Late at night, the moonlight was bright.

    In the meditation chamber, Su Nan sat cross-legged on the ground, staring at the panel in front of him.

    【Su Nan Anes-t, Human Male, 17 years old】

    【Mental Power 15.23/Physique 12.83】

    【Skills】

    Star Ring Meditation Technique Lv4 (12759/20000)

    Potion Making Lv3 (108/6000)

    Biological Modification Lv2 (319/3000)

    Puppet Crafting Lv2 (1701/3000)

    Almost five months have passed since I advanced to a Rank 2 Wizard Apprentice, and the proficiency of the Star Ring Meditation Technique still needs about one-third more to upgrade.

    “The speed of constructing the star ring is still too slow.”

    “When I return this time, I should try using secondary active potions to synthesize more efficient ones.”

    Su Nan pondered in his mind.

    Given his current physique and mental power, using higher-grade potions shouldn’t be a problem.

    The key is still the cost.

    As his Potion Making skill rose to level 3, his success rate for making secondary active potions also increased significantly, thereby reducing the cost of potions quite a bit.

    Now, the cost of a bottle of secondary active potion is about a little over 8 gold coins.

    Whereas synthesizing a Rank 1 low-grade active potion costs roughly 100 gold coins.

    “To significantly improve the efficiency of meditation, it would have to be at least a Rank 1 high-grade active potion, and the cost is estimated to be no less than 200 gold coins.”

    “That’s 200 gold coins a month, or 2400 gold coins a year, which is about half of Blackstone City’s annual income.”

    “If I synthesize Rank 2 potions, the cost would be at least a thousand gold coins.”

    Su Nan furrowed his brow slightly.

    Blackstone City is currently in a period of rapid development, requiring large sums of money for both expanding the army and further developing the Blackstone Mine.

    Even if Brother Ke Yi doesn’t mind, Su Nan couldn’t possibly divert too many gold coins for himself.

    After all, the growth and expansion of Blackstone City are equally important.

    “I still need to find a way to increase income.”

    Su Nan glanced at the active potions at hand, a thoughtful expression appearing on his face.

    Perhaps I could try selling zero-rank potions.

    Such as brute strength potion, healing potion, and swift potion.

    In the previous battle against the Black-scaled Lizardmen, the cavalry regiment used both brute strength potions and healing potions, and the feedback afterward was quite positive.

    If these potions are sold, I believe many knights would be interested.

    Of course, the potions sold externally must be differentiated from those used by the Blackstone City knights.

    For instance, a potion could be diluted into three bottles.

    This way, I could sell for more gold coins.

    The more Su Nan thought about it, the more feasible it seemed. He decisively decided to produce a batch of finished products before leaving and hand them over to the Fire Fox Commerce Association to test the waters.

    If the response is good enough, I can expand the scale when I return.

    As long as this trade route works, I won’t have to worry about the materials for synthesizing high-grade active potions anymore.

    “Let’s do it!”

    Feeling slightly invigorated, Su Nan got up and went outside.

    The gloomy night enveloped the entire courtyard, giving it an air of tranquility.

    Yet only Su Nan could sense that the Hidden Dragon was lying at the base of the courtyard wall more than ten meters away, sleeping soundly.

    During this time, he had performed over a dozen blood transfusion surgeries on the Hidden Dragon, forcibly enhancing its dragon-lizard bloodline by more than ten percent.

    Now, the Hidden Dragon’s dragon-lizard bloodline exceeded 35%, its body had grown even larger, and its physical strength had been upgraded to an intermediate grand knight’s level.

    Now, the Hidden Dragon could even hold its own against a peak grand knight.

    For this reason, Su Nan decided to take the Hidden Dragon along on this trip to Stone Bell City.

    With its invisibility and reality-transformation abilities, there’s no need to worry about being detected even when entering the city.
    On the road, one could have a mount to ride.

    Killing two birds with one stone. As for the original Blackrock Panther, Su Nan casually gave it to Bured.

