Chapter 67

Under his guidance, his spiritual power formed a brand-new spell model, more complex and exquisite than the original.

Energy was no longer simply gathered but flowed according to a specific rhythm, forming a self-sustaining vibration system.

"Just like a miniature resonance cavity..." Luo En felt this new construction method, his heart filled with amazement.

He carefully pointed this new spell model at an experimental stone on the table and then released the energy.

A ripple, almost invisible to the naked eye, shot from his palm and struck the stone.

Unlike before, this time the stone did not shatter immediately but began to emit a subtle humming sound, as if it had become a resonator itself.

A few seconds later, cracks began to appear from inside the stone, and then it silently decomposed into powder; the process was exceptionally smooth, without any signs of bursting.

【Sonic Oscillation (Proficient) Experience +3】

"Perfect!" Luo En praised softly; the effect this time far exceeded his expectations.

The newly improved sonic oscillation was not only more powerful but also more precise, capable of targeted destruction against the weaknesses of specific substances.

Theoretically, this method could even be used to target specific parts of someone's body, such as blood vessels or nerve nodes.

When he walked out of the experimental area, the night was already deep.

Luo En looked up at the starry night sky, a strange feeling surging in his heart.

After studying "The Whisper of the Star Eater," the stars were no longer just distant points of light to him, but existences containing profound mysteries.

He squeezed the stone fragment in his pocket and walked quickly toward his room.

Although it was late, it was not yet time for him to rest.

Sword art and body tempering, meditation, reviewing potion-making, spell experiments, his work at the herb shop during the day, and the potion order he promised Princess Yi Fu...

Because there were too many things to do, he could only constantly compress his sleep time; fortunately, with that pocket watch, he did not feel overly tired.

Just as that sage said: time is like water in a sponge; if you squeeze, there is always some.

………………

That day, Princess Yi Fu arrived as promised to pick up the potions she had commissioned.

Luo En had already neatly arranged all the potions on the small table, each bottle labeled with detailed information, indicating ingredients, usage, and precautions.

"The efficacy of this batch should be stronger than the last," he explained: "I added some fine-tuning to the formula, increasing the efficiency of the interaction between the medicinal materials."

Princess Yi Fu carefully inspected each bottle of potion, her expression gradually changing from focused to surprised, and finally to heartfelt admiration.

【Potion Refining (Entry-level 50/50) → Potion Refining (Proficient 1/100)】

【Additional Trait Acquired: Precise Proportioning (Efficacy slightly increased, material loss slightly decreased)】

After this period of concentrated refining, Luo En's potion refining skill had also officially broken through to the proficient level a few days ago.

This meant he could now attempt more complex potion formulas and could even begin to carry out some preliminary potion improvements.

"Next time, I can try to formulate some higher-level potions, such as 'Clarity' or 'Spiritual Shield'," Luo En suggested.

Princess Yi Fu opened her eyes wide in surprise: "Are you sure? Those are areas that even senior potion apprentices find difficult to touch. One more step forward and you'd be a professional potion master. With the time you've invested in potion-making..."

Luo En smiled slightly: "I've had some breakthroughs in potion-making recently and should be up to the task."

The brown-haired girl knew the other party did not want to say more, so she nodded and took a purse from her robe:

"This is the balance, thirty magic stone fragments, all here. Considering the quality exceeded expectations, I added five as extra compensation."

"Thank you, this is more generous than I expected." Luo En took the purse, feeling its weight.

With the completion of the potion commission, Luo En's "small treasury" had accumulated to a considerable extent—nearly 150 magic stone fragments.

This was enough to pay for some advanced courses within the school or to purchase rare materials.

"Speaking of which," Princess Yi Fu sat on a small chair to the side: "You said last time you were interested in the school's paid courses?"

"Yes, I'd like to know which courses are worth investing in." Luo En poured two cups of tea and handed one to Princess Yi Fu.

"The school's paid courses are mainly divided into three categories," Princess Yi Fu said, picking up the teacup and blowing on it lightly while beginning to explain:

"The first category is basic enhancement courses, such as 'Spiritual Power Control Techniques', 'Magic Circuit Optimization', etc. The price is relatively moderate, with each course costing about 20 to 30 magic stone fragments."

After the tea in the cup cooled slightly, she took a sip and continued:

"The second category is professional direction courses, such as 'Advanced Potion-making', 'Basic Rune Construction Principles', 'Elemental Affinity Training', etc. The price is higher, usually ranging from 50 to 80 fragments."

"The last category is for mentors to provide private guidance on your specific problems. The price is the highest, ranging from nearly a hundred magic stone fragments to several complete magic stones, but the gains are also the greatest."

Luo En listened carefully, already having a general direction in his mind: "In your opinion, which courses have the highest cost-performance ratio?"

Princess Yi Fu thought for a moment: "'Magic Circuit Optimization' and 'Spiritual Stability Techniques' would be very helpful for you at this stage. The former can increase your magic capacity and recovery speed, while the latter might reduce the spiritual pressure when using advanced meditation methods."

This was exactly what Luo En needed. Although his spiritual power value had reached 2.6, which was not too far from a medium apprentice, his magic value could not be considered outstanding, being only 0.7, which limited his spellcasting ability.

"How many fragments does each of these two courses cost?" Luo En asked.

"'Magic Circuit Optimization' requires 25 fragments, and 'Spiritual Stability Techniques' is 35. But if you sign up for both at the same time, the school will give a certain discount, totaling about 50 fragments."

He touched his chin and began to calculate: "Sounds quite reasonable. Any other recommendations?"

"If you really have talent in potion-making, then the course 'Pharmacological Resonance' might be very valuable to you. It explains how to maximize the synergistic effects between different medicinal materials and is a prerequisite course for advanced potion-making."

"How many magic stone fragments?"

"60 fragments, but for someone like you with potion-making talent, it should be very worth it. It's just that these courses generally have a cycle of about three months. If you want to choose these paid courses, you need to sign up in the next quarter, which will take about another month or more."

Having said this, Princess Yi Fu paused, hesitating whether to continue: "Also... regarding the choice of mentor, do you have any plans?"

Luo En raised an eyebrow: "Why ask this suddenly?"

"Because your progress speed is very eye-catching."

She put down the teacup and said bluntly:

"There are already quite a few people in the school talking about you. A leap from sixth-grade star talent to this level is hard not to attract attention."

The brown-haired girl leaned in slightly and lowered her voice: "I heard Ma Ge Si is very interested in you?"

Luo En nodded cautiously: "He did help me a lot before and even invited me to his laboratory for exchanges."

"Be careful." Princess Yi Fu's expression turned serious:

"The competition for the probationary wizard sequence is far more complex than you imagine. Every high-level apprentice has their own allies and opponents. If you get too close to someone, you will be implicitly drawn into these struggles."

"You are a student of Mentor Suo Lun, do you have any suggestions in this regard?" Luo En asked back.
