The mystical tome was given to Tandon's experimental building, named The Hive.

  It's very large, with a full 26 floors, but there are some areas that Tang Don can't enter due to permission issues. However, the over 100 rooms of various functions that he can use have already satisfied him.

  As for memorization, Tongdun never had any trouble. He spent only two hours to commit the entire thick laboratory manual to memory.

  Standing at the door of the pharmacy, looking at the neat and tidy room, Tang Don took a deep breath.

  "Congratulations, you've become the new owner of the Hive Laboratory." Mo Dian congratulated. The previous owners weren't very interested in magical medicine, so this place has been abandoned for a long time. Now it can be used again, and it won't be a waste of a precious gem.

  "Thank you." Downton was slightly excited, "What now? What is the prescription of the medicine you are going to give me?"

  "Mana Extraction Potion!"

  The magical characters flickered in the air, lined up neatly as Danton explained in detail, "It's a supplementary medicine, drinking it half an hour before meditation can increase the body's absorption rate of magic."

  Each Meister has a different rate of absorption when it comes to magical energy, the faster and more they absorb, the higher their meditation efficiency.

  Tang Dun's qualifications were above average, surpassing most people, but compared to some naturally gifted geniuses, he still fell short. However, due to his resemblance to the Saintly Meditation Method, his meditation efficiency was not slow either. Moreover, his willpower was tenacious, and when he became a Magic Practitioner, he condensed a powerful Soul Seed. All of these would allow him to gradually catch up with those geniuses in his future cultivation.

  "I know, it's in high demand and is one of the top ten best-selling medicines." Danton let out a wry smile. "I even thought about buying some for Irene before, but one vial costs 100 gold coins. Even if I worked non-stop for a month, I wouldn't be able to afford one."

  Ordinary mages want to improve efficiency and save time, what should they do? Of course, use potions as a supplement. Mages extracting potions is undoubtedly the best choice.

  It can be said that any mage with a bit of spare money will always have this potion on hand.

  "Now with your purse full, you can completely buy them back and use them as bath water." Mo Dian comforted, knowing that the previous Tang Don had suffered a lot.

  "Hmm, if I can successfully create a qualified magical energy extraction potion, I'll be set for life and never have to worry about food or clothing again."

  "Commoners, don't be like a mediocre person who just eats and waits for death, have some ambition and ideals, okay?" Mo Tian complained. "No matter what you want to do, you must stand at the peak, otherwise it's too humiliating for my Lord Horma."

  "Our reserve gold is far from enough, those gold bars look like a lot, but when converted to magic diamonds, not even one hundred can be bought." Tang Dun thought about the future, apart from his own consumption, Irene and Serese also had to be taken care of.

  To cultivate a dragon-slaying mage, besides talent and hard work, various resources cannot be lacking. At the very least, magic stones and nutrition must keep up, and a full set of equipment needs to be prepared. Otherwise, before growing up, they will die in the trials.

  "Even if selling potions is profitable, I wouldn't choose this kind, it's too degrading. I'd rather choose top-grade potions, with just one bottle, I can make tens of millions of gold." Mo Dian pursued speed, selling magic potions and the like, in his eyes, it was as slow as picking up copper coins one by one.

  "Do you have the formula?" Tong Dun's eyes lit up.

  "That formula for the giant dragon's guardian potion isn't bad, when the time comes to make it, just throw it into the auction house and people will definitely go crazy bidding sky-high prices." Mo Dian reminded, "I do have some formulas, but considering your level, studying those would be a waste of time. So, I'll give you the most practical ones for now, and the difficulty of the formulas will gradually increase according to your level."

  "I believe in you." Tong Dun felt at ease, the Magic Book was comparable to a great encyclopedia, its set learning course must be the most optimized and efficient. "What to do now?"

  "Classify herbs, make simple processing, convenient for preservation, and then start familiarizing with the most basic laboratory operations." Holma listed a large table.

  The war space opened at the same time, and the bronze big hand took out all the herbs and piled them up in the medicine room.

  The use of various magic balances, the use and cleaning of glass instruments, the configuration of various attribute washing liquids, as well as the configuration of commonly used basic solutions such as buffer solutions and energy storage solutions, are all necessary to master.

  Tang Dun held a volumetric flask, silently reciting the scale on it, and found that mathematical knowledge was also essential. Otherwise, even the required concentration and ratio values couldn't be calculated.

  "Alchemy is a comprehensive subject, to master it, you need to grasp a lot of knowledge, it's too time-consuming, so I don't suggest you learn it." Holma just said it casually, she knew Tangdon's personality, he would absolutely not give up.

  "That means less sleep, I can handle it." Downton sorted through the medicinal herbs, picking out those that needed to be stored in a cool, dry place first. "Is there any medicine that can keep me awake for a week straight and still feel energized?"

  "Do you want to die of exhaustion?" Holma was shocked, she didn't expect Danton to come up with such a drastic measure.

