Dark Wizard: Rise! My undead army!

Seemingly noticing Lynn's confusion, Harold smiled smugly.

"When Thomas showed you my early works last time, your discerning eye couldn't escape my notice."

"You can spot the flaws in every single piece at a glance; it's absolutely amazing!"

Lynn then realized what was going on.

That time, he simply followed Thomas around for a day, then subconsciously analyzed each piece and looked for every flaw, not expecting that Harros had seen it all.

It seems that none of these seasoned wizards are easy to deal with. On the surface, they don't take me seriously, but in reality, my every move is under their control.

Lynn glanced at the two devices and immediately identified several design flaws and energy conflict points through [Analysis].

But he didn't want to be in the limelight.

"Master Harold is too kind," Lynn waved his hand. "I am not an expert in constructs and mechanics, so I'm afraid I can't be of much help."

"Don't be so quick to refuse!" Harold, already prepared, chuckled, pulled a bulging leather bag from his pocket, untied the drawstring, and dumped it onto the table—

Splash!

The crystal-clear standard magic stones cascaded out like a small waterfall, reflecting a dazzling luster in the dimly lit shop!

A full thousand magic stones, neatly stacked into ten piles, each containing one hundred stones, were piled between the two people.

"I know the price of knowledge and the rules!" Harold pointed to the magic stone.

"Knowledge has a price, and guidance is paid! If you can point out the problem with these two items—five hundred magic stones for one, one thousand for both!"

"As long as what you say makes sense, regardless of whether I conduct experiments to verify it later, you can take these thousand magic stones on the spot!"

He leaned closer, lowered his voice, and spoke in a seductive tone:

"Just a few words and you've got a thousand magic stones. That should be enough for you to cultivate for a while, right? If you converted that into contribution points, how many quests would you have to complete!"

Harold was very confident in his offer.

How alluring is the light emanating from this magic stone!

A newly promoted official wizard probably has more empty pockets than face, and has never seen so many magic stones before.

Lynn's gaze fell on the thousand magic stones.

Hmm... the price is acceptable.

Although it's not as good as the 28,000 magic stones stored in my Undead Ring, it's still easy money; I can get it with just a few pointers.

Making a small profit isn't out of the question...

In the future, cultivating the "Myriad Manifestations Meditation Method," raising an undead legion, purchasing rare materials... which of these wouldn't be a money-devouring behemoth?

Although I have a rich family background, the path of cultivation is long and I still need to accumulate more.

Moreover, simply "stating the problem" is sufficient; no solutions need to be provided, and no further responsibility needs to be assumed.

Seeing that Lynn did not refuse directly, but remained silent for a few seconds.

Harold's smile grew even brighter—he knew that the young, fully-fledged wizard was tempted.

"The first thing," Lynn finally spoke, pointing to the spherical core.

"Your design idea for the 'Adaptive Soul Energy Stabilizer' is to use the central crystal as a soul energy buffer pool and adjust the rune output frequency through gears to achieve dynamic stability, but there are three problems."

Harold immediately sat up straight and took out a bone plate, ready to take careful notes.

"First, the 'Dark Bloodstone' attribute of the central crystal has a natural phase difference with soul energy..."

"Third, and most importantly," Lynn pointed to an inconspicuous rune connection point on the core shell.

"You used the 'Soul Binding Rune' here to strengthen the structure, but this rune will create a hidden conflict with the internal 'Energy Flow Rune'. Continuous operation will cause the conflict to accumulate and lead to core overheating, or even an explosion."

Harold's pen flew across the paper as he wrote, beads of sweat forming on his forehead.

Some of the problems Lynn pointed out were ones he had vaguely sensed but couldn't pinpoint precisely, while others were completely unexpected!

"The second item, the 'Multi-functional Ghost Iron Combat Arm'." Lynn turned to the mechanical arm. "The problem is even more obvious."

"The material itself has a natural attenuation in energy conduction. In pursuit of strength, you exceeded the thickness limit for the main structure of the arm, and further increased it..."

"...Therefore, this arm will disintegrate from the inside within three seconds."

After saying that, Lynn leaned back in his chair and said nothing more.

The shop was completely silent.

Harold stared blankly at his notes, then at the two pieces of work he had been quite proud of on the table, his face turning pale and then flushed.

After a long while, he finally let out a long breath, shaking his head with a wry smile: "So that's how it is... so that's how it is... no wonder I always felt something was off when I was testing, but I couldn't figure out why..."

He looked up, and the look in his eyes as he gazed at Lynn had completely changed, now filled with genuine admiration and awe.

"Master Lynn, no, Lord Lynn... I admire your discerning eye." Harold pushed the thousand magic stones in front of Lynn.

"This is yours. As for whether what you said is correct... I'll verify it with experiments later. But just because you could spot so many details at a glance, this thousand magic stones are worth it!"

Lynn didn't stand on ceremony and waved his hand to put the magic stone into his spatial ring.

Harold rubbed his hands together, leaned closer, and said eagerly, "Lord Lynn, you see... could you perhaps find some time to come and visit me every now and then?"

"I won't trouble you too much, just take a look at my new pieces. The price will remain the same as today's, five hundred per piece, no upper limit! How does that sound?"

Lynn smiled wryly: "Master Harold, I'm afraid I don't have that much time. I've already accepted a posting and will soon be leaving the academy for the main world."

"A garrison mission?" Harold was taken aback, then waved his hand dismissively.

"So what! Don't the resident wizards get a month's vacation each year to go back to the academy?"

"Just take a day, no, half a day, to come over! I'll reimburse your travel expenses! No, I'll even give you an extra hundred magic stones for the journey!"

He stared at Lynn expectantly, like a short, fat groundhog waiting to be fed.

Travel expenses? This old rascal is really sincere; he even reimbursed his return trip to the academy...

Lynn was silent for a moment, then finally nodded: "If I have the chance, I will come."

"Then it's settled!" Harold was overjoyed and quickly took out a specially made bone fragment communication talisman from his pocket, presenting it with both hands.

This thing is like a "business card" from another world.

"This is my personal communication token. Let me know in advance when you're coming back, and I'll prepare some tea and snacks to welcome you!"

Lynn gave an awkward smile.

"I've just been promoted and haven't purchased a communication device yet."

The Soul Crystal Nameplate does have a communication function, but it is only used when the academy issues notices, and it is a one-way communication device.

Harold waved his hand.

"Keep it for now, we can contact you directly once we have a communication device."

His shop doesn't produce these kinds of communication gadgets, otherwise he could have just given Lynn one.

Lynn then took the bone fragment, put it in his pocket, and prepared to buy a communication device later.
