Quan Yi arrived at his office.
Regarding the weights, he planned to keep wearing them.
He would switch to heavier equipment once he fully adapted.
Quan Yi's office was much smaller than Yuan the Blacksmith's independent research institute, consisting only of a workshop and a休息室 (xiū xī shì)rest area.
Arriving at the workshop, he saw a wide workbench.
The workbench was piled with various drawings, all of which were Quan Yi's ingenious ideas and designs.
Quan Yi was not an engineering student and had no idea how to manufacture machine tools; he could only modify and experiment based on his impressions.
However, Quan Yi greatly enjoyed the pleasure of bringing the images in his mind to life.
Drawing thus became an important way for him to relieve stress.
Quan Yi organized all the drawings on the table into a册 (cè)volume and wrote 'Gun Barrel Boring Machine' on the cover.
Then, Quan Yi stored it in the Heart of the Scorching Sun.
Quan Yi still needed to send these drawings to his parents, so they needed to be carefully preserved.
"Hoo~, I'm so nervous."
Looking at the clean workbench, Quan Yi's heart became excited and uneasy.
Even when he had just finished manufacturing the boring machine, he had never been so agitated.
Quan Yi took out a strange tubular object and a delicate small wooden box from the Heart of the Scorching Sun.
Opening the wooden box, he found two transparent glass lenses inside.
Quan Yi then put on a pair of white gloves and carefully picked up one of the glass lenses.
♦ ♦ ♦ ♦
Then, he brought the glass lens close to his right eye.
"Is this the microscopic world?"
Through the glass lens, Quan Yi saw a world magnified countless times.
Such as sunglasses, telescopes, and—the microscope in front of him.
In the history of his previous life, through grinding, someone created a single lens that could magnify two hundred and seventy times.
That is to say, with just one lens, humans could enter the microscopic world.
Moreover, by stacking two lenses, the magnification for observation could be further increased.
Quan Yi put his eye to the observation lens and began to observe the table.
"Hey, is this the microscopic world? It doesn't look much different from my previous life."
Quan Yi observed the table, the wooden table, and the grain of the wood.
The magnified wood blocks looked more like countless pieces superimposed together, full of dense gaps.
In the microscopic world, everything lost its original appearance and showed a completely different appearance.
"How strange."
Quan Yi, like a child, used the microscope to observe the surrounding things.
He saw microorganisms and small bugs through the microscope.
After being excited for a while, Quan Yi sat back in his chair.
"I'll look at other things later."
Quan Yi did not forget his original purpose.
He took out a wooden box from the Heart of the Scorching Sun.
Opening the wooden box, he took out a jade skull.
This was the thousand-year head soul bone that had fallen from the attacker back then.
"Come, let me see your true face."
He pointed the microscope lens at the soul bone, probing into the mysteries of this world.
"How beautiful."
At a glance, Quan Yi saw the primordial universe, a brilliant world unfolding before Quan Yi's eyes.
Under the microscope, the soul bone revealed its true appearance.
Under the microscope, the surface structure of the soul bone was well-organized. Through the surface, inside the soul bone, thousands of fireflies flowed.
Looking closely, the structure of the soul bone showed Quan Yi a mystery of the universe. Although Quan Yi didn't understand it, he couldn't help but immerse himself in it.
"Is this the true face of the soul bone?"
Through the microscope, Quan Yi discovered that the soul bone was composed of some smaller components forming a complex structure.
"Well, I can't see anything in this state, let's try another situation."
Quan Yi input his soul power into the soul bone, and the soul bone in his hand changed from a hard object to a soft object.
This was the energy state of the soul bone.
When absorbing a soul bone, the soul master would turn the soul bone into an energy state, and then stick it on the body for absorption.
Quan Yi carefully observed the changes in the soul bone while inputting soul power.
The original stable structure suddenly collapsed, bursting out countless streamers. And it turned into a liquid-like state.
From the liquid state, Quan Yi saw tiny fragments flashing with fireflies.
The dense tiny fragments maintained a certain distance from each other, neither far away nor close. They attracted each other while also repelling each other.
"Interesting. Are these glowing fragments what make up the soul bone?"
Immediately afterward, Quan Yi stopped inputting soul power, allowing the soul bone in the energy state to return to its original state.
The originally quiet and juxtaposed firefly fragments suddenly produced violent vibrations, and then, they approached the adjacent fragments at an extremely fast speed. Then, countless fragments condensed and recombined in a peculiar way, returning to their original state.
This thing looks like memory metal.
What is a soul bone, is it bone?
Is it a bone soaked in soul power?
Or is it a block of pure energy?
After observation, Quan Yi's doubts not only did not disappear, but became more numerous.
Quan Yi pondered for a moment, then put the soul bone away.
Then he put his finger under the microscope.
"There are too few reference objects, so let me try this."
Quan Yi's finger surged with dark red light, and the ejected soul power swayed like a flame at his fingertip.
This was the color of Quan Yi's soul power.
Quan Yi wanted to compare the soul bone by observing his own soul power.
As the soul power poured out, Quan Yi saw the microscopic state of the soul power.
From the soul power, Quan Yi found rapidly moving firefly fragments, but in terms of quantity and density, they were far inferior to the soul bone.
The lens followed the moving firefly fragments, and it could be seen that they were rapidly dissipating from the fingertips to the surroundings.
"Try condensing."
Quan Yi focused his consciousness and slowly gathered the scattered soul power.
As the soul power condensed, Quan Yi could see the firefly fragments slowly approaching.
When the distance between them approached a certain level, Quan Yi felt the existence of a critical point.
Quan Yi concentrated his mind and, in one fell swoop, further condensed the soul power.
Crossing the critical point, those firefly fragments produced violent tremors, and then, they approached at an extremely fast speed.
In an instant, the fragments disappeared, turning into a regular structure.
Throughout the process, the fragments began to slowly arrange themselves in a specific pattern.
The more compressed, the more complex and compact the structure became.
Then, it finally formed an arrangement similar to the original state of the soul bone.
"Is this the formation process of 'hardness'? Why does it look so similar to the changes in the soul bone?"
