"The little girl sold us expired medicine, causing one of our team members to fall ill. Now we have to compensate her, it's only fair."

  In the Wolf and Spice Bazaar, the air solidified because of Tandon's displayed equipment, making Scarface mercenaries speak carefully, no longer daring to scold hybrids.

  "Where is the remaining potion? I am also a pharmacist, I can do the test. If you guys are lying, I will make you pay the price." Tang Don glanced at the broken bottle on the ground and the surrounding water stains, not believing these guys' words.

  "Can't you hear me telling you to scram? Don't think that just because you're well-equipped, you can be arrogant." A mercenary's eyes gleamed with a fierce light as he activated his Soul Shield, two semi-transparent orbs spinning around his body.

  "Master, what's the point of talking to these trash fish? Let's just kill them off." Jackson's eyes gleamed with a green light, his killing intent radiating in all directions. His left hand grasped the military knife and handed it over to Tandon, while his right hand reached behind his waist, gripping the handle of the crossbow, ready to launch a sneak attack at any moment.

  "Can you appraise the magical potion? Deceive the undead? I've never seen a young potion master like you." The scar-faced mercenary felt a bit guilty, mainly because Tang Dong was too calm. If it were an ordinary youth, they would have been scared out of their wits.

  "I'm telling you again, put things back to their original place!" Tong Dun drew out his military saber and also activated the Soul Shield. Here in Chen Yu Town, he wanted to avoid fighting as much as possible, or else Li Si Te would have enough excuse to bother him.

  "Soul Three Stages? I didn't see it wrong?"

  "Who is this Emperor Taizong? He's even higher in rank than I am!"

  "What's he afraid of? Can't he take on three by himself?"

  "Haha, are all humans so arrogant?" Jackson teased, eager to jump in. "Master, you don't need to take action, let me do it? But the brains and internal organs must be left for me to eat, I've been starving for a long time!"

  Three mercenaries immediately felt their hair stand on end, despite Jackson being wrapped in bandages, but those green eyes still showed its non-human identity.

  This should be a vengeful spirit!

  The three mercenaries exchanged a glance, silently understanding each other as they dropped the medicine and attempted to leave.

  Dundon's sword flashed horizontally, blocking the doorway. "I said put things back where they belong."

  The scar-faced mercenary was about to curse loudly, but a crossbow bolt suddenly pressed against his temple, forcing him to swallow the foul language again.

  Jackson jerked his head, indicating for them to tidy up the disordered store.

  "Listen up, kid. You're lucky. Don't let us run into each other again, or we'll show you some colors." Five minutes later, the three mercenaries finally walked out of the convenience store.

  The scar-faced man was cursing loudly, but the next second he shut his mouth in shock, as a crossbow bolt whizzed past his forehead.

  "We don't sell expired medicine." Seeing Tong Dun defending himself, the female shop owner hadn't felt such warmth from being cared about for a long time, and she revealed a hint of a smile, explaining that she didn't want to be misunderstood.

  "Uh-huh, I know. Here, this is for you." Tongdon put the apple on the table, his mind a jumble of confusion, unable to think of anything to say, and simply turned around and left.

  The female shop owner looked at the magic book in Tang Don's hand, glanced at his back, and sighed. "Are you studying potion-making? Although I'm just an ordinary potioneer, if you encounter any difficulties, I might be able to help you solve them."

  Dangton stopped in his tracks, never expecting the situation to suddenly turn around.

  "My name is Xia Luo!" said the wolf and spice shop owner, "What's yours?"

  "Dundun!" Dundun tensed up, using the topic to cover his emotions, "It's the same name as the Harvest Goddess of the Bimon beastmen!"

  The Beastman tribe, apart from worshipping the beast god, that is, the war god, also worshipped the harvest goddess Xialuo, because she taught them animal husbandry, farming and so on, imparted a large amount of knowledge to them, and brought civilization.

  Because it is said that the harvest goddess is a wolf werewolf, she is also called Xianlang, representing great wisdom and harvest.

  Some beastman tribes, and even some human nations, hold a harvest festival after the summer harvest every year to pray for blessings from Xialuo, the wise wolf, to ensure good weather in the coming year.

  Xia Luo nodded and continued to flip through the plant identification book.

  "Then I'll trouble you, apart from malachite powder, what other solvent can be used to extract the active ingredients of fish blue grass and ensure that its activity is above 75% in liquid form?" Tang Don took out his notes and quill pen, asking about the difficulties encountered during the process of configuring the improved version of the magic energy extraction agent.

  "Your question is very pointed!"

  Xia Luo was surprised. Having lived in Chenwu Town for so long, she had of course seen Tang Dun before and knew he was an ordinary commoner youth. But now he actually asked a very professional question about magic medicine, "Have you studied the methyl liquid equation?"

  "Hmm!" Dongton nodded.

  "Write it down!" Charlotte wouldn't believe Downton just because of his casual remark.