  "I'm still young, nothing will happen." As for the dark circles under his eyes, Tang Dun didn't care about that at all. "So, does that mean there's a similar medicine?"

  "There is, but I absolutely won't give it to you, it will harm your body." Mo Tian refused decisively.

  "Lord Holm, please accept my knee!" Tanton's rare soft words were coquettish, "Those genius nobles are all cultivated from a young age, I've already missed out on over a decade of time, if I don't desperately run, how can I catch up to them?"

  "There's no medicine, but I have other ways to extend the time." Holma compromised, and Tondon's ferocity really moved her. She felt that if she didn't help him, she might regret it later.

  "What method?" Tong Dun's mother was too anxious and accidentally put in the wrong herbs.

  The bronze giant grasped the whip and lashed out at Tong Dun's back with a loud crack, causing him to gasp in pain.

  Inside the hive, there is an independent laboratory that was renovated by the 17th master. It has fixed the time principle, flow rate and the ratio of the western continent's surface, which is ten to one!

  "Just like the Grand Library." Tang Don was delighted, which meant that he had spent ten days in the hive, while only one day had passed in Frankfurt. "Right, what about the time flow rate on me?"

  "Keep in sync with the Western continent, so you don't have to worry about growing faster than Irene." Holma sighed, "But opening an independent laboratory requires burning a large amount of magic stones as a power source. The twenty crates of magic stones you got from the bank can last at most thirty days, yeah, Westland time."

  "Such a huge consumption?" Tong Dun was shocked, this laboratory is simply a gold-eating monster, converted into numbers, the amount of gold coins consumed every day is astronomical.

  "Enjoy your secret pleasure, the magician who has mastered the Time Law, is already standing at the pinnacle of the entire continent. Such a strong person can be counted on one's fingers, and just from the fact that this laboratory can fix the Time Law, its value is immeasurable." The Magic Book didn't forget how much effort and wealth the 17th master spent to build this laboratory, enough to trigger a small-scale inter-planar war.

  "Praise the goddess!" Tanton felt that he was favored by the goddess of fortune, money and time, people will always choose the latter.

  "But the most troublesome thing is not the magic stone problem, but after you enter the laboratory, you are not allowed to use any martial skills or divine techniques, and you are not allowed to let the magical energy in your body fluctuate." Mo Tian warned, "Just treat yourself as an ordinary person."

  "Why?" Tanton was puzzled, "I thought I was still practicing in the lab?"

  "Stop daydreaming." Holma gave the answer, "The laboratory is located in a special location, surrounded by many very dangerous monsters. If the magical fluctuations attract them to you, you're dead for sure."

  "Can't run away?"

  "The transmission process takes five minutes, you can't escape." Holma projected a piece of lava, "You can understand it as sitting on the mouth of a volcano that may erupt at any time to conduct experiments."

  The MoD is hiding some facts and if they were to come out, it would scare Downton.

  "Shall we go now?" Tang Dun didn't want to waste a single second, and as for the magic stone, it could be earned again after being used up.

  The lighting and water supply systems of the hive need to be inspected, apart from Mo Dian, no one else can do it. Although the work is heavy, she did not refuse Tang Dun's proposal.

  "Alright!" Mo Tian put away the herbs and took Tang Dong to the sixth underground floor.

  "Why is there still a dungeon?"

  Carrying a lantern, Thaddeus descended the spiral staircase and entered the underground corridor, where he saw those bloodstained dungeons, even some skeletons of magical beasts, shackled in chains.

  "They were all experimental subjects, materials for the dark arts." Holma was an aesthete, so this was also one of the reasons she disliked dark magic, because some experiments were filled with bloody and cruel auras that didn't conform to her aesthetic views.

  After walking for twenty minutes, Tandon stopped in front of a black metal door with dense magical patterns engraved on it, the complexity of which was enough to make a dragon-slaying mage unable to decipher its meaning, holding Holma in one arm.

  This was a hundredfold locked magical door, and even Horma's strength took a full ten minutes to open it.

  Danton exclaimed, bursting into view was a semi-transparent blue circular tunnel, surrounded by countless "light spots" that twinkled like stars.

  "Let's go!" The magic book fell back into Tanton's hands, urging him forward.

  "Thanks, Homura!" Tadokoro walked quickly, a heartfelt thanks to the Grimoire. Without it, he wouldn't have all that he had now, nor would he be able to touch so many mysterious and beautiful worlds.

  Although Downton didn't stop Mo Ye from calling himself the master, he never treated Holma as a servant but rather as a mentor and friend.

  "Hmph, this time opening an independent laboratory will consume a large amount of magic stones. If you can't learn to configure the magic energy extraction potion, just wait for punishment!" Holma projected an arrow that poked Tangton's forehead, and immediately turned into burning text warning, "Be careful, there's trouble."
