Among many wizard potions, Dragon Blood Potion is considered a very special one.

    Its effect is to strengthen the body’s constitution.

    Even for formal knights, it is effective.

    It is special because the difference between the upper and lower limits of Dragon Blood Potion can be extremely disproportionate.

    Low-quality Dragon Blood Potion doesn’t even have a grade and can only be considered a zero-grade potion.

    But high-quality Dragon Blood Potion can even reach the level of tier three, tempting even full-fledged wizards.

    The potency of the Dragon Blood Potion mainly depends on the quality of its main ingredient, dragon blood.

    The higher the quality of the dragon blood, the better the effect of the potion, and naturally, the higher the grade.

    However, let alone real dragon blood, Su Nan currently doesn’t have the means to acquire even the blood of slightly stronger draconic species.

    But there are substitutes.

    Thousands of years ago, the ancestors of the Black-scaled Lizardmen were descendants of dragonkind and carried dragon bloodlines.

    Although the dragon bloodline in the Black-scaled Lizardmen has become extremely thin today, there is still some dragon blood.

    Su Nan’s goal is to extract dragon blood that meets the material standards for Dragon Blood Potion from the Black-scaled Lizardmen blood.

    Patting his cheeks, Su Nan geared himself up to start the task.

    However, just moving the heavy lizardman corpse onto the operating table left him breathless.

    “Once I make the Dragon Blood Potion, I must take it myself first to enhance my constitution!”

    After catching his breath, Su Nan picked up the scalpel to start dissecting and extracting blood.

    These Black-scaled Lizardmen had just died not long ago, and their corpses were preserved with drugs, so the blood had not coagulated, making the extraction process very smooth.

    After over an hour, having extracted all the lizardmen’s blood, Su Nan began the process of bloodline extraction.

    【Completed a blood purification, ‘Biological Modification’ learning progress +0.01%】

    【Completed blood refining, ‘Biological Modification’ learning progress +0.01%】

    【Completed bloodline extraction, ‘Biological Modification’ learning progress +0.03%】

    After multiple purifications and refinements, a large barrel of blood was ultimately reduced to just over three liters.

    Gazing at the blood in the glass, thick like gelatinous crimson, Su Nan’s eyes flickered slightly.

    【Dragon Lizard Blood, purity 35.68%, contains a dragon lizard bloodline. After injection into the body, there is a very small chance to mutate into a Dragon Lizard body, but a high chance of rejection reaction, and in severe cases, can lead to death. The stronger the constitution, the higher the mutation success rate, the lower the rejection reaction.】

    “With my current skills, reaching this level of refinement is already the limit.”

    Su Nan sighed.

    Bloodline extraction and refinement belong to a part of Biological Modification.

    He has not even mastered the skill of Biological Modification, so his skills are naturally limited.

    Fortunately, he has the Synthesis Cube as a cheat.

    “Making a portion of Dragon Blood Potion requires 80 milliliters of dragon blood.”

    Su Nan separated two portions of 80 milliliters of Dragon Lizard blood, placing them into the cube, and the synthesis interface quickly displayed the relevant information.

    【Dragon Lizard Blood, purity 51.59%, contains a dragon lizard bloodline, injected into the body, there is a small chance to mutate into a Dragon Lizard body, high chance of rejection reaction, in severe cases, can lead to death. The stronger the constitution, the higher the mutation success rate, the lower the rejection reaction.】

    “Still not enough.”

    Su Nan successively put more Dragon Lizard blood.

    The purity of the synthesized product continuously increased, but the rate of improvement decreased substantially towards the end.

    Not until the 8th portion of Dragon Lizard blood was added did the product’s information finally exhibit a qualitative change.

    【Sub-Dragon Blood, purity 1.12%, contains dragon bloodline, injected into the body, there is a very small chance to mutate into a Sub-Dragon body, but a high chance of rejection reaction, and in severe cases, can lead to death. The stronger the constitution, the higher the mutation success rate, the lower the rejection reaction.】

    “Finally succeeded.”

