"What if I were to enter the Grand Library when I'm injured? Even if time flows at a constant rate, wouldn't ten days be better than one for getting treatment?" Tang Don thought of another possibility.

  "Yes, you can take advantage of your time in the temple to recover from your injuries, but remember that no medicine will be effective, and you can only use spiritual techniques to heal your body."

  Homa finally brought some good news.

  Almost all healing spells are harmless, but the potions are different. When the body grows steadily, metabolic activity slows down, which also means that the absorption of potions slows down, causing them to accumulate in large quantities in the body and produce adverse reactions on muscles and organs.

  "It seems I don't even know a healing spell?" Tong Dun was stunned, and then felt regretful. As a wild Holy Knight, he really didn't understand how to systematically learn spells, completely relying on what was needed in battle to go and sacrifice.

  The ancient altar, the extinguished divine fire altars in the plane of magic, and tens of thousands of undead creatures in the underground city. These three key points are necessary for Tang Don to obtain divine spells through sacrifice; otherwise, he can only learn like other paladins, step by step.

  "You've just realized that?" Holma teased, "A Holy Knight like you who can't even be considered a half-baked one, if you go to the secret realm or ancient ruins for adventure, any adventurer group won't even give you a glance, let alone recruit you."

  "Whatever, I'll deal with the divine magic after I leave the library. For now, let's start my potion-making course!" Tang Dong thought about how he still owed cheap gods a lot of soul offerings and could only suppress his thoughts of making another offering.

  "This is your reading list for next time."

  The magical flames flickered, forming a dense row of book titles, nearly a hundred volumes.

  "Pharmaceutical Introduction", "Magical Medicine Properties Compendium", "Practical Magical Pharmacy", "One Thousand Kinds of Wonderful Magical Medicines", "Thousand Kinds of Commonly Used Pharmaceutical Preparations"

  With a loud crash, the fist-sized book spirit popped out of thin air, with a slightly yellowed parchment floating in front of it and a pure white goose feather pen.

  "Is that all?" The book spirit blinked its big eyes and asked in a soft voice.

  "Hmm!" Dongton nodded.

  As a being comparable to a great encyclopedia, Holma's experience is too rich, and the list of magical medicine books he has listed is absolutely the most efficient and practical at present.

  "Check out accepted!"

  As the voice of the Book Spirit fell, the goose quill pen tapped twice in mid-air, as if dipping into ink, and then began to write on the sheepskin paper with purple iris flower decorations, leaving a string of magnificent magic flame characters.

  Every time a book title is written, it flashes like a star, and the corresponding book seems to have grown wings, flying out of the bookshelf.

  Serena woke up to see books falling onto the table in front of Tangdon, piling up into high stacks like migratory geese returning north.

  Dangton picked one up, opened the cover, and although the book wasn't very new, it was well-preserved, with no signs of damage or folded pages.

  "Return on time and take good care of the book, otherwise you will be punished!"

  After mentioning a dozen or so precautions, with a "poof" sound, the Book Spirit vanished into thin air.

  "Go read a book, I won't disturb you. If you have any questions, you can ask me or the Book Spirit!" Mo Dian released paper and pen from the War Space, along with an ink bottle, and flew towards Serese, "Let's go to the other side of the district."

  Ceres was unwilling, and as a result, he was slapped hard on the forehead by Mo Dian, scolded, and then left obediently.

  Dunton's hands as he opened the book had a slight tremble, and he thought of when he was young and sat with his sister under the oil lamp, listening to their mother read.

  The goose quill pen kissed the sheepskin paper, issuing a soft and rhythmic rustling sound, like the tender green shoots of spring, full of youthful dreams, bursting forth from the earth.

  Time flies like an arrow, and Tang Don remains at his desk, but his posture has never changed.

  Looking at Tondon eating black bread with his mouth and his eyes never leaving the book page, Holma felt very relieved. In the past ten days, he had seen this state many times, and it was not a sudden impulse, but a real desire to become a great pharmacist.

  "This focus and hard work will bring you a bountiful harvest." Holma sighed, not daring to disturb him, flew away, just let him see the last moment.

  With Serenity's lively personality, she couldn't bear to sit quietly and read books, but every time she went to find Danton, she saw him holding a book, absorbing knowledge, as if he were a statue, and the Death Witch's lips had opened many times, but in the end, she didn't disturb him.

  "At least, keep up with Tandon's pace!" Inspired by this scene, Seres began to work hard and secretly made up her mind.

  There were two diligent students, Holma was very satisfied and then strictly took on the role of mentor, teaching Seres with all her might.

  Bang! A loud explosion sounded, and the Book Spirit appeared out of thin air.

  "Your borrowing time has expired. Please leave the library within five minutes, otherwise you will be subject to forced eviction and deprivation of next borrowing qualification."

  Business is business; the Bookman won't change his opinion of Downton just because he's trying.

