchemists and pharmacists, gems and magic crystals are hard currency, and gold coins are useless to them, just enough to maintain their lives.

"Master, why are you buying so many potions? Lord Akara has never used the potions he gave us!" Flavi couldn't help asking curiously in the car.

Yang Yifei smiled mysteriously and said, "You will know in a while."

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

Yang Yifei took out the Heradik square and placed it on the table.

The Heradik square is actually a box with a side length of more than ten centimeters, with a square box engraved with ancient and mysterious runes on the surface, and a space inside it has two cubic volumes. It can also be used as storage equipment in normal times.

Kasha and Flavi sat on Yang Yifei's wide desk on the left and right. Looking at Yang Yifei's movements, the beautiful legs that were shaking in front of him could not distract him.

Yang Yifei took out a bunch of healing potions and magic potions, put three bottles into the square, then put a complete gem, and finally extended his palm to press it on the surface of the square to output mana, activate the synthesis function of the square.

The runes on the block were quickly lit up, spreading very quickly, and soon enveloped the entire block.

"Buzz"

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

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

Seeing Yang Yifei playing with the big purple bottle in love, Flavi asked curiously: "Master, what is this?"

Yang Yifei said excitedly: "This is called the full recovery potion, which is a real magical medicine. As long as the person is not dead yet, he can save the person even if he only breaths left."

"After drinking this bottle of potion, no matter how serious the injury is, it can be cured in a very short time. Moreover, the magic power is full. This bottle of potion is a life!"

Kasha said in surprise: "So awesome?"

Yang Yifei nodded and said, "It's just that it's so powerful, but the cost is too high. A bottle of full-scale recovery potion requires three bottles of healing potion, three bottles of magic potion, plus a complete gem to synthesize it."

"The properties of gems are irrelevant. Any attribute is OK, but it must be complete. The cracked one cannot be synthesized. The synthesis of the broken ones is only one-third of the effect, so it is not...uh..."

Speaking of this, Yang Yifei was suddenly stunned. After a few seconds, he slapped himself.

He was so sad that he felt a little sorry for the math teacher.

"What are you doing? Why are you doing so?" Kaxia rubbed Yang Yifei's cheeks that were slapped red by himself with heartache.

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

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

Among similar items, the ratio of higher-level items of the same type is 3 to 1, that is, three parts are synthesized into one.

Flavi, Kasha: "…"

After reading what Yang Yifei did, the two women were speechless, so three broken gems and eighteen bottles of potions could be synthesized into a bottle of full-scale rejuvenation potion.

It takes nine pieces of broken gems to synthesize a complete gem. Using the complete gems directly to synthesize a full recovery potion, which is equivalent to saving 12 bottles of potion, but spending 6 more broken gems.

This is really... a prodigal synthesis method!

The potion is made of herbs that can be grown on a large scale, plus a little gem essence. How much is this worth? How much is the gem? This elementary school student can calculate the calculations!

In the afternoon, Yang Yifei did nothing and just synthesized the potion.

I used up all the potions and added a few bottles myself. Finally, I got 134 bottles of full-scale rejuvenation potion, and only 400 fragmented gems were spent.

If you synthesize it with a complete gem, you can certainly get 400 bottles of full recovery vitality potion, but you have to consume 400 complete gems, which is equivalent to 3,600 broken gems, which is a loss.

You know, the 3,200 extra shattered gems are enough to refine nearly 20,000 bottles of potions, and can synthesize more than 2,000 bottles of full-scale potion recovery.

Lu Gaoyin is not the only pharmacist, Raysander, and Zhuo Gnan!

He is also an alchemist, specializing in making magicians' staff and necromancers' staff, and of course, scrolls.

But he also worked as a part-time pharmacist. Although the inventory is not as high as Lei Shande, who specializes in reliance on medicines, there are also many. Yang Yifei bought 600 bottles of two kinds of medicines from him.

Finally, Yang Yifei's total stock of full recovery potion was 200 bottles.

At dinner, Yang Yifei held a banquet in the palace, and all the battalion commanders and above in the army attended, and the ministers in the court also took their families to attend.

There are also some famous businessmen of Lu Gaoyin who have received invitations, and nearly 200 people attended the banquet in the end.

The old rules were that two sets of Manchu and Han ches were put out, and even the wealthy businessmen who were used to eating various delicacies were conquered by this palace banquet. They didn't recognize the food, but they almost swallowed their tongues.

Through this palace banquet, the knowledgeable people learned about the background of His Majesty, his king, although this was just the tip of the iceberg.