    Su Nan’s face showed a delighted smile.

    Sub-Dragon Blood is the minimum standard material for crafting Dragon Blood Potion.

    Considering that the first time making the potion might have a high failure rate, Su Nan thought about it and decided to prepare several sets of materials and did not continue to synthesize.
    Ultimately, with more than three liters of Black-scaled Lizardmen blood, a total of 5 portions of Sub-dragon Blood were synthesized.

    Su Nan did not immediately start making potions but instead meditated to restore his energy to peak condition before beginning the potion-making process for the first time.

    The most crucial ingredient for the Dragon Blood Potion is dragon’s blood; the other materials are easier to find, and Su Nan had already prepared them.

    He lit an alcohol lamp, placed a beaker, added water, and sequentially added materials.

    The entire process was not much different from refining Silver Moon Flowers, except for an additional final step.

    In the bright candlelight, Su Nan flicked his finger, instantly sending a bluish-purple halo into the beaker.

    His lips moved slightly, and he whispered a string of bizarre syllables, sometimes sharp and high-pitched, sometimes low and weak.

    As his voice changed, the crimson liquid inside the beaker transformed into various shapes.

    A true potion, even a zero-rank one, requires mental guidance during its creation, or failure is inevitable.

    This is why wizard potions are mysterious and powerful.

    More than ten minutes later, the crimson liquid gradually calmed down, and its volume slowly decreased.

    But at a certain moment, the liquid suddenly boiled violently, emitting a lot of green smoke, and with a bang, it turned into a mass of blackened powder.

    【Completed potion-making attempt (failed), Potion Making proficiency +4】

    “Even a failed potion-making attempt increases proficiency far more than extracting Silver Moon Flowers.”

    Su Nan showed no sign of frustration.

    He didn’t expect to succeed on his first attempt at potion-making.

    After resting for a while, Su Nan continued with a second potion-making attempt.

    Yet this also ended in failure.

    The subsequent third potion-making attempt also resulted in failure.

    Su Nan summarized the experiences from the three failures and finally succeeded on the fourth attempt.

    【Completed potion-making attempt, Potion Making proficiency +12】

    【Sub-grade Dragon Blood Potion (Zero Rank/Inferior), can enhance physique upon consumption; the extent of enhancement depends on the consumer’s physique. The weaker the physique, the stronger the effect. Effects weaken with repeated consumption.】

    “Just a Sub-grade Dragon Blood Potion?”

    “Considering the low purity of Sub-dragon Blood, achieving success was already quite good.”

    Without a second thought, Su Nan drank the potion.

    The moment the potion entered his stomach, a surge of heat exploded, instantly spreading through his entire body.

    Su Nan felt as if his whole body was immersed in scorching magma, a mix of intense pain and an uncontainable sense of joy.

    It wasn’t until four or five minutes later that the intense pain gradually subsided.

    Su Nan was drenched in sweat, as if he’d just been fished out of water, his clothes soaked through.

    Yet at this moment, he felt invigorated, like he couldn’t use up all his strength, completely rid of his previous feelings of weakness.

    Removing his shirt, Su Nan looked down at his body.

    The previously skinny body, where ribs were clearly visible, had become significantly stronger.

    Pressing lightly against his abdomen, he could clearly feel the abs beneath a thin layer of fat.

    Making a fist, his arm immediately displayed distinct muscle lines.

    Su Nan checked his stats and was pleasantly surprised to find his physique had increased from 0.7 to 2.6.

    An increase of 1.9!

    “A physique of 2.6, roughly equivalent to a novice knight who has trained for four or five years.”

    Su Nan was filled with amazement.

    A single potion transformed him from a frail ordinary person into a powerful novice knight.

    This is the power of wizard potions!

    And this is only an inferior zero-rank potion.

    If it were a high-tier Dragon Blood Potion, it might make an ordinary person directly become a knight!

    “Advanced potions are still too distant for me, but having a Sub-grade Dragon Blood Potion is enough for now.”