  Tang Dun did not show any stage fright, standing by the counter, dipped his pen in ink and quickly wrote on his notebook.

  Hard work in the library and efforts in the independent laboratory made Tanton's sweat worthwhile, he didn't even think about it, and succeeded at one stroke.

  "Write down the derivative formula." Xia Luo was surprised and couldn't help but take a glance at Tang Dun, only to find that this young man had already lost his earlier awkwardness and was completely immersed in alchemy. His pursed lips and focused eyes made his facial features appear softer.

  "It's this!" Tandon pushed the notebook in front of Xiao Luo.

  "Ah, completely correct, and the handwriting is beautiful." Xia Luo praised, on the slightly yellowed parchment, the Flame Script originating from the Nesseriel magical civilization was elegant and beautiful, forming an equation that was like a poem, pleasing to the eye, even if one didn't understand alchemy, they could still feel its beauty.

  "Thanks!" Downton scratched his head, feeling embarrassed.

  "Alas, it's hopeless." Seeing Tondon subconsciously show his most perfect side to Xia Luo, Mo Dian sighed, but the most beautiful magic flame characters in the history of the Western Continent were absolutely the best choice for writing love poems, because the ancient philosopher said that even if a woman doesn't fall in love with you, she will fall in love with this style.

  "Do you want to improve the mana extraction potion?" Xia Luo's words directly stunned Tang Dun, he didn't expect that his opponent could infer his purpose from just one equation.

  "The fish blue grass is the most important magic medicine for configuring the mana extraction agent, and with your limited percentage, it's easy to guess your intention." Xia Luo pushed the notebook back to Tang Don, "The mana extraction agent is too common, so how to improve its efficacy and reduce production costs has always been a topic of research for magic medicine practitioners. The Royal Pharmaceutical Association even set up a prize to reward those who can bring efficacy enhancement to the top ten best-selling medicines."

  Xia Luo just said she was an ordinary potion master, but in fact, she was being modest. She herself had won this award and her improved potion formulas were even displayed in the Formula Hall of the Royal Potion Master Association. To know that every formula that can be placed inside has had a huge impact on the world of potions.

  Of course, when Xia Luo did all this, she had changed her name; otherwise, with her identity, it would have caused big trouble.

  Tang Dun estimated that if he took out that improved medicine, he would definitely get the scholarship, but with his personality, he definitely wouldn't do it.

  "If you're interested in potion-making, you can subscribe to a copy of 'Nature', the academic journal published by the Royal Apothecary Society." Charlotte took a bite of her apple and advised, "Don't waste your time trying to improve magical extraction potions, you should read as many books as possible and learn more knowledge."

  In fact, there are many better formulas in the association, but they are not suitable for mass production, so the mages have never seen them on the market. However, among the noble families who own private alchemists, their family members drink all kinds of higher-grade potions.

  "I get it!" Tang Dun wasn't trying to improve the medicine, but the configuration process of Cui Shi powder and Yu Lan grass was too difficult to control, resulting in a high error rate in his operations, so he thought of finding an alternative.

  "Hmm, wait a minute, the activity change under liquid phase is not pursuing the highest, but keeping at a constant value." Xia Luo recalled Tang Dun's question and suddenly frowned, "Where did you see this method?"

  This is a completely new approach to drug treatment, and if it weren't for Xia Luo's genius, no one would have noticed.

  Tang Dun hesitated and looked at Mo Dian, unsure whether he should tell Xia Luo.

  "It's none of our business, you don't have to say." Xia Luo took Tang Dun's pen and wrote on the paper, listing out row after row of chemical reaction equations.

  "Tell her!"

  Homa showed the text, a formula that was worth millions or even tens of millions for ordinary magicians, but for Mo Tian, it was just a waste paper. Using it to exchange for Xia Luo's trust and favor was really worthwhile.

  Just Xia Luo's current talent in the field of magical medicine is worth investing in.

  "I have a formula." Danton has been practicing those advanced operations for some time and is already familiar with the entire configuration process, so he says readily.

  Listening to Downton's chatter, Xia Luo nodded continuously.

  Warm sunlight spilled into the store and landed on the shelves, where dust particles could be seen floating before settling on Downton and Charlo.

  Two people discussing at a desk, apples piled up together in a fruit plate, plus an ink bottle and a goose feather pen, these scenes combined together, like a oil painting of the Renaissance period, full of quiet beauty.

  "The alchemist who wrote this formula is absolutely a master!" Xia Luo looked at the process on the paper and couldn't help but praise, "It's really very talented and has a spiritual nature!"

  Downton didn't say anything, if he let Xiao Luo know that this formula had appeared more than a thousand years ago, she would be even more surprised.

  "Your generosity moves me." Xia Luo smiled, "However, I won't take advantage of your kindness, I'll also tell you a prescription for a medicine of equivalent value."

  Tang Dun just drove away three mercenaries and revealed the formula, which has already made Xia Luo acknowledge him. Although they are not friends yet, their relationship is much closer than that of strangers.