  "So soon?" Tang Don stretched his waist, feeling that his body was about to rust, and his muscles were slightly sore.

  In ten days, Tang Dun left his seat a countable number of times, and it was inevitable that his body would become stiff. If he weren't a mage, he wouldn't have been able to hold on.

  Seris held the Grimoire in her arms and flew over.

  "Next time remember to balance work and rest, when you're tired stand up and move around a bit." Holma projected the text, "Let's go."

  "Thank you!" Downton reluctantly closed the book, tidied up the table and thanked the librarian.

  "This is my duty!" The book spirit, due to Tang Dun's attitude, rarely added another sentence, "Do you need to borrow books to take away?"

  "You mean I can take the book out?" Danton was taken aback for a moment, then overjoyed, nodding hastily, "I need it."

  "You have E-class clearance, you can borrow one book to take out of the library, but please keep it safe. If it's damaged, you will suffer severe punishment." The Book Spirit added, "The borrowing time is determined by the amount of magic stones you pay."

  "Help me with that, and I'll lend you this 'One Thousand Kinds of Magical Medicine'!" As for paying with magic stones, Tang Dong didn't show any surprise or complaint. There's no such thing as a free lunch in the world, it's just basic common sense.

  "Good choice, now you should quickly memorize various potions, otherwise buying fake goods will waste gold coins, but the key is too embarrassing." Holma knew these knowledge, but it was hers, if Tongdon couldn't remember them, he wouldn't even have the qualifications to step into the door of potion studies.

  Out of the library, along the stairs, Tong Dun retreated back to his study, the Gothic gate behind him shattered into a flowing light, flying and drifting down.

  Feeling the weight of the book in his hand, Tang Don had an unreal feeling, and the magical power of the Demon Scripture was indeed incredibly strong.

  "Get ready, continue to attack the bank, hunt down spiders, and pay off the debts first." Mo Dian had already arranged the plan in an orderly manner.

  Tang Dun walked into the yard, looking at the dim underground city, took a deep breath, "Homa, arm me, release the magic servant!"

  The war space opened, and six elemental arms held the components of the 'Hundred-Man Warrior' armor to help Tondon put it on. At the same time, four ghouls wearing warrior suits stepped out of the light gate and stood around.

  One of them had a battle-axe with dragon-tooth serrations on its back.

  With the warrior's shortsword at his waist, Thronton carried the cannibalistic orcish scimitar towards the central district where the largest bank of the underground city Polusna was located.

  In front of the bank stood a stone monument, on which was carved the coat of arms of the House of Hohenzollern, hereditary princes of Sigmaringen, a name that represented wealth, power and influence.

  "I hope the treasures in the treasury won't disappoint us." Danton swung his military sword, chopping at the black blood spiders surrounded by the magic servants.

  "Why are there so many spiders?" Seres looked at these insects, which were bigger than war horses and had ferocious mouthparts and compound eyes, and felt nauseous, hiding far away and refusing to scout ahead.

  With the bank as the center, the entire street was covered with white spider webs, and piles of water bucket-sized spider eggs were scattered unevenly among them.

  Except for the black blood spiders that left their bank nests to hunt, the rest were scattered on the long street, guarding their spider mothers.

  "Don't rush, advance slowly. These spiders are more difficult to deal with than the miscellaneous fish and vengeful spirits." After discussing it with Mo Dian, Tang Tuo gave up on the idea of using fire. Once the fire started, not only would it be hard to control, but it would also attract a large number of undead creatures. If there were a few high-ranking ones mixed in, Tang Tuo would definitely be done for.

  Of course, the biggest hidden danger is still the Robinson trio. If they notice the bank because of the flames and come to rob the vault, not a single hair on Downton's head will be spared.

  "Maybe there's legendary-level equipment inside!" Tong Dun loaded his crossbow and fired at the nearest spider.

  The crossbow bolt hit the spider's body, and with a burst of fresh blood, it scurried over quickly.

  Fortunately, there aren't many dark creatures living in the underground city, which also means a lack of food, preventing the black blood spider's tribe from growing stronger. Otherwise, Tangdon would never have dared to rob the Hohenzollern Bank, which had already become a spider's nest.

  Danton continued to shoot arrows, and at any moment he was ready to send out a ghoul to harass the spider, ensuring that it would not give up the chase. As soon as they turned the corner, the prepared demonic servants rushed forward fearlessly.

  "It's still not safe, and it's too slow!" After killing the spider and collecting the magic core, Tang Dong didn't rush to summon monsters, but instead calmly thought.

  "What's to be done?" Serres was very dependent on Tongdon and didn't even bother to think for herself, she thought Tongdon must have a solution.

  "You'll see soon enough." Downton didn't disappoint.

  A pair of eyes glowing with a dark red light was staring at Tang Don's every move through a narrow window slit, then stuck out a scarlet tongue and licked his lips.

  After searching for half a day, Tony Dutton was found hiding in a safe civilian house, sleeping soundly on a wooden bed.
