Moments later.
Richard stood in the street, surrounded by members of the Red Sike Gang lying on the ground, constantly screaming in agony. Some had broken legs, and some had broken arms, but they all were incapacitated.
The remaining members of the Red Sike Gang, looking terrified, felt like Richard was a monster. Meanwhile, muscular men who had broken free of the encirclement stared at Richard in shock, considering him a monster as well, but one who had helped them.
Just then, the sound of footsteps arose from both ends of the street, and numerous muscular men appeared, each wielding heavy weapons. After emerging, the newcomers first looked at their bleeding comrades and shouted, “Brothers, we’re late, hang in there!”
Then they glanced at the greatly diminished, armed men with fiery eyes and bellowed, “You Red Sike Gang bastards, how dare you ambush us, prepare to die!”
Upon saying that, the newly arrived muscular men mercilessly launched an attack. Richard saw the one leading the charge, a giant of a man—two meters tall, weighing over 250 kilograms—a muscle amongst muscles—not Baki, who else could it be?
Suddenly, Richard remembered that Baki indeed had mentioned he had a large group of brothers…
The Red Sike Gang panicked, feeling the battle was unwinnable, screaming, “We surrender—”
“No surrender!” Baki shouted out, his voice completely drowning out the Red Sike Gang members, then fiercely charged into the remaining crowd of the Red Sike Gang.
The Red Sike Gang members: “Damn it…ouch!”
…
“Bang, bang, bang!”
“Ah, ah, ah!”
The sounds of the fight and the screams quickly subsided. With Richard’s involvement, the muscle men had already severely injured the Red Sike Gang, and now with the fresh forces led by Baki joining in, they swiftly defeated all remaining members of the Red Sike Gang, claiming victory.
…
A moment later.
The muscle men cleaned up the battlefield, mainly by punching and kicking the fallen members of the Red Sike Gang to release their pent-up emotions, then tying them up, waiting for the leader of the Red Sike Gang to come and pay for their release.
In a corner, Richard was talking with Baki.
“So, these are your brothers then?” Richard asked.
“Yup,” Baki nodded. “Real brothers. I owe you big for this one; our guys would’ve been at a disadvantage otherwise.”
Richard shrugged, “Just happened to be here.”
“But no matter what, I now owe you twice. If you ever have trouble, you can count on me to handle it,” Baki said. “Even if I can’t handle it alone, the Steel Brotherhood where I belong can.”
“The Steel Brotherhood, huh… Okay, I’ll keep that in mind,” Richard replied, then asked, “But I’m curious, why did you join the Steel Brotherhood?”
“Because I was broke,” Baki spread his hands and said frankly, “In the academy, for a beginner wizard apprentice like me who really wants to learn, it’s necessary to find a way to make money, and joining a gang seemed like the best choice.

Besides, I’m thinking of buying my freedom from my betrothal to Rose. No use waiting for my King father, it’s better to make my own way—and that requires a good amount of money.”
“Ah, got it,” Richard nodded and bid farewell, “Well then, I won’t disturb you with your gang matters. I’ll be off, see you when I see you.”
“Uh, see you again when I have a chance.”
Richard turned and walked away, Baki watching him leave.
Once Richard had disappeared at the end of the street, a muscular man approached Baki and whispered, “Brother Baki, who was that person just now? Do you know him? I heard from the brothers that he seemed to have taken down half of the Red Sike Gang.”
“He’s a friend of mine,” Baki said.
“A friend?” The muscular man paused, then looked at Baki with a realization, “Oh, I see.”
Baki noticed this, glared, and slapped the muscular man on the head. Due to his height advantage, the slap seemed perfectly seamless. Baki scolded him, “A real friend, you understand! Don’t, get, any, wrong, ideas!”
“Uh, got it, got it!” The muscular man covered his head, whispering, “I understand! I understand!”
Baki: “…You understand nothing!”
…
Night, at the research facility.
In the main laboratory of the backyard, Pandora was still sleeping on a bed in the corner.
At the center table, Richard was busy.
There was an object resembling a microscope on the table—it was assembled by Richard using parts he had obtained from Alex during the day.
Typically, the earliest microscope was invented during the late 16th century on modern Earth, in the Netherlands. The more famous Hooke’s microscope, created about half a century later in the mid-17th century—specifically in 1665—was used by Hooke to observe a slice of cork, marking the first discovery of cells.
The microscope that Richard had assembled now was much more advanced than Hooke’s microscope, resembling a modern optical microscope. It featured interchangeable eyepieces, adjustable objectives, a condenser, a reflecting mirror, and a stage, among others.
Through deliberate improvements to lens quality, this microscope’s maximum magnification could reach over 1000 times with a resolution of a few tenths of a micrometer—approaching its limit—it couldn’t go any higher.
This was not a matter of tool precision, but rather a limitation of the optical microscope technology itself.
Optical microscopes used light for observation, hence the resolution limit was determined by the wavelength of visible light. When the size of the object approached the wavelength of light, diffraction occurred, hindering further magnification and causing the image to blur if forced.
The limit formula is: σ = 0.61λ/NA;
σ is the minimum resolution distance; λ represents the wavelength of visible light, generally ranging between 400-760nm among different individuals, reflecting slight individual variations;
NA or Numerical Aperture, relates solely to the objective of the microscope, not to the eyepiece. It’s a dimensionless number in the optical system, measuring the range of angles from which the system can collect light, influenced by the refractive index. When a high-refractive-index substance like cedar oil is used as a medium, immersing the objective into it, the NA can exceed 1, enabling the microscope’s resolution, σ, to reach 0.61*400nm/1.2≈200nm=0.20um.
In air, however, the NA value decreases, and the resolution is greater than 0.20um.
Of course, in most cases, such extreme resolution isn’t necessary; using it in air is sufficient.
At that moment, Richard held a Drifting Bottle, its inner wall engraved with Magic Runes, and extended a Long-handled Medicine Spoon inside to transfer some cultivated fungi out, processed them, and placed them under the microscope for observation in the air.
Rotating the knobs of the microscope to adjust the focus, Richard peered through it and murmured, “Indeed, a mutation has occurred; is it a fusion with the additive?”
After observing for a while, Richard raised his head, deep in thought.