    “The rune stones are ready.”

    The confrontation with the Black Sword Knight had already proven the power and utility of the rune stones.

    As strong as an Advanced Knight, they could not withstand the power of a single lightning rune stone.

    Thus, over the past few days, Su Nan continuously crafted more than ten attack-type rune stones.

    Now, the number of rune stones on him has exceeded thirty.

    Definitely a hidden human-shaped artillery.

    In addition to the Hidden Dragon and rune stones, he also had spell scrolls and the Bloodvine Ring as his trump cards.

    It can be said that as long as it’s not a Legendary Knight, no matter what enemy he encounters, he at least has the ability to protect and extricate himself.

    “You plan to sell potions?”

    When Su Nan placed the potions he spent three days making in front of Brother Ke Yi, the latter was stunned.

    “Exactly.”

    Su Nan nodded, pointing at the potions and said:

    “These are diluted potions, with only about a third of the original effect, priced at approximately 70 silver coins each. We can sell them directly to the Fire Fox Commerce Association, setting the price at two gold coins.”

    Brother Ke Yi’s eyes immediately lit up.

    Although Blackstone City’s current income far surpasses before, he still often feels a shortage of money.

    If they could open up another source of income, it would undoubtedly greatly mitigate the current financial strain.

    However, soon Brother Ke Yi hesitated.

    “Isn’t the price too high?” Selling to the Fire Fox Commerce Association at two gold coins, their external price would certainly be higher.

    And a Junior Knight, unless they have a village as a fief, their total annual income would not exceed 10 gold coins.

    Would they be willing to spend a fifth or more of their annual income just to buy one potion?

    “The world is not at peace, wars are happening everywhere, especially in the Duchy of Brambleflower where the Fire Fox Commerce Association is located, where wars have been frequent in recent years. If spending a few gold coins could buy a life-saving trump card at a critical moment, surely many would be willing.”

    Su Nan picked up a potion, gently shaking it.

    “Frankly, if we had channels in the Duchy of Brambleflower, we could do this business ourselves, and the profits would be even more substantial.”

    Brother Ke Yi was moved by Su Nan’s words.

    Thinking carefully, many lords in the Duchy of Brambleflower are currently trying every means to expand their military equipment, and if an item that can enhance a knight’s strength, even temporarily, appears, it is estimated that it would cause a scramble among them.

    If you don’t buy it, what if your enemy does?

    This is a promising venture!

    “Alright, I’ll contact Mu Zhuo right away.”

    In Brother Ke Yi’s character, there is a straightforward and decisive side. Seeing the potential for profit, he no longer hesitated, quickly made the decision, and turned to dispatch someone to send a message to the Duchy of Brambleflower.

    After arranging everything, he turned back to Su Nan and asked, “Leaving now?”

    “Yes.” Su Nan nodded.

    “Stay safe.” Brother Ke Yi patted Su Nan’s shoulder, “The Starfire Cult won’t easily give up after a failed assassination.”

    Su Nan smiled and replied, thinking there’s no need to wait for them to come; my purpose this time is to seek trouble with them.

    “You be careful too.”

    Brother Ke Yi laughed heartily, “Rest assured, I am staying in the barracks, and if any assassin dares to come, I guarantee they won’t return.”

    After exchanging a few words, Su Nan left the barracks.

    He hadn’t gone far from Blackstone City when he suddenly felt a cool sensation on his face.

    Looking up, he saw the sky had begun to snow, with crystal-clear snowflakes like cold rain falling on his face.

    It’s snowing.

    Su Nan reached out to catch the snowflakes, the icy crystals gradually melting into drops of water in his palm.

    “The first snowfall of Frost Descending month.”

    Su Nan smiled slightly, with a thought, energy particles formed a faint halo over his body, isolating the snowflakes. Then he leaped onto the back of the Hidden Dragon beside him.

    “Let’s go.”

    The Hidden Dragon gave a low hiss, revealing its form and sprinted wildly across the wilderness.
