Among the many wizard potions, dragon blood potions are quite special.
Their effect is to strengthen the human body.
Even formal knights are affected.
What makes them special is the extreme disparity in the quality of dragon blood potions.
Low-quality dragon blood potions don't even have a rank; they're only considered rank zero.
High-quality dragon blood potions, however, can reach rank three, making even formal wizards covet them.
The rank of a dragon blood potion primarily depends on the quality of its main ingredient, dragon blood.
Higher-quality dragon blood produces better potions, resulting in a higher rank.
However, let alone true dragon blood, even the blood of a slightly stronger sub-dragon species is beyond Su Nan's current capabilities.
But there are substitutes.
The ancestors of the Blackscale Lizardmen were descendants of dragons tens of thousands of years ago, and dragon blood flows in their veins.
Although the dragon bloodline within the Black-Scaled Lizardmen has been diluted to an extreme degree over time, it still retains traces of dragon blood.
Su Nan's goal was to extract dragon blood from the Black-Scaled Lizardmen's blood to meet the standards for dragon blood potion ingredients.
Patting his cheeks, Su Nan braced himself and prepared to begin.
However, just the first step of moving the heavy lizardman corpse onto the operating table left him breathless.
"Once I've made the dragon blood potion, I must take it myself first to improve my physical condition!"
Calming his breathing, Su Nan picked up a scalpel and began dissecting and extracting blood.
These Black-Scaled Lizardmen had only recently died, and their bodies had been preserved with medication, so the blood hadn't yet coagulated, making the blood extraction process very smooth.
After spending over an hour extracting all the lizardmen's blood, Su Nan then began the bloodline extraction process.
[Completed one blood purification, 'Biological Modification' learning progress +0.01%]
[Completed one blood refining, 'Biological Modification' learning progress +0.01%]
[Completed one bloodline extraction, 'Biological Modification' learning progress +0.03%]
After multiple purifications and refinements, a whole barrel of blood was reduced to just over three liters.
Looking at the viscous, jelly-like crimson blood in the glass, Su Nan's eyes flickered slightly.
[Dragon Lizard Blood, purity 35.68%. Blood containing the dragon lizard bloodline has a very small probability of mutating into a dragon lizard body after injection into a human and a very high probability of a rejection reaction, which can lead to death in severe cases. The stronger the physique, the higher the mutation success rate and the lower the rejection reaction.
"With my current technology, this is the limit of what I can achieve."
Su Nan sighed.
Bloodline extraction and refining are part of biological modification.
He hasn't even mastered biological modification skills yet, so his technology is naturally limited.
Fortunately, he still has the Synthesis Cube as a cheat code.
"Making one Dragon Blood Potion requires 80 ml of dragon blood."
Su Nan separated two 80 ml portions of dragon lizard blood and placed them into the Rubik's Cube. The corresponding information quickly appeared on the synthesis interface.
[Dragon Lizard Blood, Purity 51.59%, blood containing the dragon lizard bloodline. After injection into a human, there is a small probability of mutation into a dragon lizard body and a high probability of a rejection reaction, which can lead to death in severe cases. The stronger the physique, the higher the mutation success rate and the lower the rejection reaction.
"Not enough."
Su Nan continued to add more dragon lizard blood.
The purity of the synthesized product increased continuously, but the rate of increase decreased with each addition.
Finally, after adding the 8th portion of dragon lizard blood, the information about the synthesized product underwent a qualitative change.
[Dragon Blood, Purity 1.12%, blood containing dragon bloodline. After injection into a human, there is a very small probability of mutation into a dragon body and a very high probability of a rejection reaction, which can lead to death in severe cases. The stronger the physique, the higher the mutation success rate and the lower the rejection reaction.
"Finally succeeded."
A joyful smile appeared on Su Nan's face.
Dragon blood is the minimum required ingredient for crafting dragon blood potions.
Considering the potentially high failure rate of his first attempt, Su Nan decided to prepare several batches of the material and refrain from further synthesis.
Ultimately, he synthesized five portions of dragon blood from over three liters of Blackscale Lizardman blood.
Instead of immediately starting the potion-making process, Su Nan meditated to restore his energy to its peak before beginning his first attempt.
The most important ingredient in Dragon Blood Potion is dragon blood; the other ingredients are easy to find, and Su Nan had already prepared them.
He lit the alcohol lamp, placed the beaker, added water, and then added the ingredients in order.
The whole process was similar to refining Silver Moon Flower, except for an extra step at the end.
Under the bright candlelight, Su Nan flicked his finger, and a point of blue-purple light instantly disappeared into the beaker.
At the same time, his lips moved slightly, uttering a series of strange syllables, sometimes sharp and high-pitched, sometimes low and weak.
With his voice, the bright red liquid in the beaker changed into various shapes.
Real potions, even zero-level ones, require mental energy as a guide during the creation process; otherwise, they will inevitably fail.
This is the reason why wizard potions are mysterious and powerful.
More than ten minutes later, the bright red liquid gradually calmed down, and its volume slowly shrank.
But at a certain moment, the liquid suddenly boiled violently again, emitting a large amount of blue smoke, and after a bang, it turned into a ball of charred powder.
[Completed one potion-making attempt (failed), potion-making proficiency +4]
"Even with a failed potion-making attempt, the increased proficiency far exceeds that from extracting Silver Moon Flower."
Su Nan showed no sign of frustration.
He hadn't expected to succeed on his first attempt.
After resting for a while, Su Nan continued with his second potion-making attempt.
However, this attempt also ended in failure.
The third attempt also failed.
Su Nan summarized the lessons learned from the three failures and finally succeeded on his fourth attempt.
[Completed one potion-making attempt; potion-making proficiency +12]
[Lesser Dragon Blood Potion (Tier 0/Low Grade)] strengthens physique after consumption. The specific degree of strengthening depends on the user's physique; the weaker the physique, the stronger the effect. Repeated consumption will weaken the effect. "Just a Lesser Dragon Blood Potion?
"That's true. After all, the purity of the sub-dragon's blood is too low. It's already quite good that I was able to make it successfully."
Without saying a word, Su Nan poured the potion into his mouth.
The moment the potion entered his stomach, a surge of heat exploded, instantly coursing through his limbs and bones.
Su Nan felt as if he were immersed in scalding lava, experiencing excruciating pain mixed with a strange, almost unbearable, thrill.
Four or five minutes passed before the pain slowly subsided.
Su Nan was drenched in sweat, as if he had just been pulled from the water, his clothes completely soaked.
Yet, at this moment, he felt incredibly energetic, as if he had inexhaustible strength, completely unlike the previous feeling of weakness and exhaustion.
Taking off his shirt, Su Nan looked down at his body. His
previously thin frame, where his ribs were clearly visible, had become much more toned and muscular.
Pressing his hand lightly on his abdomen, he could clearly feel the abdominal muscles beneath the light fat.
Clenching his fist and exerting force, his arms immediately revealed distinct muscle lines.
Su Nan opened his data panel and was pleasantly surprised to find that his constitution had increased from 0.7 to 2.6—
an increase of a full 1.9!
"A constitution of 2.6 is roughly equivalent to a trainee knight who has cultivated for four or five years."
Su Nan exclaimed in amazement.
A single potion transformed him from a frail, ordinary person into a powerful apprentice knight.
That's the power of wizard potions!
And this was merely a low-grade, rank zero potion.
If it were a higher-grade Dragon Blood potion, it might have allowed an ordinary person to directly advance to knighthood!
"High-grade potions are still too far beyond my reach; for now, this lower-grade Dragon Blood potion is sufficient."
