While taking a nap outside the door, Div was suddenly awakened.

  He jumped up suddenly, his eyes focused on the colorful potion in Jia Lan's hand, and asked curiously: "What is this?"

  Hearing the noise, Casey and the old mercenaries also rushed over from their resting place, and looked at Jia Lan curiously.

  Jia Lan looked at the old 'thief' who had lost an arm, and then fixed his eyes on the muscular Div, and said with a smile: "Come, try my new invention."

  As he said, he handed Div a crystal test tube filled with transparent liquid.

  Div curiously pulled out the stopper, sniffed it, and drank it all. After drinking it, he smacked his lips and said: "It doesn't taste much."

  However, he didn't notice that Lemley beside him suddenly trembled all over and hid under the table.

  The old mercenaries were all shocked. Does this guy know what he just drank?

  That's a potion made by a magician!

  Who told you to try it casually?

  Jia Lan looked around, picked up a bucket of dirty water for cleaning, sprinkled it in the yard, pointed at the water on the ground and said, "Go over and try it."

  Dave was confused and walked over the water according to Jia Lan's instructions, but nothing happened.

  However, Old Jimmy's eyes lit up, and he quickly rushed to Dave's side and touched the ground.

  Everyone realized that there were no footprints left where Dave walked!

  Old Jimmy shouted in surprise: "This... this is...?"

  "Primary invisible trace potion." Jia Lan nodded, "Try this again!"

  As he said that, he handed Dave another light blue potion. Dave drank it without hesitation.

  Jia Lan asked: "How high can you jump with all your strength?"

  Dave scratched his head and said uncertainly: "About two or three meters?"

  "Jump and see! Try your best!" Jia Lan said with a smile.

  Without thinking too much, Div squatted down and suddenly jumped up.

  The result was completely different from what everyone expected. Div jumped into the air like a big flea.

  Although the exact height could not be determined, it was definitely higher than the three-meter-high wall!

  "Eight meters, the effect of the primary jumping potion is limited to this." Jia Lan said with a little regret.

  Div, who did not expect that he could jump so high, screamed, danced in the air, and finally fell heavily to the ground, raising a cloud of dust.

  "Try this bottle again..." Jia Lan stuffed a bottle of milky white, slightly turbid potion to the groaning Di Fu.

  But this time, Di Fu dared not drink it no matter what.

  Old Jimmy quickly snatched it: "Let me try."

  Without waiting for Di Fu to speak, he pulled out the cork and drank it all.

  Soon, Old Jimmy's figure became blurred.

  Stolen story; please report.

  Everyone knew he was standing there, but if you didn't look closely, it would be difficult to find him, as if Old Jimmy was integrated with the surrounding environment.

  "Primary invisibility potion, can only last for one minute." Jia Lan said, put the remaining potion into a leather bag and handed it over.

  "Light body, night vision, shrinking, flying, spider crawling... These are all primary alchemy potions, some of which are weakened versions and can only last for less than a minute."

  "With these, plus your thief skills, it will be more certain to sneak into the Pharmacist Guild and find the Brown family." Jia Lan nodded with a little satisfaction.

  The hidden scar effect on his body gradually disappeared, and Old Jimmy excitedly took the leather bag.

  Although he only had one arm, he tied the leather bag around his waist deftly.

  "There are only six bottles of each potion. I suggest you use one bottle of each to try the effect first." Jia Lan looked at the sky and said with a smile, "I hope you can bring back good news."

  Old Jimmy was as excited as a child, jumping around in the yard to test the effect of the potion, but he didn't make any sound, and he was as flexible as a cat.

  However, Dave and Casey, who were responsible for purchasing medicinal materials, showed strange colors on their faces.

  The eight potions that Jia Lan took out, not counting the labor cost and the difficulty of making, the material cost alone is about twenty gold talans per bottle.

  In other words, the material cost of the forty-eight potions that Jia Lan took out is nearly a thousand gold talans!

  And if these potions are put on the market for sale, the lowest price will not be less than fifteen thousand gold talans!

  Fifteen times the profit, is it high? Not high!

  Among the alchemical potions on the market, although there are several with similar effects to these potions, nearly half of them are unheard of.

  For example, night vision, shrinking, light body... The effect of the earth-based invisible trace potion is similar to the invisibility potion, but it can only wipe away footprints on the mud. It cannot leave footprints on anything like the invisibility potion.

  The water-based mist potion is quite similar to the hazy potion, and the wind potion, like the jumping and floating potions, uses the power of wind to make people jump higher.

  However, the "human shrinking" effect that can change the size of the human body is rarely heard of.

  The effects of these potions often play an important role at critical moments.

  For example, when thieves try to sneak into the lord's treasure house, if they can use these potions, the benefits will far exceed the cost.

  Unfortunately, these alchemical potions are extremely scarce in the market. Every time they appear, they will trigger fierce competition among high-level professionals, resulting in soaring prices.

  However, Jia Lan successfully refined forty-eight bottles in a short period of time, which amazed Casey and others, and they thought that this was simply a rhythm of rolling in money!

  However, refining these potions is not an easy task. It takes a lot of time and requires the magician to concentrate on controlling the amount, combination and temperature of the medicinal materials.

  Finally, it needs to be activated with magic power, and this process requires even more concentration.

  Any mistake in any step will lead to the failure of potion refining.

  Therefore, alchemical potions cannot be mass-produced like ordinary medicines, and only a small amount of stock can be found in the magician's laboratory.

  Except for professional alchemists and magicians who really need these potions, few people are willing to invest so much energy in alchemical potions.

  But Jia Lan only used a few simple spells, just like a magic trick, and completed the work of more than a dozen magicians alone! This is simply a miracle!

  If anyone knew that Jia Lan could make alchemical potions in batches and could make eight different potions at a time, I wonder how many people would be excited.

  Although Casey and Dave lived in the magic city of Coran and had some understanding of magic, they found it difficult to understand the "magic" that Jia Lan used to make those alchemical tools operate on their own.

  In fact, not only those who did not understand magic, but even real magicians could not understand Jia Lan's methods, because these skills were not the product of this era.

  Therefore, the mercenaries of Iguana Fang were full of awe for this mysterious young magician.

  The old thief tried every potion, and although he was exhausted and out of breath, he was full of excitement in his heart, as if he had returned to the time when he was adventuring side by side with his companions.

  Old Jimmy's eyes flashed, and he laughed: "It seems that my previous skills are not lost!" After that, he ran into the room and rummaged through the boxes to find a large wooden box covered with dust.

  Dave wanted to help, but was rejected by Old Jimmy.

  He deftly unlocked the complicated lock on the wooden box with one hand and took out a bunch of old but well-maintained equipment: a pair of sharp black iron daggers, a set of exquisite thief tools, and some small gadgets that only thieves know the use of.

  Old Jimmy stroked the daggers like a treasure, while the three old mercenaries stood in a row behind him, guarding his back as they did when they fought side by side.

  The faces of the old men were filled with excitement and envy, silently watching Old Jimmy take out the items in the box one by one, wipe them clean and put them on.
