A moment later.

Richard stood in the street, surrounded by a large number of people from the Redsk gang lying on the ground screaming, either with broken legs or broken hands, all incapacitated to fight.

The rest of the Redsk Gang looked at Richard with a horrified expression, thinking that it was simply a monster. And the muscular men who broke away from the encirclement in the distance looked at Richard with shock, feeling that Richard was also a monster, but a monster who helped them.

At this moment, footsteps sounded in both directions of the street and the end of the street at the same time, and many muscular men rushed out, all armed with heavy weapons. After rushing out, the new muscular man first looked at his bleeding companion and shouted, "Brothers, we're late, hold on!"

Then he looked at the people who had been reduced by half and were armed with weapons, and roared with red eyes: "The bastards of the Redsk Gang, dare to sneak attack us and take their lives!"

As the words fell, the new muscular man launched an impact mercilessly, and Richard saw that the person who rushed to the front, two meters tall and weighing two hundred and fifty pounds, was the muscular man among muscular men - not Bucky, who else would it be.

Richard suddenly remembered that Bucky had indeed said before that he had a large group of brothers......

The people of the Redsk Gang panicked, feeling that this battle could not be fought, and shouted: "We will ...... it"

"No surrender!" Bucky shouted, his voice completely overshadowing the Redsk Gang before slamming into the rest of the Redsk Gang.

Someone from the Redsk Gang: "Nima...... Ahh

......

"Bang bang bang!"

"Ahhh

The sound of battle and screams quickly subsided, and due to Richard's participation, the muscular side had already caused great damage to the Redsk Gang, and now the new force led by Bucky joined in, quickly defeating all the remaining Redsk Gang and winning the victory.

......

Moment.

The muscular men clean up the battlefield, and the main content is to punch and kick the Redsk gang who have fallen to the ground to vent their emotions. Then they were tied up one by one, ready to wait for the leader of the Redsk gang to come and pay for the ransom.

In the corner, Richard and Bucky were talking.

"So, these are your brothers?" asked Richard.

"Hmm. Bucky nodded, "A real brother." I still have to thank you for this incident, otherwise our people will suffer. ”

Richard shrugged: "It just happened." ”

"But no matter what, I owe you two favors, if there is any trouble, you can find me, and I will definitely help you deal with it. "Even if I can't do it myself, my Brotherhood of Steel can." ”

"Brotherhood of Steel...... Well, something will come your way. Richard said, then asked, "But, I'm curious, why did you join this Brotherhood of Steel?"

"Because I don't have any money. Bucky spread his hands and said calmly, "In the academy, a beginner wizard apprentice like me, if you want to really learn something, you always have to find a way to make money, and joining the gang is obviously the best choice for me."

Besides, I'm still thinking about redeeming myself, I don't want to be Ruth's fiancé for the rest of my life. My king's father didn't have to think about it, or did he have to figure it out himself, and that would require a lot of money. ”

"Well, okay, I see. Richard nodded and said goodbye, "In that case, I won't bother you to deal with the affairs of the gang, I will leave first, and I will see you again when I have a chance." ”

"Well, there's a chance to see you again. ”

Richard turned and walked to the side, and Bucky watched Richard leave.

When Richard disappeared into the end of the street, a muscular man walked over, looked at Bucky, and asked in a whisper, "Brother Bucky, who is that person just now, do you know?" Just now, I heard from my brothers that he seems to have helped us defeat half of the Redsk Gang. ”

"That's a friend of mine. Bucky said.

"Friend?" the muscular man was slightly stunned at first, then looked at Bucky with a "I see" expression.

Bucky noticed it, his eyes widened, and he slapped the muscular man on the head. Because of the advantage of height, this slap looks like there is no sense of disobedience. Bucky said, "It's a real friend, you know!

"Uh, I understand!" the muscular man covered his head and whispered, "I understand!

Bucky: "......" You know the hell!

......

Night, laboratory.

In the main laboratory in the backyard, on the bed in the corner, Pandora was still asleep.

At the table in the middle, Richard was busy.

On the table, there was a delicate microscope-like thing that Richard had assembled from parts he had obtained from Alex during the day.

Generally speaking, the microscope in the earliest sense is made by the Dutch in the late 16th century on modern Earth. The more famous Hooke microscope was made in 1665 in the middle of the seventeenth century, and was used by Hooke to observe cork slides, and the existence of cells was discovered for the first time.

The microscope assembled by Richard is much more advanced than the Hook microscope, and is more similar to the modern optical microscope. There are interchangeable eyepieces, adjustable objectives, condensers, reflectors, stages, and more.

This microscope has been deliberately improved by Richard to improve the performance of the lens, and the ultimate magnification can reach more than 1,000 times, and the resolution is in the order of a few tenths of a millimeter, which is close to the limit - it cannot be higher.

This is not a question of the precision of the tool, but the limitation of the application technology of the optical microscope itself.

It is called an optical microscope because it uses light to observe. Therefore, the resolution limit is determined by the wavelength of visible light, and when the size of the object is close to the wavelength of light, diffraction of light will occur, and it cannot be further amplified, and forced amplification is also blurred.

And this limit formula is: σ = 0.61λ/NA;

σ is the minimum resolution distance, λ is the wavelength of visible light to the human eye, generally between 400~760nm, the range of some people is slightly larger, and the range of some people is slightly smaller, with certain individual differences;

NA stands for Numerical Aperture, which is the numerical aperture of the objective lens - the magnification of the microscope is only related to the objective lens, not the eyepiece.

It is a dimensionless number in an optical system that measures the angular range of light that the system is able to collect, affected by the refractive index. When using a substance with a high refractive index as a medium, such as immersing the objective lens in cedar oil, the NA value can be greater than 1, then the resolution of the microscope can σ reach 0.61*400nm/1.2≈200nm=0.20mm.

In air, the NA value decreases, and the resolution is greater than 0.20mm.

Of course, in most cases, there is no need to pursue extreme resolution so much, it is enough to use it in the air.

At this time, Richard held the drifting bottle with magic patterns engraved on the inner wall, put a long-handled medicine spoon into it, removed some of the fungi cultivated inside, processed it, put it in the microscope, and observed it in the air.

Turning the knob of the microscope and adjusting the focal length, Richard looked at it with one eye and muttered: "Sure enough, there has been a mutation, is it a phenomenon of fusing additives?" ”

After looking at it for a while, Richard looked up thoughtfully.
